Title: Multipurpose gas purification process for the reduction of nitrogen oxides
Inventor: DOLATA TILO DIPL ING
IPC: B01D53/56
Filed: 1993-03-24
Abstract: The invention serves for purifying industrial exhaust gases. The gaseous, liquid and solid pollutants are eliminated or greatly reduced by means of a 10 stage scrubbing at temperatures of 40 to 110 DEG C and slight vacuum of approximately 100 mm water column. The multipurpose gas purification process is particularly suitable for the purification of nitrogen oxide-containing exhaust gases. The NOx transformation proceeds through the following process steps:   transformation of the nitrogen oxides NO and NO2 in a dry activated coke bed into nitrogen; additional adsorption of inorganic and organic pollutants (e.g. SO2, HCl, HF, dioxins, furans, etc.) and retention of dusts,   heating to 110 DEG C by injection of saturated steam,   spray absorption with NH3-water or urea solutions, catalytic reaction of NOx with NH3 or urea solutions to form nitrogen and water in the activated coke bed,   water-spray scrubbing, repeated liquid-phase separation and discharge during the purification process,   adding fresh air as required.   All purification steps and process sequences are arranged in a simple horizontal or vertical, easily handled metal or plastic combination scrubber.

Title: Cooling apparatus
Inventor: KOCH THOMAS
IPC: F25D3/10
Filed: 1993-07-12
Abstract: The choke effect (Joule-Thomson effect) can be technically utilised to lower the temperature of a medium below its inversion line. However, the differences in density which appear here are difficult to utilise or cannot be utilised at all to drive the process. The object was to create an apparatus which is temporarily independent of an energy source and by means of which cooling becomes possible without heating of an external heat source being necessary during the process, in the course of which no quantities of coolant or only small quantities of coolant evaporate into the ambient. To achieve the object, several coolant tanks thermally insulated from one another are connected to one another in a circle according to the invention by non-return, pressure-relief and choke valves and are fastened to a rotatably mounted, inclined plane. Separately mounted heat accumulators are arranged at the periphery of the coolant tanks.

Abstract: The invention relates to a rotary slide valve (1, 2) with a centring device (24, 25, 28, 29) loaded by the force of a spring (27) and a pressure. In a simple type of construction, the centring device is to be capable of being accommodated inside the rotary slide valve (1, 2) and is to respond in a sensitive manner to pressure changes. According to the invention, the rotary slide (1) has a segment-like extension (15) which engages between radially opposite drivers (16 and 16A) formed by the output shaft (4). Rolling bodies (24) are arranged in recesses (20 to 23) between the extension (15) and the drivers (16, 16A). The rolling bodies (24) are loaded by a pressure ring (25), against which an annular piston (28) presses. The annular piston (28) has an end face which faces a reaction chamber (29) and on which the spring (27) and a variable pressure act. Since the pressure ring (25) has a conical surface (26) inclined to the inside, the rolling bodies (24) are pressed inwards, so that control adjustment of the rotary slide valve (1, 2) is made more difficult as pressure rises in the reaction chamber (29). <IMAGE>
