In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of waste gas filter, comprise reflux cylinder, atomization box, gas-liquid mixed runner and mist guide tube, and described atomization box is rectangular structure, and the atomization box upper surface is fixed with reflux cylinder and mist guide tube; Described gas-liquid mixed runner is fixed in and refluxes between cylinder and mist guide tube; Described side of refluxing cylinder is fixed with the drop collecter ring, and the end face of the cylinder that refluxes has exhaust vent.
Further, an end of described gas-liquid mixed runner is fixed in the side of the cylinder that refluxes, and the bottom surface of gas-liquid mixed runner is connected with the top of mist guide tube, and the other end of gas-liquid mixed runner has waste gas inlet.
Further, the bottom surface in described atomization box is equipped with atomization transducer.
Further, described atomization transducer is ultrasonic atomization transducer.
Further, described backflow cylinder is set with the O RunddichtringO with the bearing of atomization box.
Further, the bearing of described mist guide tube and atomization box is set with the O RunddichtringO.
Further, the metal sintering filter that described drop collecter ring is multilayer or the metal filter screen of multilayer.
A kind of waste gas filter of the utility model, having solved traditional filter core easily stops up, affect the Instrumental Analysis precision, and the problem that human body is damaged, the water filtration mode that argon gas waste gas is mixed with water droplets, have good purification, the simple outstanding advantages that waits of cleaning, and avoided the saturated blockage problem of conventional filtration core, made to drop to minimum to the injury of human body.
The accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms the part of specification, with embodiment mono-of the present utility model, is used from explanation the utility model, does not form restriction of the present utility model.In the accompanying drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic top plan view of the present utility model;
Fig. 3 is that the A of Fig. 2 is to the planing surface schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
A kind of waste gas filter, comprise the cylinder 1 that refluxes, atomization box 2, gas-liquid mixed runner 4 and mist guide tube 10 as shown in Figure 1, Figure 2, Figure 3 shows, and described atomization box 2 is rectangular structure, and atomization box 2 upper surfaces are fixed with reflux cylinder 1 and mist guide tube 10; Described gas-liquid mixed runner 4 is fixed in and refluxes between cylinder 1 and mist guide tube 10; Described side of refluxing cylinder 1 is fixed with drop collecter ring 5, and the end face of the cylinder 1 that refluxes has exhaust vent 6; , an end of described gas-liquid mixed runner 4 is fixed in the side of the cylinder 1 that refluxes, and the bottom surface of gas-liquid mixed runner 4 is connected with the top of mist guide tube 10, and the other end of gas-liquid mixed runner 4 has waste gas inlet 3; Bottom surface in described atomization box 2 is equipped with atomization transducer 7; Described atomization transducer 7 is ultrasonic atomization transducer; The described cylinder 1 that refluxes is set with the O RunddichtringO with the bearing of atomization box 2; Described mist guide tube 10 is set with the O RunddichtringO with the bearing of atomization box 2; The metal sintering filter that described drop collecter ring 5 is multilayer or the metal filter screen of multilayer.
