Description
Technical field
The present invention relates to a kind of gaseous diffusion collection tube, particularly about a kind of wet type parallel-plate gaseous diffusion collection tube.
Background technology
The kind of atmosphere pollution can be divided into gaseous contaminant and aerosolized pollutant by its existence, and both are mixed in the atmospheric environment uniformly.When the component of gaseous contaminant and aerosolized pollutant and concentration are monitored, separate two pollutants effectively, avoiding the phase mutual interference between two pollutants is the key of accurately measuring concentration.Since Gorrnely and Kennedy (1949) proposed to separate the gas-solid pollutant with anemostat, this technology had been widely used in the sampling process of Atmospheric Trace pollutant.
Desirable anemostat is that a kind of inwall is covering and can adsorb exchange gas agent pipeline to be measured, and what this pipeline can 100% is captured in gas composition to be measured on the tube wall, makes passing through of gasoloid 100% simultaneously.According to shape, anemostat can be divided into circle, annular, parallel plate type; According to the existence form of absorption liquid, anemostat can be divided into dry type and wet type again.Because the surface area of circular anemostat is less than annular and parallel plate type anemostat with girth, therefore, its arresting efficiency to gaseous contaminant is lower than annular and parallel plate type.And there is the saturated problem of absorption in the dry type anemostat, is not suitable for being applied to the state of continuous coverage.Therefore, anemostat commonly used at present is wet type annular anemostat and wet type parallel plate type anemostat.Wet type annular anemostat has following two remarkable shortcomings: 1, need rotation could guarantee that absorption liquid is uniformly distributed in tube wall, and rotation can bring frictional dissipation; 2, aerocolloidal flow process is disturbed in absorption liquid disturbance easily in pipe.Existing market has a kind of wet type parallel-plate anemostat, and it adopts the semi-permeable diaphragm structure of two-layer permeable watertight, and semi-permeable diaphragm one side is a gas circuit, opposite side passes through absorption liquid, the shortcoming of this design is: 1, semi-permeable diaphragm is softer, and is yielding, will disturb gas circuit when distortion; 2, semi-permeable diaphragm has certain transmitance to gas, and influence is to the arresting efficiency of pollutant; 3, because semi-permeable diaphragm is soft, can not large tracts of land cover, under the situation that guarantees arresting efficiency, the sample airshed can not be big, and then require high to the level that detects of subsequent detection.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind of can be continuously, the water-soluble component in efficient, the big flow ground collection gaseous contaminant, when separating gaseous state and aerosolized pollutant, can not cause the wet type parallel-plate gaseous diffusion collection tube of interference to gas circuit.
For achieving the above object, the present invention takes following technical scheme: a kind of wet type parallel-plate gaseous diffusion collection tube, it is characterized in that: it comprises the gas trapping plate that two-layer specification is identical, be arranged in parallel, form a slit between the two described gas trapping plates, the bottom of described slit is the gas access, the top of described slit is a gas vent, and the top of two described gas trapping plates is respectively arranged with absorption liquid inlet, and the bottom of two described gas trapping plates is respectively arranged with absorption liquid outlet; On the relative side of two described gas trapping plates, described absorption liquid enters the mouth and adheres to one deck hydrophilic coating respectively between the corresponding described absorption liquid outlet.
