Description

Technical Field

[0001] The utility model relates to the technical field of Fenton treatment, in particular to a Fenton treatment device. Background Art

[0002] Fenton treatment is a common water treatment technology used to treat wastewater containing organic matter. It decomposes organic matter by oxidation and converts it into carbon dioxide, water and harmless inorganic matter. When Fenton treatment is performed, a reactor is used to transport wastewater to the reactor for treatment. The existing wastewater Fenton treatment device (publication number: CN218232019U) includes a Fenton treatment tower, a water inlet pump, a quantitative dosing device, an ozone generator and a PLC controller; the upper and lower parts of the Fenton treatment tower are connected through a circulating water pipe with a circulating water pump to form a circulation loop; the water inlet pump is connected to the bottom of the Fenton treatment tower through the water inlet pipeline; the quantitative dosing device includes a reagent tank and a dosing pipeline with a dosing pump, and the reagent tank is connected to the water inlet pipeline through the dosing pipeline; the ozone generator is connected to the circulating pipeline between the circulating water pump and the Fenton treatment tower through a pipeline; the circulating water pump, the water inlet pump, the dosing pump and the ozone generator are connected to the PLC controller and controlled by the PLC controller. The utility model effectively improves the treatment effect by combining ozone oxidation with Fenton oxidation to form a circulation loop, and has a short treatment time and high treatment efficiency. However, at least the following defects are exposed during use:

[0003] 1. In a conventional Fenton treatment device, reagents need to be added in a quantitative manner to ensure the control of reaction conditions and effects. However, when adding reagents, the staff may directly put the reagents into the treatment device, and thus cannot accurately control the amount and proportion of the reagents added, resulting in uncertainty in the reaction conditions.

[0004] 2. Usually, harmful gases will be produced after the wastewater reacts in the reactor. However, when eliminating harmful gases, they are usually purified only through the activated carbon layer. As a result, different harmful gases may not be easily adsorbed by the activated carbon, resulting in unsatisfactory treatment effects and easily causing pollution to the air environment.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] like Figures 2 to 3 As shown, through the set quantitative box 8, electric push rod 9, connecting plate 10, baffle 11, connecting tube 12, weight sensor 14 and controller 23, the reagent is put into the quantitative box 8, and the weight sensor 14 is used to weigh the reagent put into the quantitative box 8, and the weight sensor 14 will transmit the signal to the controller 23. If the required amount of input is reached, the controller 23 will open the electric push rod 9, so that the electric push rod 9 drives the connecting plate 10 and the baffle 11 to move upward, and then the baffle 11 will drive the sealing gasket 15 to separate from the inclined plate, and the connecting The tube 12 is opened, so that the quantitative reagent is transported to the reaction box 1 through the connecting tube 12. The sealing gasket 15 and the inclined plate are provided, and the sealing gasket 15 can prevent the reagent from flowing away, and the inclined plate can play an auxiliary role in the reagent, which is convenient for the reagent to flow. Therefore, through the cooperation of the weight sensor 14, the controller 23 and the electric push rod 9, it is convenient to quantitatively process the reagent, thereby improving the effect of wastewater treatment and the accuracy of the reaction conditions. After the reagent is put into the reaction box 1, the wastewater and the reagent can be mixed by the stirring rod 6, so that the wastewater reacts;

The catalyst layer 18 can promote the chemical reaction of the substance and convert the harmful substance into harmless substance. After passing through the catalyst layer 18, it will pass through the activated carbon layer 19.

Therefore, through the cooperation of the catalytic layer 18, the activated carbon layer 19, the absorption layer 20 and the screening membrane 21, the purification of harmful gases by only activated carbon is avoided, thereby effectively improving the treatment effect of harmful gases and preventing air pollution. The catalytic layer 18 can be made of platinum, platinum tin and other materials, and the screening membrane can be made of polyester materials. The absorption layer 20 can be made of materials such as molecular sieves. Molecular sieves are microporous crystals with controllable pore diameters and structures that can selectively adsorb specific molecules.

If the required amount of input is reached, the controller 23 will turn on the electric push rod 9, so that the electric push rod 9 drives the connecting plate 10 and the baffle 11 to move upward, so that the quantitative reagent is transported to the reaction box 1 through the connecting tube 12, so as to facilitate the quantitative treatment of the reagent, thereby improving the effect of wastewater treatment and the accuracy of the reaction conditions; by setting The exhaust fan 17, the catalyst layer 18, the activated carbon layer 19, the absorption layer 20 and the screening membrane 21, when reacting with the wastewater, the exhaust fan 17 is turned on, and the harmful gas will enter the purification box 16 through the through hole 24, and then pass through the catalyst layer 18, the catalyst layer 18 can promote the substance of the chemical reaction and convert the harmful substance into harmless substance, the activated carbon layer 19 can adsorb many harmful gases, and then the absorption layer 20 can react chemically with the harmful gas and absorb the substance, and finally the screening membrane 21 can selectively separate the gas according to the molecular size and characteristics, avoiding the purification of the harmful gas only by the activated carbon, thereby effectively improving the treatment effect of the harmful gas and preventing the pollution in the air.
