Description
Technical field
The invention belongs to field of environment protection equipment, be specifically related to a kind of Painting Shop VOC dust purification system.
Background technology
When carrying out application, the dust that in the air of paint spray booth, content is a large amount of and VOC, these dust and VOC to harm very greatly, need to be taken a breath by exhaust column, the air in purification paint spray booth.Existing air regenerating device is all generally directly adopt air exhauster to carry out forced convertion to air, and this kind of mode causes harmful dust and VOC to be directly discharged in air, causes environmental pollution.
Summary of the invention
The object of the invention is to provide a kind of Painting Shop VOC dust purification system, solves harmful dusts a large amount of in existing paint spray booth and VOC is directly discharged into the problem that air causes environmental pollution.
Technical scheme of the present invention is: a kind of Painting Shop VOC dust purification system, comprise air exhauster, active carbon filter, drier, electrostatic precipitator, described air exhauster, active carbon filter, drier is connected by pipeline successively with electrostatic precipitator, described air exhauster inlet end is connected with the first air inlet pipe and the second air inlet pipe, first air inlet pipe is communicated with furniture paint booth, second air inlet pipe is communicated with outside atmosphere, first air inlet pipe and the second air inlet pipe arrange the first intake valve and the second intake valve respectively, the air inlet of active carbon filter is connected with tank, between tank and active carbon filter, water storage valve is set, the gas outlet of active carbon filter is connected with steam evaporator, between active carbon filter and drier, outlet valve is set.
Further, steam evaporator is made up of water tank and heater.
Further, drier is Calcium oxide drier, is made up of housing and the calcium oxide particle be filled in housing.
In the present invention, air in furniture paint booth pumps into and passes through active carbon filter by air exhauster, because active carbon has stronger adsorption capacity to VOC, thus the VOC in air is removed, dust is then deviate from by the electrostatic precipitator of system tail end, because electrostatic precipitation has requirement to humidity, in order to avoid moisture reduces dust removing effects, drier is set between active carbon filter and electrostatic precipitator, deviates from the moisture in air-flow, improve the effect of electrostatic precipitation.
Active carbon and drier absorption a certain amount of after be just saturated, need to regenerate, during regeneration, close outlet valve, open water storage valve, produce steam by steam evaporator, steam carries out wash-out by active carbon filter to absorption material on the activated carbon, flow in tank, after wash-out, containing large quantity of moisture on active carbon, adsorption capacity is not enough, need to remove moisture, now close the first intake valve, open the second intake valve, by air exhauster, active carbon is blown, remove the moisture of attachment on it, complete regeneration.
The present invention compared with prior art tool has the following advantages:
The present invention, by the coupling of active carbon filter and electrostatic precipitator, can effectively remove VOC and dust, and system stability is reliable, and operating cost is low.
