Abstract

The invention discloses a mechanism for extracting dust in desulfurized flue gas, a dust measuring device and method. The dust extracting mechanism comprises a flue gas mixing box, a flue gas conveying and measuring assembly, a cooling assembly, a cleaning assembly and a drying assembly, wherein the flue gas conveying and measuring assembly is installed on the side face of the flue gas mixing boxand used for conveying flue gas to the flue gas mixing box and measuring the flow of the conveyed flue gas; the cooling assembly is installed on the side, away from the flue gas conveying and measuring assembly, of the flue gas mixing box and used for cooling flue gas in the flue gas mixing box to form dew; the cleaning assembly is communicated with the flue gas mixing box and used for cleaning dew dripped out of the flue gas mixing box to form sewage; and the drying assembly is used for filtering and drying the sewage to obtain dust. The mechanism has the beneficial effects that the minimum amount of dust brought out by the flue gas can be measured, whether the flue gas contains the dust or not can be verified, and the content of the dust in the flue gas can be measured.

Description

technical field [0001] The invention relates to the technical field of measuring equipment, in particular to a mechanism for extracting dust from desulfurization flue gas, a dust measuring device and a method. Background technique [0002] Coal-fired power plant boiler flue gas enters the desulfurization tower after bag dust removal and denitrification. After wet desulfurization, the clean flue gas enters the flue through the demisting device at the upper end of the desulfurization tower, and is discharged into the sky through the chimney. When the ambient temperature is low, it often forms a white tail, commonly known as "big white feather", which is very spectacular. [0003] For a long time, there have been two schools of thought in the academic circle: 1. The big white feather is smoke. After being discharged from the chimney, it encounters the cold air outside to cool down. The moisture in the smoke forms small mist droplets, and countless small mist droplets form " 2....
