Problems solved by technology

There are many gaps between zeolite particles, and the residual water in the gaps is difficult to extract by extrusion, which affects the yield of desalinated water
In actual operation, about 15%-20% of the fresh water produced by the reaction cannot be squeezed out for use, which is a relatively large waste for the more expensive seawater desalination agent

Embodiment 1

[0034] The fabric material based on silver-containing zeolite described in Example 1 includes silver-containing zeolite and fiber fabric, and the silver-containing zeolite is adhered to the fiber fabric by coating and bonding with an inorganic binder. First, the ordinary zeolite powder and the inorganic binder are prepared into a slurry, and then coated on the fiber fabric material by the doctor blade method; after drying and solidification, the zeolite-containing fabric material is soaked in a silver nitrate solution of 0.5 moles per liter. ion exchange. Add a small amount of nitric acid dropwise to the silver nitrate solution to adjust the pH to about 5.0. Ion exchange is carried out under dark conditions, and the treatment temperature is 60 degrees. After 2 hours of exchange, replace with fresh silver nitrate solution, and exchange again. Then wash with deionized water. After drying, the silver-containing zeolite fabric material is prepared. By controlling the coating t...

Embodiment 2

[0037] Example 2 describes a fabric material based on a barium-containing zeolite comprising a barium-containing zeolite and a fiber fabric to which the barium-containing zeolite is attached. First, the surface of the fabric is modified with a silane coupling agent, and then the modified fabric is put into an organic dispersion of zeolite and heated at 90 degrees for treatment. The silanol on the surface of the zeolite reacts with the silanol on the surface of the silane coupling agent, cross-links together, and immobilizes the zeolite on the fiber fabric. Soak the fiber fabric loaded with zeolite in 1 mole per liter of barium chloride aqueous solution for 24 hours. Wash and dry with deionized water to obtain barium-containing zeolite fabric material. The amount of barium-containing zeolite accounts for more than 15% of the total amount of barium-containing zeolite and fiber fabric,

[0038] As a preferred embodiment, the barium-containing zeolite used in this example is cha...

Embodiment 3

[0040] The fabric material based on silver-containing zeolite described in Example 3 includes silver-containing zeolite and fiber fabric, and the silver-containing zeolite is attached to the fiber fabric. The silver-containing zeolite fabric material used in this example is a zeolite fabric material prepared by in-situ hydrothermal growth. Soak it in a 0.2 mole per liter silver nitrate aqueous solution with a pH value of 5.5, carry out ion exchange under dark conditions, replace the fresh silver nitrate aqueous solution four times within 24 hours, then wash it with ultrapure water and dry it to prepare Silver zeolite fabric. By controlling the reaction conditions, it is ensured that the silver-containing zeolite accounts for more than 15% of the silver-containing zeolite and the total amount of the fiber fabric,

[0041] As a preferred embodiment, the silver-containing zeolite on the fabric material prepared in this example is P-type zeolite, and the molar ratio of silicon at...

Abstract

The invention relates to a fabric material based on silver-containing zeolite, and the material comprises the silver-containing zeolite and a fiber fabric; the silver-containing zeolite is attached tothe fiber fabric, the weight of the silver-containing zeolite accounts for greater than 15% of the total weight of the silver-containing zeolite and the fiber fabric, and the molar ratio of silicon atoms to aluminum atoms in the silver-containing zeolite is 1-1.5: 1. The invention also relates to an application of the silver-containing zeolite-based fabric material in seawater desalination treatment. Seawater can be converted into drinkable fresh water after flowing through the filter column filled with the fabric. The invention has the beneficial effects that the silver-containing zeolite and the fiber fabric form a porous structure, so seawater can be automatically and uniformly mixed while flowing through the device, manual shaking is not needed, and the physical strength and time of auser are saved; fresh water remained in the fabric material can be washed down by seawater and is completely collected into drinking water, so the utilization rate is high; fresh water can be prepared and drunk at the same time without waiting for complete completion of the reaction.

Description

technical field [0001] The invention belongs to the technical field of seawater desalination, and in particular relates to a fabric material based on silver-containing zeolite and its application in seawater desalination. Background technique [0002] Seawater contains a lot of salt, and the taste is salty, bitter and astringent. Because the salt concentration is too high, its osmotic pressure is much higher than that of human cells, so drinking it directly cannot quench your thirst. If you drink seawater directly, the excess salt brought into the human body must be diluted with additional water from the body fluids before it can be excreted in the form of urine or sweat, which will cause severe dehydration and even death. Therefore, seawater must be desalinated and desalinated before it can be used for human consumption to replenish water. When humans are active at sea, a lifeboat or parachute equipment usually needs to carry seawater desalination devices to provide fresh...
