Description

Technical Field

[0001] The utility model relates to the technical field of supporting equipment for coal-bed methane purification, in particular to a double-circulation cooling and heat dissipation device for coal-bed methane purification. Background Art

[0002] Radiators or heat exchangers can cool the incoming heat medium by filling it with cooling medium and are widely used in various fields. In the field of slurry-based coalbed methane purification, methane needs to be cooled after purification. Since most radiators at this stage use the top-in and bottom-out or left-near-right-out method to achieve the flow of heat medium and coolant, the heat dissipation capacity is limited. In order to ensure the cooling effect of the heat medium, a circulation method is required, that is, cooling is achieved by circulating the heat medium into the radiator multiple times.

[0003] However, this method has low operating efficiency, and since the flow path of the coolant in the radiator is short, the coolant flows out of the radiator before being saturated, resulting in a waste of resources.

[0004] Therefore, there is an urgent need to provide a dual-circulation cooling and heat dissipation device for coalbed methane purification to solve the problems existing in the prior art to a certain extent. Utility Model Content

[0005] The utility model aims to provide a dual-circulation cooling and heat dissipation device for coal-bed methane purification, so as to optimize the structure of the dual-circulation cooling and heat dissipation device for coal-bed methane purification to a certain extent and improve the heat dissipation efficiency.

[0006] The utility model provides a dual-circulation cooling and heat dissipation device for coalbed methane purification, comprising a heat dissipation body, a heat dissipation pipe and a partition; the heat dissipation pipe and the partition are both located in the heat dissipation body, and the partition divides the heat dissipation body into a first chamber and a second chamber connected at the bottom; a first inlet, a first outlet, a second inlet and a second outlet are formed on the heat dissipation body, and a connecting cavity is provided at the bottom of the heat dissipation body, one end of the heat dissipation pipe located in the first chamber is connected to the first inlet, and the other end is connected to the connecting cavity, one end of the heat dissipation pipe located in the second chamber is connected to the connecting cavity, and the other end is connected to the first outlet; the second inlet is used to inject coolant into the first chamber or the second chamber, and the coolant enters the first chamber or the second chamber from the bottom of the heat dissipation body and flows out from the second outlet.

[0007] In which, a distribution cavity is provided on the top of the heat dissipation body, and the distribution cavity and the connecting cavity are arranged at two ends of the heat dissipation body opposite to each other, and the partition is located in the distribution cavity and the heat dissipation body, and divides the distribution cavity into a first cavity and a second cavity that are not connected to each other; the first inlet is connected to the first cavity, the first outlet is connected to the second cavity, and the end of the heat dissipation pipe away from the connecting cavity is connected to the first cavity or the second cavity.

[0008] Specifically, the second inlet is arranged corresponding to the second chamber and is communicated with the second chamber, and the second outlet is arranged corresponding to the first chamber and is communicated with the first chamber.

[0009] Further, a level of the second inlet is higher than a level of the second outlet.

[0010] Furthermore, the outer wall surface of the heat dissipation pipe is distributed with a plurality of heat dissipation fins, the plurality of heat dissipation fins are arranged at intervals along the extension direction of the heat dissipation pipe, and the heat dissipation fins of adjacent heat dissipation pipes are arranged in a staggered manner.

[0011] Among them, the dual-circulation cooling and heat dissipation device for coalbed methane purification provided by the utility model also includes a first positioning plate, a first positioning portion is formed on the first positioning plate, and one end of the heat dissipation pipe is inserted into the first positioning portion and connected to the first positioning plate.

[0012] Specifically, the dual-circulation cooling and heat dissipation device for coalbed methane purification provided by the utility model also includes a second positioning plate, which is arranged at both ends of the heat dissipation body opposite to the first positioning plate, and the second positioning plate is formed with a second positioning portion at a position corresponding to the first positioning portion, and the end of the heat dissipation pipe away from the first positioning plate is inserted into the second positioning portion.

[0013] Furthermore, a sealing member is provided inside each of the first positioning portion and the second positioning portion, for sealing the heat dissipation pipe with the first positioning portion and the second positioning portion.

[0014] Among them, the dual-circulation cooling and heat dissipation device for coalbed methane purification provided by the utility model also includes a wire plug, which is arranged at the bottom of the heat dissipation body and is used to close the connecting cavity and remove dust and rust during maintenance.

[0015] Specifically, the dual-circulation cooling and heat dissipation device for coalbed methane purification provided by the utility model also includes a cleaning component, which includes a connecting part and a cleaning part. The connecting part is connected to the heat dissipation body, and the cleaning part is detachably connected to the connecting part. The diameter of the cleaning part is adapted to the inner diameter of the heat dissipation pipe, and is used to clean the heat dissipation pipe.

[0016] Compared with the prior art, the dual-circulation cooling and heat dissipation device for coalbed methane purification provided by the utility model has the following advantages:

[0017] The utility model provides a dual-circulation cooling and heat dissipation device for coalbed methane purification, comprising a heat dissipation body, a heat dissipation pipe and a partition; the heat dissipation pipe and the partition are both located in the heat dissipation body, and the partition divides the heat dissipation body into a first chamber and a second chamber connected at the bottom; a first inlet, a first outlet, a second inlet and a second outlet are formed on the heat dissipation body, a connecting cavity is provided at the bottom of the heat dissipation body, one end of the heat dissipation pipe located in the first chamber is connected to the first inlet, and the other end is connected to the connecting cavity, one end of the heat dissipation pipe located in the second chamber is connected to the connecting cavity, and the other end is connected to the first outlet; the second inlet is used to inject cooling liquid into the first chamber or the second chamber, and the cooling liquid enters the first chamber or the second chamber from the bottom of the heat dissipation body and flows out from the second outlet.

[0018] From this analysis, it can be seen that the heat dissipation body can provide installation space for the heat dissipation pipe and the partition, and by arranging the heat dissipation pipe and the partition in the heat dissipation body, the stability of the arrangement of the two can be ensured. Since the partition in the present application divides the heat dissipation body into two bottom-connected first and second chambers in the heat dissipation body, a first inlet and a first outlet are formed on the heat dissipation body, and the two ends of the heat dissipation pipe in the first chamber are respectively connected to the first inlet and the connecting chamber, and the two ends of the heat dissipation pipe in the second chamber are respectively connected to the first outlet and the connecting chamber, therefore, the heat medium can enter the heat dissipation pipe in the first chamber from the first inlet, and flow along the heat dissipation pipe to the connecting chamber, and as the heat medium in the connecting chamber continues to enter, the heat medium gradually fills up the connecting chamber, so that it can further enter the heat dissipation pipe in the second chamber, and finally flow out from the first outlet.

[0019] It can be understood that since the heat dissipation pipe in the present application extends in the vertical direction, the heat medium can form a U-shaped flow trajectory in the process of entering the heat dissipation pipe in the first chamber from the first inlet to flowing to the connecting chamber, and entering the heat dissipation pipe in the second chamber from the connecting chamber and finally flowing out from the first outlet, which greatly increases the movement distance and retention time of the heat medium in the heat dissipation body, thereby improving the heat dissipation quality.

[0020] Correspondingly, since a second inlet and a second outlet are also formed on the heat dissipation body in the present application, and coolant can be injected into the first chamber or the second chamber through the second inlet, and the coolant can flow out through the second outlet, and the partition in the present application connects the first chamber and the second chamber at the bottom, therefore, taking the second inlet to allow the coolant to enter the first chamber as an example, after the coolant enters the first chamber, it can first flow into the second chamber from the bottom connecting the first chamber and the second chamber, and as the coolant continues to enter, the liquid level in the second chamber gradually rises, thereby realizing heat exchange with the heat dissipation pipe in the second chamber.

[0021] After reaching a certain height, under the action of pressure, the coolant no longer enters the second chamber, but gradually rises in the first chamber and remains consistent with the coolant level in the second chamber, thereby cooling the heat medium in the heat dissipation pipe in the first chamber.

[0022] Correspondingly, as the coolant is continuously charged, the liquid level gradually rises until it reaches the second outlet, and the coolant flows out. However, a certain coolant height is maintained in the first chamber and the second chamber, so that cooling with the heat medium can always be achieved.

[0023] It is understandable that after the coolant flows out from the second outlet, the supply of coolant can be stopped, and the second inlet and the second outlet can be blocked, so that the coolant stays in the heat dissipation body for a certain period of time, thereby reaching a saturated state of the coolant and reducing resource waste to a certain extent.

[0036] like Figure 1As shown, the utility model provides a dual-circulation cooling and heat dissipation device for coalbed methane purification, comprising a heat dissipation body 1, a heat dissipation pipe 2 and a separator 3; the heat dissipation pipe 2 and the separator 3 are both located in the heat dissipation body 1, and the separator 3 divides the heat dissipation body 1 into a first chamber 101 and a second chamber 102 which are connected at the bottom; a first inlet 103, a first outlet 104, a second inlet 105 and a second outlet 106 are formed on the heat dissipation body 1, and a connecting cavity 5 is provided at the bottom of the heat dissipation body 1, one end of the heat dissipation pipe 2 located in the first chamber 101 is connected to the first inlet 103, and the other end is connected to the connecting cavity 5, and one end of the heat dissipation pipe 2 located in the second chamber 102 is connected to the connecting cavity 5, and the other end is connected to the first outlet 104; the second inlet 105 is used to inject coolant into the first chamber 101 or the second chamber 102, and the coolant enters the first chamber 101 or the second chamber 102 from the bottom of the heat dissipation body 1 and flows out from the second outlet 106.

[0037] Compared with the prior art, the dual-circulation cooling and heat dissipation device for coalbed methane purification provided by the utility model has the following advantages:

[0038] The dual-circulation cooling and heat dissipation device for coalbed methane purification provided by the utility model can provide installation space for the heat dissipation pipe 2 and the partition 3 through the heat dissipation main body 1, and by arranging the heat dissipation pipe 2 and the partition 3 in the heat dissipation main body 1, the stability of the arrangement of the two can be ensured. Since the partition 3 in the present application divides the heat dissipation body 1 into two bottom-connected first chambers 101 and second chambers 102 in the heat dissipation body 1, a first inlet 103 and a first outlet 104 are formed on the heat dissipation body 1, and the two ends of the heat dissipation pipe 2 located in the first chamber 101 are respectively connected to the first inlet 103 and the connecting chamber 5, and the two ends of the heat dissipation pipe 2 in the second chamber 102 are respectively connected to the first outlet 104 and the connecting chamber 5. Therefore, the heat medium can enter the heat dissipation pipe 2 located in the first chamber 101 from the first inlet 103, and flow along the heat dissipation pipe 2 to the connecting chamber 5. As the heat medium in the connecting chamber 5 continues to enter, the heat medium gradually fills up the connecting chamber 5, so that it can further enter the heat dissipation pipe 2 located in the second chamber 102, and finally flow out from the first outlet 104.

[0039] It can be understood that since the heat dissipation pipe 2 in the present application extends in the vertical direction, the heat medium can form a U-shaped flow trajectory in the process of entering the heat dissipation pipe 2 in the first chamber 101 from the first inlet 103 to flowing to the connecting chamber 5, and entering the heat dissipation pipe 2 in the second chamber 102 from the connecting chamber 5 and finally flowing out from the first outlet 104, which greatly increases the movement distance and retention time of the heat medium in the heat dissipation body 1, thereby improving the heat dissipation quality.

[0040] Correspondingly, since a second inlet 105 and a second outlet 106 are also formed on the heat dissipation body 1 in the present application, and coolant can be injected into the first chamber 101 or the second chamber 102 through the second inlet 105, and the second outlet 106 can allow the coolant to flow out, and the partition in the present application connects the first chamber 101 and the second chamber 102 at the bottom, therefore, taking the second inlet 105 to allow the coolant to enter the first chamber 101 as an example, when the coolant enters the first chamber 101, it can first flow into the second chamber 102 from the bottom connecting the first chamber 101 and the second chamber 102, and as the coolant continues to enter, the liquid level in the second chamber 102 gradually rises, thereby achieving heat exchange with the heat dissipation pipe 2 in the second chamber 102.

[0041] After reaching a certain height, under the action of pressure, the coolant no longer enters the second chamber 102, but gradually rises in the first chamber 101 and remains consistent with the liquid level of the coolant in the second chamber 102, thereby achieving cooling of the heat medium in the heat dissipation pipe 2 in the first chamber 101.

[0042] Accordingly, as the coolant is continuously charged, the liquid level gradually rises until it reaches the second outlet 106, and the coolant flows out. However, a certain coolant height is maintained in the first chamber 101 and the second chamber 102, so that cooling with the heat medium can always be achieved.

[0043] It is understandable that after the coolant flows out from the second outlet 106, the supply of the coolant can be stopped, and the second inlet 105 and the second outlet 106 can be blocked, so that the coolant stays in the heat dissipation body 1 for a certain period of time, thereby reaching a saturated state of the coolant and reducing the waste of resources to a certain extent.

[0044] It should be noted that the connection between the heat dissipation pipe 2 and the first inlet 103 in the present application can be achieved by a connecting pipe or the like, but preferably, Figure 1 As shown, a distribution cavity 4 is provided on the top of the heat dissipation body 1 in the present application, and the distribution cavity 4 and the connecting cavity 5 are arranged at the two ends of the heat dissipation body 1 opposite to each other, and the partition 3 is located in the distribution cavity 4 and the heat dissipation body 1, and divides the distribution cavity 4 into a first cavity 401 and a second cavity 402 that are not connected to each other; the first inlet 103 is connected to the first cavity 401, the first outlet 104 is connected to the second cavity 402, and the end of the heat dissipation pipe 2 away from the connecting cavity 5 is connected to the first cavity 401 or the second cavity 402.

[0045] The distribution chamber 4 in the present application is located at the top of the heat dissipation body 1, and can form two mutually unconnected first cavities 401 and second cavities 402 through the partition 3, so that by connecting the heat dissipation pipe 2 in the first chamber 101 with the first cavity 401, the heat medium can enter, and correspondingly, by connecting the heat dissipation pipe 2 in the second chamber 102 with the second cavity 402, the heat medium can flow out, thereby completing the flow of the heat medium in the heat dissipation body 1.

[0046] More preferably, if Figure 1 As shown, the second inlet 105 in the present application is arranged corresponding to the second chamber 102 and is communicated with the second chamber 102 , and the second outlet 106 is arranged corresponding to the first chamber 101 and is communicated with the first chamber 101 .

[0047] By setting the second inlet 105 corresponding to the second chamber 102 and the second outlet 106 corresponding to the first chamber 101, when the coolant is supplied, the coolant can first enter the first chamber 101, and after the liquid level is higher than the lowest position of the partition 3, the coolant in the first chamber 101 and the coolant in the second chamber 102 can rise synchronously, thereby realizing the function of cooling the heat medium in the heat dissipation pipe 2.

[0048] It is understandable that if Figure 1 As shown, the horizontal height of the second inlet 105 in the present application is higher than the horizontal height of the second outlet 106, and the second outlet 106 is arranged close to the top of the heat dissipation body 1, so that the liquid level of the coolant filled in the heat dissipation body 1 can be as high as possible, thereby ensuring that most of the area of ​​the heat dissipation pipe 2 can be immersed in the coolant, thereby achieving a better cooling effect.

[0049] Alternatively, if Figure 1 As shown, the outer wall surface of the heat dissipation pipe 2 in the present application is distributed with a plurality of heat dissipation fins 201 , the plurality of heat dissipation fins 201 are arranged at intervals along the extension direction of the heat dissipation pipe 2 , and the heat dissipation fins 201 of adjacent heat dissipation pipes 2 are arranged in a staggered manner.

[0050] The contact area between the heat dissipation pipe 2 and the coolant can be increased by setting a plurality of heat dissipation fins 201 on the outer wall of the heat dissipation pipe 2, thereby improving the cooling effect. In addition, since the heat dissipation fins 201 of adjacent heat dissipation pipes 2 in the present application are staggered, when the coolant flows in the first chamber 101 and the second chamber 102, the heat dissipation fins 201 can play a role in blocking the coolant to a certain extent, so that the coolant flows slowly and improves the heat exchange efficiency.

[0051] It is understandable that if Figure 1As shown, the dual-circulation cooling and heat dissipation device for coalbed methane purification provided by the utility model also includes a first positioning plate 6, on which a first positioning portion is formed, and one end of the heat dissipation pipe 2 is inserted into the first positioning portion and connected to the first positioning plate 6.

[0052] The first positioning plate 6 can realize stable positioning of the heat dissipation pipe 2, thereby preventing the heat dissipation pipe 2 from deviating or tilting in the heat dissipation body 1, and ensuring stable input and outflow of the heat medium.

[0053] It should be noted that the dual-circulation cooling and heat dissipation device for coalbed methane purification in the present application also includes an upper flange 12 located at the top of the heat dissipation body 1 and a sealing gasket 11 corresponding to the upper flange 12. The upper flange 12 can be used to seal the top of the heat dissipation body 1, and as Figure 1 As shown, since the upper flange 12 in the present application is detachably connected to the heat dissipation body 1 , when maintenance or cleaning is required, the upper flange 12 can be removed, thereby enabling cleaning of the interior of the heat dissipation body 1 .

[0054] Accordingly, if Figure 1 As shown, the dual-circulation cooling and heat dissipation device for coalbed methane purification provided by the utility model also includes a second positioning plate 7, which is arranged at both ends of the heat dissipation body 1 relative to the first positioning plate 6, and the second positioning plate 7 is formed with a second positioning portion at a position corresponding to the first positioning portion, and the end of the heat dissipation pipe 2 away from the first positioning plate 6 is inserted into the second positioning portion.

[0055] The second positioning plate 7 can cooperate with the first positioning plate 6 to realize the positioning of the heat dissipation pipe 2 , thereby ensuring that the heat dissipation pipe 2 can always extend in the vertical direction in the heat dissipation body 1 .

[0056] It is necessary to further explain here that the dual-circulation cooling and heat dissipation device for coalbed methane purification in the present application also includes a lower flange 13 located at the bottom of the heat dissipation body 1 and a sealing gasket 11 corresponding to the lower flange 13, and the bottom of the heat dissipation body 1 can be sealed by the lower flange 13, and, as Figure 1 As shown, since the lower flange 13 in the present application is detachably connected to the heat dissipation body 1, when maintenance or cleaning is required, the lower flange 13 can also be removed to achieve cleaning of the inside of the heat dissipation body 1 or directly lift the heat dissipation pipe 2 out for maintenance.

[0057] It is understandable that if Figure 1 As shown, the first positioning portion and the second positioning portion in the present application are both provided with sealing members 8 for sealing the heat dissipation pipe 2 and the first positioning portion and the second positioning portion.

[0058] Alternatively, if Figure 1As shown, the dual-circulation cooling and heat dissipation device for coalbed methane purification provided by the utility model also includes a wire plug 16, which is arranged at the bottom of the heat dissipation body 1 and is used to close the connecting cavity 5.

[0059] The connecting cavity 5 is closed by the thread plug 16 . When the connecting cavity 5 needs to be cleaned, the thread plug 16 can be directly removed, which greatly improves the cleaning efficiency.

[0060] Alternatively, if Figure 1 As shown, the dual-circulation cooling and heat dissipation device for coalbed methane purification provided by the utility model also includes a cleaning component, which includes a connecting piece 9 and a cleaning piece 10. The connecting piece 9 is connected to the heat dissipation body 1, and the cleaning piece 10 is detachably connected to the connecting piece 9. The diameter of the cleaning piece 10 is adapted to the inner diameter of the heat dissipation pipe 2, and is used to clean the heat dissipation pipe 2.

[0061] The connecting piece 9 in the present application can be a turning leaf, through which a limiting space can be formed with the outer wall of the heat dissipation body 1, so that the cleaning piece 10 can be attached to the outer wall of the heat dissipation body 1. When the heat dissipation pipe 2 needs to be cleaned, the upper flange 12 is opened, the connecting piece 9 is operated, the limiting space is opened, and the cleaning piece 10 is removed, so that the cleaning operation of the heat dissipation pipe 2 can be realized.

[0062] Correspondingly, the cleaning member 10 in the present application is a drill rod.

[0063] It should be noted here that in the present application, the bottom of the heat dissipation body 1 is also connected to a drain valve 15 which is connected to the connecting cavity 5 and is used to discharge the residual coolant, and the bottom of the heat dissipation body 1 is also provided with a plurality of legs 14, which can support the heat dissipation body 1 off the ground, thereby ensuring the stable drainage of the drain valve 15 and the disassembly and assembly of the lower flange 13.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
