SU319233A1 - Reactor for producing carbon black - Google Patents

Description

yeh

The invention relates to the chemical industry, namely to devices for producing carbon black.

A soot reactor for producing soot is known, consisting of a combustion chamber, along the axis of which a raw nozzle, a reaction chamber, a mixing nozzle, an air chamber and burner devices located concentrically relative to the raw nozzle are movably mounted.

However, the known reactor does not allow an increase in the soot yield and has a production capacity for raw materials. In addition, the use of liquid fuels reduces the intensity of the combustion process and reduces the soot yield.

The purpose of the invention is to increase the productivity and reliability of the reactor, increase the soot yield, intensify the process; this is achieved by placing one or several raw nozzles for the mixing nozzle, for example, burner tubes are placed inside the cylindrical body of the air chamber,

FIG. 1 shows a reactor, a longitudinal section; in fig. 2 - burner, section.

The reactor contains a chamber 1 of throat along the axis of which the raw nozzle 2 is movably mounted, the diaphragm 3 with the mixing nozzle 4 and the reaction chamber 5. In the mixing nozzle one or several raw nozzles 6 radially set.

At the end of the combustion chamber 1, an air chamber is installed with a cylindrical body 7 and pipes 8 arranged therein, in which there are movable burners 9. The burners are located concentrically relative to the raw nozzle 2. The tubes 8 have longitudinal

slits inside housing 7 for air passage.

The burner consists of a conical perforated bowl 10 with openings for the passage of air, placed along a quantity constituting a cone, and a pipe with a nozzle 11 mounted on the top of the bowl cone. The nozzle is provided with holes for the passage of fuel, the axes of which are parallel, forming a cone. For gaseous fuel applications, the nozzle pipe is made hollow, and for liquid fuel, a two-stage diffuser is installed in the nozzle pipe.

The two-stage atomizer consists of a pipe 12 for supplying fuel, an atomizer 13 and a chamber 14 for mixing liquid fuel with air.

The reactor operates as follows. .

Pre-air enters the burner devices 9 through the casing 7 of the air chamber and exits the holes in the perforated conical bowl. Gaseous fuel or an air / fuel mixture is jetted into the resulting vortex zones if liquid fuel is used. Pre-liquid fuel is mixed in a two-stage spray.

The hydrocarbon feed from nozzle 2 is directed to nozzle 4, where it is mixed with the products of complete combustion of the fuel. Through the feed nozzles 6, the mixing nozzle is supplied radially with hydrocarbon feedstock, which is sprayed with a stream of products of complete combustion of fuel.

The mixture of products of complete combustion of fuel and hydrocarbon feedstock from nozzle 4 enters the reaction chamber 5, where soot is formed. uffffoe mot aflu gas
