Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a circulating water treatment device. Background Technology

[0002] Circulating water systems are one of the essential energy media in the metallurgical industry. Improving the utilization rate of circulating water will greatly alleviate water pressure. However, reducing the discharge of circulating water and increasing the concentration ratio will inevitably lead to problems such as scaling, corrosion, and the proliferation of microorganisms in pipes and equipment.

[0003] Currently, for industrial circulating water treatment systems, in order to reduce the adverse effects on equipment and pipelines caused by the concentration of salts and other pollutants in the circulating water, the common method is to add chemical agents to maintain water quality stability and increase the concentration ratio of the circulating water system. However, this method has certain drawbacks, including expensive chemicals, high operating costs, and the environmental pollution caused by phosphorus in the system's wastewater. Utility Model Content

[0004] The purpose of this invention is to provide a circulating water treatment device that, by adopting an electrochemical circulating water treatment method, eliminates the need for chemical agents, thereby reducing water treatment costs. It also has excellent functions of scale prevention and removal, sterilization and algae elimination, and corrosion inhibition, thus improving the water treatment effect and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a circulating water treatment device, comprising a filter barrel, an electrolyzer, an alkaline water tank, a water pump 1, an acidic water tank, and a water pump 2. The filter barrel has an inlet 1 at the top and an outlet 1 at the upper right side, with the inlet 1 connected to a wastewater inlet pipe. The electrolyzer has an inlet 2 on the left side and an alkaline water outlet and an acidic water outlet on the front, with the inlet 2 connected to the outlet 1 via a connecting pipe 1. The alkaline water tank and the acidic water tank each have an inlet 3 at the top, with the two inlets 3 connected to the alkaline water outlet and the acidic water outlet respectively via connecting pipe 2. The lower left side of the alkaline water tank and the lower right side of the acidic water tank each have an outlet 2.

[0006] Preferably, the filter bucket has a filter screen installed inside and a diversion channel installed on top. The filter screen is located below the water outlet, and the outlet of the diversion channel extends below the filter screen. By setting the outlet of the diversion channel to extend below the filter screen, impurities in the wastewater are filtered and permanently retained below the filter screen.

[0007] Preferably, the filter bucket has a drain outlet in the middle of its bottom, and a drain valve is installed on the drain outlet. By providing the drain outlet, it is easy to open the drain valve to discharge the impurities that have settled inside the filter bucket.

[0008] Preferably, the alkaline water tank is divided into two water storage areas by a partition. A second drain outlet is provided at the lower right side of the alkaline water tank, and a second drain valve is installed on the second drain outlet. By providing the second drain outlet, it is possible to easily open the second drain valve to discharge the scale that has settled in the alkaline water tank.

[0009] Preferably, the inlet end of the water pump is connected to the outlet end of the alkaline water tank via an inlet pipe, and the outlet end is connected to an external water storage source via an outlet pipe. By setting up the water pump, water in the alkaline water tank can be drawn out and recycled.

[0010] Preferably, the inlet end of the second water pump is connected to the outlet end of the acidic water tank via the second inlet pipe, and the outlet end is connected to an external water storage source via the second outlet pipe. By setting up the second water pump, water in the acidic water tank can be drawn out and recycled.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In use, this invention involves filtering cooling wastewater through an inlet pipe into a filter tank. The filtered water then enters an electrolyzer through a connecting pipe. The electrolyzer electrolyzes the filtered water, producing acidic water that flows out through an acidic water outlet, passes through a connecting pipe, and enters an acidic water tank. A second water pump then draws out the acidic water and sends it directly to an external water storage source for reuse. Alkaline water flows out through an alkaline water outlet, passes through a connecting pipe, and enters the right half of the alkaline water tank's storage area. After sedimentation and scale removal in the right half of the alkaline water tank, the water enters the left half of the storage area. Then, a second water pump draws out the alkaline water and sends it to an external water storage source for reuse. This electrochemical circulating water treatment method eliminates the need for chemical additives, reducing water treatment costs. It also provides excellent scale prevention and removal, sterilization and algae control, and corrosion inhibition, thus improving water treatment efficiency. Attached Figure Description
