Material conveying device and method for solid waste coupling combustion

Abstract

The invention discloses a material conveying device for solid waste coupling combustion, which comprises a high-pressure air inlet pipeline, a high-pressure air nozzle and a material receiving device,a material leading-in device is arranged on the material receiving device, the high-pressure air inlet pipeline is arranged on the material receiving device and is positioned on one side of the material leading-in device. The high-pressure air nozzle is connected with the high-pressure air inlet pipeline and arranged in the material receiving device. The material receiving device comprises a material inlet, the high-pressure air nozzle is located on one side of the material inlet and located below the material inlet, the material receiving device is connected with a mixing pipe, and the mixing pipe is connected with a diffuser pipe. The invention further discloses a material conveying method. According to the material conveying device and method for solid waste coupling combustion, the mixing distance between solid waste materials and high-pressure air or hot air can be effectively shortened, the operation precision of the material conveying device is improved, the flow adjusting range of the material conveying device is widened, and the blockage problem of the material conveying device is effectively solved.

Description

technical field [0001] The invention relates to a material conveying device and a conveying method for coupled combustion of solid waste, and belongs to the technical fields of solid waste treatment, garbage incineration, coupled combustion of coal-fired power plants, and the like. Background technique [0002] With the rapid development of my country's economy, the output of urban domestic waste and rural domestic waste is increasing year by year. According to statistics, since 2010, the volume of domestic waste removal and transportation in the country has shown an overall trend of increasing year by year. From 2010 to 2019, the compound annual growth rate of the national household waste removal volume reached 4.69%. As of 2019, the national household waste removal volume reached 2.28 billion tons. In 2020, the garbage removal volume will continue to maintain a relatively high growth rate. The national waste removal volume will reach 2.527 billion tons. At the same time,...
