In Zengcheng, Guangzhou, a male driver was suspicious of a sudden collapse when he waited to pass through the Lishui section of Phoenix Avenue and died after being rescued.
"traffic car" caused death?
According to informed sources, the driver may be blowing air conditioners in the car when it is off, leading to hypoxia poisoning.
In fact, long-term idle speed will not only increase the risk of carbon monoxide poisoning, but also cause other adverse effects such as engine carbon deposition due to the long-term excessive air-fuel ratio of the engine.
Measured: The data is amazing
Someone did a simulation experiment. The experimenter parked a car in the car paint booth, opened the car air conditioner and kept it in an external circulation state. The doors and windows were closed, and the carbon monoxide content in the car was detected at different times using a carbon monoxide detector.
0 minutes, the concentration of carbon monoxide in the car is 0ppm, and the temperature inside the car is about 20°C, which is comfortable;
1 minute, the concentration of carbon monoxide in the car is 5ppm;
3 minutes, the carbon monoxide detector warning light starts flashing;
5 minutes, the concentration of carbon monoxide in the vehicle was 65ppm, the detector warning light kept flashing and shaking;
15 minutes, the concentration of carbon monoxide in the car is 70ppm, the detector warning light keeps flashing and shaking;
In 25 minutes, the concentration of carbon monoxide in the car was 91 ppm, and the carbon monoxide detector warning light flashed and alarmed. There was a noticeable suffocation into the paint booth, and it became apparent after 1 minute that it entered the car.
Experts: Internal circulation of carbon dioxide can also be poisoned
Yao Xiaodong, director of the Department of Occupational Diseases of the First Affiliated Hospital of Zhejiang University and Director of the Center for the First Aid and Prevention of Poisoning in Zhejiang Province, said: “The space in the car is small. If the air in the car is set in the internal circulation, the human body will breathe, causing less oxygen in the car and exhaling. The carbon dioxide will be higher and higher.When the concentration of carbon dioxide in the car reaches a certain value, people will experience coma and cerebral hypoxia.When the carbon dioxide content in the air exceeds 1%, the person has a mild poisoning reaction; when more than 3 At the time of %, dyspnea begins; when it exceeds 6%, it will cause severe poisoning and even death."
The correct way to open the air conditioner in the car
Especially in the summer, do not open the air conditioner as soon as you get in the car. Because the temperature inside the vehicle is high, many accessories on the vehicle can easily emit toxic gases. Ventilation should be done first, and then open the external circulation, wait for the car temperature control at a relatively cool temperature and then open the internal circulation.
Water treatment Filter Element is a filter element used for water treatment and liquid filtration. It is mainly used to remove suspended solids, sediment, rust and other impurities in water, and improve the cleanliness and transparency of water. The filter element is divided into the following types: PP filter element is also called PP melt-blown filter element, which is a filter element made of polypropylene material, which has good filtering effect and corrosion resistance, and can be used to purify tap water, groundwater, chemical liquids, etc.; The wound filter element is refined by finely winding textile fiber yarns with good filtration performance on a porous skeleton. The yarn materials include polypropylene fiber, acrylic fiber, absorbent cotton fiber, etc. By controlling the winding tightness and thinness of the yarn during winding, filter elements of different precision can be made, which can effectively remove suspended solids and particulate impurities in various liquids, and have a high purification effect on various liquids; folded filter elements , is a deep filter core folded structure, large membrane filtration area, large flux. Low differential pressure, strong dirt holding capacity and long service life. There are a variety of filter fineness to choose from, with a wide range of applications. Good chemical compatibility, suitable for filtering strong acids, strong alkalis and organic solvents. Processed and formed by hot-melt welding technology, does not contain any chemical adhesives, no leakage, no secondary pollution.
