Belongs to the field of steam application and energy conservation, and relates to an automatic group drainage device for a steam lock.

Background

In industrial production, steam is widely used as a heating medium. Steam is discharged in time after being discharged into condensed water in the equipment, otherwise, the efficiency of the equipment is reduced and the product quality is influenced due to water accumulated in the equipment. In addition, the reliability and service life of the equipment are also greatly affected by water accumulation problems. Equipment water accumulation can also cause water hammer to endanger equipment and personnel safety. However, if the phenomenon of steam discharge occurs when condensed water is discharged, energy waste and enterprise production cost increase are caused, and sometimes, the production efficiency of equipment is reduced by direct steam discharge. Therefore, for steam-consuming equipment, especially for drying cylinder equipment used in industries of paper making, printing and dyeing, textile, chemical industry, tobacco, grain processing and the like, the problems of water drainage and steam resistance are a pair of problems which are contradictory and difficult to solve. In the actual production process, the problem cannot be well solved in most enterprises, and either equipment accumulates water or steam leaks. Most customers have to accept leakage steam for water accumulation elimination in order to ensure production, which results in a great energy waste.

The invention relates to an anti-steam lock automatic group drainage device, which is a special device for effectively solving the contradiction of timely draining condensed water and avoiding steam leakage and simultaneously realizing efficiency improvement, energy saving and prolonging the service life of the device.
