Description
Affiliated technical field
The utility model relates to a kind of wet type flue gas desulphurization device, belongs to industrial gas purifying equipment.
Background technology
With coal or oil is boiler, the kiln of fuel, the emptying flue gas of industrial furnace, contains volume of smoke and toxic gas (being mainly sulfur dioxide).The at present industrial equipment that is used for handling above-mentioned flue gas mostly is wet method eddy flow plate technique and spray technique.If adopt wet method eddy flow plate technique, because centrifugal force can not make sulfur in smoke fully mix with water or alkaline solution, so dedusting, desulfurized effect are not good.And if adopt spray technique, water smoke easily to be taken away or evaporate by the flue gas that flows, make flue gas with water serious, the blower fan cisco unity malfunction.
Summary of the invention
In order to overcome existing eddy flow plate technique and the not good shortcoming of spray technique desulfurized effect, the utility model provides a kind of gas liquid reaction even, simple in structure, small investment, the gas purifying equipment that operating cost is low.The technical scheme that its technical problem that solves the utility model adopts is: a kind of wet type flue gas desulphurization device, comprise gas-distributing pipe, scrubbing tower, gas feed, gas vent, feed pipe, drain pipe, described gas-distributing pipe inserts the solution in the scrubbing tower sideling downwards, the central cross-section of gas-distributing pipe becomes 10 °-60 ° angle with horizontal plane, be provided with at least two air dividing plates in the gas-distributing pipe equably, described air dividing plate is divided at least three gas pipelines with gas-distributing pipe, and the end of air dividing plate is connected with water fender upwards, form reservoir between described air dividing plate and the water fender, described reservoir distributes in scrubbing tower from top to bottom, and the reservoir that is positioned at the below also is positioned at after the reservoir simultaneously, and the reservoir that described air dividing plate and water fender form is a bucket shape.During work, if the quantity of reservoir is abundant, then the sectional area of air-flow has obtained effective control, can guarantee that gas liquid reaction evenly, rapidly.Because feed pipe constantly injects recirculated water or circulation lime aqueous solution to reservoir, recirculated water or circulation lime aqueous solution constantly flow into the next stage reservoir along bucket shape liquid storage trough rim again simultaneously, can between two adjacent reservoirs, form one cascade like this, increase the area of gas liquid reaction greatly.In order further to increase the gas liquid reaction area, at least one dividing plate can be set in the middle of the air dividing plate in the described gas-distributing pipe.Carry too many foam secretly for fear of reacted gas, can establish a block demister at the scrubbing tower internal upper part.Above-mentioned gas-distributing pipe and scrubbing tower are rectangular tube, and each gas passage road size that air dividing plate and dividing plate separated like this is even, and are convenient to processing.Each reservoir all is provided with feed pipe and drain pipe in addition, so that the concentration and the flow velocity of control solution.
The beneficial effects of the utility model are to guarantee that gas liquid reaction area and gas liquid reaction evenly, simultaneously rapidly, utilize the ingenious structure of gas-distributing pipe and scrubbing tower itself, the effect that reaches quick, thorough desulfurization or take off dirt.Simple in structure, handling ease, with low cost.
