Stop valve and regulation valve, the outlet of each branch road water knockout drum connects one end of a plurality of connection flexible pipe, a plurality of connection flexible pipe another
Silk is connected by one end respectively with multiple, multiple to silk connection corresponding with multiple shower nozzles respectively, and silk and shower nozzle are arranged on flange
On.
Above-mentioned regulation Venturi tube flue gas flow and the water injector of dedusting, described flange is square flange, multiple to silk peace
Being contained in the side of flange, multiple shower nozzles are arranged on the opposite side of flange, each are connected silk and a shower nozzle, multiple to silk and
Shower nozzle is order arrangement on flange, and their spacing is equal, and silk with multiple is by the connection flexible pipe of multiple branch road water knockout drums respectively
Interval connects.
Above-mentioned regulation Venturi tube flue gas flow and the water injector of dedusting, the plurality of flange is fixed on by bolt is staggered
Venturi tube both sides.
The beneficial effects of the utility model are:
This utility model utilizes water column regulation Wen's inner tube smoke stream that the square flange of interlaced arrangement and shower nozzle spray out
Dynamic gap, can be by solidifying after being combined with the globule to flue gas and the water droplet high velocity impact in Pen Rushi pipe, the dust granules in flue gas
Gather and be discharged, reach to regulate flue gas flow and dedusting purpose.This utility model simple in construction, easy to use, dust removing effects is good
Good, have only to time properly functioning provide production water, the production water after using flow to mudpan through dirt discharge groove, after precipitation
Production water, through associating pumping plant recycling, has the advantages such as reliability is high, split controls, easy to maintenance, is regulation Venturi tube
Flue gas flow and effective equipment of dedusting, have the value promoted the use of.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, label is as follows: inlet channel 1, total water knockout drum 2, stop valve 3, regulation valve 4, branch road inlet channel 5, branch road divide
Hydrophone 6, connect flexible pipe 7, to silk 8, flange 9, shower nozzle 10.
Detailed description of the invention
This utility model is divided by inlet channel 1, total water knockout drum 2, stop valve 3, regulation valve 4, branch road inlet channel 5, branch road
Hydrophone 6, connect flexible pipe 7, silk 8, flange 9, shower nozzle 10 are formed.
Showing in figure, inlet channel 1 is welded direct on total water knockout drum 2, and multiple branch road water knockout drums 6 are entered by a plurality of branch road
Waterpipe 5 is connected on total water knockout drum 2, is separately installed with stop valve 3 and regulation valve 4 on every branch road inlet channel 5, each
The outlet of branch road water knockout drum 6 connects one end of a plurality of connection flexible pipe 7 respectively, and the other end of a plurality of connection flexible pipe 7 is respectively with many
Individual silk 8 is connected, multiple connects silk 8 is corresponding with multiple shower nozzles 10 respectively, silk 8 and shower nozzle 10 are arranged on flange 9.
Showing in figure, flange 9 is square flange, multiple sides that silk 8 is arranged on flange 9, and multiple shower nozzles 10 are arranged on
