Description

Technical Field

[0001] The utility model belongs to the technical field of environmentally friendly heat exchange equipment, and in particular relates to an environmentally friendly heat exchange equipment. Background Art

[0002] Heat exchangers are devices that transfer part of the heat of hot fluid to cold fluid, also known as heat exchangers. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. Among them, fluoroplastic shell and tube heat exchangers are widely used because of their strong corrosion resistance and anti-aging performance, and their excellent temperature resistance, which makes them suitable for both steam heating and hot water heating.

[0003] Common fluoroplastic shell and tube heat exchangers are composed of two major parts: the shell and the inner core. The inner core tube bundle is made of fluoroplastic, and the outer shell is made of metal or steel lined with fluorine, etc. When the fluoroplastic shell and tube heat exchanger is in operation, since the inlet of the hot material is close to the connection between the tube sheet and the tube bundle, when the material is added, the hotter material releases a lot of heat to the connection between the tube sheet and the tube bundle. At the same time, when the condensate enters the shell through the tube bundle, the temperature difference between the temperature in the tube bundle and the temperature on the tube shell increases, resulting in a large temperature difference between the tube sheet and the two sides of the tube bundle. The large temperature difference will cause the tube bundle to expand to different degrees on both sides of the tube sheet. When the same tube bundle expands to different degrees, the connection between the tube sheet and the tube bundle will rupture.

[0004] Most of the fluoroplastic shell and tube heat exchangers in the prior art do not have the function of adjusting the temperature difference between the tube sheet and the tube bundle, resulting in a large temperature difference between the tube sheet and the tube bundle during actual application, which leads to rupture of the connection between the tube sheet and the tube bundle, resulting in leakage of the fluoroplastic shell and tube heat exchanger. When the fluoroplastic shell and tube heat exchanger leaks, the material will mix with the condensate through the tube sheet, making the heat exchanger unable to operate normally.

[0005] Therefore, in view of the above technical problems, it is necessary to provide an environmentally friendly heat exchange equipment.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0007] The utility model aims to provide an environmentally friendly heat exchange equipment, which can reduce the temperature difference between the tube sheet and the tube bundle, and reduce the phenomenon of cracking and leakage between the tube sheet and the tube bundle due to excessive temperature difference.

[0008] In order to achieve the above-mentioned purpose, a specific embodiment of the utility model provides an environmentally friendly heat exchange device, including: a heat exchanger, a temperature difference regulating heat exchange mechanism, and a matching sealing mechanism.

[0009] The heat exchanger consists of an end cover and a tube body. The end cover is connected to the tube body by bolts, and a feed pipe is fixedly connected to the side of the tube body.

[0012] In one or more embodiments of the utility model, the outer side of the end cover is connected to a condenser pipe, and the condenser pipe and the partition plate are arranged on the same side of the heat exchanger. By connecting the condenser pipe with the end cover, it is convenient to add condensate into the heat exchanger through the condenser pipe, so that the condensate cools the material in the heat exchanger.

[0014] In one or more embodiments of the utility model, a side of the tube body away from the feed tube is fixedly connected to a discharge tube. The provision of the discharge tube facilitates the discharge of materials from the tube body.

[0015] In one or more embodiments of the utility model, multiple groups of baffles are fixedly installed on the inner wall of the tube body, and the multiple groups of baffles are staggered in the tube body, and the multiple groups of tube bundles are all penetrated by the baffle arrangement. Through the arrangement of the baffles, it is convenient to fix the multiple groups of tube bundles in the tube body through the baffles, and at the same time, by staggering the multiple groups of baffles, the baffles change the flow direction of the material in the tube body, reduce the flow dead zone of the material, lengthen the flow of the material in the tube body, and improve the heat exchange efficiency.

[0016] In one or more embodiments of the utility model, a guide impeller is rotatably installed on one side of the shunt pipe located in the feed pipe.

Through the setting of the partition plate, it is convenient to separate the inlet of the feed pipe into two inlets through the partition plate, so that it is convenient for the material to enter the tube sheet through the shunt pipe, thereby balancing the temperature difference between the inside and outside of the tube sheet.

[0017] In one or more embodiments of the utility model, an overflow pipe is fixedly connected to one side of the tube sheet located in the tube body.

[0018] In one or more embodiments of the utility model, a plurality of evenly distributed matching frames are fixedly installed on one side of the matching gasket close to the tube bundle. By setting the plurality of matching frames, the matching frames are matched and installed on the side of the matching gasket close to the tube bundle, so that when the matching gasket expands or contracts violently, the matching frames can match the violent expansion of the matching gasket and increase the elasticity of the matching gasket.

[0019] In one or more embodiments of the utility model, multiple groups of the matching frames are filled with foam glue, so that when the matching gasket expands or contracts violently, the matching frame is broken, the foam glue overflows from the matching frame, expands and solidifies, and the tube bundle is sealed and connected in the tube sheet.

[0020] In one or more embodiments of the utility model, a limiting ring is installed on one end of the matching gasket located in the end cover, and the limiting ring is sleeved on one end of the tube bundle located in the end cover.

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0033] like Figures 1 to 7 As shown, an environmentally friendly heat exchange device in one embodiment of the utility model includes: a heat exchanger 1, a temperature difference regulating heat exchange mechanism 2, and a matching sealing mechanism 3.

[0034] like Figure 1 As shown, the heat exchanger 1 consists of an end cover 101 and a tube body 102, and the end cover 101 and the tube body 102 are connected by bolts. The heat exchanger 1 is assembled by bolting the end cover 101 and the tube body 102 together, so that the heat exchanger 1 can withstand the pressure of the material, ensuring the stable operation of the heat exchanger 1.

[0035] like Figure 1 As shown, the side of the tube body 102 is fixedly connected with a feed pipe 103. The feed pipe 103 is arranged to facilitate the material to be heat exchanged to enter the heat exchanger 1 through the feed pipe 103, so that the multiple tube bundles 202 in the heat exchanger 1 are fully in contact with the material, thereby exchanging heat with the material.

[0036] like Figure 1 As shown, the outer side of the end cover 101 is connected to a condenser 104, and the condenser 104 and the partition plate 207 are arranged on the same side of the heat exchanger 1. By connecting the condenser 104 with the end cover 101, it is convenient to pass the condensate into the heat exchanger 1 through the condenser 104, so that the condensate exchanges heat with the material in the heat exchanger 1.

[0037] like Figure 1As shown, a liquid outlet pipe 105 is fixedly connected to one side of the end cover 101 away from the condenser pipe 104. The arrangement of the liquid outlet pipe 105 facilitates the discharge of condensate from the heat exchanger 1 through the liquid outlet pipe 105.

[0038] like Figure 1 As shown, a partition is fixedly connected inside the end cover 101, and the partition divides the end cover 101 into a low-temperature liquid inlet chamber 106 and a high-temperature liquid discharge chamber 107. The condenser 104 is in communication with the low-temperature liquid inlet chamber 106, and the liquid outlet pipe 105 is in communication with the high-temperature liquid discharge chamber 107. The two ends of the multiple tube bundles 202 are respectively in communication with the low-temperature liquid inlet chamber 106 and the high-temperature liquid discharge chamber 107. By dividing the end cover 101 into the low-temperature liquid inlet chamber 106 and the high-temperature liquid discharge chamber 107, it is convenient for the condensate to enter through the low-temperature liquid inlet chamber 106 and then be discharged through the high-temperature liquid discharge chamber 107, thereby increasing the heat exchange effect on the material.

[0039] like Figure 1 As shown, a discharge pipe 108 is fixedly connected to one side of the tube body 102 away from the feed pipe 103. The discharge pipe 108 is located on the side of the tube body 102 away from the feed pipe 103. The arrangement of the discharge pipe 108 facilitates the discharge of the heat-treated material from the tube body 102.

[0040] like Figure 1 to Figure 2 As shown, the temperature difference regulating heat exchange mechanism 2 is fixedly assembled in the heat exchanger 1, and the temperature difference regulating heat exchange mechanism 2 includes a tube sheet 201, and the tube sheet 201 is fixedly assembled in the heat exchanger 1, and the tube sheet 201 is a cavity. Through the arrangement of the tube sheet 201, the tube bundle 202 is installed and arranged through the tube sheet 201, and the fluids in the end cover 101 and the tube body 102 are separated by the tube sheet 201 to avoid mixing of cold and hot fluids, and at the same time bear the pressure on both sides of the end cover 101 and the tube body 102.

[0041] like Figure 1 to Figure 2 As shown, multiple groups of tube bundles 202 are fixedly connected in the tube sheet 201, and the openings of the multiple groups of tube bundles 202 are arranged toward the end cover 101. By matching and connecting the multiple groups of tube bundles 202 with the tube sheet 201, the condensate is passed into the multiple groups of tube bundles 202, so that the multiple groups of tube bundles 202 perform heat exchange with the material in the tube body 102, thereby achieving the purpose of cold and heat exchange.

[0042] like Figure 1 to Figure 2 As shown, the side of the tube sheet 201 is connected with a shunt pipe 203, which penetrates the tube sheet 201, and one end of the shunt pipe 203 located in the tube body 102 is connected with the feed pipe 103. Through the arrangement of the shunt pipe 203, the shunt pipe 203 allows the material in the feed pipe 103 to be passed into the cavity in the tube sheet 201, thereby reducing the internal and external temperature difference between the tube sheet 201 and the tube bundle 202, and reducing the situation where the mating gasket 301 is severely deformed due to excessive temperature difference.

[0043] like Figure 1 to Figure 2 As shown, one end of the shunt pipe 203 located in the end cover 101 is fixedly connected to an elbow 204, and the end of the elbow 204 away from the shunt pipe 203 is connected to the cavity of the tube sheet 201. Through the setting of the elbow 204, the material in the shunt pipe 203 enters the tube sheet 201 through the elbow 204, thereby reducing the temperature difference between the inside and outside of the tube sheet 201.

[0044] Specifically, the material in the diverter pipe 203 enters the elbow 204, and the elbow 204 cooperates with the condenser 104, so that the condensate entering through the condenser 104 pre-cools the material in the elbow 204, and then the pre-cooled material is passed into the tube sheet 201 to fill the entire tube sheet 201, so that when the condensate passes through the tube sheet 201 and enters the multiple tube bundles 202, the temperature difference between the inside and outside of the tube bundle 202 is reduced.

[0045] like Figure 1 to Figure 2 As shown, multiple groups of baffles 205 are fixedly installed on the inner wall of the tube body 102, and the multiple groups of baffles 205 are staggered in the tube body 102, and the multiple groups of tube bundles 202 are all arranged through the baffles 205. Through the arrangement of the baffles 205, it is convenient to fix the multiple groups of tube bundles 202 in the tube body 102 through the baffles 205, and at the same time, by staggering the multiple groups of baffles 205, the baffles 205 change the flow direction of the material in the tube body 102, reduce the flow dead zone of the material, lengthen the flow process of the material in the tube body 102, and improve the heat exchange efficiency.

[0046] like Figures 1 to 3 As shown, a guide impeller 206 is rotatably mounted on one side of the shunt pipe 203 located in the feed pipe 103. By setting the guide impeller 206, when material is introduced into the pipe body 102 through the feed pipe 103, the material drives the guide impeller 206 to rotate, thereby accelerating the speed at which the material enters the shunt pipe 203.

[0047] like Figures 1 to 3 As shown, a partition plate 207 is fixedly installed in the feed pipe 103, and the partition plate 207 divides the feed pipe 103 into a temperature adjustment feed port and a heat exchange feed port, and the feed pipe 103 is connected to the temperature adjustment feed port. Through the arrangement of the partition plate 207, it is convenient to divide the inlet of the feed pipe 103 into two inlets through the partition plate 207, so that the material can enter the tube sheet 201 through the diverter pipe 203, so as to balance the temperature difference between the inside and outside of the tube sheet 201.

[0048] like Figure 6As shown, an overflow pipe 208 is fixedly connected to one side of the tube sheet 201 located in the tube body 102. The overflow pipe 208 is provided to facilitate the discharge of the material entering the tube sheet 201 through the elbow 204 through the overflow pipe 208. At the same time, the overflow pipe 208 is connected with the diverter pipe 203, so that the material entering through the elbow 204 can balance the temperature of the tube sheet 201 without dead angles, thereby reducing the temperature difference between the inside and outside of the tube sheet 201.

[0049] like Figures 1 to 7 As shown, multiple sets of matching sealing mechanisms 3 are fixedly assembled in the tube sheet 201, and the matching sealing mechanisms 3 include matching gaskets 301, which are matched and installed between the tube sheet 201 and the tube bundle 202. Through the arrangement of the matching gaskets 301, it is convenient to match and install the tube bundle 202 in the tube sheet 201 through the matching gaskets 301, so that the tube sheet 201 and the tube bundle 202 are sealed and connected.

[0050] like Figure 2 As shown, a sealing box 302 is installed on the outer side of the mating gasket 301. By fitting the sealing box 302 on the outer side of the mating gasket 301, when the mating gasket 301 expands violently, the sealing box 302 cooperates with the mating gasket 301 to seal the tube bundle 202, so that the tube bundle 202 is sealed and connected to the tube sheet 201.

[0051] like Figures 1 to 7 As shown, the sealing box 302 is fixedly installed in the tube sheet 201, and the sealing box 302 is filled with an expansion agent 303. Therefore, when the matching gasket 301 expands or contracts violently, the matching gasket 301 punctures the sealing box 302, and the expansion agent 303 in the sealing box 302 overflows and expands and solidifies, so that the tube bundle 202 is sealed and connected in the tube sheet 201.

[0052] Preferably, the expansion agent 303 may be a polyurethane foaming agent, which has the advantages of being not easy to age, having good foam strength, and having good adhesion.

[0053] like Figures 2 to 4 As shown, a plurality of evenly distributed matching frames 304 are fixedly installed on one side of the matching gasket 301 close to the tube bundle 202. By setting the plurality of matching frames 304, the matching frames 304 are matched and installed on the side of the matching gasket 301 close to the tube bundle 202, so that when the matching gasket 301 expands or contracts sharply, the matching frames 304 can match the sharp expansion of the matching gasket 301, and at the same time, the elasticity of the matching gasket 301 can be increased.

[0054] like Figures 2 to 4As shown, multiple groups of matching frames 304 are filled with foam glue 305. Therefore, when the matching gasket 301 expands or contracts violently, the matching frame 304 is broken, and the foam glue 305 overflows from the matching frame 304 and expands and solidifies, so that the tube bundle 202 is sealed and connected in the tube sheet 201.

[0055] Preferably, the matching frame 304 may be made of polyethylene foam, which has the advantages of fast foaming, high expansion, and small shrinkage.

[0056] like Figure 3 to Figure 4 As shown, a limiting ring 306 is installed on one end of the matching gasket 301 located in the end cover 101, and the limiting ring 306 is sleeved on one end of the tube bundle 202 located in the end cover 101. By setting the limiting ring 306, the limiting ring 306 is sleeved on the end of the tube bundle 202 in cooperation with the matching gasket 301, so that the tube bundle 202 and the end of the tube sheet 201 are sealed.

[0057] During specific use, when heat exchange treatment is performed through the heat exchanger 1, the condensate continuously passes through the condenser tube 104 into the low-temperature liquid inlet chamber 106, the condensate flows along the tube sheet 201 into the multiple tube bundles 202, and enters the high-temperature liquid discharge chamber 107 through the outlets of the multiple tube bundles 202, and then is discharged through the liquid outlet pipe 105.

[0058] At the same time, heat exchange material is introduced into the heat exchanger 1 through the feed pipe 103, and the hot material is diverted through the partition plate 207, and enters the tube body 102 and the diverter pipe 203 through the heat exchange feed port and the temperature regulating feed port respectively. The hot material entering the diverter pipe 203 through the temperature regulating feed port drives the guide impeller 206 at the end of the diverter pipe 203 to rotate, and the guide impeller 206 accelerates the speed at which the hot material enters the diverter pipe 203.

[0059] Then the hot material enters the elbow 204 through the shunt pipe 203, and the hot material entering the elbow 204 exchanges heat with the condensate in the low-temperature liquid inlet cavity 106. The condensate pre-cools the hot material in the elbow 204, and the pre-cooled hot material is passed into the cavity in the tube sheet 201, and the hot material fills the entire cavity in the tube sheet 201, so that when the condensate enters the multiple groups of tube bundles 202 through the low-temperature liquid inlet cavity 106, the temperature difference between the pre-cooled hot material in the cavity of the tube sheet 201 and the condensate in the tube bundle 202 is small, so that the temperature difference on both sides of the gasket between the tube bundle 202 and the tube sheet 201 is small, so that the gasket can be used normally.

[0060] The preheated material is then discharged into the tube body 102 through the overflow pipe 208 , the material discharged into the tube body 102 through the overflow pipe 208 is mixed with the material entering through the heat exchange feed port, and exchanges heat with the tube bundle 202 in the tube body 102 , and finally discharged from the heat exchanger 1 through the discharge pipe 108 .

[0061] When the temperature difference between the tube bundle 202 and the tube sheet 201 is too large, the mating gasket 301 expands and deforms, so that the protrusion of the mating gasket 301 close to the tube sheet 201 will pierce the sealing box 302, causing the expansion agent 303 in the sealing box 302 to overflow, and quickly expand and solidify, thereby sealing the gap between the tube bundle 202 and the mating gasket 301. At the same time, when the mating gasket 301 expands and ruptures violently, the multiple groups of mating frames 304 on the side of the mating gasket 301 close to the tube sheet 201 are broken, and the foam glue 305 in the mating frame 304 overflows, and the foam glue 305 quickly expands and solidifies, so that the gap between the tube bundle 202 and the tube sheet 201 is quickly sealed and connected, thereby reducing the leakage of materials into the end cover 101.

[0062] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
