Description

Sound wave ashing deduster
 
Technical field
The present invention relates to a kind of deduster, particularly a kind of deduster that utilizes sound wave ashing.
Background technology
Along with the raising of industrial development and people's environmental protection consciousness, add that the various haze phenomenons of current appearance and National Environmental standard are to dust concentration emission request, various dedusting technologies are developed, and various dedusters also just arise at the historic moment.
So far, what all kinds of dedusters utilizations were maximum is electrostatic precipitator and cloth bag (filter cylinder) deduster, no matter be electrostatic precipitator or sack cleaner, all has a general problem, be exactly the more difficult problem of deashing.Electric precipitation deashing is by mechanical vibrator pole plate of dust remover deashing, and long-time mechanical vibrator will certainly cause the damage of pole plate or polar curve and mechanical shaking device, needs timing to safeguard rapping apparatus and pole plate; And for sack cleaner, although be to carry out deashing by pulse valve blowing compressed air, support because filter bag of dust collector must have skeleton, in the time of winding-up compressed air, easily make cloth bag and bag cage rub, thereby reduce the service life of filter bag; No matter hence one can see that is electric precipitation or the current ash-clearing technology of bag dedusting, is all easy to increase the operating cost of deduster.
Make a general survey of the poor problem of operational effect that bag-type dust removing system occurs, the overwhelming majority causes resistance rising relevant with ash-removal effect is bad, therefore " deashing " is the deciding factor that is related to bag-type dust removing system success or failure.The quality of ash-removal effect is being related to the various indexs such as the economical operation benefit of resistance, efficiency, service life and the deduster of deduster.
The ash-clearing technology that existing Environmental-protecting dust-removing equipment adopts at present still rests on traditional mechanical vibrator or pulse jetting deashing, when dust accumulates dust on pole plate or on filtrate when more, dust cannot be removed thoroughly, causes resistance to rise, cause operating cost to raise, efficiency of dust collection is low.
Summary of the invention
The embodiment of the present invention provides a kind of sound wave ashing deduster, for from dusty gas by particulate separation out and trapped, reclaim.
A kind of sound wave ashing deduster, comprising:
For supporting and the casing of protective effect; Be arranged on air inlet and air outlet on casing, for passing into dusty gas and discharging clean gas; Be arranged on the ash bucket of casing below, the dust trapping for receiving deduster; Connect the negative-pressure air fan of air outlet, for keeping subnormal ambient in casing; Also comprise the sonic generator being arranged on casing, for the dust of clean box body both inner pad, polar curve or filter bag surface deposition.Described sonic generator is, by the conversion of gas sound, compressed-air actuated power conversion is become to acoustic energy, be radiated deashing space with certain frequency and sound level, due to the comprehensive propagation of sound wave, periodically alternation acoustic pressure acts on black dirt layer dust is departed from, and reaches deashing effect.
For the further improvement of technique scheme, described sonic generator is with signal generator, the humorous vibration cylinder of public address, acoustical generator and gas circuit centralized control system, and signal generator connects the humorous vibration cylinder of public address, and then is connected to acoustical generator; Signal generator sends frequency signal, and the humorous vibration cylinder of public address amplifies signal, and then makes acoustical generator send required sound wave; Gas circuit centralized control system is for controlling the work of sonic generator.
For the further improvement of technique scheme, the frequency setting of described sonic generator and the size of casing need to meet the following conditions: the sound wave that sonic generator sends can form at least two antinodes in the dirt pocket of casing.If antinode quantity is few, also just indicating that dust forms the number of times minimizing of maximum displacement campaign in sound field, can make collision frequency minimizing mutually in its motion process, so so its efficiency of dust collection can decline to some extent.If so consider dirt pocket physical dimension factor, while using dust collection by sound wave, meeting on the basis of enough antinodes and node quantity, also should select as far as possible low-frequency sound wave.
If described sound wave ashing deduster sack cleaner, sonic generator is arranged on the sidewall of casing.If described sound wave ashing deduster electric cleaner, be advisable in the top that sonic generator is arranged on casing.
For the further improvement of technique scheme, described sound wave ashing deduster also comprises the bypath system that connects air inlet and air outlet, for the too high or too low gas of exhaust temperature, and protection deduster intraware.In described bypath system, be provided with bypass valve, in the time that dusty gas is too high or too low for temperature, open bypass valve.
For the further improvement of technique scheme, described sound wave ashing deduster also comprises electric-control system, can automatically control the deashing of deduster and unload ash, ensures that deduster is in increasingly automated state.The various piece of deduster can be carried out automatically as requested or manually be controlled, and according to demand, interlock also can be set.
For the further improvement of technique scheme, described sound wave ashing deduster also comprises thermostatic control system.
As can be seen from the above technical solutions, the present invention has the following advantages:
1, sound wave ashing deduster ash-removal effect is good, and sound wave ashing is flexible deashing, to equipment not damaged; Sound wave can be radiated any one corner in deashing space, and deashing is more thorough; Sound wave ashing is noncontact deashing, can not produce influence of fluctuations to system operation; When deashing, without the intervention of moisture, moisture, while avoiding condensate moisture, corrode.
2, sound wave ashing deduster is simple in structure, and dust remover is easy for installation, can effectively remove the dust gathering on the dust of electric precipitation top crown or filter bag.
3, sound wave ashing deduster has improved the efficiency of dust collection of deduster greatly, without artificial deashing, saves human and material resources, reduces maintenance cost.
