Embodiment Construction

[0009] In the figure, 1. Breathing interface, 2. Inhalation valve, 3. Exhalation valve, 4. Air outlet, 5. Purified gas buffer chamber, 6. Microporous filter membrane, 7. Antifouling agent layer, 8. Observation Hole, 9, air inlet, 10, air filter screen, 11, air chamber.

[0010] An embodiment of a high-purity water anti-fouling device suitable for adorning high-purity water anti-fouling agent of the present invention: it is to set two single-pass automatic opening and closing breathing valves 3 and suction valves 2 inside the high-purity water anti-fouling device. The valve 3 is used for directly exhaling air from the high-purity water container, and the suction valve 2 is used for inhaling air from the high-purity water container. It communicates with the purified gas buffer chamber 5 and the antifouling agent layer 7. Middle O 2 , CO 2 and organic and inorganic or microbial particles are removed; there is also an air chamber 11, which communicates with the antifouling agent...

Abstract

The present invention is a high-purity water antifoulant and its special-purpose container. The antifoulant consists of deoxidant less than 80 wt%, CO2 absorbent less than 60 wt%, biocide less than 40 wt% and malfunction indicator less than 1 wt%. The micro porous filter-purpose membrane has pore diameter smaller than 0.25 mm. The side special-purpose container is one with two one-way valve structures capable of being opened and closed automatically. When the antifoulant container is used, it is connected to the air breathing port of high-purity water container so as to eliminate O2, CO2, microbes and other particles. The present invention may be used widely in various industry and scientific research to prevent water quality from degradation.

Description

Technical field: [0001] The invention relates to a high-purity water antifouling agent and a high-purity water antifouling device, belonging to the technical field of water treatment. Background technique: [0002] In industries such as electric power, electronics, chemical industry, medicine and chemical laboratories, the method of preventing air pollution of high-purity water is generally to adopt the sealing method. The high-purity water in an independent container will naturally enter the air when it is taken; the high-purity water storage container in the industrial production process usually has a breathing port that communicates with the atmosphere, and the air can enter and exit freely. Due to its contact with air, high-purity water will increase dissolved oxygen, decrease pH, increase conductivity, particle pollution and microbial pollution, and the water quality will deteriorate. High dissolved oxygen and low pH in water are the main reasons for the corrosion of m...
