Moveable water intaking device for small and medium-sized seawater desalination system

Abstract

The invention discloses a moveable water intaking device for a small and medium-sized seawater desalination system. The moveable water intaking device for the small and medium-sized seawater desalination system comprises a reinforced concrete fixed base installed on the seabed, a glass fiber reinforced plastic prefabricated cylinder body mounted on the fixed base through a fixed foundation bolt, aplastic float cylinder arranged in the prefabricated cylinder body, an underwater water intaking pump fixed to the top of the plastic float cylinder and a water outlet hose connected with an outlet of the underwater water intaking pump. The lower part of the prefabricated cylinder body is provided with a water inlet grating, and a contamination draining hole is formed in the bottom of the prefabricated cylinder body; the plastic float cylinder and the underwater water intaking pump float up and down with a water intaking surface going up and down by arranging a fixed rail on the inner wall ofthe prefabricated cylinder body and a slide rail on the outer wall of the plastic float cylinder, and supporting legs are arranged at the bottom of the plastic float cylinder. The water intaking device is provided with few construction machines, and a non-submersible pump is used as the water intaking pump, internal equipment and facilities are arranged in a centralized mode, and the high flexibility and the reuse are realized.

Description

technical field [0001] The invention relates to a water intake device, which belongs to the field of surface sea water intake, in particular to a movable water intake device used in a small and medium-sized seawater desalination system. Background technique [0002] With the proposal of the "Island Seawater Desalination Project Implementation Plan" jointly issued by the National Development and Reform Commission and the State Oceanic Administration in December 2017, the produced water from seawater desalination will become one of the main water supply methods for water-scarce island areas in 2020. It is clearly stated in the implementation plan that within 3 to 5 years, the construction and construction of about 100 seawater desalination projects (with a construction scale of 50 to 1000m3 / d) will be promoted in Liaoning, Shandong, Zhejiang, Fujian, Hainan and other coastal cities. Upgrading and renovation to effectively alleviate the water problem of island residents and mee...

AI Technical Summary

Problems solved by technology

[0005] (1) The cylinder body of the existing water intake device mostly adopts reinforced concrete structures, and the site is highly dependent on construction machinery and tools, requiring more specifications and types of construction machinery to effectively complete the installation of the water intake device

[0006] (2) The submersible pumps are mostly used in the district water pumps supporting the existing water intake devices. This type of water pump is always immersed in highly corrosive seawater, which requires high material requirements for the pump body, and is prone to motor leakage and water inflow, which may lead to paralysis of the pump, etc. Happening

[0007] (3) The equipment and facilities of the existing water intake devices are relatively scattered, and the workload of daily operation and maintenance is large; and the devices are generally permanent facilities, with poor flexibility
