Problems solved by technology

[0002] When recycling lead in waste, it is necessary to pass the lead-containing waste through a high-temperature furnace to achieve the purpose of easy lead and lead recovery. However, when this process is performed, a large amount of flue gas will be generated, and a large amount of Solid particles that are harmful to the human body. If there are a large number of fixed particles in the water and the chimney is directly discharged into the air, it will cause serious harm to the surrounding environment and personnel.

Embodiment Construction

[0015] The present invention will be further described in detail in conjunction with the accompanying drawings, but not as any limitation to the present invention.

[0016] Embodiment of the present invention: a flue gas dedusting method, the method is to use flue gas and solid dust under the same thrust to continuously change the movement direction of flue gas and fixed dust to cause different energy losses per unit weight of flue gas and fixed dust , and in the process of repeatedly changing the gravitational potential energy, when the initial kinetic energy lost per unit weight of the flue gas and fixed dust cannot overcome the gravitational potential energy, they will be deposited at the bottom of the exhaust pipe to separate the flue gas from the dust, thereby realizing the Air dust removal purpose.

[0017] Specifically, the exhaust tube is a bent structure and placed vertically. The angle of the exhaust tube at the bend is 30° to 60°. The flue gas and solid dust are dri...

Abstract

The invention discloses a flue gas dust-removing method which is characterized in that the motion directions of flue gas and fixed dust are continuously changed under same thrust, so that different energy loss of flue gas and fixed dust in unit weight can be caused; furthermore, in the event of repetitively changing gravitational potential energy, gravitational potential energy cannot be overcome by lost initial kinetic energy of flue gas and fixed dust in unit weight, therefore, flue gas and fixed dust can be deposited at the bottom of an exhaust cylinder; separation of flue gas from dust is realized, so that the purpose of removing dust from flue gas is realized; and the flue gas dust-removing method and device disclosed by the invention are convenient in structure, obvious in dust removing effect and good in practicability and economic efficiency.

Description

technical field [0001] The invention relates to a flue gas dedusting method and device, belonging to the technical field of grain production and processing. Background technique [0002] When recycling lead in waste, it is necessary to pass the lead-containing waste through a high-temperature furnace to achieve the purpose of easy lead and lead recovery. However, when this process is performed, a large amount of smoke will be generated, and the smoke contains a large amount Solid particles that are harmful to the human body, if there are a large number of fixed particles in the water and the chimney is directly discharged into the air, it will cause serious harm to the surrounding environment and personnel. Contents of the invention [0003] The object of the present invention is to provide a flue gas dedusting method and device, which can realize the deposition of solid particles in the flue gas and reduce air pollution, so as to overcome the deficiencies of the prior art...
