At present, filters most on the market filters liquid, only have the filter of minority for gas filtration, and gas is divided into the gas of number of different types, the heavier-than-air gas of such as density and the lighter-than-air gas of density are also different in the design of filter.
The utility model devises a accurate filter for density lighter-than-air gas hydrogen, inverted structure is adopted to be designed a little less than gas outlet by air inlet, hydrogen is entered from air inlet and rises to the top of filter cylinder, thus the original gas in filter cylinder to be pressed down and blowoff valve through the bottom of filter cylinder is discharged, filter core is located at filter cylinder top, when filling hydrogen in filter cylinder, hydrogen can be extruded and enter filter core by the upper face plate at top, by the filtration of filter core, the hydrogen filtered in each filter core is collected by the gas skirt of the funnel type be located at bottom filter core by clean hydrogen, and discharged by gas outlet, the design of inverted filter core and filtration, the hydrogen making density be less than air assembles at filter cylinder top and pressurized enters upper face plate structure, density can start to be extruded to below filter cylinder higher than the gas of air, and then the purity of the hydrogen of guarantee metre filter.In addition, filter cylinder of the present utility model adopts two flap-type can opening-closing structure, and convenient disassembly, is convenient to clean and maintenance.
Summary of the invention
For above-mentioned situation, the utility model provides a kind of accurate filter, inverted structure is adopted to be designed a little less than gas outlet by air inlet, hydrogen is entered from air inlet and rises to the top of filter cylinder, thus the original gas in filter cylinder to be pressed down and blowoff valve through the bottom of filter cylinder is discharged, filter core is located at filter cylinder top, when filling hydrogen in filter cylinder, hydrogen can be extruded and enter filter core by the upper face plate at top, by the filtration of filter core, the hydrogen filtered in each filter core is collected by the gas skirt of the funnel type be located at bottom filter core by clean hydrogen, and discharged by gas outlet, the design of inverted filter core and filtration, the hydrogen making density be less than air assembles at filter cylinder top and pressurized enters upper face plate structure, density can start to be extruded to below filter cylinder higher than the gas of air, and then the purity of the hydrogen of guarantee metre filter.In addition, filter cylinder of the present utility model adopts two flap-type can opening-closing structure, and convenient disassembly, is convenient to clean and maintenance.
To achieve these goals, the technical solution of the utility model is as follows:
Accurate filter, comprise filter cylinder, air inlet, gas outlet, blowoff valve, safety valve root valve adpting flange, it is characterized in that, also comprise upper face plate, some Columned filter cores, funnel type gas skirt, filter cylinder one side-lower is provided with air inlet, opposite side is provided with gas outlet, air inlet stretches in filter cylinder, gas outlet is connected by seal for pipe joints with the bottom of funnel type gas skirt, the top of described funnel type gas skirt is provided with the gas collection hole corresponding to the quantity of Columned filter core, upper face plate is also provided with the pneumatic trough corresponding to funnel type gas skirt position, funnel type gas skirt is extend into inner bottom each Columned filter core, Columned filter core top is fixedly mounted in the pneumatic trough of upper face plate.
The level height of described air inlet is lower than gas outlet level height.
Described filter cylinder is that two flap-type can opening-closing structure, by middle road Flange joint between two filter cylinders.
At least one support bar is also provided with between described upper face plate and funnel type gas skirt.
