Problems solved by technology

When there is a lot of water in the syngas, the chilling water level in the chilling chamber will continue to drop, which will eventually lead to system load reduction and affect the production intensity of the device.
At the same time, a large amount of chilled liquid is brought to the subsequent washing tower, which will cause the liquid level of the washing tower to rise, unstable operation, etc., and affect the operation of the subsequent process

Embodiment Construction

[0015] As shown in Figure 1, the present invention includes: a support plate 1, a water separation baffle plate 2, a downcomer 3 and a furnace shell 4, the support plate 1 is placed horizontally in the annular space between the downcomer 3 and the furnace shell 4, and is fixed Water separation baffle action. The two sides of the support plate 1 are respectively fixed with the downcomer 3 and the furnace shell 4, the inner side of the support plate 1 is welded on the downcomer 3, the outer side is welded on the shell 4, and the water separation baffle 2 is fixed on the support plate 1 to support The plate 1 and the water separation baffle 2 are respectively 3-6 layers.

[0016] As shown in Figure 1, the support plate 1 is an annular flat plate formed by welding together 4-8 metal plates (metal plates such as steel plates, stainless diamond plates, and iron plates), and the angle of each metal plate is 360 degrees / ( 4-8) block arrangement, in this embodiment, 6 steel plates are...

Abstract

The invention discloses a reducing device of synthetic gas with water content, which comprises the following parts: falling pipe, furnace case, support board and water separating baffle on the support board, wherein the support board is placed in the ring-shaped space between falling pipe and furnace case with two sides fixing the falling pipe and furnace case separately; the invention removes clock lid and rising pipe from traditional structure, which makes synthetic gas rise between falling pipe and furnace bulk; the synthetic gas reduces the flow speed through separating baffle, which reduces the liquid carrying content.

Description

technical field [0001] The invention relates to a device for reducing the amount of water carried in the synthesis gas of a gasification furnace. technical background [0002] Coal gasification technology is a technology that can efficiently and cleanly utilize coal. Coal is gasified to obtain crude synthesis gas, and the process gas obtained after subsequent treatment of the crude synthesis gas can be used as raw material gas for synthetic ammonia or other chemical products. [0003] The pulverized coal is incompletely burned in the gasification section to generate high-temperature synthesis gas and slag, and then enters the quenching section. The role of the chilling section is to chill the high-temperature syngas and slag, and then separate the gas and slag through a water bath and deash the syngas. [0004] In Texaco's existing water bath system, there are downcomers, bell jars and upcomers. After being cooled and absorbing saturated water vapor, the syngas exits the ...
