廢氣處理設(shè)備用哪種風(fēng)管好？

Which kind of air duct is good for waste gas treatment and environmental protection equipment?

隨著時代的進步，科技的發(fā)展，我國對所居住的環(huán)境及人們的生存空間越來越重視?，F(xiàn)在工業(yè)發(fā)展速度越來越快，伴隨著制藥、化工、冶金、電鍍、生物、電子等行業(yè)的高速發(fā)展，這些行業(yè)在生產(chǎn)中所產(chǎn)生的有害物質(zhì)及氣體得到了大眾的高度關(guān)注。所以廢氣處理需要用到螺旋風(fēng)管。

With the progress of the times and the development of science and technology, China pays more and more attention to the living environment and people's living space. With the rapid development of pharmaceutical, chemical, metallurgical, electroplating, biological, electronic and other industries, the harmful substances and gases produced in the production of these industries have been highly concerned by the public. Therefore, spiral air duct is required for waste gas treatment.

工件在淬火及回火的過程中產(chǎn)生大量含有炭黑、煙塵等成分復(fù)雜的油煙，而油煙中含有大量的苯并芘等致癌物，這些油煙排放的車間會對工人健康造成危害，直接排放到車間外又會對環(huán)境造成污染。另外，油煙的冷凝物附著在設(shè)備上，會污染設(shè)備，容易造成電器拉弧或短路等故障，從而影響設(shè)備的正常運行。因此，隨著對環(huán)境保護要求的日益重視和企業(yè)清潔生產(chǎn)意識的提高，熱處理油煙的收集和處理將會越來越重要。及時治理、凈化這些有害物質(zhì)及有害氣體成為工作者的首要任務(wù)。

In the process of quenching and tempering, workpieces produce a large number of lampblack with complex components such as carbon black and smoke, and lampblack contains a large number of carcinogens such as benzopyrene. The workshop where these lampblack is discharged will cause harm to workers' health, and directly discharged outside the workshop will cause pollution to the environment. In addition, the condensate of oil fume attached to the equipment will pollute the equipment and easily cause electrical arcing or short circuit and other faults, thus affecting the normal operation of the equipment. Therefore, with the increasing attention of the state to environmental protection requirements and the improvement of enterprises' awareness of cleaner production, the collection and treatment of heat treatment lampblack will become more and more important. Timely treatment and purification of these harmful substances and gases has become the primary task of environmental protection workers.

從目前廢氣的排放狀況，主要是粉塵、油煙、非甲烷總烴。非甲烷總烴包括烷烴、烯烴、芳香烴和含氧烴等組成成分。大氣中的NMHC超過一些濃度，除直接對人體健康有害外，在一些條件下經(jīng)日光照射還能產(chǎn)生光化學(xué)煙霧，對環(huán)境和人類造成危害。

At present, the exhaust gas mainly includes dust, oil fume and non methane total hydrocarbon. Non methane total hydrocarbons include alkanes, olefins, aromatic hydrocarbons and oxygenated hydrocarbons. NMHC in the atmosphere exceeds some concentrations, which is not only directly harmful to human health, but also can produce photochemical smoke after sunlight exposure under some conditions, causing harm to the environment and human beings.

廢氣的處理方法種螺旋風(fēng)管類繁多，特點各異，常用的有冷凝法、水噴淋法、吸收法、吸附法、熱力燃燒法、催化燃燒法等。針對每個公司的生產(chǎn)特點及規(guī)律，根據(jù)車間所產(chǎn)生的廢氣種類、廢氣量及使用成本核算，選用費用低、耗能少、無二次污染的處理方法。

There are many kinds of spiral air ducts for waste gas treatment with different characteristics. The commonly used methods include condensation, water spray, absorption, adsorption, thermal combustion, catalytic combustion, etc. According to the production characteristics and laws of each company, the treatment method with low cost, less energy consumption and no secondary pollution is selected according to the type, quantity and use cost accounting of the waste gas generated by the workshop.
