Problems solved by technology
However, due to the high flue gas flow rate in the system, the flue gas contains a large number of large-size particles, and the flat tube type mist eliminator will cause local blockage, resulting in uneven distribution of flue gas flow rate, which will affect the use of the downstream roof type mist eliminator. effect, resulting in poor defogging effect of the demister and failing to meet the national environmental protection requirements
In addition, due to the surface tension factor, the uneven coverage of the flushing water film, the elastic collision between the liquid droplets and the plate, and the re-mixing into the flue gas are one of the key reasons for the decline in the demisting efficiency.

The flat plate pneumatic combined type demisting separation device comprises a cylinder body, a first demisting device and a second demisting device; the cylinder body comprises a top cylinder cylindrical body and a bottom hexagonal prism cylindrical body, the top cylinder cylindrical body is communicated with the bottom hexagonal prism cylindrical body, the first demisting device is arranged inside the bottom hexagonal prism cylindrical body, and the second demisting device is arranged inside the top cylinder cylindrical body. The flat plate pneumatic combined type demisting separation device has the advantages of being simple in structure, practical, convenient to operate, low in cost and convenient to promote and popularize.
Description
technical field [0001] The invention relates to a flat-plate pneumatic combined demisting and separating device, which belongs to the field of wet flue gas desulfurization and demisting devices. Background technique [0002] Limestone-gypsum wet flue gas desulfurization technology is currently the main technical measure used in my country to control flue gas pollution containing a large amount of sulfur dioxide emitted by coal-fired power plants. This technology is the most mature and widely used desulfurization technology at home and abroad, and its domestic application has reached above 95. Limestone-gypsum wet flue gas desulfurization process technology is to use limestone desulfurizer to spray and absorb coal-fired boiler flue gas containing sulfur dioxide harmful gas, and to purify flue gas by absorbing harmful gas through desulfurizer slurry and flue gas contact reaction. [0003] There are still many mist and dust in the purified flue gas after spraying and absorption...
