Abstract

The power oil cooler that a kind of blast-furnace top gas recovery turbine generates electricity, belongs to oil cooling apparatus technical field, for being cooled down to power oil.Its technical scheme is:Oil return bypass is added on power oil cooling line, one end of oil return bypass is connected with the oil returning tube of power fuel tank, the other end of oil return bypass is connected with cooling line, and tie point is located between coolant circulation pump and power oil cooler, and oil return valve is provided with oil return bypass.The utility model causes power oil to be directly entered cooling line from the oil returning tube of blast-furnace top gas recovery turbine generator, power fuel tank is back to again after the cooling of power oil cooler, so power oil need not just open coolant circulation pump in cooling procedure, greatly save electric power.The utility model is simple in construction, easy to use, cooling effect good, can not only save electric energy, also eliminate the operation and maintenance of coolant circulation pump, adds the reliability of blast-furnace top gas recovery turbine generating.

Description

The power oil cooler that a kind of blast-furnace top gas recovery turbine generates electricity
Technical field
The utility model is related to the power oil cooler of the large scale equipments such as blast-furnace top gas recovery turbine generating, air blower, Belong to oil cooling apparatus technical field.
Background technology
, it is necessary to be carried out to power oil in the running of the large scale equipments such as blast-furnace top gas recovery turbine generating, air blower Cooling.Current power oil cooler includes coolant circulation pump, power oil cooler, cooling line, and power oil is from power oil Bottom portion enters power oil cooler through the cooled circulation pumped of cooling line, again by cold after the cooling of power oil cooler But pipeline returns to power fuel tank, and so circulation is carried out.The shortcoming one of this cooling device is to consume energy higher, and two be coolant circulation pump Reliability constrain the function of cooling device.Specifically, first, coolant circulation pump motor is 2.2KW, and summer needs 24 are small When open incessantly, use substantial amounts of electric energy.Secondly, need in the process of running to coolant circulation pump carry out long-term monitoring and Safeguard, it is ensured that the normal of coolant circulation pump is used, to maintain the cooling of power oil to circulate.Once coolant circulation pump breaks down, The cooling of power oil will be directly affected, and then influences the operation of the large scale equipments such as blast-furnace top gas recovery turbine generating, air blower, because This requires that coolant circulation pump has very high operational reliability and rapid-maintenance ability.
Utility model content
Technical problem to be solved in the utility model is to provide the power oil cooling that a kind of blast-furnace top gas recovery turbine generates electricity But device, this power oil cooler can ensure the cooling effect to power oil, while can reduce power consumption and subtract Few dependence to coolant circulation pump.
Solving the technical scheme of above-mentioned technical problem is:
The power oil cooler that a kind of blast-furnace top gas recovery turbine generates electricity, it includes cooling line, coolant circulation pump, moved Power oil cooler, the two ends of cooling line are connected with power fuel tank respectively, and coolant circulation pump and power oil cooler connect respectively It is connected in cooling line, power fuel tank has oil supply pipe and oil returning tube to be connected with blast-furnace top gas recovery turbine generator, Its improvements are to add oil return bypass, and one end of oil return bypass is connected with the oil returning tube of power fuel tank, by oil return The other end on road is connected with cooling line, and the tie point of oil return bypass and cooling line is located at coolant circulation pump and power oil cooling But between device, oil return valve is installed in oil return bypass.
Stop valve is added on the power oil cooler that above-mentioned blast-furnace top gas recovery turbine generates electricity, the cooling line Door, cutting-off valve is arranged on the cooling line that oil return is bypassed between tie point and coolant circulation pump.
The beneficial effects of the utility model are:
The utility model adds oil return bypass between the oil returning tube of power fuel tank and the cooling line of power fuel tank, So that power oil is further separated into the cooling line of power oil from the oil returning tube of blast-furnace top gas recovery turbine generator, pass through Power fuel tank is back to after the cooling of power oil cooler again, such power oil is in cooling procedure just without opening cooling circulation Pump, greatlys save electric power.The utility model is simple in construction, easy to use, cooling effect good, can not only save electric energy, The operation and maintenance of coolant circulation pump is also eliminated, the reliability of blast-furnace top gas recovery turbine generating is added, with significant Economic benefit, is worth of widely use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Marked in figure as follows:Power fuel tank 1, cooling line 2, coolant circulation pump 3, power oil cooler 4, cooling nozzle 5, Oil supply pipe 6, oil returning tube 7, oil return bypass 8, oil return valve 9, cutting-off valve 10.
Embodiment
The utility model by cooling line 2, coolant circulation pump 3, power oil cooler 4, cooling nozzle 5, oil return bypass 8, Oil return valve 9, cutting-off valve 10 are constituted.
Shown in figure, the two ends of cooling line 2 are connected with power fuel tank 1 respectively, coolant circulation pump 3 and power oil cooling Device 4 is connected in cooling line 2, and power fuel tank 1 has oil supply pipe 6 and oil returning tube 7 to be sent out with blast-furnace top gas recovery turbine Electric installation is connected, and this structure is as good as with prior art.
Shown in figure, improvements of the present utility model are the increase in oil return bypass 8.One end of oil return bypass 8 and power The oil returning tube 7 of fuel tank 1 is connected, and the other end of oil return bypass 8 is connected with cooling line 2, oil return bypass 8 and cooling line 2 tie point is located between coolant circulation pump 3 and power oil cooler 4.Add after oil return bypass 8, power oil can be from height The cooling line 2 of power oil is directly further separated into the oil returning tube 7 of producer gas waste pressure turbine TRT, by power oil cooling But device 4 is back to power fuel tank 1 again after cooling down, and such power oil need not just open coolant circulation pump 3 in cooling procedure, significantly Electric power is saved.
Shown in figure, oil return valve 9 is installed in oil return bypass 8, oil return can be controlled by oil return bypass 8.
Shown in figure, cutting-off valve 10 is added on cooling line 2, and cutting-off valve 10 is arranged on oil return and bypasses 8 tie points On cooling line 2 between coolant circulation pump 3.When oil return bypass 8 is directly with power oil cooler 4, cut-out can be closed Valve 10;If necessary to accelerate cooling, stop valve 10 can be opened, starts coolant circulation pump 3, accelerates the power oil of power fuel tank 1 Circulation.
