Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The utility model relates to a lubricating oil fume treatment device for a power plant, which is structurally shown in figure 1 and comprises a smoke exhaust pipeline 2 connected with an engine oil tank 1, wherein the other end of the smoke exhaust pipeline is divided into a smoke exhaust pipe branch 3 and a smoke exhaust pipe main path 4, the other end of the smoke exhaust pipe main path 4 is connected with a silencer 9 and a blower 5 in parallel, the outlet of the blower 5 is connected with an air preheater 6 through a pipeline, and the outlet of the air preheater 6 is connected with a secondary air box of a hearth 8 through a secondary air duct 7.
A branch electric valve 24 is arranged on the branch 3 of the smoke exhaust pipe.
The front and back both sides of the machine oil tank 1 are respectively provided with a smoke exhaust fan 10, the two smoke exhaust fans 10 are jointly connected with a three-way valve 11 through a pipeline, and the other end of the three-way valve 11 is connected with a smoke exhaust pipeline 2.
And manual valves 12 are arranged on pipelines between the two smoke exhaust fans 10 and the three-way valve 11.
The outlet of the blower 5 is provided with a blower outlet baffle 13, and the outlet of the air preheater 6 is provided with an air preheater outlet baffle 14.
And a main path electric valve 15 is also arranged at one end of the main path 4 of the smoke exhaust pipe close to the smoke exhaust pipeline 2.
The main smoke exhaust pipe path 4 is also connected with a condensed water discharge pipe 16, and the condensed water discharge pipe 16 is provided with a water drain valve 17.
An air preheater a19, a blower a20 and a silencer a21 are sequentially connected to the secondary air box of the furnace 8 through a secondary air duct a18, and an air preheater outlet baffle a22 and a blower outlet baffle a23 are respectively arranged at the outlets of the air preheater a19 and the blower a 20.
