Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, and in particular to a fin-tube heat exchanger for recovering waste heat from a high-temperature cloth setting machine. Background Art

[0002] my country is a major textile producer. Exhaust emissions from stentering machines in the printing and dyeing industry waste significant energy and pollute the environment, making waste heat recovery and purification from these machines crucial. The printing and dyeing industry consumes approximately 1.5 tons of coal to process one ton of knitted fabric, of which stentering machines account for approximately 40%. However, the heat energy consumed by the fabric during operation only accounts for 29%, while the machine itself consumes 10%, while the heat emitted by exhaust gases accounts for 61%. The exhaust gas emitted from stentering machines processing chemical fiber products has an emission temperature of 160-170°C. The waste heat recovery process within these machines contains a significant amount of heat energy. Failure to recover this heat would result in energy loss and waste, increasing production costs for the company.

[0003] The current fin-tube heat exchanger used for waste heat recovery in high-temperature fabric setting machines achieves the purpose of enhancing heat transfer by adding fins to ordinary base tubes. The base tubes can be made of steel tubes, stainless steel tubes, copper tubes, etc., and the fins can also be made of steel strips, stainless steel strips, copper strips, aluminum strips, etc. Because the fins are very thin, protective measures need to be taken to ensure that they are not damaged by impact. However, due to the relatively comprehensive covering, the heat exchange effect of the heat exchanger is poor, and each maintenance requires the equipment to be dismantled to check for damage, which is time-consuming and labor-intensive.

By means of a first motor driving the gear to rotate, the gear ring can drive the rotating tube to rotate, so that it can be observed through the glass whether there is any place inside the heat exchanger that needs maintenance. If maintenance is required, the baffle can be pushed by the handle to repair the heat exchanger.

[0025] Example

[0026] See also Figure 1-4The utility model provides a fin-tube heat exchanger for waste heat recovery of a high-temperature setting machine for fabrics, comprising an inspection structure 100 and a heat dissipation structure 200 arranged on one side of the inspection structure 100. The inspection structure 100 comprises a protective tube 110 and an inspection component 120. The inspection component 120 comprises a rotating tube 121. The rotating tube 121 plays a role in protecting the heat exchange component 220. The rotating tube 121 is rotatably connected to one side of the protective tube 110. A limiting ring 122 is fixed on one side of the rotating tube 121. The limiting ring 122 prevents the rotating tube 121 from sliding inside the rotating tube 121 due to the coaxiality of the center of the rotating tube 121 and the center of the protective tube 110. A baffle 123 is connected, and glass 124 is fixed inside the baffle 123. Through the glass 124, it is possible to check whether the heat exchange component 220 needs maintenance. A handle 125 is fixed on one side of the baffle 123, and the handle 125 facilitates pushing the baffle 123 to slide. A strong magnet 126 is fixed on one side of the baffle 123, and the strong magnet 126 prevents the baffle 123 from sliding after it is opened. A strong magnet 2 127 is fixed on one side of the baffle 123, and the strong magnet 2 127 prevents the baffle 123 from sliding after it is closed. A gear ring 128 is fixed on one side of the rotating tube 121, and the gear ring 128 is engaged with the gear 114.

[0027] See also Figure 1-3 A connecting strip 111 is fixed inside the protective tube 110, and the connecting strip 111 serves to strengthen the rigid connection. A docking tube 112 is fixed on one side of the connecting strip 111, and the docking tube 112 serves to support the rotating tube 121. A motor 113 is fixed on one side of the docking tube 112, and a gear 114 is fixed on the output shaft end of the motor 113. The gear 114 is engaged with the gear ring 128. A support strip 115 is fixed inside the docking tube 112, and the support strip 115 ensures that the blown wind can be discharged from the docking tube 112 while also fixing the heat exchange component 220. A support leg 116 is fixed on one side of the docking tube 112.

[0028] See also Figure 1-2 and Figure 4The heat dissipation structure 200 includes a blowing member 210 and a heat exchange member 220. The blowing member 210 is fixed to one side of the protective tube 110, and the heat exchange member 220 is fixed inside the protective tube 110. The blowing member 210 includes a wind frame 211. The wind frame 211 plays a supporting role. The wind frame 211 is fixed to one side of the protective tube 110. A protective net 212 is fixed on the top of the wind frame 211. The protective net 212 prevents larger foreign matter from entering the wind frame 211. A motor 213 is fixed on the top of the protective net 212. A fan blade 214 is fixed to the output shaft end of the motor 213. The fan blade 214 can be driven by rotation. To promote air flow, the heat exchange element 220 includes a base tube 221, which is fixed inside the protective tube 110. A heat dissipation fin 222 is fixed on one side of the base tube 221. The heat dissipation fin 222 can guide the heat on the base tube 221 out, thereby achieving faster heat dissipation through large-area contact with the air. A heat dissipation hole 223 is opened on one side of the heat dissipation fin 222. A spiral bar 224 is fixed inside the base tube 221. The spiral bar 224 can make the liquid flowing in the base tube 221 spiral forward, so that the liquid stays in the base tube 221 for a longer time, thereby achieving long-term heat dissipation.

[0029] Specifically, the working principle of the fin tube heat exchanger for waste heat recovery of a high temperature setting machine for fabrics is as follows: when in use, when it is necessary to check the heat exchanger, the motor 113 can be started, so that the motor 113 drives the gear 114 to rotate, so that the gear ring 128 can drive the rotating tube 121 to rotate. When the rotating tube 121 rotates, the heat exchanger in the rotating tube 121 can be checked through the glass 124. If it is found that there is a place that needs maintenance, the motor 113 is stopped, and the baffle 12 is pushed by the handle 125. 3 slides in the rotating tube 121, and the baffle 123 is prevented from sliding down by the strong magnet 126. Then, the heat exchanger can be repaired. The motor 213 drives the fan blades 214 to rotate, so that the outside air can enter the wind frame 211 through the protective net 212, and then enter the protective tube 110, the rotating tube 121 and the docking tube 112, so as to cool the heat dissipation fins 222, thereby preventing the problem of poor heat dissipation effect of the heat exchanger due to the tight covering of the equipment.

[0030] It should be noted that the specific model specifications of motor 113 and motor 2 213 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0031] The power supply and principle of the motor 1 113 and the motor 2 213 are clear to those skilled in the art and will not be described in detail here.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
