Abstract

A detachable heat exchanger plate bundle composed of all-welded plate tubes, including corrugated plates and inserts, and the corrugated plates have holes at their near ends respectively, and the holes are a medium inlet and outlet. A sealing gasket groove is set at the entrance and exit of the medium; the two corrugated plates are buckled together, and the convex corrugations on them are in contact with each other, and the surrounding strips are added, and welded together to form a fully welded plate tube. A channel for fluid circulation is formed in the tube; two of the plate tubes are stacked together, and a sealing gasket is fitted in the sealing gasket groove to form a plate bundle, and the channel formed between the plate tubes is another A channel for fluid circulation; the plate bundles are fixed together by bolts, thereby forming a detachable heat exchanger plate bundle. The invention solves the problem of easy blockage of plate bundles in actual work.

Description

technical field

[0001] The invention belongs to the technical field of design and manufacture of heat exchangers, in particular to a heat exchanger corrugated plate bundle, in particular to a detachable heat exchanger plate bundle composed of fully welded plate tubes. Background technique

[0002] According to different assembly forms, heat exchangers can be divided into two types: detachable and fully welded. The advantage of the detachable heat exchanger is that it is convenient to disassemble and assemble. The disadvantage is that the pressure bearing capacity is low, so it is suitable for heat exchange of low pressure, easy to scale, and high viscosity medium. The advantage of the all-welded heat exchanger is that it has high pressure and temperature resistance, and the disadvantage is that it cannot be disassembled, so it is impossible to clean the dust and dirt accumulated on the plates.

[0003] Plate heat exchangers are usually used in petroleum, petrochemical, coal...
