Description

Technical Field

[0001] The utility model relates to the technical field of vertical pipeline oil mist separators, in particular to a vertical pipeline oil mist separator with multi-stage baffle filtering and separation functions. Background Art

[0002] In the working conditions of centralized lubrication oil stations for steam turbines or similar oil stations such as fans and motors, it is required to maintain a certain negative pressure inside the oil tank to prevent the internal air from flowing out to prevent oil and gas from polluting the environment. This requirement is generally achieved by using a fan to pump the air above the oil tank, and then centrally treat the air containing oil and gas after it is extracted. In the process of the fan pumping oil and gas, in order to separate and purify the oil and gas, it is necessary to install an oil mist separator in front of the fan inlet to efficiently separate the oil and gas. The oil mist separator is a device used to separate oil mist or suspended particles in a liquid. It is usually used in industrial production processes and can effectively separate oil mist from gas or liquid to protect equipment and the environment. However, most vertical pipeline oil mist separators are often simple in structure and have limited filtering effects, which still pollute the environment. Utility Model Content

[0003] In order to overcome the problem that most vertical pipeline oil mist separators only perform filtering treatment once, the structure is often simple, resulting in limited oil mist filtering and separation effects, which will eventually cause some environmental pollution.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the traditional vertical pipeline oil mist separator, most of them use filter elements for oil mist filtration and separation. Most of the structures are relatively simple, and often only one filtration process is performed, resulting in limited oil mist filtration and separation effects, which will eventually lead to environmental pollution. The multi-stage filtration and separation method can ensure the filtration and separation effect, make the overall structure compact, small in size, and low in cost, thereby enhancing the practical value of the separator;

[0014] 2. When filtering oil mist in multiple stages, the oil mist enters the stainless steel wire mesh from the bottom of the filter cartridge. The filtered oil mist passes through the filter holes and enters the primary oil return tank. Most of the oil particles gather into lubricating oil and return to the oil tank through the primary oil return pipe. The remaining oil smoke enters the winding glass fiber mesh through the filter holes. The winding glass fiber mesh is used to further filter the oil mist, so that large oil particles fall into the primary oil return tank and return to the oil tank through the primary oil return pipe. Another part of the oil mist enters the secondary oil return tank. The large oil particles gather and fall in the secondary oil return tank and are discharged back to the oil tank through the secondary oil return pipe. This solves the problem that the filtering effect of most vertical pipeline oil mist separators is relatively limited, which still causes environmental pollution and ensures the filtering effect of the separator;

[0015] 3. When fixing the position of the oil mist separator, the upper flange fixes one end of the outer cylinder, and the lower flange fixes the other end of the outer cylinder, and the separator is stably fixed to the air inlet of the fan. The filter cartridge is fixed by the fixing plate, and the stainless steel fine wire mesh is fixed by the first positioning bar. The wound glass fiber mesh is fixed by the second positioning bar, and the stainless steel fine wire mesh and the wound glass fiber mesh are separated by a partition. After multi-stage filtration treatment, air with less oil content is obtained. Finally, this part of the air is further finely filtered through the oil mist filter element and discharged.
