Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 As shown, a device for collecting and filtering metal dust vapor, including a trumpet-shaped collection port 1, a suspension arm feeder 2, a side air inlet 3, a dust removal chamber 4, a negative pressure fan 5, and a gas shock hammer 7 , high-efficiency dust removal cylinder 8 and streamlined spoiler 9. The fan 5 provides a negative pressure environment for the whole equipment, so that the dust-laden gas enters the interior of the dust removal chamber 4 through the trumpet-shaped collection port 1 through the suspension arm 2 and the side wind inlet 3, and the air entering from the suspension arm 2 and the side wind inlet 3 The dusty gas intersects with each other, and the metal particles inside collide, which reduces the speed of the dust particles, and then the dusty gas continues to hit the streamlined spoiler 9, wh...

Abstract

The invention discloses a device for collecting and filtering steam of metal dust. The device comprises a collecting hole, an overhang arm feeder, a dust removing chamber, a gas vibrating hammer, lateral gas inlets, an intercepting plate, an efficient dust removing cylinder and a gas outlet. After entering the dust removing chamber through an overhang pipeline feeder, dusty gas flows together with dusty gas entering from the side surface, and dust particles moving in different directions collide, so that the kinetic energy is reduced, the speed is decreased, the time of contact between dust and the dust removing cylinder is relatively long, and the dust removing efficiency is increased; by virtue of the relatively low speed of dust, the impact force caused by dust to the cylinder wall is beneficially reduced, and the noise is reduced; meanwhile, by virtue of horizontal wind force caused by lateral inlet air, the moving range of dust in the horizontal direction is relatively large. By virtue of theories that the momentum is constant, and the kinetic energy is reduced during the collision of dust, a vertical air inlet and a lateral air inlet are combined for use, and the streamlined intercepting plate is utilized, so that the defect that the utilization rate of dust removing equipment is low is solved, the noise during the use of the equipment is effectively reduced, and the damage to an equipment body is reduced.

Description

technical field [0001] The invention relates to the technical field of collecting and filtering metal dust vapor, in particular to a device for collecting and filtering metal dust vapor, which has the characteristics of high efficiency and low noise. Background technique [0002] Lead-based alloys are popular coolants for subcritical drive reactors due to their good proliferation and transmutation properties. During melting and refueling of the circuit, some lead vapor will inevitably leak into the air. Lead vapor can cause damage to the respiratory system and nervous system of personnel, and may float into the equipment to cause danger; therefore, research on efficient metal dust collection and removal The unit provides a solid foundation for maintaining a well-functioning reactor environment. [0003] Methods to remove metal dust include gravity dust removal, wet dust removal, filter dust removal, etc. However, due to the small particle size of metal dust (about 100nm to ...
