Description

Technical Field

[0001] This utility model relates to the field of flue gas recovery technology, and in particular to a flue gas recovery device for a heat treatment furnace. Background Technology

[0002] Heat treatment is one of the important processes in mechanical manufacturing. Generally, heat treatment does not change the shape and overall chemical composition of the workpiece, but rather imparts or improves the performance of the workpiece by changing the internal microstructure or the chemical composition of the surface. Heat treatment furnaces are required in the heat treatment process. Heat treatment furnaces can be divided into quenching furnaces, tempering furnaces, annealing furnaces, etc., depending on their purpose. When heat treatment furnaces are in use, a large amount of high-temperature waste gas is generated. Therefore, flue gas recovery devices are needed to recover it. Traditional recovery methods mostly involve directly transferring heat from the flue gas to the water tank via heat pipes to heat the water. However, this method cannot fully recover and utilize the waste heat from the flue gas, resulting in some heat loss and waste when the flue gas is discharged. Therefore, it has the drawback of not being able to fully recover and utilize the heat, and thus cannot meet the needs of customers.

[0003] Therefore, those skilled in the art have provided a flue gas recovery device for a heat treatment furnace to solve the problems mentioned in the background art. Utility Model Content

A serpentine heat-conducting pipe 2 is fixedly installed in the inner cavity of the water tank 1 via a bracket. A processing box 3 is fixedly connected to the bottom of the water tank 1. An insulation box 4 is embedded in the right side of the processing box 3. A gas storage pipe 5 is fixedly connected between the left and right sides of the inner cavity of the processing box 3 and below the insulation box 4. Through holes 6 are evenly distributed on the outer surface of the gas storage pipe 5. A conduit 7 is connected to the left side of the top of the gas storage pipe 5. The top of the conduit 7 extends into the inner cavity of the water tank 1 and communicates with the serpentine heat-conducting pipe 2. An exhaust pipe 8 is connected to the top of the left side of the water tank 1. A filter cartridge 9 is connected to the top of the exhaust pipe 8. Activated carbon 10 is placed in the inner cavity of the filter cartridge 9. The top of the filter cartridge 9 is threaded with a cover 11, and a filter screen 12 is embedded in the top of the cover 11. Support components 13 are provided at the four corners of the bottom of the treatment box 3. The top of the left side of the serpentine heat pipe 2 is connected to an air inlet pipe 14, one end of which extends to the outside of the water tank 1. The bottom of the right side of the water tank 1 is connected to an outlet pipe 15, and a valve is provided on the outer surface of the outlet pipe 15. The right side of the top of the water tank 1 is connected to an inlet pipe 16, and a pipe cover is threaded to the top of the inlet pipe 16. The left side of the bottom of the treatment box 3 is connected to a drain pipe 17, and a sealing cap is threaded to one end of the drain pipe 17. A guide plate is fixedly connected to the left side of the bottom of the inner cavity of the treatment box 3.

[0024] In this embodiment: By setting up a water tank 1 and a serpentine heat-conducting pipe 2, the water inside the water tank 1 can be easily heated by conduction. By setting up a processing box 3, an insulation box 4, a gas storage pipe 5, and a through hole 6, the flue gas can be filtered by water. At the same time, the heated water conducts heat to the insulation box 4, which can keep the items warm. By setting up a conduit 7, an exhaust pipe 8, a filter cartridge 9, activated carbon 10, a cylinder cover 11, and a filter screen 12, the flue gas can be subjected to secondary adsorption and filtration. By setting up the above structure, it is easy to fully recycle and reuse, thereby meeting the customer's usage needs and avoiding heat loss and waste.

[0025] Example 2: Reference Figure 1 , Figure 2 and Figure 4 The support assembly 13 includes a stud 131, a support cylinder 132 is threadedly connected to the outer surface of the stud 131, a support plate 133 is fixedly connected to the bottom of the support cylinder 132, and the top of the stud 131 is fixedly connected to the connection of the processing box 3. The support plate 133 is circular.

[0026] In this embodiment: the present invention can support the device by setting studs 131, support cylinders 132 and support discs 133, and at the same time adjust its horizontal state.

[0027] The implementation principle of this utility model is as follows: When in use, the staff moves the device to the designated recycling position. Then, the staff rotates the moving support cylinder 132 in sequence, so that the support cylinder 132 drives the support plate 133 to rotate and move downward on the outer surface of the stud 131 to contact the ground. Thus, the four support plates 133 and the support cylinder 132 work together to support the device and adjust its horizontal state. Next, the staff connects the exhaust pipe of the external heat treatment furnace through the air inlet pipe 14, allowing the pressurized flue gas to enter the serpentine heat conduction pipe 2 through the air inlet pipe 14. The heat in the flue gas is then transferred to the serpentine heat conduction pipe 2, which in turn heats the water inside the water tank 1. Simultaneously, the flue gas enters the inner cavity of the gas storage pipe 5 through the conduit 7. The flue gas then exits through the through hole 6, allowing it to dissolve, adsorb, and filter with the water inside the treatment box 3. At the same time, the heat in the flue gas is transferred to the water, heating the insulation box 4, which then insulates the items, thus achieving full recovery and utilization of the waste heat from the flue gas. Next, the flue gas, after water adsorption and filtration, enters the inner cavity of the filter cartridge 9 through the exhaust pipe 8, where the activated carbon 10 inside the filter cartridge 9 performs secondary adsorption and filtration, achieving the recovery and treatment of the flue gas. This device is simple to operate, facilitates full recovery and utilization, meets customer needs, and avoids heat loss and waste.

[0028] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
