Description

All-weather intelligent desalination device Technical Field The disclosure relates to the technical field of sea water desalination, in particular to an all-weather intelligent desalination device. Background With the increase of population and the aggravation of environmental pollution, the shortage of fresh water resources becomes one of the important threats affecting the sustainable development of society, about 11 hundred million people worldwide are affected by serious shortage of fresh water, and development of efficient water resource purification technology is urgent, and in the past decades, people try to obtain fresh water from sea water through various methods, and the technology is collectively called sea water desalination technology. The current main-stream seawater desalination equipment is based on a reverse osmosis method, seawater sequentially needs to go through a pretreatment system, a reverse osmosis system, a post-treatment system and the like from a water inlet to a water outlet, wherein the water delivery needs to consume a large amount of energy, and a water suction pump, a high-pressure pump and the like are used as water transmission components to be supplied with electric power, and generally mainly depend on the electric power supply of fossil energy combustion to cause environmental pollution. The pretreatment system is a plurality of filters with different precision, the entered seawater is primarily filtered so as to avoid damage to the reverse osmosis membrane caused by a large amount of impurities, the reverse osmosis system is a high-pressure pump, a reverse osmosis membrane, an energy recovery device and the like, the high-pressure pump provides high pressure for the seawater and helps the seawater to pass through the reverse osmosis membrane in a reverse concentration gradient, the energy recovery device recovers energy from the high-pressure seawater for recycling, the post-treatment system is a water quality detection, PH adjustment and disinfection and sterilization device, and the water quality detection, PH adjustment and disinfection and sterilization device are used for carrying out water quality detection on the water passing through the reverse osmosis membrane, and the PH is adjusted by adding a reagent so as to meet the drinking water requirement.
