For the particle removed in collecting dust-removing device.
Can storehouse pump the particle in dust arrester is collected, it is ensured that particulate matter in cyclone dust collector 180
Content is remained in a relatively low scope, so that cyclone dust collector 180 uninterruptedly can continuously work,
Improve production efficiency.
In the present embodiment, in addition to pneumatic cold blast sliding valve 160 and valve control device, pneumatic cold blast sliding valve 160 are arranged on
The inside of one pipeline 130 or cleaning position 120, valve control device are used to control being turned on and off for pneumatic cold blast sliding valve 160.
In the case that flue gas air near dust removal piece 123 is too high, pneumatic cold blast sliding valve 160 can be opened, so as to
The air for making temperature relatively low is entered in cleaning position 120, can be with so as to reduce the temperature of the flue gas near dust removal piece 123
One is carried out to dust removal piece 123 to be effectively protected.
And valve control device is controlled to pneumatic cold blast sliding valve 160 as prior art, will not be repeated here.
In the present embodiment, in addition to temperature sensing device, temperature sensing device are positioned close to the position of dust removal piece 123
Put, temperature sensing device and valve control device electrical connection, temperature sensing device and spray equipment 150 electrically connect.
Temperature sensing device is used for the temperature for sensing the flue gas near dust removal piece 123, the flue gas temperature near dust removal piece 123
When spending high, signal is passed to valve control device by temperature sensing device, and valve control device controls pneumatic cold blast sliding valve
160 open, and the air so as to make temperature relatively low enters the inside of cleaning position 120, near to dust removal piece 123
Flue gas cooled, prevent the too high flue gas of temperature to caused by dust removal piece 123 damage.
Spray equipment 150 is internally provided with spray control device, and spray control device can opening to spray equipment 150
Open or close and be controlled, specific control mode is prior art, be will not be repeated here.
In the present embodiment, in addition to second pipe 140, one end of second pipe 140 connect with cleaning position 120, and second
The other end of pipeline 140 is connected with air-introduced machine 110, and air-introduced machine 110 is used to cause cleaning position 120 to keep negative pressure.
Cleaning position 120 that air-introduced machine 110 is keeps negative pressure, so that the flue gas by purification is from second pipe
Flowed out in 140, prevent the smoke backflow by purification.
In the present embodiment, in addition to explosion-proof valve 170, explosion-proof valve 170 and cleaning position 120 connect, and explosion-proof valve 170 is used for will
High pressure release in cleaning position 120.
When work, it may occur that the problem of imperfect combustion occurs in kiln and causes detonation, explosion-proof valve 170
High pressure caused by detonation can slowly be discharged, so as to prevent kiln and whole gas cleaning dust arrester 100 from sending out
The situation of raw blast.
The operation principle for the gas cleaning dust arrester 100 that the present embodiment provides is when work, can to pass through spray
Shower device 150 sprays reactant to dust removal piece 123, and reactant can prevent the hole 1231 in dust removal piece 123 from blocking, and react
Thing can be talcum powder either activated carbon, and talcum powder can make it that dust granules are smooth, and activated carbon has adsorption capacity, from
And it can prevent that the particle in flue gas from occurring dew condensation phenomenon, prevents the hole 1231 in dust removal piece 123 from blocking.
