Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and more specifically, to a turntable wheel adsorption and concentration device for waste gas treatment. Background Art

[0002] Zeolite rotor plays an important role in waste gas treatment. During the waste gas treatment process, the zeolite rotor can adsorb harmful substances in the waste gas, such as VOCs, sulfides, nitrides, etc. Through adsorption, the zeolite rotor can significantly reduce the concentration of waste gas, so that it meets environmental protection standards and reduces pollution to the environment. After the zeolite rotor adsorbs harmful substances in the waste gas, these harmful substances need to be desorbed from the zeolite rotor in a certain way. The desorbed harmful substances can be further processed, such as incineration, catalytic combustion, etc., to achieve resource recovery and reuse.

[0003] The adsorption area and desorption area of ​​the existing zeolite wheel adsorption device are fixed and cannot be adjusted. However, with the use of the zeolite wheel, its adsorption capacity will gradually deteriorate. This is mainly because certain components in the exhaust gas react chemically with the zeolite, causing the zeolite surface to be covered or blocked, thereby reducing its adsorption performance. In the later stage of use, the adsorption effect of the wheel will deteriorate, and thus the effect of exhaust gas treatment will also deteriorate. This may increase the emission concentration of exhaust gas and have adverse effects on the environment. In addition, the effect of exhaust gas treatment cannot be detected in time. Even if the adsorption capacity of the zeolite wheel has dropped significantly, or the exhaust gas treatment effect has deteriorated, the operator cannot be informed in time, and thus cannot take corresponding measures in time. Summary of the invention

[0004] The present invention aims to overcome the defects of the prior art and provides a turntable wheel adsorption concentration device for waste gas treatment.

[0014] Further, the first air guiding hole faces the second air guiding hole.

[0015] Furthermore, the detachment and expansion part also includes a detection unit, which includes a first hinge seat installed at the bottom of the box body, an electric telescopic rod hinged to the first hinge seat, a second hinge seat hinged to the other end of the electric telescopic rod, a rotating plate fixedly connected to the second hinge seat, a second connecting block connected to the rotating plate, a second annular portion connected to the second connecting block, a second bearing connecting the second annular portion and the rotating shaft, a cylindrical portion with open ends connected to the rotating plate through a third connecting block, and a gas detection device, wherein the gas detection device includes a detection device body and a detection tube connected to the detection device body through a connecting hose, and the detection tube is inserted into the cylindrical portion; the rotating plate can abut against the first connecting flat plate.

[0034] Furthermore, the desorption air inlet pipe is connected to the end plate of the corresponding desorption cover, and the desorption air outlet pipe is connected to the end plate of the corresponding desorption cover. The desorption air inlet pipe, the desorption air outlet pipe and the cooling air outlet pipe are all connected with flanges.

[0035] The flange thus facilitates the connection of the pipes.

[0060] Working principle: As shown in the figure, the rotor of the rotary adsorption device of the present application is always in a rotating state, and the exhaust gas enters from the rectangular air inlet hole of the front plate (most of which passes through the adsorption area, and a small part passes through the cooling area to cool the zeolite after desorption). After passing through the adsorption area of ​​the zeolite turntable, the pollutants therein are adsorbed and concentrated. The zeolite turntable continues to rotate, and adsorbs the exhaust gas in the adsorption area. When it rotates to the desorption area, the high-temperature gas enters from the desorption air inlet pipe and exits from the desorption air outlet pipe, thereby realizing the desorption of the zeolite turntable. The wind coming out of the desorption air outlet pipe is burned and processed by subsequent combustion equipment (such as RTO equipment).

[0061] And when the wheel is in use, the rotating plate can be driven to rotate by lifting the electric telescopic rod, so that the sampling and detection of the gas at different positions of the zeolite turntable can be realized (the two gas detection devices detect the gas before and after adsorption respectively, so that the effect of the adsorption treatment can be more intuitively known). Since the adsorption effect of the zeolite turntable gradually worsens when it is closer to the desorption area, sampling and detection at different positions before the desorption area can better monitor the overall adsorption effect of the zeolite turntable.

[0062] If no expansion is required, Figure 2 As shown, the movable cover unit does not actually play a role (at this time, the movable plate will rotate in the direction of the first connecting plate due to the limitation of the circular protrusion, and will not block the desorption air inlet pipe and the desorption air outlet pipe), and the desorbed wind enters from the desorption air inlet pipe and exits from the desorption air outlet pipe. When expansion is required, the driving cylinder is shortened, so that the arc surface pressing plate does not press against the movable cover unit. At this time, by shortening the electric telescopic rod, the rotating plate rotates downward. The movable cover unit will press against the rotating plate under the action of its own weight and rotate downward with the rotating plate. After reaching the set position, the driving cylinder is extended, so that the arc surface pressing plate presses against the movable cover unit, so that the desorption area is actually larger at this time, so that the zeolite turntable can be better desorbed when the speed of the zeolite turntable remains unchanged. At this time, in addition to the desorption air inlet pipe for air intake and the desorption air outlet pipe for air outlet, one of the two air guide pipes is used for hot air intake and the other is used for hot air outlet, thereby increasing the desorption airflow and achieving a better desorption effect.

[0063] Regardless of whether the desorption expansion part is in a non-expanded state or an expanded state, since the movable cover unit is pressed against the arc-shaped pressing plate driven by the driving cylinder, the electric telescopic rod can independently drive the rotating plate to rotate, thereby realizing sampling and detection of different positions of the adsorption area, thereby having a more comprehensive monitoring of the adsorption effect at different positions of the adsorption area.

[0064] Although the present invention has been illustrated and described with respect to the preferred embodiments, it will be appreciated by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
