Multi effect distilled water machine manufacturer for injection water

Description :

　　Basic requirements for the process of multi effect distilled water machines for injection water by manufacturers

　　Basic requirements for multi effect distillation process

　　(1) The drainage rate of multi effect distillation should not exceed 15% of water.

　　(2) Determine the intermittent or continuous operation of the multi effect filter based on the working capacity of the injection water tank.

　　(3) To ensure water quality, the system should constantly record and monitor the conductivity of the distilled liquid. The equipment port should be equipped with a manually controlled diversion valve (installed with remote control of the injection water storage tank inlet) for detecting unqualified distilled liquid, automatically diverting and draining the unqualified condensate until the distilled liquid meets the quality requirements.

　　(4) The system should operate continuously at full load or intermittently based on the liquid level of the storage tank. If the injection water distillation is in standby mode, the surface of the heat exchanger should maintain heat. Before startup and after delayed shutdown, the distilled liquid enters a synchronous pre sterilization cycle to ensure that the transported water does not contain any heat source.

　　(5) Monitor and record the conductivity of the feedwater entering the system. When unqualified water supply is detected, the control panel will sound an alarm and automatically shut down the system. Suppliers should provide automatic control valves to discharge water until the water quality is qualified.

　　(6) If the purified water supply pressure is lower than the normal distillation operation, the supplier should provide a water supply equipment package, including a water pump, base, pipeline, instrument, and control. This equipment package needs to be integrated into the control scheme and base of the injection water distillation.

　　(7) Multi effect distillation should ensure that the temperature of the distillate during operation is always not lower than 92 ℃.

　　(8) All multi effect distillation operations should be automatically controlled.

　　Emergency incident of multi effect distilled water machine manufacturer for injection water

　　Automatic shutdown in case of emergency, and automatic shutdown in case of interruption of medium and energy supply.

　　The qualified raw water from the multi effect distilled water machine manufacturer for injection water is pressurized by a multi-stage pump and enters the condenser for heat exchange. It then sequentially enters each effect preheater and is sprayed onto the inner wall of the heating tube through the material water distributor in the first effect evaporator, causing the material water to flow in a film shape inside the tube and be heated and vaporized by steam from the boiler. The secondary steam carrying water droplets generated enters the steam water separation device from the lower end of the heating tube, and the separated pure steam enters the next effect as heating steam. The raw water that has not been evaporated enters the next effect, and the above process is repeated. The pure steam generated by the final effect enters the condenser and converges with condensed water from all effects except for the first effect for cooling. After removing insoluble gases, it becomes injection water with a temperature of 92-99 ℃.

　　Multi effect distilled water machine manufacturer for injection water. The multi effect distilled water machine adopts double tube plates to prevent cross contamination of multiple materials (double tube plates or single tube plates are used according to customer requirements)

　　Raw material selection: SS316L is used for the parts and pipelines in contact with distilled water and secondary pure steam, while SS304 is used for the rest of the parts.

　　Reasonable sealing structure: The majority of the equipment adopts flange connection, evaporator and separation split structure, and PTFE sealing gasket to seal the whole machine and prevent leakage.

　　The three-stage separation method: falling film evaporation, gravity settling, and wire mesh foam removal.

　　Reasonable control of automatic discharge of qualified and unqualified distilled water: controlled by PLC using a two position three-way valve.

　　One effect liquid level control: avoids unqualified water output of the entire equipment.

　　Electrochemical polishing: high surface smoothness; Improve the corrosion resistance of stainless steel; Can polish positions that cannot be processed by mechanical polishing equipment, which is beneficial for multi effect distillation

　　The water quality of the water machine's effluent is very important.

　　Multi effect distilled water machine manufacturer for injection water. Multi effect distilled water machine saves energy: due to the use of thin-walled heat exchange tubes and advanced material water distributors, as well as the use of injection water generated by each effect evaporator as the heating source for the preheater, the entire system

　　The heat exchange rate of the device has increased by 20%. The 5-effect machine does not require cooling water in northern regions, while in southern regions, it uses a small amount of cooling water. The 6-effect machine does not require cooling water.

　　Long service life: Due to the use of large space and low-speed separation, it avoids steam friction and corrosion. Greatly extend the service life of the machine, work under the same conditions, S-shaped multi effect

　　The service life of the machine is extended by 5-6 years compared to the spiral plate multi effect machine.

　　Fully automatic welding with internal and external argon gas protection: welding pipelines and equipment cylinders to ensure welding quality.

　　Insulation layer: made of glass wool or composite silicate needle blanket, with an outer layer made of SS304 brushed board.

　　Control system: There are multiple control modes for users to choose from: manual, PLC instrument fully automatic, PLC touch screen, etc. The PLC instrument is fully automatic and can be displayed online

　　Temperature, conductivity, flow rate, pressure, etc. can be observed online through the PLC touch screen to monitor parameter changes (temperature, conductivity, flow rate, pressure, etc.) at any time

　　Understand the production status of the equipment. And can be equipped with paper or paperless recorders according to customer requirements.
