Abstract

The invention aims to provide a chlorine fixing agent suitable for reducing chloride emission in combustion gas of tail gas waste derived fuel. The chlorine fixing agent comprises the following components of acetylene sludge, fly ash and exciting agent in percentage of (60-80): (15-30): (3-10) by weight. With the adoption of the chlorine fixing agent, the purpose of treatment of wastes with processes of wastes against one another is realized; the waste is extruded into waste gas waste derived fuel at normal temperature under normal pressure, and the energy consumption is low; the volatilization rate of S-element and Cl-element are reduced greatly, so the chlorine fixing agent is beneficial for the waste combustion treatment; and the inflaming property of the waste is reduced. The waste derived fuel prepared by the preparation method has high compressive strength, and is suitable for the subsequent use of the waste derived fuel in combustion furnace and gasification furnace.

Description

technical field [0001] The invention belongs to the field of treating solid fuels for improving combustion, and particularly relates to a chlorine fixation agent suitable for garbage-derived fuels and its preparation method and application. The raw materials of the chlorine fixation agent include calcium carbide slag, fly ash, excitation agent; the chlorine-fixing agent can increase the molding rate and compressive strength of the garbage-derived fuel on the garbage sieve. Background technique [0002] With the continuous expansion of city scale, the increasing urban population and the continuous improvement of people's living standards, the generation of urban domestic waste is gradually increasing. As early as 1996, the volume of urban waste removal in China had reached 100 million tons, and it was growing at a rate of 8% to 10% every year. The annual accumulation of garbage has reached more than 6 billion tons, and more than 200 cities across the country have been surrou...
