Description
Technical field
The present invention relates to a kind of equipment for treating industrial waste gas, especially to process and the retracting device of sour gas, belong to exhaust-gas treatment and environmental technology field.
Background technology
Along with industrialized degree is more and more higher, the exhaust pollution problems brought thus also more and more causes the attention of people, these harmful gases have to pass through after strict process reaches air comprehensive discharge standard and just can be discharged in air, at present, at chemical industry, a large amount of acid mist gas is had to produce in the acid cleaning process that plating is produced and processed, contaminated air, unhealthful, acid mist purifying tower is mainly adopted to process acid mist gas at present, the filler bracket of existing acid mist purifying tower adopts steel and iron parts latter made through preservative treatment, its complex manufacturing technology, from great, difficulty is installed, not corrosion-resistant, after using a period of time, corrosion of steel fracture there will be inter collapse, need stop production to overhaul and cause economic loss.
The present invention is exactly the deficiency that will overcome existing acid mist purifying tower, provides a kind of novel acid mist purifying tower, adopts the corrosion that this molecular material prevents tower body and bracket, acid-alkali-corrosive-resisting is strong, and from heavy and light, intensity is high, treatment effect is good, and Operation and Maintenance is acid mist purifying tower simply and easily.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of novel acid mist purifying tower, this purifying column is by being provided with the adsorption layer of pernicious gas below gas outlet, again can purify inner-tower filling material layer and spray equipment purified gas, the purification efficiency of sour gas is improved, and clean-up effect is better simultaneously, purifies more abundant, arranging dividing plate can make waste gas rise, avoid the pollution to dosing tank, facilitate operation, save owing to polluting the unnecessary cost caused.
In order to solve the problem, the present invention is achieved through technology,
A kind of acid mist purifying tower, comprises tower body, packing layer, hopper, centrifugal pump, feed pipe, Pressure gauge, bracket, spray head, dividing plate, fluid-through tube, dosing water supply tank, liquid level gauge, air inlet, gas outlet, sample tap, manhole, and demister forms.Tower body is the hollow-core construction that polyvinyl chloride or polypropylene material are formed; Air inlet is positioned at the lower end of tower body, and gas outlet is positioned at the top of tower body; Hopper is positioned at the bottom of tower body; Packing layer is divided into upper and lower two parts packing layer, respectively by bracket support; Bracket is installed on above the hopper of tower body; Spray head is installed on the end of feed pipe, the top of packing layer; Dividing plate is positioned at the top of hopper, the below of lower packing layer, the side of manhole tower body above the packing layer of upper strata; Demister is installed on the below of gas outlet; Centrifugal pump is installed on hopper outside, by feed pipe by Liquid transfer in tower body, waste gas enters in tower body by air inlet, the absorption of liquid in packing layer, and the liquid of the spray of spray head, eventually pass through demister to be discharged by gas outlet, reach the object of the acid mist removed in waste gas.
Fluid-through tube is equipped with at dividing plate center, is used for carrying the liquid having absorbed acid mist to enter hopper, and partition shape is tapered.
Adsorption layer is acf layer.
The magnitude setting of packing layer and spray head is no less than two-layer.
Hopper scribbles anticorrosive coat, can be polyureas.
After have employed such scheme, the invention has the beneficial effects as follows:
Industrial waste gas enters into tower body from air inlet, first through lower packing layer, react with alkaline absorption solution wherein and generate saline solution, incomplete absorbed acid mist gas then continues to rise, the practicing liquid sprayed with lower spray head carries out absorption chemical reaction, if also do not absorbed completely, continues to rise, through upper packing layer, upper spray head, clean gas through multistep treatment enters air from the exhaust outlet of upper end, thus reaches the effect of purification acid mist gas.
Therefore, the present invention compared with existing acid mist purifying tower, outstanding being a little had: the packing layer of the two-layer or multilayer of (1) process, increases the area of gas liquid reaction, and the efficiency of absorption is higher, better effects if; (2) have employed polyvinyl chloride or glass-reinforced plastic material, alleviate deadweight, substantially increase the corrosion resistance of equipment.
