Plate heat exchanger

Abstract

The invention belongs to the technical field of heat exchange equipment, and particularly discloses a plate heat exchanger which comprises a heat exchange plate and a cover plate. One side of the heatexchange plate is provided with the cover plate. The positions, corresponding to a hot medium inlet, a hot medium outlet, a cold medium inlet and a cold medium outlet, of the four corners of the cover plate are provided with water holes. A three-way valve is rotationally connected into the water hole corresponding to the hot medium inlet. The upper side of the three-way valve communicates with afirst branch. The lower side of the three-way valve communicates with a second branch. The first branch communicates with the second branch. The second branch communicates with the hot medium inlet. Arotating cavity is formed in the middle of the first branch and internally rotationally connected with a water wheel. A group of blades are arranged on the periphery of the water wheel. An arc-shapedeccentric hole is formed in the water wheel. When the water wheel rotates, the heat exchange plate vibrates and accelerates the exhausting, and the heat exchange efficiency of the heat exchange plateis increased.

Description

technical field [0001] The invention belongs to the technical field of heat exchange equipment, in particular to a plate heat exchanger. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used . [0003] A heat exchanger is an energy-saving device that transfers heat between materials between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid temperature reaches the process The specified index is to meet the needs of the process conditions, and it is also one of the main equipment to improve energy utilization. The heat ex...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, solve the problem that after the heat medium of the existing plate heat exchanger flows in from the heat medium inlet, a large number of bubbles are likely to be generated in the heat exchange plate, which is difficult to discharge, which seriously affects the heat exchange efficiency of the heat medium, causing the plate heat exchanger To solve the problem of low heat exchange efficiency of the heat exchanger, a plate heat exchanger proposed by the present invention
