Stokehole fine feeding control method for melting device

Abstract

The invention discloses a stokehole fine feeding control method for a melting device. The method comprises the following steps of: firstly, carrying out equipment work at the early stage of feeding toensure that each running part can normally work, and then completely opening a gate valve at the bottom of a stock bin; turning on a rotation-resisting low-material-level switch on the stock bin, feeding materials into the stock bin, simultaneously starting a rotary valve feeder and a stirring device on a melting furnace, and feeding the materials into the melting furnace according to a set value; using a feeding induction device to detect the materials passing through a feeding port in real time; and judging the feeding state according to the real-time detection result of the feeding induction device, controlling all the running pars according to the judgment result of the feeding state, and achieving fine feeding in the melting furnace. According to the stokehole fine feeding control method for the melting device, fine feeding can be conducted on the melting furnace, the phenomenon of material accumulation or empty burning in the melting furnace is avoided, and it is guaranteed thatthe good waste heat treatment effect is achieved.

Description

Technical field[0001]The invention relates to the technical field of the stabilization and harmless treatment of solid waste incineration residues, and in particular to a furnace front fine feeding control method for a melting device.Background technique[0002]With the rapid development of the modernization process and the improvement of living standards, the output of municipal solid waste has also increased rapidly. The main methods of domestic waste treatment include landfill, incineration, and composting. Among them, waste incineration can achieve waste reduction, and the volume reduction after waste incineration can be as high as about 90%. In the incineration process, due to the high temperature, various pathogens in the waste can be eliminated to achieve the purpose of high temperature sterilization. Realize harmlessness. The waste heat from incineration can also be used for heating and power generation to realize resource reuse. However, a large amount of fly ash will be prod...

AI Technical Summary

Problems solved by technology

However, each subsystem in the existing plasma melting furnace is independent of each other, resulting in poor overall logical connection, making it difficult for the ion melting furnace to control the waste melting process, resulting in poor safety and poor stability, which greatly reduces the melting of waste. poor effect

However, the existing plasma melting furnace cannot carry out fine feeding, which makes the accumulation of materials in the plasma melting furnace easy to cause insufficient melting, reduces the heat treatment effect of waste, and easily causes empty burning in the plasma melting furnace Phenomenon, easy to damage the furnace body
