Inside the housing (101), there is a machine compartment (201) for housing the compressor body (102) and the electric motor (103), and a B compartment (204) for accommodating a pipe (108) connecting the compressor body (102) and the container (105). The compressor body (102) includes a housing (105) containing a chamber A (203), a partition wall A (202) separating the mechanical chamber (201) from chamber A (203) and chamber B (204), and a partition wall B (205) dividing the mechanical chamber (201) into chamber A (203) and chamber B (204). Chamber A (203) has an air inlet (206) for external gas, and partition wall A (202) has an air vent A (301) as a hole connecting the mechanical chamber (201) and chamber A (203). The suction port (109) of the compressor body (102) is located nearby.

This utility model discloses a waste heat recovery device for flue gas from a heat-insulating furnace, comprising a furnace body, a heating chamber located at the upper end of the furnace body, a combustion chamber located at the lower end of the heating chamber, a flue gas outlet located at the upper end of the furnace body, and a connecting pipe located at the upper end of the flue gas outlet. A first heat exchange mechanism for exchanging heat from the flue gas is located inside the connecting pipe. The first heat exchange mechanism includes a fixed plate, a diverter pipe, an inlet pipe, and an outlet pipe. Fixed plates are fixedly installed on both sides inside the connecting pipe, and a plurality of diverter pipes are evenly fixed between the fixed plates. This utility model improves the flue gas filtration and treatment device emitted from the heat-insulating furnace by using diverter pipes to first divert the flue gas, thereby significantly increasing the heat exchange area of ​​the hot flue gas. Compared to devices that only have a heat exchange chamber on the outside of the flue gas outlet pipe, this device can achieve better heat exchange.
