Abstract
Official abstract text for this publication.
With a device for influencing the flow, particularly in a horizontal connecting pipe ( 1 ) between a coal gasification reactor and a gas cooler/purifier, a solution is supposed to be created, whose task consists in being able to reduce or shut off the gas stream of a hot synthesis gas, if necessary, without being exposed to the great stresses caused by the corrosiveness and the high temperatures, while avoiding complicated valves or regulation devices. This is achieved by means of a Venturi constriction in the flow path of the gas in the pipe ( 1 ), as well as a flow cone ( 4 a ) positioned on a push rod ( 4 ) that is disposed centrally, whereby a connecting rod system ( 4 b ) that is guided to the outside is provided to move the push rod ( 4 ), whereby the connecting rod system ( 4 b ) that moves the push rod ( 4 ) is formed by a connecting rod arm guided in a dummy connector and a connecting rod arm guided out of the dummy connector ( 8 ) by way of a packed gland ( 6 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. Device for influencing the flow in a horizontal connecting pipe ( 1 ) between a coal gasification reactor and a gas cooler/purifier, comprising a Venturi constriction in the flow path of the gas in the pipe ( 1 ), as well as a flow cone positioned on a push rod ( 4 ), the push rod being guided centrally in the pipe, whereby a connecting rod system ( 4 b ) that is guided to the outside is provided to move the push rod ( 4 ), whereby the connecting rod system ( 4 b ) that moves the push rod ( 4 ) is formed by a connecting rod arm guided in a dummy connector and a connecting rod arm guided out of the dummy connector ( 8 ) by way of a packed gland ( 6 ), wherein water injectors ( 10 a , 10 b ) are provided in the flow path of the gas in the pipe ( 1 ) ahead of the Venturi constriction ( 3 ), wherein at least a part of the water injectors ( 10 a , 10 b ) are configured as support elements for the push rod ( 4 ). 2. Device according to claim 1 , wherein the push rod ( 4 ) is provided with a setting device. 3. Device according to claim 2 , wherein the setting device is configured for mechanical and/or electrical and/or hydraulic adjustment of the push rod. 4. Device according to claim 1 , wherein at least two dummy connectors ( 8 ), particularly three dummy connectors ( 8 ), having a connecting rod system that impacts the push rod, are provided on the pipe ( 1 ). 5. Device according to claim 1 , wherein at least the elements that stand in contact with the gas that flows through consist of a corrosion-resistant material or are provided with a corrosion-resistant coating.
