Description
Technical field
The utility model relates to plate heat exchanger technical field, it is specifically related to a kind of heat exchange plate group and plate-type heat-exchange
Device.
Background technique
Plate heat exchanger is to pass through pad according to certain interval by multiple heat exchange plate groups (or being heat exchange plate component)
Piece compresses dismountable heat exchange equipment of composition.Plate heat exchanger is with small in size, occupied area is small, heat transfer efficiency is high, assembling
Flexibly, the advantages that heat loss is small；The plate heat exchanger occurred currently on the market is mostly liquid and fluid exchange, and can not be solved back
The problem of receiving the waste heat in flue gas of heating furnace；Therefore, the domestic waste heat generallyd use in air preheater recycling flue gas of heating furnace,
For being preheated to the air of burning, to improve heater efficiency.And air preheater is in actual application, not only
It is easy to appear the problems such as dew point corrosion failure, equipment are huge and investment is huge, and with the reduction of flue-gas temperature, air is difficult to
The caloric receptivity of flue gas is balanced, this makes the exhaust gas temperature of existing heating furnace substantially at 160~200 DEG C, still has more heat not
It is recovered；So for further recovery waste heat, it is necessary to absorb the condensation heat of flue gas with water or other liquid phase process media
Amount.
In order to solve Related Technical Issues existing in the prior art, research process of the present applicant in early stage

Nonmetallic heat exchange plate deformation occurs, not only bad for ensuring its mechanical performance, and nonmetallic heat exchange plate is easy to appear
The case where unbalance stress, even there is a situation where nonmetallic heat exchange plates to rupture when serious.
In addition, application No. is the patent documents of CN201380030370.3 to disclose a kind of be used in dehumidifier/air-conditioning system
The heat exchanger used, comprising: multiple diaphragm plate components, the multiple diaphragm plate component in substantially parallel structure it is facing with each other simultaneously
And be spaced to define therebetween the air gap, the air to be handled by the dehumidifier/air-conditioning system can flow through described
The air gap, each of described diaphragm plate component include: hardened structure, two films, each film faces the hardened structure
Opposite side and it is spaced apart to define therebetween the gap and at least one that liquid drier can flow through with the hardened structure
Desiccant discharge port, wherein each film has bottom part, and the bottom part is sealed to the hardened structure, makes
The liquid drier is forced through at least one described discharge port, thus be located at each film and the hardened structure it
Between the gap in form negative pressure.But the heat exchanger in this application is mainly used in dehumidification system, and structure is more multiple
It is miscellaneous, not only bad for reduction production cost, and it can not ensure its heat exchange efficiency, it is more difficult to for returning to fume afterheat
It receives.
