Disclosed is a multi-stage sedimentation rake-free thickening device. The device includes a central tank. A diversion sedimentation zone is arranged on the outside of the center tank. The diversion sedimentation zone includes an annular diversion sedimentation screen and a concentrated magnetic shower. The annular diversion sedimentation screen includes an annular groove spirally arranged around a central groove body. The annular groove is sequentially arranged with second spoiler baffles along the length direction. The lower bottom plate of the annular groove is also provided with second underflow discharge port. Multiple second inclined plate diversion discharge pipe is arranged under the corresponding second underflow discharge ports. The outlets of all the second inclined plate guide discharge pipes are collected to the second underflow discharge pipe, and the settled water is discharged from the second overflow discharge pipe arranged at the end of the annular groove.

A vapor recovery apparatus degasses oil and water produced by an oil well. The apparatus has a first vessel forming a column. Oil containing gas enters the bottom of the first vessel and flows up to a liquid outlet. Heat is applied to the rising oil, wherein the oil foams. Gas escapes into the upper end. The foam flows into a second column and along a roughened surface. The bubbles in the foam break apart, releasing the gas. The oil flows down the second column to an outlet. Water is introduced into a third vessel. The water releases gas therein, which gas mingles with the gas from the oil. The third vessel is located around the first and second vessels. A compressor may be used to withdraw the gas and provide hot compressed gas to heat the rising oil in the first column.

A plant for dealcoholising alcoholic beverages includes a rectification column having at least one inlet for the alcoholic beverage, a sump and a top. The rectification column is operable such that dealcoholised beverage can be removed from the sump and exhaust vapour can be removed from the top. At least one evaporator is configured to supply the rectification column with vapour. A condenser arrangement condenses the exhaust vapour removed from the top of the rectification column, at least in part. The plant further includes a heat pump which can operate the evaporator as well as the condenser arrangement. A method for dealcoholising alcoholic beverages in a rectification column is also disclosed.

Disclosed is a reverse flow multi-stage sedimentation rake-free thickening device relating to the field of slime water treatment. The device includes a feed assembly, a guide assembly, and a clean coal collection assembly. The guide assembly also includes a central tank body and coal slurry flows from the upper part of the central tank body to the inner side wall of the central tank body through the feed assembly and the medicament, and then flows to the middle of the central tank body through the guide assembly. After the reaction, the bubbles carry the fine coal slime and move up to the clean coal collection assembly. The clean coal collection assembly is located above the outlet of the guide assembly, and the clean coal collection assembly is sequentially provided with a central collection area, a defoaming area, and a diversion settlement area from the middle to the outside.
