Definitions

• the invention is directed to a plant for synthesis gas production with a reactor and a gas cooler / cleaner connected in flow therewith.
• One way to produce syngas is to gasify carbonaceous fuels with an oxygen-containing gas. This produces a gas containing carbon monoxide, which can also contain hydrogen if water vapor is added to the starting gas.
• the carbonaceous fuel is finely ground for purposes of synthesis gas production and reacted at high temperature in either air flow or fluidized bed gasification. Due to the manufacturing process, the synthesis gas produced in this way is contaminated with fines and sour gases, so that usually a gas washing process follows. This is carried out in a gas scrubber, where the gas obtained is purified with a chemical or physical washing liquid.
• the connection between the reactor and the gas scrubber is often made by piping, which are long and winding due to the spatial distance from the reactor to the scrubber and where additional thermal expansion must be considered constructive. Finally, a long pipe connection also leads to an increased consumption of material in the construction of the system. For this reason, a shortened design is sought in the construction of pipe joints.
• the object of the invention is to provide a solution with which the most compact possible connection between the reactor on the one hand and the gas cooler or cleaner on the other hand, which are absorbed by different temperatures occurring thermal expansions.
• connection between the reactor and the gas cooler / cleaner is formed by a horizontal connecting piece with a venturi element designed as a throttle element.
• Such a horizontal "short connection" has a number of advantages.
• the gas flow from the reactor can be carried out laterally and guided in the horizontal direction in the device for gas scrubbing.
• a development of the invention provides that the internal throttle element is adjustable.
• a particular embodiment of the invention is that the reactor is placed stationary, wherein the connecting piece is positioned in the region of the fixed point Mantelzarge the reactor, and wherein the gas cooler / cleaner is provided with a horizontal movement ensuring bearings.
• the horizontal connection also has the advantage of less caking, deposits and erosion. It can be provided that the connecting piece is equipped with one or more horizontally lying elements, which can change the flow-through cross section through an external adjusting device, in order to better regulate the different gas flows through a flow-regulating quality of the fine dust separation. to be able to fit.
• the elements can also be configured as adjusting or throttle elements.
• the connecting piece is arranged in the head region of the gas cooler / cleaner, wherein the gas is guided on the shell side and / or centric on or through the laundry basket down to flow through the scrubber against the direction of gravity.
• the invention also provides a process for syngas production, wherein the gas from the reactor is supplied to a gas scrubbing, which is characterized in that the gas is deflected from the direction of gravity upwards and through a horizontal possibly designed as Venturi scrubber tube gas cooler / cleaner in the head region is fed there centric or shell side past a laundry basket or passed through it into the bottom of the gas scrubber and directed against the direction of gravity through the laundry basket and from there further promoted as purified synthesis gas.
• a gas scrubbing which is characterized in that the gas is deflected from the direction of gravity upwards and through a horizontal possibly designed as Venturi scrubber tube gas cooler / cleaner in the head region is fed there centric or shell side past a laundry basket or passed through it into the bottom of the gas scrubber and directed against the direction of gravity through the laundry basket and from there further promoted as purified synthesis gas.

• a coal gasification reactor 1 a coal gasification reaction with the addition of a carbonaceous gas Fuel 2 and an oxygen-containing reaction gas 3 performed.
• the synthesis gas leaves the reaction zone Ia and is cooled down by adding a foreign medium in a cooling zone 4. This gives a cooled synthesis gas 4a.
• Most of the resulting solid is carried out in the reactor downwards 4b.
• the synthesis gas is deflected and passed into a connecting piece 5, which contains a throttle element 6. This is shaped so that it exerts a Venturi effect on the gas flowing through.
• the gas leaves the Venturi scrubber and is fed to a gas scrubber. Behind the outlet of the connecting pipe, it is deflected 6a. It enters an annular space 7a between the gas scrubber wall 7 and the scrubber basket 8 or an inner tube. At the bottom of the gas scrubber, the gas is diverted and flows upwards in the gas scrubber basket 8. In the process, it leaves through a discharge nozzle 9. Purified synthesis gas 10 is obtained.
• the gas scrubber is mounted on roller bearings 7b, 7c in order to absorb thermal expansions of the connecting piece. There may be other devices such as sliding plates od. Like. be provided to absorb the thermal expansion.
