Abstract

The utility model discloses a desulphurization smoke and dust collector, in which the coal smog and sulphur dioxide discharged from high-pressure flow and coal burning boiler are fully mixed in a spraying device and then the purified smog is discharged into the atmosphere through a water-gas separation clapboard. Most of smog and sulphur dioxide is dissolved in the water, thus producing smog sediment and generating sulfuric acid in a dust-collecting cylinder; the smog sediment can be discharged from a drain for secondary combustion; and the sulfuric acid reacts with a cast iron ball in the cylinder so as to reduce acidity. The device is especially applicable to boilers of 0.2 to 0.5 tons. A flue of the boiler directly enters a flue header and a high-pressure water pump is driven to continuously work, so that the utility model can make better dedusting and desulphurization for coal burning boilers with outstanding effects.

Description

A kind of desulfurizing dust-eliminating device

The utility model relates to a kind of atmospheric environment protection device.

Because the coal in China reserves are abundant, domestic all trades and professions are generally selected coal-burning boiler for use, it is easy to use, cost is lower, but exist to the dust pollution of atmosphere with owing to sulfur-bearing composition in the coal is higher, enter after the burning in the atmosphere and produce acid rain, having a strong impact on people's normal life and healthy, cyclone dust removal is generally adopted in boiler smoke abatement dedusting at present, multi-tube dusting, bag-type dust, electrostatic precipitation, methods such as expansion chamber dedusting, but be difficult to capture the soot below 10 microns in the flue gas, boiler desulfurization generally select for use lime white or lime stone in the smoke absorption tower its cost cost of several different methods such as desulfurization than higher, use not generally, thereby currently marketed coal-burning boiler more or less all exists the defective to atmosphere pollution.

It is a kind of simple in structure, easy to use that the purpose of this utility model just is to provide, and can carry out dedusting to coal-burning boiler preferably, the device of desulfurization.

The structure of a kind of desulfurizing dust-eliminating device of the utility model is made up of two parts up and down, after utilizing water under high pressure and coal smoke gas fully mixing, separates in the coal smoke gas harmful substance to human body and atmosphere.

Below in conjunction with accompanying drawing a kind of desulfurizing dust-eliminating device of the utility model is described in detail.

Fig. 1 is a kind of desulfurizing dust-eliminating device of the utility model profile.

High-pressure intake pipe (7) is arranged on the top of desulfurizing dust-eliminating device; smoke-intake pipe (6); holding spray apparatus (9) and pipe (8) forms; the high-pressure suction fan that water under high pressure is connected with the coal-burning boiler chimney by high-pressure intake pipe (7) fully mixes down motion with the coal smoke gas that smoke-intake pipe (6) links and pours in the dedusting inner core (3) in holding spray apparatus (9); there is an aqueous vapor to separate dividing plate (5) outside holding spray apparatus (9) and between the dedusting inner core (3); be equipped with above and discharge by pipe (8) again by the hole on the aqueous vapor separation dividing plate (5) a plurality of circular holes separate flue gas in dedusting inner core (3) after; at this moment the size particles in the flue dust is fully mixed with water basically and is poured in the dedusting inner core (3); wherein sulfur dioxide generates sulfuric acid by gas phase or liquid phase reactor, also is punched in the dedusting inner core (3).The lower part structure of desulfurizing dust-eliminating device has dedusting urceolus (2) to be wrapped in outside the dedusting inner core (3), two circles and the joining micro-mesh of dedusting inner core (3) (11) are arranged between dedusting inner core (3) and dedusting urceolus (2), all be with holes on each face of micro-mesh (11), dedusting inner core (3) and micro-mesh (11) part that links also has aperture to link.A filling pipe (10) and overflow pipe (4) are arranged in the upper end of dedusting urceolus (2), filling pipe (10) is a little more than overflow pipe (4), making the water surface remain on overflow pipe (4) locates, in dedusting urceolus (2) lower end an outlet pipe (13) is arranged, its outlet pipe (13) is connected with high-pressure hydraulic pump and is inserted in the high-pressure intake pipe (7), the flue dust that water under high pressure enters by high-pressure intake pipe (7) and smoke-intake pipe (6) fully mixes in holding spray apparatus (9) and down is moved in the dedusting inner core (3), flue gas separates dividing plate (5) by aqueous vapor discharges from pipe (8), reaches discharge standard.The sulfuric acid that water and soot dust granule and sulfur dioxide and water reaction generate is all stayed in the dedusting inner core (3), its bulky grain flue dust will deposit to the bottom, a blow-off pipe (1) is arranged in the bottom of desulfurizing dust-eliminating device, can pass through blow-off pipe (1) through the flue dust of after a while running larger particles discharges, be stirred in and carry out second-time burning in the coal, accomplish not only energy-conservation but also prevent to pollute, when mixing water in dedusting inner core (3) by and the aperture that links of micro-mesh (11) enter and enter into again in the micro-mesh (11) between dedusting urceolus (2) and the dedusting inner core (3), and enter again in the high-pressure intake pipe (7) through high-pressure pump by outlet pipe (13), form the circulation of a relative close type.So just can turn round continuously, in the desulfurizing dust-eliminating device, all scribble the thicker anti-corrosion material of one deck with water and the contacted position of flue gas, can extend working time, the bead of cylinder iron making (12) is housed in micro-mesh (11), it has strengthened the contact area with water, because sulfur dioxide and water reaction generate sulfuric acid, sulfuric acid and iron generation chemical reaction, progressively reduced acidity, thereby the sulfur dioxide that produces behind the coal burning also step-reaction fallen, thereby no longer atmospheric environment is produced acid pollution, played the effect of desulfurization.Thereby a kind of desulfurizing dust-eliminating device is by dedusting inner core (3), dedusting urceolus (2), high-pressure intake pipe (7), smoke-intake pipe (6), hold spray apparatus (9) and separate dividing plate (5) composition with aqueous vapor, its feature is being held spray apparatus (9) and high-pressure intake pipe (7) with one heart, the side and the smoke-intake pipe (6) that hold spray apparatus (9) link, the angle of its tangential direction is 15 °～30 °, holding spray apparatus (9) and the joining bottom of smoke-intake pipe (6), hold spray apparatus (9) two and have tapering, its tapering is up big and down small, this structure has strengthened the well-mixed degree of aqueous vapor, high-pressure hydraulic pump is selected per hour 6～8 cubic metres flow for use, pressure is between 3～4 kilograms every square centimeter, and high-pressure suction fan is per hour selected for use between 2000～4000 cubic metres of air quantity.

After coal smoke gas that the utility model a kind of desulfurizing dust-eliminating device owing to selected for use is discharged in High-Pressure Water and the coal-burning boiler and sulfur dioxide fully mix in holding spray apparatus, and through aqueous vapor separate dividing plate purification after flue gas enter structure in the atmosphere.Its flue dust and the sulfur dioxide overwhelming majority are soluble in water, in the dedusting inner core, produce the flue dust precipitation and generate sulfuric acid, the flue dust post precipitation can be discharged from blow-off pipe and be carried out second-time burning, sulfuric acid reacts with an interior Cast-iron Ball and reduces acidity, and this equipment is adapted to 0.2 ton to 0.5 ton boiler especially and uses.Boiler chimney is inserted in the smoke-intake pipe, start the high-pressure hydraulic pump continuous operation, thereby can carry out dedusting to coal-burning boiler preferably, desulfurization, and have the effect of bright aquatic foods.
