Embodiment Construction

[0016] see figure 1 and 2 , the embodiment of the present invention is provided with a reaction chamber 1, an insulating cover 2, an electrode moving groove 3, an air outlet 4, a high-voltage external electrode 5-1, a grounding external electrode 5-2, a ventilating insulating sleeve 6-1, and a closed insulating sleeve Tube 6-2, high-voltage internal electrode 7-1, grounding internal electrode 7-2, stirrer 8, AC power supply 9, gas cylinder 10, and DC power supply 11; the specific implementation process is as follows: Prepare the solution, put it into the reaction chamber, open The gas cylinder and the stirrer apply voltage to the high-voltage internal electrode 7-1 through the AC power supply 9 . During the voltage rise process, the mixture produces thick smoke, which is discharged from the vent hole. After reacting for a period of time, turn off the AC power supply 9 . Turn on the DC voltage, pressurize the external electrode 5-1, and stop increasing the voltage after the ...

Abstract

The invention provides a plasma liquefaction device and relates to biomass liquefaction. The plasma liquefaction device comprises a reaction chamber body, an insulating cover, an electrode moving groove, a stirrer, outer electrodes, insulating bushes, inner electrodes, an AC (alternating current) power supply, a gas cylinder and a DC (direct current) power supply, wherein the reaction chamber body is arranged on the stirrer and covered with the insulating cover; the electrode moving groove is formed in the insulating cover and allows the electrodes to move left and right, different discharge areas can be formed through change of electrode distance, and the insulating bushes are arranged between the outer electrodes and the inner electrodes; the inner electrodes comprise a high-voltage inner electrode and a grounding inner electrode and are used for dielectric barrier discharge; the outer electrodes comprise a high-voltage outer electrode and a grounding outer electrode and are used for arc discharge; the insulating bushes are connected with the gas cylinder filled with inert gas which is used for generating plasma through dielectric barrier discharge of the inner electrodes; a gas outlet hole for gas exhausting is formed in the middle of the insulating cover; the high-voltage outer electrode is connected with a DC power supply high-voltage electrode, and the grounding outer electrode is connected with a DC power supply grounding electrode.

Description

technical field [0001] The invention relates to biomass liquefaction, in particular to a plasma liquefaction device. Background technique [0002] Biomass energy is renewable, can replace fossil energy, and can be converted into carbon resources of liquid and gaseous fuels and other chemical raw materials or products. Biomass liquefaction technology is one of the most potential biomass energy utilization technologies. At present, biomass direct liquefaction technologies include high-pressure liquefaction technology, rapid pyrolysis liquefaction technology, liquefaction agent liquefaction technology under normal pressure, etc., and liquefaction agent liquefaction mainly includes phenol liquefaction and polyol liquefaction. At the same time, critical technology and microwave technology have also been introduced into biomass liquefaction. However, as far as the current biomass liquefaction process is concerned, it mainly adopts the method of high temperature and high pressure...
