Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat energy recovery and utilization, and in particular to a condensate recovery and heating device. Background Technology
[0002] In industrial production, building heating, and other fields, steam equipment (such as boilers, steam turbines, and heat exchangers) generates a large amount of high-temperature condensate during operation. This condensate not only contains significant residual heat (typically between 60-100℃) but may also carry impurities such as rust, mineral particles, and oil. Traditional condensate treatment methods primarily suffer from the following problems.
[0003] Existing heating systems operate independently, heating the circulating water with steam via a heat exchanger and then recovering the condensate. However, the recovered condensate is only used to replenish other equipment, resulting in significant heat loss and waste. Furthermore, during its formation, the condensate comes into contact with the inner walls of pipes, potentially carrying rust, silt, and other particulate impurities, or becoming contaminated with oil and chemical pollutants due to system leaks. If reused directly in the heating system without effective filtration, it can easily cause pipe blockage, heat exchanger scaling, or equipment corrosion, significantly reducing the system's lifespan. Therefore, we propose a condensate recovery heating device. Utility Model Content
[0004] To address the technical problems of heat waste in heating systems and impurities carried by condensate, this utility model provides a condensate recovery heating device.
[0005] This utility model is achieved using the following technical solution: a condensate recovery heating device, comprising a condensate collection mechanism, the condensate collection mechanism including a condensate collection pipe, one end of the condensate collection pipe being connected to a condensate collection tank, the outlet end of a water pump in the condensate collection tank being connected to one end of a circulating pump pipe, the other end of the circulating pump pipe being connected to a heat exchanger, three sets of pipes extending from the heat exchanger, one set being a circulating water inlet pipe, one set being a condensate outlet pipe, and one set being a circulating water outlet pipe; the other end of the circulating water inlet pipe being connected to a hot water circulating tank, the other end of the condensate outlet pipe being connected to a transfer dish, the top of the transfer dish being provided with a matching cover plate, a condensate filtration mechanism being installed inside the transfer dish, a mounting base being fixedly installed on the side wall of the transfer dish, and a water level sensor for detecting the water level being installed inside the transfer dish.
[0006] The condensate filtration mechanism includes a mounting base, a motor is fixedly connected to the top of the mounting base, a drive disc is connected to the output end of the motor, the other end of a shaft is hinged to the edge of the drive disc, and a moving plate is connected to the other end of the shaft.
[0007] The motion plate is slidably connected inside the limiting frame. A limiting groove is opened on the surface of the motion plate. A limiting post is provided on the limiting frame. The limiting post is slidably connected in the limiting groove. A purification component is fixedly connected to the surface of the motion plate.
[0008] The bottom of the motion board is integrally formed with a motion frame, and a connecting shaft is connected to the motion frame. One end of the receiving frame is hinged to the connecting shaft, and the other end of the receiving frame is hinged to a deflection shaft. A transverse moving frame is connected to the outside of the deflection shaft. The transverse moving frame is slidably connected in a transverse positioning groove. A positioning rod is provided on the transverse moving frame. A positioning plate is fixedly connected to the inside of the transverse positioning groove. A sliding groove is opened on the surface of the positioning plate, and the positioning rod is slidably connected in the sliding groove. A purification component is fixedly connected to the surface of the transverse moving frame.
[0009] The motor is fixed to the mounting base, and its output drives the drive disc to rotate. The drive disc is an eccentric wheel structure, and the hinged shaft at the edge oscillates back and forth with the rotation of the drive disc, thereby pushing the moving plate to perform linear reciprocating motion within the limiting frame. The limiting groove on the surface of the moving plate slides in engagement with the limiting post on the limiting frame, ensuring that the moving plate slides smoothly along a fixed trajectory and avoids deviation. The moving plate drives the purification head to reciprocate synchronously through the connecting plate; the moving frame at the bottom of the moving plate is hinged to the receiving frame through the connecting shaft, and the other end of the receiving frame is hinged to the transverse moving frame through the deflection shaft. The transverse moving frame can slide laterally within the transverse sliding groove, causing the purification head to produce a small transverse oscillation during the filtration process for transverse purification; the condensate is also stirred at the same time, improving the purification efficiency; the purification head reciprocates within the transfer dish, continuously filtering the flowing condensate and preventing impurities from accumulating and clogging the pipes.
[0010] As a further optimization of this utility model, the purification component includes a connecting plate, which is mounted on a transverse moving frame and a moving plate. A purification head is fixedly mounted on the surface of the connecting plate. The purification head includes a stainless steel frame and activated carbon particles filled within the frame, with the frame fixedly connected to the connecting plate. The purification head adopts a composite structure of "stainless steel frame + activated carbon particles," and the filled activated carbon particles adsorb soluble pollutants such as organic matter, oil, and heavy metal ions, achieving multi-stage purification.
[0011] As a further optimization of this utility model, a heat exchanger is connected to the outside of the collection tank. The heat exchanger performs heat exchange operations, with high-temperature condensate entering the internal loop of the heat exchanger. Water from the hot water circulation tank also enters the heat exchanger, and the high temperature of the condensate heats the water flowing outside the loop. The heated water is then discharged from the circulation water outlet pipe, achieving efficient heat transfer. The treated condensate is cooled and subsequently transported through the condensate outlet pipe to a transfer vessel for filtration.
[0012] As a further optimization of this utility model, high-temperature condensate flows by gravity to the condensate collection tank through an inclined condensate collection pipe. The inclined design utilizes gravity to accelerate the water flow and prevent condensate from stagnating.
[0013] As a further optimization of this utility model, the other end of the transfer vessel is connected to a diversion pipe assembly, which consists of multiple sets of pipes, each of which is controlled by an independent pump.
[0014] A further specific technical solution involves collecting the filtered condensate in a transfer dish and distributing it to multiple water supply units via a distribution pipeline assembly at the other end, thus achieving condensate recycling. Each pipeline is controlled by an independent pump, which can adjust the flow rate and pressure according to the water supply needs of different areas to achieve precise water supply.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model features a heat exchanger connected to the outside of the collection tank. The heat exchanger performs heat exchange operations, using the high temperature of the high-temperature condensate to heat the water flow outside the loop. The heated water is then discharged from the circulating water outlet pipe, achieving efficient heat transfer. The heat exchanger maximizes waste heat recovery, significantly improving energy utilization efficiency.
[0017] 2. This utility model's condensate filtration mechanism uses a motor-driven eccentric wheel structure to drive a moving plate and purification head in reciprocating motion, achieving dynamic filtration of condensate. The purification head adopts a composite structure of "stainless steel frame + activated carbon particles." The stainless steel frame intercepts particulate impurities such as rust and sediment, while the activated carbon particles adsorb soluble pollutants such as organic matter and oil. Combined with the slight oscillation of the transverse moving frame, it enhances self-cleaning ability, prevents filter clogging, and effectively avoids scaling in heating pipes and corrosion of equipment.
[0018] 3. This utility model utilizes a diversion pipeline assembly at the rear of the transfer vessel, controlled by an independent pump. This allows for real-time adjustment of flow rate and pressure based on the water supply needs of different areas, achieving on-demand distribution of condensate and preventing energy waste. This design is adaptable to diverse heating scenarios, enhancing system operational flexibility and accuracy while reducing pipeline load and extending the overall equipment lifespan.

The motion plate 55 drives the purification head 510 to reciprocate synchronously through the connecting plate 59;
[0039] The motion frame 551 at the bottom of the motion plate 55 is hinged to the receiving frame 511 via the connecting shaft 512. The other end of the receiving frame 511 is hinged to the transverse moving frame 514 via the deflection shaft 513. The transverse moving frame 514 can slide laterally within the transverse sliding groove 515, causing the purification head 510 to swing slightly laterally during the filtration process for transverse purification.

[0040] Working principle of condensate recovery heating device
[0041] I. Condensate Collection and Preliminary Heat Recovery
[0042] Condensate collection process: High-temperature condensate flows by gravity through the inclined condensate collection pipe 1 to the condensate collection tank 2. The inclined design utilizes gravity to accelerate the water flow and prevent condensate stagnation. A heat exchanger 31 is connected to the outside of the collection tank 2. The heat exchanger 31 performs heat exchange operations. The high-temperature condensate enters the loop inside the heat exchanger 31, and the water from the hot water circulation tank 33 enters the heat exchanger 31. The high temperature of the high-temperature condensate heats the water outside the loop, and the heated water is then discharged from the circulating water outlet pipe 35, achieving efficient heat transfer. The treated condensate has a lower temperature and is subsequently transported to the transfer dish 4 through the condensate outlet pipe 34 for filtration.
[0043] II. Drive and Impurity Interception of Condensate Filtration Mechanism
[0044] Filter mechanism powered by:
[0045] The motor 52 is fixed to the mounting base 51. Its output end drives the drive disk 53 to rotate. The hinged shaft 54 reciprocates with the rotation of the drive disk 53, thereby pushing the motion plate 55 to make linear reciprocating motion within the limit frame 56.
[0046] The limiting groove 57 on the surface of the motion plate 55 slides in conjunction with the limiting post 58 on the limiting frame 56 to ensure that the motion plate slides smoothly along a fixed trajectory and avoids deviation. The motion plate 55 drives the purification head 510 to reciprocate synchronously through the connecting plate 59;
[0047] The motion frame 551 at the bottom of the motion plate 55 is hinged to the receiving frame 511 via the connecting shaft 512. The other end of the receiving frame 511 is hinged to the transverse moving frame 514 via the deflection shaft 513. The transverse moving frame 514 can slide laterally within the transverse sliding groove 515, causing the purification head 510 to oscillate slightly laterally during the filtration process for transverse purification; the condensate is also agitated at the same time, improving the purification efficiency.
[0048] The purification head 510 adopts a composite structure of "stainless steel frame + activated carbon particles". The activated carbon particles adsorb soluble pollutants such as organic matter, oil stains, and heavy metal ions to achieve multi-stage purification. The purification head 510 travels back and forth in the transfer dish 4 to continuously filter the flowing condensate water and prevent impurities from accumulating and clogging the pipes.
