Description

A kind of burning crude oil head

Technical field

This utility model is related to petroleum exploration field, particularly a kind of burning crude oil head.

Background technology

Double based propellant device is mainly used in the petrochemical plants operation in offshore oil exploration, is that offshore drilling platformses can not Or the key equipment lacking.In existing burning crude oil head, air and crude oil mixing do not hook fully, and burning crude oil is not abundant, environment Pollution is larger.

Utility model content

In order to solve the above problems, what this utility model offer was a kind of makes burning crude oil sufficient burning crude oil head.

This utility model one better embodiment provides a kind of burning crude oil head, including air line and crude oil pipeline, institute State air line and there is air duct, enter for air, described crude oil pipeline has crude oil passage, enter for crude oil, institute State 5 rows that crude oil pipeline is provided with along described crude oil pipeline cross-distribution and be used for for 40 that air enters crude oil pipeline and crude oil enters The air inlet of row mixing.

Preferably, multiple described air inlets are 30～60 ° with regard to the axial angle of described crude oil pipeline, and radial angle is 12 ～32 °.

Preferably, described air inlet is 45 ° with regard to the axial angle of described crude oil pipeline, and radial angle is 25 °.

Compared to prior art, the air inlet cross-distribution of crude oil pipeline of the present utility model, air is entering crude oil pipe When in road cavity, there is tangential velocity, eddy flow can be formed, degree of mixing can be effectively improved.

Specific embodiment

Technical scheme in this utility model embodiment will be clearly and completely described it is clear that described below Embodiment is only a part of embodiment of the present utility model, rather than whole embodiments.Based on the enforcement in this utility model Example, all other embodiment that those of ordinary skill in the art are obtained under the premise of not making creative work, broadly fall into The scope of this utility model protection.

Refer to Fig. 1, this utility model burning crude oil head includes air line 10, crude oil pipeline 20 and ignition system 30. Described air line 10 has air duct, enters for air.Described crude oil pipeline has crude oil passage, enters for crude oil Enter.Described crude oil pipeline 20 is provided with multiple air inlets 40, and described air passes through described air inlet 40 and enters crude oil pipeline and institute State crude oil mixing, and in the atomization of crude oil pipeline exit, then lighted by ignition system 30.Crude oil and air joining in pipe The combustion position being directly connected to outside than relation and mixability is diffusion combustion or premixed combustion, has influence on crude oil After-flame degree.

Refer to Fig. 2, be the expanded schematic diagram of described air inlet 40.As shown in Fig. 2 axially dividing along described crude oil pipeline 20 It is furnished with 5 rows totally 40 air inlets 40.In described crude oil pipeline 20 radially, described each pore 40 cross-distribution that discharges into (is pitched Row).By described air inlet 40, air enters described crude oil pipeline 20 and more can be sufficiently mixed with crude oil, so that Burning crude oil is more abundant.Refer to Fig. 3-Fig. 4, in present embodiment, the cut-in angle of described air inlet 40 is in described crude oil The axial direction upper angle of pipeline 20 is 45 °, and radial direction upper angle is 25 °.In this utility model other embodiment, Between the cut-in angle of described air inlet 40 is 30～60 ° on the axial direction of described crude oil pipeline 20, in the radial direction 12 Between～32 °.

Refer to Fig. 5, be the shaft section mixture velocity distribution representing described burning crude oil head；Refer to Fig. 6, be to represent The shaft section volume of air score distribution of described burning crude oil head；Refer to Fig. 7, be that the outlet representing described burning crude oil head cuts Face volume of air score distribution；Refer to Fig. 8, be the outlet mixture velocity distribution representing described burning crude oil head.

Crude oil and air mixture burning whether cmpletely depend on the proportioning of crude oil pipeline chamber air and crude oil with And troubled water.For the quantitative description fuel whether burned fuel that completely, we are overflowed using surrounding border and spraying into The ratio of fuel represents the remaining rate of fuel, and burn-off rate then subtracts remaining rate for 1.0.Found by calculating, in above-mentioned embodiment, , more than 99%, therefore combustion position is good, and mixture is fully burned for the burn-off rate of mixture.

The air inlet cross-distribution of this utility model crude oil pipeline, air has tangential when entering in crude oil pipeline cavity Speed, can form eddy flow, can effectively improve degree of mixing.

The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every The equivalent structure made using this utility model description or equivalent flow conversion, or directly or indirectly it is used in other phases The technical field closed, is all included in the same manner in scope of patent protection of the present utility model.
