Problems solved by technology
This multi-stage flash seawater desalination system has the following problems: 1. It is necessary to vacuumize the flash chamber of each stage to meet the different pressure requirements in each stage of flash chamber, which requires each flash chamber to be equipped with One vacuum pump increases the cost of equipment and makes the system too bulky; 2. Driving each vacuum pump will consume more energy, and the use of electric heaters will also consume more electric energy

Embodiment Construction
[0013] see figure 1 , the present invention has a supergravity machine 1 and a flash chamber 3, and the interior of the supergravity machine 1 is coaxially sleeved with a vacuum chamber 2, a flash chamber 3 and a fresh water tank 4 sequentially from the outside to the inside. A seawater storage chamber 15 and a fresh water storage chamber 16 are arranged at the bottom of the vacuum chamber 2 . The flash chamber 3 is in the shape of a cylinder, the upper half in the flash chamber 3 is a condensation area, the lower half is an evaporation area, and the top surface of the flash chamber 3 is an open structure. The flash chamber 3 is arranged in the middle of the vacuum chamber 2 where a vacuum environment can be formed inside the vacuum chamber 2 . The bottom of the flash chamber 3 communicates with the seawater storage chamber 15 through a conduit, and a valve is installed on the conduit. A cylindrical fresh water tank 4 is arranged in the condensation area of the upper part ...

The invention discloses a supergravity room temperature nested seawater desalination system. The interior of the supergravity machine is coaxially sleeved with a vacuum chamber, a flash chamber and a fresh water tank sequentially from the outside to the inside. Fixed connection, the bottom is connected to the motor, the seawater storage room is connected to the seawater main tank outside the supergravity machine through the concentrated seawater outlet pipe, there is a gap between the edge of the vacuum chamber top cover and the top of the vacuum chamber, and a water pump is installed in the seawater main tank , the water pump is connected to the entrance of the condensing pipe, the condensing pipe passes through the top opening of the supergravity machine, goes down through the top cover of the vacuum chamber, passes through the top opening of the fresh water tank, and opens from the top surface of the fresh water tank after rotating inside the fresh water tank Stretch upwards and return to the seawater main tank; the seawater in the seawater main tank enters the evaporation area in the lower part of the flash chamber through the seawater pipeline; a supergravity machine is used to generate a vacuum environment to improve the pressure in the flash chamber, and the structure is compact.
Description
technical field [0001] The invention relates to the fields of chemical industry and energy, in particular to a seawater desalination system, which uses supergravity to create a vacuum environment to improve the pressure in the flash chamber of the system. Background technique [0002] Seawater desalination technology includes low-temperature multi-effect seawater desalination technology, reverse osmosis technology, multi-stage flash seawater desalination technology, etc. Among them, the disadvantage of the low-temperature multi-effect seawater desalination technology is that the volume of the equipment is relatively large, which virtually increases the investment in the equipment. The reverse osmosis membrane, high-pressure pump and energy recovery device in reverse osmosis technology need to be replaced regularly, which has the problems of short membrane life and pollution. The disadvantages of multi-stage flash seawater desalination technology are rapid equipment corrosio...
