Plasma combustion-supporting Swiss roll combustor

Abstract

The invention provides a plasma combustion-supporting Swiss roll combustor and belongs to the technical field of low-heating-value gas utilization. The combustor comprises a combustion chamber and a spiral plate type channel. The combustor specifically comprises a combustor shell, a flow guide plate, a porous medium, a gas inflow channel, a gas outflow channel, a discharge device, an ozone addition opening, a thermometer hole, an ignition hole, an observation hole, a metal high-voltage electrode plate, an electrode leading-out wire and an exhaust chimney. The combustor is round or square. The upper end and the lower end of the combustor are sealed through sealing plates. The gas inflow channel and the gas outflow channel are formed in the two ends of the spiral plate type channel. The porous medium is located in the center of the combustion chamber. The inner wall of the combustion chamber is coated with a heat-resisting material. The combustion chamber is wrapped by a heat insulating material. The discharge device and the flow guide plate are located in an inlet of the combustion chamber. The ozone addition opening is formed in the outermost ring of the spiral plate type channel. According to the combustor, the plasma discharge device or an ozone generator and the porous medium material are combined, and the purposes of reducing energy consumption, eliminating poison and the like can be achieved.

Description

technical field [0001] The invention relates to the technical field of low calorific value gas (exhaust gas) utilization, in particular to a plasma combustion-supporting swiss roll burner. Background technique [0002] my country is a country with a large energy demand, but the efficiency of energy utilization cannot reach a high level due to the defects of technical means. When people exploit and use various energy resources, some "waste gas" containing a small amount of combustible components and low calorific value is directly discharged into the atmosphere without being utilized, such as gas emitted during coal mining and torches in petrochemical industries. Evacuated hydrocarbon waste gas, associated natural gas discharged from oil and gas field exploitation, landfill gas generated from landfill, flammable and toxic waste gas generated during chemical industry production, etc. The direct discharge of these "exhaust gases" containing combustible components or toxic gase...
