High-pressure suction fan 8 in device systems for forming negative pressure, to utilize negative pressure to the organic waste in each device systems Gas is aspirated, and realizes that the organic exhaust gas in device systems uninterruptedly circulates, high-pressure suction fan 8 is realized using the prior art.It is high Pressure air-introduced machine 8 is connected by air inducing pipeline 9 with the air outlet 314 of the shell 31 of photocatalytic oxidation device 3, photocatalytic-oxidation makeup The air inlet 33 for setting 3 shell 31 passes through the gas outlet 112 of air inducing pipeline 9 and the spray washing tower body 11 of spray washing system 1 It is connected.

The basic functional principle and workflow of the utility model:

1) under the negative-pressure ward effect that high-pressure suction fan 8 is formed, discharge contains a large amount of dust particulate matter and flue gas cigarette The organic exhaust gas of dirt enters spray washing tower body 11 via the air inlet 111 of spray washing tower body 11, contains a large amount of dust The air-flow of grain object and flue gas flue dust is when by the air inlet 111 of spray washing tower body 11, the atomization that is connected with air compressor machine The atomized drop that nozzle sprays drenches exacerbation, slows down what dust particle and flue gas flue dust in organic exhaust gas were flowed with air-flow Flow velocity had both improved cohesion rate and cohesion of the dust particle and flue gas flue dust in organic exhaust gas in ultrasonic coagulation section 10 Effect, but prevent dust particle and flue gas flue dust in organic exhaust gas with high pressure draught it is quick on alter and reduce spray washing tower Body 11 is to the effect of dust particle and flue gas flue dust washing filtering in organic exhaust gas, to effectively increase in organic exhaust gas Dust particle and flue gas flue dust removal effect.

2) by atomized drop drench aggravate after the air-flow containing a large amount of dust particulate matter and flue gas flue dust flow through it is super When sonic agglomeration section 10, homogenizing plate 71 makes what is entered from the air inlet 111 of spray washing tower body 11 to contain dust particle and cigarette The distribution of air flow of gas flue dust is to enter what gap between homogenizing plate 71 and ultrasonic coagulation section 10 was formed after uniform and stable air-flow In chamber, to issue ultrasonic wave using supersonic generator 72, and ultrasonic wave is emitted to chamber by ultrasonic oscillator 73, contained Fine particle in the air-flow of dust particle and flue gas flue dust agglomerates in the chamber, gradually condenses into the bigger powder of partial size Dirt or soot dust granule flow into the spray washing filtering that spray washing tower body 11 carries out particulate matter then as air-flow.

3) air-flow containing a large amount of dust particulate matter and flue gas flue dust Jing Guo ultrasonic coagulation is being sprayed using setting Wash the moisture film strainer that the multistorey strainer mesh of the smoke dust filter 12 in tower body 11 is formed, to dust particle in organic tail gas and Flue gas flue dust is adsorbed the washing filtering to realize organic tail gas, to reduce the dust particle and flue gas cigarette in organic exhaust gas Dirt flows out spray washing tower body 11 with air-flow.

4) clean gas flow of the smoke dust particle after 12 washing filtering of smoke dust filter enters electrocatalytic oxidation system System 2, the mosaic electrode packing layer 22 of electrocatalytic oxidation system 2 generate a large amount of hydroxyl radical free radical and high energy to air-flow after powered up Ionic agent active group DMF, piperidines, methylene chloride, trifluoracetic acid, dithioglycol, ether, acetonitrile in air-flow etc. is harmful dirty Dye object and living radical therein, which are rolled into a ball, to be chemically reacted, and a large amount of noxious pollutant is broken down into carbon dioxide, water, harmless Carboxylic acid.Electrocatalytic oxidation system 2 does not consume other raw materials, does not bring secondary pollution in addition to power consumption, water consume, is not necessarily to secondary treatment, And catalyst long service life.

5) air-flow after the oxidation of 2 electrolytic oxidation of electrocatalytic oxidation system enters photocatalytic-oxidation from air inlet 313 and disguises The photocatalysis chamber 311 for setting 3, containing water mist, mist of oil air-flow by shell 31 air inlet 313 when, be arranged in photocatalysis Oil gas separator 4 at the air inlet 313 of the shell 31 of oxidation unit 3, by 95% water mist in air-flow, mist of oil intercept At the air inlet 313 of shell 31 and formed water mist and oil mist particles inflow connect liquid box, not only can solve in combined treatment process In photocatalytic oxidation device in be easy to be influenced by water mist, the mist of oil of photocatalytic oxidation device front end, there is fluorescent tube difficulty and open Dynamic problem, can also thoroughly solve because water mist, mist of oil influence due to lead to problems such as burn fluorescent tube.

6) in the photocatalysis chamber 311 of photocatalytic oxidation device 3, microwave occurs the air-flow after mist of oil separating treatment Device 34 generates microwave-excitation and the generation ultraviolet light of the ultraviolet lamp tube 33 on lamp tube installation rack 32 is arranged in, and ultraviolet lamp tube 33 generates ultraviolet The light with alternating and continuous 318 surface layer of protrusion 317 and recess portion that light is radiated at 311 inner wall of photocatalysis chamber of shell 31 is urged On agent layer, and vortex is formed, so that reaction gas is well-dispersed in photocatalysis chamber 311, avoided because of reaction gas Directed flow it is too strong and lead to reaction gas and photochemical catalyst insufficient contact, to ensure that the effective of light-catalyzed reaction It carries out, improves the conversion ratio of reaction gas.

7) when using automatic cleaning model, pass through the cleaning frequency of the on-line automatic control on-line cleaning device 5 of control chip And scavenging period, it is not necessarily to manual intervention, control chip automatically controls starting booster pump according to pre-set programs, carries out to equipment clear It washes.Using physical effects such as cavitation, radiation pressure, acoustic streaming of the ultrasonic wave in clear water transmission, cleaned photocatalytic-oxidation is disguised It sets the dirt on 3 and generates pinch spalling effect, while cleaning solution can be promoted to chemically react with dirt, reach better cleaning The purpose of pipe fitting improves cleaning effect and cleaning efficiency, high degree of automation.

The foregoing is merely the better embodiment of the utility model, the utility model is not limited to above-mentioned embodiment party Formula, there may be the structural modifications that part is small in implementation process, if various changes or modifications to the utility model are not The spirit and scope of the utility model are detached from, and are belonged within the scope of the claims and equivalents of the utility model, then originally Utility model is also intended to encompass these modification and variations.
