Abstract
The invention relates to a heat exchange corrugated plate for a plate heat exchanger and for distributing evaporated liquid. The heat exchange corrugated plate can be used for various heat exchangers with plate sheets serving as main heat exchange faces and is widely applied to the refrigeration field, the chemical engineering field, the steel field and the like. Ripples are manufactured on the tapered planes or the skew surfaces, making contact with a heat exchange medium, of the plate sheets. The ripples can be of any curved surface shape, can be totally or partly arranged and can also be irregularly arranged. The plate sheets overlap layer by layer to form the heat exchange corrugated plate, the flowing volumes of two types of media where heat exchange needs to be conducted can be different, the partial volumes in the same channel can be different, resistance in the places with small volumes is increased so that media can be forced to flow to the places with large volumes, and then flow of media is evenly distributed in the width direction of the plate sheets, heat exchange of two types of media with the large physical parameter difference or the large flow difference can be efficiently processed, and heat exchange efficiency can be improved by more than 10%.
Description
Technical field
The present invention relates to a kind of plate type heat exchanger (changing hereinafter to be referred as plate) for distributing the heat exchange corrugated cardboard sheet (hereinafter to be referred as plate) of evaporated liquor, can be for removable, non-disconnectable formula, semi-detachable plate changes and other heat exchangers take plate as main heat-transfer surface.
Background technology
Plate changes in refrigeration, chemical industry, and the fields such as iron and steel have a wide range of applications, and one of them vitals is exactly plate.In the time that plate changes as an evaporimeter use, the medium that enters the need evaporation after house steward is in a liquid state and gaseous state two-phase, and this two-phase flow is evenly imported to each heat exchanger channels becomes one of key improving heat exchange efficiency.
In prior art, common solution is: the entrance at each passage is arranged distributor, utilize the small bore passage of distributor to increase the medium pressure drop of admission passage, to improve distribution effects, because length shorter (being generally several mm) and the length of the small bore passage of this type of distributor cannot be adjusted, the pressure drop forming is fixed, and is also partly to the improvement of distribution effects.
Summary of the invention
In order to overcome deficiency of the prior art, the invention provides a kind of plate type heat exchanger for distributing the heat exchange corrugated cardboard sheet of evaporated liquor.The present invention is mainly addressed the above problem by following proposal: before two-phase flow admission passage, near the house steward of plate, suppress small bore throttling passage, this throttling passage is generally arranged in along in house steward's circumferential direction, in principle, this throttling passage can be arranged a few, length can reach several 10mm, by certain the position perforate at this throttling passage, obtain the chock length of tapping to heat exchanger channels porch, because perforate can be in the optional position of throttling passage, the chock length of acquisition can be adjusted flexibly within the scope of several 10mm.And such perforate very easily completes by die-cut, small bore throttling passage is compressed on again on plate, without extra parts, so with low cost.
Adopt the plate of said structure superimposed layer by layer, form the plate type heat exchanger that band distributes evaporated liquor effect.Thereby reach and at low cost two-phase flow is evenly imported to each heat exchanger channels raising heat exchange efficiency.

The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the solution of the present invention is made to specific description.
Embodiment: be the plate 100 that is suppressed with the small bore crest throttling passage of inner ring 102 and outer ring 103 near circumferential direction house steward 101 referring to Fig. 1.
Fig. 2 is near the a-quadrant partial enlarged drawing of Fig. 1 house steward.Fig. 2 is presented at that certain position of small bore crest throttling passage 102 is die-cut ingate 104 and an outlet opening 105, and die-cut in certain position of small bore crest throttling passage 103 have ingate 106 and an outlet opening 107.Fig. 3 is the A-A section of Fig. 2.
Fig. 4 is the plate 200 that is suppressed with the small bore trough throttling passage of inner ring 202 and outer ring 203 near circumferential direction house steward 101.Fig. 5 is near the C region partial enlarged drawing of Fig. 4 house steward.Fig. 5 is presented at that certain position of small bore trough throttling passage 202 is die-cut ingate 204 and an outlet opening 205, and die-cut in certain position of small bore trough throttling passage 203 have ingate 206 and an outlet opening 207.Fig. 6 is the D-D section of Fig. 5.
Fig. 7 is the structural representation for distributing the plate of evaporated liquor to change after an assembling of the present invention.Be suppressed with the plate 100 of small bore crest throttling passage and superimposed with the plate 200 of small bore trough throttling passage near circumferential direction house steward, need the medium of evaporation to flow into house steward G1, the medium after evaporation flows out from G2.Processing medium flows into house steward L1, flows out from L2.
Fig. 8 is the structural representation that plate 100 and plate 200 are suppressed with respectively small bore crest and trough throttling passage after superimposed near circumferential direction house steward.The ripple struction of plate 100 and plate 200 has formed processing medium heat exchanger channels L and evaporative medium passage G (seeing Fig. 9), the sealing surface 108 of plate 100 and the sealing surface 208 of plate 200 are fitted each other, seal the entrance that enters evaporation channel G, force and enter the medium that plate changes the need evaporation of house steward G1 and 101 and flow into through the ingate 104 (204) of inner ring throttling passage 102 (202), flowing out the ingate 106 (206) through outer ring throttling passage 103 (203) again through inner ring throttling passage 102 (202) from outlet opening 105 (205) flows into, through outer ring throttling passage 103 (203), flow out and enter evaporative medium passage G from outlet opening 107 (207).Form throttling passage length from ingate 104 (204) to the outlet opening 107 (207) that enters evaporation channel, due to can be at the optional position of inner ring throttling passage and outer ring throttling passage die-cut entrance and outlet opening selectively, so throttling passage length is optional.The variation of pressure drop of throttling passage of flowing through can meet the medium of more characteristics, makes medium be flowed into each evaporation channel G through tapping by uniform distribution better.There are several variations by foregoing invention, can form the restriction effect of appropriate characteristics: the cross section of throttling passage can be circular or other shapes; Throttling passage can be unequal section; Total tube shape can be similar triangle or other shape.On near peripheral direction house steward, be suppressed with small bore throttling passage, can maximally utilise the variation of effective space formation chock length; Throttling passage can be made into helical form to increase the length of throttling passage.
Finally, it should be pointed out that above embodiment is only the more representational example of the present invention.Obviously, the invention is not restricted to above-described embodiment, can also have many distortion.
