Problems solved by technology

[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

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the drawings. Such as figure 1 The illustrated textile dryer waste heat utilization device includes a fabric pre-dryer 3 and a heat exchange device 1. The heat exchange device 1 is placed on the top of the fabric dryer 2 and includes a hot and humid exhaust gas channel 11 and a fresh and dry air channel 12 , Respectively used to pump the hot and humid exhaust gas and dry cold air discharged from the cloth dryer 2, a heat exchange device 13 is arranged between the hot and humid exhaust gas passage 11 and the fresh dry air passage 12, and the dry and cold air circulating in the fresh dry air passage 12 The air absorbs the heat of the hot and humid exhaust gas flowing through the hot and humid exhaust gas channel 11 by using the principle of heat exchange, and is discharged into the fabric pre-drying machine 3 through the ventilation pipe 14 to pre-dry the fabric 31.

Abstract

A waste heat utilization device for a textile dryer, including a fabric pre-dryer and a heat exchange device, the heat exchange device is placed on the top of the fabric dryer, and includes a damp and hot exhaust gas channel and a fresh dry air channel, which are respectively used for pumping into the fabric for drying The hot and humid exhaust gas and dry cold air discharged from the machine, a heat exchange device is arranged between the hot and humid exhaust gas channel and the fresh and dry air channel, and the dry cold air circulating in the fresh and dry air channel uses the principle of heat exchange to absorb the wet and hot exhaust gas flowing through the hot and humid exhaust gas channel. The heat is discharged into the fabric pre-drying machine through the ventilation pipe to pre-dry the fabric. The waste heat reuse device of the dryer provided by the invention fully utilizes the heat energy in the exhaust gas discharged from the textile dryer, and pre-dries the textile fabric, thereby realizing the 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 waste heat reuse device after a textile cloth dryer has dried cloth. Background technique [0002] In the textile industry, the dryer is mainly used for the drying and fixing 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 heated After drying, the moisture evaporates to the inner space of the dryer, and is discharged to the outside of the dryer along with the hot air flow or the exhaust air flow. The exhaust gas temperature is relatively high, but because the exhaust gas contains a large amount of impurities such as moisture and lint, It is not easy to use it for secondary use. Therefore, under normal circumstances, the waste heat airflow is directly discharged into the atmosphere. The lost heat causes a large waste of energy. Because the heat e...
