This invention discloses a water-cooled circulation device for wind turbine generators with internal scale-cleaning function. The invention relates to the field of wind power generation technology and includes a frame. A housing is fixedly installed on the top of the frame, and a rotating shaft is rotatably installed at the center of one side of the outer surface of the housing. An inner cover is fixedly installed inside the housing. This water-cooled circulation device for wind turbine generators with internal scale-cleaning function works by mixing coolant and a descaling agent. The descaling agent treats the scale formed on the inner wall of the cavity, dissolving it through a reaction. Then, a water pump installed outside the housing draws the coolant. During coolant extraction, a cleaning component rotates inside the housing due to the suction force of the pump, rubbing against the inner wall of the housing to clean the drainage area and prevent dead zones during coolant extraction. This also prevents impurities from the coolant reacting with scale from settling inside the housing.

The present application relates to the technical field of scale removal, and discloses a scale removal device for electric kettle, which comprises a base, a supporting rod is slidably connected to the inner wall of the top of the base, a clamping device is arranged on the inner wall of the supporting rod, a cleaning device is arranged on the top of the base, a pushing device is arranged on the surface of the cleaning device, and a blocking device is arranged on the surface of the cleaning device. The phosphoric acid descaling agent can be sprayed out of the through hole on the surface of the pressing valve and used for descaling and softening the scale on the inner wall of the kettle, which facilitates the subsequent scraping of the scale, reduces the shaking of the kettle during scale removal, improves the stability of the kettle and the scraping effect of the scale inside the kettle, the clamping plate is gathered and used for clamping and fixing the kettle, the stability of the kettle during scale removal is further improved, and the operator does not need to manually press the limit, so that the safety of the device is improved.

This utility model discloses a dual-purpose (dry and wet) heat exchange tube, belonging to the field of heat exchange technology. It includes a flat heat exchange tube with straight-through S-shaped fins connected to it. A partition plate is fixed inside the flat heat exchange tube, and a baffle plate is installed inside the tube. A connecting assembly is installed at the end of the tube, and a support and protective structure is snapped onto it. Using a flat heat exchange tube in conjunction with straight-through S-shaped fins achieves both dry and wet application, reducing equipment size. The straight-through S-shaped fins have low resistance, are easy to clean with cold water, have no dead corners, and are not prone to scaling. Even if scaling occurs, it can be thoroughly removed by using a descaling agent and high-pressure water rinsing without damaging the fins. The partition plate and baffle plate inside the flat heat exchange tube can change the flow state, increase turbulence, and thus improve heat exchange efficiency. The support and protective structure provides support for the flat heat exchange tube.

This invention provides a descaling system and cleaning method for plate heat exchangers used with non-purified calcium-type brine, belonging to the field of plate heat exchanger cleaning technology. The descaling device specifically includes a plate heat exchanger assembly, a flow channel switching assembly, an online cleaning assembly, a storage and filling assembly, and an intelligent control center. The flow channel switching assembly is used to switch the main flow of brine between the first and second heat exchange flow channel units. The online cleaning assembly is used to perform online cleaning of the isolated heat exchange flow channel units through both physical flushing and chemical dissolution. The storage and filling assembly is used to store and fill the system with raw brine, heat exchange medium, cleaning fluid, and composite high-efficiency descaling agent. This system realizes non-disassembly online cleaning of the calcium sulfate scale layer on the plate heat exchanger during the preheating process of non-purified calcium-type raw brine, overcoming the defects of traditional manual disassembly, soaking, and brushing methods, such as high labor intensity, harsh working environment, and low efficiency.

This utility model discloses a scale-resistant solar water heater, including a support frame, a drive motor, and a cleaning assembly. Starting the drive motor rotates gear one, which in turn drives gear two to rotate synchronously. Gear two meshes with an annular toothed plate, and the position of the annular toothed plate is fixed, causing gear two to rotate along the circumference of the annular toothed plate while rotating itself. The rotation of gear two drives a rotating rod, which in turn drives a cleaning brush. The bristles of the cleaning brush make close contact with the inner wall of the water storage tank, allowing the cleaning brush to clean the scale on the inner wall of the water storage tank. Descaling agent is added to the storage tank through the inlet pipe. Starting the bidirectional water pump allows the descaling agent inside the storage tank to enter the interior of the water storage tank through transport pipes two and one. The descaling agent soaks the scale on the inner wall of the water storage tank, dissolving stubborn scale and making it easier for the cleaning brush to remove it.
