Abstract
The utility model relates to a gas filter. The utility model has the structure that a filter core is arranged between a gas inlet and a gas outlet in a filter cup, when gas passes through the filter core, dust is filtered out. The utility model is characterized in that the gas filter is additionally provided with a layer of micro-hole water discharging film, when the gas passes through the micro-hole water discharging film, water is blocked outside the film so that water content in the gas of the gas outlet is greatly reduced, and in addition, the original filter core can be changed into a micro-hole filtering pipe sleeve so that the dust filtering effect can be improved. The utility model can be used for sampling systems of gas analyzing apparatuses.
Description
The utility model relates to a kind of pneumatic filter.
In the sampling system of gas analysis instrument, be extensive use of pneumatic filter, its structure is that filter bowl is installed on the base, and air inlet pipe, escape pipe are provided with filter core all to the filter bowl inner opening between the air inlet/outlet in filter bowl, when gas passed through filter core, dust was filtered.The filter core of prior art adopts micropore ceramics or filter paper more, and its filter effect is not ideal enough, particularly can only filter the part dust, can't remove the moisture in the gas.
For overcoming above-mentioned shortcoming, task of the present utility model provides a kind of filter of new construction, and it can remove the moisture in the gas when filtering dust, strengthen the filter effect to dust simultaneously.
The technical solution of the utility model is on the basis of conventional filter, set up one deck microporous hydrophobic membrane, that is: filter bowl is installed on the base, and air inlet pipe, escape pipe are all to the filter bowl inner opening, be provided with filter core between the inlet, outlet in the filter bowl, on filter core, have additional microporous hydrophobic membrane.This hydrophobic membrane can clad the outside at filter core; Also can overlay on the inner surface of filter core.When gas passed through, moisture was blocked in outside the film, and moisture greatly reduces in the gas of gas outlet, in addition, original filter core can be changed into a microfiltration tube of being made by cellular plastic, can improve the effect that dust filters.
The utility model has improved filter cartridge construction, has set up water blocking layer, has used microfiltration tube, makes to leach moisture minimizing in the gas, and gas is cleaner.
Now further specify with embodiment in conjunction with the accompanying drawings.
Fig. 1 is the design's a schematic diagram.
Embodiment 1: with reference to Fig. 1, air inlet pipe 12 and escape pipe 13 are arranged on the loam cake 1.Filter bowl 9 usefulness screw sockets 4 are fixed on the loam cake 1.2 is sealing ring.On filter core intubate 6 filter core is installed, the outside is surrounded by hydrophobic membrane 11.3 is silicone rubber tube among the figure, and 5 is set bolt, and 7 is hold-down nut, and 8 is link plate, and 10 is filter core.
