Description

Environmental protection gas cleaning dust-precipitator
Technical field:
The utility model relates to a kind of environment protection equipment, is specifically related to utilize Venturi tube to the dust arrester installation that flue gas purifies, and is applied to industries such as electric power, metallurgy, casting, chemical industry, pottery, glass.
Background technology:
In industry production processes such as electric power, metallurgy, casting, chemical industry, pottery, glass, can produce a large amount of harmful smokes, severe contamination surrounding air and environment.The purification of flue gas, be one has key subjects to be solved always.Adopt electric dust suction to handle both at home and abroad at present, its equipment is huge always, and structure is comparatively complicated, and manufacturing, management and maintenance etc. are not very convenient.In recent years, the semidry method dust arrester developed to some extent, though electric relatively dust suction treatment effect will be got well, it still is not very desirable taking off the dirt effect, the bad control of moisture content, and flue dust bonds very seriously on equipment, often needs cleaning, and very inconvenient.
The utility model content:
Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, and a kind of simple in structure, gas cleaning dust-precipitator that dust collection effect is good is provided.
Technical problem of the present utility model is to realize by following technical scheme.It is characterized in that it comprises gas-liquid separator, Wen's deduster and middle collecting tank, described Wen's deduster epimere is provided with water inlet, air inlet, the bottom communicates with middle collecting tank one end, the middle collecting tank other end communicates with the gas-liquid separator bottom, and the gas-liquid separator upper end offers water inlet and exhanst gas outlet.Described Wen's deduster upper end is provided with inner nozzle, and this inner nozzle is the bowl-type nozzle, is communicated with water inlet, and middle standpipe portion position is evenly distributed with 2 or 2 above outer nozzles, and is located at its outer annular distributing pipe and is communicated with.Described gas-liquid separator upper end is evenly distributed with 2 or 2 and is communicated with the water inlet distributing pipe by water pipe with top nozzle, and the centre is provided with drop catcher.Collecting tank is a terraced conical shell in the middle of described, and its side offers discharge outlet and slag-drip opening.
The utility model is interconnected gas-liquid separator, Wen's deduster and middle collecting tank, utilize the interaction of inner and outer nozzles on Wen's deduster simultaneously, in conjunction with the gas-liquid separator secondary spraying flue gas is further purified again, the design of especially annular distributing pipe can guarantee that water sprays on flue gas the dust-collecting efficiency height equably.The utility model structural design is simple, ingenious, and floor space is little, and operation and maintenance is all very convenient, is adapted to purify the dust that wetability is poor, viscosity is big, particle diameter is little.

The specific embodiment:
As shown in Figure 1, the utility model is interconnected by gas-liquid separator 1, Wen's deduster 2 and middle collecting tank 3 to be formed, described Wen's deduster 2 epimeres are provided with air inlet 8 and water inlet 9, the bottom communicates with middle collecting tank 3 one ends, middle collecting tank 3 other ends communicate with gas-liquid separator 1 bottom, and gas-liquid separator 1 upper end offers water inlet 5 and exhanst gas outlet 4.
As shown in Figure 3, end structure is a three-way pipe 27 on described Wen's deduster 2, and air inlet 8 is located at right-hand member, the flue gas that needs to purify enters from here, and left end is provided with water inlet 9, and nozzle 24 joins water inlet 9 by water pipe and within placing in the three-way pipe 27, inner nozzle 24 is bowl-shape, is communicated with water inlet 9; Taper Pipe 26 big ends are connected with three-way pipe 27, and small end connects trunnion 25, and these trunnion 25 other ends and Venturi tube 21 join.In middle trunnion 25 outsides, be provided with annular distributing pipe 22, be evenly distributed with 2 or 2 above outer nozzles 24 on the tube wall, be communicated with annular distributing pipe 22.
As shown in Figure 2, described gas-liquid separator 1 two ends are symmetrical cone barrel, the centre is a body 12, be fixed on the middle collecting tank 3 by bearing 11, its end face is provided with exhanst gas outlet, offers peep hole 16 on the awl tube of upper end, and body 12 upper end edge peripheries are evenly distributed with 2 or 2 with top nozzle 14, be communicated with water inlet distributing pipe 15 by water pipe 17, the centre is provided with drop catcher 13.
As shown in Figure 1, described middle collecting tank 3 is a terraced conical shell, and its side offers discharge outlet 7 and slag-drip opening 6, and waste water and waste residue in the purification process are discharged thus.
The utility model course of work: when flue gas enters in Wen's deduster 2 by air inlet 8, simultaneously it is sprayed by inner nozzle 24 and each outer nozzle 23, the dust-laden air water crosses at a high speed in trunnion 25 positions and mixes the whereabouts, back, enter in the middle collecting tank 3, because this collecting tank is a terraced conical shell, has certain angle of inclination, most of dirt liquid is discharged from discharge outlet 7, flow into circulating water pool, gas after the purification continues upwards to enter in the gas-liquid separator 1, spray by nozzle 14 again, the gas that contains grit is sprayed under the bonding of back to be fallen within on the drop catcher 13, discharge in the collecting tank 3 in the middle of falling within after cohesion, clean air then enters atmosphere by exhanst gas outlet 4, finishes the whole process of gathering dust again.
