Description
Technical Field
The utility model relates to the technical field of turbine oil systems, in particular to a fire prevention mechanism and a fire prevention system for a turbine oil system.
Background
The turbine oil system is a necessary auxiliary system for the operation of a turbine of a power plant, and is used for lubricating each bearing of a turbine shafting, regulating speed, controlling hydraulic pressure, participating in interlocking protection, jigger lubrication and the like. The main equipment materials comprise oil pipelines, oil tanks, valves, oil pumps, control clamping pieces, modules, sealing piece auxiliary materials and the like, and an operation layer at the position is crossed with high-temperature pipelines such as a main steam pipeline, a reheat steam pipeline, a steam extraction regenerative pipeline and the like, and cannot be completely separated due to process arrangement. The turbine lubricating oil is combustible liquid, and has flash point of 180-200 deg.c, ignition point of 240 deg.c and self-ignition point of 300-350 deg.c, so that it is easy to catch fire in open fire and in high outside temperature.
Disclosure of Invention
The utility model aims to: in order to overcome the defects of the background art, a first object of the utility model is to disclose a fire protection mechanism of a turbine oil system;
a second object is to disclose a turbine oil system comprising a fire protection mechanism as described above.
The technical scheme is as follows: the utility model discloses a fire prevention mechanism of a turbine oil system, which comprises a main oil tank, a turbine and a boiler, wherein the main oil tank stores lubricating oil, oil circulation is established between the main oil tank and the turbine through a lubricating oil inlet and outlet oil pipe, the boiler is connected with the turbine through a main steam pipe, a main steam valve is arranged on the main steam pipe, and a main oil tank partition is arranged between the joint of the main oil tank and the oil pipe and the main steam pipe.
The pipeline, flange and valve of the main oil tank are prevented from splashing to the high-temperature steam pipeline when lubricating oil leaks, and flash point is reached to catch fire.
Furthermore, the main steam valve is totally closed through the main steam valve partition, and when the turbine oil system leaks, lubrication cannot splash on the main steam valve (a high-temperature heat source, and the steam temperature reaches more than 500 degrees), so that the flash point is reached, and fire is caused.
Furthermore, the main oil tank partition and the main steam valve partition are transparent high-temperature resistant partition plates.
A turbine oil system comprises the turbine oil system fireproof mechanism.
The beneficial effects are that: compared with the prior art, the utility model has the advantages that: the main ignition source of the turbine oil system can be effectively isolated from a high-temperature heat source or an open flame, so that fire accidents are prevented; the transparent high-temperature resistant material is adopted, so that production operators can conveniently inspect and observe, fireproof measures are taken into account, and normal production operation is not influenced.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model.
Detailed Description
The turbine oil system as shown in fig. 1 comprises a main oil tank 1, a turbine 2 and a boiler 3, wherein the main oil tank 1 stores lubricating oil, oil circulation is established with the turbine 2 through a lubricating oil inlet and outlet oil pipe 4, the boiler 3 is connected with the turbine 2 through a main steam pipeline 5, and a main steam valve 6 is arranged on the main steam pipeline 5.
The lubricating system is relatively concentrated in the turbine operating platform and the steam pipeline interlayer and is closely abutted against high-temperature steam (the medium temperature is above 500 ℃), which is influenced by the process requirements of equipment. The turbine lubricating oil is combustible liquid, and has flash point of 180-200 deg.c, ignition point of 240 deg.c and self-ignition point of 300-350 deg.c, so that it is easy to catch fire in open fire and in high outside temperature. This patent cuts off through arranging below, can effectively keep apart the main oil tank of high temperature medium or main oil storage, and the risk of catching fire is reduced to the maximum probability.
The design of the patent comprises that a main oil tank partition 7 is arranged between the main oil tank 1 and the connection part of the oil pipe and a main steam pipeline 5, so that when lubricating oil leakage occurs in the pipeline, the flange and the valve of the main oil tank, the lubricating oil is prevented from splashing on a high-temperature steam pipeline, and the flash point is reached to catch fire; the main steam valve 6 is fully sealed through the main steam valve partition 8, and when a turbine oil system leaks, lubrication cannot splash to the main steam valve (a high-temperature heat source, and the steam temperature reaches more than 500 degrees), and the flash point is reached to catch fire.
The main oil tank partition 7 and the main steam valve partition 8 are transparent high-temperature resistant partition boards, and can adopt stainless steel frames and transparent temperature resistant materials, so that production operation personnel can conveniently inspect and observe.
