SELECTION OF CONTROL suspension from the carbonation COLUMNS

摘要

The invention relates to control systems and separating the liquid phase suspensions in a column-type apparatus, and is aimed at increasing the stability of the slurry carbonization selection column; This object is achieved in that the control system selection slurry from the carbonization column soda ash ammonia method in the precipitation unit operation comprising a gas-liquid medium temperature sensor at the top of the column and the regulator, wherein the system is provided with a pressure sensor in the common manifold suspension and an automatic control unit wherein effects on regulator performed according to the algorithm:; Y = Y ₀ + K ₁ · (T -T _{backsidetech)} -K ₂ · P; where V - the current position of the regulatory body,%;; At ₀ - the initial position of the regulatory body,%;; K ₁ - transform coefficient signals of temperature sensors, ;; T _back - set temperature gas-liquid medium at the top of column, K;; _Tech T - current temperature of the gas-liquid environment in the upper portion of the column, K;; To ₂ - pressure sensor conversion factor, ;; P - pressure in the common manifold suspensions, Pa.; The control system of the extraction slurry carbonization columns can improve reliability of the whole control system and to provide high static and dynamic accuracy maintain selection slurry. 1 Fig.
