How does rubber industry capture the technology of off-gas treatment is challenged

In rubber industry the meeting in production produces many organic waste gas, waste gas characteristic is discharge capacity composition of big, pollution is complex and changeful. Effluvial material is contained in balata waste gas, use gentle model waste gas purifies craft relatively ideal and safety, general proposal uses desorption of activated carbon adsorption, biology to filter catharsis, condensation is absorbed wait for craft. Biology purifies craft most appropriate.

　　Waste gas pollutes a feature

In rubber industry the meeting in production produces many organic waste gas, waste gas characteristic is discharge capacity composition of big, pollution is complex and changeful. Effluvial material is contained in balata waste gas, can stay in air longer, can cause all sorts of undesirable effects. Its composition basically has these a few kinds: 1, the compound that contains sulfur: If sulfur of H2S, SO is mellow kind, sulfur aether kind; 2, dust kind: Be like carbon black; 3, chloric compound: The amine that be like acyl, indole kind; 4, hydrocarbon kind: Be like hydrocarbon of alkyl hydrocarbon, alkene, alkyne, balmy hydrocarbon; 5, oxygenous organic matter, wait like mellow, phenolic, aldehyde, ketone, organic acid. According to the regulation, these waste gas diffuse inside the workshop, those who harm a worker is healthy, pollution will be caused to surroundings again outside eduction workshop. Accordingly, environmental protection branch already asked to undertake depurative handling to this kind of waste gas, achieve pollution to control pollutant discharge standard of industry of products of standard GB-27632-2011 rubber.

　　 The technology of off-gas treatment is challenged

From the point of analysis of composition of balata waste gas, the material containing sulfur such as alcohol of aether of many vulcanization hydrogen, sulfur, sulfur is contained in its composition, when handling this type contaminant, do not apply to the only chemical industry such as plasma of smooth catalysis oxidation, low temperature art, use gentle model waste gas purifies craft relatively ideal and safety, general proposal uses desorption of activated carbon adsorption, biology to filter catharsis, condensation is absorbed wait for craft. In rubber products waste gas, contain many flue gas dust, on relevant technology design, lv of take an examination uses better pretreatment equipment system, make sure equipment of off-gas treatment back end purifies efficiency.

As a result of the character that absorbs in activated carbon adsorption, condensation, need undertakes extreme ending is handled, will tell at activated carbon, need undertakes useless, desorption is handled originallying, increase waste gas to purify cost; Absorb craft to tell at condensation, waste liquid liquid waste needs to handle, also bring waste gas to purify cost burden to the enterprise, from this clearly, biology purifies craft most appropriate.

　　 Design of off-gas treatment technology and principle

Biology purifies craft is waste gas purifies the engineering technology with relatively good technology, safety of its advantage environmental protection, pollute without 2, it is almost to environmental influence 0. In biology catharsis of drop filtration filter purifies craft form 3 kinds in, waste gas purifies a principle is to use microbial metabolic principle, the pollutant in exploiting technological equipment environment is nutrient, will realize ego breed and metabolization. When handling balata waste gas, those who need a consideration is, do the stability of environment of good technological equipment as far as possible, operating mode considers as far as possible when craft is designed, output of control waste gas is worth stability, pretreatment phase is used better remove dust except smoke equipment, will promote balata waste gas to purify efficiency and output effect, reach a nation or contaminant of local balata waste gas discharges demand.

　　Characteristic of off-gas treatment craft and advantage

Balata off-gas treatment uses biology to purify craft, can be after equipment operation is stable, need not undertake cost is thrown 2 times, operation maintains cost low, operating mode is constant below fluctuant perhaps and lesser premise, output effect is stable. Its equipment unit facilitates simply operation, waste gas purifies efficiency to be able to be amounted to 85% the left and right sides, craft designs reasonable condition, basic contented country or standard of local industry exhaust emission. Its belong to an environment friendly model purify engineering technology, purify the effect complete, degradation of waste gas composition is the avirulent hurtless material such as carbon dioxide and water, without 2 pollution arises, moving zoology environmental protection is safe, risk factor lowest. Biology purifies technological equipment to cover an area of an area big, apply to low density, fresh gale measures operating mode project, operating mode stability has rigid requirement, contain heavy metal discretion of project of antiseptic pollutant project is used.

　　 Investment cost and economic benefits are evaluated

Biology purifies craft to design cost to be between 50-80w commonly, later period operation safeguards eliminate to overhaul as normal as necessary equipment movement artificially besides necessary charge of electricity, the project with stable operation does not have cost investment 2 times, it is all waste gas in purifying technological equipment, operation safeguards the technology of cost lowest, especially project of project of large wind force, advantage particularly apparent, operation of average later period maintains cost but low control to 0.5w. With other technological equipment contrast rises, besides Gao Zhi of one-time investment cost, its operation and design engineering technology are difficulty, company of engineering of general environmental protection perhaps designs a company, design experience and operation experience data without opposite project, be project of result of very difficult make it, when accordingly the enterprise chooses biology to purify craft, need undertakes strictly to the supplier examine and verify and make an on-the-spot investigation.

　　 Craft evaluation and successful case

Do biology to purify craft, need transforms project operating mode the environment that will get used to biology to purify, rubber industry waste gas its composition is most easily microbial metabolism is used up, if can indulge engineering technology to do a design to improve as far as possible, basically can solve the environmental protection problem on the project. Purify craft to tell with respect to biology, mature quite in foreign application, germany and Japan, the main application such as Holand is purified at effluvial gas, often apply at sewage disposal deodorization, rubbish cram deodorization, review domestic and international, the effect on applied deodorization project is very ideal, because this purifies a project to go up in balata waste gas, pollutant of the part in its composition also belongs to effluvial gas, have similar place with cost of the contaminant in above industry, design reasonable, operating mode to be able to design contented biology to purify a condition to fall in technological equipment environment consequently, can finish environmental protection job basically, the enterprise can reap better environmental protection benefit.
