The combined honeycomb zeolite molecular sieve has better adsorption properties and can improve the purification treatment effect of organic waste gas.

[0039] The clamping mechanism 6 includes an assembly card frame 61 and a reset slide groove 62 opened inside the assembly card frame 61, a wedge-shaped block 63 is slidably arranged at the bottom of the reset slide groove 62, a pull rod 65 is fixedly arranged on the top of the wedge-shaped block 63, a small spring 64 is sleeved at the connection between the pull rod 65 and the wedge-shaped block 63, a pull ring 66 is fixedly arranged on the top of the pull rod 65 passing through the assembly card frame 61, the wedge-shaped block 63 matches the reserved slot 7, and the assembly card frame 61 is fixedly set on the external splicing frame 4.

[0040] In the embodiment of the utility model, when two adjacent honeycomb zeolite molecular sieves are spliced, the inner splicing frame 5 of one of the honeycomb zeolite molecular sieves is inserted into the outer splicing frame 4 of the other honeycomb zeolite molecular sieve. During the insertion process, the wedge-shaped block 63 will be squeezed to slide into the reset slide groove 62 until the inner splicing frame 5 is completely inserted into the outer splicing frame 4.
