Description

Technical Field

[0001] The utility model relates to the field of chemical dust reduction equipment, in particular to a dust reduction device for safe production in the chemical industry. Background Art

[0002] The chemical production process refers to the production process of obtaining valuable products by chemically processing raw materials. Due to the diversity of raw materials and products and the complexity of the production process, tens of thousands of chemical production processes have been formed. Looking at the numerous chemical production processes, they are all organically combined by chemical (biological) reactions and several physical operations.

[0003] Since chemical plants generate a lot of dust during the production of chemical products, the dust will affect the environment around the chemical plants. At this time, dust reduction equipment is needed to remove the dust. There are two types of dust reduction equipment currently used in chemical plants. The first is to spray water mist in the air. The water mist can increase the weight of the dust in the air and let the dust fall to the ground to achieve the effect of dust reduction. However, the water mist dust reduction method can only be used to place the equipment far away from the chemical equipment to prevent the water mist from entering the chemical equipment and causing damage. The second is to use dust suction to suck the dust in the air into the equipment through a fan, and use a filter to collect the dust to achieve the effect of dust reduction.

[0004] However, when too much dust accumulates on the filter in the second dust reduction method, workers are required to clean the dust on the filter so that the device can continue to operate, which shortens the maintenance cycle of the device and requires workers to frequently disassemble the device to clean the filter.
