Embodiment Construction
[0036] Please refer to the attached Picture 1-1 to attach Figure 13 As shown, the present invention is a waste heat recovery device for the tail gas of a setting machine, which consists of several heat exchange boxes 2, a casing 3, an exhaust gas inlet 4, a fresh air inlet 5, an exhaust gas outlet 6, and a heat exchange air outlet 7 and other parts are assembled.
[0037] Wherein, the number of the heat exchange boxes 2 is 1+N arbitrary combinations, wherein, N≥0. The plurality of heat exchange boxes 2 are stacked and connected in series. Two adjacent heat exchange boxes 2 are connected through the casing 3 so as to facilitate fresh air to circulate in the two heat exchange boxes 2 .
[0038] The exhaust waste heat recovery device of the sizing machine further includes a base 1, and the plurality of heat exchange boxes 2 are stacked on the base 1 and arranged in two rows. Of course, it is also possible to directly use the heat exchange box 2 without the base 1 for heat ex...

The invention relates to recovery equipment for tail gas waste heat of a setting machine. The recovery equipment comprises multiple heat exchange boxes, housings, tail gas inlets, fresh air inlets, tail gas outlets and heat exchange air outlets. The heat exchange boxes are connected in series in a stacked manner. Every two adjacent heat exchange boxes are connected through the corresponding housing. According to two heat exchange boxes, the tail gas inlet and the heat exchange air outlet are formed in one heat exchange box, and the tail gas outlet and the fresh air inlet are formed in the other heat exchange box. The pipe walls of heat exchange pipes of the recovery equipment for the tail gas waste heat of the setting machine are thin, so that the mass of the heat exchange pipes is low, the heat conduction performance is good, the heat exchange speed is high, and the effect is good; and concave-and-convex structures are formed in the heat exchange pipes, and a certain slope is formed, so that structural strength is improved, the heat exchange area is increased, tail gas can be disturbed, heat exchange efficiency is high, and heat exchange is sufficient.
Description
【Technical field】 [0001] The invention relates to a waste heat recovery device, in particular to waste heat recovery equipment for the tail gas of a setting machine, and belongs to the technical field of environmental protection equipment. 【Background technique】 [0002] Styling machine is one of the main energy-consuming equipment in the textile dyeing and finishing industry. It uses hot air to dry, finish and set the fabric. The hot air temperature required by a general setting machine is about 200°C, and its exhaust gas temperature is generally around 170°C. Therefore, a large amount of waste heat is discharged into the air, resulting in huge energy waste and heat pollution to the environment. [0003] At present, the heat recovery and utilization of the exhaust gas of the sizing machine is mainly through the following methods: the high-temperature exhaust gas is exchanged with fresh air in the heat exchange device, and the hot air is obtained to supplement the oven of th...
