Steam lock breaking device and method for steam system drain valve

Abstract

The invention relates to a steam lock breaking device and method for a steam system drain valve. A dryer of the breaking device is connected with external equipment through a drain channel, a floatingball type drain valve is arranged on the drain channel, a temperature sensor is arranged on the drain channel and used for obtaining real-time temperature information of the drain channel, and an exhaust hole is formed in the floating ball type drain valve and communicated with an exhaust pipeline. An exhaust valve is arranged on the exhaust pipeline, a controller is connected with the temperature sensor and the exhaust valve, and the controller controls the exhaust valve to be opened according to the real-time temperature information, obtained by the temperature sensor, of the drain channel.According to the steam lock breaking device and method for the steam system drain valve, the common steam lock problem of dryer drain is solved, reliable and stable operation of the dryer is guaranteed, and compared with the steam lock breaking scheme that a hole is formed in a drain valve body and an exhaust air valve is additionally arranged or the exhaust air valve is arranged in the drain valve to keep a certain leakage amount, the device and method have the advantages that drain efficiency of the drain valve can be greatly improved, and a large amount of steam energy is saved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a steam lock breaking device and a breaking method for steam traps in a steam system. Background technique [0002] In the prior art, most of the dryers rely on siphon pipes and drain pipes to introduce the mixture of steam and condensed water into the ball float trap, and the ball float trap discharges the condensed water through the principle of density difference and retains the steam. If a large amount of steam in the mixture enters the trap and the pipes connected to it occupy the drain channel of the condensed water, the condensed water will not be able to be discharged into the trap, forming a steam lock. Only after the steam in the channel is pre-condensed and condensed into liquid water can the vapor lock be broken. If very little non-condensable gas in the steam enters the hydrophobic channel, it will be difficult for the hydrophobic channel to break...
