Multistage acid mist treatment tower
Technical field
The utility model relates to a kind of acid mist purification apparatus, relates in particular to a kind of multistage efficiently acid mist treatment tower.
Background technology
As everyone knows; In industrial circles such as plating, electrolysis and chemical industry, can produce a large amount of acid mists, enter the atmosphere pollution environment for fear of acid mist; All to carry out purified treatment to the acid mist that produces; Adopt the mode of spray to handle to the processing of acid mist in the domestic big conglomerate at present,, can not dispose acid mist very completely though this method is effective.
The utility model content
The purpose of the utility model is to provide a kind of multistage acid mist treatment tower, its have simple in structure, efficient is high, handle acid mist good purification and safe and reliable characteristics, to solve the problem that acid mist treatment tower exists in the prior art.
For reaching this purpose, the utility model adopts following technical scheme:
A kind of multistage acid mist treatment tower; It comprises purifying column and the catch box that is installed on the purifying column below, and wherein, the bottom of said purifying column connects blast pipe; Corresponding blast pipe sets out gas port in its top; Suction fan is installed at place, said gas outlet, and the installation of the top in the tower of said purifying column filter screen, and the below of said filter screen is parallel and is furnished with the several layers orifice plate; Purification body of the tower between said filter screen and the superiors' orifice plate is installed into water pipe, and the bottom of said purifying column is connected with catch box through woven hose.
Especially, between said catch box and the purifying column pneumatic diaphragm pump is installed, through pneumatic diaphragm pump the liquid in the catch box is pumped to and carry out recycle in the purifying column.
Especially, liquid level gauge is installed in the said catch box, its bottom connects drain pipe, and mounted valve on the drain pipe through the detected liquid level of liquid level gauge, can discharge or recycle through pneumatic diaphragm pump through the valve on the control drain pipe.
Especially, arrange U-tube manometer between said blast pipe and the purifying column.
Especially, mounting filtering device, flowmeter and magnetic valve successively on the said water inlet pipe.
Especially, the number of plies that is provided with of said orifice plate is six layers.
The beneficial effect of the utility model does; Said multistage acid mist treatment tower mainly relies on six layers of orifice plate and one deck filter screen to purify; And through pneumatic diaphragm pump the liquid in the catch box is pumped to and to carry out recycle in the purifying column; Using water wisely, compared with prior art not only simple in structure, be convenient to install; And treatment effeciency is high, good purification, safe and stable equipment operation.
Description of drawings
The structural representation of the multistage acid mist treatment tower that Fig. 1 provides for the utility model specific embodiment 1.
The specific embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and through the specific embodiment.
See also shown in Figure 1, the structural representation of the multistage acid mist treatment tower that Fig. 1 provides for the utility model specific embodiment 1.
In the present embodiment, a kind of multistage acid mist treatment tower comprises purifying column 1 and the catch box 2 that is installed on purifying column 1 below, and the bottom of said purifying column 1 connects blast pipe 3; Arrange U-tube manometer 4 between blast pipe 3 and the purifying column 1, corresponding blast pipe 3 sets out gas port 5 in its top, and suction fan 6 is installed through pipeline by 5 places, said gas outlet; And filter screen 7 is installed at the top in the tower of said purifying column 1, and the below of said filter screen 7 is parallel arrangement six layers of orifice plate 8 are installed, and purifying column 1 body between said filter screen 7 and the superiors' orifice plate is installed into water pipe 11; Mounting filtering device 12, flowmeter 13 and magnetic valve 14 successively on the said water inlet pipe 11; The bottom of said purifying column 1 is connected with catch box 2 through woven hose 9, and pneumatic diaphragm pump 10 is installed between said catch box 2 and the purifying column 1, through pneumatic diaphragm pump 10 liquid in the catch box 2 is pumped to and carries out recycle in the purifying column 1; Using water wisely; Liquid level gauge 15 is installed on the said catch box 2, and its bottom connects drain pipe 16, mounted valve on the drain pipe 16; Through liquid level gauge 15 detected liquid levels, the valve on the control drain pipe 16 discharges or recycles through pneumatic diaphragm pump 10.
During work, the gas that contains acid mist gets into from the blast pipe 3 of purifying column 1, and water inlet pipe 11 begins water filling from cat head, and water flows into lower floor's orifice plate 8 from pipe on the orifice plate 8, flows to bottom web plate so always.Receive the suction of suction fan 6, handle gas and begin to penetrate orifice plate 8 from bottom orifice plate 8 and upwards flow, at this moment the acid mist in the gas contacts with moisture film in the orifice plate 8; Acid mist in the gas is taken away by water like this; Flow into catch box 2, purified gas is discharged by suction fan 6 after filter screen 7 filters.
