Carbon-containing waste gasification furnace and gasification method of carbon-containing waste

Abstract

The invention provides a carbon-containing waste gasification furnace and a gasification method of carbon-containing waste. According to the carbon-containing waste gasification furnace and the gasification method of the carbon-containing waste, the combustible waste gas and the combustible carbon-containing waste can be integrated in one gasification furnace by utilizing the gasification furnace, high energy can be conveniently provided by utilizing the combustible waste gas by utilizing the gasification furnace, and the gasification of the combustible carbon-containing waste is promoted to generate synthesis gas. The gasification furnace comprises a gasification chamber and a chilling chamber, a slag discharging opening is formed in the bottom of the gasification chamber, a descending pipe is arranged right below the slag discharging opening, and a burner is installed on the top of the gasification chamber. The burner comprises a center annular channel used for inputting combustible waste gas, a first annular channel used for inputting an oxidizing agent, a second annular channel used for inputting combustible carbon-containing waste and a third annular channel used for inputting the oxidizing agent, all of which are sequentially arranged in a sleeving mode from inside to outside. A combustion space for combustible waste gas and the oxidizing agent to react is reserved between an outlet in the bottom of the center annular channel and an outlet in the bottom of the first annular channel; and a purging device is arranged between the slag discharging opening and the descending pipe, and a purging opening is formed in the purging device.

Description

technical field [0001] The invention relates to the treatment and utilization technology of carbon-containing waste, in particular to a carbon-containing waste gasification furnace and a carbon-containing waste gasification method. Background technique [0002] Solid carbon-containing waste such as sludge, livestock and poultry waste and other biomass resources have large reserves, wide distribution, and are renewable. Their S, N, and ash contents are low, and the sulfur, nitrogen oxides, and dust emissions after combustion are relatively high. Fossil fuels are also much smaller and more environmentally friendly. However, due to the low quality and energy density of carbonaceous waste and high moisture content, it is not easy to store and transport. If it is directly used as fuel, the thermal efficiency of combustion is low and seriously pollutes the environment. At present, the use of pyrolysis or gasification processes has been proposed in the industry to convert carbon-...

AI Technical Summary

Problems solved by technology

The pretreatment process is complex and consumes more energy, resulting in unnecessary waste and high cost

[0003] Gas combustible waste, such as the excess coke oven gas and hydrogen produced by most chemical plants, will be burned directly through the waste gas torch if it cannot be further utilized, which is a serious waste of energy
