Large carbon powder type calcining equipment

Abstract

The invention discloses large carbon powder type calcining equipment. The large carbon powder type calcining equipment is characterized by comprising a guide body, a premixing chamber, a shunt instrument, a shunt port, combustion assisting gas, a fuel chamber and a valve, wherein the premixing chamber is a cylindrical structure opened at two ends; the premixing chamber is divided into 4-6 guide chambers by the guide body of the premixing chamber; a guide plate is arranged on the guide body, and adopts a straight plate structure or a spiral plate structure; a combined pipe body is inserted in the premixing chamber; and the shunt instrument with a cone structure is arranged in an outlet area of the combined pipe body. The large carbon powder type calcining equipment has the advantages of optimizing the ignition and lime kiln work starting operation, reducing the labor intensity, shortening the solid fuel ignition and lime kiln work starting time and saving the ignition cost.

Description

technical field [0001] The invention belongs to the technical field of combustion equipment, and relates to an ignition burner, in particular to a pulverized coal igniter, and now particularly provides a large carbon powder type calcination equipment. Background technique [0002] Existing calcination equipment mainly consists of beam type lime kiln, sleeve type lime kiln and co-current double-chamber lime kiln, etc. The fuel used for calcination is mainly solid fuels such as gaseous fuel and coal powder and coke powder. The beam type lime kiln for pulverized coal mostly adopts the above ignition method. When the temperature in the kiln is high, the pulverized coal can be fed directly for re-combustion if the kiln is stopped for a short time. The kiln is re-ignited. Each time the kiln is re-ignited, a large amount of waste needs to be removed, which wastes a lot of manpower, material resources and materials. The same problem exists in the intermittently operated pulverized c...

[0002] Existing calcination equipment mainly consists of beam type lime kiln, sleeve type lime kiln and co-current double-chamber lime kiln, etc. The fuel used for calcination is mainly solid fuels such as gaseous fuel and coal powder and coke powder. The beam type lime kiln for pulverized coal mostly adopts the above ignition method. When the temperature in the kiln is high, the pulverized coal can be fed directly for re-combustion if the kiln is stopped for a short time. The kiln is re-ignited. Each time the kiln is re-ignited, a large amount of waste needs to be removed, which wastes a lot of manpower, material resources and materials. The same problem exists in the intermittently operated pulverized coal-fired hot blast stove. Every time it is restarted, it is necessary to ignite the primer with firewood. Burning pulverized coal is time-consuming and labor-intensive, and increases costs
