NLD spiral multi effect distilled water machine

NLDWorking principle of internal spiral multi effect distilled water machine
The injection water preparation system is a key GMP system. It is a key equipment in the current application of injection water preparation systems. Adopting high temperature and high pressure operation to ensure stable production of injection water without heat source. The distilled water produced by the multi effect distilled water machine meets the requirements for injection water in the current United States Pharmacopoeia, European Pharmacopoeia, Japanese Pharmacopoeia, and Chinese Pharmacopoeia.

NLDInternal spiral multi effect distilled water machineTechnical Features

·The heat exchange tubes are made of high-quality seamless tubes: seamless tubes have better strength and durability, ensuring that they remain in good condition during processing, welding, expansion and contraction during operation, and preventing any industrial steam, raw water and cooling water from leaking into the clean distilled water and secondary steam side.

·3D bend pipe: Use stainless steel pipes as much as possible to directly stretch the bend pipe on the pipeline, avoiding welding.

·Use automatic welding: For the connection between pipelines and parts, use automatic argon gas protection trajectory welding as much as possible to ensure welding quality.

·Insulation: The evaporator and preheater are both insulated with mineral wool insulation layer that is chlorine free and asbestos free, and wrapped with stainless steel cladding.

·Three stage separation device: The raw water entering the equipment undergoes three-stage separation through falling liquid film evaporation, gravity separation, and special separation device.

·Electrochemical polishing: Electrochemical polishing of stainless steel surface to ensure the quality of production injection water and improve the service life of equipment.

·Double tube plate design: The external preheater, condenser, and high-efficiency evaporator are all designed with double tube plates, which comply with cGMP requirements and effectively eliminate the possibility of low hygiene level medium pollution in the system.

·Only economical pre-treatment of raw water is required: no expensive purified water equipment is needed, and the raw water only needs deionized water or reverse osmosis water with a conductivity of less than 5 μ S/cm.

·Economic energy saving: Due to the gradual utilization of secondary steam in various effects, the utilization rate of industrial steam is very high, which has a significant energy-saving effect. As the number of evaporator efficiencies increases, the energy-saving effect becomes more pronounced. At the same time, the amount of cooling water also decreases significantly with the increase of efficiency.

·Structural material: The pressure vessel body and pipeline in contact with distilled water and secondary pure steam are made of 316L, and the sealing material is PTFE. Other materials include the rack made of 304 material.
