Embodiment Construction
[0023] Such as figure 1 , 2 , 3, the dust removal and desulfurization equipment is composed of a desulfurization dust collector 4 and a centrifugal demister 6. The flue gas inlet 11 of the desulfurization dust collector is connected to the flue gas outlet of the boiler through pipes, and the flue gas outlet 12 of the desulfurization dust collector is connected to the flue gas inlet 1 of the centrifugal demister.
[0024] The two groups of boiler desulfurization and dust removal systems can be combined in parallel, and the air intake end is connected to the boiler flue gas outlet through the three-way smoke box 10 .
[0025] Such as Figure 4 As shown, there are two groups of impulsive vane groups and reflective vane groups at the liquid surface of the desulfurization dust collector. The impulsive guide vane group is composed of upper and lower arc-shaped impulsive vanes 15 and 14. The two vanes are arranged opposite to each other. An "S"-shaped flue gas channel is formed. T...

Abstract
The invention is a boiler wet-desulfurizing dust cleaning system, including desulfurizing cleaner, desulfurizer maker and water circulating device. Its desulfurizing dust cleaning device is composed of desulfurizing cleaner and centrifugal fogbroom, there are impact guide vane group and reflecting vane group set in the surface position in the desulfurizing cleaner, it adopts particular cyclonic pulverization, thus the contacting time of the gas and liquid is long, their mixing is full, their reaction is thorough and the desulfurizing efficiency can reach 75-85%; it adopts two level dust cleaning, thus its synthetical dust cleaning efficiency can reach 99%. Its desulfurizer maker is composed of desulfurizer storehouse, spiral gauge feeder and hydro-agitator pulping machine; it adopts the closed-loop water circulation; and adopts the wet dust discharging without secondary pollution. It is applied to power station boiler and industrial boiler.
Description
technical field [0001] The invention belongs to a boiler desulfurization and dust removal system, in particular to a wet desulfurization and dust removal system for power plant boilers and industrial boilers. Background technique [0002] At present, most of the desulfurization and dust removal methods adopted by power plant boilers are: the flue gas generated by the boiler is first dedusted by an electrostatic precipitator, and then desulfurized by a desulfurization device. The lye is atomized and the SO in the flue gas in the desulfurization tower 2 And other acidic harmful gases to react to achieve the purpose of desulfurization. By designing a reasonable desulfurization tower, controlling the temperature of the flue gas, the amount of lye injected and the degree of atomization, etc., the efficiency of desulfurization can be improved. However, these facilities are complex in structure, expensive, and have high operating costs. [0003] For industrial boilers, most of t...
