For the defective that exists in the above-mentioned prior art, it is high that technical problem to be solved in the utility model provides a kind of filter efficiency, and the large capillary type oil mist filter of air-treatment amount.
In order to solve the problems of the technologies described above, a kind of capillary type oil mist filter provided by the utility model is characterized in that: comprise framework, upper collecting chamber, lower header, oil collector;
Described upper collecting chamber, lower header are enclosed housing, described oil collector is the oil groove of a single face upward opening, described upper collecting chamber is fixed on the framework upper end, described lower header and oil collector all are fixed on the framework lower end, and lower header be positioned at oil collector directly over, in the same level face, the orthographic projection of lower header is contained within the orthographic projection of oil collector notch;
Described upper collecting chamber is communicated with lower header through many capillaries, and each capillary is straight tube and is parallel to each other, and the capillary array of many rows left and right sides multiple row left ventilation space between each capillary before and after each capillary array became;
Described oil collector is provided with an oil exit pipe, and described lower header is provided with a water inlet pipe, and described upper collecting chamber is provided with an outlet pipe.
Further, the outlet pipe of described upper collecting chamber is provided with an air bleeding valve.
Further, in the capillary array, the adjacent intercapillary spacing in per two left and right sides among the same row is 0.6～0.9 times capillary diameter, and the spacing between the adjacent row is 1～2 times capillary diameter.
Further, in the capillary array, each capillary of each row and each capillary of adjacent row stagger from left to right mutually.
The capillary type oil mist filter that the utility model provides, utilize the low-temp radiating space that forms after the capillary array cooling, make airborne mist of oil condensation separation, and catch condensed mist of oil or oil droplet by capillary array interception, can filter out efficiently the mist of oil that mixes in the air, and the air-treatment amount is also larger, and cost is also lower, can improve working environment.

Fig. 2 is the top view of the capillary array in the capillary type oil mist filter of the utility model embodiment.
The specific embodiment
Below in conjunction with description of drawings embodiment of the present utility model is described in further detail, but present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof all should be listed protection domain of the present utility model in.
Such as Fig. 1-shown in Figure 2, a kind of capillary type oil mist filter that the utility model embodiment provides is characterized in that: comprise framework 1, upper collecting chamber 4, lower header 2, oil collector 3;
Described upper collecting chamber 4, lower header 2 are enclosed housing, described oil collector 3 is oil grooves of a single face upward opening, described upper collecting chamber 4 is fixed on framework 1 upper end, described lower header 2 and oil collector 3 all are fixed on framework 1 lower end, and lower header 2 be positioned at oil collector 3 directly over, in the same level face, the orthographic projection of lower header is contained within the orthographic projection of oil collector notch;
Described upper collecting chamber 4 is communicated with lower header 2 through many capillaries 6, and each capillary 6 is straight tube and is parallel to each other, and the capillary array of many rows left and right sides multiple row left ventilation space between each capillary 6 before and after each capillary 6 was arranged in;
Described oil collector 3 is provided with an oil exit pipe 31, and described lower header 2 is provided with a water inlet pipe 21, and described upper collecting chamber 4 is provided with an outlet pipe 41, and the outlet pipe 41 of upper collecting chamber 4 is provided with an air bleeding valve 7.
Among the utility model embodiment, described capillary is that diameter is the PPR(atactic copolymerized polypropene of 4～5mm) pipe, wall thickness capillaceous is 0.5～1.2mm, the adjacent intercapillary spacing in per two left and right sides among the same row is 0.6～0.9 times capillary diameter, spacing in the capillary array between the adjacent row is 1～2 times capillary diameter, and each capillary of each row and each capillary of adjacent row stagger from left to right mutually.
