Technical field
The present invention relates to technical field of waste gas treatment, relate in particular to a kind of comprehensive processing method and VOCs treatment device of organic exhaust gas.
Background technology
Along with the development of society, people's environmental consciousness is more and more stronger.On the one hand, expanding economy inevitably will produce certain pollution in the present stage of people's understanding; On the other hand, the mankind's progress is also had higher requirement to own residing living environment, and masses' environmental pollution is had strong complaints, and environmental administrations at different levels are also more and more stricter to the restriction of pollutant effulent.The unification that how to obtain economic benefit and environment is the new problem of facing mankind.
Discharging in process of production volatile organic matter (VOC) is pollutant atmosphere, the arch-criminal who is detrimental to health.VOC invades people's nerve, blood, breathing and fertility system, and especially common triphen (benzene, toluene and dimethylbenzene) waste gas, by breathing, in the skin intrusive body, gently makes the people dizzy, dizzy, nauseating, and is heavy cause alpastic anemia, cancer etc.Workman and masses' poisoning are seen in the newpapers and periodicals media repeatedly.
Present stage, China mainly is faced with following problem to the improvement of environment:
1, plant gas generally only enters in air after simple water sprinkling equipment is processed, or by entering in air after the processing such as charcoal absorption.
2, because of the technical problem for the treatment of facility itself, the not high or processing cost of plant gas improvement rate and cost of investment are too high.
3, typically the improvement of factory's organic exhaust gas adopts the water spray to add the active carbon adsorption technological process more, and by regularly replacing activated carbon (or regenerated carbon) to guarantee adsorption effect.This technique not only needs high investment and operating cost, also need the specialty administrative staff, and the replacing of later stage activated carbon and regeneration also quite the trouble.
4, China's air quality is generally poor, and in air, PM10 and PM2.5 index are higher, serious threat people's health, and find Prevention Technique efficient, low consumption becomes one of study hotspot for this reason.
5, the situation is tense for urban ecological environment, and the center tropical island effect is remarkable.The roof of large tracts of land grey and black is the one of the main reasons of urban heat land effect, is also unemployed last block space resource.
6, soil is nervous, can realize that the soil of afforesting is fewer and feweri, and the quickening of urbanization process is had higher requirement to the urban afforestation land used.
