Description

A kind of burning crude oil device

Technical field

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

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 device, air and crude oil mixing do not hook fully, and burning crude oil is not abundant, ring Border 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 device.

This utility model one better embodiment provide a kind of burning crude oil device, including burning crude oil head and with described combustion Burn the burner boom that head connects, described burning crude oil head includes air line, crude oil pipeline and ignition system, described air hose stage property There is air duct, enter for air, described crude oil pipeline has crude oil passage, enter for crude oil, on described crude oil pipeline It is provided with the air inlet of multiple cross-distribution.

Preferably, the plurality of air inlet radial angle is 25 degree.

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.

Brief description

In order to be illustrated more clearly that the technical scheme in this utility model embodiment, below will be to required in embodiment description Accompanying drawing to be used be briefly described it should be apparent that, drawings in the following description are only that of the present utility model some are real Apply example, for those of ordinary skill in the art, on the premise of not paying creative work, can also be attached according to these Figure obtains other accompanying drawings, wherein:

Fig. 1 is the schematic cross-section of the burning crude oil head of this utility model burning crude oil device；

Fig. 2 is the air inlet expanded schematic diagram of burning crude oil head shown in Fig. 1；

Fig. 3-Fig. 6 is burning crude oil head air described in Fig. 1 and crude oil hybrid analog-digital simulation schematic diagram.

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 device is included burning crude oil head and is connected with described burning crude oil head Burner boom.Described burning crude oil head includes air line 10, crude oil pipeline 20 and ignition system 30.Described air line 10 has There is air duct, enter for air.Described crude oil pipeline has crude oil passage, enters for crude oil.Described crude oil pipeline 20 It is provided with multiple air inlets 40, described air is passed through described air inlet 40 entrance crude oil pipeline and mixed with described crude oil, and former Oil-piping exit is atomized, and is then lighted by ignition system 30.Proportion relation in pipe of crude oil and air and mixing journey The combustion position that degree is directly connected to outside is diffusion combustion or premixed combustion, has influence on the after-flame degree of crude oil.

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.In present embodiment, the cut-in angle of described air inlet 40 is in the axial direction side of described crude oil pipeline 20 It is 45 ° upwards, 25 ° in the radial direction.In this utility model other embodiment, the cut-in angle of described air inlet 40 is in institute State between being 30～60 ° on the axial direction of crude oil pipeline 20, in the radial direction between 12～32 °.

Refer to Fig. 3, be the shaft section mixture velocity distribution representing described burning crude oil head；Refer to Fig. 4, be table Show the shaft section volume of air score distribution of described burning crude oil head；Refer to Fig. 5, be the outlet representing described burning crude oil head Section volume of air score distribution；Refer to Fig. 6, 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 the crude oil pipeline of this utility model burning crude oil device, air is entering crude oil pipeline chamber When internal, there is tangential velocity, eddy flow can be formed, degree of mixing can be effectively improved.

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.
