    A method and apparatus for sealing the drive end of a chamber for the preparation and hydrogenation of coal with hydrogen to form hydrocarbons in which the chamber comprises a hollow cylinder with a rotatable element therein having a conveying web thereon and in a sealing region a pressurized sealing substance such as coal particles mixed with oil is fed from a storage container through a feed passage into an annular recess at a pressure higher than that in the chamber so that the scaling substance passes through a conical annular gap which tapers towards the chamber. A further narrower gap on the drive side of the recess leads to a further annular recess from which the sealing substance can be extracted through a return pipe. Pressure comparison means control the feed pressure in the feed passage. The recesses and the annular gap can be provided by machining the rotatable element rather than the hollow cylinder and forward feed screw forms may be provided on the rotatable element in the sealing region.

    intermittently pushed into the preparatory. pressure chamber in. pressure in the indicated chamber.
    In the device for loading coal into the hydrogenation chamber to produce hydrocarbons, including a feed funnel and a preparatory chamber with friction elements mounted on the shaft, the shaft in the direction from the feed funnel to the drive is made tapering conical and has an annular semicircular groove, the preparatory chamber is equipped with a bunker and pipe feed coal in a pasty form, the outlet of which is located opposite the groove connected to the compressor or auger.
    In addition, a thread, a cylindrical surface, the diameter of which is made close to the inner diameter of the chamber, and an annular semicircular groove, and the chamber are provided with an additional pipeline, one end of which is opposite to the groove, and the other end connected to the hopper, are made on the back of the groove.
    The conical surface of the shaft is made with a diameter less than the diameter of its cylindrical surface.
    In the wall of the preparatory chamber, on the drive side, channels for supplying the heat transfer medium are made.
    By continuously supplying the sealing medium in the form of raw coal or materials of the sheath material having similar properties, the seal is constantly updated without inevitable wear and tear and the downtime for assembly and disassembly 14a for new seals is associated with this, which allows to maintain the required pressure in the chamber and thereby increasing the efficiency of the process.
    The proposed shaft arrangement allows the necessary seals to be created and maintains the high pressure required for the hydrogenation process.
    FIG. 1 shows a plant for hydrogenation of carbon with hydrogen to hydrocarbons, longitudinal section; n FIG. 2 - shaft with friction elements; in fig. 3 - preparatory chamber from the drive side of the friction elements.
    The device for loading coal into the hydrogenation chamber 1 includes a feed hopper 2 with a valve 3 and
    Gateway 4 with dosing drum. The feed funnel 2 is connected via a feed opening 5 to a preparatory chamber 6. In the preparatory chamber 6 there is a shaft 7 with friction elements 8 equipped with a rotational drive. The shaft 7 with the friction elements 8 continues in the direction of the chamber 1 hydrogenation as a rotor 9 with rotor blades 10 mounted on it.
    Through the housing 11 of the chamber 1 in a radial and axial directions at equal distances in the direction of the axis of the rotor 9 emerge static mixing nozzles 12 with check valves 1i. The static mixing nozzles 12 are also connected to the hydrogen supply system 13, which is supplied with hydrogen by means of a hydrogen source and a compressor 14. The shaft 7 in the direction from the inlet 5 is made tapering conical and has a semicircular annular groove 15 - Preparatory chamber 6 by a hopper 16 and a coal supply pipe 17, the outlet of which is located opposite the groove 15 connected to the compressor 18 or screw 19. On the shaft 7 behind groove 15 is made + a thread 20, a cylindrical surface 21, the diameter of which is made close to the inner diameter of the chamber 6, the annular semicircle groove 22. Preparatory chamber 6 is equipped with an additional pipeline 23, one end of which is located opposite the groove 22 and the other connected to the hopper 16.
    The method and operation of the device is carried out as follows.
    The original coal, for example, milled and mixed with oil, is continuously pumped from the bunker 16 through the pipeline 17 under pressure from the compressor 18 connected to the bunker 16 to the first annular groove 15. From there, the fed coal through the 2k threading thread 2 enters the preparatory narrowing camera 6 conical annular gap formed by the body 25.
    The conical or cylindrical shape of the annular gap in the direction of the preparatory chamber 6 causes a corresponding high pressure. In addition, the conical shape of the annular gap ensures that it is filled with the original coal evenly around the perimeter. Since the pressure, starting from the compressor 18, through the supply pipe 17 is set higher than the pressure that prevails in the preparation chamber 6, plastic coal is supplied by a conical, kim-sealing body 25 and flows into the preparation chamber 6. And since the pressure in the sealing zone maintains a constantly higher pressure in the preparatory chamber 6 as compared to the pressure, the conical sealing body 25 is continuously supplied to the preparatory chamber 6. tightness with respect to its transmission and counter bearing in relation to high pressure in the preparatory chamber 6. The seal can be strengthened by making the second annular groove 22, which is also connected by pipeline 23 to the hopper 16. Starting from the first annular groove 15 on the side the drive near this groove is made of a reverse flow causing locking thread 20, which is flanked by a cylindrical surface 21. The pasty original coal, which is large. The pressure of the compressor 18 through the feed pipe 17 enters the annular groove 15 and flows to the end from the drive side, through the locking thread 20 is fed back into the annular groove 15. If no reverse flow is obtained, then the original coal under pressure an annular groove 26 flows through the second annular groove 22. From here, the original coal is conveyed back to the bunker 16 by pipeline 23, where it is re-pressurized by means of a compressor 18 and fed back to the first annular canal 17 The 15P house with a second annular groove on the drive side is additionally provided with a friend, causing a round feed, locking thread 30 so that the original coal does not fall on the drive side of the drive shaft 7 from the drive side and to create pressure in chambers 1 and 6. The pressure is regulated by means of a pressure measuring device 27, which probes the pressure in the preparatory chamber 6. Both pressure indicators are compared with each other by means of a regulating device 28, and 8 according to these indicators, the pressure produced by the compressor 18 is adjusted so that the pressure in the respective annular grooves 15 or 22 are higher than in preparatory chamber 6. Due to this, firstly, the pressure in preparatory chamber 6 is constantly maintained at the same level, and secondly, and Khodnev coal can not penetrate to the end of the transmission from the friction element and lprotivoupornogo bearing provided there. To prevent the temperature from being transmitted to the actuator, spiral channels 29 are provided to maintain a uniform temperature, which are circulatingly charged using a system to maintain a uniform temperature (not shown) and serve to heat it. time of starting phase or cooling during further operation. If a compressing screw 19 is used to create pressure in the corresponding first annular grooves 15 or 22, the regulating device 22 adjusts the rotational speed of the compressing auger 19, and thereby the pressure in the corresponding ring of the Target grooves 15 and 22 in such a way that it prevails) but a higher pressure than the pressure in the preparation chamber 6. The pipelines 17 and 23, as well as the hopper TB and the compressor .18 or the compressing screw 19 can alternatively also be installed above the drive side. Such an installation is advantageous, This is particularly helpful in facilitating the process of supplying initial carbon to the annular cavities 15 and 22.. Such an implementation of the method with. The use of the proposed device allows the preparatory chamber to be compacted and the necessary pressure maintained therein, which increases the efficiency of loading and operation of the hydrogenation chamber.
