Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a fluorine removal device for fluorine-containing wastewater. Background Art

[0002] Fluorine is one of the essential trace elements for the human body that is widely present in nature. When humans consume too much or too little, it will affect their health. With the rapid development of modern industry, fluorine pollution in water bodies is becoming increasingly serious, posing a serious threat to human safety. As we all know, the adsorption method uses an adsorption filter element to adsorb fluorine in fluoride-containing wastewater. It is a relatively economical and efficient fluoride removal method that can effectively treat heavy metals, non-metallic ions and organic pollution. The current device structure for fluoride removal using the adsorption method is relatively complex. At normal temperatures, the adsorption efficiency of the adsorption filter element is not high, and it is also inconvenient for operators to replace the adsorption filter element. Therefore, the existing Chinese patent with authorization announcement number CN218709323U discloses a fluorine removal device for fluoride-containing wastewater, including a heating tank and a tank cover that is detachably arranged on the top of the heating tank. The bottom of the tank cover is integrally provided with a filter cartridge, and the filter cartridge The bottom of the filter cartridge is detachably provided with a leaking bottom cartridge, the surface of which is provided with a plurality of leaking holes, a plurality of aluminum alginate adsorption filter elements are stacked inside the filter cartridge, a wastewater inlet connected to the filter cartridge is provided on the top of the tank cover, and a clean water outlet is provided at the bottom of the heating tank. When in use, the utility model cooperates with the aluminum alginate adsorption filter element in the filter cartridge through the heating tank, so that the aluminum alginate adsorption filter element can quickly adsorb fluoride in the wastewater, and the leaking bottom cartridge detachably provided at the bottom of the filter cartridge can facilitate quick replacement of the aluminum alginate adsorption filter element. Compared with traditional fluoride-containing wastewater defluorination equipment, it can improve work efficiency and reduce the work difficulty of operators.

[0003] However, in actual application, the above device still has the following problems: first, only the hot aluminum alginate adsorption filter element that is in direct contact with the heating coil can better react with the fluorine-containing wastewater, and the position near the middle of the aluminum alginate adsorption filter element is far away from the heating coil, which is prone to insufficient reaction temperature, resulting in unsatisfactory defluorination effect of the fluorine-containing wastewater flowing through the middle of the aluminum alginate adsorption filter element, affecting the overall defluorination effect of the device; secondly, when the aluminum alginate adsorption filter element needs to be replaced, the tank cover connected by the bolts must be removed from the upper flange seat. The process of loading and unloading the bolts and removing the aluminum alginate adsorption filter element is relatively time-consuming, and it is still not convenient to use. Utility Model Content
