Problems solved by technology

[0002] The inert circulating gas at the outlet of the pulverized coal bag filter contains a certain amount of moisture and dust. The temperature of the inert circulating gas is between 105-110 ° C. If it directly enters the analytical instrument system, it will affect the online analysis of the oxygen content. Seriously If the oxygen content in the inert circulating gas exceeds the standard and reaches the explosion limit, if it cannot be measured in time and no control measures are taken, the pulverized coal bag filter will explode and the loss will be irreplaceable. estimate

Abstract

The invention relates to decompression refrigeration technologies, especially to an online analysis sample gas air-cooled dedusting and dehumidification device and an application method, and overcomesthe shortcomings of the prior art. Structurally, the upper end of a shell is welded with a matching flange and a blind flange, the middle inside the shell is provided with an air-cooled liquid condensation chamber, an ash and liquid storage chamber is disposed at the lower end inside the shell, and a support is fixed at the bottom of the shell.

Description

technical field [0001] The invention relates to decompression refrigeration technology, in particular to an air-cooled dust removal and dehumidification device for online analysis of sample gas and an application method thereof. Background technique [0002] The inert circulating gas at the outlet of the pulverized coal bag filter contains a certain amount of moisture and dust. The temperature of the inert circulating gas is between 105-110 ° C. If it directly enters the analytical instrument system, it will affect the online analysis of the oxygen content. Seriously If the oxygen content in the inert circulating gas exceeds the standard and reaches the explosion limit, if it cannot be measured in time and control measures are not taken, the pulverized coal bag filter will explode and the loss will be irreplaceable. Estimate. Contents of the invention [0003] The purpose of the present invention is to provide a time-saving and labor-saving on-line air-cooled dust removal...
