Abstract
The utility model relates to a boiler flue gas desulfurizer with a conical tower bottom, which belongs to the technical field of environment protection. The desulfurizer is shaped like a tower, a demister and spraying layers are sequentially arranged from a tower top down in the tower body, and the lower part of the tower body is a liquid storage tank. The wall of the tower body between the spraying layers and the liquid storage tank is provided with a flue gas inlet; and an upper aerated conduit and a lower aerated conduit are arranged in the liquid storage tank. The desulfurizer has the advantages that: the tower bottom is conical, the disturbance-generating system in the conventional structure is dispensed with, and therefore the abrasion of a circulating pump is decreased. After slurry is saturated in the process of absorption, (NH4)2SO4 crystals are constantly precipitated, produced particles suspended in absorption solution constantly grow up as well, settle to the conical part after growing up to a certain degree, and are transferred into a swirler by a discharge pump, consequently, large hard particles do not exist at the inlet of the circulating pump, and thereby the abrasion of the circulating pump is decreased.
Description
Technical field
The utility model is the boiler flue gas desulfurization device of taper at the bottom of relating to a kind of tower, belongs to environmental protection technical field.
Background technology
Ammonia process of desulfurization major part is to continue to use sulfur removal technologies such as calcium method, magnesium method at present, only considers desulfurization, does not consider rate of recovery problem, and therefore, the ammonia recovery problem all fails thoroughly to solve.If ammonia recovery and product (NH
4)
2SO
4The rate of recovery reaches more than 98%, and the ammonia process of desulfurization is exactly present best sulfur removal technology.
Though ammonia process and calcium method, magnesium method all are the wet desulfurizing process of acid-base neutralization, ammonia process and calcium method, magnesium method are that there is a big difference.The solubility of the product ammonium sulfate of the ammonia process of desulfurization is very big, and in the time of 60 ℃, solubility is 84g/100gH
2Therefore O can not outwards discharge recovery liquid, and will control systematic water balance well, otherwise can have a strong impact on the rate of recovery.And the desulfurization of calcium method is because CaSO
4Solubility very little, do not need the water balance of strict control system, also can obtain product, and products C aSO
4Value low, so product recovery rate is not very important.
Summary of the invention
The purpose of this utility model is to propose at the bottom of a kind of tower to be the boiler flue gas desulfurization device of taper, to change the structure of existing boiler flue gas desulfurization device, with the rate of recovery of useful products in the raising boiler smoke, and reduces the pollution of boiler smoke to environment.
The boiler flue gas desulfurization device that at the bottom of the tower that the utility model proposes is taper is a turriform, is provided with demister and spraying layer from top to bottom successively from cat head in the tower body, and the bottom is a liquid storage tank in the tower body; Tower body wall between described spraying layer and the liquid storage tank is provided with smoke inlet; Be provided with aeration tube and following aeration tube in the liquid storage tank.
Be the boiler flue gas desulfurization device of taper at the bottom of the tower that the utility model proposes, its advantage is to adopt taper at the bottom of tower, has cancelled the system that produces disturbance in the existing structure, has therefore reduced the wearing and tearing of circulating pump.In absorption process, after slurries are saturated, (NH

2SO
4Crystallization is constantly separated out, and the particle of generation is suspended in the absorption liquid also constantly grows up, and grows up to a certain degree when particle, just is deposited to the tapering, sends into cyclone through excavationg pump, so the not big solid particle in pump entry place, thereby has reduced the wearing and tearing of circulating pump.
Description of drawings
Fig. 1 is to be the structural representation of the boiler flue gas desulfurization device of taper at the bottom of the tower that the utility model proposes.
Among Fig. 1, the 1st, cat head, the 2nd, demister, the 3rd, spraying layer, the 4th, smoke inlet, the 5th, last aeration tube, the 6th, following aeration tube, the 7th, taphole, the 8th, liquid storage tank.Arrow is the flue gas traffic direction among the figure.
The specific embodiment
At the bottom of the tower that the utility model proposes be taper boiler flue gas desulfurization device structure as shown in Figure 1, this desulfurizer is a turriform, is provided with demister 2 and spraying layer 3 from top to bottom successively from cat head 1 in the tower body, the bottom is a liquid storage tank 8 in the tower body.Tower body wall between spraying layer 3 and the liquid storage tank 8 is provided with smoke inlet 4.Be provided with aeration tube 5 and following aeration tube 6 in the liquid storage tank 8.
Introduce the operation principle and the course of work of the utility model desulfurizer in detail below in conjunction with accompanying drawing:
The flue gas that boiler induced-draft fan (or desulfurization booster fan) comes, after being cooled to about 100 ℃, heat exchange enters desulfurizing tower from smoke inlet 4, and three layers of spray in spraying layer 3 from the bottom to top, the ammoniacal liquor and the sulfur in smoke that spray in the shower nozzle of spraying layer react, and generate ammonium sulfite.Flue gas after the desulfurization through demister 2 demists after cat head 1 enters smoke stack emission.The spraying layer below absorbs the ammonium sulfite that forms and be oxidized to ammonium sulfate in the liquid storage tank of bottom, absorption tower.
Taper is adopted in the bottom of the liquid storage tank 8 at the bottom of the flue gas desulfurization Tata of the present utility model, and cancelled perturbed system in the existing desulfurizing tower, but in liquid storage tank 8, set up aeration tube 5 and following aeration tube 6, to strengthen the oxidation reaction that sulfite oxidation becomes ammonium sulfate.After solution is saturated, (the NH in the solution
4)
2SO
4Crystallization is constantly separated out, and the particle of generation is suspended in the absorption liquid also constantly grows up, and grows up to a certain degree when particle, just is deposited to the tapering, sends through excavationg pump.Ammonia spray liquor in the spraying layer 3 is by the effect of circulating pump, constantly circulates with solution in the liquid storage tank 8, because the bulky grain in the solution has been deposited to the tapering, reduced the wearing and tearing of circulating pump.In absorption process,, so the not big solid particle in pump entry place, make the also not big solid particle in porch of circulating pump, thereby reduced the wearing and tearing of circulating pump.
Among the embodiment of the present utility model, the used fog that removes is developed limited formula production by Beijing epoch safe section purification techniques.The product that also can use Wuhan Keep-Hope Environmental Protection Co., Ltd. to produce.
