Detailed Description
Fig. 1 is a schematic diagram of a system for extracting deep seawater using a semi-closed large water tank 1. The semi-closed big water tank 1 is a pressure-adjustable semi-closed big water tank 1, and relates to a water conveying pipeline, a semi-closed big water tank 1, a water pump 7 and a reservoir 3, a diversion basin for extracting deep seawater is a main part for extracting deep seawater, one end of the diversion basin is connected with the other end of the water conveying pipeline leading to the deep seawater and is communicated with the reservoir (3), the semi-closed big water tank 1 is a substitute for the diversion basin, and can enable the space above the water level 13 in the semi-closed big water tank 1 in operation to be pumped into a negative pressure state by a vacuum pump 5, and the negative pressure state refers to a state lower than one atmospheric pressure or a vacuum state.
The semi-closed big water tank 1 is provided with a vacuum pump 5 for controlling the negative pressure and a controller 6 for controlling the vacuum pump to work.
The vacuum pump 5 can be selected in various ways, preferably a water ring vacuum pump, the limit vacuum degree range of which can reach 2000-4000pa, and more than two vacuum pumps are arranged to ensure the normal operation during maintenance.
The vacuum degree of the space above the water level 13 in the semi-closed large water tank 1 is maintained in the range of 0.8-0.4 atmosphere.
The water level 13 of the semi-closed large water tank 1 is controlled above the water inlet 11 of the water conveying pipeline during operation.
When the deep seawater is far from the coast, such as about one hundred seas, the diversion basin adopted in the prior art places the water inlet of the diversion basin at a position lower than the sea level to the greatest extent so as to obtain a large fall, so that the deep seawater enters the diversion basin at a higher speed under the action of the communicator, but the increase of the fall can greatly increase the construction cost and the construction difficulty of the project, the diversion basin or the weighing diversion well in the prior art is replaced by the semi-closed large water tank 1, the problem of insufficient depth of the water inlet of the diversion basin can be greatly solved, the operation change of the vacuum pump can be adjusted according to the water demand, and the semi-closed large water tank 1 is placed at the same depth as the diversion basin in the prior art, so that the huge advantages of the diversion basin can be embodied.
In normal operation, the water pump 8 continuously raises the deep seawater pumped into the semi-closed large water tank 1 to the water reservoir 3 so that the water level 13 of the semi-closed large water tank 1 is maintained substantially constant by the operation of the vacuum pump 5. The vacuum pump 5 is regulated and controlled by a controller 6. The vacuum pump 5 is installed on a solid foundation, and an air inlet pipe 501 of the vacuum pump 5 enters from the top of the semi-closed large water tank 1.
The pump 8 may be multi-stage pumped to a desired height for storage of water in the reservoir 3.
The vacuum pump 5 is installed on a solid foundation, and fig. 1 shows that an air exhaust pipeline 501 of the vacuum pump is bent at 90 degrees into the top end of the semi-closed large water tank 1 above the semi-closed large water tank 1, and a nearby reinforced concrete foundation is selected if the strength of the top end of the semi-closed large water tank 1 is insufficient.
The semi-closed large water tank 1 of the present invention may be of a metallic material construction, without excluding the use of other materials of sufficient strength and corrosion resistance.
After being pumped into the semi-closed large water tank 1 through the water delivery pipeline, the water pump 8 can pump the water entering the semi-closed large water tank 1 to the reservoir 3, and if the water entering the semi-closed large water tank 1 is the same as the water pumped to the reservoir 3, the water level 13 of the semi-closed large water tank 1 is kept unchanged. The space above the water level 13 of the semi-closed large water tank 1 becomes negative pressure under the action of the vacuum pump, and the negative pressure state can accelerate the entering speed of deep seawater of the water conveying pipeline to enable the water level 13 to rise. This increases the volume of water pumped, and more water is pumped from the semi-enclosed large tank 1 to the reservoir 3. The semi-closed large water tank 1 has the function of greatly increasing the water pumping amount and increasing the water pumping speed under the condition of the same fall or pressure difference.
In fig. 2, a substantially complete pumping system consisting of two, semi-enclosed large tanks is shown, which is the main component of another form of deep seawater pumping diversion basin, and in fig. 2, one, semi-enclosed large sub-tank 2 is added, and a connection pipe 12 and a gate valve 4 are added, and a second vacuum pump 51, an air inlet pipe 502 and a closable air gate valve 9 communicated with the atmosphere are also added. A communicating pipe 12 is arranged between the two semi-closed large water tanks, and a valve 4 which can be opened and closed is arranged on the communicating pipe 12.
The working process of the device is that when deep seawater is pumped into the semi-closed large water tank 1 through a water conveying pipeline and reaches an air inlet pipe 502 close to the top of the tank, the vacuum pump 51 is started to enable the second large water tank to be in a second state, when the vacuum degree of the semi-closed large water tank 2 is equal to that of the first large water tank 1, after the gate valve 4 of the communicating pipe 12 is opened, the two water diversion tanks are in the same vacuum degree, water in the semi-closed large water tank 1 can rapidly flow into the second large water tank 2, the water level 13 can be consistent quickly, due to the second large water tank 2, the vacuum pump 51 of the semi-closed large water tank 2 is accelerated to continue to work, and the water level 13 of the second large water tank 2 is higher than the water level 13. When the water level 13 of the first semi-closed big water tank 1 drops to be close to the mouth of the water delivery pipeline, the switch gate valve 4 of the communicating pipe 12 connecting the two semi-closed big water tanks is closed, the vacuum pump 51 of the second semi-closed big water tank 2 stops working, then the air gate valve 9 is opened to communicate the second semi-closed big water tank 2 with the atmosphere, when the atmospheric pressure acts on the second semi-closed big water tank 2, the water pump 8 is started, and the deep seawater of the second semi-closed big water tank 2 enters the water inlet pipe 81 of the water pump 8 under the atmospheric pressure and is pumped to the reservoir 3 by the water pump 8 through the water outlet pipe 82. Such a procedure can be repeated, which is more energy efficient.
Next, a water pump 7 mounted on or beside the reservoir 3 pumps the deep sea water in the reservoir 3 through its inlet pipe 71 via the water pump 7 and outlet pipe 72 to the desired deep sea water.
