Description
Technical field
The invention belongs to field of environment protection, particularly a kind of waste gas filter.
Background technology
Along with the fast development of science and technology, the attention of people to environment is also more and more higher, and the discharge standard of environment is also more and more stricter.Few places still adopts burning coal to exchange the mode of heat energy for, containing a large amount of pollutants such as sour gas (as sulfurous gas), dust, heavy metal in the flue gas of fired coal combustion, therefore needs to carry out purification control to flue gas.
At present, people use maximum in flue gas desulfurization: absorb the sour gas in flue gas by absorbent slurry.The flue gas self-temperature produced due to fired coal combustion is higher, and the gas componant more complicated in flue gas, have higher requirement to the temperature tolerance of desulphurization plant, corrosion resistance, its desulfuration efficiency is also poor, and in exhaust process, have part dust accumulation inner at device, not easy cleaning.
And dust, unfiltered flue gas directly drain into air, the demand of not only discontented sufficient environmental protection, also produces directly harm to human body.
Summary of the invention
The object of the present invention is to provide a kind of waste gas filter, overcome above-mentioned shortcoming, it manufactures, install simply; floor space is little, not only economy but also practical, is conducive to disposing the poisonous gas and dust that produce in fired coal combustion process; efficiently solve exhaust pollution problems, protect atmospheric environment.
For achieving the above object, technical scheme provided by the invention is as follows: a kind of waste gas filter, comprise the air inlet pipe, filter, tube connector and the chimney that are communicated with successively, be provided with activated carbon filter layer in filter, activated carbon filter layer comprises left side activated carbon filtration plate and right activation charcoal filter; Left side activated carbon filtration plate and right activation charcoal filter from top to bottom interleaved are also located in the arranged on left and right sides of corresponding filter madial wall respectively; Tube connector outer wall is provided with spraying ventilating device;
The madial wall of chimney is provided with upper and lower staggered left supported plate and right supported plate, and left supported plate is provided with the pre-spraying ventilating device of flue gas, and right supported plate is provided with flue gas spray desulfurizer; Chimney bottom is provided with discharge outlet; Wherein, the bottom of filter is funnel type, and the opening part of bottom is provided with slagging-off valve.
Beneficial effect of the present invention is as follows: 1, be provided with activated carbon filter layer in filter, and activated carbon filter layer comprises left side activated carbon filtration plate and right activation charcoal filter; Left side activated carbon filtration plate and right activation charcoal filter from top to bottom interleaved are also located in the arranged on left and right sides of corresponding filter madial wall respectively.After waste gas enters filter, run between the upper and lower every the left and right side activated carbon filtration plate be arranged alternately, activated carbon filtration plate forms the laddering stop of one deck, one deck to waste gas, most of dust in waste gas are kept off by the activated carbon filtration plate resistance of ground floor, small part dust enters the activated carbon filtration plate of the second layer along with waste gas and is kept off by the second activated carbon filtration plate resistance, the dust of few part is only had then to enter lower one deck activated carbon filtration plate or more lower one deck activated carbon filtration plate, after said process, dust is temporarily adsorbed in the activated carbon filtration plate of each layer, and after toxic emission stops, most of dust (dust on the activated carbon filtration plate of mainly ground floor and the second layer) is according to Action of Gravity Field, dust drops and is gathered in the bottom of filter, the number of plies of activated carbon filtration plate is decided according to the actual requirements.
Meanwhile, waste gas pours in layer upon layer activated carbon filtration plate and filters, and most of impurity in waste gas is cleaned; And one deck, layer of active carbon filter also form slow resistance to waste gas, have delayed the time of waste gas discharge filter, have improve strainability, active carbon itself has the function being absorbed with poisonous gas, in being the increase in the cleannes of waste gas simultaneously.
2, tube connector outer wall is provided with spraying ventilating device.When waste gas is after the first round filters, pour in tube connector, now there is the higher problem of temperature in waste gas after assembling in a large number, and spraying ventilating device can carry out the cooling of the first round to tube connector outer wall, suitably reduces the gas in tube connector; And carry out the best results of first round cooling measure herein, if arrange spraying ventilating device in the filter, cold water is when filter stays downwards, and cold water heat absorption can become hot water gradually, is unfavorable for cooling.
3, the madial wall of chimney is provided with upper and lower staggered left supported plate and right supported plate, and left supported plate is provided with the pre-spraying ventilating device of flue gas, and right supported plate is provided with flue gas spray desulfurizer.Waste gas after first round purification, finally enter into chimney, chimney interior is similar with filter, the pre-spraying ventilating device of flue gas and flue gas spray desulfurizer are located on two support plates of left and right respectively, first undertaken second by the pre-spraying ventilating device of flue gas takes turns cooling to waste gas, then desulfurization process is carried out by flue gas spray desulfurizer again, subsequently again by the cooling of next group flue gas pre-spraying ventilating device (quantity of left supported plate and right supported plate and the visual actual conditions of the quantity of the pre-spraying ventilating device of supporting flue gas and flue gas spray desulfurizer are arranged), so circulate; Realize the filtration of waste gas, make waste gas reach discharge standard, finally enter in air, protect environment.
4, wherein, the bottom of filter is funnel type, and the opening part of bottom is provided with slagging-off valve.After toxic emission stops, great majority are adsorbed in dust on activated carbon filtration plate (dust on the activated carbon filtration plate of mainly ground floor and the second layer) according to Action of Gravity Field, dust drops and is gathered in the bottom of filter, filter in funnel type, so dust rests on the opening of the bottom of filter; Operator only need open slagging-off valve or tap through the bottom surface of filter gently, and then opens slagging-off valve (this kind of situation, just in order to make dust drop fully at the opening part of bottom), and dust can be made to be discharged outside device.Meanwhile, in order to improve cleaning performance, also available water is cleaned, and after cleaning, is mingled with the sewage of dust automatically from the opening part discharger of bottom.
Further, the pre-spraying ventilating device of described flue gas and flue gas spray desulfurizer are equipped with two groups of shower nozzles.
Further, the both sides of described filter bottom offer and hold dirt groove, and hold the opening part that dirt groove is communicated to bottom.
Further, the exhaust ports of described chimney is provided with the active carbon slab for drying.
