What side does the factor that affects waste gas to administer craft have?

　　 1, waste gas composition. This is the requirement of craft of certain off-gas treatment. Organic waste gas if constituent purer, concentration is higher, facilitate reclaim, can use activated carbon commonly (activated carbon fiber) reclaim; If part is complex, detached difficult, reclaim value is little, can adopt catalytic combustion, too low to chroma can adopt the combustion after condensing first, too low to chroma, can adopt the law such as smooth solution, plasma. Can adopt conventional technology according to property of aeriform chroma, gas, if smooth catalysis oxidizes,wait craft a moment.

2, aeriform relative humidity. Organic off-gas treatment is used commonly wet when handling a way, we consider aeriform relative humidity rarely, say filter of chemical washer, biology is waited a moment for example; If do type to handle a way, we often want high humidity system dehumidify, fall aeriform relative humidity 65% the following. Because aeriform humidity crosses tall meeting to handle a law bring a lot of troubles to dry type,this is, for example: Adopt corona law to handle waste gas, humidity is exorbitant, air is very easy by electric field puncture, cause equipment trouble; If equipment of organic off-gas treatment adopts activated carbon adsorption, the vapor in air can make activated carbon adsorption very quickly saturated, reduce the adsorptive capacity of pair of harmful gas, humidity still can make dust adheres to high too the surface in filter, increase equipment to control damage, reduce processing efficiency; Exorbitant humidity still can handle equipment to bring safe hidden trouble to air, be like the wiring terminal of equipment, easy short circuit, the very easy also puncture such as caboodle of capacitance of switch power source, silicon (the limits of beautiful job temperature of component of general electric equipment is controlled for 20 Celsius, relative humidity is 45%-65%

3, aeriform temperature. Temperature passes expensive gas, there is very big limitation on processing means, so we want high temperature gas commonly undertake dropping in temperature handling. Contain gaseous state for instance volatile organic matter (VOCS) high temperature gas, average temperature is like prep above 50 Celsius, cannot adopt activated carbon adsorption, be like prep above 100 Celsius, activated carbon loses the adsorptive ability to contaminant to be being met. Equipment of organic off-gas treatment in addition high temperature gas, the electronic original that zeolite runner adsorption condenses device to be able to cause air to handle equipment is fast ageing, lower the service life of equipment; Component of a lot of off-gas treatment, wait like filter, also can suffer temperature effect, the processing capacity that reduces facility and use safety. Although discharge of all sorts of glow discharge such as plasma of smooth catalysis oxidation, low temperature, corona, medium holds back discharge to wait,handle way, temperature is higher, the energy that gas needs to absorb is lower, below coequal power circumstance, the processing effect of high temperature gas is better instead, but the equipment oneself that because participate in,purifies a process is high temperature resistant conditional limitation, often we still want to go to air thermal drop can operate temperature (it is 50 Celsius commonly) the following.

4, discharge waste gas to having an organization, we still need to consider to discharge baric force. This is the requirement of fan type selecting. Choose appropriate fan, not only OK and energy-saving reduce cost, and the service life that can prolong equipment, reduce move uphold charge, reduce tone to try difficulty.

5, dust quantity. Overmuch dust also is an element that brings about equipment to handle ability to reduce. Be like, UV light sees equipment, dust is more, adhere to easily go up in tube wall, if clear not in time, can reduce ultraviolet work efficiency greatly, the index that short of designs beforehand. Dust still can cause the adsorptive material such as sieve of activated carbon, active alumina, element toxic, abate adsorptive ability, increase change the charge of sorbent. Company of organic off-gas treatment’s many dust also is deadly to influence of component of electronic electric equipment, mix to distribution so equipment unifinication purifying device, airy pretreatment appears especially important. Many dust can cause the explosion of equipment even. Dust is admirable to the design wet the impact that handles equipment is not big. Do type to handle equipment commonly, dust measures 200mg/m3 of unfavorable prep above.

The place on put together narrates: To engineer of an off-gas treatment, must have knowledge to waste gas. Occasionally the client is blind, cannot offer above in detail specific data. Our need concludes according to the manufacturing technology of Party A roughly waste gas circumstance, undertake making an on-the-spot investigation in detail to client spot even, make technology of corresponding off-gas treatment eventually
