The invention relates to a drying heat recovery and utilization system of a coating machine, which comprises a drying box, a combustion furnace, a damp exhaust fan and a heat exchanger. The damp exhaust air outlet of the connecting pipe between the drying box and the combustion furnace is connected with the damp air inlet of the heat exchanger. The heat exchanger is connected in series between the damp exhaust air outlet and the damp exhaust air inlet of the heat exchanger, and the compensating air inlet and the heat exchange of the pipeline connecting the combustion furnace and the drying box are connected. The heat recovery outlet of the exchanger is connected, the air outlet of the drying box is connected with the air inlet of the combustion furnace, the air inlet of the drying box is connected with the air outlet of the combustion furnace, and the fresh air compensation outlet of the heat exchanger directly supplements the outside air. In order to reduce the loss of heat from damp exhaust, a heat exchanger is connected in series with the exhaust pipe of the damp exhaust fan, so that the external air can be directly added to the compensating air inlet above the pipeline connected with the combustion furnace and the drying box after heat recovery of the heat exchanger, thus avoiding the heating of the external supplementary air by the combustion furnace, greatly reducing the use of natural gas and saving energy.

一种涂布机干燥热回收利用系统
本专利技术涉及干燥热回收
,具体涉及一种涂布机干燥热回收利用系统。
技术介绍
如图1所示,涂布纸张干燥采用天然气燃烧炉气翼热风循环干燥箱烘干,蒸发掉的水分蒸汽经排潮风机排掉。为了平衡干燥箱之间的风压,热风进口上方安装了补偿口补充外界空气。在实际使用过程中,我们的干燥箱设定温度根据产品种类在150°到220°之间,排潮温度在90°至160°之间,排潮风机流量为每小时9500m³,蒸汽排掉的同时也带走了每小时9500m³流量的热量,造成很大的天然气资源的浪费。
