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 dispersant can be used to prevent fouling in process equipment. The dispersant is particularly useful in applications such as the prevention of fouling of compressor blades in compressors used for ethylene production. The dispersant includes an admixture of isopropylhydroxyl amine and an N, N-dialkyl fatty acid amide.

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 invention relates to a gas cooling device for coke-oven gas containing condensing constituents. Said device comprises a gas conduit (6), through which the coke-oven gas flows, heat exchanger elements in said gas conduit that are traversed by a coolant and a spray device (2) located above the heat exchanger elements, the surface of the heat exchanger elements that faces the gas being wet by a liquid that is fed through the spray device (2). According to the invention, the heat exchanger elements (5) are configured as cooling plates (5), through which the coolant can flow and are combined with channel-forming spacers (7) to form at least one heat exchanger stack. The heat exchanger stacks are located in the gas conduit (6) with a vertical alignment of their cooling plates (5), the gas channels formed by the spacers (7) being sprayed from above by the liquid that emanates from the spray device (2) and being traversed by the coke-oven gas.

摘要:
A gooseneck cleaner for a coke-oven, said cleaner including a frame (15) mountable on the coke-oven lehr car (14), and a carriage (18) movable on said frame and carrying an elongate lance (19) having a nozzle (20) at its free end. The nozzle projects water forwardly and upwardly in a vertical plane in a starting rotational position of the lance. When the nozzle is in the mouth of a side tube (12) of the gooseneck (10) high pressure water is forced through the nozzle which is reciprocated by no more than 90 degrees from this vertical plane. The lance (19) is advanced and when the nozzle is fully within the side tube (12) the nozzle is rotated through 360 degrees fully to clean the peripheral surface of the side tube without causing water to flow into the down tube (11) of the gooseneck (10).
