Description

Technical Field

[0001] The utility model relates to the technical field of oxidation towers, in particular to Fenton atomization processing equipment. Background Art

[0002] The high-efficiency oxidation tower is used to treat wastewater with high concentration or difficult-to-degrade COD. Its main principle is to use the free hydroxyl groups produced by Fenton's strong oxidizing agent to strongly oxidize and break down the difficult-to-degrade molecules in the wastewater, thereby reducing the COD concentration of the wastewater. The Fenton reaction is an inorganic chemical reaction that has a high ability to remove difficult-to-degrade organic pollutants. It is widely used in the treatment of printing and dyeing wastewater, oily wastewater, phenol-containing wastewater, coking wastewater, nitrobenzene-containing wastewater, diphenylamine wastewater and other wastewater.

[0003] Since it is difficult to prepare chemicals effectively with conventional equipment, most of the chemicals lose their oxidizability before reacting with sewage, which not only results in a large amount of chemicals used and low treatment efficiency, but also a large amount of sludge output. Therefore, Fenton atomization treatment equipment is proposed. Through the setting of structures such as the drug inlet valve, the return pipe, the liquid outlet pipe and the atomizing nozzle, it is easy to add and mix the chemicals, reduce the reaction time between the chemicals and sewage, and improve the treatment efficiency. Utility Model Content

[0007] By adopting the above technical scheme, sewage flows into the loop pipe through the water inlet pipe, and the oxidant flows into the water inlet pipe through the medicine inlet valve and mixes with the sewage. After mixing, the oxidant is sprayed into the tower body from the atomizing nozzle through the liquid outlet pipe, which is convenient for adding and mixing the agent and can reduce the reaction time between the agent and sewage. The supporting filter plate is used to carry the flocculants, and the filler is used to filter the sewage.

[0008] Specifically, one outer end of the tower body located on the top of the supporting filter plate is connected to a flushing valve through a pipeline, and one outer end of the tower body away from the flushing valve is connected to a draining valve through a pipeline.

[0023] One end of the water inlet pipe 201 located inside the tower body 1 is connected to a loop pipe 202 through a pipe joint, the top of the loop pipe 202 is equidistantly connected to a liquid outlet pipe 206 through a threaded groove, the top of the liquid outlet pipe 206 is connected to an atomizing nozzle 208 through a threaded groove, and the end of the loop pipe 202 away from the water inlet pipe 201 is connected to a return pipe 203 through a pipe.

[0024] When in use, sewage flows into the return pipe 202 through the water inlet pipe 201, and the oxidant flows into the water inlet pipe 201 through the medicine inlet valve 204 to mix with the sewage. After mixing, the oxidant is sprayed into the tower body 1 from the atomizing nozzle 208 through the liquid outlet pipe 206, which is convenient for adding and mixing the agent and can reduce the reaction time between the agent and sewage. The supporting filter plate 4 is used to carry the flocculants, and the filler 7 is used to filter the sewage.

[0025] For example, Figure 2 As shown, the utility model also includes that the outer end of the tower body 1 located on the top of the supporting filter plate 4 is connected to a flushing valve 8 through a pipeline, and the outer end of the tower body 1 away from the flushing valve 8 is connected to an emptying valve 9 through a pipeline.

[0026] When in use, the flushing valve 8 is opened to allow external clean water to flow into the tower body 1 to flush the top of the supporting filter plate 4, and the flushed flocculants flow out through the emptying valve 9.

[0027] For example, Figure 3 As shown, the utility model also includes that one end of the tower body 1 is connected to a reflux valve 3 through a pipeline, the top of the reflux pipe 203 is connected to one end of the reflux valve 3 through a threaded groove, and a one-way valve 207 is sleeved on the outer end of the reflux pipe 203.

[0036] As the water level of the sewage and oxidant mixed water entering the tower body 1 gradually rises, the sewage and oxidant mixed water overflows the supporting filter plate 4, and the flocculants in the sewage and oxidant mixed water fall onto the supporting filter plate 4 due to their own weight. As the water level in the tower body 1 continues to rise, the sewage and oxidant mixed water contacts the filler 7 and is filtered by the filler 7.

[0037] The filtered sewage and oxidant mixed water is blocked by the first water distribution baffle 5 and the second water distribution baffle 6, a part of it flows out from the water outlet valve 10, and a part of it flows back from the return pipe 203 to the return pipe 202 through the return valve 3, and mixes with the oxidant again, reducing the outlet water pressure and improving the treatment and filtration efficiency;

[0038] Open the flushing valve 8 to allow external clean water to flow into the tower body 1 to flush the flocculants on the supporting filter plate 4, so that the flocculants can flow out through the emptying valve 9. The one-way valve 207 can prevent the liquid in the return pipe 202 from flowing back into the reflux pipe 203.
