The feed waste gas treatment device has the advantages of good removal effect, low energy consumption and energy saving and emission reduction.
Description
Technical field
The utility model relates to a kind of emission-control equipment, particularly a kind of feed emission-control equipment.
Background technology
In the Feed Manufacturing process, need HTHP to carry out evaporate to dryness; Contain the steam that the foul smell composition is trimethylamine and ammonia in a large number and in the evaporate to dryness process, can produce; Also contain a large amount of glutamic acid, TMAO in the steam; But TMAO is extremely unsettled, and a part of TMAO begins to change gradually reduction, generates the trimethylamine that has fishy smell.As time goes on, the rising of temperature, the trimethylamine of generation constantly increases, and it is more and more denseer that fishlike smell also just becomes, and fishy smell waste gas just occurred.Trimethylamine normal temperature for colourless gas, has fish raw meat stench down, and is water-soluble, ethanol, and ether, inflammable, poisonous.Current domestic production Feed Enterprise is not administered trimethylamine basically, directly enters atmosphere, causes environmental pollution.Even handle, also be with trimethylamine gas after condensation, send into boiler combustion; But it is immature at equipment, technology and process aspect; Can't reach environmental protection requirement, have its branch problem, cause the deterioration of air quality equally to another kind of form pollutant.
The utility model content
The utility model technical problem to be solved is to provide a kind of removal effect good, and energy consumption is low, the feed emission-control equipment of energy-saving and emission-reduction.
In order to solve above technical problem, the utility model provides a kind of feed emission-control equipment, and this bottom of device is provided with circulating water pool; Top is spray column, the external a plurality of water pumps of circulating water pool, each water pump respectively with spray column in atomizer be connected; The spray column top is provided with moisture separator, and waste gas is sent into circulating water pool, after spray column spray, moisture separator separate; Mist gets into the deodorizing of low temperature plasma purification utensil, and cleaned air passes is discharged through air exhauster.
Described circulating water pool is provided with overflow pipe, and the part spray that has more flows out with overflow pipe, enters the workshop reuse.
Be provided with the water circulation between described spray column and circulating water pool, the moisture separator.
The operation principle of the utility model: the waste gas in the chimney enters in the circulating water pool at the bottom of the spray column through chimney; Get in the spray column again in the waste gas of the big molecule harmful substance of preliminary removal, dust granules thing; Waste gas flows to the top of spray column from the bottom to top from the spray column bottom; With spray liquid reaction from top to bottom, further remove big molecule harmful substance, dust granules thing in the waste gas.
Waste gas main component through preliminary treatment is trimethylamine and steam, and the process moisture separator enters the low temperature plasma clarifier through pipeline after carrying out the aqueous vapor separation again.
The low temperature plasma clarifier of the utility model; Plus high-pressure high frequency alternating current between electrode, the surface generates micro discharge, induces simultaneously and causes high electric field; The moment high energy that high-frequency discharge produced is opened the chemical bond of some pernicious gas molecules, makes it to be decomposed into simple substance atom or harmless molecule; High electric field impels the free electron in the discharge space to quicken; Electronics will be accelerated in electric field and obtain enough energy this moment, and excite, dissociates, dissociates, combines with the gas molecule bump or reaction such as combination again, the free radical that generates many high energy electrons, cation, excited state particle and have strong strong oxidizing property; These active particles and part foul smell molecular collision combine; Under electric field action, make the foul smell molecule be in excitation state, the energy that obtains when the foul smell molecule is during greater than the binding energy of its molecular bond energy; The chemical bond rupture of foul smell molecule directly resolves into the simple substance atom or by the innocuous gas molecule of single atomic building; Produced simultaneously a large amount of OH, HO
2, O isoreactivity free radical and the extremely strong O of oxidisability
3,, finally generate harmless product with pernicious gas molecule generation chemical reaction.Mist is after the deodorizing of low temperature plasma purification utensil is handled, and production concentration is extremely low, is discharged from chimney by air exhauster, and the gas of discharge reaches national odorant pollutant discharge standard GB14554-93 fully.
The superior effect of the utility model is:
1) the utility model is handled feed waste gas, and removal effect reaches more than 99%, and air exhauster is low from the content of the feed waste gas that chimney is discharged;
2) circulatory pool of the utility model is provided with overflow pipe, and the part spray that has more can flow out with overflow pipe, enters the workshop reuse;
3) spray column of the utility model depends on atomizer high-temp waste gas is carried out water spray, has greatly increased the gas-liquid contact area, reduces the temperature of fish powder waste gases, reduces energy consumption, again raw material and water is carried out reuse, increases income, and enhances productivity;
4) the utility model adopts the low temperature plasma clarifier to carry out the deodorizing processing, meets the development trend of energy-saving and emission-reduction, and it is low to have energy consumption, handles advantage completely.

The specific embodiment
See also shown in the accompanying drawing, the utility model is done further to describe.
As shown in Figure 1, the utility model provides a kind of feed emission-control equipment, and this bottom of device is provided with circulating water pool 5; Top is spray column 1, circulating water pool 5 external a plurality of water pumps 4, each water pump 4 respectively with spray column in atomizer 9 be connected; Spray column 1 top is provided with moisture separator 6, and waste gas is sent into circulating water pool 5, after spray column 1 spray, moisture separator 6 separate; Mist gets into low temperature plasma clarifier 3 deodourizings, and cleaned air passes is discharged through air exhauster 7.
Described circulating water pool 5 is provided with overflow pipe 8, and the part spray that has more flows out with overflow pipe, enters the workshop reuse.Follow and pond 5 also is connected with factory building, thereby guarantee that the factory building water-in and water-out reach balance, save the factory building water resource, reduce water consumption; Get into circulating water pool 5 through the waste water behind the spray column 1 simultaneously, wherein contain the fish meal dust of a large amount of reusable edibles, can collect it and carry out recycle, thereby improve factory building production efficient.
