It is mainly composed of elements such as silicon and aluminum, and has a crystalline structure in which some atoms in the lattice are replaced or deleted to form channels and pores. The channel and pore size of the molecular sieve can be regulated according to demand, and are usually described in nanometer scale. This precise pore size allows the molecular sieve to selectively adsorb or exclude substances of specific molecules or molecular sizes, achieving the function of separation and purification. Molecular sieves can adsorb impurities, moisture, organic matter or metal ions in liquids or gases, and are characterized by high efficiency, high selectivity and regeneration.

[0022] See also Figure 1-4 The utility model provides an embodiment: a molecular adsorption catalytic device, including a molecular adsorption catalyst 6, a driving motor 10 and a reduction box 11 are installed on one side of the molecular adsorption catalyst 6, the output shaft end of the driving motor 10 is connected to the input end of the reduction box 11, the interior of the molecular adsorption catalyst 6 is arranged as a cylindrical inner cavity 7, a rotating component 12 is installed inside the cylindrical inner cavity 7 along the output shaft end of the reduction box 11, the rotating component 12 is composed of a hollow column 13 and a rotating leaf 15, a gas inner cavity 14 is arranged inside the hollow column 13, and a first exhaust pipe 21 is installed at a position connected to the gas inner cavity 14 in the middle of the side of the molecular adsorption catalyst 6.

[0023] There are three rotating pages 15, and the three rotating pages 15 are fixed in a circular array on the outside of the hollow column 13. An intermediate connecting hole 16 is opened on the hollow column 13, and a one-way flow tube is installed in the intermediate connecting hole 16 to prevent the filtered gas from reaching other positions through the intermediate connecting hole 16. However, the gas flowing in from the outside must be clean gas and is not blocked; the interior of the cylindrical inner cavity 7 is divided into three areas: an exhaust gas adsorption area 17, a high-temperature desorption area 18 and a low-temperature cooling area 19 by the rotating pages 15 on the rotating component 12. The exhaust gas adsorption area 17, the high-temperature desorption area 18 and the low-temperature cooling area 19 are filled with molecular sieves 20, and the exhaust gas adsorption area 17, the high-temperature desorption area 18 and the low-temperature cooling area 19 are cyclically converted.

[0024] An exhaust gas delivery pipe 5 is installed at a position on the molecular adsorption catalyst 6 that is connected to the exhaust gas adsorption area 17. The other end of the exhaust gas delivery pipe 5 is connected to the output end of the exhaust gas filter 4. The input end of the exhaust gas filter 4 is connected to the first air supply pipe 3. The other end of the first air supply pipe 3 is connected to the output end of the first blower 1. The input end of the first blower 1 is connected to the first exhaust pipe 2.

[0025] The first blower 1 draws exhaust gas through the first exhaust pipe 2 and transports it to the exhaust gas filter 4 through the first air supply pipe 3 for preliminary filtration. The filtered exhaust gas reaches the exhaust gas adsorption area 17 of the molecular adsorption catalyst 6 through the exhaust gas delivery pipe 5. The molecular sieve 20 adsorbs and purifies the exhaust gas. The exhaust gas then flows into the gas inner cavity 14 through the one-way flow pipe installed in the middle connecting hole 16 and is discharged through the first exhaust pipe 21.

The other end of the second air supply pipe 28 is connected to the output end of the second blower 26. The input end of the second blower 26 is connected to the second exhaust pipe 27.

[0029] After desorbing impurities, the high-temperature desorption zone 18 reaches the low-temperature cooling zone 19 under the operation of the driving motor 10. The second blower 26 draws external air through the second exhaust pipe 27 and transports it to the refrigerator 25 through the second air supply pipe 28 for refrigeration. The cooled air reaches the low-temperature cooling zone 19 through the cold air delivery pipe 8, so that the molecular sieve 20 is cooled.

[0030] As the output shaft of the drive motor 10 continues to move, the cooled low-temperature cooling zone 19 rotates to the exhaust gas adsorption zone 17 to adsorb the exhaust gas. The exhaust gas adsorption zone 17, the high-temperature desorption zone 18 and the low-temperature cooling zone 19 are cyclically switched to perform exhaust gas adsorption, high-temperature desorption and low-temperature cooling at the same time.
