Abstract

The invention provides a cleaning agent for cleaning calcium sulfate scale. The cleaning agent comprises the following components in percentage by weight: 10 to 30 percent of sodium citrate, 0.5 to 5 percent of dodecyl dimethyl benzyl ammonium chloride, 0.5 to 5 percent of sodium di-iso-octyl maleate sulfonate, 5 to 15 percent of absolute ethanol and 45 to 85 percent of reverse osmosis water. The cleaning agent for the calcium sulfate scale is particularly used for removing insoluble calcium sulfate scale, can completely remove the scale, does not corrode metals, is nontoxic to human bodies and is efficient and safe, a medicament is a neutral solution, waste liquid can be safely discharged, and a phenomenon of hydrogen embrittlement can be avoided.

Description

technical field [0001] The invention belongs to the technical field of industrial circulating cooling water treatment, and in particular relates to a calcium sulfate scale cleaning agent. Background technique [0002] Scaling problems are often encountered in industrial production such as mine salt mining and transportation, seawater desalination, oil and gas field development, and boilers. The accumulation of scale layers not only affects heat transfer efficiency, causes heat energy loss, and reduces output, but also increases production costs. The production cycle is prolonged, the equipment is corroded, the service life of the equipment is shortened, and the safe production is endangered. Therefore, scaling must be dealt with regularly. The common types of scale are carbonate scale, sulfate scale, silicate scale, mixed scale, iron oxide scale, oil scale and so on. At present, there is no way to thoroughly clean calcium sulfate scale. The removal of calcium sulfate scale...
