Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment devices, and in particular to an adsorption catalytic device for industrial organic waste gas. Background Art

[0002] With the acceleration of industrialization, organic waste gas emitted from various industrial production activities has become a serious environmental problem. These waste gases contain a variety of harmful substances such as benzene, toluene, xylene, formaldehyde, etc., which pose a huge threat to human health and the ecological environment. Traditional waste gas treatment methods such as direct combustion and condensation have limitations such as low efficiency, high cost or narrow scope of application. Against this background, adsorption catalytic devices for industrial organic waste gas came into being. Adsorption catalytic technology combines the high efficiency of adsorption and the thoroughness of catalysis. It uses the strong adsorption capacity of the adsorbent to first concentrate the organic matter in the waste gas, and then use the catalyst to promote the oxidation reaction of the organic matter at a lower temperature to convert it into harmless substances. The activated carbon adsorption concentration - RCO catalytic oxidation device uses activated carbon to adsorb organic waste gas. When the activated carbon reaches adsorption saturation, hot air is used to desorb the activated carbon to desorb the adsorbed organic waste gas. The high-concentration organic waste gas after desorption enters the RCO catalytic oxidation furnace. Under the action of the catalyst, the organic waste gas undergoes oxygen-free combustion at a lower ignition temperature and is converted into harmless substances such as carbon dioxide and water. During the desorption process, the scouring of hot air and the change in temperature increase the friction between the activated carbon particles, causing the activated carbon to break and pulverize, reducing the height of the activated carbon in the adsorption bed. If the exhaust gas contains corrosive components, it will corrode the activated carbon, causing the activated carbon on the activated carbon adsorption bed to be lost. The loss of activated carbon will reduce the effective adsorption area of ​​the adsorption bed, affecting the adsorption effect, and thus causing limitations.

[0003] To this end, we propose an adsorption catalytic device for industrial organic waste gas. Summary of the invention

[0021] In the present invention, the adding mechanism includes a storage box 5, an adding pipe 51 and a blocking block 52; the storage box 5 is fixedly connected to the outer shell 21; a through groove 53 is provided on the outer shell 21; the adding pipe 51 is fixedly connected to the storage box 5 and is connected to the through groove 53; a moving groove 54 is provided below the storage box 5; a moving motor 55 is fixedly connected in the moving groove 54, and the blocking block 52 is slidably connected in the moving groove 54; a screw rod which is threadedly matched with the blocking block 52 is fixedly connected to the output end of the moving motor 55; and an electromagnetic valve is provided on the adding pipe 51.

[0023] In the present invention, the industrial organic waste gas enters the shell 21 from the pipe on the shell 21 of the adsorption mechanism 2, moves from the inside of the shell 21 to the other side, enters the adsorption bed 22 from the vent hole 57, and is adsorbed by the activated carbon in the adsorption bed 22 after entering the adsorption bed 22. A partition plate 23 is provided in the adsorption bed 22, and holes are provided on the partition plate 23, so that the activated carbon can be separated and the industrial organic waste gas does not affect the passage of the adsorption bed 22; when the activated carbon is saturated with adsorption, the sealing electric push rods 58 on the front and rear sides of the adsorption bed 22 push the sealing plate 56, so that the sealing plate 56 seals the two sides of the adsorption bed 22, and then the hot air circulation mechanism 4 blows hot air into the adsorption bed 22 for circulation, so that the organic waste gas adsorbed by the activated carbon is separated from the activated carbon, and then the hot air carrying the industrial organic waste gas is introduced into the catalytic mechanism 3, so that the catalytic mechanism 3 catalytically reduces the industrial organic waste gas; In the present invention, when the blocking block 52 is in the initial position, it is located below the adding pipe 51 and blocks the adding pipe 51. When the activated carbon in the adsorption bed 22 is consumed, the amount of activated carbon in the adsorption bed 22 is reduced, so that the moving motor 55 drives the corresponding screw rod to rotate, so that the blocking block 52 moves to the left, exposing the lower end of the adding pipe 51, so that the solenoid valve on the adding pipe 51 is opened, and the activated carbon in the storage box 5 falls onto the adsorption bed 22 through the adding pipe 51; the adding pipe 51 is closed after adding a part of the activated carbon, and the blocking block 52 pushes the activated carbon, so that the added activated carbon is evenly distributed on the adsorption bed 22, and then the solenoid valve is opened again to add the activated carbon again; The present invention arranges a storage box 5, an addition pipe 51 and a blocking block 52 above the adsorption bed 22, and adds activated carbon in the adsorption bed 22 after the activated carbon in the adsorption bed 22 is consumed, thereby preventing the activated carbon from being consumed or pulverized, resulting in a reduction in the volume of the activated carbon in the adsorption bed 22, thereby weakening the adsorption effect on organic waste gas.

[0025] In the present invention, two groups of adsorption mechanisms 2 are provided, and the two groups of adsorption mechanisms 2 absorb organic waste gas at intervals. Therefore, when one group of adsorption mechanisms 2 heats the activated carbon and discharges the organic waste gas into the catalytic mechanism 3, the other group of adsorption mechanisms 2 is still working, thereby making the absorption of organic waste gas uninterrupted and improving the treatment efficiency.

[0026] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 5 , 6 and 7. In the present invention, a connecting groove 6 is provided at the lower end of the adsorption bed 22; a telescopic groove 61 is provided on the side wall of the connecting groove 6; a telescopic plate 62 is slidably connected in the telescopic groove 61, and a telescopic electric push rod 63 is fixedly connected in the telescopic groove 61; the output end of the telescopic electric push rod 63 is fixedly connected to the telescopic plate 62.

[0027] In the present invention, a stirring motor 7 is fixedly connected in the bottom box 24 ; and a conveying dragon 71 is fixedly connected to the output end of the stirring motor 7 .

[0028] In the present invention, one end of the bottom box 24 away from the conveying dragon 71 is fixedly connected to a pushing motor 72 and is slidably connected to a pushing plate 73; the output end of the pushing motor 72 is fixedly connected to a screw rod threadedly matched with the pushing plate 73; a vibration component 8 is fixedly connected to the adsorption bed 22; the vibration component 8 is composed of a motor and a deflection block; a hole is opened at the bottom of the adsorption bed 22.

[0029] In the present invention, a discharge groove 74 is provided on the side wall of the housing 21 ; the position of the discharge groove 74 corresponds to the conveying dragon 71 ; a discharge block 75 is provided in the discharge groove 74 ; and the discharge block 75 is fixed to the housing 21 by bolts.

[0030] In the present invention, the waste gas contains high boiling point, macromolecular organic matter or particulate matter, which will block the pores of the activated carbon and affect the adsorption effect. Therefore, it is necessary to replace the activated carbon in the adsorption bed 22 that first contacts the organic waste gas; In the present invention, the telescopic electric push rod 63 in the telescopic groove 61 pulls the telescopic plate 62 back, so that the telescopic plate 62 is retracted into the telescopic groove 61, so that the activated carbon of this part falls into the bottom box 24 below, and the staff unscrews the bolts on the discharge block 75 and takes out the discharge block 75, and then the stirring motor 7 drives the conveying dragon 71 to rotate, so that the conveying dragon 71 discharges the activated carbon out of the discharge groove 74. After the activated carbon is discharged, the discharge block 75 is inserted into the discharge groove 74 and fixed with bolts. At the same time, the telescopic electric push rod 63 pushes the telescopic plate 62 out of the telescopic groove 61, so that the telescopic plate 62 blocks the connecting groove 6, and then the adding pipe 51 adds new activated carbon to the part of the activated carbon in the adsorption bed 22 that is emptied, thereby completing the replacement of the activated carbon in the adsorption bed 22 that first contacts the organic waste gas; In the present invention, the vibration component 8 generates vibration, causing the adsorption bed 22 to vibrate, so that the powder generated by the pulverization of the activated carbon moves downward in the adsorption bed 22, and then falls to the bottom of the adsorption bed 22 and passes through the holes at the bottom of the adsorption bed 22, and falls into the bottom box 24, while large particles of activated carbon cannot pass through the holes at the bottom of the adsorption bed 22. Therefore, the present invention can discharge the activated carbon powder in the adsorption bed 22, and at the same time, the push motor 72 drives the corresponding screw to rotate, so that the push plate 73 pushes the activated carbon powder in the bottom box 24, so that the activated carbon powder gathers toward the conveying dragon 71, and then is discharged through the conveying dragon 71; The present invention moves the telescopic plate 62 so that the activated carbon in the adsorption bed 22 that first contacts the organic waste gas falls into the bottom box 24 and is then discharged through the conveying dragon 71. The telescopic plate 62 re-blocks the connecting groove 6, and then the activated carbon is added through the adding pipe 51, thereby completing the replacement of the activated carbon in the adsorption bed 22 that first contacts the organic waste gas, thereby preventing the pores of the activated carbon that first contacts the organic waste gas from being blocked by macromolecular organic matter, thereby affecting the adsorption effect.
