The task of the present invention is therefore to To train Ines Haßwäscher of the type mentioned at the beginning in such a way that £ the mesh energy depending on the gas to be cleaned is adjustable.

This task is done according to the invention in that as unread® of the pipe a protruding into the pipe, lifting and g @ SLKlbar © r kegalförattiger YerschluBkörper provided eats, -and

also the distance between the lower end of the tube and Fluid level is adjustable? Through the one at the bottom The conical closure body arranged in the © d @ s Rohras

this formed and the pipe, an annular gap, aer * is adjustable through and lowering the VerschluSkSrperß * By dies® setting Ringspeltes the speed can be de © initiated and regulate gas to be purified in the annular gap in any way, so that all rate-

can be searched through »d, h. also the usual one Hochlelstungaventuri washers are common ^

By changing the distance between the lower end of the pipe and the washing liquid level, either by raising and / or lowering the pipe or by changing the liquid volume in the container, the amount of liquid entrained can be iegulated independently of the adjustable speed »

these two features can thus be more precisely defined Regulate the washing energy in any way and that one achieve optimal gas cleaning under all conditions «

this training of the device according to the invention can changing gas volumes and gas pressures by setting the annular gap size or changing the distance between the Compensated for the end of the pipe and the washing liquid splegol

According to a further feature of the invention, the kogel angle of the conical closure body is preferably 15 °. This ensures that the flow conditions change little when there is a change in the height of the cone.

The invention will be explained in more detail below with reference to the drawing: FIG

Figo 1 is a schematic representation of the wet scrubber and the

Fig. 2-4 partial representations of different designs _a

The gas to be cleaned enters the cylindrical container 2 at 1, a Bs distributed outside around the pipe 3 and then exits again through the annular gap formed by the conical closure body 4 and the pipe 3. Thereby tear it from the washing liquid 6 la lower part of the container liquid droplets, which are atomized more or less finely depending on the gas velocity, old. There is an intensive exchange of momentum between gas and scrubbing liquid, as the liquid droplets are accelerated from 0 to gas speed _o The gas then flows upwards to the separation system, which consists of baffles 5, 5 * known per se. The liquid droplets are separated out by inertial forces. The conical closure body 4 is vertically adjustable and the gas speed in the annular gap can be changed without changing the flow conditions

Another possible configuration is shown in FIG. 4, in which the tube 3 * is replaced by a hollow cone. The centrifuged washing liquid runs through the pipe 3 (or other suitable cross-sections) back into the liquid reservoir 6 «up In this way there is no need for pumps or other conveying systems.

The setting of the washing liquid / air ratio for a given annular gap width is carried out by setting the liquid level , namely with fixed pipe 3 by lowering or raising the liquid level or with constant liquid level by raising or lowering the pipe 3 »In any case, this increases the distance between the lower end of the tube 3 and the WaschflUssigkeitsspiegel changes ge "the outlet of the purified gas is carried out at 7 _O
