Description

Technical Field

[0001] This utility model belongs to the field of solid waste incineration exhaust gas treatment technology, specifically relating to a rotary kiln incineration exhaust gas treatment device. Background Technology

[0002] A rotary kiln is a device used for high-temperature calcination of solid materials. During the combustion process, it generates solid waste gas, often referred to as solid waste gas. This solid waste gas typically contains solid dust and acidic gases (such as HCl, SO2, and NO). x Pollutants such as heavy metals and dioxins are generally treated by different waste gas treatment equipment. Activated carbon adsorption boxes are waste gas treatment devices that adsorb solid particles and dust from solid waste gas. The main structure includes an adsorption box and internal activated carbon. It mainly uses the adsorption capacity of the porous structure of activated carbon to adsorb and retain pollutants such as solid particles and dust in the waste gas. An activated carbon adsorption box is disclosed in document CN222738803U. Using the adsorption capacity of activated carbon to treat waste gas is an existing technology.

[0003] Activated carbon adsorption boxes adsorb solid particles and dust in exhaust gas. Solid particles and dust will form a layer of ash on the surface of activated carbon. Under long-term use, the ash layer accumulated on the surface of activated carbon will cause blockage, affecting the flow of exhaust gas. In addition, it will also reduce the adsorption capacity of activated carbon. Generally, manual replacement of activated carbon is required, which is a relatively complicated process. The activated carbon adsorption box does not have a design to self-clean the ash layer on the surface of activated carbon, which is a shortcoming.

[0004] Existing activated carbon adsorption boxes lack a self-cleaning activated carbon surface ash layer when adsorbing solid particles and dust in incineration waste gas. To address this, this application proposes a rotary kiln incineration waste gas treatment device. Utility Model Content

Figure 1 The exhaust gas enters from direction a through the exhaust gas inlet pipe 11 into the interior of the activated carbon adsorption box 1. The exhaust gas is adsorbed by the honeycomb-shaped first activated carbon module plates 7 arranged side-by-side. The exhaust gas, which adsorbs solid particles and dust, is discharged along direction b for further processing by the next equipment. The lifting mechanism includes an electric push rod 21 fixed to the activated carbon adsorption box 1 by screws, a connecting arm 22 fixed to the top of the electric push rod 21 by screws, and a gas conveying assembly. The electric push rod 21 is a device whose structure and principle are disclosed in this application and will not be described in detail here. As described above, when the electric push rod 21 operates, it drives the connecting arm 22 and the air storage pipe 23 to rise and fall vertically. Subsequently, the air delivery pipe 51, the nozzle 54, and the cleaning plate 53 also rise and fall vertically. The cleaning plate 53 brushes away the accumulated dust layer adsorbed on the surface of the first activated carbon module plate 7, restoring the adsorption capacity of the first activated carbon module plate 7 and providing a self-cleaning function.

The inlet circular pipe 231 is combined with external gas delivery equipment, such as an air pump. External gas is delivered into the gas storage pipe 23 through the inlet circular pipe 231. Then, the gas inside the gas storage pipe 23 is divided and transported along the path of the gas delivery pipe 51, the diverter plate 52, and the jet nozzle 54. The gas ejected from the jet nozzle 54 blows away the dust layer brushed off by the cleaning plate 53. The transported dust falls to the bottom of the activated carbon adsorption box 1.

The gas supply pipe 51 can move vertically up and down with the gas storage pipe 23. A square groove is opened on the top surface of the activated carbon adsorption box 1. The gas storage pipe 23 has a square cross-section. The gas storage pipe 23 cooperates with the square groove and is engaged with the activated carbon adsorption box 1. The gas storage pipe 23 seals the gap between the gas supply pipe 51 and the surface of the activated carbon adsorption box 1 to prevent waste gas leakage.

[0031] In this embodiment, the fixed frame 6 is pulled out and connected to the activated carbon adsorption box 1. The inner surface of the bottom end of the fixed frame 6 is a slope c. The dust brushed off the surface of the first activated carbon module plate 7 falls on the slope c. The slope c has a slope, which is conducive to the gas blowing off the dust on the slope c and causing it to fall into the inside of the drawer box 4.

Then, the gas inside the gas storage pipe 23 is diverted and delivered along the path of gas delivery pipe 51, diverter plate 52, and jet nozzle 54. The gas sprayed from the jet nozzle 54 blows away the dust brushed off by the cleaning plate 53.

[0035] In this embodiment, a drawer box 4 is slidably connected to the bottom side of the activated carbon adsorption box 1. A support mesh 41 is fixed inside the drawer box 4 by screws. A split second activated carbon module plate 42 is provided on the surface of the support mesh 41 in the drawer box 4.

[0036] Working principle and usage process of this utility model:

[0037] When treating the exhaust gas generated by rotary kiln combustion, the exhaust gas flows along... Figure 1 The exhaust gas enters from the exhaust gas inlet pipe 11 into the interior of the activated carbon adsorption box 1 in the direction a. The exhaust gas is adsorbed by the honeycomb-shaped first activated carbon module plate 7 arranged side by side. The exhaust gas adsorbed with solid particles and dust is discharged in the direction b and is processed by the next equipment.

[0038] When the exhaust gas stops being transported and the first activated carbon module plate 7 is being cleaned, the electric push rod 21 is activated, and the electric push rod 21 drives the connecting arm 22 and the gas storage pipe 23 to rise and fall vertically.

[0039] The air supply pipe 51, the jet nozzle 54, and the cleaning plate 53 move vertically up and down accordingly. The cleaning plate 53 brushes away the dust layer adsorbed on the surface of the first activated carbon module plate 7, restoring the adsorption capacity of the first activated carbon module plate 7 and having a self-cleaning function.

[0040] Meanwhile, the intake pipe 231 is combined with external gas delivery equipment, such as an air pump, and external gas is delivered from the intake pipe 231 into the gas storage pipe 23. Then, the gas inside the gas storage pipe 23 is split and delivered along the path of the gas delivery pipe 51, the split plate 52, and the jet nozzle 54.

[0041] The gas ejected from the nozzle 54 blows away the dust layer brushed off by the cleaning plate 53, and the dust falls to the bottom of the activated carbon adsorption box 1.

[0042] The dust brushed off by the cleaning board 53 falls onto the surface of the second activated carbon module plate 42 inside the drawer box 4. The drawer box 4 is connected to the activated carbon adsorption box 1 by a pull-out mechanism. The drawer box 4 can be pulled outwards, making it easy to manually clean the dust that falls onto the surface of the second activated carbon module plate 42 and to manually replace the second activated carbon module plate 42.

[0043] In summary: The activated carbon adsorption box has a design that allows for the self-cleaning of the activated carbon surface dust layer. The electric push rod 21 drives the connecting arm 22, the gas storage pipe 23, the gas delivery pipe 51, the jet nozzle 54, and the cleaning plate 53 to move vertically up and down. The cleaning plate 53 brushes away the dust layer adsorbed on the surface of the first activated carbon module plate 7, restoring the adsorption capacity of the first activated carbon module plate 7, thus having a self-cleaning function.
