Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of oil mist separation devices, and in particular to a horizontal vortex oil mist separation device. Background Technology
[0002] Existing separation devices include a central shaft with wind-blocking blades evenly distributed on its circumferential surface. The wind-blocking blades change the direction of airflow and particle movement based on inertia, guiding the particles to settle.
[0003] In theory, after dust particles and airflow pass through the wind deflector blades, their original direct current direction is changed. Under the inertial force of the spiral, the dust particles continue to move backward in the spiral direction and finally fall into the dust collection port at the end.
[0004] However, in the actual separation process, the trajectories of large and small particles are different; for example... Figure 1 As shown, the trajectory of large particles in the separation device 1 is consistent with the theoretical trajectory. After passing the wind deflector, the original direct current direction is changed. Under the inertial force of the spiral, the large particles continue to move backward in the spiral direction and finally fall into the dust collection port 2 at the end.
[0005] like Figure 2 As shown, the trajectory of the fine particles in the separation device 1 differs from the theoretical trajectory. Due to insufficient centrifugal force and the strong turbulence generated by the airflow re-suspending and entraining the fine particles, their trajectory is quite chaotic. The vast majority of fine particles do not fall into the dust collection port 2 but are discharged from the air outlet 3, resulting in low dust separation efficiency and poor dust separation effect. Utility Model Content
[0006] The purpose of this invention is to provide a horizontal vortex oil mist separator, which has the advantage of being able to effectively separate tiny particles, and has a significant effect on separating oil mist, dust and other pollutants.
[0007] To achieve the above and other related objectives, this utility model provides the following technical solution:
[0008] A horizontal vortex oil mist separator includes a housing, a first separation chamber and a second separation chamber communicating with the first separation chamber are provided inside the housing, and an oil outlet is provided at the bottom of both the first separation chamber and the second separation chamber;
[0009] The housing has an air intake on one side that communicates with the first separation chamber, and an air outlet on the other side that communicates with the second separation chamber.
[0010] A first guide cone is fixedly installed inside the first separation chamber; a central shaft is installed inside the second separation chamber, and a spiral blade is fixedly connected to the inner wall of the second separation chamber on the side wall of the central shaft, and guide cones are fixedly installed at both ends of the central shaft.
[0011] In one embodiment of the present invention, the bottom surface of the first guide cone is close to the air inlet side, and the diameter of the bottom surface of the first guide cone is larger than the diameter of the air inlet.
[0012] In one embodiment of the present invention, a plurality of support plates are distributed around the first guide cone, and the plurality of support plates are fixedly connected to the inner wall of the first separation cavity.
[0013] In one embodiment of the present invention, the sidewall of the first separation chamber near the second separation chamber is inclined.
[0014] In one embodiment of the present invention, the sidewall of the second separation chamber near the first separation chamber is inclined.
[0015] In one embodiment of the present invention, a second guide cone is fixedly provided at the end of the central shaft near the first separation chamber, and the bottom surface of the second guide cone is fixedly connected to the central shaft.
[0016] The first guide cone and the second guide cone are coaxially arranged.
[0017] In one embodiment of the present invention, a third flow guide cone is fixedly provided at the end of the central shaft on the side away from the first separation chamber, and the bottom surface of the third flow guide cone is fixedly connected to the central shaft;
[0018] The third guide cone is coaxially arranged with the second guide cone.
[0019] As described above, the horizontal vortex oil mist separator of this utility model has the following beneficial effects:
[0020] 1. The housing is provided with a first separation chamber and a second separation chamber to achieve multi-stage separation of oil mist, dust and other particles, thereby improving the separation effect; a first guide cone is provided in the first separation chamber, which plays a good guiding role for the airflow entering the first separation chamber through the air inlet; the airflow will swirl and collide here, and some large oil particles will fall directly to the bottom of the first separation chamber and be discharged from the oil outlet;
[0021] 2. The second guide cone directs the airflow to the spiral blades. After being dispersed by the spiral blades, the airflow changes to a spiral direction and circulates under the inertial force of the spiral. After passing through the third guide cone, the airflow is accelerated by centrifugal separation. Large particles or large oil particles are separated out under the action of centrifugal force. During the airflow process, the small particles mixed in the airflow continuously collide with the third guide cone. The small particles are detached from the airflow and fall off with the movement of the large particles and are discharged from the oil outlet. This enables the effective separation of small particles. The separation effect of oil mist, dust and other particles is significant and the separation efficiency is improved. Moreover, the multi-stage vortex separator has a simple structure and a small increase in cost. Attached Figure Description

Several support plates 14 are distributed around the first guide cone 11. The support plates 14 are welded and fixed to the inner wall of the first separation chamber 5. The bottom surface of the first guide cone 11 is close to the air inlet 9, and the diameter of the bottom surface of the first guide cone 11 is larger than the diameter of the air inlet 9.
[0033] The first guide cone 11 plays a good guiding role in the airflow entering the first separation chamber 5 through the air intake 9; the airflow will swirl and collide here, and some large oil particles will fall directly to the bottom of the first separation chamber 5 and be discharged from the oil outlet.
[0034] Please see Figure 3 , Figure 4 and Figure 5A central shaft 12 is provided inside the second separation chamber 6, and the central shaft 12 is coaxially arranged with the second separation chamber 6.

Some of the large oil particles fall directly to the bottom of the first separation chamber 5 and are discharged from the oil outlet.
[0037] The second guide cone 15 directs the airflow to the spiral blades 13. After being dispersed by the spiral blades 13, the airflow becomes spiral and flows in a spiral direction. Under the inertial force of the spiral, the airflow circulates and then passes through the third guide cone 16, where centrifugal separation accelerates the movement of the airflow. Large particles or large oil particles are separated out under the action of centrifugal force. During the airflow process, the tiny particles mixed in the airflow continuously collide with the third guide cone 16. The tiny particles will detach from the airflow and fall off with the movement of the large particles and be discharged from the oil outlet.
