A circulating slurry pool is arranged at the lower section of a tower body, and a washing reaction section is arranged at the upper section; the cross section of the upper section of the tower body of the present invention and the cross section of the lower section are in the shape of a rectangle and are perpendicularly connected into one body; the lower part of the upper section is communicated with a flue gas inlet pipe; spray pipes are distributed at the middle part of upper section. The top of the tower body is connected with a flue gas outlet in the tangential direction; a stirrer and a ventilating pipe are inserted in the circulating slurry pool of the lower section. The present invention avoids the deposition and the scale formation of slurry in the slurry pool at the tower bottom, and further, the desulphurization efficiency of the flue gases is enhanced; the present invention solves the problems to make the present invention meet the requirement that the absorption tower for the wet method desulphurization of the flue gases is convenient for processing and installation.
Description
(1) technical field
The present invention relates to a kind of smoke-gas wet desulfurization device.
(2) background technology
In existing wet desulfurizing process, for removing the sulfur in the flue gas, must build the reaction tower of smoke reaction, flue gas must be sent into reaction tower through flue and carry out desulphurization reaction.Common reaction tower is the steel circle, needs special preprocessing and complicated scene assembling.This device is two sections vertical turriforms of reducing, and its hypomere is the gypsum stock tank, and epimere is the desulphurization reaction section, and the bottom of desulphurization reaction section is communicated with smoke-intake pipe.The turriform design is complicated, and cylindrical tower body processing welding and installation difficulty are bigger, and the Flow Field Distribution and the flow velocity of flue gas are unreasonable in the reaction tower, and the slurries in the tower prime cement pond of reaction tower often have deposition and scale formation, have therefore influenced the desulfurized effect of flue gas.
(3) summary of the invention
The purpose of this invention is to provide a kind of square absorption tower for wet method desulfurization of flue gas, solve the slurries deposition of avoiding tower prime cement pond and the problem of fouling; And solution further improves the problem of smoke desulfurization efficiency; Also solve wet method flue gas-desulfurizing absorption tower and be convenient to the technical problem of processing and installing.
Technical scheme of the present invention: this square absorption tower for wet method desulfurization of flue gas, the tower body hypomere is the circulation stock tank, epimere is the washing reaction section, it is characterized in that: the cross section of tower body epimere and hypomere is rectangle, and vertically be connected as a single entity, the bottom of epimere is communicated with smoke-intake pipe, and the middle part of epimere is furnished with shower, the tangential direction at tower body top connects exhanst gas outlet, inner agitator and the breather pipe of inserting of hypomere circulation stock tank.
The material of above-mentioned tower body is steel or xoncrete structure.
The insertion angle of above-mentioned smoke-intake pipe and desulphurization reaction section is the 5-15 degree.
The inwall of above-mentioned tower body is lined with anticorrosive coat.
Above-mentioned anticorrosive coat is rubber liner layer, resin scale or glass flake inner liner.
The thickness of above-mentioned anticorrosive coat is 2-10mm.
The thickness of above-mentioned anticorrosive coat is 5-8mm.
Above-mentioned shower is one to four layer.
Above-mentioned shower comprises the arm of being responsible for and telling from person in charge both sides, and the arm two ends are erected on the bearing that absorbs on the Tata wall.
The present invention compares the beneficial effect that has with existing conventional art: tower body of the present invention is the steel or the xoncrete structure of square or rectangular, has broken through the intrinsic prejudice that adopts the traditional cylindrical tower body, has obtained beyond thought technique effect.Direct coupled structure has been eliminated the carrier of easy deposition and fouling up and down, and the slurries that solved circulation stock tank at the bottom of the tower are the problem of deposition and fouling easily; The Flow Field Distribution and the flow velocity of flue gas are reasonable in the reaction tower, have improved reaction speed and desulfuration efficiency, and simultaneously, square tube shape tower body simple shape is convenient to processing and installation very much, greatly reduces than traditional absorption tower cost.Can be widely used in lime stone (lime)-gypsum wet or seawater desulfurizing process.The circular tower of the flue gas treating capacity of square absorption tower and traditional steel is suitable, can satisfy from the processing needs of the smoke-gas wet desulfurization of 50MW to 1000MW capacity unit.
