Definitions

the invention relates to a method for operating immersion in front of flare systems or in front of exhaust gas burnings, a gas stream being introduced into the immersion via an immersion pipe immersed in a liquid, and immersion.
the present invention is therefore based on the object of demonstrating a method of the type mentioned at the outset and immersion which prevent liquid discharge from the immersion by almost 100% separation of the liquid in the immersion. In addition, pulsation of the gas flow is to be effectively prevented.
This backflow is achieved through hydrostatic pressure build-up in the plenum.
circulation of the liquid is maintained within the immersion via the flow of the liquid entrained by the gas flow and via a backflow into the accumulated liquid.
This procedure has the advantage that the liquid circulation (circulation) regulates itself.
This is advantageously accomplished in that the liquid strands flow into an outer annular space of the immersion, the liquid flowing from there into a storage space and from the storage space via at least one refill opening, preferably a refill tube, into an inner annular space, where the gas flow through the immersion tube counteracts the liquid is led. Due to its inertia, a liquid circulation operated in this way effectively prevents oscillation of the liquid level in the inner and outer annular space and thus prevents pulsating gas discharge from the immersion associated with the vibrations of the liquid level in the two annular spaces.
Baffles are advantageously used as internals that generate streaks of liquid.
the strands of liquid can be generated by several rows of deflector plates, preferably by two rows.
the rows of deflector plates should be staggered in the vertical direction, so that the strands of liquid from the first flow deflector plates meet the deflector plates of the row of deflector plates arranged below.
the gas flow is directed against the pent-up liquid via a dip tube end formed with a sawtooth profile.
a swirl flow can be generated by a helical toothing of the saw teeth of the dip tube end. This can support the subsequent separation of the gaseous and liquid phases.
the immersion is operated in such a way that a loading of the gas / liquid flow, i.e. a ratio of the mass of the liquid to the mass of the gas, between 3 and 5 occurs.
the immersion according to the invention is characterized by a centrally and vertically arranged immersion tube, an inner annular space arranged around the lower immersion tube end, which is delimited on the outside by a guide tube projecting over the lower immersion tube end, one at an angle of 70 to 110 °, preferably perpendicular to Immersion tube arranged baffle screen with a deflector collar arranged at its outer end at an angle of 70 to 110 °, preferably 90 °, on which internals producing fluid streaks are attached, and a collecting space which is fluidically connected to the inner annular space and which is directed outwards from the outer jacket of the immersion is limited.
the immersion according to the invention is characterized by a relatively simple construction which enables any person skilled in the art to design the immersion for a special application without any problems.
the pressure loss during immersion can be calculated or estimated particularly well in the case of a specific gas flow and liquid load. This can significantly increase the safety of the system.
the internals consist of symmetrically arranged deflector plates.
the deflector plates are preferably roof-shaped, i.e. in the form of an upside down "V", with an angle of 15 to 90 °, preferably 20 to 40 °.
V upside down
the advantages of immersion described above result when the lower end of the immersion tube has a sawtooth profile. As already mentioned, the saw teeth can be arranged obliquely to generate a swirl flow.
the inner annular space is fluidly connected to the collecting space on its inside by at least one refill opening, preferably a centrally arranged refill tube.
a centrally arranged refill tube When using a centrally arranged refill pipe, this should limit the inner annulus on the inside.
the diameter of the refill opening or the refill tube advantageously has 20 to 50%, preferably 30 to 40%, of the diameter of the dip tube.
the inner annular space and the collecting space are not connected directly via the refill opening (s) or the refill tube (s), but rather the refill opening (s) or the refill tube (s) is / are in an intermediate wall is installed which, together with the guide tube, delimits a storage space which has openings to an outer annular space, ie the collecting space is divided into an outer annular space and a storage space.
This can be accomplished, for example, by extending the guide tube to the base of the immersion. In this way, the increased vibration damping can more effectively prevent the risk of vibrations occurring in the liquid during immersion. Openings between the storage space and the outer annular space in the form of slots or rows of holes arranged in the lower region of the storage space have proven particularly suitable.
the total area of the openings in the guide tube is advantageously 1 to 5 times the cross-sectional area of the refill opening (s) or the refill tube (s).
the refill opening (s) or the refill tube (s) in particular acts as an attenuator for vibrations of the liquid in the inner and outer annular space.
a gas flow 1 is introduced into the immersion via a centrally and vertically arranged dip tube 2.
the pressure in the gas flow 1 keeps the liquid in the inner annular space 4 at a medium gas load at a liquid level which is below the liquid level in the outer annular space 10.
the gas flow 1 is deflected by 180 ° between the saw teeth 3 of the dip tube end, liquid being entrained and ejected from the inner annular space 4.
the liquid flows partially upwards under the action of the slightly rotating gas flow 15 as a wall film along the guide tube 8. Liquid drops are absorbed by the gas flow, a gas / liquid flow being formed. This strikes at high speed the baffle screen 12 arranged perpendicular to the immersion tube 2, which is equipped with a deflecting collar 13 which is attached to the outer end of the baffle screen and is arranged parallel to the immersion tube 2. On the inside of the deflector collar 13, deflector plates 14 are mounted in two rows. The flow is deflected by the impact screen 12 and the deflecting collar 13 by approximately 180 °, as a result of which a liquid film is formed. The liquid film is divided into individual liquid strands by the deflector plates 14 acting as flow dividers.
the gas can escape from the immersion almost unhindered with little pressure loss and without entraining liquid (17).
the strands of liquid flow (16) due to the effect of gravitation and due to the conservation of momentum, into the liquid dammed up in the outer annular space 10, the liquid strands flowing off essentially via the outer jacket 9 of the immersion into the liquid of the outer annular space 10.
the phase separation that has already taken place enables an almost pulsation-free operation of the diving.
the liquid reaches the storage space 6 from the outer annular space 10 via the slots 11 provided at the lower end of the guide tube 8. This is delimited at the top by the intermediate wall 7, the liquid flowing from the storage space 6 via the refill tube 5 into the inner annular space 4.
the outer annular space 10 and the storage space 6 are closed at the bottom by the bottom wall 18.
