    The disclosed apparatus is of the type in which feed units feed air and hydrocarbon material into a reaction chamber, where they react to form carbon black. A filter then removes the carbon black. Disclosed is the provision of a mixing chamber between the feed units and the reaction chamber. The mixing chambers pass through a demountable hollow reactor cover through which there is circulated a heat transfer fluid for controlling the temperature of the mixing chamber walls. The mixing chamber can be common to a plurality of feed units or be separate for each feed unit. Also disclosed is a feed unit which has a vortex plate, an output nozzle, and a hydrocarbon spray nozzle, all mounted on a hydrocarbon supply tube which in turn is fixed to a demountable cover of the feed unit. This permits these components to be readily removed with the cover for replacement or service. The feed units can also have their temperature controlled by the heat transfer fluid for the mixing chambers.

    This invention relates to a process for producing carbon black, and more specifically to a plant for producing various types of carbon black.
    A known installation for treating soot containing successively installed mixing chambers with means for supplying fuel and air for burning fuel, a reaction chamber (for heat treating channel soot), a quenching chamber and a collector for. collecting soot ij.
    The disadvantages of the installation are the lack of cooling of the mixing chambers and the possibility of obtaining (processing) only one type of carbon black and of processing only gaseous hydrocarbon.
    Closest to the present invention is a plant for the production of carbon black, containing successively installed a mixing chamber with means for supplying air and hydrocarbons, a reaction chamber, a heat exchanger for cooling the carbon black products and a separation apparatus.
    Since in order to obtain carbon black with different particle sizes in this ety installation, a different proportion of air is needed in terms of volume, the thermal load and, consequently, the temperature of the mixing chamber is maintained at different levels, which leads to negative consequences in the manufacture of various types of carbon black.
    The purpose of the invention is to simplify the production of various types of carbon black by controlling the temperature in the mixture chamber.
    This goal is achieved in that the installation for producing soot with ;-) holding a successively installed mixing chamber with means for supplying air and hydrocarbons, a reaction chamber, a heat exchanger for cooling soot-gas products, and an apparatus for separating soot are equipped with an additional heat exchanger located around the mixing chamber. ;
    The additional heat exchanger is connected by pipeline to the heat exchanger for cooling the soot-gas products.
    The means for supplying air and hydrocarbons contain a sequentially and coaxially mounted air chamber, a diaMefp guide pipe which is smaller than the diameter of the air chamber, a sleeve and an outlet pipe, a vertical hydrocarbon supply pipe installed along the longitudinal axis of the air chamber, and an orifice mounted there in the pilot pipe perpendicular to the longitudinal axis and mounted on the hydrocarbon supply pipe.
    The free cross-sectional area of the outlet pipe is equal to the free cross-sectional area supplied with openings of the partition.
    Thanks to temperature control, it is possible to install teraratur in a mixing chamber, regardless of the type of soot obtained in a given case, and to maintain it during a certain production process at a constant level.
    If the additional heat exchanger is piped to the heat exchanger to cool the carbon dioxide products, heated air can also be supplied to the mixing chamber.
    If the means for supplying air and hydrocarbons contain a sequentially and coaxially mounted air chamber, the guide tube, whose diameter is less than the diameter of the air chamber, the sleeve and the outlet
    a pipe, a vertical pipe for supplying hydrocarbons, installed along the longitudinal axis of the air chamber, and a partition equipped with a hole, installed in a guide pipe perpendicular to the longitudinal axis, and fixed on the pipe for supplying hydrocarbons, then this achieves an intensive mixing of both components - air and hydrocarbons As a result, the free oxygen in the air is completely combined with a portion of the hydrocarbons. This provides soot of the required quality.
    If, in addition, the free cross-section of the outlet nozzle is equal to the free-iy cross-section of the partition-wall fitted with openings, then an extremely large turbulization of the supplied air is achieved.
    Ba figure 1. shows the reactor, a vertical section; figure 2 -. of the reactor with a modified mixing chamber, vertical section; on fg.Z - reactor lid with means for air supply, top view in FIGS. 4 and 5 — section AA — in FIG. 3 p with a single mixing chamber and with a chamber divided into separate chambers, respectively} in FIG. 6 - air and hydrocarbon supply means, vertical section; . 7 is a reactor with a heat exchanger embedded in the wall, a horizontal section.
    The device for soot extraction has sequentially installed a mixing chamber 1, on which means 2 for supplying air and hydrocarbon feeds are installed), a reaction chamber 3, pulling & shire to the reaction chamber 3 a heat exchanger 4 for cooling the resulting soot-gas products and connected via pipeline 5 apparatus b for the separation of soot and gas. Apparatus b has two pipelines 7 and 8 for gases and for removal of the soot produced. . The mixing chamber 1 is part of a cover 9, by means of which the reaction chamber is closed from the side of the upstream.
    Means 2 pits are located on the upper side of the cap 9 and serve to supply hydrocarbons and reactive air. .
    A heater 10 is located around the mixing chamber 1 and is connected by a pipe 11 to a heat exchanger 4 for cooling the soot-gas products. .
    Mixing chamber 1 may be made differently. It can (Fig. 4) Contain a certain number of nozzles 12 in which the power supply means 2 are included. The mixing chamber 1 liter (Fig. 5; consist of several chambers separated from each other.
    Means 2 for powering air and hydrocarbons contain coaxially mounted air chamber 13, guide tube 14, the diameter of which is smaller than the diameter of the air chamber 13, sleeve 15 and outlet nozzle 16. Along the longitudinal axis, a vertical tube 17c is mounted with a spray gun 18, on which the reinforced partition-mounted partition 19, mounted in the direction of the injector 14, is perpendicular to the longitudinal axis of the air chamber 13.
    The area of the free 5; the outlet nozzle 16 is equal to the free section area of the partitioned hole 19.
    The installation works as follows.
    Hydrocarbine chamber 13 B1 enters the hydrocarbon through the supply means in the vertical pipe 17 and the air through the pipeline 20, and the air is supplied from the reservoir 21 (Figures 1 and 3) through separate pipelines to each supply means.
    In the mixing chamber Ks1mere 1, the two components are thoroughly mixed and the hydrocarbons are gasified. The gas mixture arising in the mixing chamber I is directed to the reaction chamber 3 and ignites here; one part of the hydrocarbon is burned and creates the temperature required for the reaction to form a sediment, while / from the remaining hydrocarbons soot is formed.
    In the heat exchanger 4, the carbon black products are cooled and fed through conduit 5 to the device 6 for separating soot and gases, from which gases are discharged through the evacuating conduit 7, and soot - through the evacuating conduit 8.
    The medium, for example, air or water, is supplied to the heat exchanger 10 arranged around the mixing chamber 1 through pipe 11. It can be connected to the heat exchanger 4, with the result that the heat exchanger 10 can serve both to cool and to heat the incoming air and hydrocarbons.
    To regulate the temperature (see Fig. 7 by removing or supplying heat in the wall of the reaction chamber 3, a channel 22 with heat-conducting surfaces is provided, the medium being supplied through nozzle 23, and the withdrawal through nozzle 24.,
     Using the proposed device, an impeccable maintenance of the required temperature conditions in the area where the mixing of carbohydrates with air takes place is achieved. Due to this, the number of soot types can be expanded without disrupting operation. The increase in costs required for this, caused by the installation of an additional heat exchanger 10 in Krayake 9, is insignificant compared to the benefits obtained.
    In addition, the additional heat exchanger 10 contributes to the lengthening of the service life of the power means 2, in particular their parts most susceptible to wear, for example, nozzles 18, and ensures continuous operation of the installation.
    The combustible waste gas discharged through line 7 can be cleaned or incinerated if necessary.
