Example Embodiment

[0044] The operation process of Embodiment 1 is as follows: First, the infusion pump 29 extracts and lifts the spray liquid in the exhaust gas purification spray tank 2 to the connecting spray frame 12, and the spray head 13 performs real-time spraying; at the same time, start The motor 9 fixed on the outside of the device housing 1 performs alternating forward and reverse rotation. The motor 9 drives the spiral rotating rod 10 to rotate through the rotating end, thereby driving the moving sleeve 11 to move back and forth on the spiral rotating rod 10, thereby realizing the spray frame 12 and the plurality of shower heads 13 at the lower end are driven to move at a uniform speed inside the device housing 1.

[0045] Exhaust gas is successively transported from the exhaust gas inlet pipe 3 into the device casing 1, and at the same time, the heating wire 8 arranged in the exhaust gas inlet pipe 3 burns and heats the exhaust gas, so that the heat-sensitive substances in the exhaust g...

Example Embodiment

[0048] Such as Figure 4 As shown, Example 2: A papermaking waste gas purification device, and figure 1 Compared with the shown embodiment 1, the difference is that; embodiment 2 is also provided with a return air pipeline 25 at the upper end of the device housing 1 and below the air outlet 4, and a return air fan 26 is provided on the return air pipeline 25. The outlet 27 of the air pipe 25 corresponds to the bottom of the fourth activated carbon filtration and adsorption unit 18.

[0049] Among them, it is better that the outlet 27 is inclined downward during implementation.

[0050] The operation process of Embodiment 2 is as follows: First, the infusion pump 29 extracts and lifts the spray liquid in the exhaust gas purification spray tank 2 to the connecting spray frame 12, and the spray head 13 performs real-time spraying; at the same time, start The motor 9 fixed on the outside of the device housing 1 performs alternating forward and reverse rotation. The motor 9 drives the ...

Example Embodiment

[0054] Such as Figure 5 As shown, Example 3: A papermaking waste gas purification device, and Figure 4 Compared with the second embodiment shown, the difference lies in that: the air return pipe 25 also has a second outlet 28, and the second outlet 28 level corresponds to between the first activated carbon filtration adsorption unit 15 and the second activated carbon filtration adsorption unit 16.

[0055] The first part of the operation process of Example 3 is the same as that of Example 2; after the gas is adsorbed by the fourth activated carbon filter and adsorption unit 18, part of the gas will be under the action of the return air blower 26, and part of the gas will be pumped here through the outlet 27 Back under the fourth activated carbon filtration and adsorption unit 18, part of the gas will be horizontally drawn back to the cavity between the first activated carbon filtration and adsorption unit 15 and the second activated carbon filtration and adsorption unit 16 throu...

Abstract

The invention discloses a device for purifying paper-making waste gas and an operation method of the device. Through the improved device for purifying the paper-making waste gas, the dispersed waste gas can be in full contact with treatment fluid, so that the purifying efficiency is improve; on the other hand, multi-stage filtration adsorption is adopted so that purification and filtration of thewaste gas can be achieved well; on the whole, the device for purifying the paper-making waste gas has the advantages of a simple structure, convenient use and maintenance, thorough purification and convenient treatment of the waste gas; meanwhile, another purpose of the arrangement of the multi-stage filtration adsorption unit is that the ascending speed of the gas can be slowed down through the multi-layer adsorption, so that the gas stays inside the housing of the device slightly, and spraying and adsorption are achieved fully.

Description

technical field [0001] The invention relates to the field of papermaking waste gas purification, in particular to a papermaking waste gas purification device and an operation method. Background technique [0002] At present, no matter in terms of life or work and study, paper is almost inseparable. However, a large amount of waste gas will be generated in the papermaking process. If it is discharged into the atmosphere, it will inevitably pollute the surrounding environment and cause harm to human health; therefore, it is very important to purify papermaking waste gas; there are also many equipment for papermaking waste gas purification. [0003] After searching, it was found that the patent No. CN201620351184.0 discloses a papermaking waste gas purification and removal device, which includes a housing, an air outlet is provided on the top of the housing, and a mounting plate is provided above the liquid chamber, and the mounting plate is evenly opened. Ventilation hole, th...
