Abstract

The invention provides a distillation system for preparing furfural, which comprises a distillation tower, a bottom fixing frame, a leading-in pipe, a leading-in valve, a stock solution box, a leading-in condensation frame structure, a gas outlet pipe, a circulating condensation frame structure, a leading-out pipe, a leading-out valve, a furfural metering tank, a discharge pipe, a discharge valve, a material receiving frame structure convenient to disassemble and a buffer support frame structure, the bottom fixing frame is mounted at the lower part of the distillation tower through bolts; the leading-in pipe is inserted into the lower part of the left side of the distillation tower; the leading-in valve is in threaded connection with the left side of the leading-in pipe; and the stock solution box is welded on the left side of the leading-in pipe. First semiconductor chilling plates are arranged in a staggered mode, the cooling speed of gas passing through the cooling pipe can be increased in the using process, and therefore the cooling speed of the gas can be increased; a jacking spring is arranged on the upper portion of the inner side of the supporting pipe, the buffering function can be achieved when the connecting cover is supported, and then the fixing disc and the bottom flange can be tightly attached.

Description

technical field [0001] The invention belongs to the technical field of furfural preparation, in particular to a distillation system for preparing furfural. Background technique [0002] Furfural, also known as furan formaldehyde, belongs to the heterocyclic furan aldehydes. It is a colorless and transparent liquid at room temperature and has a bitter almond smell. The industrial product is slightly yellowish. Melting point -38.7°C, boiling point 161.7°C, relative density 1.1594 (20 / 4°C). It can form 8.3% aqueous solution at 20°C, soluble in organic solvents such as ethanol and ether. Furfural is an industrial chemical product, which can be used as a raw material for organic synthesis, and is also used for synthetic resins, varnishes, pesticides, medicines, rubber, and paints. It is currently the only industrial production of furfural using plants as raw materials and acidic hydrolysis. method. The main raw materials of furfural are corncobs and cottonseed hulls. Hemicell...
