Abstract

The utility model discloses a wet dust-removing desulphurization device, which is mainly composed of a desulfurization chamber, a dust-removing chamber and a smoke-water separating chamber, a nozzle is arranged in the desulfurization chamber; an inner sleeve and a vertical blocking plate are arranged in the dust-removing chamber; a transverse baffle is arranged on the top; a cyclone is arranged in the smoke-water separating chamber. The device is suitable for purifying the smoke of all boilers.

Description

A kind of wet dust removal desulphurization device

The utility model relates to the boiler accessory machinery field, a kind of specifically wet dedusting, desulfurizer.

China is coal-fired big country, but coal combustion technology is backward, gives off a large amount of sulfur dioxide after the burning, forms acid rain, and is very harmful.Existing boiler wet method dedusting, desulfur technology adopt flue gas to come out from desulfurization chamber more.Direct impingement box bulk absorption liquid level makes absorption liquid catch grit and sulfur dioxide in the flue gas.The most dedusting of this equipment, desulfuration efficiency are not high, and the device fabrication cost is higher, takes up an area of bigger.

The purpose of this utility model provides a kind of dedusting, desulfuration efficiency is higher, cost is lower, takes up an area of few dust-removing desulfurating apparatus.

The technical solution of the utility model is as follows

In desulfurization chamber, adorn one with smoke movement direction absorption liquid nozzle in the same way, flue gas atomizes at injected liquid, in the humidification, also the absorption liquid liquid level that is driven to lower box by jetting fluid at a high speed impacts, flue gas is fully mixed with absorption liquid, micronic dust and sulfur in smoke are absorbed the liquid washing, absorb, flue gas enters dirt pocket subsequently, flue gas is under the effect of the vertical closure plate of the horizontal plate washer at dirt pocket top, middle interior cover and air inlet one side, form vortex flow and rise to air-water separation chamber, in air-water separation chamber,, just discharged through the cyclone dehydration.Cabinet wall lays the heatproof corrosion-inhibiting coating can effectively improve service life of equipment.

The nozzle of assembling in the utility model desulfurization chamber, current tangentially water inlet enter, and are the rotation mode ejection, and jet hole is the hexagonal angle degree.The indoor cyclone bending blade angle of gas-water separation is 120 °.

The utility model has the advantages that volume is little, cost is low, simple to operate, the efficiency of dust collection height, labour intensity reduces when going out to wet ash, and sewage can be recycled.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structure of nozzle schematic diagram;

Fig. 3,4 is the structural representation of dirt pocket;

Fig. 5 is the structural representation of cyclone;

The utility model is made up of desulfurization chamber 1, secondary desulfurization chamber 5, dirt pocket 6, air-water separation chamber 3, Separation of Solid and Liquid chamber 7, cinder chamber 8 as can be known from Fig. 1.In desulfurization chamber, be equipped with one with smoke movement direction absorption liquid nozzle 2 in the same way.The water inlet 10 of nozzle 2 is tangential shape as can be known from Fig. 2, and jet hole 11 is the hexagonal angle degree.Have one at the dirt pocket top as can be known from Fig. 3,4 and leave 90 ° of sector notch transverse baffles 12, there is cover 13 in the cylinder in dirt pocket central authorities, between interior cover and dirt pocket outer wall, a side of air inlet has a vertical closure plate 14.As can be seen from Figure 5, cyclone 4 is made up of 6 blades 15, and blade 15 flexibility are 120 °.

Flue gas flow is through nozzle 2 sprays, mixing in desulfurization chamber 1, impact secondary desulfurization chamber 5 bottoms and absorb liquid level, enter dirt pocket 6, form vortex flow, centrifugal dust-removing, enter air-water separation chamber 3 after, through cyclone 4 centrifugation once more, micronic dust is separated with moisture, and the flue gas of purification is discharged through the gas outlet, top.Dirt pocket bottom and Separation of Solid and Liquid chamber 7 join, and 7 bottoms, Separation of Solid and Liquid chamber and cinder chamber 8 join, and valve 9 is arranged at the cinder chamber bottom.
