Without pump water curtain purifier
Technical field
The utility model belongs to the absorbing and purifying device of coating cloud, dust and waste gas, is specifically related to a kind of purifier that can produce circulation water curtain without the need to water pump.
Background technology
Industrial waste gas particularly sprays paint and purified treatment many employings wet-treating of dust, and the fine and closely woven water smoke produced by water pump can effectively realize giving a dinner of welcome, desulfurization or purification operation.Current wet purification method has been widely used in the purification of the industries such as machinery, electronics, metallurgy, chemical industry and pharmacy.
For realizing fully mixing of waste gas and water smoke, and absorb the abundant atomization of water, after current wet cleaning facility generally adopts and waste gas is applied power with water reverse movement or together with spray to be formed and be atomized gas-water mixture, then carry out gas, water be separated, realize the purification of waste gas.This purification facility, because the acidification of waste gas and corrosivity, can cause the corrosion of air pump or water pump, reduces the service life of air pump or water pump, adds purification cost.
Our unit technical staff several years ago once invented a kind of without pump water curtain purifier, solved the problems referred to above.But the structural design of this device also exists certain defect, and structure slightly dislikes complicated, and the formation of water curtain and water circulation do not reach desirable degree, still need to make improvements again.

Water leads to side plate bottom and is separated by cyclic water tank, is divided into linker structure.
Water curtain plate tilts to air inlet from top to bottom.
Be equipped with overflow groove bottom water falling pipe, overflow groove is arranged on the upper end of water curtain plate.
Deflector is provided with, by water water conservancy diversion in water falling pipe in the middle of plenum chamber.
The water fender being provided with an oblique arrangement between gas outlet is led in plenum chamber.
The below of gas outlet is provided with waste gas purification apparatus, is communicated between plenum chamber with gas outlet by waste gas purification apparatus.
The beneficial effects of the utility model are:
Structure simple designs is reasonable, without the need to using water pump, only relying on the blower fan at gas outlet place to form water curtain capable of circulation and carrying out purified treatment to waste gas.It can realize the abundant purification of waste gas and recycling of purifying waste water.Purifier consumed energy of the present utility model is low, and purification efficiency is high, and treating capacity is large.

Detailed description of the invention
As shown in Figure 1, a kind of without pump water curtain purifier, be encapsulated in a rectangle box body 1.The positive basifacial of box body 1 arranges air inlet, and top sets out gas port 12.The box body 1 at gas outlet 12 place is provided with blower fan (not drawing in figure).Cyclic water tank 2 is provided with bottom box body 1.Cyclic water tank 2 is equipped with one block of vertical water and leads to side plate 7, water leads to bottom side plate 7 and is separated by cyclic water tank 2, be divided into linker structure, water leads to side plate 7 top and the latter half of box body 1 is separated into two spaces, an inlet plenum 13 being water and leading between side plate 7 and air inlet, another is the gas-water channel 8 that water leads between side plate 7 and box body 1 back side.Lead on side plate 7 at water and be positioned at inlet plenum 13, arrange one from top to bottom to the water curtain plate 3 that air inlet tilts, gas-water channel 8 and air inlet separate by water curtain plate 3.The top leading to side plate 7 at water is provided with plenum chamber 6.Bottom plenum chamber 6, arrange the water falling pipe 5 that is passed into inlet plenum 13, be equipped with overflow groove 4 bottom water falling pipe 5, overflow groove 4 is arranged on the upper end of water curtain plate 3.Deflector 9 is provided with in the middle of plenum chamber 6, can by water water conservancy diversion in water falling pipe 5.The water fender 10 being provided with an oblique arrangement is led between gas outlet 12 in plenum chamber 6.The below of gas outlet 12 is provided with waste gas purification apparatus 11, is communicated between plenum chamber 6 with gas outlet 12 by waste gas purification apparatus 11.
Purification process of the present utility model is:
Without pump water curtain purifier, the negative pressure utilizing the blower fan at gas outlet 12 place to produce, rises to plenum chamber 6 the water extraction in cyclic water tank 2, flows into overflow groove 4 after collecting through downpipe 5, then overflows to water curtain plate 3 from overflow groove 4 and form water curtain.Now, gas containing coating cloud, dust and waste gas enters inlet plenum 13 under the effect of air current composition, first contact with water curtain plate 3, part bulky grain pollutant is retained in water, gas-water channel 8 and air inlet separate by water curtain plate 3, gas leads to by water the gas-water channel 8 that side plate 7 forms with box body 1 by entering through water curtain after water curtain plate 3, and the water of gas and gas-water channel 8 li is uniformly mixed, and particle is settled down in cyclic water tank 2.Part water is followed after air current composition enters plenum chamber 6 and is made gas-water separation through deflector 9, and gas after treatment through water fender 10, then enters waste gas purification apparatus 11 and adsorbs, and is discharged into air from gas outlet 12 by exhaust blower.
The reasonable in design of this nothing pump water curtain purifier, does not need to use water pump, only relies on the exhausting be connected with gas outlet 12 to arrange, forms water curtain capable of circulation, realize the abundant purification of coating cloud, dust and waste gas and recycling of water.
This nothing pump water-curtain exhaust gas cleaner is the pipe-line system of a kind of wet processing apparatus, dry pump and complexity, avoids water pump, pipeline blocks up a cold difficult problem.This equipment adopts air induction water lift to form circulation water curtain.First air containing dust clashes into water curtain, and particulate matter is wherein retained in water.Then enter gas-water channel through water curtain, produce strong mixing with the water in passage.After entering plenum chamber, flow velocity reduces suddenly, and the gas after process, by water fender, is discharged in air; And separated water flows into the water stream channel bottom collection chamber after collection chamber collects, flowing to overflow groove from water stream channel, overflowing on water curtain plate by opening at overflow groove, the harmful components in waste gas are removed in circulation and so forth.
The utility model waste gas to be clean can enter in gas-water channel through water curtain under this effect without the blower fan of bleeding at the gas outlet place of pump water-curtain exhaust gas cleaner, form air-water mixture, fully contact and absorption can be there is in the process of the rising of this air-water mixture, realize the purified treatment of waste gas.For increasing clean-up effect, cascade filtration unit can be set up in this gas-water channel, realize preferably atomizing effect, through purification absorb air-water mixture with after enter collection chamber through the top of gas-water channel, enter the air-water mixture after collection chamber because space and passage increase, and flowing velocity reduces, start to realize water under the double action of import department's separating plate simultaneously, gas is separated, water after separation returns overflow groove after the water stream channel of collection chamber bottom, thus the waste gas entered by air inlet is adsorbed and absorbs the soluble gas in waste gas, preliminary purification is realized at this place, water simultaneously after this separation recycles by entering water tank after water curtain.Gas after separation is by being discharged by gas outlet by the top of collection chamber after active carbon catalytic converter.
