Description

The subject of the invention is the use of vacuum apparatus with a suspension chamber, chambers of steam pipelines with steam breakers at the lower end of the plant for cooking of sugar refineries operating on the basis of production of molten refined sugar.

The vacuum apparatus consists of a cylindrical detachable housing with conical niches and upper bottoms.

The bottom is equipped with a steam jacket, which serves for boiling so that it starts at the lowest part of the apparatus, preventing the masts of the mash and the usual release of flour crystal in this zone. When cooking refinery stuffed, this shirt will also melt to warm up the massecuite without vacuum, when it is lowered into a flat, or shape, with a closed pair on the hanging chamber. In addition, the steam jacket on the top of the apparatus is an additional working surface to the internal heating surface, which increases the intensity of the apparatus.

In the lower part of the apparatus, a single-drum steam chamber with a protrusion into a cone is suspended on three legs. A conventional circulation pipe is installed in the center of the chamber, inside which the circulation pipe passes downward of the apparatus for feeding syrup and passing the bubbling steam, ending with

distribution umbrella, which {1 guides the syrup under the pipe rack grates.

The lower end of the circulation pipe is released under the tube sheet, forming a hydraulic valve preventing the syrup from getting into this pipe, which is lighter and lighter than the massecuite, and such vapor evaporates, which can cause proper circulation to disappear.

The distribution zone is reinforced by a lap to the protruding end of the circulation pipe.

ITt of steel tubes is rolled into the first chamber.

The steam chamber has only one steam inlet fitting, one tube welded to it for draining condensate and one fitting for gas draining.

A dry steam tank with an internal special separator is installed in the upper part of the apparatus. The separator consists of three concentric cylinders, each of which has a vertical slit. The cross section of the latter is equal to the cross section of the air tube. The slots of the individual cylinders of the separator are offset by 180 ° relative to each other.

The separator operates according to a combination of the principle: the impact of oncoming steam jets, the assimilation of hollow liquid droplets suspended in a pair and the subsequent centrifugal release of liquid and the ambient flow of the ambassador to each target.

This principle of operation of the separator makes it possible to isolate the smallest hollow droplets that are contained in the vapors of solutions, are easier than the surrounding vapors and, with ordinary traps, make up the inevitable loss of the evaporated liquid.

. The liquid separated in the separator is automatically and continuously discharged from it through the pipe to the level of the boiling mass in the apparatus.

When the machine is lowered and steamed, its separator is rinsed on demand.

The device is equipped with inspection windows, a window for illuminating its internal subnet, an air inlet valve, a test valve, a massecuite release valve and all necessary fittings and instruments for controlling its operation.
