Powder machine and blender stop adding powder.
Dust removing units case 210 is additionally provided with deflector, and deflector and air inlet are respectively positioned between ash bucket and dust-removal cloth-bag, water conservancy diversion
Plate is opposite with air inlet position.Stop after adding powder, opens the valve of air inlet, the mixed dust that will be mixed to form in exhaust piping
Air-flow introduces dust removing units case 210 in the horizontal direction, and deflector is arranged along the vertical direction, and mixed dust air-flow encounters deflector
Afterwards, the macromolecular exhaust gas particle in air-flow is directly settled down in ash bucket by hitting deflector, the small molecule exhaust gas in air-flow
Grain rises after hitting deflector with air-flow along the vertical direction, flows through the outer surface of dust-removal cloth-bag, is attached removing.Remaining cleaning
Air enters inside dust-removal cloth-bag and by being discharged with the exhaust pipe being connected to inside dust-removal cloth-bag.By dust removing units case 210
The top of air inlet is arranged in gas outlet, can guarantee that adhesive dust and dry powder is allowed further to mix, and promotes effect.
Cloth bag purge system includes the wind pressure sensor and purger for monitoring the attached powder amount of dust-removal cloth-bag, intelligent control
Equipment controls the outer surface that purger clears up dust-removal cloth-bag by the feedback signal of wind pressure sensor.Dust removal and filtration operating mode
Under, when wind pressure sensor detects the approach of the pressure difference in the case of Cell 210 and outside case with zero, by signal feedback to intelligent control
Control equipment, and purger is opened, the outer surface of dust-removal cloth-bag is purged.Since the adhesion molecules in exhaust gas are by dry powder
Package, and cloth bag surface is equipped with dry powder layer, therefore purging becomes easy.When case inside and outside differential pressure restore when, stop purging, close into
The valve of port continues the step of phase dedusting cloth bag surface adds powder.In the particular embodiment, purger is with pulse valve
Compressed air bag, can to dust-removal cloth-bag surface carry out pulse jetting deashing.
Pre- dusting device 1 includes dry powder feed bin 110, pulverized coal feed pipe, powder feed system and blower 120, the both ends of pulverized coal feed pipe
It is connected to respectively with exhaust piping and blower 120, powder feed system is sent into dry powder, powder feed system and wind in the middle section of pulverized coal feed pipe
Machine 120 is electrically connected with intelligent control device.Blower 120 selects high pressure cyclone cluster, can accelerate to be blown into containing adhesiveness by dry mash
The conveyance conduit of dust exhaust gas reaches mixed uniformly effect.
Powder feed system includes weighing sensor 140, servo motor 150 and conveying lever 160, and servo motor 150 is for controlling
The conveying speed of conveying lever 160, powder outlet quantity of the weighing sensor 140 for dry powder feed bin 110 of weighing, servo motor 150 and title
Sensor 140 is retransmitted to connect with intelligent control device.Powder is conveyed using twin-screw, guarantees the uniformity of feeding, is equipped with simultaneously
Servo motor can adjust according to adhesive dust concentration in exhaust gas and throw powder amount.Weighing sensor and servo motor with intelligent control
Control equipment electrical connection, can detecte pre- powder spraying apparatus high charge level and low material position, while to the weight change for entirely adding process
Play detection；The uniform of process that entirely feed intake, abnormal conditions alarm can be reached by controlling servo motor revolving speed.
As shown in figure 3, the waste gas processing method of the exhaust treatment system, mainly comprise the steps that determine be suitable for
The attached powder amount of most suitable unit area for handling the most suitable amount of dusting and dust-removal cloth-bag of the pre- dusting device of exhaust gas, is input to intelligence
Control equipment；Drainage blower is opened by intelligent control device, and opens the solenoid valve of each gas outlet one by one and closes every
The solenoid valve of a air inlet and each dust-removal cloth-bag add powder system, so that multiple dust removing units casees sequentially enter dust-removal cloth-bag appearance
Face adds powder operating mode, reaches the attached powder amount of most suitable unit area；The solenoid valve and pre- dusting device of each air inlet are opened one by one,
And successively close dust-removal cloth-bag and add powder system, so that multiple dust removing units casees sequentially enter dust-removal cloth-bag dust removal by filtration Working mould
Formula, until the wind pressure sensor of corresponding dust-removal cloth-bag purging system sends open signal to intelligent control device；Pass through intelligence
Control equipment successively opens the purger of dust-removal cloth-bag purging system, so that multiple dust removing units casees sequentially enter dust-removal cloth-bag
Removing surface operating mode, until the wind pressure sensor of corresponding dust-removal cloth-bag purging system successively sends stop signal to intelligence
Control equipment；Multiple dust removing units casees are controlled by intelligent control device and are repeated in step b-d, until will be at exhaust gas to be processed
Reason is clean and is discharged.
