Zeolite membrane seawater desalination device

Abstract

The invention discloses a zeolite membrane seawater desalination device which comprises a sediment precipitate treatment tank. A sediment rough filtration net is fixedly connected at a position, closeto the top, inside the sediment precipitate treatment tank, the left end of the sediment rough filtration net is fixedly connected with a precipitate accumulation tank, a secondary filtering layer isfixedly connected below a deslagging passage, a filtering residue collection tank is arranged on the left side inside the sediment precipitate treatment tank and positioned on the left side of the secondary filtering layer, one end, positioned inside the sediment precipitate treatment tank, of an exhaust pipe is communicated with an air outgoing spray pipe, the middle of the right side of the sediment precipitate treatment tank is communicated with an ion separation passage, and the middle of the surface of a transmission connection plate is fixedly connected with a zeolite membrane. The invention relates to the technical field of seawater desalination. The zeolite membrane seawater desalination device achieves the objectives of avoiding sediment blocking the filtering layer, improving sediment treatment efficiency of seawater desalination and cleaning efficiency of a filtering membrane, lowering cleaning difficulty of the filtering membrane and ensuring quality of seawater separatedand desalinated by the filtering membrane.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a zeolite membrane seawater desalination device. Background technique [0002] Seawater desalination is the use of seawater desalination to produce fresh water. It is an open-source incremental technology to realize the utilization of water resources, which can increase the total amount of fresh water without being affected by time, space and climate, and can guarantee stable water supply such as drinking water for coastal residents and replenishment water for industrial boilers. [0003] The process of obtaining fresh water from sea water is called desalination. Currently used seawater desalination methods include seawater freezing method, electrodialysis method, distillation method, reverse osmosis method, and ammonium carbonate ion exchange method. At present, the application of reverse osmosis membrane method and distillation method is the mainstream in the mar...
