Description

The invention relates to the distillery industry, and in particular, to installations for purifying a water-alcohol mixture with activated carbon.

A known installation for cleaning a water-alcohol mixture with activated carbon, comprising a system of adsorbing columns connected in series with separators, with inlet and outlet pipes, a condenser-cooler, filters and a finished product collector.

Closest to what is proposed by its technical nature, is an installation comprising collectors of coal, water, recoverable defect, adsorber and filters.

The disadvantage of this installation is the loss of alcohol with exhaust air at

filling containers with water-alcohol mixture and coal in the process of its preparation for work. Due to the absence of the use of the coal dust fraction, the specific productivity decreases, while the installation does not have a mechanism for the selection of the coal dust fraction.

The aim of the invention is to increase productivity, reduce losses of alcohol and coal, and reduce labor costs.

To achieve this goal, a plant including charcoal, water, recoverable waste collectors, an adsorber and filters is additionally equipped with a vacuum system for loading activated carbon into the adsorber and separating the dust fraction, including a collection trap for mixing

dust fraction and alcohol vapor, a vacuum pump and a vacuum chamber mounted in the upper part of the adsorber coaxially with it.

In this case, the coal collector is communicated by a piping system with a vacuum chamber and the bottom of the adsorber with the formation of a circulation circuit of the wash water, and the collector-mixer is connected to the filters and the vacuum chamber.

It is advisable to install the vacuum pump in the lower part of the collector-mixer or outside it and communicate with the pipe with the collector angle dp return dust fraction.

For the first time in the proposed installation, due to the presence of a vacuum system, the process of lowering the adsorbent loading process into the adsorber is carried out with the separation, removal and collection of the dust fraction using a coal collector designed to separate the coal dust fraction and obtain a granular coal slurry; a vacuum chamber that separates and discharges air and a dusty fraction of coal and loads coal into an adsorber and a mixer-collector with a vacuum pump that perform the functions of creating a vacuum, trapping the dusty fraction of coal and mixing it with a liquid to form a suspension for further its use in the process.

In this installation, the collector-mixer with a vacuum pump serves not only to create a vacuum, to trap and mix the pulverized coal fraction with the liquid, but also to disperse air in the liquid. That is, due to the presence of a turbine, a new function is carried out - the absorption of alcohol impurities from the exhaust air when the adsorber and filters are filled with a water-alcohol mixture. Connecting the collector-mixer using the piping system to the filters, the vacuum chamber and the collector of correctable marriage allows you to capture the exhaust air saturated with alcohol vapors when filling the adsorber and filters with a water-alcohol mixture and carried out the process of absorption of alcohol vapor from a finely dispersed gas-liquid mixtures, dispose of alcohol, forming a water-alcohol solution in the mixer-mixer, return it to the process, send it to the collection of recoverable defects.

The drawing schematically shows the proposed installation,

The installation includes a collection tank of softened water 1, an adsorber 2, a collector with cartridges 3, a device for hydraulic discharge of coal 4, a pre-filter for water-alcohol mixture 5, a fine filter 6 and a collection of recoverable

reject 7, as well as a vacuum system consisting of a collector of coal 8, a vacuum chamber 9. of a collector-mixer 10 and a vacuum pump 11. In addition, the installation includes pipelines: water 12, suspension of coal 13, water-alcohol mixture 14, coal dust aerosol 15, alcohol vapor aerosols 16, vodka 17 and air 18.

Installation works as follows.

The adsorber 2 and the collection tank 10 are pre-filled with water. The vacuum pump 11 is turned on, checking the system. Coal is loaded into coal collector 8,

5, the dust fraction is separated. from the granular fraction and with a stream of air is directed to a vacuum chamber 9, from which it is discharged to a mixer-collector 10, where it is mixed with water and the purified air is discharged into the atmosphere. The grains of coal captured in this way, due to a sharp drop in speed during the tangential introduction of the flow, are lowered into the adsorber. Water from the water collector 1 is tangentially supplied to the coal collector 8 to form a suspension of coal, which is sent through the vacuum chamber 9 to the adsorber 2, subsequently supplying circulating water from the adsorber to the coal collector 8. In this case, a constant water level is maintained in the adsorber and collector 8. Then water is supplied to the collector with cartridges 3 located at the bottom of the adsorber and along a circuit including collector 3, adsorber 2, vacuum chamber 9, and

5 coal collector 8, washing the coal with water. After draining the water from the adsorber 2 and the charcoal collector 8, the pulverized coal slurry from the mixer-collector 10 is sent to the charcoal collector 8 for use as 0. In order to additionally process the water-alcohol mixture, if it is necessary to increase the productivity, the collector-mixer 10 is filled with water and the alcohol recycling circuit is included in the operation. WITH

5 for this purpose include a vacuum pump 11 when filling the pre-filter 5, adsorber 2 and the fine filter with a water-alcohol mixture in the process of bringing it to a standard strength in

0 period of supporting materials. The air displaced from the equipment, saturated with vapors of alcohol, is sent to the collection tank 10. In the collection tank 10 is not carried out.

5 only mixing, but also dispersing the trapped air in water, which provides a highly developed phase interface on which the mass transfer process occurs, and, accordingly, the efficiency of the alcohol adsorption process

from exhaust air and the disposal of alcohol.

After reaching a certain concentration of alcohol in water, the resulting water-alcohol mixture is sent to collectable scrap 7 to return to the original process. After reaching the standard strength in the filters and the adsorber, the water-alcohol mixture is sent for pre-treatment of suspended particles to the pre-filter 5, and then it is processed in the adsorber 2 through the collector 3, which serves to uniformly distribute the mixture over the adsorber cross section. The water-alcohol mixture treated with activated carbon (sorting) is led through a safety screen to a fine filter 6, from where it is sent to a collection of finished products. Hydraulic unloading of coal is carried out using device 4, by supplying tap water to the device and adsorber 2 and draining the suspension of coal with water.

The proposed installation allows to mechanize the loading of the adsorbent into the adsorber, which reduces the time of simple equipment for loading the adsorbent and

improves productivity, reduces the use of manual labor and improves working conditions; carry out the separation, removal and collection of the pulverulent fraction, which reduces the time for preparing the adsorbent for use and the use of manual labor, reduces coal losses, increases the productivity of the installation by using a suspension during processing of the mixture; Dispose of alcohol from the exhaust air using

recycling circuit when filling the adsorber and filters with a water-alcohol mixture, which reduces the loss of alcohol. The formation of a circulation loop for washing the adsorbent using a piping system and the connection of the coal collector to the mixer-mixer. This reduces the preparation time of the adsorbent, reduces the laboriousness of manual operations, the loss of adsorbent and improves productivity.
