    [ Focus on Chemical Machinery and Equipment Network ] With the rapid development of industry, more and more waste gas and waste are emitted by industry, and the damage to humans and the environment is becoming more and more serious.
    Among the many pollutants, the harm of one kind of pollutant is slowly increasing, which should attract more and more attention, it is dust.
    Dust refers to solid particles suspended in the air with a particle size of less than 75μm.
    Don't look at it, it can't be seen or touched, but it has a fatal hazard.

     
    Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipment
    Its hazard to the environment: dust floating in the air can cause other harmful substances to adhere to it, causing serious air pollution.
    Because dust exists in the air as particles floating, the inhalation of organisms can cause various diseases, and the surface of cultural relics, historic sites, and buildings will be corroded and polluted.
    In addition, a large amount of dust suspended in the air can reduce the visibility of the atmosphere, promote the formation of smog, and easily form haze weather.
    At the same time, it also affects the heat radiation of the sun and affects the growth of plants.

     

    In addition, the main hazard to production is that the dust in the air in the workplace is attached to high-level and precision instruments and meters, which can reduce the accuracy of these equipment; attached to the transmission and running parts of the machinery and equipment, causing severe wear and shortening the service life ; Dust can degrade the quality of certain chemical products, mechanical products, and electronic products, such as paint, film, miniature bearings, motors, integrated circuits, capacitors, televisions, video recorders, cameras, etc.
    ; Influence, reduce work efficiency.

     

    As our country attaches importance to industrial production pollution and labor rights, there are related laws and regulations on dust concentration in our country, and some dust allowable concentration standards in special working environments have also been formulated.
    This also reflects the importance and necessity of dust prevention, dust removal and dust detection.
    The dust monitoring industry has also begun to develop rapidly, with the help of monitoring instruments .

     
    Monitoring instrument
      The dust tester is a main instrument used for the measurement of dust concentration in the environment.
    It uses laser as the light source and adopts the principle of light scattering method to accurately measure the dust concentration in the environment in real time.
    It is mainly used to detect the dust concentration in the ambient air.
    The types of dust meters are divided into: laser dust meters, online continuous monitoring dust meters, portable dust meters, etc.
    , dust meters are widely used in disease prevention and control centers, mines, metallurgy, power plants, Online monitoring of chemical manufacturing environment, etc.

     

      Direct-reading dust concentration measuring instrument is an instrument used to measure the mass concentration of solid particles suspended in the air, and can display concentration values ​​or output concentration signals.
    The measuring instrument is mainly used for the measurement of dust concentration in environmental protection, metallurgy, health and epidemic prevention, mining, railways and other industries or departments.
    Its principle is to use the light transmission method, light scattering method, β-ray method and piezoelectric crystal method to signal the dust concentration.
    Converted into electrical signal, and then displayed by the secondary meter.
    According to whether there is a pre-separation device, it is divided into a total dust concentration measuring instrument and a respirable dust concentration measuring instrument (including some single particle size separation instruments).
    It is mainly composed of dust concentration conversion components, sampling head, suction pump, power supply, circuit and other parts.
    Some measuring instruments also have functions such as flow meter , sampling time display or setting, sampling volume display or setting, and signal output.

     
    Flowmeter
      The portable dust meter is convenient to carry.
    It only needs to be sampled on site when in use, and 60 sets of instantaneous data can be obtained per minute, and the high, low and average data can be visually seen in a short time.
    When law enforcement officers carry the instrument to monitor the surroundings of the construction site, through the data displayed on the instrument, they can immediately determine whether there is any illegal construction behavior on the construction site and keep relevant evidence in time.
    It uses the principle of light scattering to detect the aerosol concentration corresponding to the particle size of PM1, PM2.
    5, PM4, PM10, and the measurement range is 0.
    001 to 150 mg/m3.
    It can be used for indoor and outdoor monitoring, especially suitable for difficult conditions.
    Environmental monitoring of industrial workshops, construction sites, etc.

     

      In the precision machinery production workshop, the requirements for the cleanliness of the workshop are very high.
    Dust sensors are equipment in almost every precision electronics workshop*.
    Dust sensor is an instrument used to measure the number and size distribution of dust particles per unit volume in a clean room.
    It has the advantages of fast test speed, dynamic distribution width, no human influence, etc.
    It is the main monitoring instrument for manufacturers and scientific research departments such as spray paint and environmental protection products.
    Equipped with such an instrument for monitoring particle concentration, it can easily understand the dust situation in the workshop while in the office, and realize the intelligent experience of the product.

     

      Dust pollution is a big hazard.
    Are these monitoring instruments to help? Do you know any more?
