Technical field
The utility model relates to a kind of pressurizing device, and particularly a kind of wind power direct that is applicable to reverse osmosis seawater desalting drives ram pump formula pressurizing device, belongs to new forms of energy and energy-conserving and environment-protective fields.
Background technology
At present, then the Wind-powered Desalination main path utilizes electric energy to drive the high pressure electric pump desalination by reverse osmosis processing, i.e. wind-powered electricity generation reverse osmosis unit is carried out in the water pressurization for utilizing wind power generating set first wind energy transformation to be electric energy.There is following problem in this device: (1) utilizes wind energy transformation to be electric energy, then is converted into pressure energy, and energy conversion process is more, and capacity usage ratio is not high; (2) impact of wind-engaging fluctuation, the less stable of wind-powered electricity generation output, larger for increasing the capacity such as the stable store battery that adopts, invertor, one-time investment is expensive; (3) one-time investment of aerogenerator own is larger.
The utility model content
The purpose of this utility model is to solve the problems referred to above that present wind energy reverse osmosis seawater desalting exists, and a kind of wind-force pressurizing device that is applicable to reverse osmosis seawater desalting is provided.
The technical scheme that the utility model is taked is:
A kind of wind-force pressurizing device that is applicable to reverse osmosis seawater desalting comprises fan blade, and fan blade connects tooth sector, and tooth sector is connected with the ram pump of reverse osmosis system by transmission shaft, and ram pump is controlled seawater and entered reverse osmosis membrane assembly.
Described reverse osmosis system comprises reverse osmosis membrane assembly, reverse osmosis membrane assembly connects ram pump, ram pump is fixed on the tower bar, ram pump with higher than the startup water tank of its position be connected the pretreatment filters of its position and be connected, pretreatment filters connects energy converter by reverse checkvalve, and energy converter communicates with seawater.
Described startup water tank is provided with intake valve, and the reverse osmosis membrane assembly water outlet is established pressure maintaining valve.
Be provided with energy storage, tensimeter between described reverse osmosis membrane assembly, ram pump.
Described reverse osmosis membrane assembly is connected with energy converter by the strong brine return line.
Described ram pump is fixed in following 2-3 rice, top of tower bar.
The startup water tank is installed by section at the tower masthead, fill with in advance clean seawater, the rotation of wind drive fan blade, drive vertical transmission shaft through tooth sector and rotate, transmission shaft is connected with ram pump by shaft coupling, and the ram pump running is to pretreated seawater pressurization, when beginning to start, at first utilize to start the seawater injection ram pump pressurization that prestores in water tank, after steady running, provide injected water by energy converter.Seawater after pressurization enters reverse osmosis membrane and filters, and installs energy storage additional on the connecting pipeline of ram pump and reverse osmosis membrane assembly, is used for accumulation of energy and the unstable pressure surge that causes of buffering wind-force.Strong brine (containing higher pressure energy) through reverse osmosis membrane pressurizes to the former water of seawater through energy converter again, the former water of seawater after pressurization enters pretreatment filters, seawater is carried out just considering, pretreated seawater is used for replenishing the water yield of losing when the startup water tank begins to start on the one hand, becomes a mandarin for ram pump provides on the other hand.
This device ram pump is fixed in the following 2-3 rice of tower masthead, namely considers the restriction of power transmission distance, and the transmission distance is longer, and power loss is larger, takes into account again the lift that the power of the upper water in bottom can reach.
This device starts water tank and is installed on tower masthead section, startup current when being mainly used in providing system to change running status over to by halted state, because when beginning to start, the energy converter of bottom is running not, can not provide and become a mandarin, and the suction journey of ram pump is less, generally can not drive the pretreatment filters operation.In case system changes normal operation over to, energy converter can provide and become a mandarin and power, makes the former water of seawater by pretreatment filters, and for ram pump provides flow, unnecessary seawater can enter the startup water tank.It is closed starting water tank, and top is installed into air valve, can only pass in and out air, so automatically stops injecting after filling with water.
This device energy converter is installed on the bottom, is used for converting the pressure complementary energy of strong brine to setting-out kinetic energy again, to the former water pressurization of seawater, makes the former water of seawater enter pretreatment filters and carries out pre-treatment.Make to enter energy converter and get the flow that the strong brine flow is slightly larger than provides the former water of pressurised seawater, in order to replenish the water yield that starts water tank and the water loss in whole flow process.
This device is equipped with energy storage on the export pipeline of ram pump, the stability of the hydraulic pressure of increasing export, the work-ing life of prolongation reverse osmosis membrane assembly.
The rotation of this device fan blade drives ram pump and produces high pressure water after gear turns to, under the wind speed of 3.5～10.8m/s, the outlet hydraulic pressure of generation is 5～7MPa, satisfies the requirement of follow-up reverse osmosis unit pressure.
The utility model device utilizes wind energy to make the fan blade rotation, drives ram pump and rotate after gear turns to, and to pretreated seawater pressurization, carries out desalination by reverse osmosis and processes.Be the former water pressurization of seawater by the strong brine after reverse osmosis membrane assembly by energy converter, the former water of the seawater after pressurization starts water tank through offering ram pump after pretreatment filters and injecting.This device drives high pressure electric pump pressurizing device than traditional wind-power electricity generation, has reduced the conversion number of times of energy, and capacity usage ratio is high; Operation is simple, energy-conserving and environment-protective, and have stable performance, the characteristics such as one-time investment is little, and cost is low.
