Description
Technical field
The utility model relates to a kind of gas-filtering device, in particular to a kind of good airproof performance, it is etch-proof be used for chemical industry
The gas-filtering device of production.
Background technique
In Chemical Manufacture, it is often necessary to be filtered to gas, to go to clean when gas enters next process
Matter.But chemical gases have corrosivity mostly, are easy to cause to corrode to the container or pipeline of filtering, and reduce component uses the longevity
Life.Meanwhile existing filter device usually only has an air inlet and a gas outlet, gas can only be discharged from a direction
Body.And after filtering agent failure, the replacement of filtering agent is also inconvenient.
Polytetrafluoroethylene (PTFE) is commonly called as " King ", is the high-molecular compound as made of tetrafluoroethylene polymerization, has excellent
Chemical stability, sealing property, high lubrication, non-stickiness, electrical insulation and good anti-aging endurance.
Summary of the invention
In order to solve above-mentioned deficiency in the prior art, the utility model provides a kind of filtering agent replacement convenience, corrosion resistant
The gas-filtering device for Chemical Manufacture of erosion.
A kind of gas-filtering device for Chemical Manufacture, including device outer tube and device inner tube；Described device inner tube packet
Include tube body, air inlet and inner tube lid；The tube body is provided with filtering agent；Described device inner tube both ends are equipped with water proof air-permeable layer；Institute
Stating device outer tube includes air inlet, outer tube lid and several gas outlets being located on outer tube tube body.
Further, the used material of the gas-filtering device is polytetrafluoroethylene (PTFE).
Further, said inner tube is covered equipped with several perforation.
Further, screw thread, described device inner tube and described device outer tube are equipped at the inner tube air inlet of described device inner tube
It is connected through a screw thread.
Further, described device outer tube and described device inner tube junction are equipped with sealing ring.
Further, described device outer tube and outer tube lid junction are equipped with sealing ring.
When the utility model is used, will be needed being screwed in the device inner tube charging apparatus inner tube equipped with filtering agent
The gas of filter is passed through from air inlet, and gas is entered in the filtering agent in device inner tube by air inlet, by the gas of filtering agent
Body is overflowed from the perforation that inner tube covers again, is entered between device inner tube and device outer tube, if from doing on device outer tube
It is overflowed in port.
When filtering agent failure needs replacing, device inner tube need to only be screwed out from device outer tube, be replaced in the device of core
Pipe.
The utility model has the beneficial effects that (1) device uses polytetrafluoroethylene (PTFE) material, the corrosion of chemical mediator is avoided；
(2) tube body is longer, guarantees coming into full contact with for gas and filtering agent；(3) multiple gas outlets are defeated from all directions by the gas of output
Out；It is convenient and safe to replace filtering agent.
Detailed description of the invention
