Abstract
The utility model relates to an inlet water temperature control device for a reverse osmosis device, which comprises a PLC control device, a plate heat exchanger, a temperature sensor and an electric valve. An air inlet, an air outlet, a water inlet and a water outlet are respectively arranged on the plate heat exchanger; the water outlet of the plate heat exchanger is communicated with a water inlet pipeline of the reverse osmosis device; the temperature sensor is arranged on the water outlet; the electric valve is arranged at the position of the air inlet of the plate heat exchanger; and the electric valve and the water outlet are communicated with the PLC control device. By arranging the plate heat exchanger in front of the reverse osmosis device and automatically controlling the air inlet quantity of a steam heat source on the plate heat exchanger through the PLC control device, the temperature sensor and the electric valve, the inlet water temperature control device ensures that the temperature of hot water before entering an RO film of the reverse osmosis device is kept around 25 DEG C, further improves the use efficiency of equipment and energy resources, saves production cost and has the advantages of energy conservation, emission reduction, convenience in operation and stable running.
