Problems solved by technology

[0004] Although the temperature of the exhaust gas has dropped after being shaped, the exhaust gas is still higher than the room temperature. The exhaust gas is only filtered through a single stage, and still contains a small amount of oil, smoke, dyes, flying flocs and other sundries. The filtering effect is not ideal, especially When shaping chemical fiber fabrics, more grease is produced, and it is more difficult to completely remove the grease through single-pass filtration. Moreover, most of the exhaust gas enters the atmosphere directly through the exhaust port 3' without filtration and waste heat recovery, and these exhaust gases fall to the periphery of the factory. environment, causing pollution and heating up the environment, and the waste heat of the exhaust gas has not been well recycled

Abstract

The invention provides a waste gas treatment and heat energy recycling device for a heat-setting machine, comprising a baking oven, a hot-air pipe, a draught fan and a high-temperature purifier which are arranged in an oven, wherein, the hot-air pipe is positioned on the upper part of the baking oven and is provided with an air inlet end; the draught fan is provided with an air draft side and an exhaust end; an air channel is formed between the air inlet end of the hot-air pipe and the exhaust end of the draught fan; an air-collecting box is arranged between an air draft end of the draught fan and the high-temperature purifier; a waste gas heat recycling pipe is arranged in the baking oven and above a heat-setting pipe; and the waste gas heat recycling pipe and the high-temperature purifier are connected through an induced waste gas connection tube. The invention ensures that set waste gas can realize centralized recycling and quick conveying through adding the waste gas heat recycling pipe and the induced waste gas connection tube, and has no waste gas exhausted outside the heat-setting machine. The device does not occupy peripheral space of the heat-setting machine, so the device has the advantages of high efficiency and energy conservation, environmental protection and small occupied space of the baking oven.

Description

technical field [0001] The invention relates to a waste gas treatment and heat energy recovery device of a heat setting machine, in particular to a device for processing waste gas generated during heat setting of fabrics and recycling the heat energy of the waste gas, belonging to the field of textile machinery finishing equipment manufacturing. Background technique [0002] During the "Eleventh Five-Year Plan" period, my country's dyeing and finishing industry has experienced unprecedented rapid development, and its share of global production capacity continues to rise. At the same time, the energy consumption and pollution of the dyeing and finishing industry have also become increasingly heavy. The awareness is weak, especially for the treatment of heat setting machine waste gas and the recovery of heat energy. finishing equipment, while the existing heat setting machine waste gas treatment and heat recovery devices such as figure 1 As shown: mainly set the oven 1', the up...
