Embodiment 2
[0029] The catalyst packing described in this embodiment is prepared by using coconut shell carbon with a diameter of 2-4mm as the base material, soaking in 3% copper sulfate solution for 28 hours, and then sintering and solidifying copper at 330°C.
[0030] A catalytic oxidation defoaming device (such as figure 1 shown), including a tank body, water inlet pipe, air inlet pipe, catalyst packing area, and water outlet pipe. The water inlet pipe is arranged at the bottom of the tank body, and the water outlet pipe is arranged at the top of the tank body. Between the water inlet pipe and the water outlet pipe, the inlet pipe is arranged between the catalyst packing area and the water inlet pipe, and the above catalyst packing is filled in the catalyst packing area. The thickness of the catalyst packing area is 1.5m.
[0031] The results of the application experiments are the same as those in the examples and are omitted.
Embodiment 3
[0033] The catalyst packing described in this embodiment is prepared by using coconut shell carbon with a diameter of 2-4mm as the base material, soaking in 8% copper sulfate solution for 20 hours, and then sintering and solidifying copper at 270°C.
[0034] A catalytic oxidation defoaming device (such as figure 1 shown), including a tank body, water inlet pipe, air inlet pipe, catalyst packing area, and water outlet pipe. The water inlet pipe is arranged at the bottom of the tank body, and the water outlet pipe is arranged at the top of the tank body. Between the water inlet pipe and the water outlet pipe, the inlet pipe is arranged between the catalyst packing area and the water inlet pipe, and the above catalyst packing is filled in the catalyst packing area. The thickness of the catalyst packing area is 1.0m.
[0035] Application experiment result is identical with embodiment 1, omits.
