Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-temperature gas-liquid tube heat exchangers, in particular to an anti-blocking high-temperature gas-liquid tube heat exchanger. Background Art
[0002] The high-temperature gas-liquid tubular heat exchanger uses a specific pipe structure to allow the high-temperature gas and liquid to flow through the pipes on the inner and outer sides respectively, thereby realizing heat transfer from the high-temperature gas to the low-temperature liquid, achieving energy transfer and utilization. The existing high-temperature gas-liquid tubular heat exchanger has potential problems in the circulation of heat-conducting liquid during use. Specifically, the heat exchanger lacks a filtering structure to prevent clogging of the heat-conducting liquid.
