AUTOMATED SYSTEM FOR MONITORING AND CONTROL OF PHYSICAL AND CHEMICAL PROCESSES COOLING TOWERS

摘要

The invention relates to a power system and is designed to determine the optimal water-chemical mode of cooling towers evaporative type.; The purpose of this utility model is to expand the functionality of the automated monitoring and control of cooling tower operation mode by providing a physical and chemical analysis of the composition of the circulating water.; The technical result is reached by that in an automated system for monitoring and control of physical and chemical tower processes, comprising a central computer connected to the microprocessor-converter connected to the block output signals to the actuators, first detecting circulating water temperature set in the circulation water supply system watering nozzle in a cooling tower, a second circulation water temperature sensor installed at the outlet of the cooling tower, the circulating water flow sensor, installed in the cooling tower blowdown system connected to the outlet of the cooling tower, the circulating water outlet system in the turbine condenser connected to forebays tower through a circulation pump, additional water supply system of the cooling tower coupled with forebays cooling tower chemicals supply system connected to forebays tower via a pump -dozator, with a central computer through programs in real-time packet adjusts cooling tower operation and computer programs allow for geometrically s parameters concrete cooling tower and a predetermined hydraulic load on a cooling tower, according to the proposed utility model, and is further introduced a first sensor bi Conductometrs-salimeter installed in the system drain circulating water into the turbine condenser, the second sensor bi Conductometrs-salimeter installed in make-up water supply system to the cooling tower , a water level sensor mounted in forebays cooling tower, and the instrument panel sensors, the outputs of all of said sensors are connected to respective Rin rows instrument sensor panel, whose output is connected to microprocessor-converter, the computer program further take into account the concentration of impurities in the water, concentration of chemicals, deposition anions of weak acids, calcium precipitation, water level, corrosion of the iron, copper corrosion, microbiological fouling and allow automatically save annual, monthly, daily values ​​of all of these systems, analyzing them in a graphical or numerical value. 1 yl.
