Full automatic control device and control method for wind-light complementary type seawater desalination system

Abstract

The invention discloses a full automatic control device and control method for a wind-light complementary type seawater desalination system. The device includes a low pressure pump, a seawater filter, a single-direction valve, a high pressure pump, a discharge valve, a reverse osmosis membrane assembly, a membrane assembly cleaning box, a fresh water collecting bin, a full automatic control module and a power supply module. The low pressure pump, the sea water filter, the single-direction valve, the high pressure pump, the reverse osmosis membrane assembly, the membrane assembly cleaning box and the fresh water collecting bin are connected with each other successively through water pipes. The discharge valve is connected to a pipeline between the high pressure pump and the reverse osmosis membrane assembly. The low voltage pump, the high voltage pump and the power supply module are all connected to the full automatic control module. Since the full automatic control module is connected with the low voltage pump and the high voltage pump through power leads, full automatic control of the whole wind-light complementary type seawater desalination system is realized and no manual monitoring and operation is needed. The automation degree is high. Besides, since the device is equipped with a small-capacity storage battery which is capable of relieving power supply fluctuation when necessary, the use of a large-capacity storage battery is saved, the cost is reduced and charge and discharge consumption can be reduced effectively.

Description

technical field [0001] The invention relates to the field of full-automatic control of a wind-solar complementary seawater desalination system, in particular to a full-automatic control device and a control method of a wind-solar complementary seawater desalination system with full automation, high efficiency and perfect technology. Background technique [0002] With the increasing shortage of traditional energy sources and the seriousness of environmental pollution, the sustainability of energy utilization in my country is also facing severe challenges. Both solar energy and wind energy are clean and non-polluting renewable energy, and they are complementary. Combined power generation can provide relatively stable electric energy, and its operation is safe and reliable, without fuel, pollution-free, and can be used locally without additional power transmission and transformation The equipment is easy to use and maintain, and the scale is adjustable, so it has received wides...

AI Technical Summary

Problems solved by technology

[0003] Existing seawater desalination equipment requires manual operation and inspection. When the power fluctuates, manual operation is required and the steps are cumbersome. When there is a problem with the seawater desalination device, manual inspections are required to find out the inspection, which makes the seawater desalination process inconvenient and unsafe.
