Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field related to heat exchangers, and particularly relates to a spiral plate heat exchanger with a side-inlet and side-outlet structure. Background Technique
[0002] A spiral plate heat exchanger is an efficient heat exchange device. It is formed by rolling two parallel metal plates into two spiral channels. The cold and hot fluids exchange heat through the spiral plate walls. This design of the heat exchanger causes the fluids to form a spiral flow in the channels, increasing the contact area between the fluids and the metal plate walls, thereby improving the heat transfer efficiency. The spiral plate heat exchanger can be of a detachable or non-detachable type. Among them, the non-detachable structure has better sealing performance and is suitable for heat exchange of highly toxic, flammable, explosive or precious fluids. The detachable structure is convenient for mechanical cleaning and is suitable for heat exchange of viscous or sediment-containing liquids. However, it still has the following disadvantages in actual use:
[0003] When the spiral plate heat exchanger works, usually the liquid to be heat-exchanged is conveyed through the top pipeline and a circumferential pipeline, and the liquid for heat exchange is conveyed through the bottom pipeline and a circumferential pipeline. During the working process, the flow path of the liquid to be heat-exchanged is limited, and the heat exchange effect is not good enough.
[0004] When the spiral plate heat exchanger works, when the liquid for heat exchange and the liquid to be heat-exchanged flow, the flow directions are opposite, and they are conveyed between the spiral plates through a single pipeline, which easily causes uneven liquid flow during the heat exchange process and the heat exchange effect is not good enough. Content of the Utility Model
[0005] The purpose of the utility model is to provide a spiral plate heat exchanger with a side-inlet and side-outlet structure. By setting a heat exchange shell, a liquid infusion cavity and a centralized cover, the problems that the flow path of the liquid to be heat-exchanged is limited and the heat exchange effect is not good enough when the spiral plate heat exchanger works, and the liquid flow is uneven and the heat exchange effect is not good enough when directly conveyed through a single pipeline are solved.
[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0007] The utility model is a spiral plate heat exchanger with a side-inlet and side-outlet structure, including a heat exchange shell, a liquid infusion cavity and a centralized cover. The centralized cover is fixed at the top of the heat exchange shell. The bottom of the heat exchange shell is fixedly communicated with the liquid infusion cavity. A homogenizing plate is fixed on the inner wall of the liquid infusion cavity. Dispersing holes are uniformly and penetratingly arranged in the homogenizing plate. A spiral cavity is fixed on the inner wall of the heat exchange shell. The inside of the spiral cavity is hollow. A partition is fixed in the middle of the inner wall of the spiral cavity. During work, the spiral cavity is fixed therein through the heat exchange shell, so that the liquid passing through the heat exchange shell is heat-exchanged, and the liquid heat-exchanged in the heat exchange shell is centralized through the centralized cover.
[0008] Further, the outer ring end of the spiral cavity is open, and the outer ring end of the spiral cavity is fixed on the inner wall of the heat exchange housing. The spiral cavity conveys liquid through the open end.
[0009] Further, an input port is fixedly communicated with the periphery of the heat exchange housing above the partition plate, an output port is fixedly communicated with the periphery of the heat insulation housing below the partition plate, and an emptying pipe is fixedly communicated with the periphery of the heat exchange housing below the output port. The input port, the output port, and the emptying pipe are all corresponding to the position of the outer ring end of the spiral cavity. When the partition plate works, the liquid to be heat-exchanged is conveyed into the spiral cavity through the input port, and is spirally output into the output port and discharged in the spiral cavity.
[0010] Further, the inner ring end of the spiral cavity is closed, the partition plate is also spiral, and evenly vertically penetrating conveying holes are formed in the inner circle of the partition plate. The spiral cavity conducts the reverse flow of the liquid to be heat-exchanged through the conveying holes on the partition plate.
[0011] Further, an output hopper is fixedly communicated with the bottom end of the liquid infusion cavity, an infusion pipe is fixedly communicated with the bottom end of the output hopper, and a support frame is fixed on the periphery of the liquid infusion cavity. When the liquid infusion cavity works, the liquid is conveyed into the output hopper through the infusion pipe, then conveyed into the liquid infusion cavity through the output hopper, and then rises into the heat exchange housing, so that the liquid for heat exchange evenly passes through the liquid infusion cavity.
[0012] Further, a liquid discharge port is fixedly communicated with the top end of the centralized cover, and the inner diameter of the liquid discharge port is equal to the inner diameter of the infusion pipe. The centralized cover discharges the liquid heat-exchanged in the heat exchange housing through the liquid discharge port.
[0013] The utility model has the following beneficial effects:
[0014] By arranging the heat exchange housing, the utility model solves the problems that the flow path of the liquid to be heat-exchanged is limited during the operation of the spiral plate heat exchanger and the heat exchange effect is not good enough. The liquid to be heat-exchanged is conveyed to the upper part of the spiral cavity in the heat exchange housing through the input port, spirally conveyed in the upper part of the spiral cavity, conveyed into the inner circle of the spiral cavity, and then through the conveying holes on the partition plate, so that the liquid to be heat-exchanged entering the upper part of the spiral cavity flows to the lower part thereof and changes the flow direction. Finally, it is discharged through the output port. The liquid passing through the heat exchange housing rises and is conveyed into the centralized cover, so that the liquid passing through the spiral cavity can enter and exit laterally, the pipeline is connected horizontally, and the liquid to be heat-exchanged can pass through the double spiral cavity spiral length, enhancing the heat exchange effect.
[0015] The utility model solves the problems that when a spiral plate heat exchanger works, the liquid is directly transported through a single pipeline, resulting in uneven liquid flow and poor heat exchange effect. The liquid to be transported is transported through a liquid delivery pipe to a discharge hopper, then rises to a liquid infusion cavity through the discharge hopper. The liquid passing through the liquid infusion cavity is homogenized and rises through dispersion holes when passing through a homogenization plate, and then rises and is transported in the liquid infusion cavity to a heat exchange housing. After heat exchange with a spiral cavity in the heat exchange housing, the liquid rises to a central cover, and the central cover discharges the concentrated liquid through a liquid discharge port, making the flow between the liquid to be heat-exchanged and the heat-exchanging liquid more sufficient.

Specific Embodiment 1
[0025] Please refer to Figures 1-5 , the utility model is a side-inlet and side-outlet structure spiral plate heat exchanger, which includes a heat exchange housing 1, a liquid delivery cavity 2 and a centralized cover 3. The centralized cover 3 is fixed at the top end of the heat exchange housing 1. The heat exchange housing 1 fixes the spiral cavity 101 therein. When the liquid that needs heat exchange passes through the spiral cavity 101, the liquid for heat exchange passes through the outer space of the spiral cavity 101 in the heat exchange housing 1 to exchange heat with the liquid passing through the spiral cavity 101. The bottom end of the heat exchange housing 1 is fixedly connected and communicated with the liquid delivery cavity 2. The heat exchange liquid input therein is lifted and conveyed into the heat exchange housing 1 through the liquid delivery cavity 2. A homogenizing plate 201 is fixed on the inner wall of the liquid delivery cavity 2. Uniform dispersion holes 202 are uniformly formed through the homogenizing plate 201. When the heat exchange liquid entering the liquid delivery cavity 2 passes through the homogenizing plate 201, it is homogenized through the dispersion holes 202 and rises into the heat exchange housing 1. A spiral cavity 101 is fixed on the inner wall of the heat exchange housing 1. The inside of the spiral cavity 101 is hollow. A partition plate 102 is fixed in the middle of the inner wall of the spiral cavity 101. During operation, the liquid entering the spiral cavity 101 is conveyed in a reverse direction through the partition plate 102, so that the path of the liquid that needs heat exchange passing through the spiral cavity 101 in the heat exchange housing 1 is increased, and the flow directions of the liquid that needs heat exchange (hot fluid) in the spiral cavity 101 and the liquid for heat exchange (cold fluid) passing through the heat exchange housing 1 are perpendicular to each other.
[0026] Specifically, the outer ring end of the spiral cavity 101 is open, and the outer ring end of the spiral cavity 101 is fixed on the inner wall of the heat exchange housing 1. The spiral cavity 101 is open at the end for conveying the liquid that needs heat exchange.

During operation, the liquid that needs heat exchange is conveyed into the spiral cavity 101 through the input port 104, and the liquid that needs heat exchange is output to the return pipeline through the output port 103.
[0028] Further, the inner ring end of the spiral cavity 101 is closed, and the partition 102 is also spiral. Uniform vertical through holes 1021 are provided in the inner ring of the partition 102. The spiral cavity 101 enables the liquid to be heat-exchanged entering the upper part of the spiral cavity 101 to flow to the lower part thereof through the through holes 1021 in the inner ring of the partition 102 and change the flow direction.
[0029] The operation process of this embodiment is as follows: During operation, the liquid to be heat-exchanged is transported through the input port 104 to the upper part of the spiral cavity 101 in the heat-exchanging housing 1, spirally transported in the upper part of the spiral cavity 101, and transported into the inner ring of the spiral cavity 101. Then, through the through holes 1021 in the partition 102, the liquid to be heat-exchanged entering the upper part of the spiral cavity 101 flows to the lower part thereof and changes the flow direction. Finally, it is discharged through the output port 103.
