Pipe-plate type heat exchanger adopting foamy copper material

Abstract

The invention relates to a pipe-plate type heat exchanger adopting a foamy copper material. Multiple foamy copper plates are placed in parallel at intervals, and an S-shaped cooling water pipeline alternately crosses back and forth between the foamy copper plates, so that the foamy copper heat exchanger is formed and is arranged in a flue shell. When a flue gas flows in from one end of a flue andpasses through the foamy copper heat exchanger in the middle, the flue gas penetrates through the gaps between the foamy copper plates and the S-shaped cooling water pipe, one part of heat in the flue gas directly exchanges heat through the S-shaped cooling water pipe, and the other part of heat in the flue gas is transferred to cooling water through the foamy copper plates or stored in gap spaces of the foamy copper plates so as to be absorbed by cooling water; and the low-temperature flue gas subjected to heat exchange with the cooling water flows out from the other end of the flue. The heat exchanger is compact in structure, small in volume and high in heat exchange efficiency, and not only can be applied to recycling flue gas waste heat and water, but also can be applied to recyclingwater in other waste heat and waste gases.

Description

technical field [0001] The invention relates to a device for recovering waste heat and water in flue gas, in particular to a device for recovering waste heat and water in power plant boiler flue gas. Background technique [0002] With the development of society and the progress of industry, the energy crisis has become a major problem that all countries in the world must face and solve. This makes energy saving and emission reduction more important. The known heat exchanger equipment has problems such as low efficiency or large volume due to material and technical reasons. However, with the improvement of technology and level in recent years, various new materials have been used After being developed, these materials often have characteristics that other materials do not have, which provides conditions for the development of new heat exchanger equipment.

AI Technical Summary

Problems solved by technology

[0003] The traditional shell-and-tube heat exchanger has simple structure, mature technology, and wide application, but has disadvantages such as low heat transfer efficiency and large floor space.

The plate heat exchanger has high heat transfer efficiency and occupies less land, but has low pressure bearing capacity, large pressure loss, and is easy to leak and block.
