| 摘要 |
<p>The invention relates to a device for influencing the flow, particularly in a horizontal connecting pipe (1), between a coal gasification reactor and a gas cooler/purifier, providing a solution having the aim of optionally reducing or blocking the gas flow of a hot syngas without being exposed to the high loads due to corrosiveness and high temperatures while avoiding complex valves or control devices. The aim is achieved by a Venturi constriction in the flow path of the gas in the pipe (1) and a flow cone (4a) positioned on a centrally disposed pusher rod (4), wherein a connecting rod (4b) leading outward is provided for displacing the pusher rod (4), wherein the connecting rod (4b) displacing the pusher rod (4) is formed by a rod arm guided in a dummy socket and a rod arm guided out of the dummy socket (8) by means of a compression gland (6).</p> |
