preparation example Construction

[0019] The present invention provides the preparation method of the environment-friendly water treatment agent that the present invention provides for central air-conditioning chilled water treatment, comprises the following steps:

[0020] Step 1: 10 to 25 parts by weight of polyepoxysuccinic acid, 2 to 5 parts by weight of potassium chloride, 3 to 10 parts by weight of 2-phospho-1,2,4-butane tricarboxylate, 3 Add ~14 parts by weight of lignin into 3~10 parts by weight of deionized water, heat and stir at 40~50°C until completely dissolved, then add 2~8 parts by weight of hydrolyzed maleic anhydride, 1~3 parts by weight of Dimethylformamide, 4-8 parts by weight of dodecyl dimethyl benzyl ammonium chloride, then heat up to 70-80°C, add 4-5 parts by weight of polyacrylic acid salt, keep warm for 3-5 hours, and then Add 3 to 5 parts by weight of citric acid and 5 to 8 parts by weight of ethanol in sequence for mixing, cool to below 28°C, then add 10 to 12 parts by weight of phos...

Embodiment 1

[0042] The preparation method of the environment-friendly water treatment agent for central air-conditioning chilled water treatment comprises the following steps:

[0043] Preparation of Chinese herbal medicine water extract: mix and decoct equal masses of Artemisia argyi, Cnidium, Perrin, pomegranate peel and licorice, filter, and concentrate to a solution with a soluble solid content of 0.3g / mL;

[0044] Preparation of the water extract of soybeans: Wash the soybeans, add 3 times the weight of water at a temperature of 30°C (meaning that the weight of the water is 3 times the weight of the soaked soybeans), soak for 12 hours, break into a muddy state, and then Filter to obtain white emulsion with 80 order filter cloths; In gained white emulsion, add the pure water of 4 times of volume (referring to the volume of pure water is 4 times of white emulsion volume), then add 500mg / L chitosan and carry out flocculation, After filtering to remove slag, the water extract of soybean ...

Abstract

The invention provides an environment-friendly water treatment agent for central air-conditioning frozen water treatment and a preparation method thereof, comprising polyepoxysuccinic acid, potassium chloride, 2-phosphate-1,2,4-tricarboxylic butane, Add lignin to deionized water, heat and stir, then add hydrolyzed maleic anhydride, dimethylformamide, dodecyldimethylbenzyl ammonium chloride, heat up to 70-80°C, add polyacrylate, and then add Mix citric acid and ethanol, add phosphorus-free corrosion inhibitor, soybean water extract, ε-polylysine and Chinese herbal medicine water extract after cooling, mix and spray dry to obtain the first mixed powder; mix the first mixed powder and solid The acid agent is mixed to obtain the second mixed powder; the solid alkali agent and the filler are mixed to obtain the third mixed powder; the second mixed powder, the third mixed powder and the lubricant are mixed and then tabletted to obtain the target product. The water treatment agent prepared by the method of the invention is environmentally friendly, has good scale and corrosion inhibition effects, and is convenient for later use.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning water treatment, in particular to an environment-friendly water treatment agent for central air-conditioning chilled water treatment and a preparation method thereof. Background technique [0002] The central air-conditioning circulating water treatment is realized through the circulating water system of the central air-conditioning. The circulating water system of the central air conditioner mainly includes two parts: the chilled water system and the chilled water system. The chilled water system is an open circulation system, while the chilled water system is generally a closed circulation system. [0003] Circulating chilled water often uses soft water as circulating water. The water is not concentrated or evaporated. The system mainly produces metal corrosion. The corrosion products increase the thermal resistance of the heat transfer surface and the roughness of the metal sur...
