Description

Technical Field

[0001] The invention relates to the technical field of environmental protection equipment, in particular to a dust removal structure for a molybdenum oxide rotary kiln. Background Art

[0002] The dust removal structure used in molybdenum oxide rotary kiln usually adopts bag dust collector, which can let dust-containing gas enter the dust collector from the air inlet. Large dust particles fall directly into the ash hopper due to gravity. When the finer dust rises with the air flow through the filter bag, the dust is retained on the outer surface of the filter bag. The purified gas is discharged through the air outlet. It can also remove dust of various particle sizes and has a good collection effect on fine dust, reducing the harm of dust to the environment and human health. It can also play a role in recovering valuable dust substances in industrial production. It has certain economic value, ensures the cleanliness and safety of the production process, and avoids safety hazards caused by dust accumulation.

[0003] The Chinese patent with publication number CN108465306B discloses a bag dust collector, which includes a dust removal chamber, a purification chamber, an ash hopper, and a support leg. A first partition is provided between the dust removal chamber and the purification chamber, and a second partition is provided between the dust removal chamber and the ash hopper. The first partition is provided with a plurality of first through holes, and the second partition is provided with a plurality of second through holes; a straight tube is fixed between each first through hole and the corresponding second through hole, and a plurality of rows of ventilation holes are provided on the tube wall of each straight tube; a frame is provided in each straight tube, and a filter bag is sleeved on each frame; an air inlet is provided on the side wall of the dust removal chamber, an air outlet is provided on the top of the purification chamber, and an ash discharge valve is provided at the bottom of the ash hopper. The bag dust collector provided by the present invention realizes that the dust-laden airflow will not affect the ash hopper after entering the dust removal chamber, and will not cause "secondary dust" to the dust originally deposited in the ash hopper.

[0004] The dust chamber and ash hopper of the existing bag filter are completely connected. As a result, when the dust-laden air enters the dust chamber, the dust on the three sides of the ash hopper will be lifted, causing the phenomenon of "secondary dusting". The dust will be blown to the filter bag again, which will reduce the dust removal efficiency and increase the working time of dust removal. In order to prevent dusting, the structure of the dust collector is generally changed, such as increasing the height of the dust chamber so that the airflow keeps a certain distance from the ash hopper after entering the dust chamber, or separating the dust chamber and the ash hopper to a certain extent. Although it can reduce the impact of "secondary dusting", it will cause the gas flow rate passing through the dust collector per unit time to decrease, greatly reducing the dust removal efficiency. If the bottom of the ash hopper is blocked, it needs to be cleared manually, which reduces safety.

[0005] Therefore, a dust removal structure for a molybdenum oxide rotary kiln is needed to solve the problem that while reducing the impact of "secondary dust", the gas flow through the dust collector per unit time is reduced, which greatly reduces the dust removal efficiency and low safety.
