Abstract

The invention discloses a method for preparing a water body greasy-dirt removing agent from calcium carbide furnace gas dust, and belongs to the field of comprehensive utilization of the calcium carbide furnace gas dust. The method for preparing the water body greasy-dirt removing agent from the calcium carbide furnace gas dust includes the following steps: mixing the calcium carbide furnace gas dust with iron pyrite, sodium chloride, sodium dodecyl benzene sulfonate and acid liquor, and stirring and drying the mixture to obtain the water body greasy-dirt removing agent. The invention further discloses the water body greasy-dirt removing agent prepared according to the method. The water body greasy-dirt removing agent can be used for removing greasy dirt in water bodies, and removal rate of the greasy dirt of the water bodies is high. The method has the advantages that the calcium carbide furnace gas dust is used for preparing the water body greasy-dirt removing agent, the method is simple to operate, raw materials have extensive sources, preparation cost is low, and reasonable utilization of the calcium carbide furnace gas dust is realized.

Description

technical field [0001] The invention relates to a method for preparing a water body oil stain remover by utilizing calcium carbide furnace gas dust, and also relates to the water body oil stain remover prepared by the method, which belongs to the field of comprehensive utilization of calcium carbide furnace gas dust. Background technique [0002] During the "Twelfth Five-Year Plan" period, driven by the rapid development of downstream industries such as polyvinyl chloride and 1,4-butanediol in China's calcium carbide industry, the production capacity of calcium carbide entered a period of rapid growth again. As of the end of 2015, there were more than 255 domestic calcium carbide enterprises in China, with a production capacity of 45 million t / year. Among them, the production capacity of the closed calcium carbide furnace with high level of technical equipment and remarkable energy saving and environmental protection effect reached 35.52 million t / year. Using a closed calci...
