Description

Technical Field

[0001] This utility model relates to the field of water treatment, specifically to a water softening device for power plants. Background Technology

[0002] The quality of water used in power plants directly affects the operating efficiency and lifespan of equipment. Calcium and magnesium ions in hard water easily form scale inside equipment, leading to reduced heat exchange efficiency and pipe blockage. Therefore, designing an efficient water softening device is crucial for power plants.

[0003] Currently, power plants typically use semi-permeable membranes to retain calcium and magnesium ions, resulting in effluent water hardness close to 0. These membranes can simultaneously remove multiple impurities such as heavy metals and organic matter, and require no downtime for regeneration, enabling continuous 24-hour water production. This makes them suitable for power plants with a high degree of automation.

[0004] However, the above method results in a significant decrease in water production when the water temperature is below 15°C, requiring a heating device and increasing energy consumption. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a water softening device for power plants, which aims to solve the problem that the current use of semi-permeable membranes in power plants to retain calcium and magnesium ions requires water temperatures above 15°C, necessitating the installation of heating devices and increasing energy consumption.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a water softening device for power plant water, which uses resin to adsorb calcium and magnesium ions, the water softening device for power plant water includes a tank, a drainage mechanism and a reduction mechanism disposed in the tank;

[0009] In summary, the power plant water softening device proposed in this utility model introduces raw water into a tank, and a moving mechanism facilitates the rapid adsorption of calcium and magnesium ions by the resin. After softening, the adsorption capacity of the resin can be reduced using brine, again accelerated by the moving mechanism, and the brine is discharged.

[0029] Please participate Figures 1-5 The diagram shows a structural schematic of a water softening device for power plants provided in one embodiment of this utility model. The device uses resin to adsorb calcium and magnesium ions. The water softening device includes a tank, a drainage mechanism 200 disposed within the tank 100, and a reduction mechanism 300, wherein:

[0030] To support the tank 100, a supporting ring is provided at the bottom of the tank 100, and three supporting feet are provided between the supporting ring and the bottom of the tank 100 to facilitate the installation of a second drain pipe 500 at the bottom of the tank 100 for discharging cleaning wastewater. The tank 100 is also provided with a water inlet 120 for supplying raw water to the tank 100. A cylindrical screen 110 is provided inside the tank 100, and resin is contained within the cylindrical screen 110. When raw water is supplied to the tank 100 through the water inlet 120, the resin adsorbs calcium and magnesium ions in the raw water, thereby softening the raw water.

[0031] To discharge the resin-treated water, a drainage mechanism 200 includes a first drain pipe 210 mounted on a tank 100 and a water pump 220 located at one end of the first drain pipe 210, with the water pump 220 positioned outside the tank 100. One end of the first drain pipe 210 is located at the bottom of the tank 100, and a filter screen is also provided at the bottom end of the first drain pipe 210 to remove larger diameter impurities from the raw water, improving water purity. The water pump 220 is located at the end of the first drain pipe 210 furthest from the filter screen. After the raw water enters the tank 100 and is softened by the resin, the softened water is drawn out from the first drain pipe 210 by the water pump 220 for further processing.

[0032] As the resin adsorbs calcium and magnesium ions, its adsorption capacity decreases. To ensure the softening of the raw water, brine can be added to the tank 100 to restore the resin's adsorption capacity. The reduction mechanism 300 includes a feeding assembly 310 and a cleaning assembly 320 disposed on the tank 100. The feeding assembly 310 is used to add a reducing agent to the tank 100. In this embodiment, the reducing agent can be brine.

[0033] Furthermore, the feeding assembly 310 includes a feeding hopper 311 disposed on the tank body 100, and a first valve 312 disposed at the connection between the feeding hopper 311 and the tank body 100. The feeding hopper 311 contains a reducing agent, that is, the feeding hopper 311 is used to hold salt. The opening and closing of the feeding hopper 311 is controlled by the first valve 312, thereby reducing the adsorption capacity of the resin.

[0034] Furthermore, the cleaning assembly 320 includes a water-filling bracket 321 mounted on the tank 100, and a plurality of water-guiding rings 322 equidistantly stacked on the water-filling bracket 321, the water-guiding rings 322 being fitted around the outer periphery of the cylindrical screen 110. A plurality of nozzles 323 are evenly arranged inside any one of the water-guiding rings 322. The water inlet of the water-filling bracket 321 penetrates the tank 100 and is used to connect a water pipe. Before the first valve 312 is opened to add salt to the tank 100, the water-filling bracket 321 adds water to the tank 100. It is worth noting that the water added to the tank 100 by the water-filling bracket 321 is treated water. When the water delivered by the water-filling bracket 321 reaches the expected value, the first valve 312 is opened to add salt to the tank 100, dissolving it into brine to restore the resin's adsorption capacity. After the resin is restored, the second valve 510 is opened, and the wastewater generated after restoration is discharged through the second drain pipe 500 below.

[0035] It is important to emphasize that, in order to improve the rate at which the resin adsorbs calcium and magnesium ions, and the adsorption capacity of the resin reduced by brine, a moving mechanism 400 located within the tank 100 can be used to accelerate the liquid flow within the tank 100, thereby accelerating the adsorption and reduction rates. The moving mechanism 400 includes a cylinder 410, a transmission rod 420 mounted on the cylinder 410, and a moving member 430 located at the end of the transmission rod 420 away from the cylinder 410, the moving member 430 being located inside the cylindrical screen 110. The cylinder 410 drives the transmission rod 420 to move the moving member 430 up and down around the center of the tank 100. By accelerating the liquid flow, the reaction rate of the resin with raw water and brine is increased, thereby increasing the rate at which the resin absorbs calcium and magnesium ions and the rate at which the resin is reduced.

[0036] In summary, the power plant water softening device proposed in this utility model introduces raw water into a tank, and a moving mechanism facilitates the rapid adsorption of calcium and magnesium ions by the resin. After softening, the adsorption capacity of the resin can be reduced using brine, again accelerated by the moving mechanism, and the brine is discharged. The softening is achieved through resin adsorption, and the use of brine to reduce the resin's adsorption capacity eliminates the need for heating, saving energy. Specifically, the drainage mechanism includes a first drain pipe fixed to the tank and a water pump located at one end of the first drain pipe, with the pump positioned outside the tank. A cylindrical screen is installed inside the tank, containing resin. A moving mechanism on the tank drives the flow of raw water to ensure full contact with the resin, and a reduction mechanism adds salt to the tank to further reduce the resin's adsorption capacity.
