Further, also be provided with tank, this tank is positioned at the below of described inlet plenum and neutralization chamber, and the wherein part of described air inlet is positioned at tank.
Further, described filtering agent is several baton rounds, and baton round comprises the hollow cylinder at middle part and outside annulus, this cylindrical axis and the radially vertical of annulus and the center of circle by annulus, and several dowels are arranged between cylinder and the annulus.
Further, described tank is provided with drainpipe, water inlet pipe and perspective window.
Compared with prior art; the present invention not only can remove the following fine solid particle of 0.1 μ m in the gas; various pernicious gases in also purifying air simultaneously; guaranteed eliminating gas cleaning degree, helped environmental protection, this equipment investment is few; simple in structure; easy for installation, final-period management that need not be special, running cost is low.
Description of drawings
Fig. 1 is the structural representation of gas cleaning plant of the present invention;
Fig. 2 is the structural representation of filtering agent among Fig. 1.
The specific embodiment
Among Fig. 1, the top in the cavity 1 is set side by side with inlet plenum 2, neutralization chamber 3 and exhaust chamber 4, and the bottom in the cavity 1 is provided with tank 5.The upper end of neutralization chamber 3 links together by the top of dividing plate 35 with cavity 1, in wherein a part of water that is immersed in the tank 5 of lower end, the both sides, front and back link to each other with the inner surface of cavity 1 respectively, be filled with numerous filtering agent 18 in the neutralization chamber 3, neutralization chamber 3 has air inlet 32 and gas outlet 33, air inlet 32 and 33 places, gas outlet all are provided with filter, to prevent that filtering agent 18 is scattered out in neutralization chamber 3, air inlet 32 is arranged on the position a little on the upper side, close bottom of neutralization chamber 3, gas outlet 33 is arranged on the position a little on the lower side, close top of neutralization chamber 3, air inlet 32 is arranged in tank 5 towards a side and the partial-air admission mouth 32 of inlet plenum 2, gas outlet 33 is towards a side of exhaust chamber 4, neutralization chamber 3 is by self and tank 5, and the inlet plenum 2 and the exhaust chamber 4 of its left and right sides are separated becomes two airtight each other spaces.Inlet plenum 2 is provided with high-temperature gas air inlet pipe 21, and inlet plenum 2 is communicated with neutralization chamber 3 by air inlet 32.The top of exhaust chamber 4 is provided with and the extraneous blast pipe 41 that communicates, between the exhaust outlet 33 of blast pipe 41 and neutralization chamber 3, be provided with water spacer assembly 42, this water spacer assembly 42 is the some pipelines that have aperture, the two ends of pipeline link to each other with the outer surface of neutralization chamber 3 and the inner surface of cavity 1 respectively, the end that pipeline links to each other with cavity 1 communicates with extraneous water source, and the water of the aperture ejection on the pipeline forms water curtain on the gas passage between exhaust outlet 33 and the blast pipe 41.Tank 5 is provided with feed pipe 51, perspective window 52 and drainpipe 53, and feed pipe 51 links to each other with external water source, and drainpipe 53 is positioned at the middle and lower part of tank 5, and an end of drainpipe 53 communicates with the external world.
As illustrated in fig. 1 and 2, link together after two similar semicircle spheroids interlace and constitute neutralization chamber 3, filtering agent 18 in neutralization chamber 3 for plastic material make spherical, filtering agent 18 comprises that the middle part is hollow cylinder 181, outside middle place at cylinder 181 is provided with an annulus 182, annulus 182 radially with the axis normal of this cylinder 181, the axis of cylinder 181 is by the center of circle of annulus 182, some dowels 183 link together cylinder 181 and annulus 182.
During work, the high-temperature gas that contains fine solid particle and various pernicious gases, or the gas that industry is discharged is at first through after the conventional purifier processing, big dust particle in the gas is effectively removed, but also has 0.1 μ m following fine solid particle and various pernicious gas in this gas.This gas that contains fine solid particle and various pernicious gases, temperature should remain on 250 ℃-700 ℃ high temperature before entering this device, this high-temperature gas at first enters inlet plenum 2 by air inlet pipe 21, because inlet plenum 2 is a sealing chamber, so high-temperature gas can only enter neutralization chamber 3 by the air inlet 32 of neutralization chamber 3, when high-temperature gas moves in neutralization chamber 3, neutralization reaction takes place in the filtering agent 34 in pernicious gas in the high-temperature gas and the neutralization chamber 3, be transformed into innocuous gas, innocuous gas enters exhaust chamber 4 by the gas outlet 33 on neutralization chamber 3 tops then, again by the water curtain between the blast pipe 41 of gas outlet 33 and exhaust chamber 4, under the effect of water curtain, fine solid particle in the gas is along with water enters in the tank 5, thereby removed the fine solid particle in the gas, the gas that does not contain harmful gas and fine solid particle after purifying is then discharged by blast pipe 41.
In the above-mentioned course of work, the temperature that enters the high-temperature gas in the inlet plenum 2 is 250 ℃-700 ℃, and contains nitrogen oxide (NOx), carbon monoxide (CO) and hydrocarbon pernicious gases such as (HC) in the high-temperature gas.When high-temperature gas enters neutralization chamber 3 by air inlet 32, because the part of air inlet 32 is positioned at tank 5, and the temperature of water differs bigger in filtering agent 18 in the temperature of high-temperature gas and the neutralization chamber 3 and the tank 5, thereby the steam that also can produce of the water in the tank 5, the dewfall phenomenon can appear on filtering agent 18 surfaces, steam is attached on the baton round filtering agent 18 with the motion of high-temperature gas, so the part fine solid particle in the high-temperature gas is attached on the baton round.Enter in the neutralization chamber 3 with certain pressure in moment and work as high-temperature gas, filtering agent 18 is produced certain impulsive force, in addition, because the special construction of neutralization chamber 3 and filtering agent 18, in neutralization chamber 3, produce vortex phenomenon, make pernicious gas and steam generation neutralization reaction, be transformed into nitrogen (N
2) and carbon dioxide (CO
2) innocuous gas and water.Its chemical reaction is as follows:
1, for the NO in the high-temperature gas
