Description

A kind of spiral-plate heat exchanger structure for low flow velocity
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.

Specific embodiment
The utility model is further described in detail with reference to the accompanying drawing, these attached drawings are simplified signal Figure, only illustrates the basic structure of the utility model in a schematic way.
Embodiment one
As shown in Fig. 2, the utility model includes shell 1 for the spiral-plate heat exchanger structure of low flow velocity, in which:
The both ends of shell 1 are provided with air inlet 11 and gas outlet 12, and several overhead gage 2 and lower block are provided in shell 1 Plate 3, the upper end of overhead gage 2 are fixed on the inner top surface of shell 1, the inner bottom surface of lower end and shell 1 there are gap, lower baffle plate 3 Lower end is fixed on the inner bottom surface of shell 1, and there are gap, overhead gage 2 and lower baffle plate 3 are interlaced for upper end and 1 inner top surface of shell Setting, overhead gage 2 and lower baffle plate 3 be obliquely installed, and overhead gage 2 and lower baffle plate 3 are 30 ° relative to horizontal tilt angle, It is provided with the first secondary baffle 21 on the two sides of overhead gage 2, the second secondary baffle 31 is provided on the two sides of lower baffle plate 3.
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.
The foregoing is merely the better embodiment of the utility model, the utility model is not limited to above-mentioned embodiment party Formula, there may be the structural modifications that part is small in implementation process, if various changes or modifications to the utility model are not The spirit and scope of the utility model are detached from, and are belonged within the scope of the claims and equivalents of the utility model, then originally Utility model is also intended to encompass these modification and variations.
