Description

Smoke conveying device with lifting type smoke deflector

Technical Field

The utility model relates to a smoke and dust conveyor who contains over-and-under type smoke and dust divertor belongs to coke oven environmental control technical field.

Background

The coke oven is a main device of a coking enterprise, the coke oven adopts a coking chamber method to fire coke, and the size and the hole number of the coking chamber arranged in each coke oven are different for each coking enterprise due to different coke productivity. Each carbonization chamber is respectively provided with a furnace door at the coke side and the machine side, and a certain amount of smoke and dust can escape from the upper part of a furnace door of the carbonization chamber and enter the atmosphere in the coke pushing and coal charging processes, thereby causing harm to the environment. The flue gas emitted from the furnace door is commonly called furnace end flue, and in recent years, because the requirements of environmental governance work are strict, various coking enterprises are successively provided with flue gas collecting and processing systems for governing the escape of the furnace end flue gas.

Furnace end cigarette dust collecting and processing system mainly includes: the device comprises a smoke dust collecting cover, a smoke dust collecting pipe, a smoke guide vehicle, a dust removal belt ventilation groove, a dust remover, an induced draft fan and a chimney. The process flow is as follows: furnace end smoke which escapes from the furnace door is sucked by the fan, enters the smoke dust collecting cover and is respectively exhausted after passing through the smoke dust collecting pipe, the smoke guide vehicle, the dust removing belt ventilating groove, the dust remover, the fan and the chimney.

The dust removal belt ventilation groove structure in the above-mentioned flow is: the square groove welded by steel plates, the left and right plates and the bottom plate of the square groove are welded by steel plates, the top of the square groove is open, and a belt covers the square groove. The smoke dust collecting cover is connected with one end of the smoke dust collecting pipe and is fixed on the coal-charging coke pusher, the smoke guide vehicle is connected with the other end of the smoke dust collecting pipe, the other end of the smoke guide vehicle is connected into the dust removing belt ventilating groove, and the smoke guide vehicle synchronously travels along with the coal-charging coke pusher. The smoke guide vehicle has the effects that smoke in the smoke collecting pipe is guided into the dust removal belt ventilation groove, the belt is lifted in front of the smoke guide vehicle when the smoke guide vehicle walks, and the belt covers the top of the dust removal belt ventilation groove in the back of the smoke guide vehicle.

It can be seen from the above that the top of the dust removal belt ventilation groove is only sealed by covering the top with the belt, so that a certain gap can be formed between the belt and the top of the dust removal belt ventilation groove practically, and the sealing cannot be too tight. On the other hand, the connection between the smoke guide vehicle and the belt is realized by lifting the belt in front of the vehicle and covering the belt behind the vehicle through the travelling wheels of the smoke guide vehicle, and the sealing can not be realized at the position. Above-mentioned two points just caused dust removal belt ventilation groove to leak out seriously, caused the suction of fan to reduce a lot here, through on-the-spot actual measurement: fan suction when 10 ten thousand Nm/h, can only record about 4 ten thousand Nm/h in smoke and dust suction hood department, half above amount of wind is all revealed from the clearance between belt and the ventilation groove and the clearance between leading cigarette car and the ventilation groove, makes furnace end cigarette dirt collection processing system's ability greatly reduced, leads to during the smoke and dust that the furnace gate was emitted still partial diffusion to the air, causes the pollution to the environment. The problem restricts the coking enterprises and is not solved so far. Therefore, the smoke conveying device with the lifting smoke deflector is designed to solve the problems.
