Problems solved by technology

[0006] However, for the purification of waste gas from papermaking, conventional physical and chemical treatment methods on the market have complex operations, high processing costs, and secondary pollution problems; and the existing commonly used papermaking waste gas purification equipment also has the following shortcomings:
[0009] Third: some papermaking waste gas purification equipment will use disinfectant spray inside, but the disinfectant spray assembly in the existing papermaking waste gas purification equipment is fixed, which will reduce the contact surface with the waste gas, which also will lead to poor spray effect

Embodiment 1

[0044]The operation process of Embodiment 1 is as follows: first, the infusion pump 29 extracts the spray liquid in the waste gas purification spray storage tank 2 and lifts it to the connection spray rack 12, and sprays it in real time by the spray head 13; at the same time, start The motor 9 fixed on the outside of the device housing 1 performs forward and reverse work alternately. The motor 9 drives the helical rotating rod 10 to rotate through the rotating end, thereby driving the moving sleeve 11 to move back and forth on the helical rotating rod 10, thereby realizing the spray rack 12 and a plurality of shower heads 13 that drive the lower end to move at a constant speed inside the device housing 1 .

[0045] The exhaust gas is transported into the device housing 1 successively from the exhaust gas inlet pipe 3, and at the same time, the electric heating wire 8 set in the exhaust gas inlet pipe 3 burns and heats the exhaust gas, so that the heat-sensitive substances in th...

Embodiment 2

[0048] Such as Figure 4 Shown, embodiment 2: a kind of papermaking exhaust gas purification device, with figure 1 Compared with the illustrated embodiment 1, the difference is that the embodiment 2 is also provided with a return air pipeline 25 on the upper end of the device housing 1 and below the air outlet 4, and the return air pipeline 25 is provided with a return air blower 26. The outlet 27 of the air pipeline 25 corresponds to the bottom of the fourth activated carbon filter adsorption unit 18 .

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

[0050] The operation process of embodiment 2 is as follows: first, the spray liquid in the exhaust gas purification spray storage tank 2 is extracted and lifted to the connection spray rack 12 by the infusion pump 29, and sprayed in real time by the spray head 13; at the same time, start The motor 9 fixed on the outside of the device housing 1 performs forward and reverse work alt...

Embodiment 3

[0054] Such as Figure 5 Shown, embodiment 3: a kind of papermaking exhaust gas purification device, with Figure 4 Compared with the shown embodiment 2, the difference lies in that the return air pipeline 25 also has a second outlet 28 , and the second outlet 28 corresponds horizontally between the first activated carbon filter adsorption unit 15 and the second activated carbon filter adsorption unit 16 .

[0055] The first stage of the operation process of embodiment 3 is the same as that of embodiment 2; when the gas is adsorbed by the fourth activated carbon filter adsorption unit 18, part of the gas will be pumped through the outlet 27 under the action of the return air fan 26 Returning to the bottom of the fourth activated carbon filter adsorption unit 18, part of the gas will be horizontally drawn back to the cavity between the first activated carbon filter adsorption unit 15 and the second activated carbon filter adsorption unit 16 through the second outlet 28 to form ...

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...
