Description

A kind of dust proof workshop VOCs purifications reflux fresh air system
Technical field
The invention belongs to field of environment protection, specifically a kind of dust proof workshop VOCs purifications reflux fresh air system.
Background technology
In the industrial production, all conglomeraties often set dustless cleaning to realize the stringent control of product quality Workshop forms the production environment that constant temperature and humidity does clean stabilization, to ensure production or experimental study not impurity in by air Or the influence of dust.Such as the industries such as liquid crystal display panel production, edible cosmetic product processing and manufacturing, semiconductor.Dust proof workshop is set It puts and ensures product quality, but the closed environment that workshop is formed, the air quality in dust proof workshop is caused to be deteriorated.Particularly exist The industries such as electronic manufacture, spraying due to the use of organic solvent or cleaning agent, cause long-term existence in workshop certain density VOCs gases, on the one hand seriously affect personnel health, enterprise technology worker are on the other hand caused to replace frequent, it is artificial to increase enterprise Cost.For this problem, current main measure is ceaselessly to introduce outdoor fresh air by fresh air system to be solved. But there are problems for this method.The air quantity that one side fresh air system introduces is limited, still long-term existence one in dust proof workshop Fixed pollutant, on the other hand since outdoor air is there are impurity or dust, be unsatisfactory for dust proof workshop needs constant temperature and humidity, Dry clean condition requirement, system need to carry out respective handling, and which increase operation cost of enterprises.In addition, after fresh air system displacement If house exhaust directs out discharge, environmental pollution will be caused, do not meet environmental regulation requirement.Therefore it is badly in need of a kind of new For the fresh air system of dust proof workshop air quality control.Chinese patent literature CN 204629809U are in public affairs on April 14th, 2015 " the commercial space air cleaning unit " opened, including housing, housing is equipped with air inlet, air outlet, be equipped in housing air-introduced machine, Cloth wind guiding device, low temperature plasma pyrolysis oxidization reactor, ozone intercept decomposer, and the ozone intercepts decomposer Including multiple evenly distributed carbon fiber bags, be loaded with the catalyst of ozone decomposition in carbon fiber bag, the air-introduced machine be arranged on into At air port, air is sent into low temperature plasma pyrolysis oxidization reactor, low-temperature plasma by air-introduced machine by cloth wind guiding device Body pyrolysis oxidization reactor intercepts decomposer inlet end with ozone and connect, and ozone intercepts decomposer outlet side and connects with air outlet It is logical.
Invention content
Based on the above problem, the present invention provides a kind of dust proof workshop VOCs purifications reflux fresh air system, by low-temperature plasma Body-ozone decomposed integration apparatus is combined with fresh air system, can not only realize VOCs clean-up effects, moreover it is possible to according to It needs to provide fresh air in workshop.
In order to realize goal of the invention, the present invention adopts the following technical scheme that:A kind of dust proof workshop VOCs purifications reflux fresh air System, including workshop, air is back to workshop by circulating fan in workshop, and the communicating downstream of circulating fan is equipped with low temperature etc. Gas ions-ozone decomposed integration apparatus.
The dust proof workshop VOCs purification reflux fresh air system of the technical program design, on the basis of traditional workshop air draft, Increase low temperature plasma-ozone decomposed integration apparatus.Conventional low temperature plasma equipment can be produced when handling VOCs Raw more ozone, low temperature plasma used herein-ozone decomposed integration apparatus is then after low temperature plasma equipment End is mounted with ozono lysis apparatus, increases ozone decomposed function, after pending gas is made to pass through integration apparatus, fully achieves Decomposition.By such installation, the gas for being discharged from workshop can be made to be handled well, on the one hand meet discharge It is required that workshop use on the other hand can also be back to.
Preferably, the communicating downstream three-way pipe of low temperature plasma-ozone decomposed integration apparatus, passes through three-way pipe point Ambient atmosphere and mixing chamber are not connected to it;Another upstream end connection fresh-air fan of mixing chamber, downstream connection workshop;Three-way pipe Downstream and mixing chamber between be equipped with check valve, the conducting direction of check valve is three-way pipe to mixing chamber.Present design will be through Cross low temperature plasma-ozone decomposed integration apparatus treated that clean air is divided into two flow directions, it both can be directly to big Gas discharges, and is sent back in workshop again after being mixed with the ambient atmosphere that fresh-air fan is sent.Due to temperature in workshop and wet The requirement of degree generally requires to carry out the ambient atmosphere that fresh-air fan is sent into the adjusting of temperature and humidity, these, which are adjusted, needs to open Corresponding equipment is opened, adjusting process needs to expend certain energy consumption.And sent out of workshop by circulating fan to low temperature plasma- The air of ozone decomposed integration apparatus processing, need to dispose is VOCs problems, is all met in workshop in temperature and humidity The requirement used, this partial air send workshop use back to again after treatment, it is possible to reduce the work of temperature and humidity adjustment equipment Make load, reduce system energy consumption.
Preferably, regulating valve is equipped between three-way pipe and ambient atmosphere.The effect of regulating valve be adjust through low temperature etc. from Both amounts that the air of daughter-ozone decomposed integration apparatus processing is recycled to the amount that air discharges with sending workshop back to again The ratio between, so as to adjust the ratio that fresh air and cycle in the air in input workshop reuse air.
Preferably, it is additionally provided with oxygen content control system;Oxygen content control system is monitored including online oxygen content Equipment and oxygen content signal processor;Online oxygen content monitoring device is installed between mixing chamber and workshop, and and oxygen Cont signal processor signal connects;Oxygen content signal processor is connect with fresh-air fan and adjusting valve signal.It is empty in workshop Its oxygen content can reduce gas after use, and carbon dioxide content can rise, and be chronically in such air, can be to health It is unfavorable.This programme increases online oxygen content monitoring device in systems thus, and oxygen is carried out to the air that will be fed into workshop Content monitors, and related data is passed to oxygen content signal processor;The latter then judges i.e. according to preset fiducial value The number of the oxygen content in the air in workshop is will be fed into, needs to increase the ratio of fresh air in mixing air if oxygen content is relatively low Example.Oxygen content signal processor can be transmitted to fresh-air fan and regulating valve by signal at this time, corresponding to increase at fresh-air fan Air inflow, while increase from the discharge rate at regulating valve, so as to improve the oxygen content in workshop, ensure that air quality expires in workshop Sufficient personnel demand.
Preferably, connection is equipped with air cleaning facility between fresh-air fan and mixing chamber.Air cleaning facility can be with It purifies from extraneous air.
In conclusion the beneficial effects of the invention are as follows:By low temperature plasma-ozone decomposed integration apparatus and fresh air System in combination together, can not only realize VOCs clean-up effects, moreover it is possible to as needed for providing fresh air in workshop.
