Flue gas exhaust system

Abstract

The invention relates to the technical field of smoke exhaust devices, in particular to a flue gas smoke exhaust system, an arranged liquid supply device can pump alkali liquor in an alkali liquor box to a guide pipe through a metering pump, and the alkali liquor enters a water tank through the guide pipe and is sprayed out from a spraying head of a spraying device, so that harmful gas in flue gas is removed; alkali liquor is discharged from the outlet end of a guide pipe and falls onto an upper water wheel, so that a rotating shaft is driven to rotate through the upper water wheel, a first bevel gear on the rotating shaft drives an induced draft fan on a vertical shaft to rotate through the matching effect with a second bevel gear, and treated flue gas is attracted to be discharged out of the spray tower; the driving device is triggered after the water level of alkali liquor in the water tank reaches a certain height and discharges the alkali liquor from the drain pipe so as to drive the lower water wheel, so that the cleaning device can clean the filter membrane, and the driving device can ensure that the liquid level of the alkali liquor in the water tank is maintained in a certain range while driving the cleaning device; the air inducing device is prevented from being influenced by the rotation of the upper water wheel caused by over-high water level.

Description

technical field [0001] The invention relates to the technical field of smoke exhaust devices, in particular to a flue gas smoke exhaust system. Background technique [0002] Flue gas refers to the gaseous substances that pollute the environment produced when coal and other fossil fuels are burned. These substances are usually discharged from flues or chimneys. The process of flue gas generation is mostly caused by insufficient utilization of fuel and incomplete combustion. Its components are nitrogen, carbon dioxide, oxygen, water vapor and sulfide, etc. The content of dust, slag and sulfur dioxide is less than 1%, and it must be emptied after being treated by a gas purification device to reduce environmental pollution. If the purification operation is not normal, carbon monoxide, nitrogen oxide and other harmful gases will be produced. [0003] At present, most flue gas treatment devices are complex in structure, high in cost, unstable in effect, and easily cause a lot of...
