摘要:
A chemical reactor 1 for the reaction of fluid reaction mixtures is disclosed. The reactor includes at least one adiabatic reaction zone 2 with a catalyst bed 3 and at least one heat exchanger 4 downstream of the reaction zone 2. The heat exchanger 4 includes plates 5, 6 which are layered on top of one another and joined to one another. The individual plates 5, 6 have at least two separate fluid flow channels 7, 8 arranged in a predetermined pattern. The plates have fluid flow channels 7, 8 which are arranged so that the reaction mixture flows through the heat exchanger 4 in a first flow path direction and the heat-transfer medium used in the heat exchanger 4 flows through the heat exchanger 4 in a second flow path direction. The plates 5, 6 in the heat exchanger 4 are joined to one another by hard soldering.
摘要:
The invention relates to a gas distribution system which can be connected to a gas supply, the purpose of said gas distribution system being to admit and distribute a non-oxidizing gas in a shroud (17, 20, 21, 23) covering at least one solder container (22). Printed circuit modules (12) are transported through said shroud and while they are being transported, are brought into contact with a wave of solder (24). The gas distribution system has at least one gas distributor situated above and at least one gas distributor (19, 31) situated below the printed circuit modules (12) in order to produce a protective gas atmosphere with low residual oxygen values. Both gas distributors are provided with flow elements (48, 49, 51 to 56, 59; 35, 37, 44, 45). Said flow elements produce a displacement gas blanket which is distributed homogeneously over the discharge surfaces (59, 44, 45) directed towards the solder container.
