Abstract

The invention aims to provide a high-pressure resistant lamella heat exchanger adopting round corrugated plates, which includes a shell, cover plates, a corrugated plate lathed bundle, flow guiding blocks and support plates, wherein the corrugated plate lathed bundle includes corrugated plates and is fixed in the shell through the support plates; the two ends of the shell are sealed by the cover plates; a shell side outlet and a shell side inlet are arranged in the shell; a plate side inlet and a plate side outlet are arranged in the cover plates; an annular zone between the shell and the corrugated plate lathed bundle is divided into a shell side inlet chamber and a shell side outlet chamber through the flow guiding blocks; the shell side inlet is communicated with the shell side inlet chamber; the shell side outlet is communicated with the shell side outlet chamber; angular holes are formed in the corrugated plate lathed bundle; and the plate side inlet is communicated with the plate side outlet through the angular holes in the corrugated plate lathed bundle. The high-pressure resistant lamella heat exchanger provided by the invention has the advantages of high pressure bearing capability, high heat exchange efficiency, compact structure, big heat transfer area in a unit volume, wide material selection range, wide application range, as well as simplicity in processing and installation.

Description

technical field

[0001] The invention relates to a heat exchanger in the technical field of enhanced heat exchange. Background technique

[0002] Plate heat exchangers are widely used in energy, power, heating, refrigeration and other fields due to their high heat transfer efficiency and compact structure. With the maturity of plate heat exchanger technology, it has replaced the traditional shell and tube heat exchanger in some fields. However, the existing rectangular plate heat exchanger generally has the problem of low pressure bearing capacity. In petrochemical and other common high-pressure fields, the application of plate heat exchangers has been greatly restricted. Developing a plate heat exchanger that can withstand high pressure and has a compact structure has broad application prospects in the field of energy and power. Although there are some fully welded plate and shell heat exchangers at present, their working pressure generally does not exceed 4.5MPa, and the...
