Electric generator hydrogen cooler chemical cleaning agent and application

Abstract

The invention discloses an electric generator hydrogen cooler chemical cleaning agent and application. The cleaning agent comprises a cleaning agent A and a cleaning agent B, wherein the cleaning agent A mainly comprises the following components: a non-oxidizing sterilizing agent, a surfactant, a dispersing agent and a deionized water solvent; the cleaning agent B mainly comprises the following components: polyepoxysuccinic acid, sulfamic acid, hydrochloric acid, a nonionic surfactant polyoxyethylene ether, urotropin, an imidazoline type corrosion inhibitor and a deionized water solvent; and the application method comprises the steps of mounting a cleaning system, preparing the cleaning agent A, circularly cleaning the cleaning agent A, replacing waste liquid, preparing the cleaning agentB, circularly cleaning the cleaning agent B as well as treating and replacing the waste liquid. The chemical cleaning agent provided by the invention has excellent cleaning effect, is simple and convenient in application process, has high operability, can realize complete dissolution of hydrogen cooler scale and corrosion products, can guarantee that the unit can eliminate the defect and remove scales, can recover the heat exchange efficiency of the hydrogen cooler and can guarantee safe and stable operation of the electric generator.

Description

technical field [0001] The invention relates to the technical field of chemical products, in particular to a cleaning agent for a hydrogen cooler of a generator and its application. Background technique [0002] The hydrogen cooler is a device for heat exchange between hydrogen and cooling water, and is an important part of the generating set of a thermal power plant. In order to ensure the safe and stable operation of the generator set, the cold hydrogen temperature of the generator must be controlled within the specified range. Once the cold hydrogen temperature is too high, the heat of the stator and rotor coils of the generator cannot be taken away smoothly, and the generator set will face shutdown. Serious consequences. Especially in summer, the temperature is high. When the temperature is above 38°C, the hydrogen temperature at the outlet of the hydrogen cooler will increase accordingly, and may reach the alarm value of 46°C or even exceed this value, which will serio...
