Embodiment Construction
[0033] The present invention will be further described with reference to the accompanying drawings.
[0034] A kind of oil mist collection device of steam turbine main oil tank, such as figure 1 Shown, comprise the main box body 1 that one side has opening, be provided with air inlet pipe 3 on the side of main box body 1 away from opening, be provided with a collection pipe 4 for collecting waste water on main box body 1 lower surface, in A side of the main box 1 close to the opening is provided with a secondary box 2 .
[0035] Such as figure 1 As shown, a first filter screen 13 is installed at the opening of the main box body 1, and the first filter screen 13 is set as a stainless steel filter screen.
[0036] Such as figure 1 As shown, the sub-casing 2 includes a first plate 5, a second plate 6, a third plate 7, and a fourth plate 8, and the first plate 5 is fixedly connected to an end of the upper surface of the main box body 1 near the opening; the second plate 6 is f...

The invention relates to an oil mist impurity removal device, in particular to an oil mist collecting device of a main oil tank of a steam turbine. The oil mist collecting device of the main oil tankof the steam turbine comprises a main box body, an auxiliary box body, a gas inlet pipe and a collecting pipe. The auxiliary box body comprises a first plate, second plates, a third plate and a fourthplate. An air outlet is formed among the fourth plate, the second plates and the third plate, and a first filtering net is installed in an opening of the main box body. Oil mist is filtered by the first filtering net, the filtered oil mist passes through the main box body, passes through the first plate, the second plates, the third plate and the fourth plate and then flows out of the air outlet.The second plates are fixedly connected with the two side of the third plate. The filtered oil mist flows out of the air outlet, and therefore the influence of the wind and the rainwater on the oil mist is avoided. The oil mist flows out of a gas outlet after passing through the fourth plate, the second plates, the first plate and the third plate in sequence, small oil drops in the oil mist condense through resistance of the first plate, the second plates, the third plate and the fourth plate, the condensed oil drops flow into the main box body from the fourth plate, and therefore the effectof condensing collection of the oil mist is improved.
Description
technical field [0001] The invention relates to an oil mist removal device, in particular to an oil mist collection device for a main oil tank of a steam turbine. Background technique [0002] A steam turbine is a rotating power machine that converts the energy of steam into mechanical work. Also known as steam turbine. It is mainly used as a prime mover for power generation, and can also directly drive various pumps, fans, compressors and ship propellers. [0003] The function of the main oil tank of the steam turbine is mainly to collect and distribute the return oil of the lubricating oil from all parts of the steam turbine, and at the same time, the water vapor in the oil and the gas carried in the oil return are discharged out of the workshop through the exhaust fan of the oil tank. The main oil tank is also connected There is an oil purification device to further process the impurities in the oil to ensure the quality of the oil. Start the oil pump, the AC lubricati...
