    摘要： Die Erfindung beziehtsich auf eine hydraulisch angetriebene Hochdruck-Kolbenpumpe zur Förderung von heissen oder kalten Fördermedien mit Feststoffpartikeln, wie z.B. einer Kohlenmaische. Die Pumpe besteht erfindungsgemäss aus einem geschlossenen Pumpenzylinder mit Ein- und Austrittsventilen für das Fördermedium an den beiden Enden des Pumpenzylinders und Ein- und Austrittsventilen für die Hydraulikflüssigkeit beidseitig neben einer mittleren in dem Pumpenzylinder befestigten Trennwand und einem inneren in Achsrichtung des Pumpenzylinders in diesem hin- und herbeweglichen Doppelkolben, bestehend aus den beiden äusseren Kolben und einer oder mehreren diese verbindenden Kolbenstangen, die durch eine oder mehrere Gleitlager in der Trennwand geführt sind und den beiden gegensinnig gleichzeitig grösser und kleiner werdenden äusseren Förderräumen zwischen den Kolben des Doppelkolbens und den Stirnwänden des Pumpenzylinders sowie den beiden ebenfalls gegensinnig gleichzeitig grösser und kleinerwerdenden Hydraulikräumen zwischen derTrennwand und den Kolben des Doppelkolbens.

    摘要： The method for cleaning chemical process and hydrocarbon processing apparatuses is performed by establishing a closed flow circulation loop, under specific operating conditions and in the presence of hydrocarbon-based fluids. The cleaning method is monitored by performing chemical/physical analysis. After cleaning the apparatus(es) can be immediately inserted back into the process. An optional degassing step can also be performed, in case the apparatus(es) has to be disassembled for inspection of maintenance.

    摘要： A coke oven door frame cleaning apparatus ofthis invention provides complete cleaning of the door frame (6), more particularly, the sealing surface (7) and the inner surface (8) of the door frame (6). The cleaning apparatus completely washes away by means of high pressured fluid the tary deposits persistently stuck on the surfaces. Possible damage on these surfaces (7, 8) due to cutters and/or scrapers is avoided. The apparatus comprises an upstanding main frame (13) mounted on a carriage (10) and supporting two upstanding sub-frames (2, 3) each carrying nozzles (9) to which the pressure fluid is supplied. The nozzles (9) on alarger one (2) of the sub-frames direct the pressure fluid onto the sealing surface (7) whilst the nozzles on a smaller one (3) of the sub-frames direct fluid onto the inner surface (8) of the oven door frame (6), the sub-frames (2, 3) being positionally adjustable on the main frame (13).

    摘要： A method for decoking the inner wall of a metal cavity, comprising pressurizing the metal cavity closely and depressurizing the metal cavity rapidly. In the above-mentioned decoking method, by firstly pressurizing the metal cavity and then depressurizing same rapidly, substances such as volatile hydrocarbons, water and so on inside a coke block are vaporized rapidly due to the drastic change in the pressure difference, and then the coke block is burst and detached from the inner wall of the metal cavity, and finally the decoking work is completed. The above-mentioned decoking method is rapid, simple and easy to operate, and the decoking efficiency can be greatly improved.

    摘要： A process vessel cleaning tool comprises a metal tube which can be introduced through an insertion port and sealing assembly into a high temperature vessel which permits the metal tube to be advanced progressively into the vessel by a suitable dnve mechanism without substantial leakage of gases from the vessel The metal tube supplies liquid under pressure to a cleaning tool head located at the leading end of the metal tube The tool head has a rolling contact element which is axially displaced a short distance from a rotary jet nozzle head The rolling contact element permits the tool head to pass readily over rough surfaces of vessel passages and around changes in direction within the vessel The metal tube is capable of being introduced into the vessel while it is in operation This tool is especially useful in process cyclones.
