Description
Technical field
The present invention relates to the sea water desaltination field, a kind of specifically intelligent sea water distiling plant.
Background technology
Along with the growth of world population and the deterioration of environment, Freshwater resources are more and more in short supply, and increasing population faces the water crisis.Though China's Freshwater resources total amount is huge, skewness, the fresh water amount is less per capita; A lot of cities face the water crisis; Therefore, developing new fresh water sources has become a new problem, and sea water desaltination then provides new solution route for the water in coastal cities.
Method for desalting seawater commonly used has two kinds.A kind of reverse osmosis method that is called.Usually, strong solution can absorb the moisture in the outside dilute solution, can draw in the soil the water like plant root.Conversely, want to come out the moisture penetration in the strong solution, must plus high-pressure.Under the effect of this high pressure outside, penetrating the method for fresh water in the seawater, is exactly reverse osmosis method.Plus high-pressure is directly proportional with the saltiness of seawater.General reverse osmosis method sea water desaltination will be added to 80 normal atmosphere.Therefore, the container dimensional of r-o-can not be too big, and not so, the intensity of reverse osmosis membrane and container all is a problem.So reverse osmosis method is only applicable to the on a small scale brackish water desalination of sea water desaltination and hinterland of island, because the saltiness of brackish water low more than seawater.Another kind is called distillation method.The principle of this method extremely is similar to boiling water in the family, is placed on seawater in the kettle boiledly, just has on the pot lid and condenses zero(ppm) water, Here it is desalination water.
Because the distillation ratio juris is simple, is to use the earliest, also is to use method the most widely.In the prior art, the device that carries out sea water desaltination with distillation method is a lot, no matter is to adopt electrically heated or steam heating all to need the discharging of MC seawater, has taken manpower.
Summary of the invention
For solving the problem that needs the discharging of MC seawater when distillation method is carried out sea water desaltination, the invention provides a kind of intelligent sea water distiling plant.
The present invention solves the problems of the technologies described above the technical scheme of employing to be: a kind of intelligent sea water distiling plant, comprise sealed condensating device, tank, electric heat-generating disc, water pump, bracing frame and PLC system, and described sealed condensating device is the spheric transparent vessel; Its top is provided with water inlet pipe; The mouth of pipe that water inlet pipe is positioned at the sealed condensating device is horn-like, and tank is arranged in the sealed condensating device, and is positioned at the mouth of pipe below of water inlet pipe; Heat-generating disc is arranged on the below of tank; The bottom of tank is provided with water shoot, and the bottom of sealed condensating device is provided with the fresh water rising pipe of band diaphragm valve II, and described water inlet pipe, fresh water rising pipe and water shoot are all fixed through bracing frame; Described water inlet pipe is provided with water-in I and the funnel shaped water-in II that is connected with water pump, is respectively equipped with SV I and diaphragm valve I on water-in I and the water-in II; Described water shoot is provided with water port I and water port II, is respectively equipped with diaphragm valve III and SV II on water port I and the water port II; Be provided with liquid level sensor I and liquid level sensor II in the described tank; Liquid level sensor I and liquid level sensor II all are connected with the signal input part of the PLC system of peripheral hardware, and the signal output part of PLC system is connected with the water pump control device with the unit of SV I, SV II, electric heat-generating disc respectively.
Among the present invention, the water-in II be shaped as doline, be convenient to manual work and pour into seawater.
The present invention has two kinds of mode of operation; When electricity was arranged, through electric heating plate distillation seawater, the effect of liquid level sensor I and liquid level sensor II was that the seawater canned data in the tank is sent in the PLC system of peripheral hardware; The PLC system is according to the work of this signal control SV I, SV II and electric heat-generating disc; Add hot sea water and produce water vapour, water vapor condensation is a fresh water, discharges from the fresh water rising pipe; When outage, utilize sunlight spontaneous evaporation seawater, the artificial discharging of controlling seawater in the tank through diaphragm valve I and diaphragm valve III.
Beneficial effect: the present invention is equal ability works better when having electricity to supply with no electric energy; And when electricity was arranged, the work through PLC system control SV I, SV II and electric heat-generating disc realized carrying out automatically of sea water desaltination; Reduce manpower, improved working efficiency.The present invention is simple in structure, and is easy and simple to handle, and the fresh water that is particularly useful for family or drilling unit, oceangoing vessel replenishes.
