When the implementation of the utility model is carried out, the utility model can carry out a secondary purifying method pf the water bath and the water spraying to the waste gas, and thus, the effect on purification treatment is enhanced. The utility model has the advantages of simple structure and low cost, and the utility model is suitable for popularization and application.

Description

Catalytic converter

The utility model relates to environmental protection equipment, especially relates to a kind of emission-control equipment.

It is the pith of environmental protection cause that waste gas purification is administered.Along with improving constantly of people's living standard, catering industry such as restaurant, restaurant increase rapidly, and the oil smoke gas that the kitchen produces is discharged in the atmosphere in a large number, cause the severe contamination of atmosphere and environment, influenced people's normal life and healthy, therefore, need carry out purified treatment waste gas.Existing emission-control equipment adopts single water spray process, in emission-control equipment, be provided with water spray system, the waste gas that enters from air inlet pipe the emission-control equipment is carried out the processing of water spray, impurities in waste gas is sticked by shower water, thereby separate, the waste gas after will handling then is discharged in the atmosphere.But owing to only carry out single water spray cleaning, and the time of contact of shower water and waste gas is shorter, contacts fully inadequately, and clean-up effect is often not ideal enough.

The purpose of this utility model is to overcome the deficiencies in the prior art part, and provides a kind of clean-up effect better catalytic converter.

The purpose of this utility model is to realize like this, a kind of catalytic converter, comprise housing, outside housing, stretch into the water collector that air inlet pipe, its spray head in the housing is arranged on the water spray system in the housing and is arranged on the housing internal upper part, it is characterized in that, also comprise the water-bath device that is arranged on bottom in the housing, the gas outlet of described air inlet pipe is immersed under the liquid level of water-bath device.

Implement catalytic converter of the present utility model, owing to increased the water-bath device, can implement the secondary purification method to waste gas, that is, the waste gas that enters catalytic converter from air inlet pipe at first passes through the water-bath device, and the liquid in waste gas and the water-bath device is reacted; Carry out the water spray by water spray system again and handle, thereby improved the purified treatment effect greatly.The utility model is simple in structure, and is with low cost, is suitable for applying.

Below in conjunction with drawings and Examples, further specify the structure and the characteristics of the utility model catalytic converter, in the accompanying drawing:

Fig. 1 is the structural representation of an embodiment of the utility model catalytic converter;

Fig. 2 is the A-A direction cutaway view of catalytic converter shown in Figure 1.

As shown in Figure 1, in an embodiment of the present utility model, catalytic converter comprises upper shell 101, lower house 102, base 2, air inlet pipe 3, water spray system, water-bath device and water collector 6.

Wherein, it between the upper and lower casing dismountable connection, fixedly connected as passing through the some screws of flange 104 usefulness, spacing between these screws equates, like this, because exhaust outlet 103 is arranged on the top of upper shell 101, can by the screw that transposing matches up and down adjust exhaust outlet 103 towards, to adapt to the needs of different occasions.Upper shell 101 and lower house 102 can adopt Anti-corrosion glass steel, carbon steel or stainless steel material to make.

Bottom in the upper shell 101 is provided with water collector 6, and water collector 6 is made by the two S shape glass-reinforced plastic materials of plurality of rows, sticks the inwall that is fixed on housing with the plexiglas fiber cloth.Air inlet pipe 3, water spray system and water-bath device all are arranged under the water collector 6.Air inlet pipe 3 extend into outside housing in the housing, and its air inlet 301 links to each other with the blower fan of outside, and waste gas is entered in the liquid by air inlet pipe 3 by air inlet 301.The gas outlet of air inlet pipe 3 is provided with diffusion shell 302, and the outlet of diffusion shell 302 is immersed under the liquid level of water-bath device.Be provided with cone structure 303 in the diffusion shell 302, cone structure 303 is by fixed head 304 and diffusion shell 302 fixing (as shown in Figure 2), and the effect of cone structure 303 is to increase dynamic pressure, accelerates the waste gas flow velocity, promotes that gas-liquid merges fast.Water spray system comprises spray head 401, water-supply-pipe 402, water inlet pipe 403, water intaking valve 404, circulating pump 405, filter 406, circulating water pipe 407, circulating-water valve 408, evacuated tube 409, exhaust-valve 410 and delivery port 411, wherein, spray head 401 is arranged in the housing 102, and other all is arranged on outside the housing.The water-bath device comprises water-bath liquid 501 and the overflow pipe 502 that contains in lower house 102.The spray head 401 of water spray system is arranged on the liquid level of water-bath device.

When purifying duty, water intaking valve 404 and exhaust-valve 410 are closed, circulating-water valve 408 is opened, under the drive of circulating pump 405, liquid is sprayed out by spray head 401, forms water-bath liquid 501 in lower house 102, water-bath liquid 501 is flowed out by delivery port 411, through filter 406 and circulating pump 405, by spray head 401 ejections, form the working fluid circulation by circulating water pipe 407 again.At different waste gas, can in circulating fluid, add different medicaments, thereby obtain better clean-up effect.Overflow pipe 502 is a U-shaped tubular construction, and the one end mouth of pipe is arranged in the housing, and the other end reaches outside the housing, forms overflow pipe outlet 504, and when the liquid level of water-bath liquid 501 was higher than overflow pipe and exports 504, water-bath liquid 501 was overflowed by outlet 504.Overflow pipe outlet 504 is provided with swivel joint 503, by swivel joint 503, can regulate the height of outlet 504, thus the liquid level height of control water-bath liquid 501.Water intaking valve 404 can adopt mechanical valve to control moisturizing by hand, or adopts magnetic valve to control automatically.Be provided with water level switch 505 at lower house 102 inwalls, when the liquid level of water-bath liquid 501 was lower than preposition, water level switch 505 actions started electromagnetic water inlet valve 404 and carry out automatic water supplement.When needs, can pass through exhaust-valve 410 and evacuated tube 409 with the circulating fluid emptying.Waste gas enters in the clarifier from air inlet pipe 3, at first carries out first class purification through the water-bath device, carries out secondary purification by water spray system then, carries out gas-liquid separation through water collector 6 again, is discharged into the atmosphere from the exhaust outlet 103 of upper shell 101.
