Abstract
The utility model discloses a gas mixing device, which comprises a first gas inlet tube, a second gas inlet tube and a gas outlet tube, wherein the first gas inlet tube and the gas outlet tube construct an integral pipeline; and the second gas inlet tube is inserted into the integral pipeline, and is used for partitioning the integral pipeline into the first gas inlet tube and the gas outlet tube. Gas in the second gas inlet tube is sprayed at the angle of 360 degrees through a gas hole, and the flowing turbulence of gas in the pipe is increased, so that the gas mixing effect is greatly improved. The gas mixing device has the advantages of easiness for designing and constructing, good gas mixing effect and increase in the gas mixing accuracy.
Description
Technical field
The utility model relates to a kind of gas mixer.
Background technology
Sometimes the gas that needs concentration, pressure stability in the commercial production, so the device of uniform mixing gas mixture is a key equipment wherein.Existing gas mixer is a simple three-way pipe, and two kinds of gases form mist after preliminary the mixing.Though this structure is very simple, because pipe network distance is shorter, the effect of mixing when big or flow velocity is very fast when gas flow is relatively poor, can not satisfy in the commercial production the accurate requirement to gas concentration.
The utility model content
The utility model provides a kind of gas mixer for addressing the above problem, and it has design of being easy to and construction, the advantage that the gas mixed effect is good.
In order to solve above-mentioned technical problem, the utility model adopts following technical scheme.
The gas mixer of the utility model; Comprise first air inlet pipe, second air inlet pipe, escape pipe; Said first air inlet pipe and escape pipe are the pipelines of one, and second air inlet pipe is inserted in the pipeline of above-mentioned one, and the pipeline of one is divided into first air inlet pipe and escape pipe.
As the further improvement of the utility model, said second air inlet pipe is inserted the part of the pipeline of one, is provided with pore along the circumference of caliber.
Said pore is arranged in along on the circumference of caliber with 60 ° of plum blossoms.
Said second air inlet pipe is inserted the part of the pipeline of one, and end can be blind dead.
The pipeline of said second air inlet pipe and one is 0 ° of-90 ° of angle.
Can be provided with gas concentration analyzer on the said escape pipe.
Said first air inlet pipe and second air inlet pipe have at least one to be provided with flow control valve.
The utility model can be according to the different processes situation; Like flow, caliber, pressure, resistance etc., the angle, second air inlet pipe of setting second air inlet pipe and first admission line inserts length and the pore opening on second air inlet pipe of one pipeline, the number of pore etc.
The utility model can mix two or more gas with various.
When the gas mixer of the utility model is worked; Gas in second air inlet pipe through pore with the direction of 360 degree spray to around; Owing to strengthened the disturbance of gas flow in the pipe, the gas mixed effect is improved greatly, on escape pipe, can be provided with gas concentration analyzer; And analysis result is sent into the DCS control room monitor, if being set, regulating system can adjust the mixed concentration of gas automatically.
The gas mixer of the utility model can also be provided with respectively the PID controller that links to each other with flow control valve with gas concentration analyzer; Measuring the value of coming according to gas concentration analyzer regulates pid parameter; Through this automatic adjustment circuit; Gas concentration can be regulated automatically, alleviates operational ton greatly, and improves the accuracy that gas mixes.
The beneficial effect of the utility model: be easy to design and construction, the gas mixed effect is good, has improved the accuracy that gas mixes.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein, 1, first air inlet pipe; 2, second air inlet pipe; 3, escape pipe; 4, pore; 5, gas concentration analyzer; 6, flow control valve; 7, flow control valve.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Embodiment 1: of Fig. 1, the gas mixer of present embodiment comprises first air inlet pipe 1, second air inlet pipe 2, escape pipe 3.Said first air inlet pipe 1 is pipelines of one with escape pipe 3, and second air inlet pipe 2 is inserted in the pipeline of above-mentioned one with 90 ° of angles, and the pipeline of one is divided into first air inlet pipe 1 and escape pipe 3.Said second air inlet pipe 2 is inserted the part of the pipeline of one, and is terminal blind dead, is provided with the pore of arranging with 60 ° of plum blossoms 4 along the circumference of caliber.Said escape pipe 3 is provided with gas concentration analyzer 5.Be respectively equipped with flow control valve 6 and flow control valve 7 on said first air inlet pipe 1 and second air inlet pipe 2.
When the gas mixer of the utility model is worked; Gas in second air inlet pipe 2 through pore 4 with the direction of 360 degree spray to around; Owing to strengthened the disturbance of gas flow in the pipe; The gas mixed effect is improved greatly, and the gas concentration analyzer 5 on the escape pipe 3 is sent the concentration analysis result into the monitoring of DCS control room.
Embodiment 2: on the basis of embodiment 1; Also be provided with respectively the PID controller that links to each other with flow control valve 6, flow control valve 7 with gas concentration analyzer 5; Measure the value of coming according to gas concentration analyzer pid parameter is regulated, through this automatic adjustment circuit, gas concentration can be regulated automatically; Alleviate operational ton greatly, and improve the accuracy that gas mixes.
Though the above-mentioned accompanying drawing that combines is described the specific embodiment of the utility model; But be not restriction to the utility model protection domain; One of ordinary skill in the art should be understood that; On the basis of the technical scheme of the utility model, those skilled in the art need not pay various modifications that creative work can make or distortion still in the protection domain of the utility model.
