A horizontal filter device for seawater desalination

Abstract

The invention provides a horizontal type filter device for sea water desalination. The horizontal type filter device is provided with a tank, a first end socket and a second end socket. Through the horizontal type filter device for sea water desalination, the modular design of a filter structure is realized, the on-site mounting is relatively convenient and quick, a backwashing siphon structure and an improved air distribution structure are realized, the backwashing flow rate is automatically increased within the overall length scope of the barrel and filtering materials within the overall length scope of the barrel are uniformly stirred and overturned, and the problem of insufficient backwashing caused by the high-flowing surface of a horizontal type filter is solved. The invention also discloses a calculating method for calculating the physical dimension of a backwashing discharging pipe opening. The horizontal type filter device for sea water desalination has the advantages of high effluent quality, high dirt-intercepting capacity, large flowing surface area, seawater corrosion resistance, uniform air distribution and backwashing, easiness in operation, small occupying area, and the like; the horizontal type filter device meets the requirement of large-scale seawater desalination practical production and is especially suitablefor a large seawater desalination project; the horizontal type filter device has obvious economic benefits and social benefits.

Description

technical field [0001] The invention relates to a horizontal filter device for seawater desalination, which belongs to the field of machinery. Background technique [0002] With the increase of the population and the improvement of the quality of life, the human demand for fresh water resources is increasing day by day. However, due to the lack of fresh water resources and the depletion of pollution, facing double pressures, human beings have turned their attention to the vast ocean for seawater desalination. [0003] Filter is one of the important components of seawater desalination pretreatment. At present, the typical filters used in the field of seawater desalination are generally vertical filters. The vertical filter has a small processing capacity and a small surface filter interception capacity, which cannot meet the needs of large and medium-sized seawater desalination. Good economy and other industrial needs. Taking the 100,000 tons / day seawater desalination plant...

AI Technical Summary

Problems solved by technology

Horizontal filters require a large flow of backwash water. Due to the unreasonable design of backwash air distribution and water distribution structures, conventional horizontal filters have poor backwash effects and cannot adapt to the long-term and stable production requirements of seawater desalination, which in turn affects subsequent operations. Production capacity of reverse osmosis desalination
