Overview

The qualified raw water from the fully automatic double tube plate multi effect distilled water machine is pressurized by a multi-stage pump and enters the condenser for heat exchange. It then sequentially enters each effect preheater, and then enters the first effect evaporator where it is sprayed onto the inner wall of the heating tube through the material water distributor, causing the material water to flow in a film like manner 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.

　　Double tube plate multi effect distilled water machineThe basic requirements of the process

2.1 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.

　　2.2Double tube plate multi effect distilled water machineThe emergency incident

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