Problems solved by technology
[0005] The purpose of the present invention is to provide a method for on-site detection of oil fume concentration and an on-site detector for oil fume concentration, which breaks through the previous detection mode of "collection-dissolution-analysis" and solves the problem of convenient, accurate, sensitive and fast on-site detection of most edible oils. Problems with the concentration value of cooking fume produced by heating oil and some non-edible oils

Embodiment 1
[0027] Embodiment one sees figure 1 According to the oil fume concentration detection principle and technology proposed by the present invention, a specific on-site detector for oil fume concentration can be designed. The on-site oil fume concentration detector in the embodiment includes a tubular thermal reaction chamber 4 with an air inlet 19 and an air outlet 10. The sequence from the air inlet to the air outlet is a thermal reaction section 5, a cooling section 8, and a detection section 9. Its cooling is a bell-mouth shape with a diameter from small to large, and of course it can also be other shapes with a gradual change in diameter. The tubular thermal reaction chamber is provided with a fan 1 at the air inlet, and a heating element 6 and a heating element support are arranged in the thermal reaction section. 7. A carbon dioxide gas detector 11 is installed in the detection section, and a thermocouple probe of a temperature display 20 is inserted into the thermal reacti...

Abstract
A on-site measuring method for oil smoke concentration and its on-site measuring apparatus, which is to employ manual control chemical reaction to fully oxygenate oil smoke in the air into carbon dioxide and water and to create a relationship between oil smoke concentration and carbon dioxide concentration, and to calculate the oil smoke concentration through detecting the changes of carbon dioxide concentration in the air before and after reaction. The detecting apparatus comprises a tubular heat reaction chamber with air inlet and outlet, wherein from the inlet to outlet orderly located thermal reaction section, cooling section, detecting section. And its cooling section is in the shape of bellmouthing with diameter increasing; and a fan is located in the air inlet of the tubular thermal reaction chamber. A heating element and its support are located in thermal reaction section and a detector for carbon dioxide is located in the detecting section.
Description
technical field [0001] The invention relates to a detection method and equipment thereof, in particular to a detection method and equipment for oil fume concentration. Background technique [0002] Most human activities are carried out indoors. Pollution in the indoor environment can lead to various diseases. Cooking fumes and irritating odor gases are one of the main sources of indoor environmental pollution. When the cooking temperature is higher than 130°C, oil fume will start to be produced from the edible oil, which will cause damage to people's respiratory and circulatory systems. Especially when the temperature reaches 230-280°C, some carcinogens may be produced in the oil fume. According to the analysis of Taiwan's Department of Health, the proportion of Taiwanese housewives suffering from lung cancer remains high. The main reason is that they have been in an environment polluted by cooking fumes for a long time. A survey in Nanjing found that 51.6% of lung squam...
