Description

Technical Field

[0001] This utility model belongs to the field of boiler water treatment technology, specifically relating to a boiler water desalination treatment device. Background Technology

[0002] Boiler water desalination is a crucial step in water treatment in industrial production, typically occurring during the boiler feedwater treatment stage and serving as a pre-operation stage of the boiler system. Its purpose is to remove dissolved salts (such as calcium, magnesium, sodium, and chloride ions) from the water, preventing boiler scaling and corrosion, and improving steam quality. The high-salinity wastewater generated during desalination (such as reverse osmosis concentrate and ion exchange regeneration wastewater) can be reduced in volume and recycled through evaporation.

[0003] Chinese patent document CN222159808U discloses a water treatment device for boiler water desalination. It features a hook rod that rotates a horizontal bar around a long axis during lifting, and multiple evaporator frames supported by springs and guided by vertical rods. This allows wastewater to fill each evaporator frame sequentially from top to bottom. The hook rod descends synchronously with the lowest evaporator frame as it becomes heavier due to the added water, causing a turntable connected to the long axis to rotate. This misaligns the supply pipe and the bend, allowing the turntable to block the supply pipe and halt wastewater injection. This ensures each evaporator frame receives sufficient wastewater and prevents a decrease in treatment efficiency due to continuous wastewater injection.

[0004] However, in the existing technology, as the evaporation process proceeds, the salts that accumulate in the evaporator frame not only easily form scale on the frame, making it heavier and thus affecting the injection of wastewater and increasing the heat transfer resistance, but also block the wastewater flow channels between the frames. Therefore, a boiler water desalination treatment device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a treatment device for desalination of boiler water.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A boiler water desalination treatment device includes a treatment component that can continuously evaporate and treat high-salinity wastewater generated during desalination. The treatment component is equipped with a material guiding component that can inject wastewater into the device and discharge it along different paths. An observation component is provided in front of the treatment component to make it easy to observe and sample the liquid level inside the device.

[0008] The treatment components include a rotating component that can contact wastewater over a large area and rapidly heat and evaporate it, a loading component that can hold the wastewater and provide a mounting base for the rotating component, and a scraping component that can prevent scale buildup on the surface of the rotating component.

[0009] A drive component that enables the rotating part to rotate continuously is provided on one side of the processing component;

[0010] The loading components include processing tanks;

[0011] The rotating component includes a heated tank disposed within the processing tank;

[0012] The scraping component includes a ring frame fixedly connected to the processing tank, multiple support rods fixedly connected below the ring frame, a cover fixedly connected to the lower end of the support rods, a telescopic rod between the support rods and the cover, a spring between the support rods and the telescopic rods, and a U-shaped scraper fixedly connected between the telescopic rods in the same longitudinal position.

[0013] Preferably, the loading component also includes shaft seats that are fixedly installed on both sides of the processing tank, and a hollow shaft that passes through the center of the shaft seat is movably installed.

[0014] Preferably, a heating tank is fixedly connected between the two hollow shafts.

[0015] Preferably, the rotating component also includes a spiral baffle plate fixedly connected to the inner side of the hot tank, and extension tubes are fixedly connected to both sides of the hot tank, with a rotatable joint fixedly connected to the end of the extension tube away from the hot tank.

[0016] Preferably, the bearing seat is rotatably connected to the hollow shaft, and the hollow shaft is connected to the hot tank via a flange.

[0017] Preferably, the bearing seat, hollow shaft, and extension tube are coaxial, and the outer diameter of the extension tube is smaller than the inner diameter of the hollow shaft.

[0018] Preferably, both the support rod and the cover are slidably connected to the telescopic rod.

[0019] The beneficial effects of this utility model are as follows: By setting a U-shaped scraper on the outside of the hot tank that can closely abut its outer surface, the hot tank, which can continuously rotate inside the treatment tank and heat the wastewater to evaporate it, can be continuously scraped by the U-shaped scraper, which is also set inside the treatment tank and whose movable range is limited by components such as support rods, so as to prevent scale from forming on the surface of the hot tank, thereby effectively reducing the adverse effects of scale on the evaporation treatment of this equipment.

[0032] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0033] like Figures 1-7 As shown, a boiler water desalination treatment device includes a treatment component 1 that can continuously evaporate and treat high-salinity wastewater generated during desalination. The treatment component 1 is equipped with a material guiding component 2 that can inject wastewater into the device and discharge it along different paths. An observation component 3 is provided in front of the treatment component 1 to make it easy to observe and sample the liquid level in the device.

[0034] In this embodiment: the processing component 1 includes a rotating component that can contact wastewater over a large area and rapidly heat and evaporate it, a loading component that can hold wastewater and provide a mounting base for the rotating component, and a scraping component that can prevent scale buildup on the surface of the rotating component.

[0035] The loading component includes a processing tank 101, the rotating component includes a hot tank 104 disposed inside the processing tank 101, and the scraping component includes a ring frame 108 fixedly connected to the processing tank 101. Multiple support rods 109 are fixedly connected below the ring frame 108, and a cover 110 is fixedly connected to the lower end of each support rod 109. A telescopic rod 111 is provided between the support rod 109 and the cover 110, and a spring 112 is provided between the support rod 109 and the telescopic rod 111. The telescopic rods 111, which are longitudinally aligned, are fixedly connected. The loading component includes a U-shaped scraper 113 and bearings 102 fixedly installed on both sides of the processing tank 101. A hollow shaft 103 is movably installed at the center of the bearing 102 and passes through it. A hot tank 104 is fixedly connected between the two hollow shafts 103. The rotating component also includes a spiral baffle 105 fixedly connected to the inner side of the hot tank 104. Extension tubes 106 are fixedly connected to both sides of the hot tank 104. A rotatable joint 107 is fixedly connected to the end of the extension tube 106 away from the hot tank 104.

[0036] The bearing seat 102 is rotatably connected to the hollow shaft 103. The hollow shaft 103 is connected to the hot tank 104 through a flange. The bearing seat 102, the hollow shaft 103, and the extension tube 106 are coaxial, and the outer diameter of the extension tube 106 is smaller than the inner diameter of the hollow shaft 103. The support rod 109 and the cover 110 are slidably connected to the telescopic rod 111.

[0037] The treatment tank 101 provides mounting positions for components such as the shaft seat 102, injection valve 201, top cover 202, and level cylinder 301, and also accommodates components such as the hot tank 104, ensuring that wastewater can be evaporated after being injected into the treatment tank 101. Two hollow shafts 103 are mounted on both sides of the treatment tank 101 with their axes aligned via the shaft seat 102, allowing the hollow shafts 103 to penetrate the side wall of the treatment tank 101 and rotate. An extension pipe 106 that passes through the hollow shafts 103 allows the heating medium to be injected from the outside into the hollow hot tank 104, which is connected to the hollow shafts 103. A rotatable joint 107 replaces the component that rotates with the hot tank 104. The extension pipe 106 is connected to an external heat medium circulation device. The spiral baffle 105 slows down the flow speed of the heat medium in the hot tank 104, so that the hot tank 104 can be heated and maintained rapidly under the action of the heat medium. The support rod 109 is installed through the ring frame 108. The lower end of the support rod 109 is partially closed by the cover 110. The support rod 109, the cover 110, and the spring 112 together limit the movable range of the telescopic rod 111 connected to the U-shaped scraper 113, and make the telescopic rod 111 tend to push the U-shaped scraper 113 towards the hot tank 104. The U-shaped scraper 113 can be rotated in the hot tank 104 to fully scrape its surface.

[0038] In this embodiment: the material guiding assembly 2 includes an injection valve 201 fixedly connected to the rear of the processing tank 101, an upper cover 202 fixedly connected above the ring frame 108, a lower cover 203 fixedly connected below the processing tank 101, and a discharge valve 204 fixedly connected below the lower cover 203.

[0039] The liquid inlet channel of this equipment is controlled by the liquid injection valve 201. The upper cover 202 and the lower cover 203 respectively seal the openings at the top and bottom of the treatment tank 101. The upper cover 202 can discharge the steam formed by the evaporation of wastewater. The lower cover 203 can be used to hold or discharge wastewater in the treatment tank 101. The discharge valve 204 can control the opening and closing of the discharge channel of the lower cover 203.

[0040] In this embodiment: the observation component 3 includes a liquid level cylinder 301 fixedly connected to the front of the processing tank 101, a one-way valve 302 fixedly installed above the liquid level cylinder 301, and a sampling valve 303 fixedly connected below the liquid level cylinder 301.

[0041] The liquid level cylinder 301, which has two different heights connected to the treatment tank 101, displays the liquid level in the treatment tank 101. The one-way valve 302 allows operators to easily inject chemicals into the liquid level cylinder 301, enabling the chemicals to mix with the wastewater in the treatment tank 101. This further achieves the purposes of preventing scaling, adjusting pH, suppressing foam, and optimizing crystallization. The sampling valve 303 allows operators to easily remove a small amount of wastewater from the treatment tank 101 for testing to monitor the concentration of key ions in the wastewater, thereby predicting the risk of scaling and optimizing the dosage and operating parameters.

[0042] In this embodiment: A drive assembly 4 that enables the rotating component to rotate continuously is provided on one side of the processing assembly 1. The drive assembly 4 includes a frame 401 fixedly connected to the outer side of the processing tank 101. A motor 402 is fixedly installed on one side of the frame 401. A first pulley 403 is fixedly connected to the output end of the motor 402. A second pulley 404 is fixedly connected to the hollow shaft 103 adjacent to the motor 402. A belt 405 is provided between the first pulley 403 and the second pulley 404.

[0043] The center line of the output end of the motor 402 is parallel to the axis of the hollow shaft 103. The motor 402 is installed through the frame 401. The rotation of the output end of the motor 402 is transmitted to the hollow shaft 103 connected to the second pulley 404 through the first pulley 403, the belt 405, and the second pulley 404, so that the hollow shaft 103 can drive the hot tank 104 and another hollow shaft 103 to rotate.

[0044] Working principle: When this equipment is installed for treating wastewater generated from boiler water desalination, the two rotatable joints 107 are connected to the inlet and outlet of an external heat medium circulation device, respectively, so that the heat medium can circulate along an independent channel to continuously heat the hot tank 104. The injection valve 201 is connected to an external wastewater injection device, so that wastewater can enter the equipment at the required speed. The top cover 202 is connected to an external condensation device, so that the water evaporated in the equipment can be reused or deeply purified after discharge. The discharge valve 204 is connected to an external collection container, so that the high-concentration wastewater after evaporation can be collected for purification and resource utilization or compliant disposal. The one-way valve 302 is connected to an external dosing device for appropriate dosing, further improving the stability and efficiency of the equipment operation.

[0045] Once preparations are complete, wastewater can be injected into the equipment at a certain speed through the injection valve 201, provided the temperature of the hot tank 104 exceeds the boiling point of the wastewater. During injection, the liquid level can be observed through the level cylinder 301. To ensure evaporation efficiency, the liquid level should be maintained at a height that allows the hot tank 104 to be touched but not submerged. As the water in the wastewater evaporates upon contact with the hot tank 104, to prevent scaling on the surface of the hot tank 104 in contact with the wastewater, the motor 402 can be used to drive the hot tank 104 to rotate. Because the telescopic rod 111, under the action of the spring 112, can push the U-shaped scraper 113 tightly against the hot tank 104, the solid components such as salt precipitated from the wastewater will be scraped off by the U-shaped scraper 113 during the continuous rotation of the hot tank 104, thus significantly reducing the impact of scaling on the wastewater evaporation treatment in this equipment. High-concentration wastewater remaining in the equipment can be quickly discharged after the discharge valve 204 is opened.

[0046] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
