Description
Technical field
The utility model relates to industrial equipment efflux gas processing technology field, particularly relates to a kind of gas cleaning plant in the fields such as coating, copper-clad plate, waste incineration.
Background technology
In coating, the final all kinds of waste gas (comprise residual raw materials, high-temp waste gas etc. that intermediate, burning produce afterwards) produced generally are processed by combustion method in copper-clad plate industry; to reach country and local discharge standard requirement; but; more and more pay attention to along with to environmental protection work; add that the concentration that the odor threshold of people often requires than country and local discharge standard is much lower; odor threshold refers to that people can smell the least concentration of certain taste, and the odor threshold of people is roughly 0.03mg/m
3, reach 25mg/m in gas concentration
3shi Renhui feels to stimulate.
In current industry, in line pattern is mainly adopted to the processing mode of incinerator exhaust gas, for copper-clad plate field, in gluing process, the solvent of volatilization comprises NxOx, Sox, HxSx, NMHC, lipid small molecular weight material, benzene micromolecular material, Small Phenolic Molecule material, ethers small-molecule substance etc., these mists are after incinerator burning, containing sulfide in waste gas, the particular matters such as nitrogen oxide and multiple organic principle (being referred to as VOCs), and containing generating portion first sulphur during imperfect combustion in this gas, the pungent type gases such as A Moni (containing ammonia foul smell), though burn through incinerator, but can not process completely clean (treatment effeciency of RTO incinerator only has 95-99%).These special materials, with intense stimulus and peculiar smell stench, add low odor threshold characteristic, as easy as rolling off a log by the perception of people's sense of smell institute.
In prior art, the deodorization technique of gas has direct combustion method, Ozonation, sorption method, liquid ablution, absorption process, biological deodorization method, plasma deodorization method and catalyst oxidizing process etc.First, gas (being later the called for short process gas) temperature range produced due to incinerator is comparatively wide, and generally within the scope of 80 DEG C ~ 200 DEG C, and the exhaust temperature of the incinerator of various model is not quite similar; Secondly, the air quantity of process gas is comparatively large, from 10000m
3/ h ~ 12000m
3/ h is different, and it is higher that peculiar smell removes requirement, processed gas with foreign flavor is difficult to remove with single method and meets not by the requirement of people's sense of smell institute perception, therefore, the conventional method such as Ozonation, sorption method, liquid ablution and plasma method is all unsuitable for carrying out deodorization to incinerator exhaust gas.Meanwhile, combustion method is not remarkable for effect that is acid or inorganic waste gases, and detect the waste gas after burning, Main Ingredients and Appearance is sulfur dioxide, nitrogen oxide and part organic principle, has strong impulse smell.In addition, organic principle in waste gas has low olfact characteristic, organic substance is not fully oxidized when burning, produce secondary pollution, directly the cost of combustion method is quite high again again, so traditional processing method all can not reach actual demand in many-sides such as cost, security, treatment effeciencies.
