Abstract
The utility model relates to a gas mixer which comprises a gas mixing chamber, an air inlet pipe, an oxygen inlet pipe and a mixed gas outlet pipe. One end of the gas mixing chamber is provided with the air inlet pipe, and the other end is provided with the oxygen inlet pipe; the mixed gas outlet pipe is arranged at the side face of the gas mixing chamber near an air inlet end; and the air inlet pipe is arranged inside the gas mixing chamber, wherein, one end of the air inlet pipe is connected with an air inlet, and the other end is provided with a plurality of mutually staggered slotted holes, and a conical cap is arranged at the end part of the air inlet pipe. Compared with the prior art, the utility model has the advantages of fast, stable and even gas mixing, and the like.
Description
Technical field
The utility model relates to gas mixer, is specifically related to a kind of gas mixer for two kinds of gases mixing.
Background technology
Adopting oxygen-enriched air to replace air-melted in metal smelt is to strengthen to produce, cut down the consumption of energy, reduce environmental pollution, enhance productivity, increase the great technical measures of business efficiency.
Oxygen-enriched air smelting be utilize the oxygen-enriched air blast in the stove zone, stove air port with add coke in the stove and the sulfide in the furnace charge and carry out the vigorous oxidation reaction and produce a large amount of high-temperature furnace gas and high-temperature fusant, heat and mass transport fully takes place with furnace charge in the high-temperature furnace gas that is produced in the process that rises by the bed of material, its temperature reduces gradually, oxygen content also reduces gradually, and SO
2Concentration but constantly raise, entered flue by high-temperature blower by pipeline then, carry through flue and go relieving haperacidity to handle.Therefore the air that blasts in the stove need be an oxygen-enriched air, and oxygen-enriched air generally is by oxygen and air are mixed, and existing gas mixer mixes slow, follows the tracks of slow (general about 30 minutes), can't satisfy the demand of product oxygen concentration frequent variations.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of mixed gas speed fast, steady, uniform gas mixer for the weak point that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: gas mixer, it is characterized in that, this blender comprises mixing chamber, oxygen inlet pipe, air intlet pipe, gaseous mixture escape pipe, described mixing chamber one end is provided with the oxygen inlet pipe, the other end is provided with the air intlet pipe, this air intlet tubular axis is in extending to mixing chamber, afterbody at the air intlet pipe is provided with a plurality of slotted eyes that stagger mutually, and being provided with the awl cap at its tail end, described gaseous mixture escape pipe is arranged on the mixing chamber radial side.
Described oxygen inlet pipe is a conical pipe.
The tail end of described air intlet pipe extends near the oxygen inlet pipe.
Described slotted eye is provided with 2～20, and the area of each slotted eye equates.
Described slotted eye comprises rectangle slotted eye or circular hole.
Described a plurality of slotted eye is arranged on the radial side of air intlet pipe afterbody.
Described gaseous mixture escape pipe is located at mixing chamber near the air intlet end, and is set for the eccentric.
Compared with prior art, gas mixer of the present utility model is separately positioned on the mixing chamber two ends with the inlet tube of air and oxygen, the air intlet pipe is delivered to air near the oxygen inlet tube, and the slotted eye of offering by its afterbody flows into mixing chamber, with the oxygen mix of coming from the taper oxygen inlet tube, the oxygen inlet pipe adopts conical pipe, can reduce fluid impact and resistance, air is by dispersing outflow in the slotted eye, increased the contact area when two kinds of gases meet greatly, and the gaseous mixture escape pipe is arranged on the mixing chamber side near the air intlet end, mixing chamber has certain-length, air and oxygen begin to mix in mixing chamber, and constantly collision contact, evenly mix the back and deliver to the user from the outflow of gaseous mixture escape pipe, and go out the gaseous mixture tracheae and adopt eccentric design, guaranteed that further gas mixes, obtained the gas of certain oxygen concentration, tolerance can reach 6250Nm after the proportioning
3/ h, the oxygen content scope can be 21%～85%.The utlity model has fast, steadily, characteristics such as mix, the oxygen content claimed range is wide, changes frequent.
