Detailed description of the invention
As Fig. 1 ~ 5Shown in, a kind of instrument that extracts formaldehyde catalyst of the present invention, for the catalyst in abstraction reaction device tubulation 1, reactor tubulation 1 comprises the many parallel catalyst tubes 10 that arrange, comprise the compressed air supervisor 2, upper backup pad 3, lower supporting plate 4 and the catalyst collecting hood 5 that set gradually from top to bottom, compressed air supervisor 2 is horizontally disposed with and is connected with compressed gas source, and the bleed pressure of compressed gas source is more than or equal to 0.2Mpa.
Compressed air supervisor 2 downside is connected with 6 (more than three) vertical Inserting Tube 6 arranging, 6 one-tenth one row settings of Inserting Tube, Inserting Tube 6 is positioned on same vertical plane, between Inserting Tube 6, be arranged in parallel and adjacent Inserting Tube 6 between be provided with interval, upper backup pad 3, lower supporting plate 4 also horizontally set and upper backup pad 3 parallel with lower supporting plate 4, between the two ends of upper backup pad 3 and compressed air supervisor 2, be provided with the suspension cord 7 for hanging traction; The material of upper backup pad 3, lower supporting plate 4 is nylon sheet.
