Dryer waste heat reutilization device

Abstract

A dryer waste heat recycling device, comprising a fabric pre-dryer and a dehumidification and impurity removal bin, one end of the dehumidification and impurity removal bin is connected to the top of the cloth dryer through a ventilation pipe, and the other end is connected to the top of the cloth dryer through a plurality of blowing equipment. The bottom of the fabric pre-dryer is connected, and the hot and humid exhaust gas discharged from the fabric dryer is discharged into the dehumidification and impurity removal bin through the air induction equipment and the ventilation pipe on the top of the cloth dryer. The moisture and impurities in the hot and humid exhaust gas will settle under the action of its own weight, and the hot exhaust gas after dehumidification and impurity removal will be blown into the fabric pre-dryer through the blower equipment to pre-dry the fabric. The waste heat recycling device of the dryer provided by the invention fully utilizes the heat energy in the waste gas discharged from the textile dryer, and pre-dries the textile cloth, thereby realizing effective recovery and utilization of waste heat, energy saving and environmental protection.

Description

technical field [0001] The invention relates to the technical field of heat energy recovery and utilization, in particular to a device for reusing waste heat after drying cloth by a textile cloth dryer. Background technique [0002] In the textile industry, the dryer is mainly used for drying and fixing the color of textile fabrics. The heating and drying methods mainly include hot air heating and electric heating. During the working process, the fabric in the dryer is After drying, the water evaporates to the inner space of the dryer, and is discharged out of the dryer with the hot air flow or the dehumidified air flow. The temperature of the discharged exhaust gas is relatively high, but because the exhaust gas is mixed with a large amount of impurities such as water vapor and fluff, It is not easy to reuse it, so usually the waste hot air will be directly discharged into the atmosphere, and the lost heat will cause a lot of waste of energy. Because the heat energy has not...

[0002] In the textile industry, the dryer is mainly used for drying and fixing the color of textile fabrics. The heating and drying methods mainly include hot air heating and electric heating. During the working process, the fabric in the dryer is After drying, the water evaporates to the inner space of the dryer, and is discharged out of the dryer with the hot air flow or the dehumidified air flow. The temperature of the discharged exhaust gas is relatively high, but because the exhaust gas is mixed with a large amount of impurities such as water vapor and fluff, It is not easy to reuse it, so usually the waste hot air will be directly discharged into the atmosphere, and the lost heat will cause a lot of waste of energy. Because the heat energy has not been effectively used, the textile dryer will It consumes a lot of energy, and the high-temperature waste hot air will bring serious thermal radiation pollution, which will have a great impact on the surrounding environment
