Row-line type integrated jacket pipe heat exchanger detachable scale clean structure

Abstract

The invention discloses a row-line type integrated jacket pipe heat exchanger detachable scale clean structure, includes a transversely disposed jacket pipe composed by connecting an U shaped connection pipe to a C shaped connection pipe in sequence, and a short pipe, a coolant inlet pipe, a coolant exit port, a water inlet pipe, a water outlet pipe and a footing. The connector between the two interfaces of the U shaped connection pipe and the left end of the jacket pipe is a screw connection structure, the connector is locked in common situation that is in sealed connection situation. After a period of time operation, heat exchange efficiency is reduced because of accumulated scale, so proceeding maintenance of cleaning scale in shutdown situation, first unscrewing related connector and demounting the u shaped pipe and cleaning inner pipe of the jacket pipe, then installing the u shaped connection pipe and the operation is recovered. The invention can install and uninstall the u shaped connection pipe by connector of screw connection structure that is convenient for physical scale cleaning operation without drawing off coolant which reduces cost of scale clean maintenance greatly.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a casing heat exchanger with a cleaning window. Background technique [0002] When the casing heat exchanger is in operation, because the inner pipe of the casing has long-term flow of hot water medium, scale is easy to accumulate on the inner wall, and the scale layer directly reduces the heat transfer efficiency of the casing heat exchanger. Under normal circumstances, the casing heat exchanger needs to be cleaned for a period of time after running for a period of time. The prior art product must be disassembled as a whole in a shutdown state, and the limited cleaning of the inner tube can only be done after the refrigerant is released. Due to the structure, it is difficult and costly to clean the dirt. Especially for the spiral casing heat exchanger, the inner and outer tubes are in a helical nesting structure, and the bent inner tube cannot be effectively physically removed after fouling....

AI Technical Summary

Problems solved by technology

[0003] The present invention mainly aims at the technical problem that the prior art products are difficult to physically remove the fouling of the inner tube, and proposes a detachment and cleaning structure of the determinant integrated casing heat exchanger with simple structure, reliable connection, convenient disassembly and easy cleaning operation
