Abstract
The invention relates to a desulfurizing tower. The desulfurizing tower comprises a tower body, wherein a demister is arranged on the inner wall of the tower body, spraying pipes are arranged above and below the demister, the demister is arranged obliquely, the spraying pipes and the demister are arranged in parallel, the demister comprises a plurality of baffle plates, the cross section of the baffle plate is of a horizontal s shape, a first groove with an upward opening and a second groove with a downward opening are formed on the baffle plate, and the second groove of the previous baffle plate is inserted into the first groove of the latter baffle plate. The direction of air flows is changed twice with 180 degrees when air flows pass through the demister, and small droplets contained in the air flows are removed basically; and besides, the demister is arranged obliquely, after the spraying pipe is washed, dirt can flow out through the lower end, and sedimentation and blockage phenomena cannot happen easily.
Description
Technical field
The present invention relates to technical field of desulfurization, especially relate to a kind of high demisting efficiency and can not occur block desulfurizing tower.
Background technology
In wet desulphurization, absorption tower is in running, easy generation particle diameter is " mist " of 10--60 micron, and " mist ", not only containing moisture, it is also dissolved with sulfuric acid, sulfate, sulfur dioxide etc., also cause staining and heavy corrosion of blower fan, heat exchanger and flue simultaneously, therefore, wet desulfurizing process proposes the requirement of demist to absorption equipment, cleaned gas wanted demist before leaving absorption tower, and in desulfurizing tower, this step of demist all relies on demister to complete.
Demister is divided into baffling half formula and circular pipe type two kinds, the principle of baffle type mist eliminator: when the gas containing mist flows through demister with certain speed, due to the inertial impaction effect of gas, mist and deflection plate collide, and are then attached on deflection plate and form drop.As can be seen here, the orientation angle that demister changes air-flow is larger, except fog effect is better, but once the orientation angle of the change air-flow of demister is larger, also more easily blocks.So in existing desulfurizing tower, be a kind of contradiction between demisting efficiency and blocking.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of desulfurizing tower, demisting efficiency is high and not easily block.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of desulfurizing tower, comprise tower body, described tower body inwall is provided with demister, the both up and down of described demister is provided with shower, described demister is obliquely installed, described shower and described demister be arranged in parallel, described demister comprises polylith deflection plate, the cross section of described deflection plate is the s shape of a traverse, described deflection plate forms the second groove that has the first groove towards upper shed and downwardly facing opening, second groove of previous described deflection plate inserts in the first groove of a rear deflection plate.Air-flow through demister, its direction through twice changes of 180 degree, so the droplet contained in air-flow is dispelled totally substantially, simultaneously owing to being obliquely installed, after shower rinses, dirt can flow out from lower one end, is also less likely to occur alluvial blocking.
In technique scheme, preferably, each turning point of described deflection plate is right angle.
In technique scheme, preferably, the angle between described demister and horizontal plane is 5 ° to 10 °.
The present invention compared with prior art, there is following beneficial effect: air-flow is through demister, its direction is through twice changes of 180 degree, so the droplet contained in air-flow is dispelled totally substantially, simultaneously owing to being obliquely installed, after shower rinses, dirt can flow out from lower one end, is also less likely to occur alluvial blocking.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Fig. 2 is the schematic perspective view of demister.
Fig. 3 is the schematic diagram that air-flow flows in demister.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail.
See Fig. 1 and Fig. 2: a kind of desulfurizing tower, comprise tower body 3, described tower body 3 inwall is provided with demister 1, and described demister 2 is obliquely installed, and the included angle A between described demister and horizontal plane is 5 ° to 10 °.Described demister 1 comprises polylith deflection plate 11, and the cross section of described deflection plate 11 is the s shape of a traverse, and each turning point of deflection plate 11 is right angle.Described deflection plate 11 forms the second groove 1b that has the first groove 1a towards upper shed and downwardly facing opening, and the second groove 1b of previous described deflection plate 11 inserts in the first groove 1a of a rear deflection plate 11.Two end measures of every block deflection plate 11 are fixed on tower body 3 inwall, and one end that deflection plate 11 is lower and tower body 3 inwall have certain gap 1c, and this gap 1c is exactly the outlet of the first groove 1a.
The both up and down of described demister 1 is provided with shower 2, and described shower 2 be arranged in parallel with described demister 1, and shower 2 is provided with multiple shower nozzle 21, shower nozzle 21 is for the water to demister 2 jet douche.
See Fig. 3, air-flow from demister 1 through out-of-date, through the turnover of deflection plate twice 180 °, so the droplet contained in air-flow is dispelled totally substantially.When shower rinses simultaneously, the dirt in groove 1b can fall due to gravity, and the dirt in groove 1a along with groove 1a is toward dirty, can flow out from the gap between deflection plate 11 and the inwall of tower body 1.
