Description

one

The invention relates to the field of the alcohol industry, namely to automate the process of rectification.

Known cnoco6fj automatic control of a continuous three-column disinfection apparatus (borage, sampling and distillation colopps), which provide for the regulation of steam supply to the corresponding columns depending on the pressure in the cube of the column, loading of the rectification column depending on the mismatch of the set and current temperature of the plate plate, and the loading of the rectifier column depending on the mismatch of the set and current temperature of the plate plate of the plate plate. water in xCheflegmatorycondensers colopp.

However, in these methods, both alcohol and lutherization or the production of a nonstandard finished product according to strength are in demand.

In order to improve the efficiency of the apparatus and stabilize the selection of the finished product, the proposed method measures the level of the epuret outside the epuration column and, depending on the latter, regulates the flow of water to the reflux condenser of the brew column.

The drawing shows schematically the proposed apparatus with an automatic control system.

Continuous recycling apparatus consists of a mash, epuration and distillation columns 1, 2 and 3 with reflux condensers 4 and a compensator tank 5.

The borax column / is equipped with a pressure sensor 6 installed in the lower part of the column and connected to the regulator 7, which acts on the actuator 8 on the 1-column steam supply line. The regulator 9 changes the consumption of the mash into the column with the help of the actuator 10 depending on the temperature at the top of the column.

The regulator // changes the water supply to the reflux condenser 4 of the beer column with

using the actuator 12, depending on the level in the compensator tank, the epyration column 2 is equipped with a pressure sensor 13 installed in the bottom of the column and sends a signal to the regulator 14, which controls the actuator on the steam supply line to the column and the pressure sensor 15 in the upper part of the column, acting through the controller 16 on the supply of cooling water to the dephlegmator condenser of this column.

The distillation column 3 is equipped with a temperature sensor 17 installed in the lower part of the column and giving a pulse to the regulator 18, which acts on

filing of the epyurat using the actuator 19; a pressure sensor 20 acting through the regulator 21 on the operating mechanism 22 on the steam supply line to the column; a pressure sensor 23 acting on the cooling water iodine into the reflux condenser-condenser 4 with the aid of the controller 24 and the actuator 25.

The device is controlled as follows.

; With the increase in the consumption of the epyura, its level (margin) in the compensating tank 5 and decreases; changes the signal to the regulator llj which increases the flow of water into: dephlegmator-condenser boom column 1 using the actuator 12.

As a result, the production of petroleum distillate increases, as the condensation of vapor in the reflux condenser increases, the pressure at the top of the beer column decreases, and the pressure drop across the column increases, resulting in an increase in strain on the plates, and consequently, the temperature of the nutrient tarfch changes, causing the temperature to rise. the regulator 9, which acts on the repair mechanism 10 installed on the supply line of the mash into the column.

With some overloading of the rectifier in the column, the regulator / 4 is triggered, which affects the reduction of the supply of epyurata to the distillation column with the help of the actuator 19. The level of the epuret in the compresser tank increases and the regulator // is activated to decrease the performance of the column, therefore the temperature of the feeding plate goes down - the regulator 9 is activated to reduce the supply of the mash to the column.

The regulator 7 controls the flow rate of steam entering the production column by the pressure in its lower part. The regulator 14 stabilizes the pressure in the lower part of the epuration column.

The flow rate of cooling water in the reflux condenser in the epyration and distillation columns is measured by the appropriate regulators 16 and 24 depending on the pressure in the upper part of these columns.

The regulator 21 controls the flow rate of steam entering the distillation column by pressure in its lower part.

Subject invention

The method of automatic control of a continuous three-column disinfection apparatus (borage, enyuratio and distillation columns), which regulates the supply of steam to the corresponding columns depending on the pressure in the bottom of the column, the distillation column load, depending on the mismatch of the set and the current temperature on the control plate, and

also supplying water to the reflux condensers of the columns, characterized in that, in order to increase the efficiency of the apparatus and stabilize the selection of the finished product, the level of the epyurate upstream of the epuration column is measured and, depending on the latter, regulate the flow of water to the reflux condenser of the brew column.
