Brake shoe workshop curing furnace waste gas treating system and method

Abstract

The invention discloses a brake shoe workshop curing furnace waste gas treating system and a brake shoe workshop curing furnace waste gas treating method. The system comprises a diffused smoke treating system and a waste gas treating system, wherein the diffused smoke treating system comprises a first gas flue which is respectively connected with diffused smoke outlets of a first curing furnace door smoke hood and a second curing furnace sealing chamber; the first gas flue is sequentially connected with a first centrifugal fan and an outer chimney; the waste gas treating system comprises a second gas flue which is respectively connected with waste gas outlets of a first curing furnace and a second curing furnace; the second gas flue is sequentially connected with a second centrifugal fan, a combustion chamber, a third centrifugal fan and the outer chimney. The system and the method have the beneficial effects that combustible pollutants, suspended carbon granules and smog-shaped organics in curing furnace waste gas can be burnt off, and odor gas can be completely oxidized; the system and the method have the advantages of obvious peculiar smell removing effect, high deodorization efficiency, convenient technique operation, stable operation performance and the like; a work field environment and the surrounding environment are greatly improved; the requirement of national environment protection is met.

Description

technical field [0001] The invention relates to a waste gas treatment system and method of a curing furnace in a brake shoe workshop. Background technique [0002] The brake shoe workshop mainly produces HGM-B high-friction synthetic brake shoes, HGM-D high-friction synthetic brake shoes and 4-2W low-friction synthetic brake shoes. The main components of the waste gas released during the curing process are: sulfur dioxide, ammonia , formaldehyde, hydrogen sulfide, phenol, benzene, nitrogen dioxide, CS2, aniline, phenol, CO2 and other odorous and harmful gases, these gases will have a greater impact on the surrounding environment and the health of employees. [0003] There are many existing exhaust gas treatment methods, such as: solution absorption method, adsorption method, catalytic combustion method, biodegradation method, etc., but each has its advantages and disadvantages. It is not that the deodorization efficiency is low, the later maintenance is inconvenient, and sec...

[0003] There are many existing exhaust gas treatment methods, such as: solution absorption method, adsorption method, catalytic combustion method, biodegradation method, etc., but each has its advantages and disadvantages. It is not that the deodorization efficiency is low, the later maintenance is inconvenient, and secondary pollution is formed. The later operation cost is high, and the environmental protection standard cannot be met
