Description

Technical Field

[0001] The utility model relates to the technical field of heat energy recovery equipment, in particular to a multi-stage high-efficiency heat energy recovery equipment for a setting machine. Background Art

[0002] The setting machine is a machine used for industrial manufacturing and is mainly used for weaving setting. Generally, the setting machine uses heat transfer oil (or steam) to heat the air in the setting machine, and then heats the fabric. When the fabric reaches a certain temperature and maintains it for a certain period of time, the fabric structure changes and the setting purpose is achieved. Due to process requirements, the exhaust gas in the setting machine that is high in humidity and mixed with impurities such as cloth wool must be discharged, otherwise it will have an adverse effect on the weaving setting effect. However, a large amount of high-temperature exhaust gas (generally above 150°C) is discharged, and the setting machine needs to reheat the air in the furnace, so a large amount of heat energy is wasted. It is necessary to use heat recovery equipment to recycle the high-temperature exhaust gas generated by the setting machine. For example, Chinese patent CN212000235U discloses a heat recovery device for a setting machine, including a setting machine chassis, wherein the setting machine chassis is provided with electric heating plates distributed on both sides of the cloth, the electric heating plates are connected to a receiving cavity with an opening on the side away from the cloth, the electric heating plates are located at the opening position of the receiving cavity, an insulating layer is provided on the inner wall of the receiving cavity, and an air inlet pipe and an air outlet pipe are respectively provided in the receiving cavity, and the air inlet pipes and air outlet pipes of the plurality of receiving cavities are respectively connected and extend to the outside of the setting machine chassis.

[0003] When performing heat recovery operation, the air needs to be preheated by a preheating device, and then the air in the accommodating cavity is heated by the electric heating plate. Therefore, the above structure needs to use multiple sets of power-on mechanisms to first recover the air in the device for heating before the heat energy of the stenter can be recovered. In this way, the heat energy generated by the waste heat of the exhaust gas of the stenter cannot be completely recovered by using electrical supplementary heating, which will increase the cost of heat recovery of the stenter.
