Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, and more specifically, particularly to an automatic purification device for waste gas from an industrial furnace. Background Art

[0002] An industrial furnace is a thermal equipment that uses heat from fuel combustion or electrical energy conversion to heat materials or workpieces in industrial production. Industrial furnaces are often used in the production process. Common industrial furnaces use coal or coke as fuel, and coal or coke will produce certain exhaust gas after combustion. The exhaust gas is discharged into the atmosphere through the chimney, causing serious environmental pollution. Therefore, it is necessary to use an automatic exhaust gas purification device to treat the exhaust gas discharged from the industrial furnace.

[0003] However, there are various types of waste gas treatment devices in the prior art. For example, utility model patent CN206730774U relates to an industrial furnace waste gas treatment device. The utility model achieves the waste gas treatment effect by providing a liquid filter housing, a secondary filter device, an air inlet pipe, a filtrate layer, an air outlet pipe and a transmission pipe. The sulfur dioxide in the industrial furnace waste gas is effectively eliminated by sodium hydroxide solution, and the smoke and dust removal effect is ideal, thereby avoiding serious air pollution caused by the waste gas of the industrial furnace, thereby protecting human health and being more environmentally friendly.

[0004] Although the industrial furnace waste gas treatment device can effectively purify the waste gas discharged from the industrial furnace, the filter plate structure in the device is a fixed structure, which is not convenient for disassembly, resulting in impurities clogging the filter plate after long-term use. When it cannot be cleaned, the purification effect of the filter plate structure is affected, which is not conducive to the treatment of waste gas generated by the industrial furnace. In order to avoid this phenomenon, it is necessary to design an automatic industrial furnace waste gas purification device. Utility Model Content
