Heat exchange between the working medium heat exchange of similar temperament, such as gas-gas, liquid-liquid.For the working medium that the hot physical property difference in plate both sides is larger, such as
Heat exchange between solution-air, due to the convection transfer rate of hydraulic fluid side 2 orders of magnitude bigger than gas side convection transfer rate, and singly
The thermal capacity of position volume of liquid is nearly thousand times of gas, therefore the flow area plate type heat exchanger such as traditional form is not applied for
Heat exchange between solution-air.In the case where such solution-air exchanges heat, Patent No. 91210893.2 uses cold and hot medium channel face
The proportional method of product, it is 2 to meet working medium flow ratio:Heat transfer problem under 1 operating mode.Patent No.
200610010515.5 have further expanded the flow area of gas-liquid both sides on the basis of above-mentioned using not contour corrugated plating
Than achieving more preferable heat transfer effect.Particularly, regenerator both sides are flowed through in the Steam Power Circulation that the utility model is related to
Gas is identical with the mass flow of water, gas flow velocity can be caused too high and crushing increase using traditional plate type heat exchanger, and change
The thermal efficiency is not good.Design requirement can not still be met using the method for above two patent, to solve the problem, the utility model is set
A kind of new plate type heat exchanger is counted.
The content of the invention
In order to overcome the problem of above-mentioned prior art is present, the purpose of this utility model be provide it is a kind of be applied to vapour-
The low pressure loss plate type heat exchanger of liquid heat exchange, the utility model changes the flow of vapour side liquid, meets plate regenerator vapour-liquid matter
The equal application scenario of flow is measured, the problem of solving cold fluid and hot fluid thermal capacity mismatch and big drag losses.
In order to achieve the above object, the utility model is adopted the following technical scheme that：
A kind of low pressure loss plate type heat exchanger exchanged heat suitable for vapour-liquid, including heat exchanging segment 5, the heat exchanging segment 5 is by multiple plates
Composition is placed in the superposition of piece 6, is realized and fastened by fastening bolt 3；Multiple superpositions of plate 6 form gas runner 10 and flow channel for liquids 9,
Gas runner 10 and the adjacent distributions of flow channel for liquids 9, wherein forming 6 side-closeds of adjacent plate of flow channel for liquids 9, form gas
Side is unclosed between the adjacent plate 6 of runner 10；The top and bottom of the heat exchanging segment 5 respectively it is vertical with plate 6 be provided with into
Liquid pipe road 1 and drain pipe road 2, liquid working substance enter liquid by the feed liquor ligament 1-1 of input duct 1 and the junction of plate 6
Runner, drain pipe road 2 is flowed into after heat exchange from drain pipe gap 2-1, completes the heat transfer process of liquid working substance；The heat exchanging segment
5 sides are provided with gas drainage channel 4, the gas runner that gas working medium is entered in heat exchanging segment 5 by gas drainage channel 4；It is real
The distributary heat exchange of existing gas working medium and liquid working substance.
Gas working medium enters from the side of plate type heat exchanger, and the inlet area of gas working medium effectively increases, and then greatly
Increase the flow of gas working medium, while reducing crushing；It can additionally be met by adjusting the flow area of vapour-liquid side working medium
Vapour-liquid heat transfer problem under different operating modes.
Two adjacent plates in the plate 6, one of them rotates 180 ° of placements for another along center line.
Compared to the prior art compared with the utility model has advantages below：
1st, structural principle is simple：The utility model only needs to remove the part sealing of Conventional plate-type heat exchanger vapour side runner
Bar, while installing gas drainage channel additional, it is easy to process.
2nd, heat exchange efficiency is high, and drag losses is small：Vapour side working medium enters heat exchanging segment from the side of heat exchanger simultaneously, greatly increases
The inlet area of gas passage is added, has increased the flow of gas working medium, improved the heat exchange amount of vapour side, it is achieved thereby that vapour-liquid
Both sides thermal capacity matching problem.And the flow of gas is shortened to greatest extent, and the flow of vapour side working medium shortens can be effectively
Reduce drag losses.
3rd, main flow region of the present utility model forms network structure, and the flow area ratio of vapour-liquid runner can be as needed
Carry out flexible design, the applicability with height.
