论述了厨房油烟气产生和原因及其在日常生活和生产中对人体健康的影响 ,提出了除油烟气的方法。并且介绍了一种既除油又降噪的净化装置。这种装置在厨房中应用取得了良好的效果。
Lampblack is the thermal decomposed product after a series of reactions of cooking oil and food at high temprature.Most contents of lampblack, such as heterocyclic amine, are poisonous.The effects of lampblack on human health are discussed and mainly in two aspects,i.e.(a) aspiration poisoning and (b)carcinogenic.The influenting factors concluded in the present paper are cooking temperature,kind of oil,kind of food and cooking method and time.To minimize the effects, concrete methods are introduced in practice for eliminating lampblack. Purifying methods can be classified to in two kinds.One is controlling pollution source,and the other is accelerating diffusion and dilution ot pollutant.A new purifying equipment of eliminating lampblack and reducing noise strength is presented in the present paper (Fig.1). The equipment is composed with two parts.The main function of the first is filtering,and the second is reducing noise.In the first part,three filters in line are used.The value of purifying ratio of oil vapor could reach 90% by using the purifier.Millipore plate silencer is used in the second part.And 20~25 dB of magnitude could be reached.The results from practice show that good effects could be obtained by using this equipment in kitchen.
