Flue gas flow guide structure of waste heat boiler

Abstract

The invention provides a waste heat boiler flue gas diversion structure, and belongs to the technical field of gas turbine waste heat boiler flue gas treatment equipment. Comprising a smoke inlet box and a smoke outlet box, the output end of the smoke inlet box communicates with a flow guide box, the output end of the flow guide box communicates with the smoke outlet box, the exterior of the top of the flow guide box communicates with a circular box, an access cover is installed on one side of the circular box, a containing box is fixedly connected to the bottom of the flow guide box, and an access door is installed on one side of the containing box; a flow guide assembly used for filtering waste gas in the flue gas is arranged in the flow guide box and comprises a downstream plate, a partition plate, a first filter plate, a second filter plate and a second flow guide plate. By arranging the flow guide assembly, flue gas can be guided into the flow guide box, then the filter plate is promoted to carry out waste gas treatment on the flue gas, in this way, loss of the heat exchanger caused by particulate matter in the waste gas can be avoided, meanwhile, later flue gas treatment is facilitated, and therefore the utilization rate of the flue gas is increased.
