[0002] Coke oven waste gas treatment refers to a series of technical measures to purify the waste gas generated during the coking process. During the coking process, coal is pyrolyzed under high temperature and oxygen-deficient conditions to produce coke while also releasing waste gas containing a variety of pollutants. If these waste gases are directly discharged without treatment, they will cause serious pollution to the environment. The main purpose of coke oven waste gas treatment is to reduce pollutant emissions, protect the environment, and recover valuable resources at the same time.

[0003] During the treatment process, the exhaust gas contains not only exhaust gas components such as sulfides, but also a large amount of particulate impurities. If the solid waste is pretreated at this time, it is easy to cause incomplete treatment of sulfides. However, when using dust nets for dust removal and filtration, the dust nets need to be cleaned regularly to avoid clogging, and the disinfectant absorbent also needs to be replenished regularly, resulting in relatively high labor maintenance costs.

A drain pipe 18 is fixed to the bottom side wall of the waste liquid chamber 15, and a baffle 4 is fixed on the partition 11 and located between the dust removal chamber 12 and the disinfection chamber 13.

[0018] The vibration assembly includes a driving motor 24 and a connecting plate 22. The connecting plate 22 passes through the upper end of the dustproof net frame 2 and is fixedly connected to the dustproof net frame 2. A telescopic rod 23 is fixed at the middle position of the upper end of the connecting plate 22. The upper end of the telescopic rod 23 extends out of the purification box 1 and is fixedly slidably connected to the purification box 1. The driving motor 24 is fixed to the upper end of the purification box 1 and the output end of the driving motor 24 is aligned with the telescopic rod 23.

[0019] Working principle: First, the air intake pipe 16 is connected to the exhaust pipe of the coke oven. The exhaust gas enters the purification box 1 through the air intake pipe 16, passes through the dust removal chamber 12 and the disinfection chamber 13, and is discharged from the exhaust pipe 17. In this process, the dustproof net frame 2 can be used to block the solid waste in the exhaust gas. Then, the exhaust gas enters the disinfection chamber 13, and the booster pump 32 is used to increase the air pressure in the liquid storage tank 3, so that the absorbent can be sprayed out from the atomizing nozzle 31, and the sulfide in the gas is chemically reacted and solidified. After being filtered by the filter screen 5, the liquid enters the waste liquid chamber 1. 5 is collected, and the gas is discharged from the purification box 1. As the absorbent is continuously consumed, the page in the liquid storage tank 3 drops, and the liquid level sensor 33 is used to control the electromagnetic valve 35, so that the liquid inlet pipe 34 is replenished with absorbent. At the same time, when dust removal is performed, the rotation of the driving motor 24 can drive the special-shaped wheel 25 to rotate. At the same time, under the elastic reset of the reset spring 27, the dustproof net frame 2 is driven to vibrate continuously, and the accumulated solid waste is shaken off and falls from the perforation 26 into the collection chamber 14 for collection. The whole process reduces manual maintenance and reduces the manpower maintenance cost.
