Application Publication Number: CN107151937 A Retention of damp and hot air in a closed hood of a paper machine drying section of a paper machine of a Shaanxi University of Science and Technology may reduce the ability of the paper to evaporate moisture and lead to the decrease of the drying rate due to the evaporation rate However, there is a downward trend, which is directly discharged to the outside but causes heat waste. An exhaust gas condensing water circulation device is provided for circulating steam condensate through a central circulation evaporator and a compressor through moist heat steam generated by the heat exchanger, generated condensed water and lower quality hot steam. Condensate evaporation process does not require additional steam,
