AI Technical Summary

Problems solved by technology

But adjustments using traditional valves or slide valves require frequent maintenance or are prone to failure because the syngas is hot and contains corrosive components
Conventional valves or slide valves must therefore be replaced after a certain period of time, which leads to higher operating costs and increased maintenance expenditures

Embodiment Construction

[0021] figure 1 A connecting pipe 1 is shown, through which a gas flow 2 is guided from the coal gasification reactor. The gas flow must pass through the narrowing point 3 when passing through the pipe. The tapered part is cut off by a push rod 4 having a thickened part 4a. The guide rod is led to the outside through a shaft seal 6 via a connecting rod 4b having two nodes 5a, 5b, and is driven there by a servo motor 7. The connecting rod 4b is guided through an insulating sleeve 8, which is closed by a closing cover 8a. The gas stream 9 is discharged from the end of the connector connected to the gas scrubber.

[0022] figure 2 A connecting pipe 1 is shown, through which a gas flow 2 is guided from the coal gasification reactor. The gas flow 2 must pass through the narrowing 3 when it is guided through the pipe. The push rod 4 with the thickened part 4a is guided through the tube, and the thickened part is pulled back here. The gas flow can thus pass through the pipe.

Abstract

Device for influencing, in particular, the flow in the horizontal connecting pipe (1) between a coal gasification reactor and a gas cooler / purifier, with which a solution is produced, the purpose of which is to avoid complex valves or regulating devices Where necessary, the flow of hot syngas can be reduced or cut off without being subjected to high loads and high temperatures of corrosive effects. This is achieved by a Venturi constriction in the gas flow path in the pipe (1) and a flow cone (4a) positioned on a centrally arranged push rod (4), wherein the movement of the push rod (4) has a leading External connecting rod (4b), wherein the connecting rod (4b) moving the push rod (4) consists of a lever arm leading into the insulating bushing and a rod leading out of the insulating bushing (8) through the shaft seal (6) arm formation.

Description

Technical field [0001] The invention relates to a device for influencing the flow in a horizontal connecting pipe between a coal gasification reactor and a coal gas cooler / purifier. Background technique [0002] The possibility of synthesis gas production lies in the gasification of pulverized carbon-containing fuel with hydrogen-containing gas. In this respect, a gaseous product consisting essentially of carbon monoxide is obtained. When steam is added to the raw gas, a product gas containing hydrogen is also obtained as a mixture. The synthesis gas thus obtained is used, for example, for the production of ammonia or methanol, but is also suitable for the supply of hydrogen. [0003] A coal gasification reactor is used in the production of synthesis gas through a coal gasification process, which provides synthesis gas mixed with solids and acid gases. For further application, it must be purified so that this syngas is introduced into the device for gas scrubbing. In order to b...
