Abstract

The invention relates to an absorption tower device with ultra-low emission of flue gas. Fog section and flushing water supply system, the inlet flue is connected to the lower part of the tower body, the flue gas discharge port is connected to the top of the tower body, and the tower body is coaxially arranged with a pneumatic desulfurization section and a smoke barrier from bottom to top. The water section, the tray dust removal section and the pneumatic high-efficiency dust removal and mist removal section, and the flushing water supply system can clean the tray dust removal section and the pneumatic high-efficiency dust removal and mist removal section. The contents of droplets, dust and various ions in the flue gas treated by the tower of this device have been greatly reduced, avoiding secondary pollution to the environment, and the device is not easy to scale, and will not The problem of secondary entrainment occurs. Through the strong mixing of flue gas and slurry, the desulfurization efficiency can reach more than 99%, meeting the requirements of ultra-low emissions.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a flue gas ultra-low emission absorption tower device and its application. Background technique [0002] Among the mainstream flue gas desulfurization technologies at home and abroad, wet desulfurization technology occupies a dominant position. Its main equipment is the absorption tower device. The flue gas treated by the absorption tower contains a large number of liquid droplets, and the dust and liquid droplets contain various Ions, along with the flue gas discharged into the atmosphere through the outlet, will cause secondary pollution to the environment. [0003] The current technology is mainly to add demisters on the top of the absorption tower. The mainstream demisters are mainly plate demisters and roof demisters. Such demisters are prone to fouling and secondary entrainment. , it is very difficult to reduce the dust concentration at the tower outlet an...
