It cutting, fluid spills are broken, increase the incorporation time of liquid surface area, reinforce the absorption to harmful material in smoke, reduce operating cost,
Improve nuisance absorption efficiency.
In the present embodiment, spray assemblies 300 are installed in flow channel 110, and spray assemblies 300 are used to be oriented to towards umbrella shape
Cap liquid-spraying purified liquid.Spray assemblies 300 include spray tube 310 and at least one nozzle 320, and it is logical that spray tube 310 stretches into flowing
In road 110, at least one nozzle 320 is mounted on spray tube 310, and at least one nozzle 320 is located in flow channel 110.It can
Choosing, nozzle 320 is provided at least two, and at least two nozzles 320 are intervally arranged along the length direction of spray tube 310.Into one
Step, spray tube 310 includes spray supervisor and at least two spray branch pipes, and at least two spray branch pipe connection sprays are responsible for, until
Few two sprays branch pipe is arranged side by side, and nozzle 320 is equipped on every spray branch pipe.Nozzle 320 is distributed more reasonable, scavenging solution
Area coverage it is big, the contact with flue gas is more abundant, be conducive to harmful substances from flue gases absorption.
At work, kiln gas is under the action of air-introduced machine with per second 17 for desulphurization denitration gas wash tower provided in this embodiment
The speed of -19 meters or so of rice enters desulphurization and denitration, dedusting absorption tower 100, and bulk velocity of the flue gas in absorption tower 100 is big
3 meters of each second is caused, is in bending harden structure since nethike embrane splashes when flue gas is by the multilayer splashing web plate 210 that is arranged in tower,
At this time the area of splashing nethike embrane than the cross section on absorption tower 100 area bigger, therefore flue gas pass through splashing web plate 210 when
Speed at 2 meters or so, meanwhile, when flue gas from bottom to top can touch when by splashing web plate 210 with absorbing liquid from top to bottom
It hits, flow back, when absorption drop from top to bottom is dropped in splashing web plate 210, absorbing liquid droplet can be formed on splashing web plate 210
Liquid film and droplet are broken, when harmful material in smoke is by splashing web plate 210, are intercepted by impact interception, online liquid film, droplet
The broken processes such as interception of splashing, improve the purification efficiency to harmful material in smoke, and reduction uses power, arrived energy-saving and emission-reduction
Purpose.
