[0002] Baking soda solution is an aqueous solution with sodium bicarbonate, commonly known as baking soda, as its main component. It has wide applications in many industries, especially in chemical, food processing, and environmental treatment.

[0003] When filtering baking soda solution, a filter screen is usually used. Traditional filter screens are fixedly connected to the filter device, making them inconvenient to clean, which reduces the filtration effect. Impurities accumulated at the bottom of the filter device are also difficult to clean, reducing the purity of the baking soda solution. The baking soda solution cannot be evenly dispersed on the activated carbon, thus reducing the adsorption and filtration effect on dissolved organic matter and other trace pollutants.

The edges of filter screen 122 are fixed... A ring baffle 123 is installed to prevent sediment from falling. When the pump body 106 is turned on, the baking soda solution inside the diversion tank 102 is transported through the connecting pipe 112 to the Z-shaped pipe 105. A one-way valve 113 is installed on the outer surface of the connecting pipe 112 to prevent the baking soda solution from flowing back into the diversion tank 102. The Z-shaped pipe 105 transports the baking soda solution to the U-shaped pipe 119, and then diverts it into multiple conveying pipes 117, which are then sprayed onto the filter box 10 through multiple spray nozzles 118. The filter is evenly dispersed on the activated carbon inside the filter box 108 to improve its adsorption effect. This adsorbs dissolved organic matter and other trace pollutants in the baking soda solution, improving its purity. The filtered baking soda solution can be removed through the external pipe 111. The filter box 109 can be removed from the inside of the installation slot 108 for convenient periodic replacement of the activated carbon inside.
