Further, described ash discharging system comprises unloading valve and conveying worm, and described unloading valve is located at cinder-discharging port place, and described conveying worm is communicated with cinder-discharging port.
Further, described dust-removing control system comprises dust-removing control device, resistive force sensor and electromagnetic impulse valve, described resistive force sensor is located in each case district, described electromagnetic impulse valve is located at the top in case district, be communicated with air accumulator with by compressed air road system, described dust-removing control device is electrically connected with resistive force sensor and electromagnetic impulse valve respectively.
Further, described dust-removing control system comprises dust-removing control device, timer and electromagnetic impulse valve, is communicated with air accumulator by compressed air road system, and described dust-removing control device is electrically connected with timer and electromagnetic impulse valve respectively.
Further, described ash bucket is provided with bunker wall vibration device.
Further, be provided with anti-explosion safety locking device in described casing, when high pressure appears in casing, releasing pressure automatically, pressure normally recovers normal operation afterwards.
Compared with prior art, the utility model compact conformation, long service life, efficiency is high; During chamber-dividing counter-blowing, kinetic energy intensity is large, and energy impulse winding-up is filtered and carried out with deashing simultaneously, has divided several case district, be provided with lift valve above each case district in casing; Deashing intensity is large, speed is fast, cycle period is short, and air inlet is located on lower box, and gas outlet is located on upper box; Deashing ability and to unload grey ability strong, is respectively equipped with dust-removing control system and ash discharging system.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment;
Fig. 2 is the side view shown in Fig. 1;
Fig. 3 is top view shown in Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
With reference to accompanying drawing 1, Fig. 2 and Fig. 3, the present embodiment comprises upper box 1, ash bucket 2, compressed air road system 3, dust-removing control system and ash discharging system, the bottom of described upper box 1 is communicated with the upper end of ash bucket 2, described upper box 1 is provided with gas outlet 5, the top of described ash bucket 2 is provided with air inlet 4, described upper box 1 is divided into several case district 10, filter bag is provided with in described case district 10, the top outlet conduit in each case district is equipped with cylinder and drives lift valve 6, described cylinder drives lift valve 6 to be all communicated with air accumulator 7 by compressed air road system 3, the bottom of described ash bucket 2 is provided with cinder-discharging port 8, described cinder-discharging port 8 is connected with ash discharging system, described dust-removing control system is electrically connected with lift valve 6.
Ash discharging system comprises unloading valve 9 and conveying worm (not shown), and unloading valve 9 is located at cinder-discharging port 8 place, and conveying worm (not shown) is communicated with cinder-discharging port 8.
Dust-removing control system comprises dust-removing control device, resistive force sensor and electromagnetic impulse valve, described resistive force sensor is located in each case district, described electromagnetic impulse valve is located at the top in case district, be communicated with air accumulator 7 by compressed air road system 3, described dust-removing control device is electrically connected with resistive force sensor and electromagnetic impulse valve respectively.
Ash bucket 2 is provided with bunker wall vibration device (not shown), avoids that coal dust humidity is excessive occurs that ash bucket 2 condenses, blocking unloading valve 9.
Be provided with anti-explosion safety locking device (not shown) in casing, when high pressure appears in casing, releasing pressure automatically, pressure normally recovers normal operation afterwards.
Ash bucket 2 cone wallboard inclination angle >=70 °, prevent because dust stratification in dust-precipitator causes spontaneous combustion to explode.
During work, ash-laden gas is after the air inlet 4 on ash bucket 2 top enters ash bucket 2, the grit that part is larger directly falls into ash bucket because collision, natural subsidence etc. act on, other grits rise with air-flow and enter each pocket type, after dust in ash bucket 2, grit is delayed at outside filter bag, and purified gas enters upper box by filter bag inside, air is entered again, dust in ash bucket 2 timing or drawn off by unloading valve 9 and spiral conveying mechanism continuously by lift valve 6, air outlet 5.
Along with constantly carrying out of filter process, outside filter bag, appended long-pending dust constantly increases, thus cause the resistance of dust-precipitator itself also to raise gradually, when resistance reaches preset value, dust-removing control device sends signal, first the lift valve 6 of a bag room is made to close to cut off the filtered airflow of this room, then electromagnetic impulse valve is opened, in case, compressed air is sprayed into the extremely short time, compressed air expands at a high speed in case, filter bag is made to produce high-frequency fluctuation distortion, add the effect of inverse air-flow, appended dirt cake distortion outside filter bag is come off, in the sedimentation time taking into full account dust, after ensureing that the dust come off effectively can fall into ash bucket, lift valve 6 is opened, during deashing, each room is carried out in order respectively, do not interfere with each other, realize carrying out continuously for a long time.
Embodiment 2
The difference of the present embodiment and embodiment 1 is only, dust-removing control system comprises dust-removing control device, timer and electromagnetic impulse valve, is communicated with air accumulator 7 by compressed air road system 3, and described dust-removing control device is electrically connected with timer and electromagnetic impulse valve respectively.
All the other are substantially the same manner as Example 1.
