Abstract
The invention discloses a non-leakage draining system for high-and-low pressure steam separation. The non-leakage draining system sequentially comprises a boiler, a paper board production line heat consuming system, a non-leakage draining system, a constant-pressure tank, a steam and water separator and a low-back-pressure recycling machine, all of which are connected through a pipeline in sequence. A water feeding pump inputs water into the boiler for heating, high-pressure crude steam is formed and conveyed to the paper board production line heat consuming system through a pipeline, the crude steam becomes mixed secondary steam of low-pressure water and saturated steam, and part of the secondary steam is exhausted through a siphon of the paper board production line heat consuming system. Most secondary steam is input into the constant-pressure tank after passing the non-leakage draining system, after the secondary steam is separated and dried through the steam and water separator, condensate enters the low-back-pressure recycling machine, the steam is input to a triple preheat cylinder to be used, and then the steam enters the boiler through a buffering tank to be circularly utilized. The high-pressure steam and the low-pressure steam are separated, and therefore after the steam is used, the non-leakage steam and condensate separated conveying is achieved, the heat loss of a steam heating system is reduced, the using efficiency is improved, and the production cost is reduced.
