Plasma fluid bed gasifying device

Abstract

The invention relates to a plasma fluid bed gasifying device, relating to plasma gasification furnace equipment. The plasma fluid bed gasifying device mainly comprises a top cover, an upper furnace body, an insulated connecting piece, a lower furnace body, an anode, a cathode and a base, wherein the cathode is arranged in an inner space at the upper part of the lower furnace body; the upper cylindrical end of the cathode is in a horn mouth shape; the outer edge of the horn mouth is provided with a spiral groove; the insulated connecting piece is arranged between the anode and the lower furnace body; through holes in the axle center of the anode form a compressed hole channel; a horn mouth at the outlet of the compressed hole channel forms an anode arc root zone; the anode is internally provided with a cooling water sleeve; the upper furnace body is arranged on the anode; the inner space of the upper furnace body forms a gasification zone; and the top cover is provided with a synthesis gas output port for outputting synthesis gas. The plasma fluid bed gasifying device utilizes the characteristics that gasification raw materials of a fluid bed are wide in adaptability and high-temperature particles move seriously inside the gasification zone so as to strengthen heat transfer, and meanwhile, high-temperature working air at more than 4000 DEG C is taken as fluidized wind, so that coal or garbage biomass is quicker in gasification, higher in gasification efficiency and lower in energy consumption, and hydrogen-enriched synthesis gas with higher quality can be obtained.

Description

technical field [0001] The invention relates to gasification equipment, in particular to a plasma gasification furnace equipment. Background technique [0002] At present, in conventional coal gasification devices, water vapor + air or water vapor + oxygen are sent into the gasification furnace as a gasification agent, so that water vapor and coal undergo a gas-forming reaction to generate synthesis gas. The reaction is an endothermic reaction, which requires air Or the oxidation reaction between oxygen and carbon will provide heat for it. This gasification method will increase the consumption of coal resources. At the same time, a large amount of carbon dioxide waste gas will be generated in the synthesis gas, which will not only affect the quality of the synthesis gas, but also cause a large amount of emissions in the subsequent production. of greenhouse gases. [0003] With the improvement of people's living standards and the development of cities, the amount of domestic...
