Известен массообмевный аппарат с таиген1 ка шаым кводом газа, включающий корпус и патрубок дл подачи газа.A mass-exchange apparatus with a gas intake manifold is known, including a housing and a gas supply nozzle.

Окшако в известной конструкоии аппеурата газ уже иа очень небольшой высоте от ввода в шшарат движетс сплошным (поршневым ) потоком. Поэтому услови массообмена в верхней части аппарата ухудша ютс . Ююме того, вертикалы10 падаюоше капли жидкости иасыщаютс комп 1«1тами газа, и массоо ен замеол етс .Okshako, in the well-known design of gas, even at a very small height from the entrance to the shasharath, is moving by a continuous (piston) flow. Therefore, the mass transfer conditions in the upper part of the apparatus deteriorate. In addition, the verticals 10 drops of liquid droplets and are saturated with a computer of 1 to 1 tons of gas, and the mass transfer is quenched.

Цель нзобретеНи - интенсификаци процесса путем взаимодействи закручениого Лотсжа газа с жидкостью в мелкодисп гировшшом состо нии.The purpose of the invention is to intensify the process by the interaction of a gas with a swirling gas with a liquid in a finely dispersed state.

Это достигаетс тем, что патрубок дл :подачи газа выполшен в виде спирали, ко|тс а обхватывает весь цилиндрический аппарата, и в которую помеш вращакшийс обьемный распылитель, а ровшша им жидкость подаетс в эйну две жв1И газа в спирали. Над спиралью ра мешсв цевтробежиый брызгоул внтель.This is achieved by the fact that the nozzle for: gas supply is made in the form of a spiral, which encloses the entire cylindrical apparatus, and into which a volumetric nebulizer rotates, and the liquid that is rotated into the heine is fed two times in a spiral. Above the coil of the mesh of the stirruff sprinkler.

Claims

The headspace apparatus: contains a cylindrical hollow body 1, inside, which has a rotary volumetric sprayer 2. is installed through the entrance of the spiral 3 into the spiral 4, located in the junction part of the body 1. The headpiece 3 is in spiral 4, which is located in the junction part of the body 1. The headpiece 3 is in spiral 4, located in the junction part of the body 1. The key is in a spiral 4, which is located in the junction part of the body 1. 1 by 5 o (((vortex chamber). Both stages o6b: rf: Its sprayer 2 consists of rotating the state perforated hollow cylinder, the drift of the housing, supplying the first with reflection plates 6. First liter stage 7 | sprayer 2 serves for maximals and those vortex irrigation of the vortex chamber | yo its entire length, as well as partial irrigation of the gas coming out of the vortex chamber | into the upper part of the body. The second stage 8 of the atomizer 2 serves as a damper or absorber for the rising gases with a low concentration of the absorbed component. The gases go further into the centrifugal eye collector formed by the slit 9 in the upper part of the body 1 and the outer casing 10. The gases come out of the spray catcher through the pipe 11. In the lower part of the body 1 there is a bone, and participation in massoobmeno. Its level is maintained by overflow 12. The fluid in the lower part of the apparatus is circulated several times by means of pressure blades of a pump 13 immersed in it, which serves to supply fluid to the first stage of the spray gun 2 and which is a unit with the spray gun. The supply of liquid to the second stage is carried out with the help of pipe 14. -Discharge of liquid from the splash trap is carried out by pipe 15. The device can operate both UNDER overpressure and under vacuum to create a skim by an external rotor fan. Mass transfer apparatus operates as follows. The gas phase at high speed enters the vortex chamber, obrabovovannogo helix 4, as a result of what a strong vortex is formed. In this direction, all the way through the vortex chamber comes from the first stage 7 of the dispenser 2 fresh portions of irrigating liquid in the form of fine droplets. Throughout the entire vortex chamber, there is an intensive mass exchange both due to the high velocity of the gas, and due to the large contact surface of the phases and the developed Turbulent motion. A: The gas exiting the vortex chamber has a significant peripheral velocity. Therefore, it is moving for a relatively long time along a screw line with a small pinch on top of housing 1. Immediately after leaving the vortex chamber, the gas encounters a denser stream of droplets flying from the top of the atomizer 2. The large flux density is due to the narrowing of the cross section at a constant height the capacity of the floater 2. Moving even higher, the gas enters the zone of action of the second stage 8 of the atomizer 2. This stage 1b is fed by the fluid flowing through pipe 14. Step 8 serves to extract the absorbed component as completely as possible. and the gas phase. Therefore, in most cases, it is advisable to feed this stupa of the nebulizer with a clean absorber, which still goes to replenish the liquid phase, withdrawing the mass flow apparatus. If necessary, such steps Moxaof. To do several, then each postframe is fed with liquid collected from the spray in the previous stage. Due to the rotational movement of the gas, the significant part of the liquid droplets is separated in the cylindrical part of the housing 1} and flows in the form of iruieHfKH to the bottom. After the latter, the gas "1" and the gas phase enters the sprinkler formed by the slit 9 between the housing 1 and the lid 16 of the apparatus, where it drastically changes the direction of its movement. Here it is the separation of the smallest sprays that have not separated in the cylindrical part of housing 1. An additional separation of splashes occurs in the space between housing 1 and outer casing Y. Here, the cyclonic nature of gas movement along the casing leads to splash separation of splashes on the casing walls Y. The liquid phase, obtained from the spray, flows through the pipe 15 to the lower part of the apparatus, and the gas - to the outlet in the pipe 11. The claims 1. Mass transfer apparatus for carrying out, for example, gas absorption-desorption processes including a housing with a dispenser located inside it and a gas nozzle, which distinguishes c. In order to intensify the process by interacting with a swirling gas flow with a liquid in a finely dispersed state, the gas supply nozzle is designed in the form of a spiral in which the rotating volumetric sprayer is placed.

2. The apparatus according to claim 1, characterized in that, in order to reduce the volume of the mass of the co-exchange apparatus, a centrifugal drip head is placed above the spiral.
