Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to a waste gas recovery device for paper tube drying equipment. Background Technology
[0002] Paper tubes, as tubular objects made from paper, are widely used in packaging, transportation, and many other fields. During the manufacturing process, drying is typically required to promote rapid glue coagulation, enabling the paper tube to be quickly formed and maintain structural stability during subsequent transportation. Drying equipment plays a crucial role in this process; it provides the necessary heat to accelerate the evaporation of moisture inside the paper tube, thereby achieving rapid drying.
[0003] However, the use of drying equipment generates a large amount of exhaust gas containing heat. This exhaust gas is often directly emitted into the atmosphere, bringing many adverse effects. First, exhaust gas emissions have a thermal impact on the environment. The heat in the exhaust gas is released directly into the air without treatment, which can lead to a rise in local temperature, affect the distribution of ambient temperature, and may even exacerbate the urban heat island effect. Second, exhaust gas emissions also cause a large waste of thermal energy, making it impossible to utilize the heat in the exhaust gas.
[0004] Therefore, it is necessary to provide a waste gas recovery device for paper tube drying equipment to solve the above-mentioned technical problems. Utility Model Content

The exhaust gas recovery device for paper tube drying equipment includes: a shell 1, with a discharge pipe 13 fixedly installed on one side of the shell 1, a fan 2 fixedly installed on one side of the shell 1, and an exhaust pipe 3 fixedly installed on the exhaust end of the fan 2 for sucking up the exhaust gas generated by the paper tube drying equipment; an exhaust pipe 4 fixedly installed on the exhaust end of the fan 2, one end of the exhaust pipe 4 extending into the interior of the shell 1, with a first box 5 fixedly installed on the exhaust pipe 4, and multiple exhaust holes opened at the bottom of the first box 5; a water tank 6 fixedly installed at the bottom of the shell 1 for storing water; and a water tank 6 fixedly installed at the bottom of the shell 1. The device includes a through pipe 9, the bottom end of which extends into the interior of the water tank 6; a spray mechanism installed on the housing 1 for recovering heat from the exhaust gas; and a power generation mechanism mounted on the housing 1 and the discharge pipe 13 for generating electricity.

[0029] It is worth noting that the circuits, electronic components, and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.
[0030] The working principle of the exhaust gas recovery device for the paper tube drying equipment provided by this utility model is as follows:
[0031] During operation, fan 2 is started. Fan 2 transports the exhaust gas generated during the operation of the paper tube drying equipment to the first chamber 5 through the suction pipe 3 and the exhaust pipe 4. The exhaust gas is then discharged from multiple exhaust holes at the bottom of the first chamber 5. During this process, water pump 7 is also started. Water pump 7 transports water from the water tank 6 to the connecting pipe 10 through the water suction pipe 8. The connecting pipe 10 then transports the water to the second chamber 11, where it is sprayed out from multiple atomizing nozzles 12. The sprayed water is atomized into fine water droplets, forming a water mist. This water mist comes into full contact with the exhaust gas, and the heat in the exhaust gas is absorbed by the water mist, thereby achieving heat dissipation. The water, having absorbed heat, flows from pipe 9 into water tank 6. Because the water in tank 6 can be heated by the exhaust gas recovery, its temperature increases with usage time. This heated water can be used in situations requiring hot water, effectively utilizing the heat energy from the exhaust gas recovery. To drain water from tank 6, simply open the valve on the drain pipe. To replenish water to tank 6, first close the valve on the drain pipe, then open the valve on the inlet pipe, allowing water to be added to tank 6 via the inlet pipe. This process is quite convenient.
[0032] After being sprayed, the exhaust gas temperature is greatly reduced. It then continues to flow through the channel inside the housing 1. At this time, the exhaust gas encounters the inclined baffle 24, which can block the exhaust gas to a certain extent, increasing the contact time between the exhaust gas and the water mist, which is beneficial to improving the heat recovery efficiency. Then, the cooled exhaust gas is discharged from the exhaust pipe 13. The temperature of the discharged exhaust gas is low and will not have a thermal impact on the environment. During the process of the exhaust gas being discharged from the exhaust pipe 13, multiple blades 19 inside the exhaust pipe 13 will drive the rotating shaft 18 to rotate on the bracket 17. The rotating shaft 18 will drive the first sprocket 20 to rotate. The first sprocket 20 will drive the second sprocket 21 to rotate through the chain 22. The second sprocket 21 will drive the drive shaft of the generator 16 to rotate, thereby driving the generator 16 to generate electricity. The generated electricity can be stored in the battery 15 inside the housing 14 for the use of the device, thereby reducing the power cost of the device and making it more environmentally friendly.
[0033] Compared with related technologies, the exhaust gas recovery device for paper tube drying equipment provided by this utility model has the following beneficial effects:
[0034] This utility model provides a waste gas recovery device for a paper tube drying equipment. Through the coordinated use of a fan 2, an extraction pipe 3, an exhaust pipe 4, a first housing 5, and multiple exhaust holes, the waste gas generated during the operation of the paper tube drying equipment can be transported into the housing 1. The spray mechanism utilizes water in a water tank 6 to absorb the heat of the waste gas entering the housing 1. This not only reduces the exhaust temperature of the recovered waste gas, preventing thermal impact on the environment, but also heats the water in the water tank 6. This heated water can be used in situations requiring hot water, effectively utilizing the heat energy from the recovered waste gas. The exhaust pipe 13 discharges the cooled waste gas. During the discharge process, a power generation mechanism can use the discharged waste gas to generate electricity, which can be used by the device or supplied to other equipment, effectively reducing the device's electricity costs and making it more environmentally friendly.
