Description
Technical field
The utility model relates to a kind of spiral-plate heat exchanger structures for low flow velocity.
Background technique
Spiral heat exchanger has the advantages that small in size, facility compact, heat transfer efficiency are high, metal consumption is few, but due to
Roll bending plate tolerance system (minimum is generally 500mm), when flow is smaller, material fails that heat-transfer surface is made full use of to exchange heat, and leads
Heat exchanger is caused to fail to reach due heat transfer effect, practical heat exchange area greatly reduces.
It is as shown in Figure 1 traditional spiral-plate heat exchanger structure, when flow is smaller, the heat exchange area that material can utilize is only
There is sub-fraction, heat exchanger area is caused to waste.
Utility model content
Purpose of the utility model is to solve defect in the prior art, heat exchange can be made full use of by providing a kind of material
Face exchanges heat, and the spiral-plate heat exchanger structure for low flow velocity of heat utilization ratio is improved, to solve to exist in the prior art
The problem of.
To achieve the above object, the technical solution of the utility model is as follows:
A kind of spiral-plate heat exchanger structure for low flow velocity, including shell, the both ends of the shell are provided with air inlet
And gas outlet, several overhead gage and lower baffle plate are provided in the shell, and the upper end of the overhead gage is fixed on the interior of shell
On top surface, there are gap, the lower end of the lower baffle plate is fixed on the inner bottom surface of shell the inner bottom surface of lower end and shell, upper end with
There are gap, the overhead gage and the interlaced setting of lower baffle plate, the overhead gage and lower baffle plates to tilt and set for shell inner top surface
It sets.
In order to further realize the utility model, the first secondary baffle is provided on the two sides of the overhead gage.
In order to further realize the utility model, the second secondary baffle is provided on the two sides of the lower baffle plate.
In order to further realize the utility model, the overhead gage and lower baffle plate are relative to horizontal tilt angle
30°。
Beneficial effect
The utility model, which is applicable in, is less than 4m with flow3The case where/h, by being provided with inclined overhead gage and lower baffle plate, one
Aspect can reduce runner, on the one hand can increase stroke, it can be achieved that in the case where small flow, material can make full use of heat-transfer surface into
Row heat exchange, inclined baffle can further increase stroke, improve heat utilization ratio；In addition, by be provided with the first secondary baffle and
Second secondary baffle, when passing the gas through the space between adjacent overhead gage and lower baffle plate, positioned at the space the first secondary baffle and
Second secondary baffle is interlaced, further increases stroke, heat-transfer surface is made full use of to exchange heat, improve heat utilization ratio.
