Description
Technical field
The present invention relates to field of environment protection equipment more particularly to a kind of recycling of composite adsorption microwave or pyrolysis processing organic exhaust gas
Method.
Background technique
Air pollution control is one of major domain of environmental protection, and volatile organic contaminant (VOCS) is to generate haze
One of main polluted factors, seriously affect the health of the mankind, greatly influence people's lives quality.Currently, VOCS
The pollution of environment has been received significant attention.
The currently used for example direct combustion method of VOC processing technique is only applicable to high-concentration organic waste gas processing；Catalysis burning
There are security risks for method；RTO method equipment investment is too big；Not only treatment effeciency is not high and safety there are explosive for plasma technology
Hidden danger；The treatment effeciency of ultraviolet light solution is not high.Meanwhile above method organic resources cannot recycle.Activated carbon adsorption
It is wide that method handles organic matter range, and can Resource recovery, but the investment of organic matter reclaimer is big, small-sized waste gas treatment engineering without
Recycling device is arranged in method, moreover, active carbon is used as dangerous solidification disposal of waste without regeneration, it is economically unbearable.
In conclusion there is respective defect in practical applications in above method.It is a kind of new it is therefore desirable to develop
, the VOCs treatment technology for being able to solve above-mentioned technical problem.
In addition, either coal-fired flue gas desulfurization and denitration demercuration or incineration treatment of garbage, cement firing, various industry kilns
The exhaust gas generated in furnace and industrial production, the burning of biomass fuel, it is various contain VOCSSolid particulate matter present in exhaust gas, gas
Colloidal sol, greasy dirt, the paint dirts such as slag and salt all can environmental protection equipment to exhaust-gas treatment and corresponding catalyst will cause it is serious
Pollution, to influence the treatment effeciency of environmental protection equipment.
In order to solve this problem, it is necessary to exhaust gas is pre-processed, is had much for the preconditioning technique of exhaust gas at present,
But apparent defect is individually present.For example, subsequent main body treatment process can be made by carrying out water spray processing to exhaust gas at present
At negatively influencing；Using fixed strainer pretreatment, strainer is easy to be blocked up by dirt, and the short time increases the resistance of air-flow, it is necessary to shut down more
It changes.
To sum up, in the prior art, there is respective defect for the various preconditioning techniques of exhaust gas, practical application is inadequate
It is ideal, it is therefore necessary to develop a kind of preconditioning technique that is new, being able to solve above-mentioned technical problem.
Summary of the invention
In order to solve the above-mentioned technical problems, the present invention provides a kind of recycling of composite adsorption microwave or pyrolysis processing organic wastes
The method of gas, the present invention are applicable not only to low concentration Wind Volume VOCs treatment and are also applied for high-concentration organic waste gas processing,
In being more suitable for, small-scale emission-control equipment.Enrichment can be adsorbed first for low-concentration organic exhaust gas, pyrolysis is desorbed again；For
High-concentration organic waste gas is adsorbable, desorption, is pyrolyzed while carrying out, to use lowest energy consumption to obtain peak efficiency.The present invention uses
Active carbon and zeolite compartment arrangement, improve the efficiency of microwave, avoid existing single use active carbon because active carbon is to micro-
The absorption of wave and the shortcomings that influence the radiation depth of microwave.
The specific technical proposal of the invention is: a kind of method of composite adsorption microwave recycling or pyrolysis processing organic exhaust gas,
It is divided into both of which according to pollutant concentration:
Mode one: being most suitable for the exhaust gas of low concentration the following steps are included:
1) it pre-processes: pre-filtering being carried out with pretreatment unit to exhaust gas, removes large granular impurity and colloidal substance；
2) absorption enrichment: pretreated exhaust gas is passed through in microwave heating appts, is filled out using the interval in microwave heating appts
Ceramic tube filled with active carbon layer and zeolite layer in exhaust gas organic pollutant or salinity adsorb；When ceramic tube is adsorbed onto
After to a certain degree, stop logical exhaust gas, the microwave heating appts that another parallel connection is led in exhaust gas conversion are continued to adsorb, and so on；
3) it empties or post-processes: to step 2 treated exhaust gas carries out emptying or further work-up；
4) desorption by microwave or pyrolysis: carrying out microwave heating to the ceramic tube for stopping logical exhaust gas in step 2, make pollutant be desorbed or
It decomposes；
5) cooling emptying or recycling: the tail gas generated to step 4) cools down, and carries out emptying to gas after cooling or into one
Step post-processing, recycles the resulting organic matter of cooling；
6) secondary desorption: hot water, desorption liquid or hot-air are led to the ceramic tube after microwave treatment, further desorption remains in ceramics
The pollutants such as the salt in pipe.
Mode two: it is most suitable for the exhaust gas of high concentration, comprising the following steps:
1) it pre-processes: pre-filtering being carried out with pretreatment unit to exhaust gas, removes large granular impurity and colloidal substance；
2) microwave decomposition in absorption: pretreated exhaust gas is passed through in microwave heating appts, using in microwave heating appts
Ceramic tube of the interval filled with active carbon layer and zeolite layer in exhaust gas organic pollutant and/or salinity adsorb；Together
When microwave-heating is carried out to the substance that is adsorbed；
3) cooling: to step 2, treated that exhaust gas cools down；
4) it empties or post-processes: emptying or further work-up are carried out to exhaust gas after cooling；
5) secondary desorption: hot water, hot steam, hot-air or acidic aqueous solution are led to the ceramic tube after microwave treatment, further taken off
The pollutants such as the attached salt for remaining in ceramic tube.
Different processing modes may be selected according to the different situations of exhaust gas in the present invention, flexible and changeable, is widely portable to not
With the organic exhaust gas in source.
The present invention is in ceramic tube using interval filling active carbon and zeolite.The present inventor has found in the course of the research, such as
Fruit solely fills active carbon as adsorbent, and will lead to microwave can only enter activated carbon surface, and be difficult to penetrate in active carbon
Portion, thus it is not high to the parsing and decomposition efficiency of the organic matter adsorbed in active carbon.And if it is single use zeolite, parsing and
The energy consumption of decomposing organic matter is higher.After extensive testing, discovery microwave can penetrate zeolite, therefore be spaced setting active carbon
And microwave, it can be ensured that microwave is in low energy consumption, efficiently desorption and decomposing organic matter, activated carbon of sorbent and zeolite energy repeated regeneration
It utilizes, cost is greatly reduced.
Preferably, the diameter of the ceramic tube is 50-100mm in step 2；Absorption of the exhaust gas in ceramic tube stops
Time is desorbed, is decomposed (or recycling), regeneration after can running a few hours to several weeks according to organic concentration difference in exhaust gas.It is micro-
Wave desorption, resolving time are 1-5 seconds.
Team of the present invention finds after study, if the diameter of ceramic tube is excessive, large area adsorbent be easy to cause air-flow
Uneven or short circuit and cause treatment effeciency low.After extensive testing, microwave heating appts of the invention use minor diameter
Ceramic pipe reactor, gas is more evenly distributed, and can avoid above-mentioned technical problem.
Preferably, every layer of active carbon layer with a thickness of 25-35mm, every layer of zeolite layer with a thickness of 5-15mm.
By active carbon layer and the design of zeolite layer thickness behind above-mentioned section, microwave can be made effectively to penetrate, obtained highest de-
