Pressure-bearing supporting type heat exchanger

Abstract

The invention relates to a pressure-bearing supporting type heat exchanger. The pressure-bearing supporting type heat exchanger comprises a heat exchanger body, the heat exchanger body is formed by assembling a first clamping plate, a second clamping plate and a heat exchange plate bundle, and the heat exchange plate bundle is formed by superposing a plurality of pressure-bearing supporting framework combination units. Each pressure-bearing supporting framework combination unit is formed by assembling a pressure-bearing supporting framework and heat exchange plates arranged on the upper face and the lower face of the pressure-bearing supporting framework. Under the condition that the body structure of the heat exchange equipment is not changed, the purpose and the function of the equipment can be changed by additionally arranging end sockets required by the working condition at the two ends, so that the heat exchanger is manufactured in an integrated manner and assembled and maintained in a modular manner, the manufacturing cost is reduced, the manufacturing, assembling and maintaining efficiency is improved, and the service cycle of the equipment is prolonged.

Description

technical field [0001] The invention relates to a heat exchanger, specifically a pressure-supported heat exchanger, which is widely used in petrochemical, metallurgy, electric power, shipbuilding, light industry, machinery, heating, air conditioning and other industries. It is the key development equipment advocated by the country for energy saving and emission reduction. Background technique [0002] The existing detachable plate heat exchanger sealing method basically adopts the soft sealing method, that is, each heat exchange plate is designed with a gasket groove structure, and the sealing between the medium and the medium and the medium is realized through the matching sealing gasket. A seal between the outside world. Usually, the sealing gasket is made of rubber material with a certain compression ratio greater than 20%, and the thickness is greater than the corrugation depth of the two adjacent heat exchange plates. The detachable plate heat exchanger is clamped by t...

AI Technical Summary

Problems solved by technology

[0005] 1. The heat exchange plates rely on their own stiffness to withstand the pressure from the heat exchange chamber, and have poor resistance to pressure fluctuations, unstable pressure bearing capacity, and poor pressure bearing effect;

[0006] 2. The temperature resistance range is small, and the temperature resistance effect is limited by the material process. If it is operated at high or low temperature for a long time, the sealing gasket is easy to age and has poor resistance to temperature fluctuations;

[0007] 3. The corrosion resistance is unstable, and the medium contacts the two materials of the plate and the gasket, which is easy to form potential difference corrosion;

[0008] 4. Defects are prone to occur during the material processing of the gasket, resulting in partial failure of the heat exchanger or accelerated aging and leakage;

[0009] 5. The application limitations are large, and it is not suitable for heat exchange of toxic and harmful media;

[0010] 6. During the assembly process, it is necessary to ensure high flatness and high precision, and uneven clamping will cause local leakage;

[0011] 7. Repeated disassembly will easily lead to premature failure of the gasket and increase maintenance costs;

Traditional heat exchangers are set based on their corresponding process materials and cooling and heating media, each has an independent structure, the manufacturing process is complicated, the product quality is unstable, and the manufacturing cost is high.
