Fly ash recovery device for environmental-protection project

Abstract

The invention discloses a fly ash recovery device for an environmental-protection project. The fly ash recovery device comprises a smoke pipe, wherein a cylindrical box body is fixedly mounted in thesmoke pipe; the middles of the upper and lower end surfaces of the box body are both provided with first shaft holes; first vertical shafts are arranged in the first shaft holes; the first vertical shafts can be slid up and down along the first shaft holes; a cross rod is fixedly mounted in the smoke pipe; the middle of the bottom of the cross rod is fixedly provided with a vertical elastic telescopic rod; the lower end of a movable rod of the elastic telescopic rod is movably connected with a bearing at the upper ends of the first vertical shafts. The fly ash recovery device is ingenious in structure, is used for simultaneously providing power for the rise of flue gas and the pressurization of desulfurized slurry in a water inlet pipe through ingenious drive design, also has the functionof automatically controlling the rise speed of the flue gas, and can be used for effectively helping to remove smoke dust and sulfur dioxide in the glue gas; the fly ash recovery device is mounted inthe interior of a chimney, basically does not occupy other space, and is low in construction cost, and the fly ash recovery device has great help to ameliorate air quality after being popularized.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, in particular to a fly ash recycling device for environmental protection engineering. Background technique [0002] Fly ash is the tiny ash particles emitted during the combustion of fuels, mainly coal. Its particle size is generally between 1 and 100 μm. It belongs to hazardous waste, also known as fly ash or soot. Fly ash contains harmful substances such as soot and sulfur dioxide. [0003] The coal used in small and medium-sized boilers and kilns usually has a high sulfur content, and a large amount of harmful substances will be discharged during the combustion process, especially the discharge of smoke and sulfur dioxide, which pollutes the atmospheric environment very seriously. The content of soot and sulfur dioxide has put forward the control standard requirements, and the standards are being gradually raised, such as soot ≤ 50mg / Nm3, sulfur dioxide ≤ 100mg / Nm3...
