The rapping and deashing device disclosed by the utility model has the advantages of good deashing effect, long service life and convenience in maintenance, and can be used for realizing overhaul without shutdown and improving the use efficiency of equipment.
Description
Technical field
The utility model relates to high-voltage electrostatic dust separator, especially a kind of ash removal equipment for flapping that adopts the high-voltage electrostatic dust separator of grating type pole plate.
Background technology
High-voltage electrostatic dust separator is to receive the device of catching dust in the flue gas with the electrostatic depuration method, relies on discharge electrode and receiving electrode to receive and catches dust in the flue gas, and the dust that deposits when the two poles of the earth reaches when a certain amount of; Pass through vibration body; Beat the two poles of the earth, the dust that sticks on the two poles of the earth is shaken off, fall into the bottom ash bucket outside ash exhauster discharge machine; Reach dedusting, the purpose of flue.
The existing positive plate that is used for high-voltage electrostatic dust separator has two kinds usually, and a kind of is board-like pole plate, and another kind is the grating type pole plate; The decay of rapping power was big when board-like pole plate adopted top rapping; Ash-removal effect is poor, and the grating type pole plate is when adopting top rapping, and the grating type pole plate damages easily; Therefore the normal vibration dust-cleaning mode that adopts of these two kinds of pole plates is a side rapping mode; But it is big that the structure of side rapping takies the high-voltage electrostatic dust separator body plenum, and shaking cycle and rapping power are non-adjustable, each component wear is big, and pole plate is shorter service life.
The utility model content
The technical problem that the utility model will solve provides a kind of ash removal equipment for flapping that adopts the high-voltage electrostatic dust separator of grating type pole plate, and ash-removal effect is good, and long service life is easy to maintenance, can realize on-line maintenance, improves the equipment service efficiency.
For achieving the above object; The technical scheme of the utility model is: a kind of ash removal equipment for flapping that adopts the high-voltage electrostatic dust separator of grating type pole plate; Comprise a plurality of grating type pole plates, the vibration body that includes a plurality of electromagnetic rapping hammers that is arranged in the electric field, the ash bucket that is arranged at a plurality of grating type pole plates bottom; Weld with a rapping anvil beam mutually at the top of two or three adjacent grating type pole plates, and the top of each rapping anvil beam is provided with the electromagnetic rapping hammer, and described vibration body is arranged at outside the electric field.
Preferred said each grating type pole plate and the position that rapping anvil beam welds mutually are in the mid portion at grating type pole plate top, make the transmission of rapping power on the grating type pole plate more even.
Further improve; Described vibration body is provided with automatically controlled part the rapping power of each electromagnetic rapping hammer is controlled separately; Make rapping can divide little rapping zone; Take different rapping dynamics, shaking cycle to each electric field, dust stratification characteristics that each is regional, further improve the vibration dust-cleaning effect.
The utility model is owing to weld with a rapping anvil beam at the top of two or three adjacent grating type pole plates mutually, and the top of each rapping anvil beam is provided with the electromagnetic rapping hammer, and the rapping power of beater passes to two or three grating type pole plates simultaneously through rapping anvil beam; Because grating type electrode plate structure characteristics; The transmission of this rapping power is even, and decay is few, can shake the dust stratification on the grating type pole plate preferably and fall in the ash bucket; Satisfy the dust removing effects requirement of high-voltage electrostatic dust separator; In addition, interconnect two or three grating type pole plates, improve bulk strength through rapping anvil beam; Prevent that effectively the grating type pole plate from damaging, and improves the service life of whole high-voltage electrostatic dust separator in rapping.
On the other hand, described vibration body is arranged at outside the electric field, does not take electric field space in addition; Make the high-voltage electrostatic dust separator body plenum be utilized, make vibration body easy to maintenance simultaneously, can realize on-line maintenance; The downtime of minimizing equipment, improve the equipment service efficiency.
Description of drawings
Fig. 1 is the utility model front view.
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the utility model is done further explain.
Fig. 1, shown in Figure 2; A kind of ash removal equipment for flapping that adopts the high-voltage electrostatic dust separator of grating type pole plate; Comprise a plurality of grating type pole plates 1, the vibration body that includes a plurality of electromagnetic rapping hammers 2 that is arranged in the electric field 10, the ash bucket 3 that is arranged at a plurality of grating type pole plates 1 bottom; Weld with a rapping anvil beam 4 mutually at top at two adjacent grating type pole plates 1; Also available adjacent three grating type pole plates 1 weld with a rapping anvil beam 4 mutually, and the position that is welded to each other is in the mid portion at grating type pole plate 1 top;
An electromagnetic rapping hammer 2 is set on the top of each rapping anvil beam 4 then, and the said vibration body that includes a plurality of electromagnetic rapping hammers 2 is arranged at outside the electric field 10.
Described vibration body is provided with automatically controlled part the rapping power of each electromagnetic rapping hammer 2 is controlled separately.
During the utility model vibration dust-cleaning; The electromagnet portion energising back of electromagnetic rapping hammer 2 promotes its inner beater 21 through electromagnetic force; The outage of the electromagnet portion of electromagnetic rapping hammer 2 loses electromagnetic force then, and beater 21 knocks on rapping anvil beam 4 freely falling under the gravity effect, and rapping power passes to grating type pole plate 1 through rapping anvil beam 4; Make grating type pole plate 1 produce shake, thereby make the dust on the grating type pole plate 1 break away from polar board surface and fall into ash bucket 3.
Below only be preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
