Abstract
The invention provides a dual-fuel supply control system. The dual-fuel supply control system comprises an oil storage tank, an alcohol fuel oil supply pipeline and a natural gas supply pipeline, wherein the alcohol fuel oil supply pipeline is connected to the oil storage tank, and the alcohol fuel oil supply pipeline and the natural gas supply pipeline are respectively connected with a plurality of application facilities through an alcohol fuel oil distribution trunk pipeline and a natural gas distribution trunk pipeline. When natural gas is instable in pressure or suddenly stopped from supply, a fuel oil replenishing system can automatically start to automatically deliver sufficient replenished fuel to burning equipment or reduce input of the fuel oil, while the fuel oil replenishing system can automatically stop when the pressure of the natural gas is restored. Thus, the requirement for sufficient heat of the burning equipment is guaranteed, time delay and inconvenience in manual starting of the facilities are overcome, the problem about stable operating of the facilities at the same time is solved, cost in a lump is saved, and production efficiency is improved.
Description
Technical field
The present invention relates to industrial combustion raw material supply apparatus field, specially refer to a kind of oil-gas two-way fuel supply control system.
Background technology
At present, industrial energy is in short supply, natural gas and oil fuel are under-supply, the industrial equipment of combustion heating that needs adopts natural gas and fuel oil or Aalcohols fuel wet goods double fuel mode (being called for short " oil-gas two-way ") to heat mostly, and when the unexpected air pressure of natural gas is unstable or stop the supple of gas or steam, need the supply of manual operation startup oil supply system or conversion oil supply system, to reach postcombustion object, very inconvenient like this; In addition, when there are many combustion apparatus in large enterprise, need to give a fueller of each equipment configuration to reach the object of abundant postcombustion, cost is very high like this, uses also inconvenient simultaneously.
Summary of the invention
In order to overcome the defect of prior art, the invention provides following technical scheme:
A kind of oil-gas two-way fuel supply control system, comprise oil storage tank and be connected to the alcohol fuel oil supply line on oil storage tank, also comprise a natural gas supply pipeline, described alcohol fuel oil supply line and natural gas supply pipeline by alcohol fuel oil, shunt main conduit respectively and the shunting of natural gas shunting main conduit is connected to some application apparatus.
Further, on described alcohol fuel oil supply line from described oil storage tank to alcohol fuel oil shunting main conduit install successively alcohol fuel oil supply line main valve, hand valve, strainer valve, oil pump, the first pressure transmitter, the first magnetic valve, on the alcohol fuel oil supply line at described oil pump two ends across establishing one second magnetic valve.
Further, on described natural gas supply pipeline, from feed end to natural gas, shunting main conduit is installed natural gas supply pipeline main valve, the second pressure transmitter and the 3rd magnetic valve successively.
Further, described the first pressure transmitter, the first magnetic valve, the second magnetic valve, the second pressure transmitter and the 3rd magnetic valve are connected with a pressure switch board, are provided with PLC and frequency conversion converter in described pressure switch board.
The beneficial effect that the present invention brings is: when natural gas air pressure is unstable or stop the supple of gas or steam suddenly, fuel oil replenishment system is opened the inlet to combustion apparatus or minimizing fuel oil by sufficient postcombustion automatic transport automatically, and postcombustion system is closed down automatically after gas pressure recovers, thereby not only guarantee that combustion apparatus obtains sufficient heat demand, has also avoided the waste of fuel; When multiple devices are worked simultaneously, system can regulate postcombustion supply in real time according to main pipeline pressure, and subtube also can regulate postcombustion supply in real time according to the pressure of self, thereby meet many equipment works simultaneously, overcome manually respectively to the time delay of each device start and inconvenience, also solve the problem of multiple devices Simultaneous Stabilization work, saved input cost one time, improved production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Referring to Fig. 1, a kind of oil-gas two-way fuel supply control system, comprise oil storage tank 8 and be connected to the alcohol fuel oil supply line 6 on oil storage tank 8, also comprise a natural gas supply pipeline 10, described alcohol fuel oil supply line 6 and natural gas supply pipeline 10 by alcohol fuel oil, shunt main conduit 15 respectively and 16 shuntings of natural gas shunting main conduit are connected to some application apparatus.
On alcohol fuel oil supply line 6 from described oil storage tank 8 to alcohol fuel oil shunting main conduit 15 install successively alcohol fuel oil supply line main valve 7, hand valve 5, strainer valve 4, oil pump 3, the first pressure transmitter 2, the first magnetic valve 1, on the alcohol fuel oil supply line at described oil pump 3 two ends across establishing one second magnetic valve 12.On natural gas supply pipeline 10, from feed end to natural gas, shunting main conduit 16 is installed natural gas supply pipeline main valve 11, the second pressure transmitter 13 and the 3rd magnetic valve 14 successively.The first pressure transmitter 2, the first magnetic valve 1, the second magnetic valve 12, the second pressure transmitter 13 and the 3rd magnetic valve 14 are connected with a pressure switch board 9.9 pairs of current pressures of switch board are made corresponding signal output the PLC by wherein and frequency conversion converter and are controlled motor and complete the control to fuel-flow control.Set a rated pressure first to natural gas supply pipeline 10, when lower than this pressure, switch board 9 outputs signal to Aalcohols fuel supply line 6, opens the first magnetic valve 1, the second magnetic valve 12, starts oil pump 3 and regulates the oil pump capacity of oil pump 3.When natural gas returns to rated pressure, close the first magnetic valve 1, the second magnetic valve 12 and oil pump 3.Certainly in order to meet needs oil storage tank and the supply line of a plurality of equipment, be not limited to the quantity shown in figure, can be more.
The present invention can guarantee the production of many application apparatus, and oil-gas two-way is complementary, overcomes single use underaction defect easily, has improved production efficiency.
The above; it is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
