Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment technology, specifically a split-type coal-to-electricity heat exchange device. Background Technology

[0002] Split-type coal-to-electricity heat exchangers are a clean energy alternative proposed to address the problems of inefficient heating and pollution emissions in rural and urban areas of my country. Coal, as a traditional heating energy source, produces a large number of pollutants during combustion, such as sulfur dioxide, nitrogen oxides, and particulate matter, which seriously affect air quality and human health. With the gradual tightening of my country's environmental protection policies and the promotion of the concept of sustainable development, coal heating is gradually being replaced by clean energy. However, due to its structure and working environment, the pipes inside the heat exchanger are prone to accumulating dirt and deposits during long-term operation, which affects its heat exchange efficiency, increases energy consumption, and may even lead to equipment damage. Therefore, regular cleaning of the heat exchanger is the key to ensuring its efficient operation.

[0003] Utility model patent CN223243405U discloses a split-type heat exchange device. The medium outlet of a first heat exchanger is connected to the medium inlet of a second heat exchanger via a first pipe, and the medium outlet of the second heat exchanger is connected to the medium inlet of the first heat exchanger via a second pipe. A compressor is installed on either the first or second pipe. The first heat exchanger has a first tube sheet at one end and a second tube sheet at the other end within its shell. The first and second tube sheets divide the heat exchanger shell into a first collecting chamber, a heat exchange chamber, and a second collecting chamber. Heat exchange tubes are installed between the first and second tube sheets within the heat exchange chamber. A heat-conducting medium flows through the gap between the heat exchange tubes and the heat exchanger shell. The heat exchange tubes are connected to the first and second collecting chambers. The heat exchanger shell has a main fluid inlet connected to the first collecting chamber and a main fluid outlet connected to the second collecting chamber. This utility model reduces the heat exchange temperature difference, improves the efficiency of the heat exchange equipment, reduces scaling, corrosion, and clogging, and extends the service life of the heat exchange equipment.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model discloses a split-type coal-to-electricity heat exchanger, including a heat exchanger body 1 and a tube box 2 disposed at one end of the heat exchanger body 1. An end cap 3 is fixedly connected to one end of the tube box 2. The device also includes a partition plate 4 disposed in the middle of the tube box 2, with a high-pressure flushing assembly 5 fixedly connected to the surface of the partition plate 4.

A water pipe connector 6 is fixedly connected to the other end of the inlet pipe 502. A shell is disposed on the surface of the heat exchanger body 1. The body 7 has a mounting assembly 8 fixedly connected to its surface. The mounting assembly 8 includes a silicone ring 801, an upper support plate 802, and a lower support plate 803. A support base 9 is fixedly connected to the bottom of the lower support plate 803. A connecting pipe 10 is provided at one end of the diversion pipe 503. A rotating nozzle assembly 11 is fixedly connected to the other end of the connecting pipe 10. The rotating nozzle assembly 11 includes a nut tube 1101, a ball joint 1102, and a high-pressure nozzle 1103. A protective cover 12 is fixedly connected to one end of the high-pressure nozzle 1103.

[0020] Specifically, the high-pressure flushing assembly 5 includes a high-pressure water pan 501 fixedly connected to the surface of the partition plate 4. A water inlet pipe 502 is fixedly connected to one side of the high-pressure water pan 501, and several diversion pipes 503 are fixedly connected to the other side of the high-pressure water pan 501.

[0021] In this implementation scheme, high-pressure water is drawn through the inlet pipe 502 and stably delivered to the high-pressure water pan 501. The high-pressure water is received from the inlet pipe 502 and evenly distributed within the high-pressure water pan 501, providing a stable pressure foundation for subsequent diversion. The concentrated high-pressure water flow within the high-pressure water pan 501 is evenly distributed to each diversion pipe 503. Through a reasonable layout, several sets of rotating nozzle assemblies 11 can effectively increase the efficiency of flushing multiple sets of pipes in the middle of the heat exchanger body 1. The impact force of the high-pressure water flow achieves the functions of decontamination, slag removal, and cleaning and unblocking.

[0022] Specifically, the mounting component 8 includes a silicone ring 801 fixedly connected to the surface of the housing 7, with an upper support plate 802 sleeved on the upper surface of the silicone ring 801 and a lower support plate 803 sleeved on the lower surface of the silicone ring 801.

[0023] In this embodiment, the upper support plate 802 and the lower support plate 803 are connected by a rotating shaft 13, allowing the upper support plate 802 to rotate around the lower support plate 803. The rotating shaft 13 is connected to the transmission block 14, which fixes the upper support plate 802 and the lower support plate 803 and transmits torque. The rotating nut 17 on the other side of the upper support plate 802 and the lower support plate 803 is threadedly connected to the surface of the threaded rod 16. The rotating nut 17 can be manually adjusted to tighten or loosen the upper support plate 802 and the lower support plate 803. At the same time, the pressure silicone ring 801 is fixed to the surface of the housing 7, effectively protecting the surface of the housing 7 from wear.

[0024] Specifically, the rotary nozzle assembly 11 includes a nut tube 1101 fixedly connected to the other end of the connecting tube 10, a ball joint 1102 rotatably connected to the other end of the nut tube 1101, and a high-pressure nozzle 1103 fixedly connected to the other end of the ball joint 1102.

[0025] In this embodiment, high-pressure water is drawn through the inlet pipe 502, and the concentrated high-pressure water flow in the high-pressure water pan 501 is evenly distributed to each branch pipe 503. The high-pressure water flow enters the connecting pipe 10, which is fixedly connected to one end of the branch pipe 503, providing a stable transition interface to stably connect the high-pressure nozzle 1103 and the ball joint 1102, ensuring that the high-pressure water does not leak during the flow process and can also withstand a certain pressure. The ball joint 1102 is located in the middle of one end of the nut pipe 1101 and is rotatably connected to the nut pipe 1101. The ball joint 1102 provides a flexible rotational connection, and the high-pressure water nozzle can be adjusted at different angles and directions. The ball joint 1102 rotates due to the impact of the high-pressure water, so that the high-pressure nozzle 1103 maintains a stable high-pressure jet while rotating.

[0026] Specifically, two sets of rotating shafts 13 are rotatably connected to one side of the upper support plate 802 and the lower support plate 803, and a transmission block 14 is sleeved on the surface of the rotating shaft 13.

[0027] In this embodiment, the upper support plate 802 and the lower support plate 803 are connected by a rotating shaft 13, so that the upper support plate 802 can rotate around the lower support plate 803. The upper support plate 802 and the lower support plate 803 are connected by a transmission block 14 through the rotating shaft 13, so that the upper support plate 802 and the lower support plate 803 are fixed and torque is transmitted.

[0028] Specifically, a connecting shaft 15 is rotatably connected to the other side of the upper support plate 802 and the lower support plate 803, and a threaded rod 16 is fixedly connected to the surface of the connecting shaft 15.

[0029] In this embodiment, the connecting shaft 15 serves as a rotating connection structure between the upper support plate 802 and the lower support plate 803, allowing the upper and lower support plates 803 and the threaded rod 16 to open and close relative to each other and rotate. At the same time, it provides stable fixed support for the threaded rod 16, ensuring that the structure does not deviate during transmission.

[0030] Specifically, a rotating nut 17 is rotatably connected to the top of the threaded rod 16, and a rotating handle 18 is fixedly connected to the surface of the rotating nut 17.

[0031] In this embodiment, the rotating nut 17 on the other side of the upper support plate 802 and the lower support plate 803 is connected to the surface of the threaded rod 16 by thread. The rotating handles 18 on both sides of the rotating nut 17 can be manually adjusted to tighten or loosen the upper support plate 802 and the lower support plate 803.

[0032] Specifically, an outlet pipe 19 is fixedly connected to the top of the housing 7, an inlet pipe 20 is fixedly connected to the bottom of the housing 7, and a support frame 21 is fixedly connected to the bottom of the support base 9.

[0033] In this embodiment, the inlet pipe 20 serves as the inlet for external refrigerant to enter the heat exchanger. It flows inside the shell 7, where the refrigerant evaporates, absorbs heat, and turns into gas, which is then discharged from the outlet pipe 19 at the top of the shell 7, thus achieving a complete refrigerant circulation with directional discharge. The support frame 21 bears the entire weight of the equipment and serves as the stable installation foundation for supporting the equipment.

[0034] The working principle and usage process of this utility model are as follows: To prevent the accumulation of sediment and dirt inside the pipes, high-pressure water is drawn through the inlet pipe 502, and the external high-pressure water flow is stably delivered to the high-pressure water pan 501. This pan receives the high-pressure water flow input from the inlet pipe 502 and simultaneously ensures that the high-pressure water is evenly distributed within the high-pressure water pan 501, providing a stable pressure foundation for subsequent diversion. The concentrated high-pressure water flow within the high-pressure water pan 501 is evenly distributed to each diversion pipe 503. Through a reasonable layout, several sets of rotating nozzle assemblies 11 can effectively increase the efficiency of flushing multiple sets of pipes in the middle of the heat exchanger body 1. The impact force of the high-pressure water flow achieves decontamination and cleaning. The heat exchanger has the functions of cleaning and unblocking, and facilitates the installation and disassembly of the heat exchanger by the staff. The upper support plate 802 and the lower support plate 803 are connected by a rotating shaft 13, so that the upper support plate 802 can rotate around the lower support plate 803. The rotating shaft 13 is connected to the transmission block 14, so that the upper support plate 802 and the lower support plate 803 are fixed and the torque is transmitted. The rotating nut 17 on the other side of the upper support plate 802 and the lower support plate 803 is connected to the surface of the threaded rod 16 by a thread. The rotating nut 17 can be manually adjusted to tighten or loosen the upper support plate 802 and the lower support plate 803. At the same time, the pressure silicone ring 801 is fixed to the surface of the shell 7, effectively protecting the surface of the shell 7 from wear.

[0035] In summary, this split-type coal-to-electricity heat exchanger, through the high-pressure flushing component 5, effectively achieves regular high-pressure jet flushing of the heat exchanger, preventing the accumulation of deposits and dirt inside the pipes, maintaining the efficient operation of the heat exchanger, reducing maintenance costs, and extending the service life of the equipment. Furthermore, the installation component 8 facilitates the installation, adjustment, and disassembly of the heat exchanger by staff, improving operational and maintenance efficiency and providing better stability and functionality.
