Description
Technical field
The present invention is directed to the production process of rubber tyre in chemical industry, especially rubber VOCs waste gas cyclone adsorbing-sweet smell
Pause the degraded complete method and apparatus of coupling processing.
Background technology
The manufacturing of rubber tyre is the main part of rubber industry, accounts for the 90% of rubber industry total industrial output value
More than.Rubber tyre can produce large quantity of exhaust gas, and complicated components during the manufacturing.According to American National Environmental Protection Administration
Establishment《Air pollutant emission coefficient collects》, the rubber tyre waste gas discharge factor is up to 63 kinds, and its primary discharge factor is
The materials such as particulate matter, NMHC, ammonia, styrene, hydrogen sulfide, dimethylbenzene, methyl mercaptan, methyl sulfide.Except particulate matter, ammonia with
And beyond hydrogen sulfide, other primary discharge factors can be classified as the category of volatile organic matter (VOCs).VOCs can not only make
It is into atmosphere pollution and huge to human health risk, people can be allowed to feel headache, Nausea and vomiting, limbs fatigue, or even go out
Now twitch and go into a coma.
The features such as rubber tyre VOCs waste gas has low, large-minded concentration, complicated component, now VOCs waste gas pollution control and treatments technology
It is divided into physiochemical mutagens technology and the major class of chemical destruction technology two.Physiochemical mutagens technology includes compression condensation, absorption, absorption etc., changes
Destruction technology is including (catalysis) burning, (catalysis) oxidation, catalyzed conversion, bioconversion etc..During most of business processes VOCs
All use absorption method or combustion method, or two kinds of methods being combined.
Absorption method is using porous sorbent treatment fluid mixture, so that one of which or several components are concentrated in
Adsorbent surface, the adsorbent for generally using is based on activated carbon.Adsorption plant can be divided into fixed bed, fluid bed and moving bed and inhale
Adsorption device.Abroad in Recent Years and China's Taiwan fluid bed and the development of moving bed adsorbent equipment comparatively fast, should in Practical Project
With extensive；The fluidised bed adsorption system footprint area of Japanese Wu Yu companies exploitation is small, and VOCs clearances are up to more than 95%.
Lillo-Rodenas etc. selects the activated carbon of different structure, and absorption research is carried out to Low Concentration of Benzene and toluene, finds to be less than
Dominating role is played in VOCs absorption of the micropore of 0.7nm to low concentration.Hsieh etc. have studied various VOCs suctions on the activated carbon
It is attached to be distributed, it is indicated that size, structure, polarity of VOCs molecules etc. can influence absorption behavior.However, due to rubber industry waste gas
Discharge capacity is big, VOCs complicated components, and big, adsorbent high cost, adsorbent reactivation are difficult, be also easy to produce two to cause adsorption plant to take up an area
The problems such as secondary pollution.
On the other hand, the technology such as VOCs conversions or thorough burning, oxidation, catalyzed conversion destroyed is capable of achieving in rubber industry
Also had a wide range of applications in VOCs controls.VOCs can be converted into harmless hydro carbons, CO2, water etc. by these technologies.In recent years,
Heat storage is increased on the basis of flame combustion as thermal energy storage and reuse means, has developed heat accumulating type flame combustion skill
Art (RTO).RTO key problem in technology is to select suitable heat storage, and reed time controll valve transfer cycle and in good time start and stop burning
Device controls reaction chamber temperature.Can reduce activation energy needed for oxidation operation using catalyst and improve reaction rate, so as to compared with
By organic matter degradation under low temperature (300~500 DEG C), it is catalyst typically to use precious metals pd, and price is costly.In recent years
Come, and new development heat accumulating type catalytic combustion technology (RCO), but above-mentioned technology has equipment complicated difficult to amplify, operate
Unstable, efficiency is low, high cost the problems such as.
Therefore, this area being capable of low cost, stable operation, while not producing the rubber of secondary pollution in the urgent need to developing one kind
The glue VOCs waste gas cyclone adsorbing-Fenton degraded complete method and apparatus of coupling processing.
