Abstract
The invention relates to an organic waste gas purifier. The organic waste gas purifier comprises an adsorption unit and a plasma decomposition unit; organic waste gas is purified by virtue of the filtering of a filter and the adsorption of active carbon in a runner adsorption device and then is discharged into upper air; the regenerated hot air formed by virtue of the electric heating is used for desorbing and regenerating the runner adsorption device, the generated concentrated volatile organic matter air enters a filler bed medium blocking discharging reactor to be degraded and mineralized into carbon dioxide and water, and the waste heat of the exhaust gas is recovered, so that the energy consumption is saved. An adsorption runner with a honeycomb structure is combined with a plasma purifier, so that the organic waste gas purifier is very suitable for purifying the high-air-volume low-concentration organic waste gas.
Description
Technical field
The invention belongs to environmental protection technical field, relate to a kind of organic waste gas purifier.
Background technology
Not only endangering human health but also serious environment pollution due to volatile organic matter, therefore reducing that the discharge of volatile organic matter become is the important issue of society.Many volatile organic matters are proved can carcinogenic mutagenesis.And they are once enter atmospheric thermodynamics, can cause the generation of photochemical fog, secondary particulate and ozone.Although process optimizing is to reduce the feasible method that volatile organic matter pollutes, but for adapting to day by day serious global pollution problem, the technology for eliminating of more effective economy still requires study.
Summary of the invention
It is an object of the invention to provide a kind of organic waste gas purifier, including absorbing unit and plasma resolving cell；
Described absorbing unit includes filter, runner adsorber and air-introduced machine, filtering air inlet is connected with collecting contaminated air pipeline, runner adsorber is built with Alveolate activated carbon, it is divided into adsorption zone, thermal desorption district and cooling zone, rotate with 2-8 rotary speed per hour under the driving of buncher, adsorption zone, thermal desorption district and cooling zone respectively be correspondingly provided with absorption air inlet, absorption gas outlet, thermal desorption air inlet, thermal desorption gas outlet, cooling air inlet and cooling gas outlet, and respectively with contaminated air, cooling air, regenerated heat air pipeline be connected；Filter outlet mouth adsorbs air inlet with runner adsorber and is connected, and runner adsorber absorption gas outlet is connected with air-introduced machine；
Described plasma resolving cell includes heat exchanger, electric heater, air-introduced machine and plasma purifier；Runner adsorber cooling air inlet is connected with collecting cooling air line, heat exchanger adopts indirect type heat exchanger, it is provided with regeneration air inlet, regeneration gas outlet, tail gas air intake and tail gas gas outlet, runner adsorber cooling gas outlet regenerates air inlet with heat exchanger and is connected, heat exchanger regeneration gas outlet is connected with electric heater air inlet, electric heater gas outlet is connected with runner adsorber thermal desorption air inlet, plasma purifier adopts packed bed dielectric barrier discharge reactor, runner adsorber thermal desorption gas outlet is connected with plasma purifier air inlet by blower fan, plasma purifier gas outlet is connected with heat exchanger tail gas air inlet.
The purification method of above-mentioned a kind of organic waste gas purifier, comprise the following steps: 1) after contaminated air containing volatile organic matter removes particulate matter or stickum by filter, enter the adsorption zone of runner adsorber, in contaminated air, the adsorbed agent of contained volatile organic matter is adsorbed, after air is purified, enter air-introduced machine high altitude discharge by adsorbing gas outlet；2) along with the rotation of runner adsorber, adsorbing saturated runner adsorber and enter into thermal desorption district, with regenerated heat air contact process, volatile organic matter is got off to be changed into concentration volatile organic matter by thermal desorption, and runner adsorber is regenerated；Runner adsorber after regeneration forwards cooling zone to, after cooling air heat-exchange cooling, returns to adsorption zone, completes the cyclic process of primary sorption-thermal desorption-cooling；Be generally the 1/10-1/20 of the contaminated air air quantity of process due to the air quantity of regenerated heat air, regenerative process thermal desorption gas outlet volatile organic matter in air concentration is 10-20 times of the contaminated air concentration processed；3) air containing concentration volatile organic matter is sent into plasma purifier by air-introduced machine, at a large amount of active specy (charged particles, excited state species, free radical, electronics and photon) effect under, volatile organic matter in air is thoroughly degraded and mineralising is transformed into carbon dioxide and water small-molecule substance, high altitude discharge after carrying out heat exchange in heat exchanger with the air coming self-rotation wheel adsorber cooling zone from the tail gas of plasma purifier discharge, the heating of the waste heat recovery through heat exchanger of the air of runner adsorber cooling zone and electric heater, temperature rises to 200 DEG C, it is changed into regenerated heat air, enter runner adsorber thermal desorption district, complete a thermal desorption-plasma catabolic process.
