Embodiment 1

[0037] This embodiment is aimed at the plate heat exchanger used for heat exchange between the gas phase and the liquid phase in the prior art. The same as the conventional plate heat exchanger, the plate heat exchanger includes a heat exchange plate group, a sealing device, The inlet, heat exchange passage and outlet of the liquid phase medium, and the inlet, heat exchange passage and outlet of the gas phase medium.

[0038] In the prior art, it is often only concerned with the gas phase and liquid phase that can achieve heat transfer and the corrosion resistance to flue gas, while ignoring the relationship between the reliability of the heat exchange plate assembly and its heat exchange efficiency, specifically On the basis of the structure of the existing heat exchange plate group, if the contact area between the non-metal heat exchange plate and the metal heat exchange plate is too large, it will help to improve the assembly reliability of the heat exchange plate group, but...

Embodiment 2

[0045] as attached Figure 1-2 As shown, on the basis of Embodiment 1, this embodiment further introduces the structure of the heat exchange plate group 4:

[0046] The heat exchange plate group 4 also includes a second sealing plate 5, the second sealing plate 5 is connected to the first surface layer 62 and the second surface layer 63 respectively, and the second sealing plate 5, the first surface layer 62 , The liquid phase channel 1 is formed between the second surface layer 63, thereby ensuring the sealing performance of the liquid phase medium channel 1 inside the heat exchange plate group 4 on the one hand, and on the other hand, the first surface layer 62, the second surface layer 62, and the second surface layer can be sealed. The layer 63 and the velvet rib 64 provide a further fixing effect, which is beneficial to improving the assembly reliability of the heat exchange plate group 4 and the plate heat exchanger.

[0047] As another implementation of this embodiment...

Embodiment 3

[0049] As described in Embodiment 1, the velvet tendons 64 apply tension to the first surface layer 62 and the second surface layer 63 respectively, that is, the effect of the bearing capacity on the velvet tendons 64 all the time; as attached Figure 4 As shown, in this embodiment, on the basis of Embodiment 1 or Embodiment 2, the setting of the pile 64 is further introduced.

[0050] Described pile tendon 64 comprises the first rib and the second rib that are connected with each other; For the first rib, one end of the first rib is connected with the first surface layer 62, and the other end of the first rib is connected with the second rib. The surface layer 63 is connected; for the second rib, one end of the second rib is connected with the first surface layer 62 or the second surface layer 63, and the other end of the second rib is connected with the first rib.

[0051] Simultaneously, described hollow member 6 also comprises transverse rib, and described transverse rib i...

Abstract

The invention provides a plate heat exchanger and a production method of heat exchange plate groups of the plate heat exchanger. The plate type heat exchanger comprises a plurality of heat exchange plate groups (4), each heat exchange plate group (4) comprises a hollow part (6), each hollow part (6) comprises a first surface layer (62), a second surface layer (63) and a plurality of pile ribs (64), wherein the pile ribs (64) are arranged between the first surface layer (62) and the second surface layer (63), and any one of the pile ribs (64) is connected to one of the first surface layer (62)and the second surface layer (63) and correspondingly applying tensile force to the first surface layer (62) and the second surface layer (63). According to the plate heat exchanger and the productionmethod of the heat exchange plate groups of the plate heat exchanger, the production method of the plate heat exchanger and the heat exchange plate groups of the plate heat exchanger are provided, sothat the pressure-bearing capacity and the heat exchange efficiency of the heat exchange plate groups can be improved.

Description

technical field [0001] The invention relates to the technical field of plate heat exchangers, in particular to a production method of a plate heat exchanger and a heat exchange plate group. Background technique [0002] The plate heat exchanger is a detachable heat exchange device composed of a plurality of heat exchange plate groups (or heat exchange plate assemblies) pressed together by gaskets at certain intervals. Plate heat exchangers have the advantages of small size, small footprint, high heat transfer efficiency, flexible assembly, and small heat loss; most of the plate heat exchangers on the market today are liquid-to-liquid exchanges, and cannot solve the problem of recycling heating furnace smoke. The problem of waste heat in the gas; therefore, air preheaters are generally used in China to recover the waste heat in the flue gas of the heating furnace, which is used to preheat the air for combustion to improve the efficiency of the heating furnace. However, in th...
