specific Embodiment approach 3

[0011] Embodiment 3: This embodiment is described with reference to FIG. 1 and FIG. 5 . The filter plate 1-3 of this embodiment is made of glass material, and the pore diameter Φ of the filter plate 1-3 is 4-7 μm. The pore size of the filter plate 1-3 is selected within this range, which can ensure that the palladium-carbon catalyst does not flow into the filtrate collector 5 with the liquid, thereby ensuring the complete separation of the palladium-carbon catalyst and the obtained product. Other components and connections are the same as those in the second embodiment.

The reactor 2 is firm joined with the filter 1 through the first pipe line 4, the filter 1 is connected with the nitrogen regulating bag 19 through the sixth pipe line18, the filter 1 is connected with the filtering liquid collector 5 through the second controlling valve 7, the filtering liquid collector 5 is firm joined with the nitrogen buffering tan 8 through the third pipe line 9 and nitrogen valve 10, the filtering liquid collector 5 is firm joined with the vacuum buffering tan 11 through the fourth pipe line 12 and the first vacuum valve 13, the vacuum buffering tan 11 is firm joined with the vacuum pump 14 through the fifth pipe line 16 and the second vacuum valve 15, the filter liquid collector 5 is firm joined with the liquid discharging valve 17, the filter 1 and filter liquid collector 5 are firm joined with the supporting rack. The product medium can be prevented from oxidation by using the filter device in this invention.

Description

Technical field: [0001] The invention relates to a filtering device for separating palladium-carbon catalysts, which belongs to the technical field of chemical industry; in particular, it relates to a filtering device for preventing oxidation and separating palladium-carbon catalysts. Background technique: [0002] In the process of chemical production, in order to make the chemical reaction proceed quickly and thoroughly, it is necessary to use solid catalysts. Palladium-carbon catalyst is often used in the process of hydrogenation reduction reaction. After the chemical reaction is over, the product must be separated from the palladium-carbon catalyst. During the separation process, it is often encountered that the obtained product is easily oxidized in the air medium and whether the separated palladium-carbon catalyst can problem of utilization. At present, a melting funnel is often used to separate the palladium carbon catalyst and the resulting product. Because the mel...
