Whirlwind type separation juice extracting method and equipment

Abstract

The invention relates to an evaporation and sugar boiling method and equipment in a cane sugar factory, in particular to an entrainment separation juice extracting method and a device. The device consists of a plurality of whirlwind separators, wherein the whirlwind separators are uniformly distributed on the top of an evaporation tank, juice steam enters into air inlets of a whirlwind juice extracting device in the tangential line direction at high speed, under the effect of the centrifugal force, liquid drips in the juice steam are thrown to the device wall to be separated, and the liquid drips flow back into the tank through U-shaped pipes arranged at the bottom of the whirlwind separators, so the liquid drips are prevented for being converted into fog again because of the steam flow impact, clean juice steam is discharged to the top from center pipes of the whirlwind separators, and the goal of separation is reached. The sugar loss of the evaporation tank and a sugar boiling tank is avoided, and the invention has the juice extracting effects that the sugar content of dual effect condensing water is reduced from a range between 100 ppm and 150 ppm to a range between 25 ppm and 40 ppm, and the boiler soft water standard is reached.

Description

technical field [0001] The invention relates to a sugar making method and equipment, in particular to a method and equipment for separating the mist and foam of sugarcane evaporation and boiled sugar. Background technique [0002] In recent years, with the improvement of the evaporation capacity of the evaporation tank, the evaporation efficiency has been enhanced, and the phenomenon of sugar running has become more and more serious. There are two reasons and phenomena of sugar running: [0003] One is to spray running sugar. The sugar juice is vaporized in the heating tube to form a vapor-liquid mixture, which is sprayed out from the heating tube. Generally, it splashes down before reaching the top of the tank, but when the pressure, vacuum, and liquid level fluctuate greatly, it will spray to the top of the tank, causing Running sugar, this phenomenon rarely happens in normal operation. [0004] The other is mist entrainment. After the mixture of sugar liquid bubbles is...

Problems solved by technology

[0010] The juice catcher disclosed above still has shortcomings, some have complex structures, some have poor separation effect, and the droplets are easy to generate mist in the juice catcher, so there are not many popularization and application in production at present.
