Description

Technical Field

[0001] The utility model relates to the technical field of smoke monitoring equipment, in particular to a CEMS sampling and filtering device. Background Art

[0002] As we all know, in the process of daily life, the environment is an important place for human survival, and the protection of the environment is an unchanging topic under the changing times. The CEMS system is a system for inspecting, sampling, monitoring and maintaining flue gas in the atmosphere. It conducts specific research and cleaning of flue gas through specific details. Flue gas filtration is of utmost importance for environmental protection. The most common existing flue gas monitoring equipment is the smoke detector; the smoke detector is a device used for filtering and detecting flue gas in the process of daily life, and it has been widely used in the field of environmental protection; when the existing smoke detector is used, the smoke detector is first started, and the output end of the smoke detector is fitted with the smoke discharge site, and the smoke is absorbed for detection; it is currently found in the use of smoke detectors that since most smoke is discharged in combination with smoke and impurities, a large amount of impurities will appear in the process of the smoke detector absorbing the smoke, so the impurities in the smoke need to be filtered.

[0003] To this end, the Chinese utility model patent with announcement number CN217332347U in the prior art discloses an anti-clogging CEMS sampling device, including a sampling tube and a cleaning mechanism. The cleaning mechanism is installed inside the sampling tube, and the cleaning mechanism is composed of a solenoid valve A, a solenoid valve B, a blowing pipe, a solenoid valve C, a discharge pipe, a solenoid tube D, a collection box and a sealing cover. A solenoid valve A is installed on the side near the entrance end of the sampling tube. After sampling is completed, the solenoid valve A and the solenoid valve B are closed, the solenoid valve D is opened, and then the solenoid valve C is closed after being quickly opened. When the solenoid valve C is opened, the gas to be measured can enter the side of the sampling tube near the exhaust end along the blowing pipe. The gas flowing into the sampling tube will be blown into the discharge pipe, and the impurities in the sampling tube will be blown during the circulation process, driving the impurities from the discharge pipe position into the collection box for collection, thereby avoiding clogging of the sampling tube by impurities.
