Carbon monoxide alarm detection is a high-tech electronic product that detects the concentration of carbon monoxide leakage. It can effectively prevent the loss of carbon monoxide leakage to enterprises! The application of carbon monoxide alarm has certain regulations. Carbon monoxide alarm is a fixed type Gas alarms are difficult to change once installed, so the following aspects should be paid attention to when applying carbon monoxide alarms!
First: Find out the possible leakage points of the device to be monitored, analyze their leakage pressure, direction and other factors, and draw a distribution map of the probe position. According to the severity of the leakage, it is divided into three levels: I, II, and III.
Second: According to specific factors such as the airflow direction and wind direction of the place, determine the direction of the toxic gas leakage when a large amount of leakage occurs.
Third: According to the density of the leaking gas (greater than or less than the air), combined with the air flow trend, synthesize a leaking three-dimensional flow trend graph, and make an initial setting plan at the downstream position of the flow.
Fourth: Investigate whether the leak state of the leak point is a slight leak or a spray. If it is a slight leak, the location of the set point should be closer to the leak point. If it is a spray-like leak, stay slightly away from the leak point. Based on these conditions, the final point setting plan was drawn up. In this way, the quantity and variety to be purchased can be estimated.
Fifth: For places where there is a large toxic gas leak, a detection point should be set every 10-20m apart according to relevant regulations. For small, non-continuously operating pump rooms that are not on duty, attention should be paid to the possibility of toxic gas leakage. Generally, a detector should be installed at the downwind.
Sixth: For media with a gas density greater than air, the detector should be installed on the lower plane below the leak point, and pay attention to the characteristics of the surrounding environment. For places prone to accumulate toxic gases, special attention should be paid to the setting of safety monitoring points.
Seventh: For the open toxic gas diffusion and escape environment, if the lack of good ventilation conditions, it is easy to make the combustible gas content in the air of a certain part close to or reach the lower explosive limit concentration. These are safety monitoring that cannot be ignored point. According to the analysis results of on-site accidents, more than half of them were caused by incorrect installation and calibration. Therefore, it is necessary to introduce correct installation and calibration precautions to reduce failures
