Waste heat recycling device of textile cloth dryer

Abstract

The invention discloses a waste heat recycling device of a textile cloth dryer. The waste heat recycling device comprises a cloth pre-dryer and a waste gas pretreatment bin, wherein one end of the waste gas pretreatment bin is connected to the top of a cloth dryer through a ventilating pipe; the other end of the waste gas pretreatment bin is connected to the bottom of the cloth pre-dryer through air-blasting equipment; humid and hot waste gas exhausted by the cloth dryer is exhausted into the waste gas pretreatment bin through air inducing equipment on the top of the cloth dryer and the ventilating pipe; and after being subjected to humidity-removal and impurity-removal treatment of the waste gas pretreatment bin, the humid and hot waste gas is blast into the cloth pre-dryer through the air-blasting equipment for pre-drying cloth. According to the waste heat recycling device for the textile cloth dryer provided by the invention, heat energy in exhausted waste gas of the textile dryer is sufficiently utilized and textile cloth is pre-dried, so that waste heat is effectively recycled, and therefore, the waste heat recycling device is energy-saving and environmentally-friendly.

Description

technical field [0001] The invention relates to the technical field of heat energy recovery and utilization, in particular to a waste heat recovery and utilization device for fabrics dried by a textile fabric 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 e...
