The utility model is characterized in that a dust concentration sensing transmitter is arranged behind the airflow distribution plate on the outlet side of the electo-precipitator, the output end of the dust concentration sensing transmitter is connected with a computer, and the signal-output end of the computer is connected with a frequency modulation loop of the anode rapping intelligent frequency modulating and speed adjusting machine of the electo-precipitator.
Description
[technical field]
The utility model relates to a kind of electric cleaner anode rapping intelligence frequency modulation device, especially relates to a kind of electric cleaner anode rapping intelligence frequency modulation device based on electric cleaner outlet side dust concentration intellectual monitoring technology.
[background technology]
The rapping of electric cleaner anode is the same with the corona discharge electrode rapping, be electric cleaner in running, remove laying dust, prevent the key measure of corona blocking.Because the effective area of positive plate assembly is far longer than corona discharge electrode, so the result of use of anode rapping apparatus is to weigh an important technology parameter of electric cleaner running status, it is related to electric cleaner Technical conditions of equipment serviceability rate, can starts important technology economic indicators such as rate, utilization rate and efficient.
The early 1990s in last century, with the computer technology is core, with the digitizing technique is the intelligent monitoring diagnostic techniques input commercial Application of feature, along with popularizing of frequency conversion and speed regulation of AC motor technology, in environmental protection cleaner technical fields such as electric cleaners, the anode rapping state monitoring apparatus based on equipment condition monitoring and fault diagnosis technology occurred, anode rapping state monitoring apparatus has played crucial effects to the every technical-economic index that improves the electric cleaner equipment running status undoubtedly.
In recent years, because in fundamental state policy has been listed environmental protection by China, State Environmental Protection Administration and environmental administration at different levels are more and more tighter to the control of enterprise's fume emission index, and people urgently wish to obtain a kind of effective ways that can further improve the electric cleaner dust-collecting efficiency.Through many experts and scholars and engineers and technicians' exploration, find that anode rapping frequency, particularly last utmost point anode rapping frequency are to influence the key factor that the electric cleaner dust-collecting efficiency improves.The rapping frequency is not enough, forms corona blocking easily, the rapping overfrequency, and the dust secondary fly-up because of rapping causes can reduce dust-collecting efficiency.Because the electric cleaner complex structure, changes in process parameters is big, because of technological reason inlet flue gas amount and dust concentration frequent fluctuation, determines a very rational rapping frequency by calculating, and is the thing of a very complicated and almost impossible realization.
[utility model content]
In order to overcome in the prior art, because of anode rapping frequency, particularly last utmost point anode rapping fixed-frequency constant, under the bigger situation of technological parameter fluctuations such as exhaust gas volumn and dust concentration, occur rapping overfrequency or rapping deficiency shortcoming, the utility model provide a kind of on the basis of anode rapping status monitoring, realize the electric cleaner anode rapping intelligence frequency modulation device of anode rapping intelligence frequency modulation function.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of electric cleaner anode rapping intelligence frequency modulation device, comprise electric cleaner, after described electric cleaner outlet side airflow-distribution board, be provided with the dust concentration sensing transducer, the output of this dust concentration sensing transducer links to each other with computer, and the output signal end of computer links by the frequency modulation loop of execution unit and electric cleaner anode rapping frequency control motor.
Described dust concentration sensing transducer is installed in the reducer pipe of electric cleaner outlet side and the binding site of diameter tube by flange.
The beneficial effects of the utility model are: utilize this non-electricity measure element of dust concentration sensing transducer, electric cleaner outlet side dust concentration situation of change is converted into data signal, after machine is handled as calculated, act on the frequency modulation loop of anode rapping frequency control motor by execution unit, for the rapping of electric cleaner anode provides a kind of effective intelligent frequency modulation device.
