Description

TECHNICAL FIELD

[0001] The utility model relates to liquid nanofiltration equipment technical field especially relates to a high accuracy liquid nanofiltration equipment. BACKGROUND

[0002] In many industrial fields, such as electronic chip manufacturing, pharmaceutical, chemical industry, there is a very high requirement for the purity of liquid used in the production process. For example, in electronic chip manufacturing, ultra-pure water is needed to clean and etch the surface of the chip. If there are trace amounts of impurity ions, organic matter or microorganisms in the water, it may cause short circuit, performance degradation or even scrap of the chip. According to statistics, the concentration of nano-particles and ions in the water must be controlled at a very low level during the chip manufacturing process, such as the impurity content in each liter of water should be less than one microgram. In the pharmaceutical industry, the purity of raw material liquid and cleaning liquid in the production process is also strictly required. Because impurities may affect the quality, efficacy and even safety of the drug, therefore, the development of industrial production urgently needs high-precision liquid nanofiltration equipment to meet the demand for high-purity liquid.

[0003] Currently, the liquid nanofiltration equipment on the market is mainly composed of core filtration components and power transmission components. Traditional liquid filtration equipment, such as sand filtration and general filtration membrane, has a larger filtration pore size, generally in the micron level, which is difficult to effectively intercept nano-level pollutants. Sand filtration mainly filters liquid through the pores between particles, and has poor filtering effect on impurities with a particle size less than one micron, and cannot remove nano-level heavy metal ions and organic molecules. Although the pore size of general filtration membrane can reach sub-micron level, its filtering efficiency for nano-level pollutants is still low. This makes the traditional filtration equipment unable to meet the requirements of industrial production and drinking water purification for high-precision filtration, resulting in a large amount of impurities in the treated liquid, affecting product quality and human health. At the same time, the traditional filtration equipment often lacks selective filtration ability for different substances. In the filtration process, it cannot retain beneficial ingredients and remove harmful impurities according to actual needs. In drinking water purification, the traditional filtration equipment may remove beneficial mineral ions in water while removing impurities, resulting in water that is too pure, affecting taste and human health. In industrial production, for some liquid treatment that needs to retain specific ingredients, the traditional filtration equipment cannot achieve selective filtration, increasing the difficulty and cost of subsequent treatment.
