A modular construction micro-reactor with parallel microchannels on fluid guide plates for chemical reactions, but not for evaporation purposes is known. A modular construction falling film evaporator is disclosed, comprising a stack of alternate gap-like evaporation chambers and sheet-like evaporator modules with an assembly of parallel microchannels, whereby the evaporation chambers are open above and/or below across the whole width of the module and the stack is arranged in a container. The falling film evaporator is used in a method for obtaining a gaseous phase from a liquid medium on a technical scale and is suitable for the concentration of thermolabile solutions and rapidly adjustable production of a gas stream.

The present invention discloses a microreactor for performing heterogeneous catalytic reactions, being of plate or stack construction for industrial use, with provision made for chambers between the plates for the chemical reaction and for the heat removal. Inside the reaction chambers, catalyst material is applied to the internal walls or filled into recesses, and in all chambers there are spacers. In particular the slot-shaped reaction chambers have channels with a hydraulic diameter smaller than 1500 &#x3bc;m and a ratio of free slot width to free slot height in the range of 10 to 450.

This emptying station is suited for emptying contents from bulk bags, especially bulk bags containing particulate hazardous materials as their contents. The emptying station includes a bulk-bag receptacle body having a top opening and bottom outlet, a bulk-bag cutting subassembly in the receptacle body, a raisable and lowerable top closure, and a sealing structure. The cutting subassembly includes at least three cutters each having an associated blade facing upwards, with the cutters collectively arranged to define a pyramid having an apex, and puncture pin positioned at the apex to point upwardly. In operation, a bulk bag is suspended from the top closure, then lowered with the top closure to pass the bulk bag into the receptacle body and cause the substantially flat bottom of the bulk bag to be pieced by the puncture pin and cut by the blades of the cutters to start emptying contents from the bulk bags to the bottom outlet. The sealing structure seals gaps formed between inner surfaces of the side walls and the bulk bag to prevent dust from escaping through the top opening. As the bulk bag is emptied, the top closure continues to lower until the top closure is positioned in a closed state in the top opening. Spray nozzles are preferably arranged in the receptacle body for external and/or internal rinsing of the emptied bulk bag.

Emptying station for bulk bags, and process of emptying bulk bags in the station

An emptying device for bulk bags having an inner and outer sack in which disturbances during emptying and contact with the bulk material are avoided. The device includes a holding device for the bulk bag, a double tube device arranged centrally beneath the holding device and having an inner tube, an outer tube arranged around the inner tube with an outlet fitted to its lower edge, and a closing ring which can be raised and lowered for closing the upper end of the annular gap formed by the two tubes. The device can additionally include at least one gripping device for securing the sack outlet of the inner sack, which gripping device can be moved up and down within the inner tube and can be pulled downwards by means of a pulling device operable from outside the double tube device.
