Supramolecular care agent, heating circulating water zero discharge system and application method

Abstract

The invention discloses a super-molecular care agent, a heating circulating water zero discharge system and a use method. The super-molecular care agent comprises the components, by weight, of 7%-10% of sodium alkyl benzene sulfonate, 10%-12% of sodium polyacrylate, 5%-6% of dodecyl dimethyl benzyl ammonium chloride, 2%-2.5% of alkanolamide, 4.5%-6% of fatty alcohol-polyoxyethylene ether, 4%-5% of cyanoacetic acid, 1%-1.5% of benzotriazole, 2%-3% of sodium tripolyphosphate, 2%-2.5% of sodium silicate, 1%-1.5% of trisodium phosphate, 2%-3% of ethylene glycol, 1%-1.5% of pyridoxine hydrochloride, 2%-2.5% of disodium hydrogen phosphate and the balance of water. The super-molecular care agent is added to heating circulating water, scaling produced by the circulating water and the system corrosion degree are reduced, and the effect of reducing sewage discharge is realized.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a supramolecular care agent, a heating circulating water zero discharge system and a use method. Background technique [0002] At present, urban central heating is widely implemented, and the hot water generated by thermal power plants is transported to each household through the heating pipe network. However, the circulating water used in urban heating systems is easy to corrode and scale. The dirt on the heating pipe network is mainly rust, scale, etc., which adhere to the metal surface, because its thermal resistance is dozens of times that of metal. Even hundreds of times, it will seriously affect the heat exchange. In the prior art, in order to prevent scaling and corrosion of the boiler heating pipe network, phosphate is usually added to the heating system. The main function of phosphate is to prevent scaling of hot water. After entering the hot water system, th...

Problems solved by technology

However, in the actual use process, due to the use of high-fine graphite powder cannot be dissolved in water, high-fine graphite powder is easy to cover the metal surface of the refrigerant water system with scaling, and the scaling is covered by high-fine graphite powder, resulting in a care agent The scale cannot be cleaned quickly and effectively, so that a complete supramolecular protective film cannot be formed on the metal surface of the refrigerant water system, resulting in poor cleaning efficiency and effect of the central air-conditioning refrigerant water system
