Embodiment
[0110] see figure 1 , on the inclined vaporization cooling flue near the upper part of the converter hood, more than two flue gas sampling ports 26 are evenly arranged along the circumference of the vaporization cooling flue. Under the suction of the sampling fan 21, the high temperature converter flue gas is sampled from the flue gas Port 26, enter the flue gas cooler 11 through the converter flue gas sampling pipe 12 with jacket water cooling, and flow through the gap of the stainless steel ball bed with a particle size of 1 to 3 mm filled in the flue gas cooler 11 , and directly contact with stainless steel balls for heat exchange, at the same time, the condensable components in the flue gas are condensed and attached to the surface of the steel balls, and the soot particles brought in with the flue gas are also intercepted and captured by most of the steel ball bed .
[0111] After being cooled, intercepted and filtered by the bed of stainless steel balls, the concentrati...
