Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain This utility model, is not used to limit this utility model.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of novel emission-control equipment that sprays paint, include oxidizing tower body 1, oxygen Changing and be provided with maintenance window 18 on tower body 1, oxidizing tower body 1 has discharge duct 9, discharge duct 9 by connecting pipeline 6 connection It is simultaneously connected with air-introduced machine 10, liquid collecting zone 2 at the bottom of reaction zone 3 in two ends are respectively arranged with tower up and down in oxidizing tower body 1 and tower, In tower, the top of reaction zone 3 is provided with ripple demister 12, and the bottom of ripple demister 12 is provided with nozzle 13, and nozzle 13 is one Planting bigbore nozzle 13, at the bottom of tower, liquid collecting zone 2 connection has water tank 8, the absorbing liquid in water tank 8 is UV/ OH oxidizing agent solution, water The side of case 8 is provided with water pump 11, and water pump 11 is connected with nozzle 13 by water pipe 7, is provided with several rotations in tower in reaction zone Stream plate 14, the centre position of spiral board 14 is provided with fixing seat 17, spiral board 14 be provided around collecting tank 19, neighbouring Spiral board 14 between connect have discharging tube 16, be provided with some quartz burners 15, oxidizing tower body in oxidizing tower body 1 Being provided with several flange seats 20 on the outer wall of 1, quartz burner 15 is fixed by flange seat 20, quartz burner 15 One end is movable with fixing seat 17 to be connected, and is connected in parallel by electric wire 5 between adjacent quartz burner 15.
Non-pump type water-screen cabinet 21, non-pump type water-screen cabinet 21 is had to include as it is shown in figure 1, the left side of oxidizing tower body 1 connects Cabinet 23 and be arranged on the tank 28 bottom cabinet 23, the left end of tank 28 is provided with air inlet 4, and the top of tank 28 is respectively Being provided with aspiration column 22 and water curtain plate 24, the top of aspiration column 22 is provided with dividing plate 27, and the side bottom dividing plate 27 is provided with filter Water plate 26, the top of water curtain plate 24 is provided with water receiving cover 25.
Non-pump type water-screen cabinet 21 is a kind of wet processing apparatus, and tradition water-screen cabinet is different, and it does not has water pump and complexity Tubing, it is to avoid water pump, a pipeline and nozzle susceptible to plugging difficult problem.The wind-force of this equipment utilization air-introduced machine 10 forms negative pressure Water lift forms circulation cascade, is formed mist-like during water pumping of the wind-force.First air containing dust clashes into cascade, wherein Particulate matter and Organic substance soluble in water be retained in water.Then pass through cascade to enter in air water stirring passage, with passage Water smoke produce strong stirring mixing, particulate matter is cleaned in water completely, pulls solid residue out dragging for concentrate at slag.One After dividing water to follow air-flow entrance plenum chamber, airflow fence being separated from water by air, the gas after process passes water filter plate 26, by drawing Subsequent processing device guided to by blower fan 10;And the water separated flows into tank 28 after water receiving cover 25 collects, circulate and so forth, Can effectively remove the granule harmful components in air.Equipment running process constantly there is new water add water through automatic water-replenishing device Case, the water in water tank can be repeatedly circulated, and is not required to discharge.Particulate burning purifying efficiency can reach >=98%.
Photoassisted oxidation technique uses OH to be oxidizing agent solution.UV/ OH oxidation technology is to send out at field of Environment Protection in recent years The advanced oxidation processes that exhibition is got up, this technology is polluted by producing hydroxyl radical free radical (OH) oxidative degradation of strong oxidizing property Thing.Wherein metal ion is substantially reduced as catalyst, the activation energy making OH decompose, the introducing of ultraviolet light (UV), significantly carries The oxidation effectiveness of high oxidation reagent.UV/ OH technology is the most highly developed with application in the research of water treatment field, but relevant utilization The research of UV/ OH technical finesse VOCs is less.Multinomial research finds, the introducing of ultraviolet light can strengthen the degraded of VOCs.Light Helping Fenton's reaction process to include Fenton's reaction and light-Fenton's reaction, reaction equation is as follows:
Fe2++H2O2 (Fe3++OH-+ OH (Fenton's reaction)
FeIIIOH2+ (Fe2++ OH (light-Fenton's reaction)
Organic pollution, under the effect of OH, changes into intermediate product, then is degraded to mineralization product (such as CO2, water).
Such as, Tokumura etc. utilizes ultraviolet light assisted oxidation catalytic reaction degraded toluene, gives kinetics mould Type, analyzes toluene and the dynamic change of carbon dioxide in gas, liquid, the effect of toluene in photoassisted oxidation reaction degraded gas. Having investigated the impact on degraded toluene of the initial pH of oxidising agent solution, oxidant concentration and toluene initial concentration, result shows, Ultraviolet lighting accelerates the generation of hydroxyl radical free radical, significantly improves the clearance of toluene in gas;Ultraviolet light, oxidant are one Under conditions of Ding Liang, toluene removal rate is the highest.Example: as toluene initial concentration 260mg/m3, clearance can reach 98%; Intermediate product outside toluene experiment is not detected by CO2 in photoassisted oxidation catalytic reaction degraded gas, CO2 productivity analysis shows The toluene removed is completely converted into CO2.Native system first passes through non-pump type water-screen cabinet and dusty gas is carried out preliminary treatment, the most again Being further processed by photoassisted oxidation tower, effectively can purify dusty gas, treatment effect is preferable.
Above an embodiment of the present utility model is described in detail, but described content is the most of the present utility model Preferred embodiment, it is impossible to be considered for limiting practical range of the present utility model.All made according to this utility model application range Impartial change and improvement etc., within all should still belonging to patent covering scope of the present utility model.
