Plasma pyrolysis system

Abstract

A plasma pyrolysis system relates to a plasma device and comprises a triphase rectifier, a high frequency power source and a plasma device; a triphase alternating current circuit is connected to a triphase alternating current input interface of the triphase rectifier; a monophase alternating current circuit is connected to a working frequency input interface of a high frequency power source; an isolator is arranged in the system; a direct current output interface of the triphase rectifier is connected to a direct current input end of the isolator; the plasma device consists of a first discharging component and a second discharging component; a first electrode, a second electrode, a third electrode are arranged in the first discharging component; a fourth electrode is arranged in the second discharging component; a high frequency output interface of the high frequency power source is connected to the first electrode; the direct current output end of the isolator is connected to the second electrode; a direct current loop interface of the triphase rectifier is connected to the fourth electrode. A plasma gasifying manner is adopted to perform ionization activation and then perform pyrolysis treatment through a second-class hyperthermia plasma arc on water vapor to dissolve the water vapor into active substances of hydrogen and oxygen to be used as a gasifying agent.

Description

technical field [0001] The invention relates to electromechanical equipment, in particular to a power supply for plasma equipment. Background technique [0002] The gasification agent used in the conventional gasification device is water vapor + air or water vapor + oxygen. When the gasifier is working, the water vapor + air or water vapor + oxygen are directly sent into the gasifier to make the water vapor and Coal undergoes a gas-forming reaction to generate synthesis gas, which is an endothermic reaction that requires the oxidation reaction of air or oxygen and carbon to provide heat for it. The gasification rate of this gasification method is low, and at the same time, a large amount of Carbon dioxide waste gas not only affects the quality of synthesis gas, but also causes a large amount of greenhouse gas emissions in post-production.

[0002] The gasification agent used in the conventional gasification device is water vapor + air or water vapor + oxygen. When the gasifier is working, the water vapor + air or water vapor + oxygen are directly sent into the gasifier to make the water vapor and Coal undergoes a gas-forming reaction to generate synthesis gas, which is an endothermic reaction that requires the oxidation reaction of air or oxygen and carbon to provide heat for it. The gasification rate of this gasification method is low, and at the same time, a large amount of Carbon dioxide waste gas not only affects the quality of synthesis gas, but also causes a large amount of greenhouse gas emissions in post-production

Due to the low calorific value of domestic waste and the low content of fixed carbon in its chemical composition, if conventional gasification technology is used to gasify domestic waste, the endothermic reaction between water vapor and domestic waste will consume the energy of the gasifier. The gasification furnace needs to add coal fuel and input air or oxygen to support the combustion, so that the exhaust gas content in the synthesis gas is high, and the useful components in the obtained synthesis gas are quite low, almost exhaust gas, which cannot meet the application requirements of chemical raw materials
