Process flow
The whole ultrapure water purification system can achieve the automatic operation capability after being debugged normally, and provides the functions of fault and abnormity alarming and self-monitoring. The pure water system starts from a raw water tank water inlet pipe and ends at a position 1m away from a terminal filter water outlet pipe. Including all process equipment and connecting piping, valves, plumbing within the boundary, as well as instrumentation and control systems, electrical systems for the process equipment.
Main equipment technological process
Municipal tap water → raw water tank → raw water pump → multimedia filter → activated carbon filter → scale inhibitor → cartridge filter → first-stage high-pressure pump → first-stage reverse osmosis device → first-stage RO water tank → PH adjustment → second-stage high-pressure pump → second-stage reverse osmosis device → second-stage RO water tank → EDI water supply pump → ultraviolet sterilizer → ultrafilter → EDI device → ultrapure water tank → ultrapure water pump → TOC remover → polishing mixed bed → terminal filter → water consumption point.
Cleaning process of chemical cleaning equipment
Cleaning water tank → cleaning pump → cleaning filter → RO/EDI
Description of the control System
The pretreatment part, the reverse osmosis part and the EDI part of the whole system run automatically and are controlled by the control system in the whole process. Under the condition of normal operation of the equipment, the automatic operation level can be achieved, and meanwhile, the functions of manual operation and manual control can also be realized. The logic principle of interlocking control is adopted for each control point in the system, and the operation or the stop of the single equipment or the single action point is monitored by a plurality of parts to ensure the stability of the system.
Reverse osmosis system control
The system adopts an electric cabinet to complete control. The operation or standby of the reverse osmosis device is mainly realized by controlling the starting or stopping of the high-pressure pump, and the starting or stopping of the high-pressure pump is determined by the liquid level change of the water tank. In the system, the operation of the reverse osmosis device can be controlled by the liquid level change of the water tank.
Conversely, when the liquid level in the water tank goes from high to low, the reverse osmosis is put into operation in reverse order at the same time. By adopting the control mode, not only can the water be saved, but also the cost can be saved, because the running cost of the reverse osmosis is mainly from the power consumption of the high-pressure pump.
Control of EDI system
The EDI system is designed as an automatic control system and is automatically controlled by a PLC, and meanwhile, semi-automatic and manual operation, debugging and maintenance can be carried out on the equipment.
EDI systems are relatively expensive devices in the system, and therefore, need to be relatively comprehensive and safe in terms of automation and system configuration. The water pump and the power supply are connected with pressure and flow signals of all parts together to complete the operation of the EDI system together, so that when a problem occurs in a certain link, the system can alarm and stop in time, and the damage to the system, which cannot be repaired, is prevented.
Aiming at protecting the convenient chain, the main performance is as follows:
when the power supply fails, the operation and the alarm are stopped, and a single power supply is adopted by a single membrane block;
when the flow of the concentrated water is low, the operation is stopped and the alarm is given;
when the discharge amount of the concentrated water is low, the operation is stopped and the alarm is given;
when the resistivity of the pure water is low, alarming is carried out, and produced water is discharged or backflow is carried out; (configuration according to actual conditions)
When the water inlet conductivity is high, alarming is carried out, and produced water is discharged or reflows; (configuration according to actual conditions)
