Problems solved by technology

Resin manufacturers recommend not to use ionic surfactants for cleaning ion exchange resins contaminated by oil. In the prior art, sodium hydroxide solution is generally used for alkaline cleaning or a compound solution of sodium hydroxide and non-ionic surfactants. Cleaning, this cleaning technology has a certain cleaning ability for ion exchange resins with slight oil pollution, but for ion exchange resins with severe oil pollution, the oil stains can not be cleaned, and the ion exchange resins cannot be cleaned. Function of regeneration and ion exchange
When using cationic surfactants and anionic surfactants for cleaning, the ionic surfactants are usually adsorbed by the resin and are not easily regenerated, resulting in new pollution, and the ion exchange resin loses its ion exchange function.

Abstract

The invention provides a washing agent for cleaning up machine oil pollution of an ion exchange resin. The washing agent comprises: by weight, 3 to 8% of sodium dodecyl benzene sulfonate, 1 to 4% of polyoxyethylene octylphenol ether, 0 to 2% of cocoanut fatty acid diethanolamide, 0.75 to 3% of fatty alcohol polyoxyethylene ether, 0.005 to 0.015% of an organosilicon antifoaming agent, 0.5 to 2% ofsodium chloride, 0.5 to 2% of an auxiliary agent A, 0.5 to 2% of an auxiliary agent B and the balance water. The washing agent contains an anionic surfactant and nonionic surfactants and is compounded with various auxiliary agents, and thus through the washing agent, machine oil pollution on the surface of an ion exchange resin can be cleaned up thoroughly; machine oil adsorbed in apertures of the ion exchange resin can be washed out; an exchange function of the ion exchange resin is recovered; and because of the adopted anionic surfactant, the ion exchange resin cannot be polluted again.

Description

technical field [0001] The invention is mainly used as a cleaning agent for cleaning ion exchange resin polluted by oil, especially a cleaning agent for cleaning ion exchange resin heavily polluted by steam turbine oil and sealing oil and used for condensate polishing treatment in power plants. Background technique [0002] Generating units, especially supercritical or ultra-supercritical thermal power generating units and nuclear power generating units, in order to prevent corrosion and scaling of the thermal system of the unit, the condensate must be 100% treated, and the condensate treatment method is ion exchange desalination. During the operation of the generator set, it is inevitable that the steam turbine oil and mechanical seal oil will leak into the thermal system. The leaked oil will pollute the ion exchange resin treated with condensate polishing, and the ion exchange resin will be lost after being polluted by oil. The ability of ion exchange, so that the corrosiv...
