Description

A kind of exhaust gas purification and treatment device
Technical field
The utility model relates to technical field of waste gas treatment, relates in particular to a kind of exhaust gas purification and treatment device.
Background technology
The waste gas that exhaust-gas treatment refers to produce at industrial site, factory floor is externally carrying out preliminary treatment before the discharging, to reach the external emission standards of national waste gas.General exhaust-gas treatment comprises aspects such as organic exhaust-gas treatment, dust exhaust-gas treatment, soda acid exhaust-gas treatment, peculiar smell exhaust-gas treatment and air disinfection sterilizing and purifying.
Common waste gas processing method has active carbon adsorption, Production by Catalytic Combustion Process, chemical washing method, acid-base neutralization method, plasma method, photocatalytic oxidation etc.For example, the processing method of organic exhaust gas has the condensation absorption method, absorption method, and Production by Catalytic Combustion Process, spray process etc., inorganic waste gases mostly pass through water-soluble, acid-base neutralization, methods such as strong oxidation are handled.In practical operation, can be with two or more methods in conjunction with handling waste gas.
The waste gas that produces with the rubber for tire industry is example.The peculiar smell waste gas that the banbury of rubber for tire industry, vulcanizer produce in process of production can cause very big influence to on-site, external environment.Along with the raising of country to rubber enterprise factory gas discharge standard, be about to put into effect new national standard, require relevant enterprise to handle gas, after sulfide and organic volatile are up to standard, can discharge.At present the gas with foreign flavor that produces of process of factory production adopts direct discharging modes, and along with the output of tire constantly increases, a large amount of gas with foreign flavor can produce the environment of periphery and have a strong impact on.
At the particularity of rubber industry exhaust gas constituents, higher because of its VOCs and element sulphur content, adopt thoroughly all organic principles in the purifying exhaust air of single chemical absorption method, therefore, often adopt the waste gas processing method of several different methods associating.Common compound mode has: chemical absorbing+active carbon adsorption; Plasma+photocatalytic oxidation; Chemical absorbing+photocatalytic method; Chemical absorbing+plasma method etc.
It is better that active carbon adsorption is handled the organic exhaust gas effect, but because it exists resistance big, energy consumption is big, and material all drawbacks such as reaches capacity easily and limits its use; Though the processing method of existing plasma or chemical absorbing and catalytic oxidation associating can solve the big problem of equipment self resistance, has drawback equally.Plasma and photochemical catalytic oxidation combined techniques principle are to make harmful components cracking in the waste gas by high electric energy, thereby reach the purification purpose, so this method will be very big if will handle atm number waste gas consumed power.
CN101366966A relates to a kind of method and device of foul gas purified treatment, by optimizing integrated ultraviolet catalytic and ozonation technology, with the processing of the foul gas that adapts to variable concentrations and composition.In this invention, ultraviolet catalytic and ozone oxidation are carried out in same reactor.
The waste gas processing method of existing and plasma or photocatalysis associating is to adopt waste gas directly to enter plasma or light to facilitate in the reative cell and interact with it, and waste gas directly contacts with reactor.Because rubber for tire industry exhaust gas constituents particularity, it is many to contain volatile organic matter (oils), cause methods such as catalytic oxidation and plasma after operation a period of time, cover oily cumulative on the generator, cause catalysqt deactivation or light to pass plasma generator and the treatment effect of equipment is reduced greatly, this is the serious problems that present rubber tyre industry waste gas treatment equipment exists.
At present, most of waste gas treatment equipments adopt chemistry spray absorption process.This method is remarkable for handling the higher industrial waste gas effect of element sulphur content, but the method water loss is big, and the secondary waste water pollution problem is serious.
The utility model content
The purpose of this utility model is at prior art problems, proposes the exhaust gas purification and treatment device of a kind of economic and practical, energy-conserving and environment-protective, advanced technology, makes exhaust-gas treatment reach cleaner production and environment protection emission requirement.Especially, the utility model simultaneously, is saved operating cost to a great extent to refining glue and vulcanizing workshop section's exhaust gas discharged and can more effectively handle, and realizes social benefit, economic benefit, the tripartite unification of environmental benefit.
For reaching this purpose, the utility model by the following technical solutions:
The utility model provides a kind of method for purifying and processing waste gas, and described method employing chemical absorption method is combined with the superoxide radical oxidizing process waste gas is carried out purified treatment; Described superoxide radical oxidizing process generates superoxide radical and the off-gas oxidizing decomposition is separately carried out.
