Description

Technical Field

[0001] The utility model relates to the technical field of automobile detection equipment, in particular to an evaporation sealed cabin for detecting the volatility level of hydrocarbons. Background Art

[0002] There are three main sources of motor vehicle pollution: exhaust emissions, crankcase blowby and fuel evaporation. With the rapid increase in the number of motor vehicles, the impact on the atmospheric environment is becoming more and more serious, especially the emission of particulate matter from automobiles in cities is the culprit of the smog phenomenon. Therefore, in order to fundamentally govern the environment, it is necessary to strictly control and test automobile emission standards, and the closed evaporation chamber is a device used for automobile emission testing.

[0003] There is a closed evaporative cabin for automobile emission detection on the market. The device uses a circulating air duct on the closed cabin, uses the circulating air to lead the exhaust gas emitted by the automobile to the detection probe, and uses the detection probe and the detection module to detect it. When the detection is completed, the air in the closed cabin is cleaned by the circulating air to avoid the retention of pollutants in the closed cabin. However, this method has limited effect on the air treatment in the closed cabin and is inefficient. Some particulate pollutants will still remain in the closed cabin, which will affect the next detection. At the same time, the function of the device is relatively single, and it cannot detect the airtightness of the detected vehicle.

[0004] For example, Chinese patent publication number CN219121633U discloses an efficient closed evaporation cabin for automobile emission detection. The evaporation cabin is provided with a drainage trough and a sewage outlet at the bottom of the closed cabin, and a water mist nozzle and a water pump are provided at the top of the closed cabin. When the automobile exhaust emission detection is completed, the water pump is started to spray water mist into the closed cabin through the water mist nozzle, and the discharged particulate matter in the closed cabin is flushed with water mist, thereby achieving the purpose of quickly cleaning the air in the closed cabin to avoid residual dust from affecting subsequent detection. At the same time, when the automobile is started to discharge exhaust gas, the temperature in the closed cabin will also rise accordingly, and the water mist dust removal method can also achieve the purpose of cooling. Through this design, the detection efficiency of the device can be effectively improved.

[0005] The existing technology has the following problems:

[0006] Because water vapor, particles and gases all move disorderly in the air, water vapor and particles can easily escape from the sealed cabin. Then the water pump spraying water mist into the interior through the water mist nozzle greatly reduces the cleaning effect on the particles, resulting in a large number of particles still remaining in the evaporation sealed cabin after the test is completed.
