Description
Technical field
The present invention relates to technical field of waste gas treatment, and in particular to a kind of waste gas treatment process.
Background technique
At present in exhaust gas production industry, following three kinds of methods are mainly used to the processing of the exhaust gas generated in production process,
First is that water absorption method, second is that catalytic burning method, third is that heating power incineration method.Water absorption method is last procedure in maleic anhydride production
Water absorption processing is carried out to maleic anhydride waste gas, due to containing benzene in maleic anhydride waste gas, and benzene is difficult to be dissolved in the water.Therefore, this is used
Kind method handles maleic anhydride waste gas, and effect is poor.Catalytic burning method is that maleic anhydride waste gas is preheating to the ignition temperature of catalyst
Degree, exhaust gas enters catalytic reactor after preheating, makes organic matter and oxygen in maleic anhydride waste gas that oxidation occur instead in catalyst surface
It answers, organic matter is finally made to be converted into the innocuous gas such as carbon dioxide and water vapour.The innocuous gas enters waste-heat recovery device, right
Waste heat is discharged into atmosphere after being recycled again.Since catalyst is more expensive, one-time investment is big.Again due to catalytic burning temperature compared with
Low, only 500~600 DEG C, so that the temperature into waste-heat recovery device is also low, the heat of recycling is also few.In addition, due to exhaust gas
The elements such as middle halogen, sulphur, phosphorus are higher, and these elements are to the toxic effect of catalyst, so that the service life of catalyst is not grown,
Therefore often more catalyst changeout, operating cost are higher for need.Heating power burning is that heat is sent into after maleic anhydride waste gas to be preheating to certain temperature
Power incinerator makes the incineration temperature of maleic anhydride waste gas reach 800 DEG C or more, in exhaust gas by the combustion-supporting burning of the fuel such as natural gas
Organic matter complete oxidation decomposes, and is sent into waste-heat recovery device by burning the flue gas generated, is discharged into again after progress thermal energy recycling big
Gas.
Summary of the invention
The present invention is intended to provide a kind of waste gas treatment process.
The invention provides the following technical scheme:
A kind of waste gas treatment process, exhaust gas are delivered to cyclone dust collectors by collection conduit collection, are dusted processing, lead to
It crosses that temperature is 35-40 DEG C by gas distributor, the exhaust gas of pressure 4000-12000Pa is uniformly sent into regenerative chamber, is inhaled by exhaust gas
Exhaust gas temperature is heated to the decomposition point temperature of organic matter in exhaust gas or more by the heat for receiving heat storage storage in regenerative chamber, then will
Exhaust gas exhaust gas introduces purifying column by air hose, and by packing layer, exhaust gas and absorbing liquid carry out gas-liquid two-phase and come into full contact with absorbing reaction,
Exhaust gas is discharged after purification, then after demisting plate dehydrating demisting by blower, and absorbing liquid is in tower bottom in tower top after water pump is pressurized
Spray and under, be finally back to tower bottom recycling, using spray column, by water pump shower water, most organic matter and
Dust attaches in water, carries out UV photodissociation purified treatment again after a small amount of organic exhaust gas discharge.
Dust in the cyclone dust collectors in exhaust gas rotates, and is separated grit from air-flow by means of centrifugal force
And it is trapped in wall, then so that grit is fallen into ash bucket by gravity.
The UV photodissociation purified treatment is that the oxygen molecule decomposed in air using high energy high ozone UV ultraviolet beam is generated
Free oxygen, because free oxygen it is unstable need in conjunction with oxygen molecule, and then generate ozone.
Compared with prior art, the beneficial effects of the present invention are: by the present invention in that exhaust gas and the indoor heat storage of accumulation of heat
Directly contact exchanges heat, and heat exchange efficiency is up to 85-90%, can by heating by the exhaust gases to after 600-700 DEG C, feeding thermal oxidizer into
Row burns, and present invention process is simple, easy to use, at low cost, and exhaust treatment efficiency is high, drops low exhaust gas emission, and it is dirty to reduce environment
Dye, meets market use demand, is conducive to the popularization of product.
