Abstract:
Disclosed are a method and a device for operating a generator (4) by means of hot gas, particularly hot gas obtained from the gasifier of a waste reprocessing plant, said hot gas being conducted across a double turbine rotor (13). In said method and device, steam (44) is introduced or generated upstream of the turbine (3) such that a hot gas-steam mixture (45) is introduced via a tapering turbine inlet (11) at an elevated density and a high speed, causing a preliminary reaction in the mixture. The hot gas-steam mixture (45) is then first expanded and once again compressed by means of the double turbine rotor (13) and is introduced in an expanding manner into a widening diffuser section (16) of the discharge pipe (15) in which a negative pressure prevails.
Abstract:
Disclosed are a method and an installation for generating effective energy by gasifying waste. In said method and installation, waste such as garbage is introduced into a shaft-type melting gasifier, is dried in a reverse flow, is degassed, and is gasified while the solid residue is melted. The hot crude gases that are withdrawn from the melting gasifier (15) are fed to a hot gas steam generator (18) in which steam is admixed to the hot gas and said hot gas-steam mixture is conducted across the double turbine rotor (18.13) of a turbine (18.3) that drives a power generator (18.4), a preliminary reaction taking place at the same time. The pre-purified hot gas-steam mixture is then introduced into a downflow device (38) in which the mixture is cooled and pre-purified using sprayed water mixed with reactant and by repeatedly expanding, compressing, and foaming the mixture, the pre-purified gas being withdrawn and the liquid being collected. The pre-purified gas is fed to a gas purification process (40) in which the pre-purified gas is foamed with reactant and is defoamed again. The purified gases are finally further utilized for generating power, e.g. by being burned in an engine (41).
Abstract:
The invention relates to a method and an installation for treating liquids, especially for purifying contaminated water. Said method consists of the following steps: the raw water is pre-purified by adding a foam-forming reaction agent; the pre-purified water undergoes a main purification process by foaming the water with ionising radicals contained in the exhaust from the subsequent steps, in a known perforated cylinder washer (21); the foam formed is eliminated; the de-foamed water is ionised; and the impurities in the purified water are sedimented. The purified water is then additionally purified, the mud consisting of impurities from the pre-purification and the main purification process is physically separated, and the transformation of raw water into purified water is carried out continuously.
Abstract:
Combustion fumes are cleaned, prior to emission by contact with foam produced by turbulence in cleaning liq. The turbulence is produced by freely working rollers (13) dipping below the surface of a bath (15) of the liq. and with peripheral indentations for gas energising into a prim. reaction chamber (11a). The internal roller cavity forms a secondary reactor chamber (11b) assymetrically bounded by the roller surface. Used foam is taken by a conduit (16) to be broken down, e.g. by a motor-driven radial fan producing regenerated cleaning liq. in a collector (18) while cleaned gas leaves from a pipe (25).
Abstract:
A gas cleaning process esp. for flue gases, involves contacting a foam-forming reactant with the gas in a reaction chamber, destroying the foam after reaction, separately collecting recovered reactant and sludge and releasing the cleaned gas. When cleaning gases at below 60 deg. C, (a) foam destruction is carried out in the reaction chamber to form a dense foam and an underlying reactant layer mixed with water and gases; (b) the dense foam and surface sludge are withdrawn from the reaction chamber by suction and are temporarily stored for gravity sepn., and (c) material layer-spen. is carried out in a settling phase, the individualy layers being successively sepd. When the gases are at above 60 deg. C the settled sludge is dried in a dryer by stepwise vertically downward transport of the sludge in contact with dirty gas fed to the dryer. Also claimed is a plant for carrying out the process, including a reaction chamber contg. rotating rolls for contacting the gases with the reactant.

Abstract:
In continual process to treat effluent wash water, in a first stage a foam-building reactant is admixed to the water with air in a rotating perforated drum. The reactant forms bubbles in water containing ionized radicals introduced from subsequent stages. Foam is skimmed off and the water ionized, driving sedimentation. Sludge is then physically removed from the first-stage treated water and the foam-treated water. Foam generation and removal, oxidation, ionization and collection of treated water takes place in a vertical gravity-driven sequence within the same assembly. Gases liberated with radicals by the ionization process are returned to the foam generation reaction stage and are recycled within a closed system. Also claimed is a commensurate assembly with a pre-cleaning tank (10) into which foam generating agent is admixed and the pH is regulated (13, 14). The assembly has a main treatment block (20) with vertically stacked drum station (21), foam generation station (23), ionization station (24), clean water tank (25), sludge separator (30) and sumps (11, 26). The assembly further has a filter (40) and a clean water discharge (43).
