Abstract
The utility model discloses a kind of gas heat exchanger plates convenient for deashing, including unilateral salient point and unilateral plate, the side of the unilateral side plate is plate, the other side is equipped with the unilateral salient point, unilateral salient point includes short strip salient point and high circular point shape salient point, the high circular point shape salient point is movably connected on short strip salient point, and when two pieces of unilateral flat plate splicings, and the high circular point shape salient point on respective side is connected with each other.The utility model can effectively prevent the deformation containing grey side gas flow, and when design calculating, improve the flow velocity containing grey side, increase ability of the gas from cleaning；Since clean side is salient point, unilateral heat transfer coefficient itself is higher, and design artificially increases the design current velocities of flat sides when calculating, and solves that conventional panel heat exchanger plate pressure drop is low, but also low problem, heat exchange efficiency can be improved 10% or more to heat exchange efficiency.
Description
Technical field
It is specifically a kind of to be commercially used for gas and gas the utility model relates to a kind of heat exchanger plate convenient for deashing
Between heat exchange or waste heat recycling and be convenient for deashing gas plate-type heat exchanger slab.
Background technique
During reducing energy consumption, the case where high-temperature dust-containing flue gas needs waste heat to recycle inevitably is encountered, in hot fume
Dust-laden be easy to cause heat exchanger to block.
For at this stage, traditional herringbone corrugated plating or salient point plate can not prevent equipment scaling from blocking, and deashing compared with
For difficulty；And the plate plate deashing to conduct heat is simple, but heat exchange efficiency is low, and must have supporting element between channel, and prop up
Support member becomes the severely afflicated area of dust stratification.Therefore, it is simple and novel to need a kind of structure type for ash-laden gas waste heat recycling field, heat transfer effect
Rate height and the convenient heat exchange plate of deashing.
Summary of the invention
The purpose of this utility model is directed to the deficiency of traditional flip's corrugated plating or salient point plate, and heat exchanging plate is changed
Into keeping its heat transfer efficiency high and deashing be convenient.
The technical scheme adopted by the utility model is that: a kind of gas heat exchanger plate convenient for deashing, including unilateral salient point
With unilateral plate, the side of the unilateral side plate is plate, and the other side is equipped with the unilateral salient point, and unilateral salient point includes short length
Bar shaped salient point and high circular point shape salient point, the high circular point shape salient point are movably connected on short strip salient point, and two pieces of unilateral side are flat
When plate splices, the high circular point shape salient point on respective side is connected with each other.
Further, the short strip salient point is connected with high circular point shape salient point by thread forms.
It further, is in triangle arrangement between the unilateral salient point；And preferably positive triangle arranges.
Further, it is attached in the form of electric resistance welding spot welding between the high circular point shape salient point.
Further, the right and left of the heat exchanger plate is to a direction backfin side, and upper and lower both sides are to reversed backfin side.
The principles of the present invention and effect are as follows:
This heat exchanger plate side is plate, and flat sides are complete square ducts；The other side is salient point, heat exchanger plates it is convex
Point is short strip and high round composition, and high circular point shape is to be connected through a screw thread with short strip；Pass through short strip angle
Degree transformation is to control the pressed contraction of heat exchange plate, to guarantee the flatness of overall heat exchange plate；Pass through high circular point shape
Die change adjust unilateral bump height, guarantee that the channel plate spacing of ashless side is adjustable, to guarantee the heat exchange of salient point side
Efficiency.
Plate sidles dusty gas, and salient point sidles clean gas；The salient point and salient point of two panels heat exchanger plates use resistance spot weld
Weldering, the salient point for selecting postwelding is both plate support and the plate stay bolt of dusty gas side of clean gas side, is effectively prevent containing ash
The deformation of side gas flow solves the problems, such as that flat sides need supporting element.
The salient point and salient point of heat exchanger plates salient point side are arranged at positive triangle, referring to the positive triangle comb method of tubular type, positive triangle
The comb method heat exchange efficiency highest of shape increases the heat exchange efficiency for having salient point side；
The design current velocity for increasing flat sides when design of heat exchanger, in the case where high flow rate, dusty gas has from cleaning
Ability also increases the heat exchange efficiency of flat sides；
Experiments have shown that: above improve solves the problems, such as that classic flat-plate heat exchanger heat exchange efficiency is low, and heat exchange efficiency can be improved
20%；
The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description
In become obvious, or recognized by the practice of the utility model.

Fig. 2 is the A-A cross-sectional view of Fig. 1.
Fig. 3 is the partial enlarged view of Fig. 2.
Fig. 4 is the partial enlarged view of Fig. 1.
In the figure, it is marked as 1 is unilateral salient point, 2 be unilateral plate, and 1-1 is short strip salient point, and 1-2 is that high circular point shape is convex
Point.
Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
As shown in Figures 1 to 4, a kind of gas heat exchanger plate convenient for deashing comprising unilateral salient point 1 and unilateral plate 2,
The side of the unilateral side plate 2 is plate, and the other side is equipped with the unilateral salient point 1, and unilateral salient point 1 includes short strip salient point
1-1 and high circular point shape salient point 1-2, the high circular point shape salient point 1-2 is movably connected on short strip salient point 1-1, and two pieces of lists
When the flat plate splicing of side, the high circular point shape salient point 1-2 on respective side is connected with each other.
This heat exchanger plate is by cutting into the stainless-steel sheets of uniform sizes, unilateral convex by one-step mould companding shaping
Point 1 is arranged at positive triangle, and geomery is consistent, and angle is different；The channel of the flat sides composition of unilateral plate 2 is rectangular square tube
Road, no support.Heat exchanger fin the right and left is to a direction backfin side, the upper and lower reversed backfin side in both sides, then presses above-mentioned aligned transfer.It changes
The high circular point shape salient point and high circular point shape salient point of backing use electric resistance welding spot welding, and the salient point for putting postwelding is both the plate of clean gas side
Piece support, and be the plate stay bolt of dusty gas side.
Then the upper and lower ends also full weldering of overlap joint two-by-two, is made sealing, the orthogonal heat exchange core body of gas traffic direction,
The plate of heat exchange core body sidles dusty gas, and salient point sidles clean gas, while effectively improving heat exchange efficiency, is convenient for deashing.
The basic principles and main features and advantage of the utility model have been shown and described above.The ordinary skill of this field
Personnel are not it should be appreciated that above-described embodiment limits the protection scope of the utility model, all use equivalent replacements etc. in any form
Mode technical solution obtained, falls in the protection scope of the utility model.
