Embodiment
The embodiment of the present invention is further described below with reference to accompanying drawing.
As shown in figure 1, funnel-cap type exhaust gas washing tower, including scrubbing tower body 1, the top of scrubbing tower body 1 is provided with exhaust
Air inlet 3 is provided with below mouth 2, scrubbing tower body, along air inlet 3 to the direction of exhaust outlet 2, the inside of scrubbing tower body 1 includes
Waste gas diversion section and waste gas washing section.Waste gas enters inside scrubbing tower body 1 through air inlet 3, and wherein waste gas diversion section plays waste gas
The effect of water conservancy diversion drainage；Waste gas washing section plays waste gas washing, that is, exhaust-gas treatment effect.
Waste gas washing section is provided with emission-control equipment, can set emission-control equipment, example according to the demand of exhaust-gas treatment
Such as, in the present embodiment, from exhaust outlet 2 to the direction of air inlet 3, emission-control equipment includes：Clean pipe 401, demister 402,
Shower 403, Washing spray nozzle 404 and cooling nozzles 405；The bottom of scrubbing tower body 1 is provided with least one leakage fluid dram 406.
As shown in Figures 2 to 5, waste gas diversion section is provided with water conservancy diversion blast cap 5；Water conservancy diversion blast cap 5 includes blast cap body 501；Ring
Around the outer wall of blast cap body 501, multiple guide vanes 502 are arranged at intervals with；Outer wall of the guide vane 502 with respect to blast cap body 501
It is obliquely installed；The top of blast cap body 501 is provided with blast cap 503.
As a kind of embodiment, guide vane 502 is straight panel shape, can also use arc shape board, and multiple guide vanes
502 direction is identical.That is, all guide vanes 502 are tilted facing one direction, have with the flow direction for ensureing waste gas
It is regular.
The installation of guide vane 502 for convenience, devises blade erecting bed 504.Along the outer wall of blast cap body 501, interval
Blade erecting bed 504 is provided with, guide vane 502 is arranged on blade erecting bed 504.The effect of blade erecting bed 504 is to make
The installation of guide vane 502 is more convenient, and it can use various structures, and as a kind of specific implementation, blade erecting bed 504 is phase
To the protrusion structure of the outer wall of blast cap body 501, its upper surface is mounting plane, the end face mounted thereto of guide vane 502.
