Detailed description of the invention
In order to illustrate the technical solution of the embodiments of the present invention more clearly, required use in being described below to embodiment
Attached drawing be briefly described, it should be apparent that, drawings in the following description are only some embodiments of the invention, for this
For the those of ordinary skill of field, without creative efforts, it can also be obtained according to these attached drawings others
Attached drawing.
Fig. 1 is the external overall structure figure of the embodiment of the present invention；
Fig. 2 is the schematic diagram of internal structure of the embodiment of the present invention.
Specific embodiment
Referring to figs. 1 to Fig. 2, the present invention is a kind of thermoelectric (al) type gas gas plate heat exchanger, including shell with interior cavity 1, institute
It states shell 1 and is equipped with the cold flow entrance 11 and hot-fluid entrance 12 communicated with cavity, the cold flow entrance 11 and hot-fluid go out
The interlaced setting of entrance 12.The cold flow entrance 11 of the shell 1 and the surface of hot-fluid entrance 12 are arranged to boss-shaped,
External opening is convenient in the setting of the opening of cold flow entrance 11 and hot-fluid entrance 12, is arranged to boss-shaped, there is shell 1 more
It is carried out conducive to the heat exchange of gas.The heat exchange being connected with cold flow entrance 11 and hot-fluid entrance 12 is equipped with inside the shell 1
Module 2, the heat exchange module 2 include several heat exchange plates 21 for folding fixation, form gas between the adjacent heat exchange plate 21
Body circulation passage 3 is respectively mounted the electric heating piece 4 with pyroelectric effect in each heat exchange plate 21, and the thermoelectric slice 4 passes through energization
Conducting wire 5 and power supply are connected.All electric heating pieces 4 in each heat exchange plate 21, which are arranged in parallel, to be connected on power supply, after powering on, electricity
Backing 4 works.
Traditional gas gas plate heat exchanger, when high-temperature gas processed needs to be down to environment temperature or less even subzero
When, the cold source gas temperature of the heat exchanger other side needs 5 degrees Celsius of arrangement above lower than target temperature in more than ten degrees Celsius, and this
Thermoelectric (al) type gas gas plate heat exchanger, cold source gas temperature do not need temperature and so limit, as long as but 4 cold end side of electric heating piece
Temperature is maintained at room temperature and can achieve the goal.This thermoelectric (al) type gas gas plate heat exchanger has by installing among heat exchange plate 21
There is the electric heating piece 4 of pyroelectric effect, electric heating piece 4 is connected to power supply, by the pyroelectric effect of electric heating piece 4, processed gas can be made,
It is not required to consider the temperature level of other side gas, overcomes when original traditional gas gas plate heat exchanger exchanges heat and need to keep two
Kind of the recuperated gas temperature difference in a certain range the shortcomings that, and realize processed gas and reach required temperature not by another
The limitation of the temperature of side gas.Not only changed in terms of heat exchange function by improved thermoelectric (al) type gas gas plate heat exchanger
It is kind, strong guarantee is also obtained in terms of control, while great contribution is also made in terms of maintenance operation, energy conservation and environmental protection.Respectively
Requirement is up to state standards or professional standard and actual requirement, compact-sized, and figure is opposite to be greatly reduced, and the processing is simple,
