Embodiment 1

[0026] Embodiment 1 of the present invention: a kind of block hole type graphite reboiler, as attached Figure 2-5 Shown, this graphite reboiler comprises graphite block 7, and this graphite block 7 is cylinder structure, is evenly provided with a plurality of material holes 71 that run through the whole cylinder upper and lower surfaces inside graphite block 7, and its inside From left to right, there are evenly arranged a plurality of steam holes 72 passing through the side of the cylinder, and the material holes 71 and the steam holes 72 are arranged alternately and do not communicate with each other. The hole diameter of the material hole 71 and the steam hole 72 is 8-22mm, the wall thickness between the material hole 71 and the steam hole 72 is 3-8mm, the wall thickness between the material holes 71 is 3-8mm, and the wall thickness between the steam holes 72 is 3-8mm. The distance from the material hole 71 outer envelope 75 to the graphite block 7 outer ring body is 20-5...

Embodiment 2

[0064] Embodiment 2 of the present invention: the structure of the graphite reboiler of this embodiment is the same as that of Embodiment 1, and the assembly method is also the same. The difference lies in the impregnation treatment and heat treatment of the graphite parts. In this embodiment, the graphite parts will be prepared with graphite materials: feed pipe 1, lower sealing head 5, graphite block 7, upper graphite block 17, upper sealing head 20 and The discharge pipe 23 is put into the impregnation kettle for phenolic resin impregnation treatment, the impregnation air pressure is 0.5-1.6Mpa, and the impregnation time is 12 hours, and then the impregnated graphite parts are put into the heat treatment kettle for heat treatment, heat treatment The time is 18 hours, and the heat treatment temperature is 150°C. After repeating the stain treatment and heat treatment for 2-4 times, the treated graphite parts are followed up. After impregnation and heat treatment, the strengt...

Embodiment 3

[0065]Embodiment 3 of the present invention: the structure of the graphite reboiler of this embodiment is the same as that of Embodiment 1, and the assembly method is also the same. The difference lies in the impregnation treatment and heat treatment of the graphite parts. In this embodiment, the graphite parts will be prepared with graphite materials: feed pipe 1, lower sealing head 5, graphite block 7, upper graphite block 17, upper sealing head 20 and The discharge pipe 23 is put into the impregnation kettle for phenolic resin impregnation treatment, the impregnation air pressure is 0.5-1.6Mpa, and the impregnation time is 16 hours, and then the impregnated graphite parts are put into the heat treatment kettle for heat treatment, heat treatment The time is 24 hours, and the heat treatment temperature is 190°C. After repeating the stain treatment and heat treatment for 2-4 times, the treated graphite parts are followed up. After impregnation and heat treatment, the strength...

Abstract

The invention discloses a block-hole-type graphite reboiler. The block-hole-type graphite reboiler comprises a graphite block, through material holes are formed in the graphite block from top to bottom, through steam holes are formed in the graphite block from left to right, the material holes and the steam holes are arranged in a staggered mode, and the material holes are not communicated with the steam holes. The material holes and the steam holes are formed in the graphite block in an integrally-formed mode, the material holes and the steam holes are arranged in a staggered mode, the material holes are not communicated with the steam holes, the material holes are spaced from the steam holes by certain distances, and therefore the graphite block is free from leakage between the material holes and the steam holes. The block-hole-type graphite reboiler is good in temperature resistance and corrosion resistant performance, high in strength, good in sealing performance, long in service life, and capable of solving the problem that a conventional block-hole-type graphite reboiler is prone to breakage and leakage and making great contributions to development of the fluorine chemical industry and other petrochemical industries.

Description

technical field [0001] The invention relates to a block-hole graphite reboiler and a manufacturing method thereof, belonging to the technical field of chemical equipment. Background technique [0002] The existing block-hole graphite reboiler has the following problems in the use process: 1. The graphite block is prone to leakage of the material hole and the water hole or the steam hole; 2. The seal between the graphite parts is easy to leak; 3. The seal between the shell and the graphite parts is easy to leak; 4. The graphite block is prone to crack leakage; 5. The graphite block at the air intake part is prone to local high temperature peeling, cracking, damage and leakage. Due to the above problems, the service life of the graphite block hole reboiler in chemical production is not high, the maintenance cost increases, the equipment start-up rate is low, the long-term stable operation of chemical production equipment cannot be guaranteed, and the energy consumption is high...
