Abstract

The utility model discloses an automatic monitoring device of static dedusting equipment and belongs to the field of electronics, and the automatic monitoring device is mainly used for solving the technical problem of overcoming the defect that people need to crawl into a flue during the discharging monitoring of the existing static dedusting polar plate. The automatic monitoring device comprises a holder, a bracket, a camera, a singlechip, a dustproof hood, a dustproof hood motor and a singlechip. When dedusting electrodes are subjected to electricity discharge, the current connected with the negative electrode is increased because of the electricity discharge between the dedusting electrodes, the voltage at two ends of sampling resistors which are serially connected with the negative electrode is increased, and the voltage is conducted to the singlechips; when the singlechips receive a discharging current signal of the dedusting electrodes, the discharging current signal is compared with a limit value stored in the singlechips, when the value is larger than the limit value, an instruction is transmitted to open the dustproof hood, and the camera starts taking pictures; in order to take the discharging pictures in time, the camera is always in a working state; and because of the large fume in the flue, the dustproof hood is usually in a closed state. The automatic monitoring device is mainly applied to the static dedusting field.

Description

A kind of electrostatic dust collection equipment automatic monitoring device

Technical field

The utility model belongs to electronic applications, refers in particular to a kind of electrostatic dust collection equipment automatic monitoring device.

Background technology

Utilize coal fired power generation and heating also to occupy sizable proportion in China, guaranteeing to play irreplaceable effect aspect industrial and agricultural production and people's lives.Inevitably can produce a large amount of flue dust in power generation process.Dedusting method can be divided into mechanical type, wet type, electrostatic precipitation, bag-type dust.Wherein electrostatic precipitation is that efficiency is higher, a kind of mode that treating capacity is larger.When in flue gas, the dust grit is by high-voltage electrostatic field, with interelectrode negative ions and electronics bump charged (or charged in the ion diffusion motion), grit anisotropy electrode movement long-pending being attached on different in nature electrode under the effect of electric field force with upper electronics and ion, by modes such as rappings, make the dust on electrode fall into the collection ash bucket, make to be purified by the flue gas of electric cleaner.The battery lead plate of electrostatic precipitation is arranged in flue.Dust accumulation or other deposit due to too much, may cause discharging between electrode, now can, with the sound, have flash of light and circuital current to increase simultaneously.Between electrode, electric discharge may damage the even excessive electric current of electrodes for removing dust plate and may damage power supply.This kind of situation occurs to be needed the people to enter flue to check in the past.In flue, condition is very arduous and dangerous.In order to change this situation, the utility model proposes the generation that a kind of electrostatic dust collection equipment automatic monitoring device can be avoided above-mentioned event effectively.

The utility model is mainly used in the electrostatic precipitation field.

Summary of the invention

Rely in order to overcome existing electrostatic precipitation pole plate electric discharge monitoring the deficiency that manually climbs into flue, the utility model provides a kind of electrostatic dust collection equipment automatic monitoring device, and this device can be monitored electrostatic dust collection equipment electrode discharge situation automatically.

The utility model solves the technical scheme that its technical problem adopts: the utility model device is comprised of The Cloud Terrace and support, video camera, single-chip microcomputer, dust cover, dust cover motor, single-chip microcomputer, it is characterized in that video camera is arranged on walling of flue by The Cloud Terrace and support.

Video camera is arranged among flue, and the impact for fear of flue dust on it, install dust cover by it.The unlatching of dust cover and close by dust-proof motor power is provided, by Single-chip Controlling, its shooting angle can be passed through cradle head control.

Produce electric discharge when between electrodes for removing dust, because causing the electric current that is connected in negative pole, the electric discharge between electrodes for removing dust increases, the both end voltage that is serially connected in the sample resistance of negative pole increases, this voltage is sent to adc circuit through insurance resistance, after the modulus circuit integrated package, deliver to single-chip microcomputer, insurance resistance damages adc circuit and single-chip microcomputer in order to prevent excessive electric current.

Single-chip microcomputer, after receiving the discharge current signal of electrodes for removing dust, compares with the limiting value of its storage, when its value is greater than limiting value, sends instruction, by resistance, triode, relay, starts the dust cover motor, opens dust cover, and video camera starts shooting.For the image of picked-up electric discharge in time, video camera is always in running order.Because flue dust in flue is large, for this reason at ordinary times its dust cover in closed condition.

The beneficial effects of the utility model are to realize electrostatic precipitation pole plate electric discharge monitoring automatically.It is mainly used in the electrostatic precipitation field.
