Embodiment 1

[0044] Example 1: Reference figure 1 , figure 2 and image 3 , a gas-gas heat exchanger, comprising an upper plate sealing part 1 at the upper end and a lower plate sealing part 2 at the lower end, and several sealing parts arranged between the upper plate sealing part 1 and the lower plate sealing part 2 A heat exchange tube a, the plurality of heat exchange tubes a form a heat exchange tube bundle, a shell side fluid inlet 3 and a shell side fluid outlet 4 are arranged around the heat exchange tube bundle, and the shell side fluid inlet 3 and the shell side fluid outlet 4 are arranged The side plate 5 separated by the shell side fluid outlet 4;

[0045] Several layers of heat exchange tube orifice plates 6 are arranged on the side plate 5 in the vertical direction, and the heat exchange tube orifice plates 6 are made of corrosion-resistant PTFE material, and the heat exchange tube a passes through the heat exchange tube The heat pipe orifice plate 6 is arranged in the he...

Embodiment 2

[0054] Example 2: Reference figure 1 , figure 2 and image 3 , and the difference from Embodiment 1 is that the support member 112 is a tooth clip, that is, the cylindrical support part 1122 includes several tooth-shaped vacancies.

Embodiment 3

[0055] Example 3: Reference figure 1 , figure 2 and image 3 , the difference from Example 1 is that the second upper orifice plate 121 is lined with an upper plate anti-corrosion layer 123; the second lower orifice plate 221 is lined with a lower plate anti-corrosion layer 223, the upper The plate anticorrosion layer 123 and the lower plate anticorrosion layer 223 are made of PTFE material.

Abstract

The invention discloses a gas-gas type heat exchanger, and belongs to the technical field of heat exchange equipment. The gas-gas type heat exchanger comprises an upper plate sealing part located at the upper end, a lower plate sealing part located at the lower end, and a plurality of heat exchange tubes arranged between the upper plate sealing part and the lower plate sealing part. The heat exchange tubes form a heat exchange tube bundle. A shell pass fluid inlet and a shell pass fluid outlet are formed around the heat exchange tube bundle. A side plate used for separating out the shell pass fluid inlet and the shell pass fluid outlet is further arranged. The gas-gas type heat exchanger further comprises middle corrosion-resistant heat exchange tube pore plates. The gas-gas type heat exchanger is reasonable in structure, the supporting strength of the upper plate sealing structure to the heat exchange tubes is high, the lower plate sealing structure and lower pore plates form a buckling connection structure by means of the heat exchange tubes, the heat exchange tubes can be restrained in times of shrinkage, and shrinkage of the heat exchange tubes can be prevented.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a gas-gas heat exchanger. Background technique [0002] With the depletion of oil and coal, energy issues are becoming more and more prominent in front of people. In addition to the development of new energy sources, the conservation and reuse of existing energy sources have also become the focus of people's research. [0003] In energy utilization technology, a heat exchanger is a device for exchanging heat between hot and cold fluids without direct contact. The tube-type gas-gas heat exchanger has a wide range of applications in the fields of coal-fired boilers, waste incineration power generation, etc. Applications. [0004] In the prior art, only metal plates are often used to separate the flue gas, which will easily cause corrosion of the plates after a long time, and the seals are also prone to failure when exposed to the flue gas environment for a long tim...
