Vertical heat recovery coke oven supporting exhaust gas waste heat boiler flue gas emission system

Abstract

The utility model embodiment provides vertical heat recovery coke oven supporting waste gas waste heat boiler flue gas emission system, include: waste gas waste heat boiler, fan, support body and chimney. Waste gas waste heat boiler includes boiler outer wall and boiler body heat receiving surface, the boiler outer wall includes first side portion and second side portion, the bottom of first side portion is connected with the flue gas export of vertical heat recovery coke oven, the middle part of second side portion is provided with the air outlet flue, the bottom of second side portion is suspendedly arranged, be provided with first pass space in the bottom of second side portion, the boiler body heat receiving surface is arranged in the boiler outer wall; The entrance of fan is connected with the air outlet flue, and the outlet of fan is connected with chimney, and the fan is set up in the support body, so that the fan is set up higher than ground. On the one hand, the fan is set up higher than ground, so that the fan and the air outlet flue of waste gas waste heat boiler middle part are closer, and the length of air outlet flue can be reduced. On the other hand, the fan is not directly set on the ground, and the ground area originally set with the fan can be reduced.
