Description
Technical field
This utility model relates to a kind of scalable gas sampling cover.
Background technology
Gas skirt is the collection device of flue gas purification system polluter, dust and gaseous contamination source can be imported cleaning system, prevent it to workshop and Atmospheric Diffusion simultaneously, pollute.Its performance has directly impact to the technical-economic index of cleaning system.Owing to the form of polluter device structure and the difference of production operation technique, gas skirt is diversified.Partly or wholly enclosing polluter, keeps certain negative pressure in cover, can prevent any diffusion of pollutant.
Current existing laboratory exhaust gas collecting hood locations of structures is fixed, regulation inconvenience, causes gas sampling poor effect.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in construction, the position of convenient regulation gas hood and angle, keeps easy to use, the scalable gas sampling cover that gas sampling is effective.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of scalable gas sampling cover, including gas hood, the first trachea, the second trachea and exhaustor, it is provided with arc groove inside described gas hood, described first trachea two ends are provided with the first trachea cover, described second trachea two ends are provided with the second trachea cover, the 3rd trachea cover it is provided with bottom described exhaustor, first trachea cover of described first trachea lower end is flexibly connected with gas hood, first trachea cover of described first trachea upper end and the second trachea cover of the second trachea lower end are flexibly connected, and the second trachea cover of described second trachea upper end and the 3rd trachea cover are flexibly connected.
As preferably, described first trachea cover, the second trachea cover and the 3rd the most hemispherical setting of trachea cover, keep easy installation and reliable.
As preferably, the rounded array distribution of described arc groove, arc groove enables to flow rotation.
As preferably, being provided with rubber ring bottom described gas hood, rubber ring can protect gas hood, prevents gas hood from deformation of colliding with occur.
As preferably, described gas hood is connected with rubber ring gluing, keeps compact conformation.
The beneficial effects of the utility model are: the first trachea of setting, the second trachea and exhaustor use and be flexibly connected, the position of convenient regulation gas hood and angle, keep easy to use；It is provided with arc groove inside the gas hood arranged and enables to produce swirling eddy during air-breathing so that gas sampling is effective.
Accompanying drawing explanation
Fig. 1 is the structure chart of this utility model a kind of scalable gas sampling cover.
Fig. 2 is the gas hood cut-away view of this utility model a kind of scalable gas sampling cover.
