Description
Technical field
The utility model is related to a kind of premixed lamp cap for synthetic furnace of hydrogen chloride, is mainly used in hydrogen chloride synthetic furnace field.
Background technology
Lamp holder is the critical component of hydrogen chloride synthetic furnace, installed in hydrogen chloride synthesis furnace bottom, for be passed through, mix chlorine,
Hydrogen, and generate hydrogen chloride gas in the combustion reaction of lamp holder upper end.
Traditional hydrogen chloride quartz lamp head, it is many to be made of 2 layers be coaxially disposed or the straight-through sleeve pipe of 3 layers of pyroceram,
In use, chlorine walks internal layer, hydrogen walks outer layer.Have the disadvantage that the mixing of chlorine hydrogen is not abundant enough.Burn not thorough, product chlorination hydrogen purity
Not high, heat is concentrated upward, it is desirable to which flue blended space is highly big.
Patent No. CN201120078744 " a kind of quartz lamp holder for hydrogen chloride synthetic furnace " discloses a kind of hydrogen chloride and closed
Into stove quartz lamp head, including the inner and outer tubes being coaxially disposed, outer tube is straight pipe；The top of inner tube is hemisphere Shape closed knot
Some spray orifices are evenly distributed with structure, the hemispherical of inner tube.In use, hydrogen is passed through from outer tube, chlorine passes through inner tube top half
The spray orifice of spherical structure enters in synthetic furnace, with hydrogen mixed combustion, it is possible to decrease burning height, but there is flame to body of heater heat punching
Brush angle is big, injures big to furnace tube inwall；Hydrogen chloride is made that rate is high, the defect such as chloride ion-containing in product.
Utility model content
The technical problems to be solved in the utility model is：A kind of high mixing efficiency, output chlorination hydrogen purity height, pairing are provided
Into all smaller, the safe and reliable premixed lamp cap for synthetic furnace of hydrogen chloride of the heat injury of stove furnace wall and furnace roof.
Premixed lamp cap for synthetic furnace of hydrogen chloride described in the utility model, including the quartz glass inner tube being coaxially disposed and outer
Pipe, outer tube is straight pipe, and the top of inner tube is hemispherical enclosed construction, and the bottom of hemispherical enclosed construction sets inner tube to lead directly to
Section, the top of the straight-through section of inner tube, which is provided with the jet segment that cross section is plum blossom-shaped, jet segment, is distributed with spray orifice.
The jet segment of described plum blossom-shaped includes connecting by connecting plate between multiple arcs section, adjacent segmental arc, arc
Spray orifice is distributed with section.
Described segmental arc is set to four sections~seven sections.
Described outer tube top is higher by inner tube top 20mm~40mm.
Described spray orifice is evenly distributed on jet segment.
Inner and outer tubes are quartz glass, the jet segment plum blossom-shaped shape therein of plum blossom-shaped and conventional double offset ring spanner
It is the common knowledge of those skilled in the art etc. identical.During work, hydrogen is passed through from outer tube；Chlorine is passed through from inner tube, and chlorine
Gas is vertically injected into hydrogen paths by the spray orifice in inner tube plum blossom-shaped structure, forms special turbulence structure；Formed with hydrogen
Sufficiently premixing, mixed gas is fully burnt on lamp holder top upwards：Because chlorine is incorporated to hydrogen paths, gas is further improved
Speed；Flame vertical upwards, burns highly moderate, between long flame and short-flame；I.e. effectively drop control flame is to synthesis furnace body
Radiation injury, bottom flame drops again to heat injury at the top of flue, and bags height is smaller.Synthetic furnace combustion chamber major diameter
Than more reasonable.Outer tube top is higher by 20~40mm of inner tube top.It is sufficiently mixed for chlorine and hydrogen there is provided the sufficient time
And space；Just enter flame combustion area after ensureing mixed gas mixing fully.The purity of product hydrogen chloride is higher, be free of in product
Chlorion.
The beneficial effects of the utility model are：
1st, in use, hydrogen is passed through from outer tube；Chlorine is passed through from inner tube, and by the spray orifice in inner tube plum blossom-shaped structure,
It is vertical to be injected into hydrogen paths, form special turbulence structure；It is more fully mixed with hydrogen, uniformly；In product it is not chloride from
Son, it is high that rate is made in hydrogen chloride.The purity of product hydrogen chloride is higher.
2nd, because chlorine is incorporated to hydrogen paths, gas velocity is further improved；Flame vertical upwards, burns highly moderate, between
Between long flame and short-flame；That is effectively radiation injury of the drop control flame to synthesis furnace body, drops bottom flame at the top of flue again
Heat injury, bags height is smaller.Synthetic furnace combustion chamber draw ratio is more reasonable.
3rd, the utility model is different with conventional structure；It is a kind of premixed lamp holder, and hydrogen is passed through from outer tube；Chlorine is from interior
Pipe is passed through, and by the spray orifice in inner tube plum blossom-shaped structure, is vertically injected into hydrogen paths, forms special turbulence structure；Outside
Tube top end is higher by inner tube top 20mm~40mm.It is sufficiently mixed for chlorine and hydrogen there is provided sufficient time and space；Ensure
Just enter flame combustion area after mixed gas mixing fully.The purity of product hydrogen chloride is higher.
