Monitoring device for primary air pipe of boiler, and monitoring method thereof

Abstract

The invention discloses a monitoring device for a primary air pipe of a boiler, and a monitoring method thereof, and relates to the technical field of pressure monitoring. The invention discloses a monitoring device and a monitoring method. According to the invention, when the internal pressure of an air pipe is increased to be greater than the elastic force of a return spring, a sliding plate slides upwards along the inner side wall of a pneumatic shell under the action of the pressure, a pull rope is fed at the moment, a sliding ring slides downwards along the outer side wall of a sliding rod under the action of an air valve spring, then a supporting plate pulls a sealing plate to rotate inwards along the outer side wall of a fixing ring, and a blockage blowing pipe is opened, at this moment, air compressed by an air compressor enters the air pipe through the blockage blowing pipe, blowing operation is realized, the situation that when the internal pressure of the air pipe is normal, air in the air pipe enters the air compressor via the blockage blowing pipe to influence use of the air compressor, is prevented, automatic opening for the blockage blowing pipe when the internal pressure of the air pipe reaches a threshold value is realized, effective blowing for the air pipe is realized, the detonation condition of the air pipe is prevented, and the service life of the air pipe is prolonged.

Description

technical field [0001] The invention relates to the technical field of pressure monitoring, in particular to a boiler primary air pipe monitoring device and a monitoring method thereof. Background technique [0002] Pressure monitoring is the monitoring of pressure changes during mechanical ventilation. Airway pressure is usually monitored. The pressure sensor is mostly at the proximal end, expiratory end or inspiratory end of the connecting tube. The change of airway pressure can be more accurately reflected near the Y-shaped tube, while it is easy to underestimate at the exhalation end and easy to overestimate at the inhalation end, but the overall difference is not significant. It can be instantaneous monitoring, dynamic monitoring, numerical monitoring or graphic monitoring. [0003] With the existing equipment, when monitoring the primary air duct of the boiler, due to the powder accumulation in the primary air duct of the boiler, which has not been purged in time or...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems existing in the prior art when the primary air duct of the boiler is being monitored, and the dust accumulation in the primary air duct of the boiler is not purged in time or The pressure control of the air duct during operation is not good, and there are dangers of deflagration and degree ducts, and it is impossible to effectively reduce the blockage of the primary air duct or the deflagration of the primary air duct, which makes the equipment unable to operate safely and stably. A boiler primary air duct is proposed Monitoring device and monitoring method thereof
