    If the nozzle 2 is positioned somewhat away from the top of the casing of the wash column in order to provide a small space between the outlet and the top, a stable interaction surface between the suspension and the used flushing liquid forms under the outlet of the nozzle 2. On said surface, the interactions of the suspension and the spent washing liquid are separated from each other. Thus, the part forming the interaction surface is used as a distribution zone for the suspension of the spent washing liquid.
    Under the ensuring dispersion by dispersing element 3, there is an upward supporting section 5 of body I (washing zone L) of the column, above which a deposition (separation) zone B located in the upper part of the column housing 1 is placed, and the connecting zone B. A uniformly dispersed area is given in contact with an upstream countercurrent flow of washing liquid in these zones, resulting in a washing of the suspension.
    In the lower part of the support section 5 of the casing 1 of the wash column, a series of nozzles are installed, each of which has a small opening — an exit slit for supplying the flushing liquid into the casing 1 of the wash column. The nozzles 4 provide a supply of washing liquid up through the wash column. In order to avoid turbulence in the wash column, the exit slits of the nozzles 4 are set obliquely to the horizontal plane and directed towards the bottom of the housing 1.
    An outlet opening 6 for the washed slurry is made in the wall of the washing column 1 at its bottom. It passes through at a point located in the lower part of the column housing (i.e., in the cone-shaped part D) of the washing column. Through this opening 6, a naturally precipitated suspension is removed after washing it. To prevent turbulence in the fluid flow inside the industrial

    Each hundredth 4 contributes to the stabilization of the flow of liquid flow within the washing column. In addition to the exit |, p slots, guiding means such as a ceramic grid, a piece of cloth or a screen (not shown) could be provided in the nozzles 4. In the upper part of the c. -Pusp 1, the upper pyshodny opening 7 is made through its wall to remove the washing liquid. The nozzles 4 are connected to the line 8 supply of washing liquid.

However, the real values of the 1P1I flow rates of the suspension and G1p (1-part fluid can vary significantly depending on the physical properties of the solid material and the fluid.
    The proposed wash column, for example, for washing a suspension of synthetic resin, works as follows.
    The specific gravity of the CHHTCI resin is similar to the specific gravity of the phosphorus carbonate, bone, as which water or organic solvent can be used. , 1c particles of synthetic freedoms1 About pechuschuts in suspension, nonroNiy TpvV r.Ho ensure the penetration of the bol1, - I jiix (1b7 -.eme synthetic resin by the tm1 holiday method.

However, the polymer obtained according to the bulk polymerization method contains boiling n-heptane soluble polymers and catalyst residue in high concentrations.
    The physical properties of a polymer containing a solvent in boiling n-heptane polymers in high concentrations are degraded, especially with respect to stiffness, stress, etc. Accordingly, the characteristic properties of polypropylene are degraded; it is virtually impossible to use ultrasound in cases where relatively high physical properties are required.
    The method of volume polymerization of 7C {Isiol-Esotsia allows reducing the amount of catalyst remaining in the substance, since the rate of polymerization is higher than the full-scale method in a solvent and polymerization can be carried out under conditions that are effective for the use of the catalyst. However, taco also cannot be used in cases when it is required; - it is of low quality, but it can not be matched; the breechiness and color do not correspond to the standard of tsrsiuomi--. For these reasons, in practice, soluble n boiling c-heptane polymers and catalyst residues are removed from each propylene polymer or copolymer obtained by polymerization.
    The polypropylene slurry is introduced into the wash column through the nozzle 2. Dispersant element 3 is arranged; : En1c, 1st under nozzle 2, evenly disperses the slurry through the column and reduces the slurry flow rate, resulting in a stable interaction surface between the slurry and the developed washing liquid, which prevents the occurrence of a turbulent slurry flow into the supports

    Pom plot 5 Corps I wash wash. The flow rate of the suspension is clearly correlated with the state of the interface and the turbulence of the suspension in the support section 5 of the MIJ production column. Since the flushing efficiency for polypropylene decreases significantly with increasing flow scopes, the latter is limited to 0.5 m / s or less, preferably 0.1 m / s or even less. The efficiency of the flush increases with decreasing rate of suspension introduction.
    The diameter of the dispersing element 3 influences the likelihood of excluding dynamic pressures in the slurry. With a diameter of the diameter, the growth of the dispersing element 3 becomes large. However, the diameter of the dispersing element 3 should not significantly increase, since the average speed of the two flush top of the flushing fluid in the annular section of the cross section between the dispersing element 3 and the inner wall of the casing 1 of the countercurrent washing column increases and begins to transform from 1-1П1 to the average value of the flow velocity. inoA fluids in the horizontal cross-sectional plane in the washing zone A, which worsens the conditions for the deposition of polypropylene particles and sposs) arises from the occurrence of i in tuberculosis. The diameter of the dispersion-iiiCi of the e.1-element 3 is 0.1-1.5. n; approximately 0.5 - 1.0, the diameter oiioiiHuro of section 5 of the hull 1 of the TO4Hoji promt, 1 in the column.
    The industrial fluid containing the propylene in the mainstream is introduced into the lower part via the supply line 8 through the nozzles 4 in order to facilitate its dispersion. It is desirable to have in each of the exit slits a ceramic grid, a piece of cloth or a screen, for example a weeding grid. The flow rate during the washing of propylene fed through the nozzles 4 is clearly correlated with the stability of the boundary section formed between the suspension and the used washing liquid in the upper part of the housing 1) in the column and the degree of turbulence of the suspension in the washing zone L. Since efficiency
    Reducing the flow rate of the flushing fluid to a value of 0.2 m / s or less, preferably to 0.05 m / s or less, In addition, the o67jeM suspension, from which no solids are removed, increases in case when the velocity of the upward flushing fluid stream forms the boundaries of the interaction between the slurry and the flushing fluid in the wash column.
    A synthetic resin slurry, e.g., a polypropylene slurry, can be npoMi.iTa countercurrent-i in large volumes with good quality of washing and a high percentage of synthetic resin recovery by using the proposed industrial burner column and ensuring such a mode of operation that allows for better conditions described above.
    Example (control), Suspension preparation: AI polypropylene.
    A vibratory mill equipped with a tank (internal volume of 700 liters) was used, which contained 2300 kg of steel balls with a diameter of 12 mm. 60 kg of magnesium chloride was introduced into the container under a nitrogen atmosphere. 12 liters of tetraethoxysilane and 9 liters of 1,2-dichloroethane. The contents of the container were milled for 12 hours. Then, 36 kg of the ground mixture and 240 l of titanium tetrachloride were loaded into a thoroughly dried mixing bag (internal volume of 600 l) in a nitrogen gas atmosphere. The contents were stirred at 80 ° C. for 120 minutes and then kept. The resulting supernatant was removed. Then 420 l of n-heptane was added, the mixture was stirred at 80 ° C for 15 minutes and kept. Remove the vip-nip layer.

    Example 1. Washing the propyl suspension was carried out in an anti-wash column, the dimensions followed with a leaching: the inside diameter of the washing zone is 80 cm; length of wash area A 500 cm; inner diameter of the zones, 1B sedimentation of the suspension 120 cm; the length of the precipitation zone B is from — where the suspension is 200 cm; the height of the part is 100 cm; the height of the junction ei oiu.i B between the Bepxiieii zonoGg B sedimentation-branch1 and, n zone A prom, that 1i-branch | 70 cm; the diameter of the bottom surface of the conical core of the first displacement of the suspension of the dispersing element 3, located under the nozzle supplying the suspension, 2, 60 cm; the diameter of the outlet of the nozzle 2 for the introduction of a suspension of polypropylene, which is subjected to washing, 1 inch (2.5 cm); nozzle diameter 2 6 inches (15.24 cm).
    The washing propylene was introduced via line 8 into the countercurrent wash column through nine sintered cylindrical nozzles A, as shown in FIG. 2 in order to disperse the washing liquid. Each of the nozzles 4 has a structure corresponding to that shown in FIG. 3. The washed suspension was removed through the outlet opening 6, and the spent washing liquid — 1) without the outlet opening 7. When using the specified column, the suspension, floor 1-non 1 in the example used as a control, was introduced along the feed line of the nozzle 2 with a speed 1880 kg / h (like polypropylene) and with a flow rate of 0.06 m / s to the inside of the column through nozzle 2. At the same time, propylene used as washing liquid was fed through a line in the amount of 2900 kg / h at a flow rate of 0.01 m / s into the column through the nozzles 4. Washed Susp It was removed in an amount of 1880 kg / h through the outlet opening 6, while the spent propylene was removed in the amount of 2900 kg / h through the upper outlet opening 7 intended for the washing liquid. The washing was continued for 2 hours, during which it was carried out the regulation of the supply of the suspension and propylene, as well as the removal of the washed suspension and recovery of the multi propylene at the above levels. Then, to determine the efficiency of the powder, the powder obtained by drying the suspension prepared by F according to the example used as the control, the supernatant layer being removed when the stirring process in the autoclave, the same as the one being performed, and powder obtained by drying the slurry.
    The parameters analyzed were the intrinsic viscosity (l) of the powder obtained by drying the suspension prepared in the control example, the residue (in percent) of the polymer after extracting it with boiling n-heptane, calculated as the ratio of half a polymer after extraction / polymer before extraction X 100% (denoted by T T)
    A1, Mg and methyl-p-toluylate.
    Mixing in the autoclave was stopped and the expanded layer was separated, removing it from the autoclave during the implementation of the test example.
    The nonvolatile components (dissolved polymer + dissolved ash), A1, Mg, and methyl p-toluylate present in the surface layer were analyzed. In addition to 11, A1, Mg, and methyl p-toluylate were also analyzed in the powder obtained by drying the washed suspension. The results are presented in table. I.
    Based on the analysis data A1 and Mg,
    present in the powder, as well as non-volatile components present in the supernatant, calculate the percentage of A1 dissolved in propylene relative to the total amount of aluminum based on the data from table. G:, 3%.
    Similarly, the percentage of Mg dissolved in propylene, in relation to the total amount of Mg,
    amounted to 78.2%.
    The supernatant was dried in order to determine the weight of the polypropylene dissolved therein. It was established that the amount of soluble propylene corresponded to 1.4% of the entire 1-1-meter pol. Assuming that methyl p-toluylate is fully attached to the dissolved polypro-, present in the device
    for polymerization, the concentration of methyl-p-toluylate thus added was calculated by the equation
    ., 058, 0,, dh per million
    Thus, the percentage of the remaining elements in the dissolved parts of the purified polymer was: AI 1.3%; Mg 2.0%; methyl p-toluylate 1.5% and a soluble polymer 2.0%.
    Therefore, the cleaning efficiency is 98.7% for AI, 98.0% for Mg, 98.5% for methyl-p-toluylate and
    100% of the soluble polypropylene In the mid-range, the cleaning efficiency is 98.8%.
    The percent recovery of polypropylene for the amount of half-gravel and Kai-alizer residue that were removed by spent propylene with BNtecTe was determined by evaporating the spent polypropylene to obtain a dry substance. As a result, it was found that the percentage recovery of polypropylene was 98.4%.
