1. Structural form: Evaporator, Preheater and Condenser are all double tube plate design, adopting inner tube plate expansion outside welding process to avoid cross-contamination.
2. Separation device: Three-stage separation with falling film evaporation, gravity separation and spiral flow.
3. Material: SS316L is used for all parts in contact with feed water, pure steam and pure steam condensed water.
4. Thermal insulation: Evaporator and Preheater are insulated with aluminum silicate needled blanket, which has good extensibility, light weight, excellent thermal insulation and strong stability.
5. Surface treatment: Electrochemical polishing of internal and external surfaces, effectively ensuring the finish of the stainless steel surface.
6. Energy saving and consumption reduction: The evaporator and separator form a huge connecter, and the heat is fully utilized. The whole equipment can reach the maximum production capacity from the standby state in a very short time. The use of liquid level control feed water is fully utilized to achieve full energy saving and consumption reduction. Preheater 2 uses industrial steam condensate to preheat, and plays a role in saving energy.
7. Pipes as far as possible using stainless steel pipe stretching and bending directly to avoid welding. Pipes and fittings weldments using argon gas protection automatic welding (single-side welding double-sided molding process), to ensure the quality of welding, post-weld electrochemical polishing.
8. Provide endoscopic inspection photos, weld joint diagrams, pressure test and pickling passivation report and system design documents and other verification information.
9. The control system adopts HMl+PLC full-automatic control with easy operation interface. Various communication modes are available. Control system authority level: at least three levels of authority can be set.
10. Online monitoring of conductivity, temperature and flow rate and other parameters. Recorder can choose paperless recorder or paper recorder to record and print the key parameters.
11. The control system can be equipped with electronic signature, electronic records, so that the system control with audit trail function, and to meet the requirements of GAMP5 and meet the requirements of 21 CFR PART 11.
