Description

Technical Field

[0001] The utility model relates to the technical field of POLY process waste gas treatment, in particular to a solar cell POLY process waste gas treatment system. Background Art

[0002] With the continuous development of the photovoltaic industry, the demand for high-efficiency and low-cost photovoltaic cells is becoming increasingly urgent. For example, TOPCON solar cells, as a high-efficiency, mature and stable battery technology that can be put into mass production, have great market potential. It is expected that the market share of TOPCON solar cells will exceed 70% in 2024.

[0003] In the production process of TOPCON solar cells, the PE-poly process uses a large amount of silane gas and hydrogen as reaction gases, which will produce a large amount of process waste gas. Therefore, the treatment of waste gas is very important. During the waste gas treatment process, a large amount of silica dust will be generated after the combustion of silane. If this dust cannot be effectively cleaned, it will not only cause pipeline blockage, but also affect personnel safety.

[0004] At present, bag dust collectors are usually used to remove silica dust. However, the existing bag dust collectors use compressed air back-blowing and then manually seal the bags. Not only do the bags become hardened, which affects the service life of the bags, but the dust in the dust collector needs to be manually tied to the bags during the process of connecting the bags. Not only is the seal not tight, but the compressed air back-blowing will cause dust to escape, exposing people to the dust environment, which can easily cause health hazards. Utility Model Content
