Technical Field

[0001] The utility model relates to the technical field of energy conservation, and particularly relates to a waste heat recovery device for an incinerator. Background Art

[0002] The flue gas discharged after incineration by an RTO furnace is often around 60°C. If directly discharged, it will cause heat waste. Therefore, a waste heat recovery device is often used to recycle the heat in the flue gas discharged from the incinerator. Common waste heat recovery devices often use heat exchangers or heat exchange plates to absorb energy and heat the water in the water pipes to achieve the purpose of heat recovery. Common heat exchangers use a whole end plate to fix the entire pipeline, which is not only inconvenient for installation and disassembly, but also has relatively high production and transportation costs due to the long length of the water pipes.

A plurality of semi-circular clamping grooves are formed on the upper side of the lower clamping plate; the water storage pipe is clamped into the semi-circular clamping grooves of the lower clamping plate; semi-circular clamping grooves corresponding to the lower clamping plate are formed on the lower side of the upper clamping plate, which is pressed on the water storage pipe and corresponds to the lower clamping plate one by one. A plurality of upper clamping plate screws are installed on the upper side surface and screwed into the lower clamping plate; the water pipe connecting pipe connects the ends of a plurality of water storage pipes and is equipped with a hose to connect to the water pipe.

[0004] As a preferred technical solution of the utility model, the front and rear end faces of the lower clamping plate are flush with the mounting column.
