Eight tips for installing flammable gas alarms

Once the fixed-point installation of the flammable gas alarm is in place, its position cannot be easily changed. According to the work experience accumulated over the years, the following points should be considered in specific applications.
(1) Find out which leak points are possible for the devices to be monitored, analyze their leakage pressure, direction, and other factors, and draw a probe position distribution chart, which is divided into three levels of I, II, and III according to the severity of the leak.
(2) Judging the leakage direction of combustible gas when a large amount of leakage occurs according to specific factors such as the airflow direction and wind direction of the location.
(3) According to the density of the leaked gas (greater or less than air), combined with the air flow trend, a three-dimensional flow trend chart of the leak is synthesized, and an initial set point scheme is made at the downstream position of the flow.
(4) Investigate whether the leak state at the leak point is slight leak or spray. If it is a slight leak, the set point should be closer to the leak point. If it is a spray leak, stay away from the leak. Synthesizing these conditions, the final set-up plan was drawn up. In this way, the quantity and variety to be purchased can be estimated.
(5) For places where there is a large amount of flammable gas leakage, a detection point shall be set every 10-20m apart according to relevant regulations. For small and discontinuously running pump rooms that are not on duty, you need to pay attention to the possibility of flammable gas leakage. Generally, a detector should be installed at the downwind.
(6) For places with hydrogen leakage, the detector should be installed on the plane above the leak point.
(7) For media with a gas density greater than air, the detector should be installed on a plane below the leak point, and pay attention to the characteristics of the surrounding environment. For places where flammable gas is likely to accumulate, special attention should be paid to the setting of safety monitoring points.
(8) For open flammable gas diffusion and escape environment, if there is no good ventilation condition, it is easy to make the flammable gas content in the air of a certain part close to or reach the lower explosive concentration. These are safety monitoring points that cannot be ignored. .

What disease can dry air cause

It will not lead to specific diseases, but only some hazards.

1. It is easy to cause excessive loss of body water, infect diseases and accelerate aging. In a dry environment, when we get up every morning, we will feel dry mouth, tight muscles and low mood. Especially for women, the skin's muscle fibers are composed of a large amount of water-soluble collagen. Drying makes the muscle fibers shrink due to rapid water loss. Over time, the muscle fibers may break, and the skin will have unrecoverable wrinkles and aging.

2. Easy to cause the spread of bacteria. Dry air is the main reason for the increase of dust and suspended particles, while bacteria can not exist alone and often adhere to dust. The elderly and young children have weak physical resistance and are vulnerable to bacteria and viruses. Warm and dry is the best environment for the breeding and transmission of many viruses and bacteria.



Tips for reducing air drying:

1. Put the peel on the heater

Usually after eating oranges and grapefruits, don't throw away the peel. The moisture content of these peels is large. If the car information is placed on the heating, it can also play a certain humidification effect. In addition, it can also emit a fragrant fruit fragrance and purify the air.

2. A basin of water with a wet towel

Still put a basin of water, but put a wet towel on the basin. Half of the towel is immersed in the water and half is out of the water. The contact surface between water and air in the washbasin is small, so it volatilizes slowly. After building a wet towel, the contact surface becomes larger, and the humidification effect is naturally much better. Moreover, the towel can continuously absorb water from the basin and is not easy to dry.

Medical experts point out that under normal circumstances, the appropriate health humidity of the human body is between 45% RH and 65% RH, while in autumn and winter, the air humidity in northern China is generally below 30% RH, which can not meet the health requirements of the human body.

Another simple and effective way is to put an Aroma Diffuser in the room. It can take effect effectively and immediately, humidify the air and solve the problem of air drying. The ultrasonic aroma diffuser is required, and the fog is sprayed out through vibration
