Description
[technical field]
The utility model relates to the steam turbine set, and more particularly, the nothing that relates to a kind of steam turbine unit is leaked device for exhausting oily smoke.
[background technique]
At present; The oil extraction blower fan is generally common centrifugal fan in traditional device for exhausting oily smoke; There are defectives such as draft deficiency or draft be excessive; It is untimely that the draft deficiency is separated oil smoke, causes a series of problems such as oil mixed with water, turbine oil emulsification, pipeline corrosion and regulating element be malfunctioning, the safety in production of serious threat unit; Draft is excessive, causes a large amount of turbine oils not to be drawn out of by timely separation, causes band oil in the cigarette, and influence is carried out production strictly in line with rules and regulations.And the oil extraction blower fan is a horizontal type structure in the device for exhausting oily smoke, and is poorly sealed between impeller shaft and spiral case, is prone to cause leakage of oil, and the long-pending oil in spiral case bottom is serious.
Smoke exhaust fan only is installed on the main fuel tank in the tradition device for exhausting oily smoke, causes operation under positive pressure in the bearing housing easily, and the oil catch leakage of oil is serious, pollutes the scene, has disaster hidden-trouble, and gland packing leakage condenses into water in return line, can't thoroughly obtain separating.The defective value of said existing technology must improve.
[model utility content]
The purpose of the utility model is to above-mentioned technological deficiency, provides a kind of nothing to leak device for exhausting oily smoke, and this a kind of nothing is leaked device for exhausting oily smoke compact structure, efficient, is fit to the discharge equipment of thermal power plant different capacity unit (comprising main and auxiliaries).
The technological scheme of the utility model is described below: a kind of nothing is leaked device for exhausting oily smoke; Comprise support one, oil exit pipe, second-stage separator, smoke exhaust fan, primary separator, flange one, air door, flange two, support two, it is characterized in that said second-stage separator is located on the support one; Said oil exit pipe is located at the second-stage separator lower end; Said smoke exhaust fan is connected with second-stage separator, and said primary separator and smoke exhaust fan be vertical to be connected and to be located on the support two, and said flange one is located at the primary separator below and is attached thereto; Said air door is located at flange one below and is attached thereto, and said flange two is provided with the air door below and is attached thereto.
According to the utility model of said structure, its characteristic also is, is folded with sealing gasket one between said smoke exhaust fan and the primary separator.
According to the utility model of said structure, its characteristic is that also said smoke exhaust fan is connected through bolt with primary separator.
According to the utility model of said structure, its characteristic also is, is folded with sealing gasket two between said flange one and the air door.
According to the utility model of said structure, its characteristic is that also said flange one is connected through bolt with air door.
According to the utility model of said structure, its beneficial effect is that the utility model adopts vertical structure, and good seal does not have and leaks; Fan efficiency is high, and is safe and reliable; Three grades of separation structures can thoroughly separate oil smoke; It is adjustable to exert oneself, easy for installation, simple in structure.
