In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] Combined with Figures 1 to 4 A production testing machine for a molecular sieve filter substrate shown in the figure includes: a chassis 1, a substrate mounting seat 2, and a heating unit 6. Among them, support feet are provided at the lower end of the chassis 1, and pulleys can also be provided on the support feet to further facilitate movement. The substrate mounting seat 2 is used to mount the substrate unit, and the substrate mounting seat 2 is mounted on the chassis 1.

One side of the heating unit 6 is connected to one side of the air chamber 17 through a connecting pipe 7, and the other side of the heating unit 6 is also connected to the other side of the air chamber 17 through a pipe unit. A fan connection port 12 is provided on the pipe unit; a molecular sieve filter substrate 8 is provided inside the substrate unit in this embodiment. In this embodiment, by mounting the substrate mounting seat 2 and the heating unit 6 on the chassis 1, the equipment can be conveniently placed at the production site for use by moving the chassis 1. Moreover, the substrate mounting seat 2 of this production testing machine can be used to mount the substrate unit, so that the waste gas can be introduced into the air chamber 17, enabling the waste gas to flow through the substrate unit for filtration, thereby testing the filtration effect. Moreover, hot air can also be introduced into the air chamber 17 through the heating unit 6 to desorb the substrate unit, thereby testing the desorption effect. The whole structure is relatively simple and convenient to move, suitable for production site testing and demonstration, and the testing operation is more convenient.

[0022] The pipeline unit of this embodiment includes a first pipeline 13 and a second pipeline 14. One end of the first pipeline 13 is connected and communicated with the air chamber 17, and one end of the second pipeline 14 is connected and communicated with the heating unit 6. The other ends of the first pipeline 13 and the second pipeline 14 are connected with a tee joint. The fan connection port 12 is located on the tee joint. A first butterfly valve 15 is arranged at the connection of the first pipeline 13 and the tee joint, and a second butterfly valve 16 is arranged at the connection of the second pipeline 14 and the tee joint. The blower is connected through the fan connection port 12. The waste gas is pumped into the first pipeline 13 by the blower. At this time, the second butterfly valve 16 is in the closed state, and the first butterfly valve 15 is in the open state. The waste gas enters the air chamber 17, so that the waste gas flows through the substrate unit for filtration testing. When the substrate unit is saturated with adsorption, the first butterfly valve 15 is closed, and the second butterfly valve 16 is opened. At the same time, the air inlet of the blower is separated from the waste gas end, and fresh air is pumped into the heating unit 6, so that the air is heated and enters the air chamber 17 through the connecting pipe 7, so that the substrate unit is heated and desorbed, so as to test the regeneration adsorption capacity.

[0023] It should be noted that the upper end of the air chamber 17 of this embodiment is open, and a filter net 11 is covered on the opening, which can prevent impurities such as large particles from entering the substrate unit.

[0024] The upper edge of the upper end of the substrate mounting seat 2 of this embodiment is provided with a first mounting ring 9. The substrate unit includes a filter box body 3. The lower end of the filter box body 3 is provided with a second mounting ring 10 corresponding to the first mounting ring 9.

An exhaust hood 4 is installed at the upper end of the filter box body 3, and an exhaust port 5 is arranged on one side of the exhaust hood 4. The filter box body 3 can be conveniently installed on the substrate mounting seat 2, and can be disassembled and replaced at the same time, so as to facilitate assembly and testing at the production site, and the operation is more convenient.

[0025] The filter box body 3 of this embodiment is filled with a molecular sieve filter substrate 8. The upper end of the filter box body 3 is provided with a substrate insertion port, and the lower end is provided with a substrate support rod.

The lower end of the filter box body 3 is connected and communicated with the air chamber 17 through an opening. The molecular sieve filter substrate 8 can be conveniently taken out or placed in the filter box body 3 for use and testing, and the operation is convenient.

[0026] It should be noted that the heating unit 6 of this embodiment includes a heating box body, and a plurality of heating tubes are installed in the heating box body. The air in the heating box body can be heated by the plurality of heating tubes, so as to facilitate the introduction of the heated air into the filter box body 3 for desorption.

[0027] It is also worth noting that the inner walls of the air chamber 17 of this embodiment are respectively provided with a first air inlet 18 and a second air inlet 19. The first air inlet 18 is communicated with the first pipeline 13, and the second air inlet 19 is communicated with the connecting pipe 7. A check valve plate 20 located on the inner wall of the air chamber 17 is hinged at the upper end of the second air inlet 19. Under gravity, the check valve plate 20 can close the second air inlet 19. At the same time, when testing the filtration performance, the air flow can tightly press the check valve plate 20 against the second air inlet 19 to prevent waste gas from entering the heating unit 6. When testing the desorption and regeneration ability of the molecular sieve filter substrate 8, hot air can open the check valve plate 20 and blow it into the air chamber 17. The structure is simple and the testing efficiency is better.
