Abstract

Belonging to flue gas purification devices, the invention especially discloses a wet-type sintering desulfurization flue gas deep purification device, i.e. a device using the wet-type sintering desulfurization flue gas purification technology. The purification device includes a shell that is installed at the upper part of a desulfurization tower and is a part of the desulfurization tower body. The device is characterized in that: the inside of the shell is equipped with vertically mounted precipitation anode tube bundles and corona electrodes. The precipitating electrode tube bundles are supported by tube bundles inside the tower and fixed in the shell. The upper and lower ends of the corona electrodes are respectively connected to corona electrode small beams at the upper side and lower side of a corona electrode large beam, two ends of which are hung on a hanging rod in a side tube. A flushing instrument and an upper gas chamber are disposed over the precipitation electrode, the lower part of the shell is equipped with a gas distribution instrument, and a lower gas chamber is disposed between the precipitation electrode and the gas distribution instrument. A tower body platform outside the shell is provided with insulation boxes and transformers. The device can effectively remove micro-fine dust, acidic fog drops, nitrogen oxides, heavy metals, sulfates and other harmful substances from flue gas, and the removal rate can reach over 90%.

Description

technical field [0001] The invention belongs to a flue gas purification device, in particular to a device using the wet sintering desulfurization flue gas deep purification technology. Background technique [0002] There are many studies on mechanical demisters at home and abroad, but none of them can effectively solve the removal of fine dust, acid mist and other pollutants. Domestic studies on the use of demisters to remove dust and acid mist are basically blank; there is no effective control of dust and sulfuric acid mist in power plants and steel mills in my country, and there is a lack of specific operating parameters, power parameters and structure of demisters A study of the influence of parameters on the removal of pollutants by a mist eliminator. Contents of the invention [0003] In order to overcome the poor effect of existing demisters on pollutant removal, the present invention provides a deep purification device for wet sintering desulfurization flue gas, whi...
