Description

Technical Field

[0001] This utility model relates to the field of steam heat exchange technology, and specifically to steam heat exchange units. Background Technology

[0002] When controlling the water heater to heat water, it contains a gas heating device that uses gas to heat the liquid inside the circulation pipe, generating steam. At the same time, the steam is transported to the inside of the heat exchange box, where the steam can heat the liquid inside the heat exchange box, thus using the heat energy in the steam to perform heat exchange treatment on the liquid.

[0003] A search revealed that patent application CN202420259279.4 discloses a steam heating unit that increases the heating time of the liquid by changing the flow rate of steam and the liquid to be heated, thereby improving the heating efficiency of the equipment. However, this device lacks a dedicated, high-efficiency drainage component for steam condensate. If condensate accumulates inside the equipment, it may affect steam flow and reduce the stability of equipment operation. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a steam heat exchanger unit, which solves the problems mentioned in the background art.

[0005] The solution of this utility model to the above-mentioned technical problems is as follows:

[0006] A steam heat exchanger unit includes a tank body, with a first end cover and a second end cover installed at both ends of the tank body, and a support installed at the bottom end of the tank body;

[0007] The first end cap has a partition inside, which divides the first end cap into a first cavity and a third cavity. The upper and lower sides of the first end cap are respectively provided with a steam inlet pipe and a steam outlet pipe.

[0008] The tank body has a heat exchange cavity inside, and heat exchange conduits are evenly installed in the heat exchange cavity. The upper and lower sides of the tank body are respectively provided with a liquid outlet pipe and a liquid inlet pipe. The second end cap is provided with a second cavity. The second cavity is connected to the first cavity and the third cavity through heat exchange conduits. The bottom of the second cavity is provided with a drain assembly.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the drainage assembly includes a sleeve, and a cap is installed inside the sleeve via a connecting plate. A drainage pipe is provided on the sleeve, and the cap covers the drainage pipe. The water accumulated in the second cavity is drained through the siphon principle generated by the cooperation between the drainage pipe and the cap.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] By utilizing the siphon principle, the system achieves non-powered drainage, eliminating the need for additional power equipment such as water pumps. This simplifies the structure and reduces equipment costs and energy consumption. Simultaneously, the component can automatically sense the water level in the second cavity. When the water reaches a certain height and forms siphon conditions, it can promptly drain the water, preventing condensate buildup from affecting steam heat exchange efficiency or corroding the inner wall of the equipment. This ensures stable equipment operation and reduces maintenance frequency.

[0013] Furthermore, a through hole is provided through the partition plate, and the first cavity and the third cavity are connected through the through hole.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The through-hole design increases the airflow velocity within the third cavity. According to fluid mechanics principles, increased flow velocity reduces local pressure, thereby effectively reducing the flow resistance of steam within the heat exchange duct. This allows for smoother steam flow within the heat exchange system, preventing steam blockage or accumulation within the pipes. Simultaneously, the optimized steam flow path enables more thorough heat exchange between the steam and the liquid outside the heat exchange duct, improving overall heat exchange efficiency and reducing energy loss.

[0016] Furthermore, the first end cap and the second end cap are respectively installed at both ends of the tank via flanges.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] Flange connections offer excellent sealing, effectively preventing steam and liquid leaks and ensuring safe equipment operation. Furthermore, this connection structure facilitates disassembly and installation. When equipment malfunctions or requires regular maintenance or cleaning of internal components, the end caps can be quickly removed, allowing maintenance personnel to inspect, repair, or replace heat exchange pipes, drainage components, and other internal components. This reduces equipment downtime and improves the convenience and efficiency of equipment maintenance.

[0019] Furthermore, the outlet pipe and the inlet pipe are diagonally distributed.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The diagonal distribution design promotes more thorough convection of the liquid within the heat exchange cavity of the tank, extending the residence time of the liquid in the heat exchange cavity and enabling more complete heat exchange with the heat exchange conduits, thereby improving the heating effect and uniformity of the liquid. At the same time, the reasonable liquid flow path avoids local dead zones or short circuits, ensuring that the liquid is heated evenly throughout the entire heat exchange area, thus improving the overall heat exchange performance and operational stability of the steam heat exchanger unit.

[0022] This utility model provides a steam heat exchanger unit. It has the following beneficial effects:

[0023] The heat exchange tubes inside the tank are evenly installed in the heat exchange cavity, which increases the heat exchange area between steam and liquid, allowing heat to be transferred more fully and improving heat exchange efficiency.

[0024] The liquid outlet and inlet pipes are diagonally distributed. This design helps the liquid form a better flow path in the heat exchange cavity, allowing the liquid to participate in heat exchange more evenly and further improving the heat exchange effect.

[0025] The second end cap has a second cavity. The drainage component at the bottom of the cavity uses the siphon principle to drain the water in the second cavity. This can promptly remove condensate and other water generated during the heat exchange process, preventing excessive water accumulation from affecting the heat exchange effect or damaging the equipment, and helping to maintain the normal operation of the equipment.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0034] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows:

[0035] Example 1

[0036] The steam heat exchanger unit includes a tank body 2. A first end cover 1 and a second end cover 3 are installed at both ends of the tank body 2. The first end cover 1 and the second end cover 3 are respectively installed at both ends of the tank body 2 via flanges. This flange connection method provides good sealing performance, effectively preventing steam and liquid leakage and ensuring the safety of equipment operation. At the same time, this connection structure facilitates disassembly and installation. When the equipment malfunctions or requires regular maintenance or cleaning of internal components, the end covers can be quickly disassembled, allowing maintenance personnel to easily inspect, repair, or replace the heat exchange pipes 202, drainage components 301, etc., inside the tank body 2. This shortens equipment downtime and improves the convenience and efficiency of equipment maintenance. A bracket 4 is installed at the bottom of the tank body 2. A partition 103 is installed inside the first end cover 1. The partition 103 divides the space into a first cavity 102 and a third cavity 105. A through hole 104 is provided through the partition 103, and the first cavity 102 and the third cavity 105 are connected through the through hole 104. The through hole 104 increases the airflow velocity in the third cavity 105. According to the principle of fluid mechanics, the increased flow velocity can reduce the local pressure, thereby effectively reducing the flow resistance of steam in the heat exchange duct 202, making the steam flow more smoothly in the heat exchange system, and avoiding the steam from being blocked or accumulating in the pipe. At the same time, the optimized steam flow path allows the steam to exchange heat more fully with the liquid outside the heat exchange duct 202, improving the overall heat exchange efficiency and reducing energy loss. The upper and lower sides of the first end cover 1 are respectively provided with a steam inlet pipe 101 and a steam outlet pipe 106.

[0037] Example 2

[0038] To improve the heat exchange efficiency of steam heat exchanger units, ensure stable equipment operation, and reduce energy consumption, for example, such as Figures 1 to 3As shown, this utility model also includes: a heat exchange cavity 204 is provided inside the tank body 2, and heat exchange conduits 202 are evenly installed in the heat exchange cavity 204. An outlet pipe 201 and an inlet pipe 203 are respectively provided on the upper and lower sides of the tank body 2. The outlet pipe 201 and the inlet pipe 203 are diagonally distributed. This diagonal distribution design promotes more thorough convection of the liquid in the heat exchange cavity 204 of the tank body 2, prolonging the residence time of the liquid in the heat exchange cavity 204, allowing for more thorough heat exchange with the heat exchange conduits 202, improving the heating effect and uniformity of the liquid. Simultaneously, the reasonable liquid flow path avoids local dead zones or short circuits, ensuring uniform heating of the liquid throughout the entire heat exchange area, improving the overall heat exchange performance and operational stability of the steam heat exchanger unit. A second cavity 302 is provided inside the second end cover 3, and the second cavity 302 is connected to the heat exchange conduits 202. The second cavity 302 is not connected to the first cavity 102 and the third cavity 105. The bottom end of the second cavity 302 is provided with a drainage assembly 301. The drainage assembly 301 includes a sleeve 305. A cap 306 is installed inside the sleeve 305 through a connecting plate 303. A drainage pipe 304 is provided on the sleeve 305. The cap 306 covers the drainage pipe 304. The water in the second cavity 302 is discharged by the siphon principle generated by the cooperation of the drainage pipe 304 and the cap 306. The siphon principle is used to realize non-powered drainage, eliminating the need for additional power equipment such as water pumps, simplifying the structure and reducing equipment costs and energy consumption. At the same time, the assembly can automatically sense the water level in the second cavity 302. When the water reaches a certain height and forms a siphon condition, the water can be discharged in time, avoiding the accumulation of condensate that affects the steam heat exchange efficiency or corrodes the inner wall of the equipment, ensuring stable operation of the equipment and reducing maintenance frequency.

[0039] Working principle:

[0040] High-temperature steam enters the first cavity 102 through the steam inlet pipes 101 on both sides of the first end cover 1. Due to the separation effect of the baffle 103 inside the first end cover 1, the steam initially gathers in the first cavity 102. At this time, the steam will flow along the heat exchange conduit 202 connected to the first cavity 102 and enter the second cavity 302 of the second end cover 3. In this process, the heat exchange conduit 202 provides a channel for heat exchange between the steam and the liquid inside the tank 2. Heat transfer between the steam and the liquid is realized through the pipe wall. The high-temperature steam conducts heat to the liquid outside the pipe, realizing preliminary heat exchange.

[0041] The steam entering the second cavity 302 will flow again through another set of heat exchange conduits 202 to the third cavity 105 of the first end cover 1. During the process of the steam flowing from the second cavity 302 to the third cavity 105, it will continuously exchange heat with the liquid in the heat exchange conduit 202 and further transfer its own heat to the liquid.

[0042] After two heat exchanges, the steam has released a significant amount of heat, its temperature has decreased, and it is finally discharged from the equipment through the steam outlet pipe 106 corresponding to the third cavity 105. Meanwhile, in the heat exchange cavity 204 of tank 2, the liquid flows in from the inlet pipe 203, flowing along a predetermined diagonal path, making full contact with the steam in the heat exchange conduit 202, and continuously absorbing heat. Because the inlet pipe 203 and the outlet pipe 201 are diagonally distributed, good convection is formed within the heat exchange cavity 204, ensuring uniform heating of the liquid. The heated liquid flows out from the outlet pipe 201, completing the entire heating process.

[0043] The through hole 104 on the partition plate 103 of the first end cap 1 connects the first cavity 102 and the third cavity 105, allowing steam to pass quickly through the through hole 104 and increasing the airflow velocity in the third cavity 105. According to fluid mechanics principles, increased flow velocity reduces local pressure, thereby reducing the flow resistance of steam in the heat exchange conduit 202. This allows steam to flow more smoothly in the heat exchange conduit 202, preventing steam accumulation due to excessive resistance and affecting heat exchange efficiency.

[0044] During the continuous heat exchange and condensation of steam, the generated condensate accumulates in the second cavity 302. The drainage assembly 301 at the bottom of the second end cover 3 then comes into play. It consists of a sleeve 305, a connecting plate 303, a cap 306, and a drainage pipe 304. Utilizing the siphon principle formed by the drainage pipe 304 and the cap 306, when the condensate in the second cavity 302 reaches a certain level, the siphon effect is activated. Without additional power, the condensate can be automatically discharged from the drainage pipe 304, preventing condensate accumulation from affecting the equipment's operating efficiency and service life.
