Description

Technical Field

[0001] The utility model belongs to the technical field of oil mist separation, and particularly relates to a vertical oil mist separation and collection device. Background Art

[0002] Oil mist is generated during the drying process of the separation generator stator, and oil mist is also generated during the pressure relief and vacuuming process of the separation VPI paint tank. With the continuous improvement of environmental awareness, more and more manufacturing companies choose waste gas treatment equipment to efficiently purify waste gas and make its emissions more environmentally friendly. As a common device for waste gas treatment equipment in the prior art, the oil mist separation device has the following disadvantages: the separator is fixed inside the collection box and is not easy to disassemble, resulting in high maintenance and cleaning costs for subsequent equipment. Utility Model Content

[0003] The utility model aims to provide a vertical oil mist separation and collection device, which can improve the convenience of equipment installation and maintenance.

DETAILED DESCRIPTION Embodiment 1

[0017] like Figure 1 and 2As shown, a vertical oil mist separation and collection device comprises a collection box 1, an oil collecting funnel 2 is arranged at the bottom of the collection box 1, an air inlet 201 is arranged on the side of the oil collecting funnel 2, an oil discharge port 202 is arranged at the bottom, a collection tank 3 is arranged below the oil discharge port 202, an air outlet 101 is arranged at the top of the collection box 1, and a plurality of mounting ports 102 are arranged around, and a separator 4 is detachably arranged corresponding to each mounting port 102, and the separator 4 comprises a mounting plate 401, a handle 402 and a baffle arranged at an angle of α=50° with the mounting plate 401. Plate 403, a support plate 404 is arranged between the mounting plate 401 and the baffle 403, a plurality of baffles 403 divide the inner cavity of the collecting box 1 in a cross-distributed manner to form a labyrinth-like ventilation path, and the handle 402 is arranged on the side of the mounting plate 401 away from the baffle 403; the mounting port 102 includes an outwardly protruding mounting strip 103, the mounting strip 103 is provided with a mounting hole, the mounting plate 401 is provided with a through hole corresponding to the mounting hole, and a fastener is arranged in the through hole; this embodiment is suitable for separating the oil mist generated during the drying process of the generator stator. Embodiment 2

[0018] The difference between this embodiment and the first embodiment is that: α=45°; the separator 4 also includes a guide plate 405, which is integrally connected to the lowest part of the baffle 403 and the plane on which it is located is parallel to the vertical direction, so as to prevent the falling oil droplets from being driven upward by the rising airflow; the collecting box 1 is supported on the ground by four columns 5; a ball ring packing layer 6 is provided between the installation port 102 located at the top and the air outlet 101 to further filter the oil mist in the exhaust gas and improve the oil mist removal rate; the inner wall of the collecting box 1, the inner wall of the oil collecting funnel 2 and the outer surface of the baffle 403 are sprayed with Teflon coating, because the Teflon coating has extremely strong non-stickiness, almost all substances do not adhere to the Teflon coating, so that the oil mist will not stick to the inside of the equipment, and it is resistant to high temperature and corrosion, and can extend the service life of the equipment; this embodiment is suitable for the oil mist generated during the pressure relief and vacuum extraction process of the VPI paint dipping tank. The device keeps the airflow unobstructed and will not cause the gas to be enriched in the VPI paint dipping tank, and there is no safety hazard.

[0019] When the utility model is in use, organic waste gas enters the interior of the equipment through the air inlet 201, and is then discharged from the air outlet 101 through a labyrinth ventilation path. In this process, when the gas passes through the baffle 403 at a certain speed, since the mass of the oil mist is heavier than that of the waste gas, under the action of inertia, the oil mist collides with the baffle 403 and adheres to the surface of the baffle 403. The gas changes direction and is discharged from the air outlet 101 after passing through the ball ring packing layer 6. The diffusion of the oil mist on the surface of the baffle 403 and the gravity sedimentation of the oil mist cause the small droplets to form larger droplets, which flow down along the baffle 403 and the guide plate 405, and finally flow into the collection tank 3 below along the oil collecting funnel 2. The advantages of the utility model are as follows: the ball ring is a polymer material with the property of not being oil-sticky, and because of the openings in the ring wall, the utilization rate of the inner space and the inner surface of the ring is greatly improved, the air flow resistance is small, the liquid is evenly distributed, and it has the advantages of large flux, small resistance, high separation efficiency and large operational flexibility. A ball ring filler is added behind the baffle to further filter the oil mist in the exhaust gas, thereby improving the oil mist removal rate; when installing the separator 4, it is only necessary to align the through hole with the mounting hole and use fasteners to connect them to achieve rapid assembly. This design is conducive to standardized production and can reduce maintenance costs.

[0020] The present utility model is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present utility model, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present utility model.
