Description

Technical Field

[0001] This utility model relates to the field of energy conservation and environmental protection, and in particular to a steam condensate cooling and recycling device for air conditioning water humidification. Background Technology

[0002] In current production technologies, steam is widely used as an important energy source in various fields. However, steam generates a large amount of condensate during use. Only a portion of this condensate is used as makeup water for hot water systems, while the majority is usually discharged directly, resulting in energy waste and water loss.

[0003] In air conditioning systems, ultrasonic water humidifiers require purified water as their source, placing high demands on water quality and temperature. If condensate water were reused as a water source for ultrasonic water humidifiers, it would be entirely possible to recycle and reuse it. However, current condensate water recycling methods primarily rely on simple cooling and filtration. On one hand, traditional cooling methods struggle to lower the condensate water temperature to a suitable range, failing to meet the optimal inlet temperature requirements for ultrasonic water humidification. On the other hand, simple filtration methods cannot effectively remove impurities, harmful substances, and odors from the condensate water, resulting in substandard water quality. After all, using poor-quality water sources easily leads to the accumulation of bacteria and minerals. Furthermore, if the water tank is not cleaned regularly, bacteria and microorganisms will proliferate. These bacteria and microorganisms are carried out with the water mist, and long-term inhalation can cause harm to the body. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model incorporates a heat exchanger and a physical filter in its structure. The heat exchanger uses forced convection and natural heat dissipation for heat exchange, which can achieve efficient cooling of condensate water temperature. The physical filter ensures that the water quality meets the pure water standard, ultimately achieving efficient cooling, purification, and reuse of steam condensate water, thus realizing the efficient utilization of condensate water.

[0005] To achieve the above objectives, one or more embodiments of the present invention provide the following technical solutions: A steam condensate cooling and recycling device for air conditioning water humidification includes a steam condensate collection tank, a heat exchanger, a physical filter, and an air conditioning ultrasonic water humidification device. The inlet of the steam condensate collection tank is provided with a steam condensate recovery pipe. The outlet of the steam condensate collection tank is connected to the heat exchanger via a first water pump and a first pipeline. The end of the heat exchanger away from the steam condensate collection tank is connected to a water tank via a second pipeline. The other end of the water tank is connected to the physical filter via a second water pump and a third pipeline. The end of the physical filter away from the water tank is connected to the air conditioning ultrasonic water humidification device via a fourth pipeline.

[0006] Furthermore, a first temperature sensor is installed in the first pipeline, and a second temperature sensor is installed in the third pipeline.

[0007] Furthermore, pressure sensors are also installed in the first and third pipelines.

[0008] Furthermore, a third temperature sensor is installed in the second pipeline near the heat exchanger outlet.

[0009] Furthermore, both the first and third pipelines are equipped with electric regulating valves.

[0010] Furthermore, it also includes a PLC control box, which is electrically connected to the first temperature sensor, the second temperature sensor, the third temperature sensor, and the pressure sensor, respectively. The PLC control box is also electrically connected to the electric regulating valve, the first water pump, and the second water pump that connect to each pipeline.

[0011] Furthermore, the heat exchanger is a fresh air conditioning heat exchanger.

[0012] Furthermore, a liquid level sensor is installed inside the water tank, and the liquid level sensor is electrically connected to the PLC control box.

[0013] Furthermore, the physical filter employs a multi-layer filter structure.

[0014] Furthermore, the water pump is a multi-stage centrifugal pump.

[0015] Compared with the prior art, this utility model has at least the following advantages and beneficial effects: 1. When high-temperature steam condensate is delivered to the heat exchanger, the forced convection and natural heat dissipation of the heat exchanger can be used to ensure that the condensate temperature is stable within a suitable temperature range, meeting the optimal inlet water temperature requirements for ultrasonic water humidification.

[0016] 2. The condensate stored in the water tank and cooled down is filtered through a physical filter to remove impurities, harmful substances and odors from the condensate, ensuring that the water quality meets the pure water standard and extending the service life of the humidification equipment.

[0017] 3. The PLC controller of this utility model can monitor the temperature and pressure of condensate in real time through corresponding temperature and pressure sensors, and transmit the data to the PLC controller. The PLC controller controls the flow rate and pressure of condensate through electric regulating valves and water pumps according to the set temperature and pressure values, so as to ensure the stability and reliability of system operation.

[0021] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention.

[0022] Where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0023] Example 1: like Figure 1 As shown, this embodiment provides a steam condensate cooling and recycling device for air conditioning water humidification, including a steam condensate collection tank 1, a heat exchanger 2, a physical filter 7, and an air conditioning ultrasonic water humidification device 3. The inlet of the steam condensate collection tank is provided with a steam condensate recovery pipe 4. The outlet of the steam condensate collection tank is connected to the heat exchanger 2 via a first water pump 5 and a first pipe 6. The end of the heat exchanger 2 away from the steam condensate collection tank 1 is connected to a water tank 9 via a second pipe 8. The other end of the water tank is connected to the physical filter via a second water pump 10 and a third pipe 11. The end of the physical filter 7 away from the water tank is connected to the air conditioning ultrasonic water humidification device via a fourth pipe.

[0024] In this embodiment, both the first water pump 5 and the second water pump 10 are multi-stage centrifugal pumps. The first water pump is used to transport the condensate in the collection tank to the heat exchanger, and the second water pump is used to transport the purified water in the water tank to the physical filter.

[0025] The steam condensate collection tank 1 is welded from 304 stainless steel, and the inner wall is treated with anti-corrosion to prevent rust caused by long-term storage of condensate. In addition, to prevent condensate diversion at the inlet of the steam condensate recovery pipe, a check valve can be installed at the inlet of the recovery pipe. In order to meet the inlet water temperature requirements of the ultrasonic humidification equipment, that is, to ensure that the condensate temperature is stable at 40±2℃, the heat exchanger 2 adopts a fresh air air conditioning heat exchanger. This heat exchanger uses forced convection and natural heat dissipation for heat exchange, using the fresh air of the air conditioning system as the cooling medium. The cooling medium and the condensate exchange heat in the heat exchanger, reducing the condensate temperature to 40±2℃.

[0026] High-temperature steam condensate is collected in steam condensate collection tank 1 through steam condensate recovery pipe 4, and then transported to heat exchanger 2 for cooling through first pipeline 6 by first water pump 5. After entering the heat exchanger, the fresh air conditioning heat exchanger uses forced convection and natural heat dissipation to exchange heat with the high-temperature condensate, thereby ensuring that the condensate temperature is stable at 40±2℃, which meets the optimal inlet water temperature requirements of ultrasonic water humidification.

[0027] The condensate after heat exchange will enter the water tank 9 through the second pipeline 8 for storage. In order to ensure that the condensate stored in the water tank is not polluted by changes in the surrounding environment, the water tank 9 in this embodiment is made of stainless steel. The stainless steel water tank has good corrosion resistance and sealing performance, which can ensure that the water quality is not polluted. In addition, a liquid level sensor 12 is also installed inside the water tank to monitor the water level in the tank in real time. When the water level is lower than a certain value, water can be added by the first water pump 5. Once the water level reaches a certain critical value, the second water pump is started, and the water is delivered to the air conditioning ultrasonic water humidification equipment through the corresponding pipeline.

[0028] Considering that the existing steam condensate itself does not meet the water quality standards, and that the condensate liquid contains impurities, harmful substances, and odors, the physical filter 7 in this embodiment adopts a multi-layer filter structure. For example, the physical filter can adopt a three-layer filter structure. The first layer can be a 50-mesh stainless steel filter to remove particulate impurities with a diameter >0.3mm, such as rust and silt. The second layer can be a 100-mesh nylon filter to remove suspended solids with a diameter >0.15mm. The third layer can be an activated carbon filter to adsorb organic impurities and odors. The specific number of filter layers and the type of filter in each layer of the physical filter in this embodiment can be selected according to the actual situation. It is sufficient to effectively remove particulate impurities, suspended solids, and odors by using the above-mentioned multi-layer filtration structure.

[0029] When the condensate level in the water tank reaches a certain critical value or when the air conditioning ultrasonic water humidifier has a water supply demand, the second water pump starts, and the condensate in the water tank is transported to the physical filter 7 through the third pipeline 11. The multi-layer filter screen in the physical filter removes particulate impurities, suspended solids, and odors. The condensate purified by the physical filter is then transported to the air conditioning ultrasonic water humidifier 3 through the fourth pipeline 13, thereby meeting the pure water demand of the air conditioning ultrasonic water humidifier. In this embodiment, the filtration effect of the physical filter can effectively remove impurities, harmful substances, and odors from the condensate, ensuring that the water quality meets the pure water standard and extending the service life of the humidifier.

[0030] To better ensure the stability, reliability, and controllability of the above process, this embodiment includes a first temperature sensor 14 in the first pipeline, a second temperature sensor 15 in the third pipeline 11, pressure sensors 16 in both the first and third pipelines 11, a third temperature sensor 17 at the heat exchanger outlet, and electric regulating valves 18 on both the first and third pipelines 11. Furthermore, this embodiment includes a PLC control box 19, which is electrically connected to the first, second, third, and pressure sensors, and also electrically connected to the electric regulating valves, the first water pump, and the second water pump connected to each pipeline.

[0031] The PLC control box 19 acts as the monitoring and control system for the entire process. It monitors the temperature and pressure data of the condensate in real time through corresponding temperature and pressure sensors. The PLC controller compares the acquired temperature and pressure data with the set temperature and pressure values ​​and takes appropriate measures based on the comparison results. It controls the flow and pressure of the condensate through electric regulating valves and water pumps to ensure the stability and reliability of the system operation.

[0032] For example, when the temperature detection value is greater than the set temperature range value, the condensate temperature after cooling will be reduced by increasing the fresh air volume of the heat exchanger (increasing the amount of cooling medium) and reducing the opening of the electric regulating valve of the first pipeline (reducing the flow rate and extending the heat exchange time) until the temperature value of the second temperature sensor meets the optimal inlet water temperature requirement of ultrasonic water humidification.

[0033] When the pressure value of the pressure sensor exceeds the set pressure value, the PLC controller sends an alarm signal and automatically closes the electric regulating valve of the corresponding pipeline to prevent overpressure in the pipeline; when the water level in the water tank is less than the set liquid capacity value, the second water pump will be started to replenish water; when the water level is greater than the maximum limit value, the second water pump will be shut off.

[0034] In addition, when the condensate flow rate of the fresh air conditioning system is zero, the system can be interlocked to start and stop, ensuring the safe operation of the system.

[0035] This embodiment achieves efficient water resource recovery and stable operation of the air conditioning humidification system through the above-mentioned cooling, purification, and automated control of steam condensate, demonstrating significant water and energy saving benefits and promotional value.

[0036] The workflow of the entire system described above is as follows: Industrial steam condensate enters a steam condensate collection tank for temporary storage via a steam condensate recovery pipeline. The condensate in the collection tank is then pumped by a first water pump and transported to a heat exchanger via a first pipeline. The condensate is cooled in the heat exchanger, and a second temperature sensor at the heat exchanger outlet monitors the cooled water temperature. The cooled condensate is then transported to a water tank for storage via a second pipeline. When the condensate level in the water tank reaches a certain critical value or when the air conditioning ultrasonic water humidification equipment requires water supply, the steam condensate stored in the water tank is pumped by a third water pump and a third pipeline to a physical filter. The physical filter uses a multi-layer filter structure to perform preliminary filtration of the condensate, removing physical impurities. The water filtered by the physical filter is then transported to the air conditioning ultrasonic water humidification equipment via a fourth pipeline for air conditioning humidification operations.

[0037] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
