Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] Such as figure 1 , is a structural schematic diagram of the present invention, which is a gravure printing waste gas waste heat recovery system device, including a waste gas recovery system and a fresh air heating system. The waste gas recovery system includes a waste gas heat exchange pipe 1, an exhaust fan 2 and an exhaust pipe 3 connected in sequence, The exhaust gas heat exchange pipe 1 is installed with a purification heat exchange component group; the fresh air heating system includes a fresh air heat exchange pipe 4 with two fresh air inlets, and a heat pipe heat exchanger 5 and an oven air intake device 6 are installed on the fresh air heat exchange pipe. One end of the head of the waste gas heat exchange pipe has a printing waste gas inlet device 7, as can be seen from the figure, the printing waste gas inlet device is the air exhaust port of the oven o...

Abstract

The invention discloses a waste heat recycling system device for intaglio printing waste gas. The waste heat recycling system device comprises a waste gas recycling system and a fresh air heating system. The waste gas recycling system comprises a waste gas heat exchange pipeline, an exhaust fan and an exhaust pipeline which are sequentially connected with one another, and a purification heat exchange assembly is mounted on the waste gas heat exchange pipeline; the fresh air heating system comprises a fresh air heat exchange pipeline with two fresh air inlets, and heat-pipe heat exchangers and oven air inlet and suction devices are mounted on the fresh air heat exchange pipeline. The waste heat recycling system device has the advantages that heat of waste gas and steam condensation water is collected in intaglio printing manufacturing procedures, fresh air which is fed into the system device is preheated via heat exchange structures, then preheated fresh air is fed into air inlets of steam heat exchangers of various units of an intaglio printing machine and is used for drying printing ink after being heated by the steam heat exchangers, accordingly, energy consumption can be reduced, and the waste heat recycling system device has excellent economic value.

Description

technical field [0001] The invention relates to a gravure printing waste gas waste heat recovery system device and an application method thereof, belonging to the equipment of the gravure printing industry. Background technique [0002] Exhaust gas waste heat recovery is widely used in power plants, steam boilers and other fields with a large amount of high-temperature exhaust gas. The heat in the exhaust gas is used to preheat media such as water or air through a cold and heat exchanger, making full use of energy and reducing energy consumption. , improve the economic efficiency of the enterprise. [0003] Waste heat recovery from exhaust gas can also be applied in gravure printing. High temperature air is mainly used for drying and curing ink. Since the ink is usually made of high-fraction resin raw materials, it has certain requirements on the drying temperature. If the temperature is too high, it will cause the ink to dry, and the inside of the ink will not be fully dr...
