Furfural steam slag separation and recovery device and recovery method thereof

Abstract

The present invention provides a furfural steam slag separation and recovery device and a recovery method thereof. A furfural steam slag separation and recovery device includes: a gas slag separator, which has a feed port for accessing furfural steam slag, and centrifuged The first outlet of the exhaust gas and the second outlet of the waste residue; the first condenser, which has a first cold medium flow channel and a first heat medium flow channel, and the inlet of the first heat medium flow channel communicates with the first outlet; the liquid storage tank , which communicates with an outlet of the first heat medium flow channel, and is used to store the first condensate; a hydraulic ejector, which has a water inlet, an air inlet, and a water outlet, and the water inlet and the water outlet are connected to the liquid storage The slots communicate, and the air inlet communicates with the other outlet of the first heat medium flow channel. The device of the invention has simple structure and convenient operation, can separate and recycle furfural slag, protects the environment and turns waste into treasure.

Description

technical field [0001] The invention belongs to the technical field of furfural production, and in particular relates to a furfural slag separation and recovery device and a recovery method thereof. Background technique [0002] At present, in the furfural production process in my country, most enterprises discharge furfural slag and waste gas of furfural and acetic acid into the slag shed together, and the waste gas is discharged into the atmosphere through the skylight or the exhaust port. Although a small number of enterprises have adopted gas slag separation facilities or devices, they often discharge the separated waste gas to the air without recycling, causing serious pollution to the atmosphere. This is because: the waste gas contains some furfural and acetic acid, and the waste gas diffuses into the atmosphere In the middle, the smell is unpleasant, which causes serious pollution to the surrounding environment of the enterprise and has a great impact on the lives of ...

AI Technical Summary

Problems solved by technology

Although a small number of enterprises have adopted gas slag separation facilities or devices, they often discharge the separated waste gas to the air without recycling, causing serious pollution to the atmosphere. This is because: the waste gas contains some furfural and acetic acid, and the waste gas diffuses into the atmosphere In the middle, the smell is unpleasant, which causes serious pollution to the surrounding environment of the enterprise and has a great impact on the lives of residents; the direct discharge of waste gas results in poor production environment in the workshop, which will damage the health of employees and fail to meet the requirements of clean production; Furfural cannot be recycled, resulting in a waste of production resources and an increase in cost;

[0003] my country's furfural production accounts for about 70% of the world's production, but the furfural slag separation process is still at the level of the 1960s, and there is a big gap compared with developed countries
