[0015] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0016] Example:

[0017] The accompanying drawings illustrate a specific embodiment of a mobile RTO molecular sieve desorption device of the present invention. It mainly includes a device body 1, with an air inlet 2 and an air outlet 3 on both sides of the device body 1. A heating mechanism 4 is provided inside the air inlet 2. The heating mechanism 4 can be any one of an electric heating plate, an electric heating wire, or an electric heating tube, and is used to heat the air.

[0018] The device body 1 has an inner region 1a and an outer region 1b inside. The inner region 1a is located at the center inside the device body 1, and the outer region 1b surrounds the inner region 1a. The two sides of the inner region 1a are connected to the outer region 1b through a connecting region 1c, and the two sides of the outer region 1b are connected to the air inlet 2 and the air outlet 3, respectively.

[0019] A zeolite rotating cylinder 5 is installed in the inner layer region 1a of the device body 1. The upper and lower ends of the zeolite rotating cylinder 5 extend out of the device body 1 to the outside, and the portion extending to the outside is a closed structure. The zeolite rotating cylinder 5 is rotatably connected to the upper and lower ends of the device body 1 in a sealed manner. The upper and lower ends of the zeolite rotating cylinder 5 are respectively provided with a loading port 8 and a discharge port 9. The zeolite molecular sieve is loaded into the zeolite rotating cylinder 5 through the loading port 8 and discharged from the zeolite rotating cylinder 5 through the discharge port 9. Air can pass through the portion of the zeolite rotating cylinder 5 located inside the device body 1 and come into contact with the zeolite molecular sieve for desorption.

[0020] The zeolite rotating drum 5 is driven to rotate by the first motor 10. The output shaft of the first motor 10 is connected to the upper end of the zeolite rotating drum 5 through the first transmission belt 11. The first motor 10 is installed on the top of the device body 1.

[0021] A heat storage rotating cylinder 6 is provided in the outer layer region 1b of the device body 1. The upper end of the heat storage rotating cylinder 6 extends out of the device body 1 to the outside, and the part extending to the outside is a closed structure. The heat storage rotating cylinder 6 is rotatably connected to the upper end of the device body 1 in a sealed manner. The heat storage rotating cylinder 6 is filled with a heat storage layer. Air can pass through the part of the heat storage rotating cylinder 6 located inside the device body 1 and through the heat storage layer.

[0022] The heat storage drum 6 is driven to rotate by the second motor 12. The output shaft of the second motor 12 is connected to the upper end of the heat storage drum 6 through the second transmission belt 13. The second motor 12 is installed on the top of the device body 1.

[0023] Air inlet 2, heat storage drum 6, zeolite drum 5, and air outlet 3 are connected. Air enters from air inlet 2 and is heated into hot air, then passes through heat storage drum 6 and enters zeolite drum 5 to desorb the zeolite molecular sieve and is discharged from air outlet 3.

[0024] The bottom of the device body 1 is equipped with casters 7.

[0025] In the specific operation of this utility model, the zeolite molecular sieve saturated with adsorbed VOCs is filled into the zeolite rotating drum 5 through the feeding port 8; air enters from the air inlet 2, is heated by the heating mechanism 4, and then passes through the heat storage rotating drum 6. The air, together with the temperature accumulated in the heat storage layer of the heat storage rotating drum 6, is transferred to the zeolite rotating drum 5 to carry out the desorption and oxidation reaction of VOCs on the zeolite molecular sieve. Since the VOCs oxidation reaction is an exothermic reaction, the air temperature rises. Subsequently, the high-temperature air exchanges heat through the heat storage layer, causing the temperature of the heat storage layer to rise. Finally, the air is discharged from the air outlet 3.

[0026] The high-temperature heat storage layer on the air outlet side is driven by the second motor 12 to rotate with the heat storage drum 6 to the air inlet side, where it exchanges heat with the air and repeats the above operation; the zeolite molecular sieve in the zeolite drum 5 on the air outlet side is also driven by the first motor 10 to rotate to the air inlet side to completely desorb the zeolite. After all the zeolite molecular sieves in the zeolite drum 5 have been desorbed, the zeolite molecular sieves are discharged from the discharge port 9.

[0027] This device is only used for desorption and is not used frequently. It is lightweight and small in size, and can be used on-site via the casters 7.
