Description

A medical condensate recovery and utilization device Technical Field

[0001] This invention relates to the field of heat recovery system technology, and in particular to a medical condensate recovery and utilization device. Background Technology

[0002] In hospitals and similar facilities, common equipment includes pressure steam sterilizers and medical water treatment systems. The condensate produced by pressure steam sterilizers is free of organic matter and meets emission standards. However, the current problems are: 1. The condensate from pressure steam sterilizers has a certain temperature, and direct discharge wastes water resources and heat energy; 2. The RO membrane water production rate of medical water treatment equipment decreases as the water temperature drops. Under the same pressure, a 1°C decrease in temperature reduces water production by 2%-4%, especially in winter when the inlet water temperature is low, severely impacting membrane water production. Therefore, a device is needed to solve these problems. Summary of the Invention

[0003] To address the above needs, this invention provides a medical condensate recovery and utilization device that effectively utilizes thermal energy, solves the problem of low inlet water temperature in medical equipment affecting membrane water production, is simple to operate, highly automated, reduces energy consumption, and saves water resources.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A medical condensate recycling device includes a sterilizer, a medical RO water treatment system, and a condensate reuse system. The condensate reuse system includes a main condensate pipe with ball valve A connected to the sterilizer outlet, a main tap water pipe with ball valve B, a medical equipment inlet pipe with a proportional regulating valve and ball valve D connected to the medical RO water treatment equipment inlet, and a water tank with a jacket. The outer wall of the water tank is spirally wound with flexible tubing. A condensate inlet pipe with electric valve A and a condensate inlet pipe with electric valve B are connected between the main condensate pipe and the water tank. Second, the condensate inlet pipe connects to the bottom inlet of the flexible hose, and the top outlet of the flexible hose and the second condensate inlet pipe connect to the top of the water tank. An electric valve D is installed on the main water supply line located before the ball valve B. A water supply inlet pipe with an electric valve E connects the main water supply line before the electric valve D to the interlayer inlet of the water tank. A water supply outlet pipe connects the main water supply line behind the electric valve D to the interlayer outlet of the water tank. The medical equipment inlet pipe connects to the bottom of the water tank, and the main water supply line connects to the proportional regulating valve. The interlayer maximizes the contact area between the tap water and the internal condensate, removing heat from the condensate. The flexible hose wall thickness is <1.5mm to improve heat dissipation. The condensate outlet temperature of the sterilizer is around 40℃, while the tap water temperature is around 25℃ in summer and around 5℃ in winter. The temperature of the inlet water to the medical RO water treatment equipment is controlled by adjusting the pipeline and the proportional regulating valve.

[0006] Preferably, the main condensate drain lines before and after ball valve A are connected to a condensate bypass line equipped with an electric valve C. When the condensate level in the tank reaches the high level, electric valves A and B close, and electric valve C opens.

[0007] Preferably, the water tank is provided with an overflow port at the top, which is connected to the main condensate line or condensate bypass line via a condensate overflow pipe. When the condensate in the water tank overflows from the overflow port, the condensate enters the main condensate line through the condensate overflow pipe.

[0008] Preferably, a check valve A is provided on the condensate overflow pipe.

[0009] Preferably, a check valve B is provided on the tap water outlet pipe, and a check valve D is provided on the medical equipment inlet pipe between the water tank and the proportional regulating valve.

[0010] Preferably, a check valve C and a ball valve C are sequentially installed on the main water supply line behind the ball valve B, and a branch water supply pipe is connected between the main water supply line of the ball valve B and the check valve C to other water supply points.

[0011] Preferably, the medical device's water inlet pipe is equipped with a temperature sensor. The ratio of tap water to condensate is dynamically adjusted based on the outlet water temperature detected by the temperature sensor.

[0012] Preferably, the water tank is equipped with a level measuring device. This device measures the level of condensate in the water tank. The water tank has high, medium, and low level indicators. When the condensate level in the water tank reaches the high level, the addition of condensate stops.

[0013] Preferably, the water tank is made of 304 stainless steel and has a built-in immersion ultraviolet sterilizer to prevent the growth of microorganisms. The width of the interlayer is 40mm to 60mm, the length of the hose is 300m to 400m, and the diameter is 15mm to 20mm.

[0014] Preferably, the condensate reuse system further includes a heat exchanger. An RO (recycled oxygen) pipeline connects the sterilizer inlet and the medical RO water treatment equipment outlet. The condensate inlet pipe connects to the heat exchanger's inlet and outlet, and the RO pipeline connects to the heat exchanger's inlet and outlet. The heat exchanger can be a plate heat exchanger. The RO water serves as the sterilizer's feed water. The high-temperature condensate and low-temperature RO water exchange heat in the heat exchanger. The increased temperature of the RO water effectively raises the feed water temperature, saving energy consumed in heating the sterilizer.

[0015] Preferably, a balancer and a check valve E are installed on the RO permeate pipeline between the heat exchanger and the sterilizer. To ensure that there is always water flowing in the RO permeate pipeline from the outlet of the medical RO water treatment equipment to the inlet of the sterilizer, a balancer is added before the sterilizer. When the sterilizer is not in the water intake state or when the number of sterilizers used is small and the water consumption is low, the RO permeate after passing through the heat exchanger is first stored in the balancer. When the sterilizer is re-intaken, the water stored in the balancer is used preferentially.

[0016] Preferably, the balancer has a built-in immersion ultraviolet sterilizer to prevent the growth of microorganisms.

[0017] Preferably, the condensate recycling system consists of one or more sets. The number of sterilizers used varies depending on the size of the hospital. One set of condensate recycling systems is sufficient for 5 or fewer sterilizers; two sets can be used for 5 to 10 sterilizers; three sets are used for 10 to 15 sterilizers, and so on.

[0018] The advantages of this invention are: 1. It effectively utilizes thermal energy, solving the problem of low inlet water temperature in medical equipment affecting membrane water production; it is simple to operate, highly automated, reduces energy consumption, and saves water resources; 2. It features a modular design, allowing for flexible combination and use according to the hospital's water consumption; 3. The water tank has an internal layer and a flexible hose wrapped around its outer wall, improving heat exchange efficiency and saving floor space and cost. Attached Figure Description

[0031] To more clearly illustrate the present invention, the invention will be further described below with reference to the accompanying drawings.

[0032] Example 1: As shown in Figures 1-2, a medical condensate recycling device includes a sterilizer 10, a medical RO water treatment device 20, and a condensate recycling system. The condensate recycling system includes a condensate main pipeline 100 connected to the outlet of the sterilizer 10 and equipped with a ball valve A101, a tap water main pipeline 200 connected to the inlet of the medical RO water treatment device 20 and equipped with a ball valve B201, a medical device inlet pipeline 300 equipped with a proportional regulating valve 301 and a ball valve D302, and a water tank 400 with a jacket 401. The outer wall of the water tank 400 is spirally wound with a flexible hose 402. A condensate inlet pipe with an electric valve A102 and a condensate inlet pipe with an electric valve B103 are connected between the condensate main pipeline 100 and the water tank 400. The condensate inlet pipe is connected to the bottom inlet of the flexible hose 402, and the top outlet of the flexible hose 402 and the condensate inlet pipe 2 are connected to the top of the water tank 400. An electric valve D202 is installed on the main water supply line 200 located in front of the ball valve B201. A water inlet pipe with an electric valve E203 is connected between the main water supply line 200 in front of the electric valve D202 and the water inlet of the interlayer 401 of the water tank 400. A water outlet pipe is connected between the main water supply line 200 behind the electric valve D202 and the water outlet of the interlayer 401 of the water tank 400. The medical equipment inlet pipe 300 is connected to the bottom of the water tank 400, and the main water supply line 200 is connected to the proportional regulating valve 301.

[0033] The medical equipment water inlet pipe 300 is equipped with a temperature sensor, and the water tank 400 is equipped with a liquid level measuring device 403.

[0034] In addition, the water tank 400 is made of 304 stainless steel and has a built-in immersion ultraviolet sterilizer. The width of the interlayer 401 is 40mm to 60mm, and the length of the hose 402 is 300m to 400m, with a diameter of 15mm to 20mm.

[0035] Example 2: As shown in Figure 1, based on Example 1, the condensate main pipeline 100 before and after the ball valve A101 is connected to a condensate bypass with an electric valve C104. The water tank 400 is provided with an overflow port at the top, which is connected to the condensate main pipeline 100 or the condensate bypass through a condensate overflow pipe.

[0036] The condensate overflow pipe is equipped with a check valve A105, the tap water outlet pipe is equipped with a check valve B204, and the medical equipment inlet pipe 300 between the water tank 400 and the proportional regulating valve 301 is equipped with a check valve D303.

[0037] Among them, a check valve C205 and a ball valve C206 are sequentially installed on the main water supply line 200 behind the ball valve B201, and a branch water supply pipe is connected between the main water supply line 200 and the ball valve B201 and the check valve C205.

[0038] The condensate recycling control logic for Examples 1 and 2 is as follows:

[0039] 1. In summer, the tap water temperature is around 25℃. Water resources are saved by neutralizing the tap water and condensate. Ball valve A101 is normally closed, ball valves B201, C206, and D302 are normally open, electric valves A102 and E203 are open, and electric valves B103, C104, and D202 are closed. Condensate at around 40℃ enters the water tank 400 through the flexible hose 402 wrapped around the outer wall of the condensate inlet pipe. Tap water enters the interlayer 401 from the top of the water tank 400 through the tap water inlet pipe and flows out from the tap water outlet pipe at the bottom of the water tank 400. The tap water is constantly flowing, carrying away heat from the condensate in the water tank 400. The proportional regulating valve 301 controls the flow ratio of tap water to condensate to be greater than or equal to 2, thus ensuring that the mixed water temperature is below 30℃, suitable for use as inlet water for medical equipment.

[0040] When the condensate in water tank 400 reaches the high level, electric valve C104 opens and electric valve A102 closes.

[0041] When the condensate in the water tank 400 exceeds the overflow port and overflows, it directly enters the condensate main pipe 100.

[0042] 2. In winter, the tap water temperature is around 5℃. Ball valve A101 is normally closed, while ball valves B201, C206, and D302 are normally open. Electric valves B103 and D202 are open, while electric valves A102, E203, and C104 are closed. Condensate at around 40℃ enters the water tank 400 directly through the condensate inlet pipe 2. Tap water does not pass through the water tank 400. Through the proportional regulating valve 301, the flow ratio of tap water to condensate is controlled to be less than or equal to 1. The heat energy of the condensate is used to solve the problem of low inlet water temperature for medical equipment and reduced RO membrane water production, while saving water resources.

[0043] When the condensate in the water tank 400 reaches the high level, the electric valve C104 opens and the electric valve B103 closes. When the condensate in the water tank 400 exceeds the overflow port, it overflows and directly enters the condensate main pipeline 100.

[0044] Example 3: As shown in Figure 3, based on Example 1 or Example 2, the condensate recycling system further includes a heat exchanger 30. An RO water production pipeline 500 is connected between the inlet of the sterilizer 10 and the outlet of the medical RO water treatment equipment 20. The condensate inlet pipe 1 is connected to the inlet 1 and outlet 1 of the heat exchanger 30, and the RO water production pipeline 500 is connected to the inlet 2 and outlet 2 of the heat exchanger 30.

[0045] The RO water pipeline 500 between the heat exchanger 30 and the sterilizer 10 is equipped with a balancer 501 and a check valve E502. The balancer 501 has a built-in immersion ultraviolet sterilizer.

[0046] The condensate recycling control logic in Example 3 is as follows:

[0047] Based on the condensate reuse control logic of Embodiment 1 and Embodiment 2, the high-temperature condensate in the condensate inlet pipe 1 and the low-temperature R0 product water in the R0 product water pipe 500 exchange heat in the heat exchanger 30. The heated R0 product water is equivalent to increasing the inlet water temperature of the heat exchanger 30, which can save the energy consumed by the sterilizer 10 in heating up.

[0048] In Example 3, the number of condensate recycling systems is one set, which is suitable for hospitals with 5 or fewer sterilizers 10.

[0049] Example 4: As shown in Figure 4, the difference from Example 3 is that the number of condensate recycling systems is two, which is suitable for hospitals with more than 5 but less than 10 sterilizers 10.

[0050] Example 5: As shown in Figure 5, the difference from Example 3 and Example 4 is that the number of condensate recycling systems is three, which is suitable for hospitals with more than 10 but less than 15 sterilizers.

[0051] The above description is only a specific embodiment of the present invention, but the structural features of the present invention are not limited thereto. The present invention can be used in similar products. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
