Description
Technical field
This utility model relates to a kind of fiber bag precipitator detecting device, particularly a kind of fiber bag precipitator cloth bag condition checkout gear.
Background technology
Fiber bag precipitator is since coming out, owing to ash-clearing technology is advanced, process the features such as air quantity is big, floor space is little, purification efficiency is high, reliable operation, simple in construction, a little repair, be widely used in the industry-by-industries such as metallurgy, electric power, cement, chemical industry, pharmacy, food processing, building materials, timber processing. This cleaner unit efficiency of dust collection, up to more than 99%, is the perfect high-effective dust-removing equipment of a kind of comparative maturity.
Along with the continuous reinforcement to modern enterprise environmental requirement, the quantity of sack cleaner gets more and more, and size is also increasing, and the cloth bag quantity that monomer cleaner unit uses is on the increase, and several thousand the even large-scale cleaner unit of up to ten thousand cloth bags can be found everywhere easily.
The operation principle of fiber bag precipitator is that ash-laden gas is sucked cleaner unit, by being fixed on the filtering material on isolation card inside cleaner unit, is filtered down by grit, discharges from ash hole. The quality of sack cleaner dust removing effects depends primarily on takes for which kind of filtering material. The filtering material of sack cleaner adopts the cloth or felt that synthetic fibers, natural fiber or glass fibre be made at present mostly. Again these filtering materials are seamed into cylinder or pancake filter bag as required.
In order to improve the efficiency of dust collection of fiber bag precipitator, under the premise that cloth bag is intact, air pulse blowback rapping mode is generally adopted to carry out deashing operation. This work is the key factor that left and right cleaner unit catches dirt performance and operational situation. Deashing overlong time, by making the cloth bag of attachment dust layer while dust is fallen clearly to, very easily causes filter bag damage, and the serious cloth bag that also can cause comes off. If the deashing time is too short, the dust on filter bag falls to clearly not yet completely, just recovers filtration operation, cloth bag will be made to proceed operation with part dust layer, can affect its result of use. Current pulse dust cleaning cycle and deashing time length are all rule of thumb set in advance, can't adjust the rapping frequency of pulse backblowing in time according to the operating actual dust burdening situation of cleaner unit.
Current cloth bag leak-off pocket detection method mainly takes in the following manner: 1. device dust measuring instrument on the air channel of house outlet, and instrument detects that dust exceeding will be reported to the police, and this method is only known broken bag, but which bar cloth bag has leaked and can't detect. 2. take locellus sack cleaner is closed one by one to check.Locellus cleaner unit only can be adopted by the method. 3. the method taking pressure leakage detection, this method is provided funds big, and troublesome maintenance is rarely employed. 4. the method selecting fluorescent material leak detection, is mixed into quantitative fluorescence powder from cleaner unit import with dust and gas, then with the naked eye observes. The method is simple, but the cloth bag of blocking can not be detected. 5. taking indigenous method to check, it is seen that chimney over-emitting black exhaust, opening Box Cover checks cloth bag at once, if certain pure qi (oxygen) house dust is relatively more certainly leak-off pocket, but which cloth bag leakage is not known is.
The problem run as cloth bag blocking there is presently no effective detection method. How can grasp the service condition of cloth bag in equipment running process constantly, adjust pulse rapping frequency, promptly and accurately judge which cloth bag breakage, which cloth bag blocking, remind attendant to change, be improve dust collector efficiency, one of key of reduction production cost.
Summary of the invention
The purpose of this utility model is in that to provide a kind of device, can in the running of sack cleaner, data according to detection adjust pulse rapping frequency in time, detect which cloth bag is run-down in real time simultaneously, which cloth bag blocking, change the cloth bag needing to change in time, in order to improve efficiency of dust collection, reduce production cost.
The purpose of this utility model is achieved through the following technical solutions:
A kind of fiber bag precipitator cloth bag condition checkout gear of the present utility model, including casing, it is arranged on the air inlet of described casing side, the gas outlet of opposite side upper end, the ash-removing mouth of bottom, it is fixed in casing air inlet top, the card of bottom, gas outlet, described card has anyhow evenly distributed card hole, cloth bag is fixed on the downside of card, cloth bag muzzle is on card hole, pulse blowing pipe is arranged in card top through casing, the casing outer end of described pulse blowing pipe is fixed with pulse blowing valve, the pulse jet nozzle corresponding with card hole site it is fixed with under pulse blowing pipe in casing, it is characterized in that: in described casing, on card, both sides are respectively fixed with the left slide rail and right slide rail that are parallel to each other, it is vertical with left slide rail and right slide rail and be slidably connected that sliding beam is moved in hollow detection, pull line fixed pulley and the sliding beam runner of traction are fixed on described left slide rail and the card two ends in right slide rail centre position, pull line steady pin is fixed on described detection and moves on sliding beam, pull line hangs on described pull line fixed pulley and the sliding beam runner of traction, and it is fixed on described pull line steady pin, motor is fixed on described card and is connected with the sliding beam runner of traction, inside described left slide rail, it is fixed with toothed damping controls bend, sliding beam top localizer and sliding beam terminal locator it is respectively fixed at two ends with inside described right slide rail, move in sliding beam in described detection and be provided with damping unit.
Described damping unit is by the mobile sliding beam correspondence card hole site punching of detection the wind speed impeller bearing fixing on top, roll with wind speed impeller bearing and be connected wind speed impeller bracket porose above, the wind speed impeller axle being connected is fixed in upper end with described wind speed impeller bracket, the wind speed impeller being connected is fixed, with described wind speed impeller axle, in upper end, it is fixed on the antivibrator slide bar chute of the mobile sliding beam inner bottom part of detection, the antivibrator slide bar being connected with this antivibrator slide bar slide, control, near damping, the damping slide bar cam that bend one end is fixing at this antivibrator slide bar, at the antivibrator damping block that this antivibrator slide bar is fixing on the right side of wind speed impeller axle, it is fixed on the damping slide bar rivet on described antivibrator slide bar, it is fixed on the mobile sliding beam rivet on the mobile sliding beam of described detection, one end is fixed on damping slide bar rivet, the other end is fixed on the damping back-moving spring on mobile sliding beam rivet, it is fixed on the Speed sensing device composition on the mobile sliding beam of detection on the left of described wind speed impeller axle.
Operation principle of the present utility model is as follows: dusty gas enters the casing of fiber bag precipitator from air inlet, by being fixed on the cloth bag bottom card, discharges from gas outlet through card hole. Being hung over outside cloth bag by the dust of Bag filter, compression air, by pulse blowing pipe, blows out from pulse jet nozzle, blows in cloth bag along card hole, be attached to the staubosphere outside cloth bag along with falling down, and discharges from ash-removing mouth.
In order to monitor the state that cloth bag is in operation timely and accurately, it has been found that need the cloth bag changed, it is necessary to first gather cloth bag data in the updated.
