Carbon roasting furnace smoke pollutant heat storage incineration furnace and treatment method thereof

Abstract

The invention relates to the technical field of carbon roasting furnace smoke pollutant treatment, in particular to a carbon roasting furnace smoke pollutant heat storage incineration furnace and a treatment method thereof. The carbon roasting furnace smoke pollutant heat storage incineration furnace comprises a combustion chamber, heat storage chambers, a reversing system, a reverse burning system and a purging system; two sets of heat storage chambers are provided; each set of heat storage chambers comprises more than three heat storage chambers; the two sets of heat storage chambers are symmetrically arranged on the two sides of the incineration furnace; the heat storage chambers directly communicate with the combustion chamber; the two sets of heat storage chambers communicate by the reversing system; and the heat storage chambers communicate with an exhaust pipe through the reverse burning system. A heat storage technology is applied to the carbon roasting furnace smoke pollutanttreatment, and comprises heat storage, combustion oxygenolysis, combustion heat relief, purging and reverse burning; smooth incineration of carbon roasting furnace smoke pollutants can be guaranteed;the smoke emission accords with the air pollution release standard; the heat storage energy saving characteristic is achieved; the energy consumption is reduced; and the treatment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of carbon roaster flue gas pollutant treatment, in particular to a carbon roaster flue gas pollutant regenerative incinerator and a treatment method thereof. Background technique [0002] The production process of the carbon industry will produce a large amount of asphalt-containing fume, which is generally mixed with a certain concentration of smoke and asphalt fume, which is brown or black and has a strong stimulating effect. The benzo-a-pyrene contained in the flue gas is recognized as the world's three major carcinogens (Aspergillus flavus, benzo-a-pyrene, and nitrite). At present, the carbon industry mainly uses the electric capture method to treat the asphalt fume exhaust gas. The treatment efficiency of the electric tar capture device is about 85%, which can remove most of the harmful components in the flue gas, but cannot fundamentally solve the problem of emission compliance; at the same time It al...

AI Technical Summary

Problems solved by technology

At present, the carbon industry mainly uses the electric capture method to treat the asphalt fume exhaust gas. The treatment efficiency of the electric tar capture device is about 85%, which can remove most of the harmful components in the flue gas, but cannot fundamentally solve the problem of emission compliance; at the same time It also produces a large amount of solid and liquid waste; the electric capture method still has the risk of fire and explosion in practical application; and the bitumen-containing flue gas itself has a certain calorific value, and this part of energy is also wasted

In addition to the electric capture method, the carbon industry also uses the direct incineration method to treat the asphalt fume waste gas. The conventional incinerator is used to burn natural gas with a conventional burner to heat the furnace to 800 degrees to incinerate the pollutant flue gas. Although the incineration effect is up to standard , but the consumption of natural gas is large and the cost is high

[0003] The application of regenerative technology in industrial furnaces in the domestic iron and steel industry has been greatly developed. Domestic regenerative technology has been developed earlier and its use is very mature; however, regenerative technology is only used to reduce energy consumption in the process of heating materials, and Not applied to the treatment of pollutants in the carbon industry
