Description

Technical Field

[0001] This application relates to the field of condensate recovery technology, and more specifically, to a condensate recovery device. Background Technology

[0002] In steam systems, after steam completes tasks such as heating and doing work, it will condense into water due to heat dissipation. This condensate contains a large amount of heat energy, and its water quality is usually good, which has high recycling value. Therefore, condensate recovery devices have emerged to achieve the effective recovery and reuse of condensate, so as to save water resources and improve energy efficiency.

[0003] The recovery tank is an important piece of equipment in the recovery system, used to store the recovered condensate. Since the rate at which the steam equipment discharges condensate is closely related to the equipment's operating status, and the recovery tank can only store a limited amount of water, if the water level in the recovery tank is too high and the water is not drained in time, the entire recovery system will not be able to continue to work normally. This will result in the inability to recover the condensate generated later, causing a waste of energy and water resources. At the same time, the condensate often carries some impurities during the recovery process, such as rust, dirt, and suspended solids. If these impurities enter the recovery tank, they will not only reduce the quality of the condensate, but may also cause wear and blockage to other equipment during subsequent use. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a condensate recovery device, which aims to improve the problem that when the water level in the recovery tank is too high and the water is not drained in time, the entire recovery system will not be able to continue to work normally, resulting in the inability to recover the condensate generated later, causing a waste of energy and water resources.

[0005] This application provides a condensate recovery device, including a main unit and a filtration structure. The main unit includes a recovery tank, a water supply component, a drainage component, and a heat exchange component. There are two recovery tanks. The water supply component is located above the recovery tank, the drainage component is located on the front of the recovery tank, and the heat exchange component is located inside the recovery tank. The filtration structure includes a filter box, a cover plate, a filter plate, and a housing. The filter box is located on the surface of the water supply component. The cover plate is detachably connected to the top of the filter box, the filter plate is fixedly connected to the bottom of the cover plate, and the housing is fixedly connected to the back of the filter plate.

[0006] In one specific implementation, the water conveying assembly includes a first conveying pipe, a second conveying pipe, a tee pipe, and a third conveying pipe. The first conveying pipe is located above the recovery tank, the second conveying pipe is located in front of the first conveying pipe, the tee pipe is fixedly connected to the bottom of the second conveying pipe, the third conveying pipe is fixedly connected to both sides of the tee pipe, and the bottom of the third conveying pipe is fixedly connected to the top of the recovery tank.

[0007] In the above process, the first conveying pipe, the second conveying pipe, the tee pipe and the third conveying pipe work together to convey the condensate to the two recovery tanks.

[0008] In one specific implementation, the water supply assembly further includes a drain valve and an electrically controlled valve. The drain valve is located between the first and second supply pipes and is fixedly connected to one end of both pipes. The electrically controlled valve is disposed on the surface of the third supply pipe.

[0009] In the above process, the steam trap can automatically remove condensate, air and other non-condensable gases from the steam, while preventing steam leakage, and the electrically controlled valve can control the flow direction of the condensate.

[0010] In one specific implementation, the recovery tank is equipped with a liquid level sensor and a microcontroller. The output of the liquid level sensor is connected to the output of the microcontroller, and the output of the microcontroller is connected to the output of the electrically controlled valve.

[0011] In the above implementation process, the liquid level sensor is used to monitor the water level in the recovery tank in real time. If the water level is too high and is not drained in time, the liquid level sensor can transmit the monitoring data to the microcontroller through an electrical signal. The microcontroller controls two electrically controlled valves to close the electrically controlled valve above the full recovery tank and open the electrically controlled valve above the other recovery tank, so that the other recovery tank can perform the storage work of condensate recovery, thereby ensuring that the condensate can be fully recovered.

[0012] In one specific implementation, the drainage assembly includes a discharge pipe and a valve, the discharge pipe being fixedly connected to the front of the recovery tank, and the valve being disposed on the surface of the discharge pipe.

[0013] In the above process, the discharge pipe is used to discharge the condensate recovered in the recovery tank, and the valve is used to control the flow rate of the discharge pipe.

[0014] In one specific implementation, the heat exchange assembly includes a heat exchange tube and a support plate. The heat exchange tube is located inside the recovery tank, with its output and input ends extending to the outside of the recovery tank. The support plate is located on the surface of the heat exchange tube, and its back side is fixedly connected to the inner wall of the recovery tank.

[0015] In the above process, the support plate is used to support the heat exchange tube and improve its stability. The heat exchange tube is used to transport water. When the water flows through the inside of the recovery tank, it can come into contact with the high-temperature condensate and play a role in heat exchange, thereby improving the heat utilization rate.

[0016] In one specific implementation, support plates are fixedly connected to both sides of the filter box, and detachable plates are fixedly connected to both sides of the cover plate. Magnets are provided in the inner cavities of the support plates and detachable plates and are magnetically connected. A sealing gasket is provided at the junction of the filter box and the cover plate.

[0017] In the above process, the support plate, the picking plate, and the magnet inside them work together to position the cover plate, improving its stability, and the sealing gasket prevents steam leakage.

[0018] In one specific implementation, the inner cavity of the filter plate is provided with a filter screen for filtering impurities in the condensate.

[0019] In the above process, the filter screen is used to filter impurities in the condensate, allowing it to be stored in the box for cleaning.

[0020] In one specific implementation, a limiting frame is fixedly connected to the inner cavity of the filter box, the filter plate is detachably connected to the inner cavity of the limiting frame, and a baffle for filling gaps is fixedly connected to the back of the limiting frame.

[0021] In the above process, the limiting frame is used to support and guide the filter plate, and the baffle is used to fill the gap between the box and the inner wall of the filter box to ensure that the condensate is fully filtered.

[0022] In one specific implementation, the rear end of the first conveying pipe is connected to the condensate pipe of the steam equipment, and the two ends of the heat exchange pipe are respectively connected to an external water supply pipe and a drain pipe.

[0023] In the above process, the first conveying pipe connects the steam equipment and the recovery equipment, and the heat exchange pipe is used to convey water. When the water flows through the inside of the recovery tank, it can come into contact with the high-temperature condensate and play a role in heat exchange, thereby improving the heat utilization rate.

[0024] Compared with the prior art, the beneficial effects of this application are as follows: both recovery tanks can be used to store cooling water. When one recovery tank is full and not drained in time, the flow direction of the cooling water can be automatically adjusted by the sensor so that the other recovery tank can recover the cooling water. During the recovery of condensate, the filter structure can filter out impurities in the water and remove impurities to prevent them from entering the recovery tank. Attached Figure Description
