Technology for manufacturing grinding aid through sodium hydrosulfite residue

Abstract

The invention discloses a technology for manufacturing a grinding aid through sodium hydrosulfite residue. The technology comprises the following steps of: preparing mother liquor through sodium hydrosulfite residue; and adding triethanolamine, glycerin, diethylene glycol, ethylene glycol and urea to the mother liquor according to the following certain mass ratio of 70 to 83% of mother liquor, 3 to 16% of triethanolamine, 3 to 10% of urea, 6 to 19% of glycerin and 5 to 18% of water. By adopting the technology for manufacturing the grinding aid through the sodium hydrosulfite residue, the problem of a production enterprise that the sodium hydrosulfite residue brings environmental pollution can be solved; moreover, the utilization rate of the residue is greatly increased; the residue can be applied to the cement industry as an economic grinding aid to realize the effects of energy conservation and consumption reduction.

Description

technical field [0001] The invention relates to the technical field of chemical waste residue treatment, in particular to a technology for manufacturing grinding aids from sodium dithionite residue. Background technique [0002] There are many sodium dithionite production enterprises that have a large amount of rectification tailings every day and cannot find the most reasonable and effective recycling method. Because of the environmental protection discharge of waste residue, the economic development of sodium dithionite enterprises has been troubled for a long time, and some sodium dithionite production enterprises have even been forced to close down. Another industry that supports the development of urban and rural construction in the country is the cement industry. The cement industry is a high-energy-consuming and high-emission industry. Although cement companies have adopted some energy-saving and consumption-reducing measures in recent years, there is still a lot of ...
