Exhaust heat recovery device of textile printing and dyeing forming machine

Abstract

The invention discloses an exhaust heat recovery device of a textile printing and dyeing forming machine. The device comprises a recovery pool, wherein a gas-washing heat-conducting liquid is arranged in the recovery pool, a waste gas inlet is arranged at the bottom of the recovery pool, a waste gas outlet is arranged at the top of the recovery pool, a coil is arranged in the recovery pool, one end of the coil extends out of the recovery pool to form a water inlet, the other end of the coil extends out of the recovery pool to form a water outlet, the waste gas inlet is connected to a gas inlet pipeline and the waste gas outlet is connected to a gas outlet pipeline. By the aid of the device, the waste gas can be subjected heat recovery further, harmful substances in waste gas can be cleaned, the heat recovery can be improved, and the exhausted waste gas meet environment protection requirements.

Description

technical field [0001] The invention relates to the field of placed printing and dyeing, in particular to a device for recovering waste gas waste heat of a textile printing and dyeing setting machine. Background technique [0002] In the textile industry, the printing and dyeing setting machine is the main processing equipment and one of the energy-consuming equipment. It is a device that dries and finishes the fabric with heated air to set it. Generally, the hot air temperature required by the setting machine is about 200°C, and the exhaust gas discharge temperature of the setting machine is also about 170°C, which contains rich heat energy. If the heat energy is not recovered, it will cause significant energy loss and waste, resulting in the production cost of the enterprise. increase, and the current heat recovery measures are to directly heat the fresh air to 130°C again. This kind of heating generally uses heat pipes for heat transfer, and then sends it to the setting m...

Generally, the hot air temperature required by the setting machine is about 200°C, and the exhaust gas discharge temperature of the setting machine is also about 170°C, which contains rich heat energy. If the heat energy is not recovered, it will cause significant energy loss and waste, resulting in the production cost of the enterprise. increase, and the current heat recovery measures are to directly heat the fresh air to 130°C again. This kind of heating generally uses heat pipes for heat transfer, and then sends it to the setting machine for recycling. At the same time, 130 The exhaust gas at ℃ is directly discharged, and the exhaust gas has not been treated, which is easy to cause air pollution
