Description
Technical field
The utility model relates to the automatic testing and alarm device of a kind of fault, is specially adapted to electric cleaner dust removing system.
Background technology
Electric cleaner is the requisite environmental protection equipments such as thermal power plant, steel mill, chemical plant, cement plant, and its function removes the dust in industrial smoke, thus significantly reduce the fume amount entered in atmosphere.Electric cleaner is decreasing pollution, environmental protect, improves the important environmental protection equipment of air quality.
The operation principle of electric cleaner is the highfield utilizing high voltage direct current to produce, the gas molecule in industrial smoke is made to be ionized into a large amount of electronics and ion, move to the two poles of the earth under the effect of electric field force, the dust granules encountered in moving process in air-flow makes it charged, Charged moves to opposite polarity pole plate or polar curve with flow separation under electric field force effect, Charged is adsorbed on pole plate or polar curve by electrostatic force when arriving pole plate or polar curve, make dust fall into storage ash system and ash bucket by rapping apparatus, thus make gas cleaning.
Electric cleaner body critical piece comprises: smoke box system, corona discharge electrode system, dust collector pole system, trough plate system, storage ash system, housing, pipeline, housing insulation and ladder landing platform etc.
The function of storage ash system is that the dust fallen from electrode is concentrated, and delivers in other device through dust removing system and go.General ash bucket is quadrangular frustum pyramid shaped or prism-shaped, the ash discharge of quadrangular frustum pyramid shaped ash bucket many employings star rotary ash discharge valve sequence timing, the continuous ash discharge of prism-shaped ash bucket many employings scraper plate ash ejector.
The storage ash system accident of electric cleaner is more, the particularly ash bucket of timing ash discharge, and often because ash bucket dust stratification overfill causes corona discharge electrode ground connection, electric field is short-circuited, and has a strong impact on the normal production run of electric cleaner.Adopt the ash bucket of the continuous ash discharge of scraper plate ash ejector, if dust removing system fault and not by Timeliness coverage, now situation can be even more serious: except ash bucket dust stratification overfill, cause corona discharge electrode ground connection, electric field is short-circuited outside tripping operation, the drag chain of scraper plate ash ejector may be broken because of heavy overload, and now whole system can only be forced to parking maintenance.Specific practice is: open urgent ash removing opening, with the dust stratification in traditional artificial ash removal method discharge ash bucket.Because artificial urgent deashing needs to carry out under system shutdown state, and the length that expends time in, need a large amount of work personnel and haulage vehicle, thus have a strong impact on production.Again because artificial deashing is open type operation, reentrainment of dust certainly will be caused, the environment around severe contamination.In order to solve the problem, if can provide fault automatic testing and alarm device for electric cleaner dust removing system, be convenient to people's Timeliness coverage and handling failure, avoid fault spread and impact to produce, is the problem that this patent needs to solve.
Utility model content
The technical solution of the utility model is:
Adopt corresponding sensor to detect all relevant equipment and parts in electric precipitation dust removing system and whether have fault, once break down, alarm signal is sent at once to alarm unit, alarm unit is after receiving any fault-signal that checkout gear sends, automatically send sound and light alarm signal, be convenient to people's Timeliness coverage and handling failure.
Described system comprises automatic detection unit and alarm unit, described automatic detection unit comprise sensor one for detecting scraper plate ash ejector fault-signal, for detect scraper plate ash ejector drive motors fault-signal sensor two, for detect star-like rotary discharge valve fault-signal sensor three, for detect star-like rotary discharge valve drive motors fault-signal sensor four, for detecting the smooth or sensor five of plugging fault signal of downstream unit ash discharge and the sensor six for detecting ash bucket dust stratification height; Be connected by shielded cable between described alarm unit and each sensor of described automatic detection unit, after automatic detection unit detects that any fault occurs electric cleaner dust removing system, send corresponding alarm signal to alarm unit immediately, after alarm unit receives alarm signal, can automatically send sound and light alarm signal rapidly.Describedly velocity sensor is all adopted to detect it whether in normal operation for detecting the running devices such as scraper plate ash ejector, the drive motors of scraper plate ash ejector, star-like rotary discharge valve, star-like rotary discharge valve drive motors or parts, if equipment shuts down, then sensor sends corresponding alarm signal to alarm unit immediately; Downstream unit ash discharge is smooth or block the detection of employing temperature sensor, because once downstream unit ash discharge is not smooth or blocking, the temperature of the ash discharging pipe below star-like rotary discharge valve will decline, if temperature difference overrun within the time of setting, then send the smooth or blocking alarm signal of ash discharge to alarm unit immediately; The too high employing level sensor of ash bucket dust stratification detects, if ash bucket dust stratification has exceeded setting value, sends the too high alarm signal of ash bucket dust stratification immediately to alarm unit; Alarm unit, after receiving any fault-signal that detecting unit sends, can automatically send sound and light alarm signal, be convenient to people's Timeliness coverage and handling failure.
As preferably, described sensor one, sensor two, sensor three and sensor four are large, the highly sensitive velocity sensor of the scope of testing the speed.
As preferably, described sensor five is highly sensitive temperature sensor.Sensor six is level sensor.
As preferably, described level sensor is passive nuclear level sensing device.
As preferably, described alarm unit comprises PLC.The fast response time of PLC, the requirement of stable and reliable operation, can be applicable to the environment that electric cleaner is installed and run.At present, the vibrated system of electric precipitation and insulator electric heating system are all widely used PLC and control, the controller of described alarm unit can with they public PLC, can be cost-saving.
The utility model has the advantage of:
The utility model is the automatic testing and alarm device of electric cleaner dust removing system fault, this device can detect any fault of electric cleaner dust removing system, and automatically send sound and light alarm signal immediately, be convenient to people's Timeliness coverage and handling failure, avoid fault spread; And the utility model does not change original equipment agent structure, easily implements, and the duration is short, instant effect is practical.
