Problems solved by technology
[0002] Gas filters are widely used in the collection system of gas analysis instruments. The main structure is that the filter cup is installed on the base, the air inlet and the gas outlet are all opened to the inside of the filter cup, and a filter element is arranged in the filter cup. The prior art The filter elements in the filter mostly use microporous ceramics or filter paper, and the filtering effect is not ideal, especially only part of the dust can be filtered out, and the moisture in the gas cannot be removed.

Embodiment Construction
[0013] Such as figure 1 As shown, the present invention includes a tank body 1, a front cover 2, and a rear cover 4. The front end of the front cover 2 is provided with an air inlet 3, and the rear cover 4 is provided with an air outlet 5. The inside of the tank body 1 is close to the front cover. 2 and the back cover 4 are provided with a composite multi-layer microporous hydrophobic membrane, the middle of the tank body 1 is provided with a microporous ceramic layer 8 and a microporous filter layer 9, and the composite multi-layer microporous hydrophobic membrane is composed of a microporous hydrophobic Membranes 6 and high-density sponges 7 are arranged alternately, and the microporous filter layer 9 is made of microporous plastic. The double-layer composite multi-layer microporous hydrophobic membrane can remove moisture more effectively, and is suitable for gas filtration with high moisture content.

A provided gas water-filter dust-filter apparatus comprises a tank body, a front cover and a rear cover; the front end of the front cover is provided with a gas inlet, and the rear cover is provided with a gas outlet; positions, close to the front cover and the rear cover, in the tank body are both provided with composite multilayer micropore hydrophobic membranes; and the center of the tank body is provided with a micropore ceramic layer and a micropore filtering layer. The beneficial effects comprise that the gas water-filtering dust-filtering apparatus is simple in structure, the double-layer composite multilayer micropore hydrophobic membranes help to fully remove moisture in a gas, through the combined usage of the micropore filtering layer and the micropore cermic layer, dust is relatively effectively removed; and the apparatus has the advantages of removing moisture in the gas, and the like, besides the apparatus is capable of filtering out dust.
Description
technical field [0001] The invention belongs to the field of gas filtration, in particular to a gas water filter and dust filter. Background technique [0002] Gas filters are widely used in the collection system of gas analysis instruments. The main structure is that the filter cup is installed on the base, the air inlet and the gas outlet are all opened to the inside of the filter cup, and a filter element is arranged in the filter cup. The prior art Most of the filter elements in the filter are microporous ceramics or filter paper, and the filtering effect is not ideal, especially only part of the dust can be filtered out, and the moisture in the gas cannot be removed. Contents of the invention [0003] The problem to be solved by the present invention is to provide a gas water filter and dust filter, which can especially remove moisture in the gas while filtering the dust, and at the same time enhance the filtering effect on the dust. [0004] In order to solve the ab...
