Description
Technical field
The utility model belongs to electronic applications, refers in particular to a kind of dust concentration capacitive transducer apparatus for automatic change.
Background technology
Recently medical research shows that the generation of lung cancer is in rising trend, and particularly non-smoker's lung cancer incidence is in rising trend too.The appearance of existing this situation of bibliographical information is in close relations with PM2.5.PM2.5 refers to the particle that aerodynamic diameter is less than 2.5 microns, and it can adsorb various noxious materials and directly enter human body lower respiratory tract.Generally acknowledge now that PM2.5 is one of pollutant.
The fire coal that Thermal Power Enterprises, heating enterprise are used is one of important sources of PM2.5, thereby the improvement of these enterprise's emissions is the important means that suppresses PM2.5.In numerous improvement methods, electrostatic precipitation is a kind of comparatively desirable method.Electrostatic precipitation is mainly by charging particle, is then adsorbed and removes.
The research of electrostatic precipitation is extremely important for dust concentration in effective control air, but the evaluation of electrostatic precipitation effect is very difficult.Reason is that the smoke content before and after electrostatic precipitation is very little, measures very difficult.Traditional employing weight method, need to measure soot dust granule weight, thereby error was larger in the past.Capacitive transducer method with cheap, be conveniently widely used.Its principle is: according to electric capacity computing formula C=ε a/d, when in the constant situation of two pole plate relative area a, spacing d, dielectric coefficient ε changes with the size of fume amount, and dielectric signal electric capacity C just changes.Therefore, capacitance signal can be used as and detects ore-smelting electric furnace dust concentration index.When the fume amount of circulation increases, it is large that dielectric dielectric coefficient becomes, and it is large that electric capacity C just becomes; When circulation fume amount while reducing, dielectric dielectric coefficient diminishes, electric capacity c just diminishes.So just can measure dust concentration.Traditional capacitance measuring instrument capacitance electrode in measuring process is inevitably understood by contamination by dust, thereby affects measurement result.For fear of due to capacitance electrode, directly with flue dust contact, the generation of contaminated this phenomenon the utility model proposes a kind of dust concentration capacitive transducer apparatus for automatic change.
Summary of the invention
In order to overcome existing electric capacity concentration sensor, directly contact flue dust, thus contaminated deficiency, the utility model provides a kind of dust concentration capacitive transducer apparatus for automatic change, and this device can avoid sensor contaminated.
The utility model solves the technical scheme that its technical matters adopts: the utility model device is by motor, motor shaft, electric machine support, microswitch, flue, front sampling flue, lower dust board, the new pole plate of lower electric capacity, upper dust board, lower capacitor plate, upper capacitor plate, the new pole plate of upper electric capacity, walling of flue, upper insulation layer, lower insulation layer, triode, single-chip microcomputer, relay, front sampling walling of flue, middle sampling flue, rear sampling flue composition, it is characterized in that: motor by motor shaft with rectangular upper insulation layer, rectangular lower insulation layer is connected, front sampling flue is connected with rear sampling flue by middle sampling flue, rectangular upper capacitor plate is connected by the new pole plate of the same electric capacity in upper insulation layer, lower capacitor plate is connected with the new pole plate of lower electric capacity by lower insulation layer, microswitch ditto samples walling of flue and is connected, rectangular microswitch is connected with single-chip microcomputer, and motor is connected with single-chip microcomputer by relay, triode, resistance.
Flue and front sampling flue, middle sampling flue, rear sampling flue are cylindric, and front sampling flue is identical with rear sampling flue diameter and be greater than middle sampling flue.The new pole plate of lower electric capacity, upper dust board, lower capacitor plate, upper capacitor plate, the new pole plate of upper electric capacity, upper insulation layer, lower insulation layer are rectangle.
When after dust concentration capacitive transducer work a period of time, its lower capacitor plate, upper capacitor plate all can accumulate many soot dust granule things, thereby have affected measurement result.Now, microswitch has also adhered to many soot dust granule things.Be subject to the effect microswitch closure of gravity, connect ground end.It is 0 that single-chip microcomputer monitors the connected port level of microswitch, sends instruction, by resistance, triode, relay, connects motor power, and driven by motor motor shaft rotates, and motor shaft drives its blade rotation.Its blade is upper capacitor plate, the new pole plate of upper electric capacity, upper insulation layer; Its lower blade is lower capacitor plate, the new pole plate of lower electric capacity, lower insulation layer.When turning over 180 while spending, completed the exchange of new and old capacitor plate.
Upper capacitor plate, the new pole plate of upper electric capacity, upper insulation layer are that the copper sheet of carving in the middle of going on same circuit board is made; Same upper capacitor plate, the new pole plate of lower electric capacity, lower insulation layer are also for the copper sheet of carving in the middle of going on same circuit board is made.Upper dust board and lower dust board are for blocking because flue dust leakage is caused in the gap of capacitor plate conversion.
The beneficial effects of the utility model are to avoid photoelectric sensor directly to contact flue dust.It is mainly used in high-pressure electrostatic precipitation field.
