Technical Field

[0001] This application relates to the field of textile dryer technology, and in particular to a waste heat recovery pipeline system for textile dryers. Background Technology

[0002] Textile dryers play a vital role in the textile industry. Their main functions include drying, sterilization, and dehumidification. By heating air, textile dryers rapidly dry wet textiles, removing moisture. This not only shortens drying time but also improves production efficiency. In the high-temperature environment, dryers effectively kill bacteria and mites on textiles, ensuring product hygiene and safety. Through hot air circulation and mechanical movement, dryers quickly evaporate moisture from textiles, preventing mold and bacterial growth. Textile dryers are widely used in the processing of various textiles, including cotton, linen, silk, wool and other materials. Dryers are indispensable equipment in all production stages of textile factories, especially after dyeing, printing and finishing processes. Dryers can ensure that textiles reach the standard degree of dryness, thereby ensuring product quality.

A portion of the waste heat gas can be filtered again through the filter box 2 and then transported into the textile dryer body 1 for reuse, realizing the recycling of waste heat. A portion of the waste heat gas is discharged through the exhaust port to prevent excessive waste heat gas pressure from burdening the inside of the textile dryer body 1, thereby improving the practicality of the device.

[0019] Reference Figure 1-4 The riser pipe 31 is fixedly connected to the textile dryer body 1, and the lower drain pipe 33 is fixedly connected to the filter box 2. The riser pipe 31 and the lower drain pipe 33 are connected by a conveying pipe 32 through a flange assembly 35. The waste heat gas generated by the textile dryer body 1 enters the conveying pipe 32 through the riser pipe 31, and is conveyed to the lower drain pipe 33 through the conveying pipe 32. The lower drain pipe 33 discharges the waste heat gas into the filter box 2 for filtration and reuse, thereby improving the practicality of the device.

[0020] Reference Figure 1-4 The flange assembly 35 includes a first flange 351 and a second flange 352, which are detachably connected by bolts. By setting the flange assembly 35, it is convenient to connect and disconnect the pipes. The sealing performance between the first flange 351 and the second flange 352 is strong, which can prevent gas leakage and thus improve the practicality of the device.

[0021] Reference Figure 1-4A discharge pipe 34 is provided on the lower discharge pipe 33, and a control valve 36 is provided on the lower discharge pipe 33 and below the discharge pipe 34. By closing the control valve 36, the channel between the lower discharge pipe 33 and the filter box 2 is closed, and then the gas in the textile dryer body 1 is discharged into the discharge pipe 34 through the riser pipe 31 and the conveying pipe 32. This can completely discharge the waste heat gas in the textile dryer body 1, thereby improving the practicality of the device.

[0022] Reference Figure 1-4 The pipe wall structure of the riser pipe 31, the conveying pipe 32, and the lower pipe 33 includes an outer pipe wall 301, an insulation layer 302, a heat extraction pipe assembly 303, and a ceramic layer 304.

With the cooperation of the heat extraction pipe assembly 303 and the insulation layer 302, the waste heat can be effectively recovered, thereby improving the practicality of the device.

By developing a new ceramic material adapted to the working conditions of the waste heat recovery pipeline system 3, the ceramic material fully covers the metal surface of the heat extraction pipe assembly 303 in the waste heat recovery pipeline system 3, avoiding direct contact between the waste heat gas and the metal of the heat extraction pipe assembly 303 in the waste heat recovery pipeline system 3, eliminating corrosion conditions. Moreover, this ceramic material has the characteristics of water hammer resistance, high pressure resistance, and high temperature resistance, thereby improving the practicality of the device.

[0024] Working principle: Gas enters the textile dryer body 1 through the filter box 2, is heated by the textile dryer body 1, and is used for drying. The waste heat gas generated by the textile dryer body 1 enters the conveying pipe 32 through the riser pipe 31, and is conveyed to the lower discharge pipe 33 through the conveying pipe 32. The lower discharge pipe 33 discharges the waste heat gas into the filter box 2. A portion of the waste heat gas can be filtered again through the filter box 2 and then conveyed back into the textile dryer body 1 for use, realizing the recycling of waste heat. A portion of the waste heat gas is discharged through the exhaust port to prevent the waste heat gas pressure from being too high and putting a burden on the inside of the textile dryer body 1. When it is necessary to discharge and purify the gas in the textile dryer body 1, the control valve 36 can be closed to close the channel between the lower discharge pipe 33 and the filter box 2. Then the gas in the textile dryer body 1 is discharged into the exhaust pipe 34 through the riser pipe 31 and the conveying pipe 32, which can realize the complete discharge of waste heat gas in the textile dryer body 1.

[0025] After the waste heat gas enters the inner channel of the waste heat recovery pipeline system 3, the ceramic layer 304 has a strong heat absorption performance. With the cooperation of the heat collection tube assembly 303 and the insulation layer 302, the waste heat can be effectively recovered. By developing a new ceramic material that is adapted to the working conditions of the waste heat recovery pipeline system 3, the ceramic material fully covers the metal surface of the heat collection tube assembly 303 in the waste heat recovery pipeline system 3, avoiding direct contact between the waste heat gas and the metal of the heat collection tube assembly 303 in the waste heat recovery pipeline system 3, eliminating corrosion conditions. Moreover, this ceramic material has the characteristics of water hammer resistance, high pressure resistance, and high temperature resistance.
