Detailed description of the invention
The present invention is described further below in conjunction with the accompanying drawings.
As it is shown in figure 1, Wet type cyclone dust arrester of the present invention include being sequentially connected connect conditioning Tower 1, gas-liquid coupler 2, Wen Qiu In pipe 3 and cyclone separator 4;Described conditioning Tower 1 is provided with ash-laden gas entrance 11 and spray equipment 12, described spray equipment 12 include water inlet pipe 121, control valve 122 and some hydraulic spray nozzles 123;Described gas-liquid coupler 2 includes some sheathed fixing Guide shell 21 together and the multiple blades 22 being arranged between adjacent guide cylinder 21;Described Venturi tube 3 includes contraction section 31, throat 32 and diffuser 33;Described cyclone separator 4 include cyclone inlet 41, cyclone separator body 42, Ash cylinder 43, ash discharging hole 44, central row trachea 45, filter 46 and neat stress outlet 47;The contraction section of described Venturi tube 3 31 are connected with gas-liquid coupler 2, and the diffuser 33 of described Venturi tube 3 is connected with cyclone inlet 41.
Described some hydraulic spray nozzles 123 for be uniformly placed equidistant, the opening direction the most horizontally toward gas-liquid of described hydraulic spray nozzle 123 Bonder 2, i.e. consistent with air-flow inflow direction.
The blade 22 of described gas-liquid coupler 2 is the most radially uniform to be in tilted layout.
Described cyclone separator 4 is the reverse-flow cylinder cone separator with tangential inlet.
Described cyclone separator body 42 includes that shell portion and conical section, described conical section are positioned under described shell portion Side, and be combined as a whole.
The height of described cyclone separator body 42 is 4~4.5:1 with the ratio of the diameter of shell portion, is conducive to improving dedusting effect Rate.
The lower section of described conical section is ash cylinder 43, and the end of described ash cylinder 43 is ash discharging hole 44.
The lower edge of described central row trachea 45 is lower along concordant with described cyclone inlet 41.
