Described dust removing tube route more piece bend pipe is fixedly connected with in aggregates with straight tube, dedusting pipeline one end is connected with the discharging opening top of dryer, the other end is connected with the inlet scoop of cloth bag pulse dust collector, has a wind-supplying mouth on the straight tube tube wall that the dedusting pipeline links to each other with cloth bag pulse dust collector;
Described air compensation device comprises the secondary air channel that is located at dedusting pipeline wind-supplying mouth place, be provided with the benefit air-valve that is consisted of by circular slab valve, rotating shaft and swing arm in the secondary air channel, the circular slab valve is fixed in the rotating shaft, and the rotating shaft two ends are hinged on the tube wall of secondary air channel, and an end of mending air-valve is fixed with swing arm;
Described control device comprises electric pushrod and electrical control cubicles, and electric pushrod is hinged and connected with the swing arm of mending air-valve, and the input interface of electrical control cubicles is connected with electric pushrod with thermocouple respectively through wire with output interface.
Oven dry owner deduster of the present invention guard method:
When dryer is worked, detected the temperature that enters dedusting pipeline flue dust by the thermocouple real-time online;
When detected temperatures reached 65-75 ℃, electrical control cubicles was controlled electric pushrod the aperture of mending air-valve is increased gradually, reduces the temperature of the flue dust that enters cloth bag pulse dust collector;
The flue dust temperature that detects along with thermocouple constantly raises, and the degree of mending the air-valve unlatching increases thereupon, until all open; If the benefit air-valve is all opened rear flue dust temperature and still is higher than 80 ℃, then reduce hot-blast stove fuel is supplied with;
When the flue dust temperature that detects when thermocouple was lower than 65-70 ℃, electrical control cubicles was controlled electric pushrod the aperture of mending air-valve is reduced gradually, until close fully.
Beneficial effect: the present invention arranges thermocouple at dryer discharging opening place, can detect online at any time from the temperature of dryer flue dust that discharging opening is discharged; Set up air compensation device at the dedusting pipeline near the position of cloth bag pulse dust collector; Automatically open or close the benefit air valve according to predefined temperature range, the temperature when automatic stepless adjusting flue dust enters deduster as required, thus guarantee that its cloth bag pulse dust collector is not subjected to fire damage.It is simple in structure, and dependability is high, can effectively protect oven dry owner deduster, has widely practicality.
