Problems solved by technology

The membrane will be polluted due to the accumulation of suspended solids, colloidal substances and soluble organic polymers in the water on the surface of the membrane; microorganisms and bacteria will cause the membrane to be eroded; the residues of microorganisms and bacteria will also be precipitated in the form of solids, which will deteriorate the performance of the membrane. Deterioration; deterioration of water temperature, pH value, residual chlorine content, pressure and other parameters will cause hydrolysis and oxidation of the membrane; changes in the membrane structure caused by solutes will also lead to a decrease in the water permeability of the membrane
[0008] The process of seawater pretreatment by reverse osmosis membrane seawater desalination is relatively complicated

Embodiment Construction

[0048] 1. Fiber cloth block

[0049] 1. The reverse osmosis membrane is the core in reverse osmosis seawater desalination. Similarly, the fiber cloth 4 in the present invention is also very critical. The fiber cloth piece 4 is deformed by pressure to form a permeable layer similar to a membrane. The reason why this kind of permeable layer can operate under low pressure (0.5 ~ 1.5MPa) and high flow rate (30 ~ 180m 3 / h single tank) under the condition of obtaining a desalination rate higher than 95%, because:

[0050] ① The filter medium of the fiber cloth block 4 is quilted by a filter cloth of polymer synthetic fiber, and the filter cloth is woven by warp yarns and weft yarns. The filter medium deforms its warp, weft and thickness under heavy pressure, resulting in an increase in the specific surface area of ​​the warp and weft. After the fiber cloth piece 4 is compacted, a filter cake is formed, and the density of the filter cake becomes larger, and there are pores betwee...

Abstract

A water treater with fibrous cloth for desalinating seawater is composed of a cylindrical main container, upper and lower screen plates, a fibrous cloth, inlet and outlet valves, upper and lower hydraulic cylinders and their rods, propeller, stirring axle and frequency variable speed adjustable motor. When said fibrous cloth is pressurized, it can become a percolating film for desalinating seawater.

Description

technical field [0001] The invention relates to a water processor, in particular to a fiber cloth seawater desalination processor. Background technique [0002] Water is the source of life, the source of development, the lifeblood of social and economic development, and a precious and irreplaceable natural resource for human beings. Water shortage is a worldwide problem and has become a bottleneck restricting social progress and economic development. With the continuous development of the economy and the continuous improvement of people's living standards, the demand for water is also increasing, and the requirements for water quality are also increasing; and the shortage of water resources, the uneven distribution of time and space, and the excessive Limited mining, unrestrained waste, and random pollution have made the already tense contradiction between supply and demand of water resources more acute. Therefore, solving the contradiction between supply and demand of wat...
