Description

Technical Field

[0001] This utility model relates to the field of circulating water equipment technology, specifically to an electro-deionization device for cleaning scale in circulating water. Background Technology

[0002] In industrial production, circulating water systems are widely used in cooling, heating and other processes. However, hardness ions such as calcium and magnesium in circulating water can easily form scale on the surface of pipes and equipment, leading to decreased heat transfer efficiency, increased energy consumption, and even equipment damage. Traditional chemical descaling methods have problems such as high chemical costs and environmental pollution. Electrostatic desalination technology is a water treatment method that uses an electric field and ion exchange membrane to remove ions from water. The equipment mainly consists of an electrolytic cell, electrode plates, ion exchange membranes, and compartments. It uses a DC electric field to drive cations and anions in the water to migrate to the cathode and anode, respectively. The selective permeability of the cation exchange membrane and anion exchange membrane separates the ions into the concentrate chamber for discharge, thereby purifying the water. The box-type electrolytic cell is divided into open-type and closed-type electrolytic cells. Open-type electrolytic cells are convenient for heat dissipation and observation of electrolysis, but they are susceptible to pollution or corrosion from the external environment. Closed-type electrolytic cells can improve electrical performance such as electrolysis efficiency and current density, but they have poor heat dissipation performance. Existing electrolytic cells cannot simultaneously meet the requirements of convenient heat dissipation, observation of electrolysis, and reduction of external environmental pollution and corrosion. Utility Model Content

[0003] The purpose of this invention is to provide an electro-deionization device for cleaning scale in circulating water, so as to solve the problem that existing electrolytic cells cannot simultaneously meet the requirements of easy heat dissipation, observation of electrolysis, and reduction of external environmental pollution and corrosion.

[0004] To achieve the above objectives, the basic solution provided by this utility model is as follows: an electrolytic desalination device for cleaning scale in circulating water, comprising an electrolytic cell, an inlet pipe and an outlet pipe on the electrolytic cell, a flow meter on the inlet pipe and a water quality analyzer on the outlet pipe, a cover plate hinged to the electrolytic cell, padlocks and buckles on the electrolytic cell and the cover plate, a plurality of cation and anion membranes arranged alternately inside the electrolytic cell, the cation and anion membranes dividing the electrolytic cell into a plurality of concentrate chambers and desalination chambers, electrode plates at both ends inside the electrolytic cell, an adjustment component for adjusting the spacing between the electrode plates on each electrode plate, and a rinsing component for cleaning scale on the electrode plates on the electrolytic cell.

[0005] The principle and beneficial effects of this utility model are as follows: During use, the flow meter can detect the flow rate of circulating water in real time, thereby controlling the flow rate; the water quality tester can detect the water hardness of the outlet pipe in real time, thereby adjusting the electrolytic cell; circulating water enters the electrolytic cell through the inlet pipe; after being purified by electrolysis in the electrolytic cell, the circulating water flows out from the outlet; when it is necessary to observe the electrolysis, open the padlock latch, rotate the cover plate, and observe the electrolysis in the electrolytic cell; at the same time, it can also dissipate heat from the electrolytic cell; after observing the electrolytic cell and dissipating heat, rotate the cover plate and then use the padlock latch to close the electrolytic cell, which can reduce the pollution and corrosion of the electrolytic cell by the external environment.

[0006] Option 2, a preferred option of the basic option, includes a stepper motor whose lead screw moves through the electrolytic cell and is fixed to the electrode plate. In use, the distance between the two electrode plates is adjusted by the water hardness on the water quality tester to increase electrolysis efficiency.

[0007] Option 3, a preferred option of the basic option, includes a flushing assembly consisting of a drain pipe and a settling tank. The electrolytic cell and the settling tank are connected via the drain pipe. A backwash pipe is fixed to the settling tank and is equipped with a water pump. The backwash pipe is connected to the inlet pipe, and a three-way valve is installed at the connection between the backwash pipe and the inlet pipe. When the electrolytic cell is descaled periodically, the electrolytic cell is first stopped, and then the three-way valve is used to connect the backwash pipe and the inlet pipe. The water pump is then started to reuse the clear liquid in the settling tank to clean the electrolytic cell.

[0008] Option 4, which is the preferred option of Option 3, is to install ultrasonic generators at both ends of the electrolytic cell. Each time the electrolytic cell is descaled periodically, the electrolytic cell is first stopped, and then the ultrasonic generator is started to clean the scale. Then, the cell is rinsed with the flushing assembly.

[0009] Option 5, which is the preferred option of the basic option, is that the electrolytic cell is equipped with a protective net; when observing the electrolysis in the electrolytic cell, the protective net can increase the safety of the operators.

[0010] Option 6, which is the preferred option of the basic option, has a gradient porous structure for the electrode plate, and the surface of the electrode plate is coated with a nano-catalytic layer. The gradient porous structure can increase the surface area of ​​the electrode, making it easier for the electrolyte to penetrate into the electrode and reducing polarization. The nano-catalytic layer can enhance the corrosion resistance of the electrode plate, protect the electrode plate, and thus extend the service life of the electrode plate.
