Embodiment 1

[0040] It is composed of a gas-liquid mixer 4, a mineralization tower 9 and an ups and downs chamber 14. The gas-liquid mixer 4 uses carbon dioxide pipeline exposure to strengthen the mineralization of seawater desalination. The mineralization tower 9 fully reacts carbon dioxide and calcite filler to improve seawater desalination. For the mineralization of water, the ups and downs chamber 14 dissolves unreacted carbon dioxide, increases the oxygen content, enhances the pH value, and enhances the safety of desalinated water.

[0041] The seawater desalinated water after sedimentation and purification in the seawater sedimentation tank to remove impurities in the seawater is transported to the gas-liquid mixer 4 through the delivery pipeline, and the port of the delivery pipeline is connected with the inlet end of the water inlet pipe 1 of the gas-liquid mixer 4, and then The outlet end of the water pipe 1 is connected to the inlet end of the air-water delivery pipe 17, and the a...

Embodiment 2

[0044] The upper end of the gas-liquid mixer 4 is fixedly provided with the end of the mixed gas-water delivery pipe 23, and the end of the mixed gas-water delivery pipe 23 is inserted into the upper end of the gas-liquid mixer 4, and the port portion of the mixed gas-water delivery pipe 23 is fixedly arranged Damper 20, seals the port portion of mixed gas-water delivery pipe 23, the port portion of mixed gas-water delivery pipe 23 is fixedly provided with the upper end of central shaft 21, and the central shaft 21 upper end is inserted in the port portion of mixed gas-water delivery pipe 23, and the center The upper end of the shaft 21 is fixedly connected with the blocking plate 20 and the rotating locking groove 19, and the port portion of the mixed gas-water delivery pipe 23 is equidistantly provided with water inlet holes 24, and the desalinated sea water mixed by the gas-liquid mixer 4 passes through the water inlet The hole 24 enters the mixed gas-water delivery pipe 23,...

Embodiment 3

[0047] The gas-liquid mixed by the gas-liquid mixer 4 is input to the mineralization tower 9 for mineralization. The mineralization tower 9 is barrel-shaped as a whole, and the mineralization tower 9 is made of metal material or plastic material. The mineralization tower 9 is distributed by the mixed gas-liquid Chamber 25, water separation layer 7 and packing layer 8, mineralization tower base 5 is set at the bottom of mineralization tower 9, mineralization tower base 5 supports mineralization tower 9, and the mixed gas-water delivery pipe 23 of gas-liquid mixer 4 outputs The end is connected with the input end of the gas-liquid delivery pipe 3, the output end of the gas-liquid delivery pipe 3 is connected with the mineralization tower water inlet pipe 6 at the bottom of the mineralization tower 9, and the mineralization tower water inlet pipe 6 is connected with the mineralization tower 9 bottom The mixed gas-liquid distribution chamber 25 is connected, and the mixed gas-liqui...

Abstract

The invention relates to a desalinated seawater mineralization system and a manufacturing method for desalinated seawater mineralization. The system of the invention is composed of a gas-liquid mixer (4), a mineralization tower (9) and a fluctuation chamber (14). The gas-liquid mixer (4) reinforces desalinated seawater mineralization by the nitrogen dioxide pipeline aeration mode. The mineralization tower (9) enables carbon dioxide and a calcite filler to fully react so as to enhance desalinated seawater mineralization. The fluctuation chamber (14) enables unreacted carbon dioxide to be dissolved out so as to increase oxygen content, raise pH value and enhance safety of desalinated seawater. The gas-liquid mixer (4) is composed of a main body of the gas-liquid mixer (4), a water through hole (18), a rotary locking groove (19), a separation blade (20), a center shaft (21), a water inlet opening (24) and a rotary wheel plate (22). The system has a reasonable structure, is scientifically designed, is convenient to use, is simple to manufacture, and solves disadvantages of a traditional mineralization device. By the system, mineralization effect of desalinated seawater is raised, and mineralization time of desalinated seawater is shortened.

Description

technical field [0001] The invention relates to a seawater desalination water mineralization device, in particular to a seawater desalination water mineralization system and a preparation method for seawater desalination water mineralization. Background technique [0002] my country is a country that lacks fresh water resources, with low per capita water resources and uneven distribution in time and space. In recent years, my country's seawater desalination industry has encountered prominent problems such as overcapacity and idle equipment. Excessive production capacity growth, high production costs, and insufficient market demand are the direct causes of overcapacity. Policy support focused on investment and production has exacerbated the imbalance between supply and demand, which is not conducive to solving the problem of overcapacity. In recent years, seawater desalination has developed rapidly around the world and has become an important water source for many water-scar...
