Abstract

The invention discloses a salt inhibitor applied to a hazardous waste incineration environment. Ethylene diamine tetramethylene compounds and fatty alcohol polyoxyethylene alcohol ethers are used as main materials, organic phosphate, polymaleic acid (anhydride) (sodium / potassium), polyaspartic acid (sodium / potassium), polyepoxysuccinic acid (sodium / potassium), polyacrylic acid (sodium / potassium),oxide, chloride or carboxylic acid (or sulfonic acid) salt compounds are used as auxiliary materials, and through good chelation, low-limit inhibition and lattice distortion effects, and favorable dispersity of the polymer on the salt, lower salt deposition tendency of the salt, stable complex formation, dissolution reaction promotion and gradual dissolution of the original salt layer are realized, the functions of salt inhibition and salt removal are achieved, and the salt inhibitor is well applied to the field of hazardous waste incineration.

Description

technical field [0001] The invention relates to a water treatment agent used in a hazardous waste incineration project, in particular to a salt inhibitor used in a waste salt disposal system. Background technique [0002] Comprehensive hazardous waste disposal plants generally include disposal facilities such as hazardous waste incineration systems, physical and chemical disposal systems, landfill pretreatment systems, small sewage treatment stations, and bucket washing rooms, as well as living areas for employees. The wastewater discharged from these equipment and facilities is collected to the sewage treatment station in the factory area for disposal. After the wastewater is treated by air flotation redox acid-base neutralization, flocculation sedimentation, aeration and filtration treatment process, high-salt wastewater with high conductivity and wide pH value range can be obtained. . The function of the quenching tower of the hazardous waste incineration system is to co...
