Description
Technical field
The present invention relates to a kind of exhaust treatment system, particularly relate to a kind of industrial waste gas treatment system and processing method.
Background technology
At present, in the problem solving industrial waste gas environmental pollution, substantially adopt and process with the following method:
Electric fishing method: be utilize deleterious particle in high-pressure electrostatic trap exhaust or tar;
Washing method: be utilize water or other liquid to absorb harmful components in waste gas or dissolve;
Absorption method: be utilize the solid dielectric of porous or chemicals one or more components in gas to be gathered or condensing on surface, reach separation object;
Filtration method: mainly by cloth bag, the dust in waste gas is gathered dust process.
Although above-mentioned various method plays an important role in current gas purification, but these methods also also exist its unsurmountable disadvantage: electric fishing method is in use for some time because attachment accumulation efficiency reduces, and the cleaning of attachment is also pretty troublesome, especially tar class, it is difficult cleaning not only, and the material after cleaning also not easily processes, secondary pollution can be caused, internal core segment will be changed after electric trapper loses effect, equipment investment cost is increased, electric fishing method is in addition relatively stricter to the temperature requirement of waste gas, and the scope of application is restricted; Washing method is except needing to consume except a large amount of water or other chemical solution, and also will carry out purified treatment to the liquid after use, cost is higher, also easily causes secondary pollution; The absorption method of current use is mainly filtered the waste gas containing particle or drop, also can absorb a certain amount of smell simultaneously, but it is not high to subparticle absorptivity, restriction due to adsorption plant structure there will be unstable, the uneven phenomenon of filter gas, in addition due to the restriction by cloth and deashing, it is made in use to create significant limitation; Bag filter method is mainly used in ash disposal, and the waste gas that it can not be used for containing adhesion and band pungent road processes.
Due to the disadvantage existing for above-mentioned various methods, so simple these methods that utilize can not meet more and more stricter purification requirement.The method of therefore how to be improved, improve or to seek to upgrade on the basis of previous methods has become the problem that this area more and more receives publicity.
Summary of the invention
The present invention is exactly the technical problem existed to solve above-mentioned various waste gas processing method, and a kind of industrial waste gas treatment system provided and processing method, it requires not strict to the EGT of required purification, not by the impact of solid particle absorption material cloth, harmful components in gas can by uniform adsorption and filtration, gas after process can directly discharge, and treatment effect is good.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
Industrial waste gas processing method, industrial waste gas is introduced in the absorber being provided with absorption material and carries out adsorption filtration, by the gas after adsorption filtration after the gas outlet of absorber enters mixer for gas and powder by pipeline, by the further mixing and absorption of the powder sprayed, gas after mixing and absorption enters sack cleaner via pipeline to carry out filtering again and absorption, this time after filtration with absorption after gas directly introduced chimney by air-introduced machine and discharge.
The absorption material of filling in above-mentioned absorber is undertaken circulating and regularly replacing by circulation discharge particulate material device after a procedure.
The absorption powder that above-mentioned mixer for gas and powder domestic demand is sprayed, absorption powder carries out continuous circulation supply and periodic replacement by continuous circulation discharge powder device.
Industrial waste gas treatment system, its structure is as follows: absorber is provided with industrial waste gas entrance, the gas outlet of absorber is connected with mixer for gas and powder by pipeline, the gas outlet of mixer for gas and powder is connected by pipeline with the sack cleaner with air-introduced machine, and the gas vent of sack cleaner is connected with chimney by pipeline.
Absorption material inlet on above-mentioned absorber is all connected by pipeline with circulation discharge particulate material device with absorption waste outlet, and circulation discharge particulate material device is provided with a feeding mouth and a waste outlet.
The powder entrance of above-mentioned mixer for gas and powder is connected with continuous circulation discharge powder device by pipeline, and the feeding mouth of continuous circulation discharge powder device is two, and one is virgin material import, and another is connected with the powder outlet of sack cleaner.
Owing to adopting technique scheme, tool of the present invention is had the following advantages and effect:
1, the EGT of required purification is required strictly, except high temperature, without the need to arranging cooling and heating device, investment reduction when general.
2, because of not by the restriction of filtrate cloth state, the harmful components in absorber in industrial waste gas can by uniform adsorption and filtration, so compensate for the deficiency of current purge equipment.
3, all materials for adsorbing can regularly replace by Reusability, and the method not only improves the operating efficiency of system but also saves manpower, power and material resources.
4, native system is originated for the material adsorbed and is drawn materials extensively, is easy to selected.
5, native system power consumption is low, non-secondary pollution.
6, three purifications of system in the present invention, filter adsorption efficiency higher than existing cleaning equipment.
7, all devices structure simple operating period of the present invention is long, which overcome current all waste gases purification manufacturing equipment cost high, consume energy high, the complicated or unendurable defect of flow process.
