Abstract
The utility model discloses a double-tower high-efficient dust removal desulfurization device, which comprises a pretreatment tower and a boiling tower. The pretreatment tower includes a pretreatment chamber and an accumulation chamber, the bottom end of the boiling tower is inserted into the pretreatment tower to penetrate through the pretreatment chamber to the accumulation chamber, a smoke inlet pipe is communicated with the pretreatment chamber, a sprayer arranged inside the pretreatment chamber is externally connected with a desulfurizing solution pipe, a drainage pipe is arranged on the lower side of the accumulation chamber, an overflow pipe is arranged on the upper side of the accumulation chamber, flushing holes are arranged on the connected side walls of the boiling tower and the pretreatment chamber, solution distribution holes are arranged at the bottom of the boiling tower, a demister is arranged at the inner upper end of the boiling tower, and a smoke outlet is arranged on the top of the boiling tower. The double-tower high-efficient dust removal desulfurization device has the advantages that 1, the device is simple, and low in investment and running cost, 2, the device is fine in dust removal and desulfurization effects, dust removal efficiency can reach above 99%, and desulfurization efficiency can reach above 95%, and 3, the device is simple in maintenance, and is convenient in inspection and maintenance of the sprayer so as to avoid blockage of the sprayer.
Description
Technical field
The utility model relates to a kind of coal-fired flue-gas dust-removing and desulfurization device.
Background technology
China is coal-fired big country, the flue dust that annual various coal-burning boilers are discharged reaches tens million of tons, these flue dust without dust-removal and desulfurizing directly are discharged into atmosphere, are the oxysulfides that contains in the main cause that causes atmosphere pollution, particularly coal smoke, after being discharged into atmosphere, combine with vapor in the atmosphere, form acid rain, contaminated soil, water source, having caused serious loss for ecological environment and agricultural production, also is the main cause that causes the building corrosion.At present, the dust-removal and desulfurizing technology to coal smoke mainly contains wet method, semidry method, dry method and sulphur nitrogen combined desulfurization process of cleaning both at home and abroad, and there is following defective in this several method: the one, and complex process equipment, cost is higher; The 2nd, dust-removal and desulfurizing efficient is not high; The 3rd, the operation and maintenance cost height is difficult to promote the use of.
The utility model content
The purpose of this utility model provides that a kind of process equipment is simple, and dust-removal and desulfurizing is effective, the dust-removing desulfurating apparatus of the coal smoke that cost is low.
The purpose of this utility model realizes in the following way: a kind of double tower high-effective dust-removing desulfurizer, comprise pretreater and boiling tower, pretreater is divided into pretreatment chamber and accumulation chambers, the bottom of boiling tower is inserted pretreater and is passed pretreatment chamber to accumulation chambers, smoke-intake pipe is communicated with pretreatment chamber, spray thrower is arranged in the pretreatment chamber, the external doctor solution pipe of spray thrower, the accumulation chambers downside has discharging tube, upside has overflow pipe, has the impulse hole on the sidewall that boiling tower and pretreatment chamber join, and has the separatory hole in the bottom of boiling tower, there is demister the upper end in the boiling tower, and exhaust opening is arranged at the top.
On the preliminary treatment locular wall sleeve pipe is arranged, spray thrower is enclosed within the sleeve pipe, and spray thrower is connected on the doctor solution pipe by infusion tube and fluid-delivery valve.
The utlity model has following beneficial effect, the one, equipment is simple, small investment, operating cost is low; The 2nd, dust-removal and desulfurizing is effective, and efficiency of dust collection can reach more than 99%, and desulfuration efficiency can reach more than 95%; The 3rd, safeguard and simply conveniently spray equipment checked maintenance that the situation of avoiding spray equipment to stop up takes place.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
As shown in Figure 1, a kind of double tower high-effective dust-removing desulfurizer, comprise pretreater 1 and boiling tower 8, pretreater 1 is divided into pretreatment chamber 2 and accumulation chambers 3, the bottom of boiling tower 8 is inserted pretreater 1 and is passed pretreatment chamber 2 to accumulation chambers 3, smoke-intake pipe 4 is communicated with pretreatment chamber 2, spray thrower 5 is arranged in the pretreatment chamber 2, spray thrower 5 external doctor solution pipes 14, accumulation chambers 3 downsides have discharging tube 6, and upside has overflow pipe 7, have impulse hole 11 on the sidewall that boiling tower 8 and pretreatment chamber 2 join, bottom at boiling tower 8 has separatory hole 12, and there is demister 9 upper end in boiling tower 8, and exhaust opening 10 is arranged at the top; On pretreatment chamber's 2 walls sleeve pipe 13 is arranged, spray thrower 5 is enclosed within the sleeve pipe 13, and spray thrower 5 is connected on the doctor solution pipe 14 by infusion tube 15 and fluid-delivery valve 16.
