GAS FLOW PIPELINE AND GAS TREATMENT APPARATUS

Title:

GAS FLOW PIPELINE AND GAS TREATMENT APPARATUS

Document Type and Number:

WIPO Patent Application WO/2020/192189

Kind Code:

A1

Abstract:

A gas flow pipeline and a gas treatment apparatus. The gas flow pipeline comprises an outer pipe (1), the outer pipe (1) having a first gas inlet (11) and a first gas outlet (12). The gas flow pipeline (100) further comprises an inner pipe (2) provided on the outer pipe (1) and having a same extension direction as the outer pipe. The outer pipe (1) is sleeved on the outer side of the inner pipe (2). The inner pipe (2) is communicated with the first gas inlet (11) and the first gas outlet (12) respectively to form a gas flow channel (4). A gas chamber (3) is formed between the outer wall of the inner pipe (2) and the inner wall of the outer pipe (1). The gas chamber (3) has an opening (31) facing a downstream direction of the gas flow channel. A pore channel (32) is formed on the sidewall of the inner pipe (2), and the pore channel has a gas inlet end communicated with the gas chamber (3) and a gas outlet end communicated with the gas flow channel (4). When reverse gas flows reach the opening of the gas chamber (3), some of the reverse gas flows enter the gas chamber (3) from the opening and are buffered by the gas chamber, and the reverse gas flows entering the gas chamber are discharged into the gas flow channel from the pore channel communicated with the gas chamber, such that the reverse gas flows are weakened.
