Abstract
Description
Technical Field
[0001] This utility model relates to the field of pure water supply equipment, specifically to a pure water supply device. Background Technology
[0002] Pure water is widely used in medical institutions and laboratories, especially in medical institutions. Medical purified water must meet strict standards such as conductivity and total bacterial count, for example, conductivity <1.0μs / cm, to ensure water quality safety. Currently, the pure water supply system in medical institutions generally includes a pure water storage tank, which is connected to the pure water production equipment and then to multiple water points through supply pipelines. Pure water storage tanks are generally not sealed, making them prone to the introduction of air impurities. After prolonged use, the conductivity of the pure water storage tank may not meet the usage requirements, and the water points are not always open. If left unused for a long time, bacteria can easily grow at the water outlet, and the bacterial film formed by these bacteria can clog the water equipment pipelines, seriously affecting the quality of the pure water supply. Utility Model Content
[0003] To address the problems existing in the prior art, this utility model provides an EDI pure water supply device with a reasonable structural design that effectively solves the problems of pure water pollution and bacterial growth.
[0004] To achieve the above-mentioned objectives, the technical solution of this utility model is as follows:
[0005] An EDI pure water supply device includes a reverse osmosis water machine, a pure water storage tank, an EDI module, a circulating water pipeline, and a water point. The reverse osmosis water machine is connected to the pure water storage tank through an inlet pipe. A booster pump is connected to the outlet of the pure water storage tank to provide power to the circulating water pipeline. The outlet of the booster pump is connected to the EDI module. The water outlet of the EDI module is connected in series with the water point on the circulating water pipeline. The outlet of the circulating water pipeline is connected to the pure water storage tank.
[0006] Furthermore, the outlet of the booster pump is connected to a bacterial filter, and the outlet of the bacterial filter is connected to the EDI module.
[0007] Furthermore, the booster pump is in a normally open state, which can ensure that the water in the circulating water pipeline is in a continuous flow state; the booster pump is a variable frequency pump, and its outlet is equipped with a pressure sensor to control the power output according to the water pressure changes in the circulating water pipeline.
[0008] Furthermore, the outlet of the circulating water pipe extends below the liquid surface of the pure water storage tank, reducing contact with air in the pure water storage tank and lowering the probability of soluble gases dissolving into the pure water.
[0009] Furthermore, the pure water storage tank is equipped with an ultraviolet disinfection lamp and a level gauge.
[0010] Furthermore, it also includes a controller, which is connected to the circuitry of the level gauge, reverse osmosis water machine, EDI module, booster pump, and ultraviolet germicidal lamp.
[0011] The EDI module can be the RE series secondary EDI module of Tianjin Ruichun brand. Its inlet is connected to the outlet of the booster pump, its concentrate outlet discharges wastewater, and its product water outlet is connected to the circulating water pipeline.
[0012] Furthermore, the booster pumps are two connected in parallel, one normally open and one on standby.
[0013] Furthermore, the EDI module is connected in parallel with a bypass, which is equipped with a solenoid valve, so that water can be supplied via the bypass when the EDI module fails.
[0014] This utility model has the following beneficial effects:
[0015] This invention optimizes and improves the pure water supply pipeline, changing the simple water supply pipeline into a circulating water pipeline. The EDI module has a strong ion exchange capacity, which can effectively remove ionic impurities in the water and improve water purity. The outlet of the EDI module is directly connected in series with the point of use, so that the high-purity water does not come into contact with air when it reaches the point of use, ensuring the purity of the water at the point of use. At the same time, combined with the circulating water pipeline design, a continuous circulation supply of pure water is achieved, avoiding the growth of bacteria due to water stagnation. In addition, the filter can further intercept any microorganisms that may be present, ensuring that the output water quality is safe and reliable, and meeting the needs of high-purity water applications.
