Description
Technical Field
The utility model relates to a flue gas recovery unit, especially a simple structure is reliable, design benefit, energy-concerving and environment-protective device of retrieving thermal power plant's lubricating oil system smoke exhausting fan flue gas.
Background
The lubricating oil system of thermal power plant need be constantly to the exhaust flue gas in the atmosphere at the during operation, contains a large amount of lubricating oil in these flue gases, directly discharges and can cause air pollution in the atmosphere to these lubricating oil originally can recycle, and direct discharge has caused very big waste.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a simple structure is reliable, design benefit, energy-concerving and environment-protective's recovery thermal power plant lubricating oil system smoke exhausting fan flue gas's device.
Realize the utility model discloses a retrieve device of thermal power plant's lubricating oil system smoke exhaust fan flue gas, including installing the condenser in the sump, be provided with a low level oil tank in the condenser, the bottom left side of low level oil tank exports through a back flow connection main oil tank smoke exhaust fan, the top of low level oil tank exports through a No. two back flow connection little machine oil tank smoke exhaust fan, a board-like oil filter of defeated oil pipe connection of installing the oil delivery valve door is passed through in the middle part left side of low level oil tank.
The plate type oil filter is connected with a clean oil tank through an oil collecting pipeline provided with an oil collecting valve.
The bottom of the low-level oil tank is also provided with a low-level oil tank blow-off pipe, and a blow-off valve is arranged on the low-level oil tank blow-off pipe.
According to the device for recycling the smoke of the smoke exhaust fan of the lubricating oil system of the thermal power plant, the first return pipe and the second return pipe respectively collect and return smoke recycled from the smoke exhaust fan outlet of the main oil tank and the smoke exhaust fan outlet of the small oil tank into the low-level oil tank in the condenser, the low-level oil tank is used for precipitating and oil-gas gravity separation, after the oil at the lower part reaches a certain height, an oil conveying valve is opened, the oil enters a plate type oil filter from an oil conveying pipe and is filtered and purified by the plate type oil filter, after the filtering and purifying are finished, an oil collecting valve is opened, and the purified oil is conveyed into a clean oil tank; when the oil stain at the bottom of the low-level oil tank is excessive, the drain valve is opened, and the oil stain is discharged through the drain pipe of the low-level oil tank.
This patent retrieve device of thermal power plant lubricating oil system smoke exhaust fan flue gas, simple structure is reliable, design benefit can with the lubricating oil recovery that part should directly arrange in the atmosphere recycle, not only be favorable to environmental protection, changing waste into valuables again, reduced enterprise's lubricating oil purchasing cost, kill two birds with one stone.
