Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of petroleum chemical industry, specifically an intelligent monitoring alarm device applied to petroleum chemical industry. BACKGROUND

[0002] As a pillar industry of national economic development, the production process of petroleum chemical industry is complex and continuous, covering high-temperature, high-pressure, flammable and explosive environments. In the production process, various equipment is in a high-intensity operating state for a long time, and is prone to failure due to factors such as fatigue and corrosion. Once a leakage, explosion or other accident occurs, the consequences are unpredictable. In the past, the monitoring method relied on regular manual inspection and basic sensors, which was limited by manpower, time and detection accuracy, and it was difficult to track and warn potential hazards and sudden abnormalities in operation comprehensively and in real time. At present, the rapid development of big data, cloud computing and sensor technology provides a strong opportunity for the petroleum chemical industry to break through the monitoring bottleneck, giving birth to an intelligent monitoring alarm device that can comprehensively and intelligently perceive the production state and timely issue an alarm to meet the urgent needs of the industry for safe production and efficient operation and maintenance.

[0025] When working, first install the device in the petrochemical production area through the rear hole plate of the shell 11 and the bolt. When no combustible gas leakage is detected, the air exhaust fan 12 runs at low power to ventilate, the airflow is gentle, the wind direction cover 111 is deflected at a small angle or not deflected, the windward inner plate 131 of the louver 13 is stationary, and the basic ventilation is maintained and foreign matter is prevented from entering. When combustible gas leakage is detected, the combustible gas detector 14 feeds back a signal, the power of the air exhaust fan 12 is increased, the strong suction makes the airflow quickly rush in, the wind direction cover 111 is deflected at a large angle to form a horn shape, and at the same time, the strong airflow impact makes the windward inner plate 131 rotate against the torsional spring resistance, increasing the ventilation volume to quickly exhaust the combustible gas.

[0027] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0028] Working principle: when working, first, through the hole plate at the rear side of the shell 11 cooperate with the bolt, install the device in the petrochemical production area at the appropriate position, when no combustible gas leakage is monitored, the air extractor fan 12 runs at low power, and the indoor is normally ventilated, at this time, due to the relatively gentle airflow, the airflow drives the wind direction cover 111 to deflect at a small angle or not deflect into the shell 11, and the inner windward board 131 of the louver 13 is in the initial static state, maintaining a certain ventilation to maintain the basic air exchange in the room, while preventing a large amount of foreign matter from entering the inside of the device, when the combustible gas detector 14 detects that there is combustible gas leakage in the surrounding environment, it will quickly feed back the monitoring result to the control module of the air extractor fan 12, after receiving the signal, the control module of the air extractor fan 12 controls the air extractor fan 12 to increase the power, at this time, the air extractor fan 12 with larger power generates stronger suction, so that the airflow quickly flows into the inside of the device, the airflow drives the wind direction cover 111 to deflect at a large angle into the shell 11 and become a horn shape, at the same time, due to the strong airflow impact caused by the increase of the power of the air extractor fan 12, the inner windward board 131 rotatingly arranged in each leaf plate of the louver 13 starts to rotate, the torsional spring is sleeved and fixed on the shaft at the upper side position of the left and right sides of the inner windward board 131, one end of the torsional spring is fixed on the inner wall of the rotating hole, under the action of the strong airflow, the inner windward board 131 rotates against the resistance of the torsional spring, thereby increasing the ventilation of the louver 13 and accelerating the air exchange speed between indoor and outdoor, which is beneficial to quickly discharge the combustible gas, after the power of the air extractor fan 12 increases, the prong hole shaft tube 121 fixed at the front end of the shaft of the air extractor fan 12 rotates at high speed, since the screw end prong rod 122 is slidingly arranged in the prong hole shaft tube 121, and the screw end prong rod 122 is threadedly connected in the wire hole of the wire hole seat 113, under the driving of the high-speed rotation of the prong hole shaft tube 121, the screw end prong rod 122 will slide in the prong hole shaft tube 121 along the thread direction of the screw rod at a high speed, with the continuous high-speed rotation of the air extractor fan 12, the screw end prong rod 122 slides at a high speed, when reaching a certain position, the screw end prong rod 122 will collide with the surface of the impact clapper 112 in the moving stroke, the sound generated by the collision will be efficiently conducted to the indoor through the horn-shaped wind direction cover 111 to alarm, reminding the on-site personnel to pay attention, after the collision, the screw end prong rod 122 will slide to reset under the limitation of the impact clapper 112, and continuously and quickly collide for early warning under the driving of the air extractor fan 12 (under the low power state of the air extractor fan 12, the screw end prong rod 122 will only collide with the impact clapper 112 at a long interval to remind the normal operation, otherwise, it needs to be overhauled).

[0029] It should be noted that the combustible gas detector 14 can be selected from, for example, HIGON SOLAR Ex681 (based on hydrogen flame ion monitoring technology, continuously measuring the low explosion limit of exhaust gas), GM-YH55S (using high-performance gas-sensitive elements and catalytic combustion sensors, stable and strong anti-interference ability), QB2000N (a high-performance intelligent gas sensor is used to monitor online), SP-1102 (an American Huarui explosion-proof type, catalytic combustion sensor anti-poisoning interference), PGM-1600 (an American Huarui composite type, has a combustible gas dual-range sensor and is portable), MCXL-W (made in Canada, suitable for harsh working conditions, catalytic combustion and electrochemical sensor combination), and the like.

[0030] It should be noted that in this document, relational terms such as first and second and the like can merely be used to distinguish one entity or action from another, without necessarily requiring or implying that there are any such actual relationship or order between or among the entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
