Description

Technical Field

[0001] This utility model relates to the field of paper breakage steam recovery technology, and in particular to a paper breakage steam recovery device. Background Technology

[0002] In existing paper drying units, the steam system typically lowers the drying cylinder temperature as quickly as possible when paper breaks in the drying cylinder section to facilitate paper feeding. This is achieved through a paper-break venting system, which opens a bypass valve at the paper-break point to release some steam, thus quickly reducing the cylinder temperature to the required level. However, this released steam enters the atmosphere through the paper-break vent pipe. Untreated steam discharge causes environmental and noise pollution and wastes heat energy, especially in paper mills near residential areas, impacting residents' lives. With increasing societal development and growing emphasis on environmental protection and energy utilization, heat recovery from paper-break venting is a crucial issue that must be addressed, necessitating improvements.

[0003] CN 205874834 U discloses a paper breakage vapor recovery device, including an exhaust pipe, a condenser, a hot water collection tank, an inlet pipe, an outlet pipe, a control device, and a detection device. The exhaust pipe, the inlet pipe, and the outlet pipe are respectively connected to the condenser. The second end of the outlet pipe is connected to the hot water collection tank. The control device includes a first control valve and a second control valve. The first control valve is installed on the inlet pipe, and the second control valve is installed on the outlet pipe. The detection device includes a first sensor for detecting the pressure of the exhaust pipe.

[0004] In use, existing devices bring hot water vapor into contact with water flow, but it takes a long time for the gas to enter the liquid, resulting in low heating efficiency. In addition, the condenser is large, making it difficult to quickly replace the water flow after heating. Therefore, we propose a paper breakage steam recovery device. Utility Model Content
