Abstract
The invention discloses a novel waste rubber desulphurization waste gas three-stage energy-saving green treatment process method; waste gas generated after waste rubber desulfurization is dedusted by a front-section dedusting device and subjected to gas cooling treatment through two-stage heat exchange and then enters a gas buffer chamber, then the waste gas is sent into a low-temperature plasma reactor by an induced draft fan and is subjected to one-stage low-temperature plasma action, a lot of macromolecular organic pollutants are converted into small-molecular substances, and next in a chemical oxidation absorption tower, the waste gas after front-section oxidative decomposition and a little amount of undecomposed waste gas are subjected to two-stage chemical oxidation reduction absorption treatment. With adopting of a combined treatment process of a traditional process and a high-tech process, the method has the characteristics of low energy consumption, simple and convenient control, small land occupied area, easy and convenient maintenance, stable and safe running and the like, the whole treatment process has no need of high investment in equipment and handling costs and can far reach discharge standards, has no secondary pollution production, and has quite good application prospects in the field of waste tire waste gas treatment.
Description
Technical field
The invention belongs to technical field of waste gas treatment, relate to a kind of energy-conservation green treatment process method of novel waste and old devulcanization of rubber waste gas three grades.
Background technology
Future gets more and more along with automobile use amount, and the destruction of a large amount of junked tires to environment produced is increasing, and therefore junked tire recycles and is subject to domestic and international extensive concern.Current domestic junked tire recycles mainly produces reclaimed rubber, a certain amount of pollutant can be produced unavoidably in its production process, wherein the process of waste gas is relatively difficult, its processing method is a lot, as the charcoal absorption method of purification, chemical agent absorption process, catalytic purification method, biological clarification, plasma purification method etc., but mostly there is certain defect, as low in treatment effeciency, energy consumption is higher, also exist selective to process gas, also likely produces secondary pollution etc. simultaneously.Therefore; present stage is by researching and developing Waste rubber desulfurization waste gas combined treatment process; in conjunction with two kinds or two or more waste gas treatment process advantage separately; segment processing is carried out to waste gas; finally reach the high and novel process technique of non-secondary pollution of low energy consumption, high purification efficiency, automaticity, well realize environmental protection and economic development doulbe-sides' victory
Summary of the invention
The object of the present invention is to provide a kind of novel, energy-conservation, green Waste rubber desulfurization waste gas tertiary treatment process.
The present invention is achieved through the following technical solutions:
A kind of novel waste and old devulcanization of rubber waste gas three grades of energy-conservation green treatment process methods, its processing method comprises the steps:
A. the waste gas produced after Waste rubber desulfurization exchanges through the dedusting of leading portion cleaner and two levels of thermal and carries out entering in gas buffer room after gas cooling processes; Wherein solid matter recycling after dedusting, the cooling water after heat exchange is for heating and other domestic waters;
B. change a large amount of large molecular organic pollutants in waste gas into small-molecule substance by air-introduced machine by carrying out the effect of one-level low-temperature plasma in the waste gas feeding reaction of low temperature plasma device after step A preliminary treatment, various reaction conversion ratio is all more than 98%;
C. a small amount of pollutant of residue after the process of low temperature plasma initial breakdown and the small-molecule substance changed into enter in chemical oxidation absorption tower and impel it to reach spray pattern by two-layer Full-automatic circulation spray system spray-absorption liquid, ensure the contact area that itself and waste gas are maximum, further secondary chemical redox fully absorbs process;
D. finally enter three grades of Treatment by Photocatalysis Oxidation, the Small molecular or the permineralization that untreated a small amount of waste gas completely are thoroughly converted into odorless under photocatalyst works in coordination with decomposition oxidation generate H
2o and CO
2, finally by rearmounted blower fan, the cleaned air after process is carried out high-altitude from exhaust chimney and drains into air.
Described absorbing liquid is made up of the raw material of following mass percent: 7-10%NaOH, 12-20%NaClO, and surplus is water.
Beneficial effect of the present invention:
1. this waste gas treatment process have employed the combined treatment process and low-temperature plasma degradation+green associated treatment technique of chemical oxidation absorption+photocatalytic oxidation degradation three grades that traditional handicraft and high-tech technique combines, give full play to three kinds of waste gas processing method advantages and Low Temperature Plasma Treating energy consumption low, be swift in response, vapour lock is little, high-efficient purification deodorizing, non-secondary pollution and be applicable to Wind Volume exhaust-gas treatment, chemical oxidation absorbs process not only can remove water-soluble pollutant in waste gas, simultaneously also can process the particle of more than micron and purification efficiency is not high, photocatalysis oxidation method acts synergistically in conjunction with photocatalyst, waste gas can be impelled thoroughly to change into the micromolecular compound H of odorless
2o and CO
2or permineralization, is swift in response and non-secondary pollution produces, and is applicable to the pollutant that concentration for the treatment of is low.
2. these three grades of green treatment process possess energy consumption low, control easy, the feature such as floor space is little, maintaining is easy, stable and safe in operation, whole processing procedure can reach discharge standard far away without the need to high equipment investment and processing cost, and basic non-secondary pollution produces, and possesses good application prospect in junked tire exhaust-gas treatment field.
