Detailed description of the invention
As shown in Fig. 1 ~ 5, formaldehyde catalyst extraction tool of the present utility model, for the catalyst in abstraction reaction device tubulation 1, reactor tubulation 1 includes many parallel arrangement of catalyst tubes 10, including the compression air supervisor 2, upper backup pad 3, lower supporting plate 4 and the catalyst collection cover 5 that set gradually from top to bottom, compression air supervisor 2 is horizontally disposed with and is connected to compressed gas source, and the bleed pressure of compressed gas source is be more than or equal to 0.2Mpa.
The downside of compression air supervisor 2 is connected to 6 (more than three) vertically arranged insertion pipes 6, insert pipe 6 one-tenth string to arrange, insert pipe 6 and be positioned on same vertical plane, insert and be arranged in parallel between pipe 6 and be provided with interval between adjacent insertion pipe 6, upper backup pad 3, lower supporting plate 4 also horizontally set and upper backup pad 3 are parallel with lower supporting plate 4, are provided with the suspension cord 7 for hanging traction between two ends and the compression air supervisor 2 of upper backup pad 3; Upper backup pad 3, lower supporting plate 4 material be nylon sheet.
Upper backup pad 3, lower supporting plate 4 are equipped with for the gripper shoe perforation 8 inserting pipe traverse, the shape of gripper shoe perforation 8 is suitable with the cross sectional shape inserting pipe 6, the quantity of gripper shoe perforation 8 on upper backup pad 3, lower supporting plate 4, position and the quantity of insertion pipe 6, position are corresponding, catalyst collection chamber it is provided with in catalyst collection cover 5, the upside of the front end of catalyst collection cover 5 is provided with upper cover plate 9, upper cover plate 9 is provided with mean for the cover plate perforation 11 of all of insertion pipe 6 traverse, and the material of upper cover plate 9 is also nylon sheet. The shape of cover plate perforation 11 is suitable with the cross sectional shape inserting pipe 6, and the quantity of cover plate perforation 11, position and the quantity of insertion pipe 6, position are suitable, are provided with sealing member, it is prevented that catalyst overflows from here between insertion pipe 6 and upper cover plate 9.
