Abstract
An efficient wet-process filtering system comprises a purification tower, a pool and a blower fan; the purification tower is communicated with a cooling channel via an exhaust-gas pipe, and also is communicated with a water inlet pipe and a purification pipe; the pool is provided with a manual dosing tank and a pump, is inside provided with a flashboard and an overflow mouth, is provided with a pollution-discharge clean-thing-discharge port at the bottom, and also is connected with the purification tower via the water inlet pipe; and the blower fan is connected with the purification tower via the purification pipe, and is provided with a gas exhausting chimney. The technical effects comprise that through the water atomization process of a spraying device, exhaust gas is fully contacted with water and has a mass-transfer neutralization reaction, so that exhaust-gas processing is realized, the running operation cost is low, and operation is convenient, content of carbon monoxide and sulfur dioxide is reduced to detection standard requirements, and problems existing in production are effectively solved.
Description
Technical field
The present invention relates to technical field of waste gas treatment, particularly a kind of efficient wet filtration system.
Background technology
In sand casting on casting automatic production line, casting mold after usual cast can produce the waste gas containing toxic gases such as flue dust, tar, carbon monoxide and sulfur dioxide, and these materials can cause fan trouble after entering people's cooling duct with casting mold and there is the hidden danger such as environmental pollution.Therefore, research and develop a set of high-efficiency high-quality, cooling duct waste gas treatment equipment that security performance is good has important practical significance.
Summary of the invention
Technical problem to be solved by this invention is: there is the problems such as environmental pollution, fan trouble is many, poor safety performance, operating cost are high for cooling duct waste gas treatment equipment on casting automatic molding line, provide a kind of efficient wet filtration system.
Technical scheme of the present invention is: a kind of efficient wet filtration system, comprises purifying column, pond and blower fan; Described purifying column is communicated with cooling duct by exhaust piping, and simultaneously with inlet channel with purify pipeline communication; Described pond is provided with artificial dosing tank, water pump, and inside, pond is provided with flashboard and overfall, and bottom is provided with blowdown drain, and described pond also connects purifying column by inlet channel; Described blower fan is connected with purifying column by purification pipeline, and is provided with exhaust chimney.
Described purifying column feed flow spray adopts circle shaped tube type water distribution, and the similar gondola water faucet of shower can be sprayed water to all directions, can make water, gas fully contacts.
Described purifying column selection flower sheet ball formula filler.
Described purifying column adopts and huddles Bauer filler as receipts water demister.
Technique effect of the present invention is: by the water atomization process of spray equipment, neutralization reaction waste gas and aqueous vapor fully being contacted mass transfer occurs and realize exhaust-gas treatment, running cost is low, easy to operate, carbon monoxide, content of sulfur dioxide drop to the standard-required of detection, efficiently solve Problems existing in production.

Detailed description of the invention
As figure, a kind of efficient wet filtration system of the present invention, comprises purifying column, pond and blower fan; Described purifying column is communicated with cooling duct by exhaust piping, and simultaneously with inlet channel with purify pipeline communication; Described pond is provided with artificial dosing tank, water pump, and inside, pond is provided with flashboard and overfall, and bottom is provided with blowdown drain, and described pond also connects purifying column by inlet channel; Described blower fan is connected with purifying column by purification pipeline, and is provided with exhaust chimney.Described purifying column feed flow spray adopts circle shaped tube type water distribution, and the similar gondola water faucet of shower can be sprayed water to all directions, can make water, gas fully contacts.Described purifying column selection flower sheet ball formula filler.Described purifying column adopts and huddles Bauer filler as receipts water demister.
Wet method filtration mainly adopts NaOH solution as cyclic absorption neutralizer.Waste gas first, after cooling duct 1 cools, sucks purifying column 3 by blower fan 13 through exhaust piping 2.To purifying column 3 water delivery, the water of the required spray of each link of purification can be provided by water pump 6.Waste gas through first annular spray to spray region, waste gas is fully contacted with aqueous vapor, there is mass transfer, then waste gas speed change roundabout enter people's second filler spray region, through inverse spray and the reaction of functional stuffing layer of spray, make waste gas obtain the abundant contact of gas-liquid two-phase, mass transfer neutralization reaction occurs.Waste gas treated so slowly enters inverse spray and the reaction of functional stuffing layer of people the 3rd road spray, and through the demist of upper tower body filler demister after making waste gas fully purify, de-liquid process, then enters air via blower fan 13 by exhaust chimney 12.
