High-temperature smashing reaction device for chemical industry fuels

Abstract

The invention discloses a high-temperature smashing reaction device for chemical industry fuels. The high-temperature smashing reaction device for the chemical industry fuels comprises an outer barrel, wherein the outer barrel is a cylinder; a hollow reaction cavity is arranged in the outer barrel; a material inlet is formed in the top part of the right side of the outer barrel; a smashing device is arranged above the material inlet; a coke outlet is formed in the bottom part of the left side of the outer barrel; the material inlet and the coke outlet are both communicated with the inner part of the outer barrel. According to the device, a plurality of high-temperature gas conveying pipes are embedded in the outer barrel along a circumferential direction, and an auger shaft is arranged in the reaction cavity, so that bituminous coal is forward conveyed in the reaction cavity through the auger shaft, and is squeezed and fractured through auger blades and an inner wall of the outer barrel at the same time; high-temperature gas uniformly sent out through air nozzles on the high-temperature gas conveying pipes is mixed uniformly and is controlled at constant temperature, so that the pyrolysis efficiency is improved.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a high-temperature pulverizing reaction device for chemical industrial fuel. Background technique [0002] The chemical production process needs to use a lot of fuel, the most common fuel is coal, among which bituminous coal has a high storage capacity in my country's geology, but due to the high content of impurities in bituminous coal, a large amount of smoke is produced during combustion, and the smoke contains a lot of Pollution gases cause great harm to the environment. Therefore, the country has gradually reduced the use of bituminous coal as fuel. However, the gas, tar and coke produced by bituminous coal after pyrolysis are the raw materials and fuel sources that are widely needed in industrial production. , as high-metamorphic coals are used less and less, the optimal utilization of low-quality coal is becoming more and more important. Due to the high viscosity of bitumino...

[0002] The chemical production process needs to use a lot of fuel, the most common fuel is coal, among which bituminous coal has a high storage capacity in my country's geology, but due to the high content of impurities in bituminous coal, a large amount of smoke is produced during combustion, and the smoke contains a lot of Pollution gases cause great harm to the environment. Therefore, the country has gradually reduced the use of bituminous coal as fuel. However, the gas, tar and coke produced by bituminous coal after pyrolysis are the raw materials and fuel sources that are widely needed in industrial production. , as high-metamorphic coals are used less and less, the optimal utilization of low-quality coal is becoming more and more important. Due to the high viscosity of bituminous coal, it is often difficult for high-temperature air to fully mix with bituminous coal during pyrolysis, resulting in a low pyrolysis rate. situation happened
