Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a sampling gun filter cartridge device, which effectively solves the problem that the glass fiber filter cartridge will be tightly attached to the filter cartridge wall due to the force of the air flow during sampling in the prior art sampling gun equipment. There is moisture in the air flow, and the glass fiber filter cartridge will absorb water and become soft. When the traditional method uses a column to take the glass fiber filter cartridge out of the sampling tube filter cartridge, it is easy to break the glass fiber, resulting in a decrease in its quality and a loss of detected components. Defects that lead to inaccurate experimental results

Abstract

The invention relates to a detection device for sampling particulate matter and gaseous pollutants contained in exhaust gas of a stationary pollution source, in particular to a filter cylinder device of a sampling gun. The filter cylinder device of the sampling gun comprises an outer cylinder, a sampling gun nozzle mechanism, a glass fiber filter cylinder and a filter cylinder taking device, wherein one end of the outer cylinder is open, a gas outlet for communication between the inside and the outside of the outer cylinder is formed in the tail end of the other end of the outer cylinder, the sampling gun nozzle mechanism is installed at the open end of the outer cylinder in a screwed mode, the filter cylinder taking device is installed on the sampling gun nozzle mechanism in a hung-connected mode and is located in the outer cylinder and is in sleeving connection with the glass fiber filter cylinder, and the open end of the glass fiber filter cylinder is connected with the sampling gun nozzle mechanism. The filter cylinder device of the sampling gun has the advantages that the filter cylinder device is simple in structure and convenient to use, the filter cylinder in the device is convenient to take and is not damaged, and a sampling-detecting result is more accurate.

Description

technical field [0001] The invention relates to a device for sampling and detecting particulate matter and gaseous pollutants in the exhaust gas of a fixed pollution source, in particular to a sampling gun filter cartridge device. Background technique [0002] At present, a sampling gun is used when sampling particulate matter and gaseous pollutants in the exhaust of fixed pollution sources. When using a sampling gun, a glass fiber filter cartridge must be installed in the filter cartridge of the sampling gun. When sampling, the muzzle of the sampling gun must be aligned with the airflow direction. Particles in the gas will be trapped in the glass fiber filter cartridge. After sampling, the glass fiber filter cartridge needs to be completely taken out for the next experiment. [0003] Due to the force of the airflow during sampling, the glass fiber filter cartridge will be tightly attached to the wall of the filter cartridge. The airflow contains moisture, and the glass fibe...
