[0002] With the continuous advancement of industrial technology, more and more heat exchange equipment is widely used in various fields. Heat exchange equipment is a device that transfers heat from hot fluid to cold fluid, also known as a heat exchanger. It transfers heat from one fluid to another through a specific heat transfer method, thereby realizing the transfer and utilization of heat.

The electrically controlled valves 1, 2 and 3 are all connected to the heat exchange system signal.

[0006] According to the above technical solution, the liquid inlet 1 is located on the outer side of the shell compared to the liquid inlet 2, and the three-way pipe is located on the outer side of the shell compared to the liquid outlet 2, and temperature sensors are installed in the liquid outlet 1 and the liquid outlet 2, and the temperature sensors in the liquid outlet 1 and the liquid outlet 2 are both connected to the heat exchange system signal.

[0007] According to the above technical solution, the support mechanism includes a support, which is a structure with a hollow "U"-shaped body on the top and four support columns fixed on the bottom, and the hollow "U"-shaped body of the support is adapted to the outer contour of the shell.

[0008] According to the above technical solution, a shock-absorbing spring is arranged around the support column of the support, and a fixing plate is welded to the bottom of the support column of the support.

[0009] According to the above technical solution, a rotating motor is installed on the inner wall of the hollow "U"-shaped body of the support, and the rotating motor is connected to the heat exchange system signal, a gear is connected to the upper shaft of the rotating motor, an insulation plate is installed in the hollow "U"-shaped body of the support, and a plurality of tooth grooves are evenly installed on the inner walls at both ends of the insulation plate, and a gear is installed in the tooth groove on the side where the rotating motor is not installed, and the gear is movably connected to the inner wall of the hollow "U"-shaped body of the support through a connecting rod, and the two gears are relative to the support, and the tooth grooves are meshed with the gears.

[0010] According to the above technical solution, a connecting rod is riveted on the reciprocating mechanism, a positioning plate is welded on the end of the connecting rod, and a plurality of brushes are fixed on the positioning plate.

[0011] According to the above technical solution, the reciprocating mechanism includes a positioning frame, which is a rectangular frame structure.

A ratchet is connected to the upper shaft of the drive motor, and the ratchet is meshingly connected to the tooth column.

[0012] According to the above technical solution, the side of the positioning frame body opposite to the telescopic rod is welded to the connecting rod.

[0013] According to the above technical solution, the operation steps of the efficient heat exchange equipment include: The required temperature of the liquid after heat exchange is set to T, which is set by the heat exchange system. The actual temperature of the liquid after heat exchange is t1, which is fed back by the temperature sensor in the second liquid outlet. The temperature fed back by the temperature sensor in the first liquid outlet is t2. Under normal circumstances, when t1 is less than T, the temperature t2 of the medium liquid after heat exchange is detected by the temperature sensor in the first liquid outlet. The heat exchange efficiency v is calculated by comparing t2 with the initial temperature of the medium liquid. The heat exchange efficiency of the medium liquid under normal circumstances is set to V. When v is less than V, it means that the heat exchange efficiency is too low. The heat exchange system will stop the liquid inlet of liquid inlet 1 and liquid inlet 2, close the electric control valve 3, open the electric control valve 2 and the electric control valve 1, so that the flushing liquid is pumped to the backwashing pipe and then enters the shell, and flows through the pipe, so that the dirt on the inner wall of the pipe flows to the heat exchange liquid inlet end of the pipe under the impact of the flushing liquid, and then discharged into the waste water tank through the sewage pipe. The dirt that has not been flushed out of the pipe port is brushed by the brush driven by the reciprocating mechanism, so that it is brushed out after repeated brushing and enters the waste water tank together; In a low temperature environment, in order to save energy, if the temperature t1 of the heat exchange liquid rises slowly after the shell is insulated by the insulation board, the reciprocating mechanism and the brush can be started to circulate and scrub the tubes in the shell before the medium liquid is increased. At the same time, the flushing liquid is heated and pumped to the backwash pipe after being passed into the pipe, which can better break down the dirt. At the same time, the heat of the backwashing liquid will be transferred to the inner wall of the pipe, thereby achieving a preheating effect, so that when the heat exchanger is used again, the heat exchanger will reach the normal operating temperature faster, thereby improving the heat exchange efficiency.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: (1) The support mechanism provides insulation measures, so that the equipment can maintain the original heat exchange efficiency in a low temperature environment. Compared with the method of directly increasing the medium liquid, the insulation board can reduce the heat loss to the surrounding environment, saving more energy. The support mechanism as a whole has a strong shock-absorbing effect, which helps to prevent the vibration of the pipe caused by external force or medium flow, thereby protecting the integrity of the pipe and the heat exchange equipment as a whole; (2) A reciprocating mechanism is provided to drive the brush to scrub back and forth, and the backwash pipe is used to realize real-time flushing of the internal pipes, thereby avoiding scaling inside the pipes and reducing the heat exchange efficiency. The operation of heating the flushing liquid can also have a certain preheating effect on the pipes, so that the efficiency of the heat exchange equipment remains stable in a low-temperature environment. Compared with the direct driving method through a motor, the reciprocating mechanism has higher high-temperature resistance and can maintain a stable working state at such a high temperature of the heat exchange equipment.

DETAILED DESCRIPTION

[0016] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] The embodiment of the present invention provides a highly efficient heat exchange device. Figure 1 FIG. 1 is a schematic diagram of a structure of an efficient heat exchange device according to an embodiment of the present invention, Figure 1-2As shown, the efficient heat exchange equipment includes a shell 1, and a liquid inlet 2 is installed on the upper side of one side of the shell 1 for introducing a medium fluid. A liquid inlet 2 3 is installed on the upper side of one side of the shell 1, which is parallel to the liquid inlet 2, for introducing a heat exchange fluid, and a liquid discharge pipe 11 is installed on the shell 1 just below the liquid inlet 2. A three-way pipe 4 is installed below the other side of the shell 1, and the two output pipes of the three-way pipe 4 are a liquid outlet 41 and a backwash pipe 42, respectively. The liquid outlet 41 is used to release the medium fluid, and the backwash pipe 42 is connected to a cleaning pump for pumping the backwash liquid stored in the water tank. A liquid outlet 2 5 is installed on the lower side of the other side of the shell 1, which is parallel to the three-way pipe 4, for releasing the liquid to be heat exchanged.

[0018] A support mechanism 6 is installed below the shell 1. A support rod 7 is riveted to one side of the support mechanism 6. A reciprocating mechanism 8 is installed inside the support rod 7. A waste water tank 13 is arranged below the support rod 7. The waste water tank 13 is connected to the drain pipe 11. Two separation plates 14 are installed inside the shell 1. The separation plates 14 are circular plate structures with a plurality of holes. A plurality of pipes 15 are evenly installed between the two separation plates 14 through the holes. A guide plate 16 is sleeved on the pipes 15. Figure 7 As shown, the drain pipe 11 is provided with an electric control valve 17, the recoil pipe 42 is provided with an electric control valve 2 18, and the outlet port 1 41 is provided with an electric control valve 3 19. The electric control valve 17, the electric control valve 2 18, and the electric control valve 3 19 are all connected to the heat exchange system signal.

[0019] During the heat exchange process, the electric control valve 17 and the electric control valve 2 18 are in a closed state, and the electric control valve 3 19 is in an open state. The shell 1 is supported by the support mechanism 6 and is firmly set on the plane. The fluid to be heated or cooled is introduced into the shell 1 from the liquid inlet 1 2, and the fluid enters the tube 15 through the separation plate 14. In the process of the fluid flowing in the tube 15, the fluid passes through the holes on the separation plate 14, which guides the fluid to enter and flow along a predetermined path, so that the flow rate increases and contacts the surface of the heat exchange tube. The guide plate 16 on the tube 15 can help evenly distribute the fluid entering the shell side, ensure that the fluid is well distributed around all tubes, avoid excessively high or low flow rates in some areas, and finally the fluid flows out from the three-way pipe 4. While the fluid to be heated or cooled is introduced into the shell 1, the medium fluid enters the shell 1 through the liquid inlet 2 3, exchanges heat with the fluid to be heated or cooled in the tube 15, and finally flows out from the liquid outlet 2 5. When the heat exchanger needs to be cleaned after working for a period of time, the electric control valve three 19 is closed, and the electric control valve two 18 and the electric control valve one 17 are opened. At this time, the backwashing liquid enters the backwashing pipe 42 and passes into the shell 1 through the electric control valve two 18 to realize the liquid flow direction opposite to the heat exchange process, thereby performing a backwashing operation on the tube 15.

[0020] In certain preferred embodiments, the liquid inlet 1 2 is located on the outer side of the shell 1 compared to the liquid inlet 2 3, and the three-way pipe 4 is located on the outer side of the shell 1 compared to the liquid outlet 2 5, and temperature sensors are installed in the liquid outlet 1 41 and the liquid outlet 2 5, and the temperature sensors in the liquid outlet 1 41 and the liquid outlet 2 5 are both connected to the heat exchange system signal.

[0021] In some preferred embodiments, the support mechanism 6 includes a support 61, which is a structure with a hollow "U"-shaped body on the top and four support columns fixed on the bottom, and the hollow "U"-shaped body of the support 61 is adapted to the outer contour of the shell 1, and the main support effect is provided by the support columns.

[0022] In some preferred embodiments, a shock-absorbing spring 62 is arranged around the support column of the support 61, and a fixing plate 63 is welded to the bottom of the support column of the support 61, thereby achieving a certain shock-absorbing and buffering effect on the shell 1.

[0023] In certain preferred embodiments, Figure 4As shown, a rotating motor 64 is installed on the inner wall of the hollow "U"-shaped body of the support 61, and the rotating motor 64 is connected to the heat exchange system signal. A gear 65 is connected to the upper shaft of the rotating motor 64. A heat preservation plate 66 is installed in the hollow "U"-shaped body of the support 61 to reduce heat loss to the surrounding environment and save energy. Several tooth grooves 67 are evenly installed on the inner walls at both ends of the heat preservation plate 66. A gear 65 is installed at the tooth groove 67 on the side where the rotating motor 64 is not installed. The gear 65 is movably connected to the inner wall of the hollow "U"-shaped body of the support 61 through a connecting rod. The two gears 65 are about the support 61, thereby ensuring the feasibility of the equipment. The tooth groove 67 is meshed with the gear 65. After the rotating motor 64 is started, the gear 65 rotates, so that the gear 65 and the tooth groove 67 are meshed and transmitted, thereby realizing the rotation displacement of the heat preservation plate 66. That is, the insulation board 66 can be retracted into the hollow "U"-shaped body of the support 61, and can also surround the outer side of the shell 1 together with the hollow "U"-shaped body, thereby achieving a certain insulation effect on the heat exchange equipment.

[0024] In some optional embodiments, when the external environment is at a low temperature, the heat exchange efficiency of the heat exchange device will be affected to a certain extent, and at this time, the heat insulation plate 66 installed in the support 61 needs to have a certain heat preservation effect. Specifically, the required temperature of the liquid after heat exchange is set to T, T is set by the heat exchange system, and the actual temperature of the liquid after heat exchange is t1, t1 is fed back by the temperature sensor in the liquid outlet 2 5, and the temperature fed back by the temperature sensor of the liquid outlet 1 41 is t2; When the liquid outlet 41 feeds back that t1 is equal to T, it indicates that the heat exchange efficiency can still be kept stable in the low temperature environment and the equipment is in good condition.

[0025] When the liquid outlet 1 41 feeds back that t1 is greater than T, it indicates that the heat exchange process is excessive and the medium liquid temperature setting is far too high. In order to avoid excessive heat not being effectively utilized, resulting in energy waste, the heat exchange system needs to reduce the medium liquid's inlet temperature and flow rate until the temperature sensor in the liquid outlet 2 5 feeds back that t1 is equal to T.

[0026] When the liquid outlet 41 feedbacks that t1 is less than T, it means that the heat exchange efficiency is greatly affected in the low temperature environment at this time, resulting in insufficient temperature rise of the liquid to be exchanged after passing through the heat exchange equipment. At this time, the heat exchange system will control the insulation plate 66 to start the insulation operation of the shell 1, that is, the heat exchange system drives the rotating motor 64 to rotate, so that the gear 65 rotates accordingly and drives the displacement of the tooth groove 67, thereby realizing the insulation plate 66. Figure 5 to Figure 3 If after a period of time, the temperature sensor in the second liquid outlet 45 feeds back that t1 is equal to T, it indicates that the heat exchange is qualified; If after a period of time, the temperature sensor in the second liquid outlet 45 feeds back that t1 has risen to a certain extent but is still less than T, it means that the equipment after insulation still cannot achieve the required heat exchange effect. At this time, the heat exchange system will compare the t2 value reflected by the temperature sensor in the first liquid outlet 41 with the temperature of the medium liquid before heat exchange, thereby inferring the heat exchange efficiency of the medium liquid, and then increasing the temperature of the medium liquid according to the difference between t1 and T, so that the liquid to be heat exchanged can accurately reach the required heat exchange temperature without wasting energy.

[0027] In some preferred embodiments, a connecting rod 9 is riveted on the reciprocating mechanism 8, a positioning plate 10 is welded to the end of the connecting rod 9, a plurality of brushes 12 are fixed on the positioning plate 10, and the brushes 12 correspond to the tube 15, thereby achieving a joint driving effect of various components.

[0028] In certain preferred embodiments, Figure 6 As shown, the reciprocating mechanism 8 includes a positioning frame 81, which is a rectangular frame structure. A telescopic rod 82 is welded to a section of the positioning frame 81, and the telescopic rod 82 is a structure formed by sliding and fitting multiple tubular parts. The telescopic rod 82 is riveted to the support rod 7, and a tooth column 83 is evenly welded on the inner side of a pair of longer sides of the positioning frame 81. A driving motor 84 is installed inside the support rod 7, and the driving motor 84 is connected to the heat exchange system signal. A ratchet 85 is connected to the upper shaft of the driving motor 84, and the ratchet 85 is meshed and connected with the tooth column 83. After the driving motor 84 is started, the ratchet 85 rotates, and when the gear teeth on the ratchet 85 mesh with the tooth column 83 located above the positioning frame 81, the positioning frame 81 moves toward the direction of the housing 1, and when the gear teeth on the ratchet 85 mesh with the tooth column 83 located below the positioning frame 81, the positioning frame 81 moves in the opposite direction of the housing 1.

[0029] In some preferred embodiments, the side of the positioning frame 81 opposite to the telescopic rod 82 is welded to the connecting rod 9, so that when the reciprocating mechanism 8 is driven, the connecting rod 9 will drive the positioning plate 10 to move back and forth synchronously.

[0030] In certain optional embodiments, based on the above embodiments, when t1 is generally less than T, the temperature t2 of the medium liquid after heat exchange is detected by the temperature sensor in the liquid outlet 41, and t2 is compared with the initial temperature of the medium liquid to calculate the heat exchange efficiency v, and the heat exchange efficiency of the medium liquid under normal circumstances is set to V.

[0031] When v is equal to or greater than V, it means that the heat exchange efficiency of the heat exchange equipment is normal or high, and the liquid to be exchanged can be obtained more quickly at this time; When v is less than V, it means that the heat exchange efficiency is too low. The heat exchange system will stop the liquid inlet 2 and the liquid inlet 3, close the electric control valve 3 19, open the electric control valve 2 18 and the electric control valve 1 17, so that the flushing liquid is pumped to the backwash pipe 42 and then enters the shell 1. At this time, the heat exchange operation has just been carried out in the tube 15, and the temperature in the tube 15 is relatively high. The high temperature will cause the dirt in the tube 15 to undergo physical changes, such as crystallization and solidification, resulting in an increase in the hardness of the dirt. At this time, the system needs to control the cleaning pump on the backwash pipe 42 to adjust the flushing liquid with a lower temperature and a higher flow rate. The flushing liquid flows through the tube 15, so that the dirt on the inner wall of the tube 15 is affected by the impact of the flushing liquid and flows toward the inlet end of the tube 15 where the heat exchange liquid is required, and then is discharged to the wastewater tank 13 through the drain pipe 11. At the same time, the speed of the driving motor 84 is increased to speed up the backwashing and brushing speed, thereby removing the dirt. After multiple reciprocating brushing, the dirt at the mouth of the pipe 15 is brushed out and enters the waste water tank 13 together.

[0032] Based on the above embodiment, in a low temperature environment, in order to save energy, if the temperature t1 of the heat exchange liquid rises slowly after the shell 1 is insulated by the insulation plate 66, the reciprocating mechanism 8 and the brush 12 can be started to circulate and scrub the tube 15 in the shell 1 before the medium liquid is increased, and the flushing liquid is heated at the same time. The heated flushing liquid is pumped to the backwash pipe 42 and then passed into the tube 15, which can better break down the dirt. At the same time, the heat of the backwashing liquid will be transferred to the inner wall of the tube 15, thereby achieving a preheating effect, so that when the heat exchanger is used again, the heat exchanger will reach the normal operating temperature faster, thereby improving the heat exchange efficiency.

[0033] The above embodiment aims at the situation that the heat exchange equipment is inefficient under normal conditions, and uses a backwash liquid with a lower temperature and a higher flow rate in combination with a brush 12 for descaling. When the heat exchange efficiency is low under low temperature conditions, a flushing liquid with a higher temperature is used to pass through the heat exchange equipment to increase the heat exchange with the heat exchanger wall, thereby improving the heat conduction efficiency of the entire system and avoiding energy waste to a large extent.

The heat exchange efficiency v is calculated by comparing t2 with the initial temperature of the medium liquid. The heat exchange efficiency of the medium liquid under normal circumstances is set to V. When v is less than V, it indicates that the heat exchange efficiency is too low. The heat exchange system stops the liquid inlet 1 (2) and the liquid inlet 2 (3), closes the electric control valve 3 (19), opens the electric control valve 2 (18) and the electric control valve 1 (17), so that the flushing liquid is pumped to the backwashing pipe (42) and then enters the shell (1), and flows through the pipe (15), so that the dirt on the inner wall of the pipe (15) flows toward the inlet end of the pipe (15) to be heated after the impact of the flushing liquid, and then is discharged into the waste water tank (13) through the sewage pipe (11). The dirt that has not been flushed out of the end of the pipe (15) is brushed by the brush (12) driven by the reciprocating mechanism (8), so that it is brushed out after repeated brushing and enters the waste water tank (13) together. In a low temperature environment, in order to save energy, if the temperature t1 of the liquid to be heat exchanged rises slowly after the shell (1) is insulated by the insulation plate (66), the reciprocating mechanism (8) and the brush (12) can be started to circulate and scrub the tube (15) in the shell (1) before the medium liquid is raised. At the same time, the flushing liquid is heated. The heated flushing liquid is pumped to the backwashing pipe (42) and then introduced into the tube (15), which can better break down dirt. At the same time, the heat of the backwashing liquid is transferred to the inner wall of the tube (15), thereby achieving a preheating effect. When the heat exchanger is used again, the heat exchanger will reach the normal operating temperature more quickly, thereby improving the heat exchange efficiency.
