[0032] Reference Figure 1 - Figure 3The catalytic component also includes a catalytic plate 26, which is an electrocatalytic oxidation electrode plate, which is divided into a cathode plate and an anode plate. The materials of the cathode plate and the anode plate are selected from one or more composites of titanium, carbon steel, stainless steel, and copper, and can be implemented by technicians in this field.

[0033] Reference Figure 1 - Figure 2 The purification component also includes a connecting pipe 33. Starting the pump body 34 sucks out the decomposition liquid at the bottom end of the inner wall of the tank body 1 through the connecting pipe 33, and discharges it to the upper side of the inner wall of the tank body 1 near the purification plate 31 through the water distribution pipe 32, so as to decompose the exhaust gas. The connecting pipe 33 passes through and is fixedly connected to the bottom end of the right surface of the tank body 1. The right surface of the connecting pipe 33 is fixedly connected to the pump body 34. The pump body 34 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The lower surface of the right end of the water distribution pipe 32 is fixedly connected to the upper surface of the left end of the pump body 34. The right surface of the tank body 1 near the lower side of the connecting pipe 33 passes through and is fixedly connected to a drain pipe 7. The drain pipe 7 can drain the spray water and can be replaced.

[0034] Reference Figure 2 - Figure 3 A dosing pipe 5 is fixedly connected to the lower side of the right surface of the bottom end of the tank body 1 near the sewage pipe 24, and the spray water on the inner wall of the tank body 1 is supplemented with a medicine through the dosing pipe 5. The medicine is one or more of sulfuric acid, hydrochloric acid, sodium hydroxide, sodium bicarbonate, hot water, and cold water. A detection tube 6 is fixedly connected to the lower side of the right surface of the bottom end of the tank body 1 near the dosing pipe 5.

A temperature measuring tube 4 is fixedly connected to the upper side of the left surface of the tank body 1 near the air inlet distribution pipe 23. The temperature measuring tube 4 can monitor the wastewater temperature.

If the wastewater temperature is too low, hot water can be added through the dosing tube 5 to increase the spray water temperature and heat the wastewater. The right surface of the temperature measuring tube 4 contacts the left surface of the cylindrical shell 25. The bottom end of the inner wall of the tank body 1 is fixedly connected with an oblique ring 8 near the outside of the cylindrical shell 25.

[0035] Working principle: Sewage enters the interior of the cylindrical shell 25 through the liquid inlet pipe 21 and undergoes a catalytic reaction under the action of the catalytic plate 26. Harmful tail gas is generated during the catalytic process. At this time, the fan 22 is started, and the outside air is inhaled into the cylindrical shell 25 through the air inlet distributing pipe 23. The air entering the interior of the cylindrical shell 25 will drive the tail gas inside the cylindrical shell 25 to enter the tank body 1 through the exhaust gas distributing pipe 27. The purification components inside the tank body 1 will filter the tail gas and then discharge it through the exhaust pipe 11.

[0036] During the purification process, the pump body 34 can be started to suck out the water containing decomposition agents at the bottom end of the inner wall of the tank body 1 through the connecting pipe 33 and discharge it through the water distributing pipe 32 to the upper side near the purification plate 31 on the inner wall of the tank body 1 to decompose the tail gas. The water circulates and sprays inside the tank body 1 to improve the decomposition effect. At the same time, the agent can be supplemented into the sprayed water on the inner wall of the tank body 1 through the chemical addition pipe 5, such as sulfuric acid, hydrochloric acid, sodium hydroxide, sodium bicarbonate, hot water, cold water, etc., to adjust the pH value and temperature of the sprayed water. The filter filler is added inside the purification plate 31 to filter the gas discharged into the tank body 1 and improve the absorption efficiency of the tail gas. The demister 35 can prevent the liquid phase from being entrained by the gas and entering the atmosphere.

[0037] In addition, the sewage after catalysis is discharged through the sewage discharge pipe 24, and the sprayed water can be drained and replaced through the drain pipe 7.

[0038] When the filler needs to be added to the purification plate 31, the limiting plate 9 can be rotated by holding the handle 10 so that the limiting plate 9 does not contact the purification plate 31. At this time, the purification plate 31 can be pulled out, and after the addition is completed, the purification plate 31 can be pushed back. Then, the purification plate 31 is limited by the limiting plate 9 to ensure the stability of the purification plate 31.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
