Description

Technical Field

[0001] This invention relates to the field of boilers, and in particular to a low-temperature water supply condenser specifically designed for livestock farms. Background Technology

[0002] The condenser of the boiler in the farm is equipped with a water supply device. By spraying water in the form of water mist, the discharged steam is cooled rapidly, thereby improving the system vacuum and thermal economy. In addition, it will increase the temperature of the water entering the deaerator and reduce the oxygen content, thereby improving the deaerator's deoxygenation efficiency. The water supply device can reduce the boiler's energy consumption and lower the operating cost of the boiler in the farm.

[0003] After the water leaves the atomizing nozzle, it comes into contact with the condenser in the form of a water mist. The water mist is not evenly distributed on the condenser surface, which can easily lead to uneven temperature distribution on the condenser surface during condensation, increasing the risk of condenser damage. Secondly, the utilization rate of the water mist is not high; most of the water mist dissipates freely rather than concentrating on the condenser surface. Furthermore, when steam passes through the condenser pipes, most of the heat exchange is concentrated on the steam in contact with the pipe walls, while the temperature of the steam in the middle of the pipes remains relatively high. The purpose of this invention is to propose a new water-filled condenser structure to solve the above problems and promote the development of technology in this field. Summary of the Invention

[0004] The purpose of this invention is to provide a low-temperature water replenishment condenser specifically for aquaculture farms, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including a cavity, a ring, a connecting ring, a limiting block, a rotating ring, a gear ring, a motor, and blades. The cavity is provided with a condenser pipe, a drain pipe, and an atomizing pipe with an atomizing nozzle. The condenser pipe is connected to a steam pipe to achieve steam condensation. The number of condenser pipes can be adjusted by technicians according to actual needs in specific implementations. The drain pipe is used to discharge liquefied water. The atomizing pipe is connected to an external water supply pipe to spray low-temperature water from the atomizing nozzle.

[0006] The ring is located inside the condenser tube and forms a sliding pair along the length of the condenser tube. The ring is magnetically attracted and fixed inside the condenser tube. The ring and the condenser tube are dynamically fixed by magnetic attraction rather than by traditional welding / bolting, which makes later maintenance convenient.

[0007] The connecting ring and the circular ring form a rotating pair, and a through hole is formed on the connecting ring, through which steam and liquefied water can flow.

[0008] The limiting block is located at the front end of the connecting ring and fixed to the connecting ring. The limiting block refers to a block-shaped component that plays a limiting role. Its purpose is to reduce space and promote the contact between steam and the condenser tube wall. A conical connecting column is formed at the front end of the limiting block. Fan blades are provided on the side of the connecting column. A guide block is provided at the front end of the connecting column. Steam can diffuse towards the condenser tube wall through the guide block, which helps the steam to fully contact the condenser tube wall and perform heat exchange.

[0009] The rotating ring is located at the rear end of the circular ring and forms a rotating pair with the circular ring. The front end of the rotating ring is connected to the connecting ring. When the rotating ring rotates, it can drive the connecting ring to rotate synchronously.

[0010] The gear ring is set on the outside of the condenser tube through a bearing ring and forms a rotating pair with the condenser tube. The rotating ring and the gear ring attract each other and can be driven by the gear ring.

[0011] The motor is located outside the cavity, and the motor shaft is equipped with gears that mesh with a gear ring. The motor is controlled automatically by an external controller. The controller's control circuit can be easily programmed by those skilled in the art. The power supply is also common knowledge in the field. Since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0012] The blades are located outside the condenser tube and are arranged along the length of the condenser tube. The blades are evenly distributed on the side of the condenser tube. One end of the blade is connected to the gear ring, and the other end is set on the condenser tube through the bearing ring.

[0013] To optimize the above technical solution, further measures are taken, including a scraper with a groove formed on the side of the connecting column. A spring is set in the groove, with the scraper and the groove connected at both ends respectively. If it is necessary to clean the scale adhering to the inner wall of the condenser tube, the motor power is increased to increase the speed of the gear ring. At this time, under the action of centrifugal force, the spring will extend and make the scraper move closer to the condenser tube wall. After the scraper contacts the condenser tube wall, the scale can be cleaned. When the speed of the gear ring is less than the speed at which the scale cleaning operation is performed, the scraper does not contact the condenser tube wall and will not affect the normal operation of the equipment.

[0014] As a further improvement to the above technical solution: a corrugated plate is formed on the side of the limiting block. The corrugated plate is arranged along the axial direction of the limiting block and the corrugated plates are evenly distributed on the side of the limiting block. The corrugated plate refers to a plate-shaped component with a wave shape. Its purpose is to increase the turbulence of the steam and promote full contact between the steam and the condenser tube wall to achieve heat exchange.

[0015] As a further improvement to the technical solution: a first magnetic ring is embedded inside the circular ring, and a second magnetic ring is sleeved on the outside of the condenser tube. The first and second magnetic rings attract each other to fix the position of the circular ring inside the condenser tube.

[0016] As an improvement to the aforementioned technical solution: a third magnet ring is provided on the rotating ring, and a fourth magnet ring is provided on the gear ring. The third and fourth magnet rings attract each other, thereby enabling the rotating ring and the gear ring to attract each other and be driven by the gear ring. The first, second, third, and fourth magnet rings refer to ring-shaped components made of magnets or mainly made of magnets. The serial numbers such as first, second, etc., are only used to indicate the order and have no actual meaning. In specific implementation, technicians can change the magnetic force by changing the material or specifications of the magnet rings. It should be noted that the Curie point temperature of the magnet ring should be greater than the working temperature of the magnet ring.

[0017] Furthermore, the front end of the ring is beveled and the surface of the ring is coated with polytetrafluoroethylene (PTFE). The beveled structure facilitates the passage of steam and liquefied water. The PTFE coating has good chemical corrosion resistance, high temperature resistance, and an extremely low surface friction coefficient. Its purpose is to improve surface lubrication and inhibit scale formation.

[0018] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

[0019] A. It can guide water mist to fully surround the condenser tube, which can improve the water mist utilization efficiency and ensure that the surface temperature of the condenser tube is evenly distributed, avoiding deformation of the condenser tube due to uneven water mist distribution;

[0020] B. The internal components of the condenser tube are dynamically fixed by magnetic attraction, which can buffer the components when subjected to instantaneous steam impact, thus avoiding damage to the components and making disassembly and assembly convenient for subsequent inspection and maintenance.

[0021] C. The limiting block and connecting column fill the middle of the condenser tube, and the water mist evenly surrounds the condenser tube on the outside. The steam inside the condenser tube is guided by the limiting block and connecting column and can evenly cover the inner side of the condenser tube wall, which helps to improve the condensation efficiency of the condenser tube.

[0022] D. It can automatically clean the scale formed on the inner wall of the condenser tube, making maintenance convenient. Attached Figure Description

[0042] Example 2: Please refer to Figure 1-8 The present invention provides a low-temperature water replenishment condenser for aquaculture farms, comprising a cavity 100, a circular ring 200, a connecting ring 300, a limiting block 400, a rotating ring 500, a gear ring 600, a motor 700, blades 800 and a scraper 900.

[0044] The connecting ring 300 and the circular ring 200 form a rotating pair.

[0045] The limiting block 400 is located at the front end of the connecting ring 300 and fixed to the connecting ring 300.

The corrugated plates 404 are arranged along the axial direction of the limiting block 400 and each corrugated plate 404 is equally spaced on the side of the limiting block 400.

[0046] The rotating ring 500 is located at the rear end of the circular ring 200 and forms a rotating pair with the circular ring 200. The front end of the rotating ring 500 is connected to the connecting ring 300.

[0047] The gear ring 600 is disposed outside the condenser tube 101 and forms a rotating pair with the condenser tube 101. The rotating ring 500 and the gear ring 600 attract each other and can be driven by the gear ring 600. A third magnet ring 501 is disposed on the rotating ring 500 and a fourth magnet ring 601 is disposed on the gear ring 600. The third magnet ring 501 and the fourth magnet ring 601 attract each other, so that the rotating ring 500 and the gear ring 600 can be driven by the gear ring 600.

[0048] The motor 700 is located outside the cavity 100, and the motor 700 shaft is equipped with a gear 701 that meshes with the gear ring 600.

[0049] The blades 800 are located outside the condenser tube 101 and are arranged along the length of the condenser tube 101. The blades 800 are evenly distributed on the side of the condenser tube 101. One end of the blade 800 is connected to the gear ring 600 and the other end is set on the condenser tube 101 through the bearing ring.

[0050] A groove 901 is formed on the side of the connecting column 401, and a spring is set in the groove 901. The two ends are connected to the scraper 900 and the groove 901 respectively.

[0051] Working principle: Steam is input into the condenser tube 101. During the process, the atomizing nozzle 103 on the atomizing tube 104 sprays low-temperature water mist to cool the condenser tube 101 and recover heat. The water mist that recovers heat is finally collected and discharged from the drain pipe 102 of the cavity 100 in the form of water flow and then used in other sections.

[0052] In Embodiments 1 and 2, the motor 700, in cooperation with the gear 701 and the gear ring 600, drives the rotating ring 500 to rotate using the third magnet ring 501 and the fourth magnet ring 601, causing the fan blades 402 to move synchronously. The rotating fan blades 402 can force steam into the gap between the condenser tube 101 wall and the connecting column 401, allowing the tube wall to exchange heat with the steam for condensation. The connecting column 401 is tapered with a small front cross-sectional area, which helps the gap to accommodate steam. The rear cross-sectional area of ​​the connecting column 401 is larger than that of the front, which helps to compress the steam and make the droplets fully contact the condenser tube 101 wall.

[0053] After passing through the connecting column 401, the steam enters the gap between the limiting block 400 and the wall of the condenser tube 101. During the process, the corrugated plate 404 on the surface of the limiting block 400 can increase the turbulence of the steam, so that the steam liquid can fully collide with the wall of the condenser tube 101 to achieve heat exchange. Finally, the steam that has been condensed leaves the end of the condenser tube 101 in the form of condensate through the connecting ring 300. During the process, the fan blade 402 rotates continuously, and the airflow helps to drive the condensate through the connecting ring 300.

[0054] Since the blade 800 is connected to the gear ring 600, the blade 800 will also continuously rotate around the condenser tube 101 during the condensation process. When the atomizing nozzle 103 sprays water mist, the water mist will be evenly surrounded by the condenser tube 101 due to the airflow stirred by the blade 800. This can solve the problem of uneven distribution of water mist on the surface of the condenser tube 101 and improve the utilization effect of water mist. At the same time, the airflow can also improve the heat dissipation of the surface of the condenser tube 101 and ensure the condensation effect of steam.

[0055] The ring 200 is fixed inside the condenser tube 101 by the mutual attraction between the first magnetic ring 201 and the second magnetic ring 105, rather than by welding or bolting or other common methods. When the components inside the condenser tube 101 are subjected to instantaneous steam impact, the ring 200 can move laterally along the condenser tube 101, prolonging the time the components are subjected to steam impact and reducing the peak impact force, which can prevent damage to the components. At the same time, the magnetic attraction method makes the components easy to disassemble and facilitates subsequent maintenance.

[0056] In Example 2, after scale forms on the inner wall of the condenser tube 101, the operator can increase the speed of the motor 700 to accelerate the rotation of the connecting column 401. At this time, under the action of centrifugal force, the spring will extend so that the scraper 900 presses against the inner wall of the condenser tube 101, which can clean the scale and prevent the scale from affecting the heat exchange efficiency.
