本発明は塩基性と酸性との液体を合わせるための、高圧
ガス及びこれらの液体のための管路を備えた噴射混合ノ
ズルに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a jet mixing nozzle for combining basic and acidic liquids, with a high pressure gas and conduits for these liquids.

。It is known to produce jet products formed from acids and bases by mixing the liquids in question with one another and then jetting the mixture. This method of operation requires a high degree of dilution to control exotherm or avoid explosive reactions.

路とがある。In an improvement to this state of the art, injection mixing nozzles have been developed which allow mixing of basic and acidic liquids to take place immediately after injection. In this case, the heat of neutralization is then used to cover a small amount of the energy required for the evaporation of the dispersion medium or solvent. There is.

すなわち比較的小さい処理能力がある。ノズルの大きさ

の細かさも中和の程度も急速に低下することが判明した
。Injection mixing nozzles of the known construction, in which the inner conduits are for liquids and the outer conduits are for high-pressure gases (UK Patent No. 1188582), offer considerable advantages and in the case of premixing the components. Although it avoids the drawbacks of , it has a crucial flaw: relatively little processing power. It has been found that when the nozzle size and air throughput are increased to a still practicable extent, both the fineness of the injection and the degree of neutralization decrease rapidly at a total throughput of more than 150-200 J/h.
多数のノズルの使用はしばしば場所の理由から限界があ

ンプ２基、管継手、弁、場合によっては流量計からなる
定量供給装置が必要であるので、多数のノズルの設備費
が嵩むこと及び装置の見通しが劣化することである。The use of multiple nozzles is often limited for space reasons. A further disadvantage is that each nozzle requires its own metering system consisting of two metering pumps, fittings, valves, and in some cases a flow meter, increasing equipment costs and equipment outlook for a large number of nozzles. deterioration.
本発明の課題は公知の欠点がなくとくに生成物の均等度
が高くて処理量が大きい噴射混合ノズルをもたらすこと
である。The object of the invention is to provide an injection mixing nozzle which does not have the known disadvantages and which has a particularly high product homogeneity and a high throughput.
この課題は塩基性及び酸性の液体を合わせるための、高
圧ガス及びこれらの液体のための管路を備えた噴射混合

ス管路１、塩基性乃至酸性の液体のための少なくとも２
個の同心環状の管路２．３及び外側同心環状の高圧ガス
管路４を特徴とすることによって解決される。The purpose of this task is to provide a jet mixing nozzle for combining basic and acidic liquids with a high-pressure gas and lines for these liquids. to at least 2 for acidic liquids
This is solved by featuring two concentric annular conduits 2.3 and an outer concentric annular high-pressure gas conduit 4.
中央の高圧ガス管路と外側環状の高圧ガス管路との協力
の結果として両液体が強く互いに押しつけられ液体負荷
が大きい場合も徹底的な混合が達成されるようになる。As a result of the cooperation between the central high-pressure gas line and the outer annular high-pressure gas line, the two liquids are strongly pressed against each other so that thorough mixing is achieved even at high liquid loads.
公知の噴射混合ノズルに比べて中和度も微細噴射も決定
的に改良される。Compared to known injection mixing nozzles, both the degree of neutralization and the fine injection are significantly improved.
原則としては第三の液体たとえば第二の酸又は中性液体
のための別の同心環状の管路を設けて中央の高圧ガス管
路を囲んで液体用の三つの同心環状管路が存在している
ようにすることは可能である。三つの液体の噴射の場合
液体用環状管路の間に、噴射を強化するため、別の高圧
ガス管路を設けるのが有利なことがある。In principle there are three concentric annular conduits for liquids surrounding a central high pressure gas conduit with another concentric annular conduit for a third liquid, e.g. a second acid or neutral liquid. It is possible to do so. In the case of injection of three liquids, it may be advantageous to provide a further high-pressure gas line between the annular liquid lines in order to intensify the injection.
内側中央の高圧ガス管路と外側同心環状の高圧ガス管路
の高圧ガス用流過横断面の比率は有利に１：３乃至１：
１００とすべきである。予定の噴射能力約１０００１／
ｈの場合中央高圧ガス管路の横断面が０．０６７ｃｄ、
外側環状管路のものが０．４ｃｉであるときとくに有利
な結果が達成される。The ratio of the high-pressure gas flow cross sections of the inner central high-pressure gas line and the outer concentric annular high-pressure gas line is preferably from 1:3 to 1:
It should be 100. Planned injection capacity approximately 10001/
In the case of h, the cross section of the central high pressure gas pipeline is 0.067 cd,
Particularly advantageous results are achieved when the outer annular conduit is 0.4 ci.
中央の高圧ガス管路の出口は好都合にノズル出口の前方
へ数鶴引き出されてほぼ液体の噴射点において終わるよ
うにしである。これによって内側のガス送入の作用が強
化される。外側同心高圧ガス管路の直径が１８鶴である
ノズルでは内側の中央高圧ガス管路は他のガス・及び液
体出口の平面から約６ｆｉ突出している。The outlet of the central high-pressure gas line is advantageously drawn out in front of the nozzle outlet so that it ends approximately at the point of injection of the liquid. This strengthens the effect of the internal gas supply. In a nozzle where the outer concentric high pressure gas line has a diameter of 18 mm, the inner central high pressure gas line projects approximately 6 fi from the plane of the other gas and liquid outlets.

。In a further advantageous embodiment of the invention, the outer wall of the outermost annular high-pressure gas line tapers conically towards the nozzle outlet at least in the area of the opening, thus providing a central connection point for the high-pressure gas. form a guide towards.
噴射混合ノズルの運転のためには任意の加圧下のガスが
利用できる。空気のほかにたとえば窒素及び炭酸ガスま
たアンモニア又は水蒸気も適している。Any gas under pressure can be used to operate the injection mixing nozzle. In addition to air, nitrogen and carbon dioxide gases as well as ammonia or water vapor are also suitable, for example.
中央の高圧ガス管路のために外側同心環状の高圧ガス管
路用のものと同じガス圧に調整するのが好都合である。It is advantageous to set the same gas pressure for the central high-pressure gas line as for the outer concentric annular high-pressure gas line.
望ましい相異なる流過横断面の結果としてそのとき内側
高圧ガス管の高圧ガス量は外側高圧ガス管路のものより
著しく少ない。As a result of the desired different flow cross-sections, the amount of high-pressure gas in the inner high-pressure gas line is then significantly lower than that of the outer high-pressure gas line.
ガス圧が上昇するとある程度までは噴射の細かさ及び中
和の完全さも上昇する。運転上の理由から一般に４乃至
５気圧ゲージの範囲のガス圧が問題になるがそれより高
いガス圧も有利に使用できる。To a certain extent, as the gas pressure increases, the fineness of injection and the completeness of neutralization also increase. For operational reasons, gas pressures in the range of 4 to 5 atmospheres gauge are generally of interest, although higher gas pressures can be used to advantage.
噴射法を用いて液体の蒸発をしようとするとき中和熱で
は足りないなら高圧ガスの予熱を推奨する。When attempting to evaporate liquid using the injection method, if the neutralization heat is insufficient, we recommend preheating the high pressure gas.

Both liquids are introduced via inlet branches 5 and 6. High pressure gas is introduced via branches 7 and 8. The outer wall of the outer high pressure gas line 4 is shaped conically so that the gas flows towards a central integration point. Inner high pressure gas pipe 1

A piece of hard wood was applied to the board. A band of liquid was marked on the tp paper, and the individual droplets were very clearly visible in the green color.

However, the results were clearly better with the 5 atm air pressure gauges in the inner and outer high pressure gas conduits.

A hard filter paper was pasted on one side of the blade. When inserted into the center of the jet mixing drum, the distance from the jet mixing nozzle was approximately 120 cm. Prior to the experiment, tF paper was impregnated with an alcoholic solution of naphtho-lufthalein as an indicator and dried. The resulting color allowed one to recognize whether the impinging droplets were alkaline, acidic or neutral, and therefore how well the mixing had taken place. For injection, a 50° C. alkylpenzole sulfonic acid served as the first liquid and a sodium hydroxide solution served as the second liquid. The inserted rod was first rotated 360° as quickly as possible so that the filter paper side faced away from the jet mixing nozzle so that the filter paper was exposed to the jet stream for a very short time during rotation. Subsequently, the rod was immediately pulled out to terminate the injection.

Again, the results with the 4 atm gauge were still completely usable. Based on the coloring of the v1 paper it was possible to notice that there were only very few extremely coarse acid droplets.Increasing the air pressure in the high pressure conduits to 5 atm gauge improved the results. The neutralization was then virtually complete and the droplet fineness was satisfactory. British Patent No. 11885
When the injection mixing nozzle described in No. 82 was used, good results were obtained in terms of throughput of alkylpenzole sulfonic acid 15,014/h and sodium hydroxide solution 30,117 h and air pressure at 4 atm gauge. The injection was fine and the neutralization was satisfactory. Acid 200j! /h and 40m of alkaline liquid! /h, the jetting quality significantly deteriorated.
