Abstract
An octagon throat tube device for a 40,000 ton/year carbon black reaction furnace comprises a throat tube, raw material oil gun insertion ports, a furnace casing, a thermal insulation layer and a rubing grain pouring layer, wherein the rubing grain pouring layer, the thermal insulation layer and the furnace casing are sequentially arranged on the throat tube from inside to outside, the inner wall of the throat tube is in a regular octagon shape, eight raw material oil gun insertion ports are arranged on the throat tube, and the raw material oil gun insertion ports are respectively arranged on the perpendicular bisector of the octagon edge. Due to the fact the inner wall of the throat tube is in the regular octagon shape, raw material oil can be sprayed into the throat tube by eight raw material oil guns, and the raw material oil can form nearly round atomization oil drop shadow in the throat tube. Due to the fact that atomization oil drops are evenly distributed, carbon black generation reaction temperature is even. The particle diameter of generated carbon black is narrow in distribution, carbon black color intensity is effectively improved, and yield of raw oil is improved.
Description
Technical field
The utility model relates to a kind of production of carbon black trunnion device, relates in particular to a kind of 40000 tons of/year black reactor octagon trunnion devices.
Background technology
The trunnion that present domestic wet granulation black reactor uses is connected between combustion chamber and the reaction chamber, and in trunnion, raw oil contacts with high temperature gas flow; Form the atomizing oil droplet, the uniformity coefficient of atomizing oil droplet directly has influence on carbon black and forms particle size carbon black and carbon black tint strength, and existing trunnion inwall is circular; After raw oil sprays into trunnion through eight oil guns; Raw oil forms anistree star fogging oil and drips shade at the trunnion place, the oil droplet skewness that causes atomizing causes the soot formation temperature of reaction uneven; It is wide to make that the particle size carbon black that generates distributes, and carbon black tint strength is low.
Summary of the invention
The purpose of the utility model is to provide a kind of 40000 tons of/year black reactor octagon trunnion devices, and it has is evenly distributed the atomizing oil droplet, makes soot formation temperature homogeneous more, thereby improves the advantage of soot formation quality.
The utility model is realized like this; It comprises that trunnion, raw material oil gun insert mouth, furnace shell, thermal insulation layer, chromium corundum pouring layer; It is characterized in that trunnion from inside to outside is provided with chromium corundum pouring layer, thermal insulation layer and furnace shell successively; The inwall of trunnion is the octagon of rule, and trunnion is provided with eight raw material oil guns and inserts mouth, and the raw material oil gun inserts mouth and lays respectively on the midperpendicular on said octagonal limit.
The technique effect of the utility model is: because the inwall of trunnion is the octagon of rule; After raw oil sprayed into trunnion through eight raw material oil guns, raw oil formed sub-circular atomizing oil droplet shade in trunnion, because the atomizing oil droplet is evenly distributed; Make the soot formation temperature of reaction even; Make and improved the sooty tinctorial strength effectively by the particle size carbon black narrowly distributing that generates, improve the yield of raw oil.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the drawings, 1, trunnion 2, chromium corundum pouring layer 3, thermal insulation layer 4, furnace shell 5, raw material oil gun insert mouthful.
Embodiment
As shown in Figure 1, the utility model realizes that like this it comprises that trunnion 1, raw material oil gun insert mouth 5, furnace shell 4, thermal insulation layer 3, chromium corundum pouring layer 2; Trunnion 1 from inside to outside is provided with chromium corundum pouring layer 2, thermal insulation layer 3 and furnace shell 4 successively, and the inwall of trunnion 1 is the octagon of rule, and trunnion 1 is provided with eight raw material oil guns and inserts mouth 5; The raw material oil gun inserts mouth 5 and lays respectively on the midperpendicular on said octagonal limit, and during use, raw oil inserts mouth 5 through eight raw material oil guns and sprays in the trunnion 1; And mixes with high temperature and high speed air-flow in the trunnion 1, form the atomizing oil droplet, because inserting mouth 5, the raw material oil gun lays respectively on the midperpendicular on said octagonal limit; The atomizing oil droplet forms sub-circular atomizing oil droplet shade like this, and the sectional area ratio of raw oil atomizing oil droplet shadow zone and trunnion 1 increases, and reduce in the space; Furnace pressure raises, and the high temperature gas flow heat is absorbed by raw oil fast, and the cracking length of flame of raw material hydrocarbon shortens; Scission reaction fast, acutely makes the soot formation temperature of reaction more even, the particle size carbon black narrowly distributing that makes generation; The carbon black tint strength that generates improves, and the yield of raw oil improves.
