Description
Technical field
The present invention relates to a kind of nozzle, specifically refer to a kind of gas field gas nozzle.
Background technology
In gas extraction and conveying code, blowdown pressure letdown is avoid that super high pressure accident occurs a kind of maximally efficient
Measure.In prior art, gas well is when carrying out blowdown pressure letdown, and the portion gas in gas well is derived by the general metal catheter that passes through,
The gas of derivation is made to decompose, to reduce borehole pressure by the way of burning.But when burning, the local of combustion head part holds
Easily occur temperature too high and cause substantial amounts of heat to be transferred near gas well by metal catheter, cause potential safety hazard；Further, in combustion
During burning, the natural gas in metal catheter and air are typically in combustion head external mix, and such processing mode can avoid sky
Right gas carries over metal catheter inwall and burns in the middle, and then reduces the probability of metal catheter generation bombing, but can cause gold
Belong to the combustion of natural gas at catheter tip insufficient, i.e. there will be portion of natural gas loss near combustion head, formed serious
Potential safety hazard.
Summary of the invention

Annular section be provided with heat storage, also include contiguous block and multiple air inlet lines, described contiguous block is set in the extension of central canal
Duan Shang, and the sidewall of contiguous block is connected away from the end face of described mixing chamber side with heat storage, described air inlet lines runs through even
Connect with central canal after connecing block.During use, the gas well under pressure is by natural gas transmission to air inlet pipe, simultaneously to multiple skies
Injecting substantial amounts of air in gas inlet pipe, now, the natural gas in air inlet pipe and the combustion-supporting gas in air inlet lines are in central canal
Converge, and enter in mixing chamber along central canal, and the inner cross sectional area of mixing chamber wants big compared with central canal, i.e.
Swiftly flowing gaseous mixture starts reduction of speed in mixing chamber, fully mixes in space the biggest in mixing chamber
Close, then burnt by gas outlet, and after being mixed in advance with natural gas by air, the efficiency of combustion at gas outlet is big
Big improve, prevent combustion of natural gas insufficient and cause part fuel gas loss near gas field, to reduce near gas field
Potential safety hazard.Wherein, at gas outlet, during during mixed gas vigorous combustion, produced heat can be transferred to by mixing chamber
At heart pipe so that natural gas is too high with the air ambient temperature when mixing, and is easily caused center under swiftly flowing state
Pipe generation bombing, and the annular section that inventor is between housing and central canal is provided with heat storage, and accumulation of heat physical ability is by center
The heat that pipe receives all absorbs, to reduce natural gas with air at the probability mixing generation blast.
Described air inlet lines tilts along the axis of central canal to the direction away from described mixing chamber.As preferably, air
Inlet pipe is obliquely installed so that air is after entering in central canal, and air natural gas that is oblique and that enter in central canal mixes, due to
The oblique entrance of air and horizontally entering into of natural gas so that air and natural gas carry out preliminary being mixed to form in central canal
Wadding stream, rather than in prior art, air and natural gas horizontally enter into simultaneously and form laminar flow in central canal, with ensure air with
Natural gas being evenly distributed in central canal, it is achieved the maximizing combustion efficiency at gas outlet.
Described mixing chamber is truncated cone-shaped, and the internal diameter of mixing chamber successively decreases along the flow direction of mixed gas.As preferably,
After mixing chamber, the air in gaseous mixture is the most equalize with the ratio shared by natural gas, utilizes mixing chamber two ends internal diameter
Difference so that gaseous mixture realizes accelerating before entering gas outlet, it is to avoid gaseous mixture is stagnated in mixing chamber, indirectly improves sky
So efficiency of combustion of gas.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the present invention is at gas outlet, and during mixed gas vigorous combustion, produced heat can be transferred to center by mixing chamber
At pipe so that natural gas is too high with the air ambient temperature when mixing, and is easily caused central canal under swiftly flowing state
There is bombing, and the annular section that inventor is between housing and central canal is provided with heat storage, and accumulation of heat physical ability is by central canal
The heat received all absorbs, to reduce natural gas with air at the probability mixing generation blast；
2, the air inlet lines of the present invention is obliquely installed so that air is after entering in central canal, and air is oblique and enters central canal
Interior natural gas mixing, due to the oblique entrance of air and horizontally entering into of natural gas so that air and natural gas are at central canal
Inside carry out the preliminary wadding stream that is mixed to form, rather than in prior art air and natural gas horizontally enter into simultaneously and in central canal shape
Stratified flow, to ensure air and natural gas being evenly distributed in central canal, it is achieved the maximizing combustion efficiency at gas outlet；
3, the present invention is after mixing chamber, and the air in gaseous mixture is the most equalize with the ratio shared by natural gas, utilizes mixed
Close cavity two ends internal diameter difference so that gaseous mixture realizes accelerating before entering gas outlet, it is to avoid gaseous mixture stops in mixing chamber
Stagnant, indirectly improve the efficiency of combustion of natural gas.
