Description

Technical Field

[0001] The utility model belongs to the field of waste gas treatment, in particular to an industrial waste gas dust removal device. Background Art

[0002] Industrial dust waste gas mainly comes from the mechanical crushing and grinding of solid materials, the mixing, screening, packaging and transportation of powdered materials, the smoke generated by the combustion of materials, and the oxidation and condensation of steam generated when materials are heated in the air. When industrial dust waste gas is discharged directly into the atmosphere without treatment, it will pollute the surrounding atmospheric environment and cause direct and indirect harm to the health of the surrounding people. Specifically, these substances enter the human body through the respiratory tract, some of which directly cause harm, and some have an accumulation effect, which will more seriously endanger human health. Different substances will have different effects on the human body. For example, toxic metal dust and non-metallic dust will cause poisoning and even death after entering the human body. Long-term inhalation of dust can also lead to symptoms of pneumoconiosis and pneumonia. In order to protect the atmospheric environment, industrial dust waste gas must be treated by waste gas treatment facilities to meet the standards before it can be discharged.

[0003] Existing waste gas dust removal equipment consists of a box and a filter. Usually, the waste gas treatment box is mostly rectangular or cylindrical. The waste gas is discharged into the box, and the waste gas is purified by the purification liquid inside the box. At the same time, the purified waste gas enters the filter, and the filter achieves the purification effect of the waste gas, so that the waste gas is discharged into the air after purification, achieving the waste gas treatment effect. Most of the existing waste gas dust removal equipment has only one set of filter components for filtering harmful substances. When there are too many harmful substances attached to the filter in the filter component, the filter needs to be replaced. When replacing the filter, the existing waste gas dust removal equipment needs to suspend the operation of the equipment and then replace the filter. However, this replacement method takes a long time, which will inevitably affect the efficiency of industrial production in the long run. Utility Model Content
