Abstract

The invention discloses a liquid sulfur dioxide production device and method. The device comprises a sulfur melting tank, a sulfur burning spray gun, a sulfur combusting furnace, an air exchanger, a desulfurizing tower, a purifying device, a compressor, an oil filter and a SO2 condenser, an outlet of the sulfur melting tank is connected with a liquid sulfur inlet of the sulfur burning spray gun, anozzle of the sulfur burning spray gun is connected with the sulfur combusting furnace, a flue gas outlet of the sulfur combusting furnace is connected with the air exchanger which is connected witha flue gas inlet of the desulfurizing tower, a flue gas discharging port of the desulfurizing tower is connected with the purifying device which is connected with the compressor, and the compressor isconnected with the oil filter which is connected with the SO2 condenser. The device is high in product quality, sulfur dioxide (SO2), residue and moisture contained in liquid sulfur dioxide producedby the device are greater than or equal to 99.97%, less than or equal to 0.010% and less than or equal to 0.020% respectively, and indexes reach superior-product requirements in liquid sulfur dioxideproduct quality standards; three wastes are discharged in an up-to-standards manner, so that no damage is caused to environment, energy consumption is reduced, and cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of liquid sulfur dioxide production, and in particular relates to a liquid sulfur dioxide production device and a method thereof. Background technique [0002] Liquid sulfur dioxide is a colorless transparent liquid with a pungent odor. Relative density 1.43 (0 degrees), soluble in water, ethanol and ether. In the presence of a high-temperature catalyst, it can be reduced to hydrogen sulfide by hydrogen and sulfur by carbon monoxide. Liquid sulfur dioxide is also a good solvent for various compounds in industry. It can be used as reducing agent, refrigerant, preservative, bleaching agent and other raw materials for organic products. It is often used in non-ferrous smelting, pesticides, medicine, artificial Fiber and dye industries. [0003] In the production of liquid sulfur dioxide, pure sulfur dioxide gas is usually produced first, which is then liquefied by compression or freezing. The traditional pur...
