Device for desulfurizing electrolyzed water coal slurry to produce hydrogen

Abstract

The invention provides a device for desulfurizing electrolyzed water coal slurry to produce hydrogen, which has the advantages that the hydrogen is produced in a process of desulfurizing coal and the desulfurizing speed is high. The device comprises a material distribution system, an electrolysis system, a gas recycling system and a coal recycling system, wherein the material distribution system comprises a funnel feeding machine, a microwave drying machine, a belt conveyor, a powder mill, a material distribution funnel, a dry powder agitator and a slurry agitator; the electrolysis system comprises agitation tanks, an electrolysis tank, a direct-current pulse power supply cabinet, a microwave irradiation device, ultrasonic vibration rods, an electrode and a pipe net; a submerged pump is arranged in a separation plate between the two agitation tanks; the outlet of the pump is communicated with the pipe net at the bottom of the electrolysis tank by an electrolyte pipe; the electrode is vertically arranged at the center of the electrolysis tank and is of a closed square shape surrounded by four sets of electrode plates; the ultrasonic vibration rods are arranged on the two sides of the electrode in the electrolysis tank; and the gas recycling system comprises a carbon dioxide storage tank, a hydrogen storage tank, a pressure gauge, a flow meter, a check valve, a stop valve, a gate, a hydrogen analyzer, an emptying valve, a buffering tank and a boosting pump.

Description

technical field [0001] The invention relates to a device for producing hydrogen by electrolytic desulfurization of coal-water slurry. Background technique [0002] Coal-water slurry electrolytic desulfurization hydrogen production is to conduct DC pulse current electrolysis in the electrolytic cell through the coal-water slurry electrolyte, and generate hydrogen and carbon dioxide gas at the cathode and anode respectively; simultaneously remove the inorganic sulfur and organic sulfur in the coal, and produce low-sulfur refined coal or coal water slurry. Under the dual pressure of energy shortage and environmental pollution, hydrogen energy has long been included in the key breakthrough fields of scientific circles in various countries. According to reports at home and abroad, most of the research on this technology is still in the laboratory, and there is still a lack of efficient special equipment for hydrogen production by electrolytic desulfurization of coal-water slurry...
