Flue gas self-suction type environment-friendly flue gas purification device

Abstract

The invention discloses a flue gas self-suction type environment-friendly flue gas purification device. The device comprises a flue gas and dust particle filtering mechanism, a flue gas purifying mechanism and an exhaust fan; the flue gas dust particle filtering mechanism and the exhaust fan are fixedly mounted at the two ends of the flue gas purifying mechanism respectively; flue gas enters fromthe pipe orifice of a flue gas inlet pipe and drives sleeved fan blades to rotate; the sleeved fan blades rotate at one end in the flue gas inlet pipe to generate a downward cyclone, so that dust particles with relatively large particle sizes in the flue gas are settled; the dust falls into a dust outlet hopper through a dust outlet to be collected; the dust particles with relatively large particle sizes are prevented from entering a purification filter element along with the flue gas; the dust particles with relatively large particle sizes are prevented from entering the purification filter element; the phenomena that the purification filter element is damaged and the purification effect is affected are avoided; through clamping of a cambered surface pulley and a semicircular guide column, installation is more convenient and more labor-saving, meanwhile, the semicircular guide column plays a guiding role, and when the pull-out purification filter element is pushed into a purificationfilter element installation shell, the pull-out purification filter element is more stable and more accurate in positioning.

Description

technical field [0001] The invention relates to the technical field of flue gas purification equipment, in particular to a flue gas self-suction environment-friendly flue gas purification device. Background technique [0002] The smoke and dust purifier is a high-efficiency air purifier designed for industrial waste gas, smoke and dust. Air purification system. Widely used in machinery, hardware, electronic appliances, optoelectronics, chemicals, tobacco, pharmaceuticals, food, biology and other industries and other places polluted by smoke, smoke and dust. [0003] The flue gas will contain a large amount of dust particles. In the prior art, when the self-priming flue gas purification device absorbs and purifies the flue gas, it only sucks the dust particles in the flue gas into the purification filter element for purification and filtration. Dust particles with a large particle size will cause losses to the purification filter element and affect the purification effect o...

[0003] The flue gas will contain a large amount of dust particles. In the prior art, when the self-priming flue gas purification device absorbs and purifies the flue gas, it only sucks the dust particles in the flue gas into the purification filter element for purification and filtration. Dust particles with large particle size will cause losses to the purification filter element, affecting the purification effect of the purification filter element on the flue gas. At the same time, the installation and disassembly of the purification filter element of the existing self-priming flue gas purification device is inconvenient.
