Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Example 1

The utility model provides a flue gas waste heat exchanger, refer to fig. 1 and fig. 2, including base 1, shell 2, apron 3, guide rail 4, heat exchange tube 5 and dead lever 6, base 1 is equipped with two, distribute about being, be connected with shell 2 between two 1 tops of base, the right side bolt of shell 2 has apron 3, the inner wall interval of shell 2 is connected with four

guide rails

4, 2 inside heat exchange tubes 5 that are equipped with of shell, 5 outer wall intervals of heat exchange tubes have four dead levers 6, dead lever 6 slides on guide rail 4, can drive the stable removal of heat exchange tube 5, make things convenient for people to carry out dismouting and maintenance to heat exchange tube 5.

Let in the heat exchange tube 5 with the flue gas, can utilize the heat transfer of heat exchange tube 5 in to the flue gas, be used for heating other materials, when needs overhaul heat exchange tube 5, at first dismantle apron 3 gets off, then take out heat exchange tube 5 to the right pulling, drive dead lever 6 and turn right the motion, guide rail 4 plays the guide effect, make things convenient for taking out of heat exchange tube 5, and stability is better, then can overhaul work, overhaul the completion back, need aim at dead lever 6 guide rail 4 and push left, drive heat exchange tube 5 and turn left the motion, make heat exchange tube 5 return to the normal position, it can to install the normal position again at last with apron 3.
