Description

A kind of acid mist purifying tower

Technical field

The utility model relates to a kind of equipment for treating industrial waste gas, and the especially processing to sour gas and retracting device, belongs to exhaust-gas treatment and environmental technology field.

Background technology

Along with industrialized degree is more and more higher, the exhaust emission problem of bringing thus also more and more causes people's attention, these harmful gases must just can be discharged in atmosphere after strict processing reaches atmosphere comprehensive discharge standard, at present, at chemical industry, electroplate in the acid cleaning process of producing and process and have a large amount of acid mist γ-ray emissions, contaminated air, unhealthful, mainly to adopt acid mist purifying tower to process acid mist gas at present, the filler bracket of existing acid mist purifying tower is to adopt 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 utility model is exactly the deficiency that will overcome existing acid mist purifying tower, and a kind of novel acid mist purifying tower is provided, and adopts this molecular material to prevent the corrosion to 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.

Utility model content

The technical problems to be solved in the utility model is: a kind of novel acid mist purifying tower is provided, this purifying column is provided with the adsorption layer of pernicious gas by below, gas outlet, can again 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, dividing plate is set can make waste gas rise, avoid the pollution to dosing tank, facilitated operation, saved the unnecessary cost causing due to pollution.

In order to address the above problem, the utility model is realized by following 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, demister composition.Tower body is the hollow-core construction that polyvinyl chloride or polypropylene material form; 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 the hopper top 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, liquid is transported in tower body, waste gas is entered in tower body by air inlet, through the absorption of liquid in packing layer, and the liquid of the spray of spray head, final process demister is discharged by gas outlet, has reached the object of removing the acid mist in waste gas.

Fluid-through tube is equipped with at dividing plate center, is used for carrying the liquid that has absorbed acid mist to enter hopper, and partition shape is tapered.

Packing 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.

Adopted after such scheme, the beneficial effects of the utility model are:

Industrial waste gas enters into tower body from air inlet, first pass through lower packing layer, react with alkaline absorption solution wherein and generate saline solution, incomplete absorbed acid mist gas continues to rise, absorb chemical reaction with the practicing liquid of lower spray head spray, if be not also absorbed completely, continue to rise, packing layer, upper spray head in process, clean gas through multistep treatment enters atmosphere from the exhaust outlet of upper end, thereby has reached the effect that purifies acid mist gas.

Therefore, the utility model compared with existing acid mist purifying tower, outstanding being a little having: the packing layer of the two-layer or multilayer of (1) process, increased the area of gas liquid reaction, the efficiency of absorption is higher, better effects if; (2) adopt polyvinyl chloride or glass-reinforced plastic material, alleviated deadweight, greatly improved the corrosion resistance of equipment.

Accompanying drawing explanation

Accompanying drawing 1 is structural representation of the present utility model.

In accompanying drawing: 1. tower body; 2. packing layer; 3. hopper; 4. spray head; 5. demister; 6. dividing plate; 7. fluid-through tube; 8. liquid level gauge; 9. dosing water supply tank; 10. centrifugal pump; 11. valves; 12. Pressure gauges; 13. air inlets; 14. gas outlets; 15. manholes; 16. brackets.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further.As shown in Figure 1, first determine and need the air quantity of purification in allowed limits, adjust valve 11 to control the spray flux of spray head 4, then by dosing water supply tank 9, add purification neutralizer, start centrifugal pump 10, make upper and lower spray head start liquid-spraying purified liquid, by air inlet 13, pass into the gas containing acid mist to be clean again, the acid mist gas that enters tower body 1 from bottom first by the filtration of packing layer 2 absorb, up carry out haptoreaction with the scavenging solution of spray head spray again, because acid mist gas and scavenging solution are reverse flow, increased the response area of contact, gas-liquid is fully contacted and neutralization reaction occurs with it, acid mist gas after purification travels up to packing layer, continue to react with the scavenging solution of upper spray head spray, through purifying for the second time, after twice purification, clean gas is drained in atmosphere by gas outlet 14 by the processing of demister, the material that reaction generates flows into the hopper 3 at the bottom of tower with neutralizer, and carry out at any time dosing to guarantee recycling of scavenging solution by dosing water supply tank.
