Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] figure 1 It schematically shows the stepped sealing structure between graphite blocks of a four-in-one graphite synthesis furnace according to an embodiment of the present invention.

[0014] Such as figure 1 As shown, the stepped sealing structure between the graphite blocks of the four-in-one graphite synthesis furnace of the present invention is a sealed and leak-proof structure between two adjacent graphite blocks in the graphite synthesis furnace.

[0015] In this embodiment of the present invention, two adjacent graphite blocks are defined as a first graphite block 11 and a second graphite block 12 . As shown in the figure, the connection surfaces of the first graphite block 11 and the second graphite block 12 are respectively set as N (N≥1) level stepped surfaces 13 that cooperate with each other, and in this embodimen...

Abstract

The invention provides a sealing structure for steps among graphite blocks in a four-in-one graphite synthetic furnace. The sealing structure comprises a first graphite block and a second graphite block adjacent to the first graphite block, wherein mutually matched N step surfaces are respectively arranged on a connecting surface of the first graphite block and the second graphite block, and the N is not less than 1; the first graphite block and the second graphite block are mutually buckled via the step surfaces. The sealing structure for the steps among the graphite blocks in the four-in-one graphite synthetic furnace has a simple structure and a good sealing effect, and effectively prevents fluid and gas leakage.

Description

technical field [0001] The invention relates to the technical field of graphite synthesis furnace sealing, in particular to a stepped sealing structure between graphite blocks of a four-in-one graphite synthesis furnace. Background technique [0002] The production of industrial hydrochloric acid mainly uses chlorine and hydrogen to burn and synthesize hydrogen chloride gas in a synthesis furnace. The synthesis temperature is greater than 1500°C, so it is necessary to cool down. The cooled hydrogen chloride gas is then absorbed with dilute hydrochloric acid or water to generate synthetic hydrochloric acid, which includes three processes. : Synthesis - Cooling - Absorption. [0003] Conventional production uses three sets of equipment 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: the above three processes of synthesis - cooling - absorpti...
