Summary of the invention
Purpose of the present invention be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of contact area large, prevent from stopping up, tail gas absorber applied widely.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of tail gas absorber comprises:
Tower body: comprise the tower main body and be connected to the chimney at tower main body top;
Tower internals: be located in the tower main body, comprise the foam removal net that sets gradually, water mist sprinkling pipe, pump circulated sprinkling pipe, two inner float ball grids and tail gas distributor pipe from top to bottom;
Inner float ball: be located between two inner float ball grids;
Described tail gas absorber is used for comprising H to containing
2S, SO
2, NH
3Or the absorption of phthalic anhydride material tail gas.
The foam that produces in the described foam removal net interception spray-absorption process prevents that foam is together emptying with tail gas.
The shower water entrance that arranges on the described water mist sprinkling Guan Yuta main body connects.
The circulating pump mouth spray that arranges on the described pump circulated sprinkling Guan Yuta main body connects, and this circulating pump mouth spray is connected with the circulated sprinkling pump through pipeline.
Described inner float ball grid adopts metal or nonmetallic materials to make and obtains.
Described tail gas distributor pipe adopts coil pipe perforating structure, is evenly distributed when tail gas is risen.
The gas inlet that arranges on described tail gas distributor pipe and the tower main body is connected.
Described inner float ball is the polytetrafluoroethylene (PTFE) hollow ball.
Tail gas absorber absorption tail gas of the present invention enters at the bottom of by tower, utilize the rising that evenly distributes of tail gas distributor pipe, air-flow swims in the tower body inner float ball, spray water mist is evenly sprayed from cat head, fully contact with the inner float ball surface, utilize the inner float ball surface moisture to need the material absorbing of washing in the uprising gas, flow down immediately, floss hole is discharged at the bottom of the tower, the long-pending increase of relative contact when having utilized inner float ball to roll, taking full advantage of spray water mist, that tail gas is absorbed is more complete, simultaneously because the floating rolling of spheroid and the phenomenon that can not result in blockage.
Compared with prior art, the present invention has the following advantages:
One, contact area is large: compare with the packed tower of fixed head, and large many of the spheroid contact area of floating rolling, the utilization rate of water also just increases immediately.
Two, prevent from stopping up: the ball float coefficient of friction is little among the present invention, and itself can not stick together, and spheroid is floating rolling in tower, also can not cause the obstruction of grid.
Three, applied widely: the present invention is applicable to H
2S, SO
2, NH
3, the absorption of the similar substances such as phthalic anhydride is made corresponding adjustment, applicable more multimedium to absorbing with liquid and ball float.
Four, energy-conservation: because the utilization rate of water is high, spray-water amount relative reduce.
Five, maintenance is convenient: tower internals of the present invention is simple, overhauls more convenient.
