Lower chamfer structure at bubble cap section of four-in-one graphite hydrochloric acid synthetic furnace

Abstract

The invention provides a lower chamber structure at a bubble cap section of a four-in-one graphite hydrochloric acid synthetic furnace. The structure comprises a sleeve-shaped bubble cap section graphite jacket, a chamber is formed on the outer side of the lower end of the graphite jacket, and the chamber is 10-20 degrees. According to the lower chamber structure at the bubble cap section of the four-in-one graphite hydrochloric acid synthetic furnace, on the basis of ensuring the strength of the graphite jacket of the bubble cap section, the wall of the graphite jacket is thinned, and meanwhile, flange connection is firm.

Description

technical field [0001] The invention relates to the technical field of tail gas treatment of a graphite synthesis furnace, in particular to a lower chamfered structure of a blister section of a four-in-one graphite hydrochloric acid synthesis furnace. Background technique [0002] The production of industrial hydrochloric acid mainly uses chlorine and hydrogen to burn synthetic hydrogen chloride gas in a synthesis furnace. The synthesis temperature is more than 1500 ° C, so it is necessary to cool down, and the cooled hydrogen chloride gas is then absorbed by dilute hydrochloric acid or water to generate synthetic hydrochloric acid, which includes three processes. : Synthesize - Cool - Absorb. [0003] In conventional production, three sets of equipment are used to complete the above three processes respectively, which has high production cost, low production efficiency and serious waste of raw materials. [0004] The more advanced process is: synthesizing the above three p...
