[0017] The beneficial effects of this utility model embodiment are as follows:

[0018] (I) A portable activated carbon adsorption device includes a mobile vehicle body, an adsorption tank, and an air distribution cone. The adsorption tank is located at the top of the mobile vehicle body, and an activated carbon core is detachably installed inside the adsorption tank. The air distribution cone is located at the bottom of the adsorption tank, with its apex facing upwards. One end of the air inlet pipe extends into the adsorption tank, with its opening facing the apex of the air distribution cone. The waste gas entering the adsorption tank first impacts the top of the air distribution cone, and then diffuses along the inclined cone surface into a uniformly rising airflow. This avoids disordered turbulent flow of the gas and ensures that the waste gas penetrates the entire cross-section of the activated carbon core in a laminar flow state, thereby improving the utilization rate of the activated carbon and delaying the rate of local saturation. At the same time, uniform air distribution reduces airflow resistance, stabilizes the internal air pressure of the adsorption tank during the movement of the mobile vehicle body, and enhances the operational reliability of the device.

[0019] (ii) Furthermore, support legs are provided at the bottom of both sides of the adsorption tank, and a vent pipe is also provided at the bottom of the adsorption tank. The vent pipe is connected to the inside of the adsorption tank and is equipped with a vent ball valve. By opening and closing the vent pipe at the bottom of the adsorption tank, the liquid accumulated in the tank can be completely drained when the equipment is stopped or maintained, preventing water from corroding the tank and soaking the activated carbon core, which would lead to a decrease in adsorption performance and extend the service life of the adsorption tank.

[0020] (III) Furthermore, a flexible hose is attached to the end of the air inlet pipe away from the adsorption tank, and hose supports are installed on the front and rear tops of the mobile vehicle body near the end of the air inlet pipe. Specifically, a quick-release interface is provided at the end of the air inlet pipe away from the adsorption tank, and the flexible hose is attached to the quick-release interface. The quick-release interface and the hose's connection to the air inlet pipe improve the equipment's working efficiency; at the same time, the hose supports support the hose, reducing the impact of bending caused by the hose's own weight on the gas delivery efficiency within the hose, thus improving working efficiency.

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] First embodiment:

[0027] like Figure 1As shown, a portable activated carbon adsorption device includes a mobile vehicle body 100, an adsorption tank 200, and an air distribution cone 300. Wheels 101 are rotatably connected to the four corners of the bottom of the mobile vehicle body 100. Specifically, the wheels 101 are omnidirectional wheels, and telescopic rods are provided at the four corners of the bottom of the mobile vehicle body 100. The wheels 101 are rotatably connected to the telescopic rods, allowing the height of the mobile vehicle body 100 to be freely adjusted. The adsorption tank 200 is located at the top of the mobile vehicle body 100, and an activated carbon core 201 is detachably disposed inside the adsorption tank 200. Specifically, a detachable tank cover 202 is provided at the top of the adsorption tank 200. For example, two activated carbon cores 201 are disposed inside the adsorption tank 200, and a mounting plate 203 is provided inside the adsorption tank 200. The bottom ends of the two activated carbon cores 201 pass through the mounting plate 203, and the top ends of the activated carbon cores 201 are engaged with the mounting plate 203. An exhaust pipe 204 is provided at the top of the adsorption tank 200, and the exhaust pipe 204 connects to the inside of the adsorption tank 200. An air inlet pipe 205 is also provided on the side of the adsorption tank 200, and the air inlet pipe 205 connects to the inside of the adsorption tank 200. For example, an exhaust ball valve 206 is provided on the exhaust pipe 204, and an air inlet ball valve 207 is provided on the air inlet pipe 205.

[0028] like Figure 1 As shown, the gas distribution cone 300 is located at the bottom of the adsorption tank 200, with its apex facing upwards. Specifically, the apex of the gas distribution cone 300 faces the middle of the two activated carbon cores 201, and the angle between the inclined conical surface of the gas distribution cone 300 and the ground is 17°. One end of the air inlet pipe 205 extends into the adsorption tank 200, with its opening facing the apex of the gas distribution cone 300.

[0029] like Figure 1 As shown, furthermore, support legs 208 are provided at the bottom of both sides of the adsorption tank 200, and a vent pipe 209 is provided at the bottom of the adsorption tank 200. The vent pipe 209 connects to the inside of the adsorption tank 200, and a vent ball valve 210 is provided on the vent pipe 209. By opening and closing the vent pipe 209 at the bottom of the adsorption tank 200, the accumulated liquid in the tank can be completely drained when the equipment is stopped or maintained, preventing water from corroding the tank and soaking the activated carbon core 201, which would lead to a decrease in adsorption performance and extend the service life of the adsorption tank 200.

[0030] like Figure 1As shown, furthermore, a flexible hose is snapped into the end of the air inlet pipe 205 away from the adsorption tank 200, and flexible hose supports 104 are provided on the top of the front and rear sides of the mobile vehicle body 100 near the end of the air inlet pipe 205. Specifically, a quick-release interface is provided at the end of the air inlet pipe 205 away from the adsorption tank 200, and the flexible hose is snapped into the quick-release interface. The snap-fit ​​design of the flexible hose with the air inlet pipe 205 through the quick-release interface improves the working efficiency of the equipment; at the same time, the flexible hose support 104 supports the flexible hose, reducing the impact of bending caused by the flexible hose's own weight on the gas delivery efficiency within the flexible hose, thus improving working efficiency.

[0031] like Figure 1 and Figure 2 As shown, furthermore, a trolley handle 102 is provided at the end of the mobile vehicle 100 away from the air intake pipe 205, and auxiliary handles 103 are provided on the front and rear sides of the end of the mobile vehicle 100 near the air intake pipe 205. The trolley handle 102 and the auxiliary handles 103 work together. The trolley handle 102 provides the main thrust to achieve linear movement, while the front and rear auxiliary handles 103 located on the side of the air intake pipe allow a single person to adjust the lateral position of the equipment by pulling it laterally, which facilitates operation or obstacle avoidance in narrow spaces and improves mobility.

[0032] like Figure 2 As shown, the adsorption tank 200 is further equipped with a pressure relief pipe 211, which connects to the adsorption tank 200. An automatic exhaust valve 212 is installed on the pressure relief pipe 211. The automatic exhaust valve 212 monitors the pressure changes inside the adsorption tank 200 and instantly releases pressure when the pressure inside the adsorption tank 200 becomes abnormal due to activated carbon saturation or temperature fluctuations, preventing tank deformation or seal failure. Simultaneously, it automatically discharges air trapped during the initial operation, ensuring the adsorption efficiency of the activated carbon core 201 and improving the safety and reliability of the device.

[0033] like Figure 2 As shown, the pressure relief pipe 211 is further equipped with a pipe sight glass 213. The airflow status through the pressure relief pipe 211 can be directly observed through the pipe sight glass 213: when the activated carbon core 201 is saturated, the sight glass shows that the airflow is turbid and the flow rate is slowed down, and the filter element needs to be replaced; if the automatic exhaust valve 212 is abnormally opened, it can be checked immediately whether it is a blockage or mechanical failure.

[0034] In operation, this embodiment is as follows:

[0035] The operator adjusts the equipment to the appropriate height by adjusting the telescopic rods at the four corners of the bottom of the mobile vehicle 100, and then pushes it to the target work position. The hose is then connected to the quick-release interface of the air inlet pipe 205 and fixed to the hose bracket 104. The air inlet ball valve 207 is opened to allow VOCs-containing waste gas to enter the air inlet pipe 205 through the hose. The waste gas vertically impacts the top of the air distribution cone 300 from the end of the pipe, and then spreads evenly along the inclined cone surface, simultaneously penetrating the adsorption areas of the two activated carbon cores 201. The purified gas is discharged through the exhaust pipe 204 at the top. During operation, the airflow status is monitored in real time through the pipe sight glass 213. When the pressure inside the adsorption tank 200 rises abnormally, the automatic exhaust valve 212 opens to release pressure. After the operation is completed, the air inlet ball valve 207 and the exhaust ball valve 206 are closed, the vent ball valve 210 is opened to drain the water accumulated at the bottom of the tank, and finally the activated carbon core 201 is pulled upward to detach it from the mounting plate 203 to complete the replacement.

[0036] In this embodiment, the waste gas entering the adsorption tank 200 first impacts the top of the gas distribution cone 300, and then diffuses along the inclined cone surface into a uniformly rising airflow. This avoids disordered turbulence of the gas and ensures that the waste gas penetrates the entire cross-section of the activated carbon core 201 in a laminar flow state, improving the utilization rate of the activated carbon and delaying the rate of local saturation. At the same time, uniform gas distribution reduces airflow resistance, making the internal air pressure of the adsorption tank 200 stable during the movement of the moving vehicle 100, thus enhancing the reliability of the device operation.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
