Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and in particular to a waste gas treatment device for bearing steel processing. Background Art

[0002] Bearing steel is steel used to make balls, rollers and bearing rings. Bearing steel has high and uniform hardness and wear resistance, as well as high elastic limit. The uniformity of the chemical composition of bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict. It is one of the most stringent steel grades in all steel production. Bearing steel will be subjected to high temperature operation during the processing process, which will produce a large amount of waste gas.

In the above application document, the exhaust gas can be sucked into the fixed box by an air pump, and the water in the fixed box can leave the insoluble matter in the exhaust gas in the fixed box, and then the second motor drives the multiple breaking leaves on the driving shaft to break up the bubbles to prevent the insoluble matter from being discharged, and then the exhaust gas enters the filter component and is filtered by the filter screen and the activated carbon filter screen and enters the bottom box, and then the treatment liquid is added into the bottom box, and the first motor drives the multiple stirring leaves on the rotating shaft to rotate, so that the exhaust gas and the treatment liquid are mixed and treated, and the exhaust gas is fully treated. When the exhaust gas enters the fixed box again, the insoluble matter may not be completely separated from the exhaust gas, which is not conducive to the subsequent exhaust gas treatment.

The water suction pipe absorbs the water in the spray water tank through the cooperation of the rotating gear, the gear rod, the pressure tank and other components and discharges it to the atomizing nozzle through the water outlet pipe. The water is atomized and sprayed in the treatment tank to spray the exhaust gas, thereby further removing the insoluble matter mixed in the exhaust gas and preventing incomplete removal.

[0016] 2. The present invention is provided with a rotating mechanism, so that when the motor is turned on to drive the stirring shaft to rotate and stir the water in the treatment tank, the atomizing nozzle is driven to rotate intermittently through the cooperation of components such as bevel gear A, bevel gear B, cross bar, and rotating rod.

[0023] In this embodiment, the air inlet pipe 3 is connected to the exhaust gas discharge point during the processing of bearing steel, and the fan 11 is turned on. At this time, the exhaust gas enters the processing tank 1 through the air inlet pipe 3 and the insoluble matter mixed in the exhaust gas is removed by the water in the processing tank 1. Then the exhaust gas enters the processing chamber 7 through the air outlet pipe 4. At this time, the dehumidification plate 8 will remove moisture from the exhaust gas, the filter plate 9 will preliminarily remove large particle pollutants in the exhaust gas, and the activated carbon plate 10 will absorb fine pollutants. Finally, the exhaust gas enters the exhaust pipe 12 and is irradiated and disinfected by the ultraviolet searchlight 13 before being discharged. When the exhaust gas enters the processing tank 1, the motor 5 can be turned on, and the motor 5 passes The output shaft drives the stirring shaft 6 to rotate. The stirring shaft 6 rotates to stir the water in the treatment tank 1 through the six groups of stirring blades on its surface, so that the exhaust gas and the water are in contact more fully. At the same time, the stirring shaft 6 also drives the rotating gear 141 to rotate. At the beginning, the upper teeth of the rotating gear 141 are engaged with the upper teeth of the gear rod 145, which drives the gear rod 145 to move left. The leftward movement of the gear rod 145 drives the piston rod 144 to move left, and the reset spring 143 is compressed. The leftward movement of the piston rod 144 will form a negative pressure in the pressure chamber 142, so that the water in the spray water chamber 147 is sucked through the water suction pipe 146.

[0025] In this embodiment, when the spray water is atomized by the atomizing nozzle 149 and then sprayed to treat the waste gas, when the water level in the treatment tank 1 continues to rise to the liquid level sensor 164, the liquid level sensor 164 will send a signal, and at this time, the drain pipe 161 will be opened through the solenoid valve 162 to drain water to prevent the water level from being too high. The filter screen 163 will prevent the discharge of debris, and the eccentric ring 169 will repeatedly squeeze the air bag 166 when rotating with the air pressure chamber 165, and the air bag 1 66 is squeezed and the air pressure inside it will enter the air pressure chamber 165 to push the push rod 167 to move left. The push rod 167 moves left and drives the exhaust brush 168 to move left. When the eccentric ring 169 leaves the airbag 166, the airbag 166 rebounds and the air pressure returns to the airbag 166. At this time, the push rod 167 drives the exhaust brush 168 to move right and restore.
