Abstract

The invention discloses an anti-coking agent for a hazardous waste incineration line. The anti-coking agent comprises the following components in percentage by mass: 40-70% of sintered alumina; 10-25% of sintered calcium oxide; 10%-30% of sintered silicon oxide; 5-10% of clay; 0-5% of an auxiliary agent; wherein the sum of the mass percentages of the components is 100%. The anti-coking agent provided by the invention can increase the melting temperature of the hazardous waste material, reduce the coking risk and improve the operation state of a hazardous waste incineration line.

Description

technical field [0001] The invention specifically relates to an anti-coking agent used in a hazardous waste incineration line and a preparation method thereof. Background technique [0002] When the hazardous waste incineration line incinerates waste, due to the variety of waste materials and complex components, substances with low melting points generated during the treatment process adhere to the walls of the equipment and pipelines, resulting in a poor operating state of the incineration line. In order to improve this phenomenon, it is necessary to develop an anti-coking agent for hazardous waste incineration lines. Contents of the invention [0003] The purpose of the present invention is to provide an anti-coking agent for hazardous waste incineration line and its preparation method in order to solve the above problems, which can increase the melting temperature of waste materials and reduce the risk of coking. [0004] The purpose of the present invention is achieve...
