Abstract
The invention discloses a device for recovering molybdenum powder particle in flues with filter screens. The device comprises a waste gas delivery channel and a dissipation tower arranged at the end of the waste gas delivery channel. At least three filter screens are arranged in the dissipation tower. The three filter screens are a first filter screen, a second filter screen and a third filter screen. The mesh size of the first filter screen is larger than the mesh size of the second filter screen, and the mesh size of second filter screen is larger than the mesh size of the third filter screen. An openable collection flap door is arranged opposite to the connection surface of the dissipation tower and the waste gas delivery channel. The materials for the first, second and third filter screens are all stainless steel wire screens. With the device provided by the invention, a phenomenon that a large amount of molybdenum powder dust is discharged with smoke dust is avoided, such that resource wasting is prevented, and a molybdenum powder material is saved.
Description
Technical field
The present invention relates to a kind of molybdenum powder and reclaim processing technique field, more particularly, relate to a kind of device utilizing filter screen to reclaim molybdenum powder particle in flue.
Background technology
Namely the production preorder of ammonium molybdate or Sodium orthomolybdate is by granular molybdenum powder finished product heated oxide, make molybdenum oxide, important in this heat-processed is exactly heat-up time and Heating temperature, the temperature of general molybdenum powder oxidation heating controls within 600 degrees Celsius, if do not controlled, under directly molybdenum powder being placed in the environment of high temperature, outer field molybdenum powder rapid oxidation can be caused, and the molybdenum powder being covered by internal layer is easily oxidized not exclusively, and molybdenum powder particle easily takes up by the rapid high temperature risen, entrain into flue dust outwards to get rid of, cause the waste of molybdenum powder material.So our company plans to arrange filtration unit in the flue getting rid of combustion exhaust, consider that the effect of once filtering has been not enough to filter effect, if and the mesh once filtered is too little will block flue, waste gas is caused not get rid of, if mesh is excessive, good filter effect can not be played again.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, applicant, through repeatedly putting into practice improvement, devises a kind of device utilizing filter screen to reclaim molybdenum powder particle in flue, and adopt multiple times of filtration, the mesh of each filtering net diminishes successively, realizes multilayer and repeatedly screens.
Technical scheme: in order to realize foregoing invention object, the technical solution adopted in the present invention is: a kind of device utilizing filter screen to reclaim molybdenum powder particle in flue, comprising: waste gas transfer passage and be arranged on the dissipation tower of waste gas transfer passage end.At least three road filtering nets are set in described dissipation tower, be respectively the first filtering net, the second filtering net and the 3rd filtering net, the mesh aperture of described first filtering net is greater than the mesh aperture of the second filtering net, the mesh aperture of described second filtering net is greater than the mesh aperture of the 3rd filtering net, and the opposite of described dissipation tower and waste gas transfer passage joint face arranges openable collection overhead door.
Further, the distance range between described first filtering net and the second filtering net is 70cm-80cm, and the distance range between described second filtering net and the 3rd filtering net is also 70cm-80cm.
Again further, the material of described first filtering net, the second filtering net and the 3rd filtering net is stainless steel and iron silk screen.
Further, the inwall of described dissipation tower arranges protuberance, and connecting portion is set to rectangular card flute profile, correspondingly, the edge of described first filtering net or the second filtering net or the 3rd filtering net is set to rectangular card dentation.
Beneficial effect: compared with prior art, its beneficial effect is in the present invention:
1, present invention, avoiding a large amount of molybdenum powder dust to be discharged together along with flue dust, cause the waste of resource, saved molybdenum powder material;
2, present invention, avoiding the shortcoming that once filtration cannot be arranged, first through the filtering net of thick some mesh, and then successively by the filtering net that mesh reduces gradually, so just can avoid the phenomenon of once filtering blocking mesh.
