Block reagent pumping station (BRPS) is designed for mixing depressant and anti-turbulent additives in reagent tanks.
Block reagent pumping station (BRPS) is designed for mixing depressant and anti-turbulent additives in reagent tanks.
The BRPS also includes:
- filters;
- depulsators;
- technological piping, including pipeline elements;
- regulating and shut-off electric actuator fittings;
- instrumentation kit.
BRPS is made in the form of a one-story block box with dimensions of 6000x3000x3200 mm of maximum factory readiness, with engineering and technical support systems and technological equipment located in it.
BRPS consists of two rooms separated by a type 1 firewall.
- premises of pumping units;
- electrical room.
Each room has a separate entrance. The block is equipped with the necessary stairs and service areas.
BRPS is equipped with pumps for the dosing of reagents. The parameters of the pumps are presented in table 1; it is supplied complete with instrumentation and control equipment for controlling the technological process of operation, junction boxes, cable products, and control system equipment.
