Description

Technical Field

[0001] The utility model relates to the technical field of fluorine removal, in particular to a high-efficiency drinking water fluorine removal device. Background Art

[0002] Fluoride poisoning is one of the common endemic diseases in the world, especially in rural areas that rely on groundwater for drinking water. The main symptoms of fluoride poisoning are dental fluorosis and skeletal fluorosis. my country's drinking water hygiene standards stipulate that the fluoride content in drinking water should not exceed 110 mgPL. When the fluoride content in drinking water is 15-110 mgPL, it is necessary for the human body and can prevent dental and bone diseases. However, when the fluoride concentration in drinking water is greater than 115 mgPL, it will have a negative impact on the human body. The main methods for removing fluoride from groundwater include: 1. Adsorption method, 2. Flocculation precipitation method, 3. Electrochemical method, 4. Membrane filtration method, and 5. Chemical precipitation method.

[0003] In the prior art, activated alumina adsorption is mostly used for defluoridation of drinking water. This method can effectively remove fluoride ions in water, and also has a certain removal effect on other harmful ions such as iron, manganese, heavy metals, ammonia nitrogen, and turbidity. The filter material can be regenerated repeatedly. However, when using the activated alumina adsorption method, the pH value of the raw water needs to be adjusted. The pH value must be controlled at 6.5 to exert the effect of activated alumina. The constant change in the pH value of the raw water may cause unstable operation of the treatment device. In addition, activated alumina will release a large amount of aluminum ions when the pH of the raw water is weakly acidic, which may lead to excessive aluminum. Aluminum poisoning can damage the human nervous system. Utility Model Content

The driving gear drives the driven gear to rotate, and the driven gear drives the rotating shaft and stirring rod to rotate. The stirring rod stirs the water inside the device barrel, which increases the adsorption speed of water and alumina and further improves the defluorination efficiency.

[0011] 2. The PH detection device detects the PH value of the water inside the device barrel. When the PH value in the device barrel is low, the PH detection device controls the electromagnetic valve on the alkaline adjustment tube to open, allowing alkaline solution to flow in.

The PH value of the solution in the device barrel is kept stable through the acidic adjustment tube, the alkaline adjustment tube and the PH detection device, so that the activated alumina can stably remove fluoride, thereby improving the effect of fluoride removal in water.
