Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a heat recovery device for textile dyeing and finishing equipment. Background Art

[0002] Textile dyeing and finishing equipment is one of the main energy-consuming equipment in the textile dyeing and finishing industry. Heat setting equipment is a device that uses hot air to dry, finish and set fabrics. Because the setting equipment uses high temperature to operate, and different fabrics have different substances left on textile fabrics, such as chemical fiber fabrics often have grease left on them, which will be vaporized and attached to the exhaust gas of the setting equipment after high-temperature steam treatment. In addition, cotton fiber fabrics have paraffin left on them, which will also be vaporized and attached to the exhaust gas of the setting equipment after high-temperature steam treatment. If the temperature and humidity of the discharged exhaust gas are greatly different from the temperature and humidity of the air in the external environment, steam tail flow will be generated at the final outlet of the exhaust gas, affecting air visibility, causing great environmental pollution and affecting environmental protection. Therefore, exhaust gas treatment is required. At present, the common high-temperature exhaust gas treatment method is to collect the high-temperature exhaust gas discharged from the drying room of the setting equipment through the exhaust branch pipe and the main pipe of the drying room and concentrate it at the end of the system for heat recovery and filtering of harmful substances in the exhaust gas.

[0003] At present, the common exhaust gas treatment device of the setting equipment is usually an air-to-air heat exchange structure, which makes the high-temperature hot exhaust gas flow inside or outside the heat exchange tube, and makes the low-temperature gas that needs heat exchange flow on the other side of the patient tube, so as to realize the recovery and utilization of the heat in the high-temperature exhaust gas. However, there are impurities such as dust and oil wax in the exhaust gas of the setting equipment. After the heat exchange tube is used for a long time, the impurities such as dust and oil wax will adhere to the heat exchange tube, which will affect the heat exchange effect and reduce the heat exchange efficiency. In addition, in order to avoid the impurities in the exhaust gas from being directly discharged into the air, a filter component is usually set during heat recovery to filter the impurities in the exhaust gas. However, due to the high content of impurities such as dust and oil wax in the exhaust gas, the filter component is very easy to be blocked, and the filter component needs to be cleaned or replaced frequently, resulting in low exhaust gas treatment efficiency. For this reason, we propose a heat recovery device for textile dyeing and finishing equipment to solve the above problems. Utility Model Content
