Technical Field

[0001] This invention relates to the field of water technology, specifically a negative pressure coagulation and purification method. Background Technology

[0002] Water is an inorganic compound composed of hydrogen and oxygen. It is non-toxic and drinkable. At room temperature and pressure, it is a colorless, odorless, and transparent liquid. Known as the source of life, it is a vital substance for sustaining life. Also called hydrogen peroxide, water is one of the most abundant substances on Earth, covering approximately 71% of the Earth's surface. It is a crucial resource for all life, including inorganic compounds and humans, and a vital component of living organisms. Although present in small amounts in the air, it is an essential component of the atmosphere.

[0003] To improve drinking water safety, laboratory research requires high-purity water, industrial production needs purified water as a raw material or coolant, the pharmaceutical and biotechnology fields require strictly purified water, and the electronics industry needs ultra-high-purity water to ensure device performance and reliability, water purification is necessary. The purpose of water purification is to ensure that the purity of the water meets specific usage requirements and standards to meet the needs of various fields. However, existing water treatment methods may not be able to effectively remove trace pollutants and chemicals, such as heavy metal ions and organic pollutants, resulting in water quality that cannot meet higher standards. At the same time, some existing purification methods also pose certain environmental pressures in terms of energy consumption and waste treatment. For higher water quality requirements, traditional water purification technologies may need to be improved and perfected.

[0004] Therefore, those skilled in the art have provided a negative pressure coagulation purification method to solve the problems mentioned in the background art. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a negative pressure coagulation purification method, the purification method comprising the following steps:

[0006] S1 Pretreatment: Removes suspended solids, microorganisms and other large particulate impurities from the water. First, a coarse filter is used for primary filtration. Then, the filtered water is introduced into a disinfection tank and ultraviolet light is used to disinfect organisms and pathogens in the water.

[0007] S2 Temperature and Pressure Regulation: The water is heated to the target temperature using a heat exchanger, and the system pressure is adjusted to a negative pressure state lower than atmospheric pressure using pumps and valves to regulate the treated water to the temperature and pressure conditions suitable for negative pressure condensation and purification.

[0008] S3 negative pressure coagulation: Water is introduced into the reactor and a coagulant is added to accelerate the coagulation reaction and form aggregates. Negative pressure is applied to promote evaporation and assist in the formation and separation of solids from water. In a negative pressure environment, the conversion of coagulable components is promoted, thereby separating them from water.

[0009] S4 Separation and Collection: The condensed liquid and solid are completely separated and collected separately. A centrifuge is used to collect the evaporated condensate as a pure product.

[0010] S5 Heat Recovery: Uses a heat exchanger to recover the heat generated during the process, in order to save energy and improve efficiency. A heat pump is used to reintroduce the heat released from condensation and evaporation into the system.

[0011] S6 post-treatment: Ensures that the obtained pure water meets relevant standards. If necessary, it can be further purified through processes such as carbon filtration, ion exchange, and reverse osmosis.

[0012] Preferably, the coarse filter used in step S1 is a multi-layer woven fabric filter screen with a mesh size of 100-150 mesh.

[0013] Preferably, the output power of the ultraviolet sterilizer in step S1 is 10W-30W, and the sterilization time is 2min-5min.

[0014] Preferably, the heating temperature in step S2 is between 40°C and 90°C, and the pressure range is from -0.02 MPa to -0.08 MPa.

[0015] Preferably, the centrifugal force of the centrifuge in step S4 is 1000g-2000g, and the separation time is 5min-10min.

[0016] Compared with the prior art, the present invention provides a negative pressure coagulation purification method, which has the following beneficial effects:

[0017] 1. This negative pressure condensation purification method utilizes the characteristics of different water qualities under various operating conditions and combines them with the physical principle of heat exchange to achieve effective liquid separation and obtain pure liquid and its solidified products. Compared with existing purification technologies, it can handle liquids under various water quality conditions, making it widely applicable in different industrial and environmental protection scenarios. This method relies on the principle of heat exchange, which can utilize energy more efficiently, reduce energy consumption, and achieve electricity savings. It also reduces the required heating or cooling, thus achieving heat savings. Through negative pressure and condensation, impurities can be removed more effectively, resulting in a purer liquid. It also achieves cleaner separation of solids.
