Description

Crude synthesis gas purifying separator

Technical Field

The utility model belongs to the technical field of chemical equipment, and relates to a crude synthesis gas purifying separator.

Background

In the coal chemical production, 2-5 mg/Nm of coarse synthesis gas of the coal gasification device is entrained ³ In order to prevent subsequent dust build-up from clogging the pipes and valves, the gas stream needs to be cleaned when entering the interface. It is common practice to pass the stream of raw synthesis gas through a gas-liquid separator and to separate it by gravity sedimentation, which generally removes part of the large-particle solid particles, but it is disadvantageous mainly in that it is difficult to completely remove the solid particles, especially small-particle dust, from the gas. Along with the operation of the device, small-particle dust is gradually accumulated, so that the phenomenon of pipeline blockage is caused, and the normal production of the device is influenced.
