Abstract
The utility model provides the technical scheme of a nitrogen scavenging blow device for mixed fuel gas burners, which mainly comprises a nitrogen tank, a nitrogen delivery pipe connected with the nitrogen tank, and a front pressure sensor, a pressure-reducing valve group, a back pressure sensor and a safety valve which are installed on the nitrogen delivery pipe. In the technical scheme, the nitrogen delivery pipe after the safety valve is connected with a stabilizing tank, an electromagnetic valve is also installed on the nitrogen delivery pipe in front of the stabilizing tank and an outlet valve of the stabilizing tank and an inlet valve of the stabilizing tank are also installed on the nitrogen delivery pipe in front of and behind the stabilizing tank. The structure can ensure that the pressure of output nitrogen is stabilized within the pressure range of 2.8 to 3 Mpa required by a burner in a scavenging blowing process and a partition sealing process.
Description
Affiliated technical field:
The utility model relates to a kind of fuel gas generation unit device therefor, especially a kind of air mixture combustion machine is with the clear blowing apparatus of nitrogen.
Background technology:
The air mixture that is to use in the gas-steam combined circulating generation, air mixture are that blast furnace gas and the coke-stove gas after purified treatment fully mixes in proportion, and meet the combustion gas of combustion machine calorific value requirement.But when the combustion machine starts, still to use light diesel fuel to start, after the combustion machine is stable, switch to air mixture again and normally move.Because air mixture has the characteristic of inflammable, explosive and easy poisoning, be blowing clearly and separating technology of medium so the combustion machine adopts high pressure nitrogen, when the combustion machine moves with light diesel fuel, cut off air mixture with high pressure nitrogen; When the combustion machine carries out fuel when switching, purge the air mixture pipeline with high pressure nitrogen, avoid air to mix and set off an explosion with air mixture; When the combustion machine moved with air mixture, high pressure nitrogen came the exclusion seal air, therefore, high pressure nitrogen to the combustion machine blow clearly with exclusion seal be vital.In the prior art, use be nitrogen pot and with the tank connected nitrogen gas delivery-line of nitrogen, and the preceding pressure sensor of on nitrogen gas delivery-line, installing, pressure-reducing valve group, back pressure sensor and safety valve, this structure, when nitrogen flow when blowing clearly big, prior art can't realize quick, the accurately adjusting of nitrogen pressure, causes output pressure to fluctuate widely, and can't satisfy production requirement.When in exclusion seal, because the nitrogen of pressure-reducing valve group leaks, cause the nitrogen pressure after the pressure regulation slowly to rise, pressure rises to certain limit will cause the safety valve quick pressure releasing, and the combustion chance is shut down because of sealing load descends.Therefore, prior art can't guarantee that output pressure is stabilized in the confidential 2.9 ± 0.1Mpa pressure limit asked of combustion when blowing with exclusion seal clearly, and this is the existing in prior technology weak point.
Summary of the invention:
The utility model is at the existing in prior technology deficiency, and provides a kind of air mixture combustion machine with the clear blowing apparatus technical scheme of nitrogen, and this scheme has increased a stable can and magnetic valve on the basis of existing technology.Stablize the nitrogen pressure of output with stable can, regulate too high nitrogen pressure, when blowing clearly, be stabilized in the confidential 2.9 ± 0.1Mpa pressure limit asked of combustion with exclusion seal so can guarantee the nitrogen pressure of exporting with magnetic valve.
This programme is realized by following technical measures: mainly comprise nitrogen pot and with the tank connected nitrogen gas delivery-line of nitrogen, and the preceding pressure sensor of on nitrogen gas delivery-line, installing, pressure-reducing valve group, back pressure sensor and safety valve, the characteristics of this programme are that the nitrogen gas delivery-line behind described safety valve connects a stable can.The concrete characteristics of this programme also have, and magnetic valve also is housed on the nitrogen gas delivery-line before described stable can.On the forward and backward nitrogen gas delivery-line of described stable can, stable can outlet valve and stable can inlet valve are housed also.
The beneficial effect of this programme can be learnt according to the narration to such scheme, because in this scheme, after pressure sensor and the safety valve, connect a stable can and magnetic valve after the preceding pressure sensor of on the tank connected nitrogen gas delivery-line of nitrogen, installing, the pressure-reducing valve group in nitrogen gas delivery-line.Because descending fast to system's nitrogen pressure, stable can has mitigation, thus energy systems stabilisation nitrogen gas pressure, and can decide the volume of stable can according to the demand of system to nitrogen.Can control decompression when system's nitrogen pressure is too high at installation magnetic valve behind the safety valve, when blowing clearly, be stabilized in the confidential 2.9 ± 0.1Mpa pressure limit asked of combustion with exclusion seal with the nitrogen pressure that guarantees output.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings:
Fig. 1 is the structural representation of the utility model specific embodiment.
1 is the stable can outlet valve among the figure, and 2 is stable can, and 3 is magnetic valve, and 4 is the stable can inlet valve, and 5 is safety valve, and 6 is nitrogen gas delivery-line, and 7 is the back pressure sensor, and 8 is the pressure-reducing valve group, and 9 is preceding pressure sensor, and 10 is nitrogen pot.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, the air mixture of this programme combustion machine is with the clear blowing apparatus of nitrogen, comprise nitrogen pot (10) and the nitrogen gas delivery-line (6) that is connected with nitrogen pot (10), and the preceding pressure sensor (9) of going up installation in nitrogen gas delivery-line (6), pressure-reducing valve group (8), back pressure sensor (7) and safety valve (5), this programme is that the nitrogen gas delivery-line (6) behind described safety valve (5) connects a stable can (2), and preceding at described stable can (2), after nitrogen gas delivery-line (6) on stable can outlet valve (1) and stable can inlet valve (4) also are housed.On the preceding nitrogen gas delivery-line (6) of described stable can (2), magnetic valve (3) is housed also.
