Poisonous and pernicious gas treatment device

Abstract

The invention discloses a poisonous and pernicious gas treatment device, and belongs to the technical field of poisonous and pernicious gas treatment equipment. The poisonous and pernicious gas treatment device is characterized in that the poisonous and pernicious gas treatment device comprises an air supply fan, an air mixing valve, a coal feeding scale (12), a pulverized coal fan (13) and a rotary kiln (15); an air outlet of an inlet pipe (18) communicates with an air inlet of a combustor (14) of the rotary kiln (15) after being connected with the air supply fan in series; the air mixing valve communicates with an air inlet of the air supply fan; an air inlet of the coal feeding scale (12) communicates with an air outlet of the pulverized coal fan (13); and a coal outlet of the coal feeding scale (12) communicates with a coal inlet of the combustor (14). The air supply fan of the poisonous and pernicious gas treatment device can guarantee the negative micro-pressure of the inlet pipe, and thus the phenomenon that poisonous and pernicious gases are exposed outwards to pollute the environment is avoided. The air mixing valve can add air into the air supply fan in time, the production technology of cement clinker cannot be influenced or destroyed, and the poisonous and pernicious gases can be treated thoroughly.

Description

technical field [0001] A toxic and harmful gas disposal device belongs to the technical field of toxic and harmful gas processing equipment. Background technique [0002] With the guidance of the national environmental protection policy and the gradual improvement of the co-processing technology of various wastes in cement kilns, the work of co-processing wastes in cement kilns is gradually carried out in cement enterprises. Due to urban domestic waste, water treatment sludge, polluted soil, Biological breeding waste, chemical waste, hazardous waste, industrial waste and other wastes may produce toxic and harmful gases with various odors or odors. Generally, airtight measures are required for storage and transportation, and storage facilities need to be operated under negative pressure. The gas needs to be treated before it can be released into the atmosphere. [0003] With the tightening of national environmental protection policies and the strengthening of environmental p...

AI Technical Summary

Problems solved by technology

[0003] With the tightening of national environmental protection policies and the strengthening of environmental protection management, some small production and processing enterprises that are prone to odor and odor gas escape have encountered production difficulties, such as furniture, mechanical parts, small leather processing, toys and clothing, and small handicrafts. , Daily chemicals, etc. Since most of these enterprises are produced by manual orders, it is very difficult to install special gas treatment devices due to technical and financial constraints.
