Description

A kind of spray column for exhaust-gas treatment
Technical field
The utility model relates to emission-control equipment technical fields, and in particular to a kind of spray column for exhaust-gas treatment.
Background technique
Spray column is and the pollutant in gas to be transmitted in liquid using the contact between gas and liquid, then again Clean gas is separated with contaminated liquids, achievees the purpose that peace and quiet air.Exhaust gas is via filled type spray column, using gas-liquid Reverse absorption pattern processing, i.e. liquid from tower top downwards with misty (or droplet) sprays and under.Exhaust gas is then (reverse by tower body Stream) reach the purpose of gas-liquid contact.This processing mode can cool down exhaust gas, conditioning gas and removal particle, at demisting section After reason, it is discharged into atmosphere.Packed tower is the mass transfer apparatus using the filler in tower as contact member between gas-liquid two-phase.Packed tower Tower body is a upright cylinder, and bottom is equipped with supporting plate, filler by huddle or whole block in a manner of be placed on support plate.Filler Top install hold-down grid, blown to prevent being raised air-flow.Liquid is sprayed through liquid distribution trough onto filler from tower top, and edge Filler surface flows down.Gas is sent into from tower bottom, is distributed through distribution device in gas-fluid (minor diameter tower does not set distribution device in gas-fluid generally) Afterwards, the gap for continuing through filler device in adverse current with liquid, in filler surface, gas-liquid two-phase close contact carries out mass transfer. Packed tower, which belongs to, continuously contacts with formula gas-liquid mass transfer (contact) equipment, and two phase compositions are along tower height consecutive variations, under normal operating condition, gas phase For continuous phase, liquid phase is dispersed phase.
Its advantage is that: rinsing type exhaust treatment system, it is cheap, processing method is simple;Occupied area is small;The scope of application Extensively;Spray column resistance is low, well below active carbon exhaust-gas treatment.Energy conservation;Purification efficiency is high.But there are exhaust gas for existing equipment Treatment effeciency is low, and impurity removes halfway problem.
Summary of the invention
The purpose of this utility model is that: a kind of spray column for exhaust-gas treatment is provided, is solved in above-mentioned background technique Mention existing equipment there are exhaust treatment efficiencies low, impurity removes halfway problem.The technical solution adopted in the utility model It is as follows:
A kind of spray column for exhaust-gas treatment, including spray tower body and the water storage being fixedly connected with spray tower body bottom Case, the spray tower body top are provided with gas outlet, are provided with inlet duct, baffling dress in the spray tower body from the bottom to top It sets, the first spray chamber, the second spray chamber and demisting layer, the inlet duct include being symmetrical set in spray tower body lower end Two air inlet pipe and the blast fence that is set between two air inlet pipe, between the blast fence and air inlet pipe there are Gap, the air inlet pipe is through the one side wall for spraying tower body and to be obliquely installed, at the top of first spray chamber and the second spray chamber It is provided with spray piping, bottom is provided with filler device, is provided with several spray heads, the water storage below the spray piping Case upper right side is provided with suction pump, connects between the suction pump and water tank and spray piping for pipeline.
Working principle of the utility model is: exhaust gas enters spray tower body by the inlet duct that spray column lower part is arranged, due to Air inlet pipe be obliquely installed and be provided between two air inlet pipe blast fence, therefore exhaust gas enter air inlet pipe after some solids it is miscellaneous Matter can be precipitated because of self weight, and drop to spray tower bottom along pipeline, and gas is filled because blast fence is gradually increasing into baffling It sets.Gas passes through baffle plate, and partial particulate impurity is trapped and precipitates because of self weight.Gas continues to rise, into the first spray Room, liquid enters spray piping by water tank through suction pump, then is ejected into filler device by spray head, on filler device, gas-liquid Two-phase close contact carries out mass transfer, and subsequent gas enters the second spray chamber and carries out second of mass transfer.After, gas enters demisting Layer removes water mist, and is discharged by gas outlet, and solution existing equipment exhaust treatment efficiency is low, and impurity removes halfway problem.
Further, the baffle means include several baffle plates disposed in parallel.
Further, the top and bottom of the baffle plate are fixed by cross bar respectively, the cross bar and spray tower body inner wall It is fixedly connected.
Further, 6~8 spray heads are provided with below the spray piping, are provided on the spray head with high density state Spray orifice.
Further, the filler device includes supporting plate, packing layer and hold-down grid from the bottom to top.
Further, described filler layer is porous plastics packing layer.
Further, the demisting layer is that polyhedron is molded ball or ceramic raschig rings layer.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
The utility model by the way that two inclined air inlet pipe and blast fence are arranged in the spray column for exhaust-gas treatment, The solid impurity in exhaust gas can be made to precipitate because of self weight;By the way that baffle means are arranged in spray tower body, can make in exhaust gas Partial particulate impurity retained by baffle plate, achieve the purpose that preliminary purification, it is low to solve existing equipment exhaust treatment efficiency, impurity Remove halfway problem.
