Abstract
The utility model relates to gas mixing equipment, in particular to a structure for improving a mixing effect of gas mixing equipment. The structure comprises a pipeline, one or more annular distributing pipes in the pipeline, and spraying holes in the annular distributing pipeline (s), wherein the annular distributing pipeline (s) is or are connected with a gas inlet pipe through a distributing pipe, and the one or more annular distributing pipes are arranged in the pipeline. According to the utility model, the problem of poor local mixing effect caused by dead angle of fluid flowing of the traditional mixing equipment during use is mainly solved, and especially, the problem of potential safety hazards caused by local concentration within an explosion range, possibly due to non-uniform oxygen and combustible organic matter gas in a gas phase oxidation reaction is solved.
Description
Technical field
The utility model relates to the gas mixing apparatus, particularly a kind of structure that improves gas mixing apparatus mixed effect.
Background technology
The gas mixing apparatus is industries such as oil refining, petrochemical industry, chemical industry, medicine chemical industry equipments commonly used, particularly in gas phase oxidation.Oxygen need mix the back with flammable organic gas and get into reactor, and the ratio of organic gas and oxygen receives the restriction of explosion limit, must be controlled in certain scope.But mixing in a flash,, can bring unsafe factor to the device operation if the situation that local oxygen concentration in a big way is in explosive range appears in the mixer mixing poor effect.
Summary of the invention
The purpose of the utility model is to propose a kind of structure that improves gas mixing apparatus mixed effect; Mainly solve the existing gas mixing apparatus mobile dead angle that exists of fluid in use; Cause the local not good problem of mixing; Particularly oxygen mixes with flammable organic gas and uneven possibly cause local concentration in a big way to be in explosive range in gas phase oxidation, has the problem of potential safety hazard.
For realizing above-mentioned purpose, the utility model is to realize like this.
A kind of structure that improves gas mixing apparatus mixed effect is characterized in that: it comprises the spray orifice on pipeline, the interior annular spread pipe of pipeline and the annular spread pipe; Described annular spread pipe is connected with air inlet pipe through distributing pipe; Be provided with one or more annular spread pipes in the described pipeline.
The structure of described raising gas mixing apparatus mixed effect is characterized in that: a plurality of annular spread Guan Zaiyi plane.
The structure of described raising gas mixing apparatus mixed effect is characterized in that: a plurality of annular spread pipes are not or not a plane.
By said structure, the advantage of the utility model is.
When the utility model used, the atm number fluid directly through pipeline, had been eliminated fluid and has been turned to the problem that has dead angle, eddy current; Stingy amount gas sprays at a high speed through spray orifice; Meet at the primary air of outlet with atm number, two kinds of fluid contact backs form strong turbulent flow, have improved mixed effect effectively.
Description of drawings
Fig. 1 is to use the structural representation of the gas mixing apparatus of the utility model structure.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
The specific embodiment
See also Fig. 1-2, the utility model discloses a kind of structure that improves gas mixing apparatus mixed effect.As shown in the figure: it comprises pipeline 1, one or more annular spread pipes 2 and spray orifice 3, and annular spread pipe 2 is connected with air inlet pipe 5 through distributing pipe 4.
The primary features of the utility model is.
1. primary air directly through pipeline, has been eliminated fluid and has been turned to the problem that has dead angle, eddy current.Pipe diameter should guarantee that primary air has suitable flow velocity.
2, stingy amount gas to be mixed is through air inlet pipe, distributing pipe, annular spread pipe and spray orifice ejection.Nozzle hole number and diameter should be confirmed through calculating according to tolerance.Gas should improve turbulent extent with ejection at a high speed, guarantees mixed effect.
3, the annular spread pipe is in the high velocity air, should properly consider to support according to device diameters, prevents to cause vibration and damage.
Gas mixing apparatus described in the utility model is included as the gas mixing apparatus that various purposes are used.
Below come further to introduce the utility model through an embodiment.
Certain gas phase oxidation, the pipeline of employing DN 700.Oxygen inlet pipe diameter DN 100 is provided with three annular spread pipes altogether, and outer shroud adopts the pipe of DN 65 to bend, ring footpath 520 mm, and downstream direction has the spray orifice of 30 Φ 7; Middle ring adopts the pipe of DN 40 to bend, ring footpath 300 mm, and downstream direction has the spray orifice of 16 Φ 7; Interior ring adopts the pipe of DN 25 to bend, ring footpath 120 mm, and downstream direction has the spray orifice of 6 Φ 6.
Through using above-mentioned utility model structure, eliminated flow blind angle, improved the mixed effect of gas mixer, avoided local mix uneven problem and issuable danger.
An above-mentioned embodiment who is merely the utility model is not the practical range that is used for limiting the utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be the technological category of the utility model.
Claims (3)
1. structure that improves gas mixing apparatus mixed effect is characterized in that: it comprises the spray orifice (3) on the annular spread pipe (2) and annular spread pipe in pipeline (1), the pipeline; Described annular spread pipe (2) is connected with air inlet pipe (5) through distributing pipe (4); Be provided with one or more annular spread pipes (2) in the described pipeline (1).
2. the structure of raising gas mixing apparatus mixed effect according to claim 1 is characterized in that: a plurality of annular spread pipes (2) are on a plane.
3. the structure of raising gas mixing apparatus mixed effect according to claim 1 is characterized in that: a plurality of annular spread pipes (2) are not or not a plane.
