By using the gas mixer, two kinds of gases can be mixed quickly, uniformly and fully.

Description

Gas mixer

Technical field

The utility model relates to the gas mixer technical field, is specifically related to a kind of gas mixer that supplies two kinds of gases to mix or mix exchange reaction.

Background technology

In the commercial production application process, two kinds of gas need mix or common using gases blender when mixing exchange reaction.Existing gas mixer generally is in a container, to feed two kinds of gases simultaneously, carries out freely mixing through the diffusion motion between the gas then, and this gas hybrid mode exists mixes abundant inadequately and even, the slow deficiency of mixing velocity.

Summary of the invention

The technical problem that the utility model solved is the deficiency to above-mentioned existence, can make two kinds of gases mix and mix more all even sufficient gas mixer rapidly and provide a kind of.

The technical scheme that the utility model adopted is: gas mixer comprises main air inlet pipe, sneaks into the gas air inlet pipe, ring pipe, shunting taper inlet duct, mozzle, mixing chamber and choke apparatus; The said gas air inlet pipe of sneaking into is connected with ring pipe; Said shunting taper inlet duct is made up of a component stream tapered snorkel that is no less than 4; The wide mouth end of every shunting tapered snorkel is connected with ring pipe, and the slot end of every shunting tapered snorkel is connected with main air inlet pipe, and said main air inlet pipe is connected with mozzle; Mozzle also is connected with mixing chamber, and said choke apparatus is arranged in the internal cavities of mixing chamber.

Said mozzle is the closed-entry mozzle, and the wide mouth part of closed-entry mozzle is connected with main air inlet pipe, and the necking end of closed-entry mozzle is connected with mixing chamber.

The connecting portion of said closed-entry mozzle and mixing chamber, the sectional area of mixing chamber is greater than the sectional area of closed-entry mozzle.

Said shunting taper inlet duct is made up of 10～30 shunting tapered snorkel.

Said mixing chamber shell is provided with and unloads slag chute.

Said choke apparatus comprises choked flow tube and support bar, and choked flow tube is connected with mixing chamber through support bar.

The beneficial effect of the utility model is: 1, through being provided with and sneaking into ring pipe that the gas air inlet pipe is connected and the shunting taper inlet duct of being made up of a component stream tapered snorkel that is no less than 4; Sneaking into gas its pressure after getting into the shunting tapered snorkel strengthens gradually; And the gas of sneaking into after the pressurization gets into the main air inlet pipe from a plurality of different azimuth and mixes mutually with mainstream gas, thereby makes the mixing of two kinds of gases more all even rapidly; 2,, the pressure of mist is strengthened gradually, thereby accelerate the mixing of two kinds of gases through the closed-entry mozzle is set; 3, because the connecting portion of closed-entry mozzle and mixing chamber; The sectional area of mixing chamber is greater than the sectional area of the necking end of closed-entry mozzle; When mist gets into the sudden enlargement of mixing chamber time space from the closed-entry mozzle; Pressure moment of mist reduces, and two kinds of gases are mixed more equably; 4, through in the internal cavities of mixing chamber, choke apparatus being set, mist is further spread, impel the degree of depth mixing more fully of two kinds of gases; 5, unload slag chute through on the mixing chamber shell, being provided with, help the discharging and the cleaning of waste residue; 6, use the utility model, can make two kinds of gases mix and mix more all even fully rapidly.

The specific embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explanation.

A kind of gas mixer comprises main air inlet pipe 1, sneaks into gas air inlet pipe 2, ring pipe 3, shunting taper inlet duct, closed-entry mozzle 5, mixing chamber 6 and choke apparatus.Sneaking into gas air inlet pipe 2 is connected with ring pipe 3; Shunting taper inlet duct is made up of 12 shunting tapered snorkels 4; The wide mouth end of every shunting tapered snorkel 4 is connected with ring pipe 3, and the slot end of every shunting tapered snorkel 4 is connected with main air inlet pipe 1; Main air inlet pipe 1 is connected with the wide mouth part of closed-entry mozzle 5, and the necking end of closed-entry mozzle 5 is connected with mixing chamber 6; Choke apparatus is arranged in the internal cavities of mixing chamber 6, and choke apparatus comprises choked flow tube 7 and support bar 10, and choked flow tube 7 is connected with mixing chamber 6 through support bar 10; At the connecting portion of closed-entry mozzle 5 with mixing chamber 6, the sectional area of mixing chamber 6 is greater than the sectional area of closed-entry mozzle 5; The shell of mixing chamber 6 is provided with and unloads slag chute 8.Said shunting taper inlet duct can be made up of the shunting tapered snorkel that is no less than 4 according to actual needs, preferably is made up of 10～30 shunting tapered snorkels.

In use; Sneak into gas and get into ring pipe 3 from sneaking into gas air inlet pipe 2; Get into main air inlet pipe 1 through each root shunting tapered snorkel 4 again; Because the effect of shunting tapered snorkel 4 strengthens the pressure of sneaking into gas gradually, and the gas of sneaking into after the pressurization gets into the main air inlet pipe 1 from a plurality of different azimuth and mixes mutually with mainstream gas, thereby makes the mixing of two kinds of gases more all even rapidly; Mist gets into mixing chamber 6 through closed-entry mozzle 5 again and carries out degree of depth mixing; On the one hand because the effect of closed-entry mozzle 5 strengthens the pressure of mist; Thereby accelerate the mixing of two kinds of gases; On the other hand because mist gets into mixing chambers 6 time space sudden enlargements from closed-entry mozzle 5, pressure moment of mist reduces, and makes more even that two kinds of gases mix; Mist entering mixing chamber 6 backs make two kinds of gases mix more fully owing to choked flow tube 7 stops that mist further spreads; Solid slag in the mist unloads slag chute 8 below the mixing chamber 6 can falling under the gravity effect, is convenient to the discharging and the cleaning of waste residue; Well-mixed mist is discharged from exhaust outlet 9 at last.
