A combined flue gas waste heat recovery unit

Abstract

This utility model discloses a combined flue gas waste heat recovery device, relating to the field of waste heat recovery technology. It includes a shell and heat exchange tubes, with two heat exchange tubes arranged abutting each other from top to bottom. The heat exchange tubes are disposed inside the shell. An outlet pipe is fixedly installed on one side of the upper end of the shell, and an inlet pipe is fixedly installed on one side of the lower end of the shell. The outer diameter of the inlet pipe matches the inner diameter of the outlet pipe. A medium inlet pipe and a medium outlet pipe are fixedly installed on both sides of the shell. Fixing rings are fixedly installed on both sides of the lower end of the shell, and rotating rods are rotatably installed on both sides of the upper end of the shell. An L-shaped rod is fixedly sleeved on the wall of the rotating rod, and the upper end of the L-shaped rod is engaged with the fixing ring. A limiting mechanism is provided on the outer wall of the shell, below the rotating rod, to restrict the rotation of the rotating rod. This utility model can combine multiple heat exchange tubes, increasing the flue gas waste heat recovery time and ensuring sufficient recovery of flue gas waste heat.
