Description

Technical Field

[0001] The utility model discloses a water purification device, in particular to an ultrasonic water purification device. Background Art

[0002] Heat exchangers generally have different degrees of fouling problems. Since fouling is a poor conductor of heat, it increases the heat transfer resistance of the heat exchange process between the fluid and the heat exchange wall, increases the flow resistance, and reduces the heat exchange performance of the heat exchange equipment. In addition, the deposition of fouling on the heat exchange surface will cause local overheating and lead to a decrease in mechanical properties. In severe cases, it will cause corrosion of equipment and pipeline walls, resulting in a large amount of economic losses. Therefore, it is necessary to conduct in-depth theoretical and applied research on scale inhibition technology to minimize the impact of fouling on heat exchange equipment, which has great practical significance for promoting energy conservation and emission reduction in my country, improving energy utilization and developing a green circular economy.

[0003] Physical scale inhibition mainly refers to the use of sound, light, electricity, magnetism and other technologies to change the motion state of ions and molecules in hard water, so as to achieve the effect of scale inhibition. This equipment uses ultrasonic treatment technology to achieve scale inhibition effect. It is easy to use, low cost and pollution-free, so it has broad application prospects. Ultrasonic anti-scaling technology mainly uses ultrasonic strong sound field to treat fluid to inhibit the generation of large particles of dirt and peel off the scale deposited on the wall. Many studies have shown that the ultrasonic cavitation effect plays a major role in the scale inhibition effect. The so-called ultrasonic cavitation effect refers to a series of dynamic processes of cavitation bubbles. When high-intensity ultrasonic waves pass through the liquid, cavitation bubbles are generated when the sound wave is negative pressure, and the cavitation bubbles collapse when the sound wave is positive pressure. The process of cavitation bubble collapse is accompanied by high temperature and high pressure, and is accompanied by the generation of strong shock waves and powerful microjets. The cavitation process is also accompanied by many chain effects. For example, the shear force formed by the shear effect acts on the scale layer, making it loose and difficult to adhere to the pipe wall and form a scale layer. The activation effect occurs along with the cavitation effect, generating hydroxyl free radicals, which further generate hydrogen peroxide, thereby improving the scale-dissolving ability of the liquid, promoting the precipitation of scale-causing components in hard water and suspending them in the water, and further separating the precipitated crystals from the water, thereby achieving the purpose of reducing water hardness.

[0004] The installation of trapezoidal fins in the pipeline changes the path and flow state of the water flow, thereby enhancing the disturbance of the water. The protrusions of the fins and the protruding cones of the amplitude rod are arranged in an alternating manner, so that the direction of the flow channel is constantly changed, increasing the friction between the fluid and the fins, which will also cause the fluid to produce more turbulence and vortices, thereby enhancing the disturbance of the water, so that the fluid continuously washes the ultrasonic amplitude rod. The stepped amplitude rod can use the refraction effect of the cone slope on the ultrasonic wave to enhance the sound intensity of the radially propagated ultrasonic wave, thereby increasing the intensity of the ultrasonic wave on the water, fully promoting the precipitation of calcium ions, and thus achieving the purpose of water purification. The ultrasonic treatment section is divided into three parts. The first section is used as a pretreatment unit, which is mainly responsible for the preliminary purification of the raw water, removing large particles and suspended matter, reducing turbidity, and preventing the subsequent treatment unit from being blocked. The second part is used as the main treatment unit, which uses the cavitation effect and mechanical vibration of the ultrasonic wave to quickly precipitate calcium and magnesium ions in the water, so that the calcium and magnesium salts are condensed, precipitated or separated. The post-treatment unit is mainly responsible for further improving the water quality, removing residual substances, and improving the quality of water. The three parts adjust the ultrasonic power according to the actual situation of the water and work together to achieve the purpose of purifying water quality. Summary of the invention

Under the drainage and disturbance of the ribs, the water flow will fully contact with the amplitude rod, thereby enhancing the effect of the ultrasonic wave and greatly enhancing the water purification effect of the equipment.

[0013] In the above ultrasonic generating device, the sedimentation section is provided with a first sewage pipe, a second sewage pipe and a third sewage pipe, and is provided with a second solenoid valve, a third solenoid valve and a fourth solenoid valve respectively.
