AUTOMATED CONTROL SYSTEM FOR WATER DECONTAMINATION STATION AND METHOD OF CONTROLLING OUTPUT OF ELECTROLYSIS APPARATUS IMPLEMENTED BY SAID SYSTEM Russian patent published in 2013 - IPC C02F1/76 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to automation of water treatment and drinking water decontamination processes. The water decontamination station includes an electrolysis apparatus for producing chlorine and a distribution system consisting of multiple lines for feeding chlorine to decontamination points with a shutoff-control device in each line, which is controlled by an analyser of chlorine content in water and is configured for feedback based on the position of the shutoff element. The automated control system for the station includes a controller which controls output of the electrolysis apparatus based on total chlorine demand in all feed lines and an operator panel connected to the controller. The controller has modules for receiving input signals from analysers of chlorine content in water and shutoff-control devices, a program-logic unit which enables analysis of input information, detection of malfunctions in the shutoff-control devices, emergency situations and generation of control signals, modules for preparing output signals connected to control circuits for actuating mechanisms of the shutoff-control devices, the power supply unit of the electrolysis cell and drives of dosing pumps of the electrolysis apparatus. The method of controlling output of the electrolysis apparatus based on the total chlorine demand at n water decontamination points with independent feed lines involves analysing chlorine content and determining demand thereof at each water decontamination point, determining total chlorine demand at all water decontamination points and determining operating power of the electrolysis apparatus based on the value of total chlorine demand using a two-scale method.

EFFECT: enabling automatic control of the chlorine production process in accordance with thereof in more than one water decontamination line, as well as faster control and reaction of the system to changing parameters.
