Description

Technical Field

[0001] This utility model belongs to the field of activated carbon desorption technology, and in particular relates to an activated carbon adsorber for the treatment of waste gas by hot nitrogen desorption and regeneration. Background Technology

[0002] Hot nitrogen desorption is a technology that uses high-temperature nitrogen to regenerate activated carbon, mainly used in the adsorption-desorption cycle process in waste gas treatment. However, when activated carbon is placed on a carbon bed for desorption with hot nitrogen, the activated carbon at the bottom of the bed does not come into sufficient contact with the hot nitrogen due to its accumulation on the carbon bed, making it impossible for pollutant molecules in the pores of the activated carbon to detach from the activated carbon surface. In addition, when hot nitrogen desorbs activated carbon, it is impossible to determine the desorption status of pollutant molecules in the pores on the surface of the activated carbon.

[0003] To address these issues, we provide an activated carbon adsorber for hot nitrogen desorption and regeneration of waste gas, which solves the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide an activated carbon adsorber for hot nitrogen desorption and regeneration of waste gas. A pneumatic rotating assembly is installed inside the inlet chamber, and a turning paddle is installed inside the carbon bed. When hot nitrogen enters the carbon bed from the inlet chamber, it drives the pneumatic rotating assembly to rotate, which in turn drives the turning paddle to rotate, thus continuously agitating the activated carbon in the carbon bed and ensuring that all activated carbon particles are desorbed by the hot nitrogen. An anemometer is installed at the outlet of the desorption chamber, and the airflow velocity at the outlet is determined by the anemometer's rotation speed. When pollutant molecules in the activated carbon pores enter the gas phase, the restrictive effect of the activated carbon on the hot nitrogen decreases, thereby changing the airflow velocity at the outlet of the desorption chamber. The desorption status of the activated carbon is determined based on the airflow velocity.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an activated carbon adsorber for treating waste gas through hot nitrogen desorption and regeneration. It includes an inlet chamber and a desorption chamber. The outlet end of the inlet chamber is installed at the inlet end of the desorption chamber. A pneumatic rotating assembly is installed inside the inlet chamber. A carbon bed is sleeved inside the desorption chamber. A set of vent holes is opened at the lower end of the carbon bed. An agitator is rotatably installed inside the carbon bed. The agitator is connected to the pneumatic rotating assembly. An anemometer is installed inside the outlet pipe of the desorption chamber.

[0007] The present invention is further configured such that the pneumatic rotating assembly includes a pneumatic propeller bushing and a pneumatic propeller shaft. The pneumatic propeller bushing includes an outer ring and an inner shaft. The inner shaft is sleeved inside the outer ring and is fixedly connected to the outer ring via a connecting arm. The outer ring is fixedly installed on the inner wall of the air intake chamber. The middle section of the pneumatic propeller shaft is rotatably installed inside the inner shaft. A set of blades is axially arrayed and fixed on the outer side of the inner shaft at the end away from the carbon bed.

[0008] The present invention is further configured such that a tumbling paddle shaft hoop is fixedly provided at the upper end of the carbon bed, and the rotating shaft at the upper end of the tumbling paddle is rotatably sleeved in the tumbling paddle shaft hoop.

[0009] The present invention is further configured such that a transmission key is fixed on the outer side of the inner shaft hoop near the carbon bed, and a transmission groove is opened at the upper end of the agitator, with the transmission key sleeved in the transmission groove.

[0010] The present invention is further configured such that the outer side of the upper end of the carbon bed is threadedly connected to the inner side of the air outlet end of the air inlet chamber.

[0011] The present invention is further configured such that a pressure relief pipe is circumferentially connected to the outer side wall of the air intake cylinder, and a pressure relief valve is installed inside the pressure relief pipe.

[0012] The present invention is further configured such that the pressure relief valve includes a valve core and a valve plug, a set of pressure relief holes are circumferentially arrayed on the side wall of the pressure relief pipe, the valve plug is fixedly installed in the end of the pressure relief pipe away from the air intake cylinder, a compression spring is fixedly connected to the end of the valve plug near the air intake cylinder, and the valve core is slidably sleeved in the pressure relief pipe.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model installs a pneumatic rotating component inside the air inlet chamber and a turning paddle inside the carbon bed. When hot nitrogen enters the carbon bed from the air inlet chamber, it drives the pneumatic rotating component to rotate, which in turn drives the turning paddle to rotate, thereby continuously turning the activated carbon in the carbon bed and ensuring that all activated carbon particles can be desorbed by the hot nitrogen.

[0015] 2. This utility model installs an anemometer inside the outlet of the desorption chamber. The rotation speed of the anemometer determines the airflow velocity at the outlet of the desorption chamber. When pollutant molecules in the pores of activated carbon enter the gas phase, the limiting and throttling effect of the activated carbon on the hot nitrogen on the carbon bed decreases, thereby changing the airflow velocity at the outlet of the desorption chamber. The desorption status of the activated carbon is judged based on the airflow velocity.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please see Figures 1 to 4This invention relates to an activated carbon adsorber for hot nitrogen desorption and regeneration of waste gas treatment. It includes an inlet chamber 1 and a desorption chamber 2. A pneumatic rotating assembly 101 is installed inside the inlet chamber 1, and an agitator 201a is installed inside the carbon bed 201. When hot nitrogen enters the carbon bed 201 from the inlet chamber 1, it drives the pneumatic rotating assembly 101 to rotate, which in turn drives the agitator 201a to rotate, thus continuously agitating the activated carbon in the carbon bed 201, ensuring that all activated carbon particles are desorbed by the hot nitrogen. An anemometer 202 is installed at the outlet of the desorption chamber 2. The rotation speed of the anemometer 202 determines the airflow velocity at the outlet of the desorption chamber 2. When pollutant molecules in the activated carbon pores enter the gas phase, the restrictive effect of the activated carbon on the hot nitrogen decreases, thus changing the airflow velocity at the outlet of the desorption chamber 2. The desorption status of the activated carbon is determined based on the airflow velocity.

[0028] Specifically, the outlet end of the air inlet chamber 1 is installed at the air inlet end of the desorption chamber 2. A pneumatic rotating assembly 101 is installed inside the air inlet chamber 1. A carbon bed 201 is sleeved inside the desorption chamber 2. A set of vent holes is opened at the lower end of the carbon bed 201. An agitator 201a is rotatably installed inside the carbon bed 201. The agitator 201a is connected to the pneumatic rotating assembly 101. An anemometer 202 is installed inside the air outlet pipe of the desorption chamber 2.

[0029] Furthermore, the pneumatic rotation assembly 101 includes a pneumatic propeller sleeve 101a and a pneumatic propeller shaft 101b. The pneumatic propeller sleeve 101a includes an outer ring clamp 101a-1 and an inner shaft clamp 101a-2. The inner shaft clamp 101a-2 is fitted inside the outer ring clamp 101a-1 and is fixedly connected to the outer ring clamp 101a-1 through a connecting arm. The outer ring clamp 101a-1 is fixedly installed on the inner wall of the air intake chamber 1. The middle section of the pneumatic propeller shaft 101b is rotatably installed inside the inner shaft clamp 101a-2. A set of blades 101b-1 are axially arrayed and fixed on the outer side of the inner shaft clamp 101a-2 away from the carbon bed 201. After hot nitrogen enters the air intake chamber 1, it drives the blades 101b-1 to rotate, and the blades 101b-1 drive the pneumatic propeller shaft 101b.

[0030] Furthermore, a tumbling paddle shaft hoop 201b is fixedly provided at the upper end of the carbon bed 201, and the rotating shaft at the upper end of the tumbling paddle 201a is rotatably sleeved in the tumbling paddle shaft hoop 201b.

[0031] Furthermore, a transmission key 101b-2 is fixed on the outer side of the inner shaft hoop 101a-2 near the carbon bed 201. A transmission groove 201a-1 is opened at the upper end of the agitator 201a. The transmission key 101b-2 is sleeved in the transmission groove 201a-1. The pneumatic propeller shaft 101b achieves rapid transmission connection with the agitator 201a through the cooperation of the transmission key 101b-2 and the transmission groove 201a-1.

[0032] Furthermore, the outer side of the upper end of the carbon bed 201 is threaded onto the inner side of the air outlet end of the air inlet cylinder 1, which facilitates the installation of the carbon bed 201 inside the air inlet cylinder 1.

[0033] The operation process in this embodiment is as follows:

[0034] The activated carbon to be desorbed is placed in the carbon bed 201, and the carbon bed 201 is threaded into the air inlet chamber 1. At the same time, the transmission groove 201a-1 on the agitator 201a is aligned with the transmission key 101b-2 at the lower end of the pneumatic propeller shaft 101b. The desorption chamber 2 is then fitted onto the outside of the carbon bed 201 and connected to the air inlet chamber 1. Hot nitrogen is introduced into the air inlet chamber 1. The hot nitrogen drives the blade 101b-1 to rotate, and the blade 101b-1 drives the pneumatic propeller shaft 101b, thereby causing the agitator 201a to rotate, so that all activated carbon particles can be desorbed by the hot nitrogen.

[0035] Example 2

[0036] Please see Figures 1 to 5 Based on Embodiment 1, the air intake chamber 1 also includes a pressure relief pipe 102, through which the high-pressure gas in the air intake chamber 1 is discharged to prevent the air intake chamber 1 from rupturing due to excessive pressure.

[0037] Specifically, the outer sidewall of the air intake cylinder 1 is circumferentially connected with a pressure relief pipe 102, and a pressure relief valve 102a is installed inside the pressure relief pipe 102.

[0038] Furthermore, the pressure relief valve 102a includes a valve core 102a-1 and a valve plug 102a-2. A set of pressure relief holes 102b are circumferentially arrayed on the side wall of the pressure relief pipe 102. The valve plug 102a-2 is fixedly installed in the end of the pressure relief pipe 102 away from the air intake chamber 1. A compression spring 102a-3 is fixedly connected to the end of the valve plug 102a-2 close to the air intake chamber 1. The valve core 102a-1 is slidably sleeved in the pressure relief pipe 102. The high-pressure gas in the air intake chamber 1 pushes the valve core 102a-1 to move, causing the valve core 102a-1 to squeeze the compression spring 102a-3. When the valve core 102a-1 reaches the pressure relief hole 102b, the high-pressure gas is discharged from the pressure relief hole 102b.

[0039] The operation process in this embodiment is as follows:

[0040] When the air pressure in the air intake chamber 1 is too high, the high-pressure gas pushes the valve core 102a-1 to move, causing the valve core 102a-1 to squeeze the compression spring 102a-3. When the valve core 102a-1 reaches the pressure relief hole 102b, the high-pressure gas is discharged from the pressure relief hole 102b, thereby achieving the function of pressure relief.
