Problems solved by technology

In the hydrogenation unit of the prior art, the reaction feed heating furnace and the reboiler at the bottom of the fractionation tower are often arranged together, and both share a set of waste heat recovery system, which makes the overall hydrogenation unit occupy a large area and heat dissipation area. The one-time investment cost is high, but the heating efficiency is not high; therefore, the present invention designs a hydrogenation device with a two-in-one integrated structure. Effectively reduce the one-time investment of the furnace and improve the efficiency of the furnace, with good application prospects and market value

Embodiment 1

[0012] The main structure of the structure-integrated hydrogenation device involved in this embodiment includes a burner 1, a radiation furnace tube 2 of a reboiler at the bottom of a fractionation tower, a radiation chamber 3, a radiation furnace tube 4 of a reaction feeding furnace, and a radiation furnace tube of a reaction feeding furnace Pipe frame 5, lining 6, fractionation tower bottom reboiler radiant furnace tube hook 7, steel structure frame 8, fractionation tower bottom reboiler convection furnace tube 9, convection chamber 10, chimney 11 and oil transfer line 12, inner space The inner middle and lower ends of the overall hydrogenation device with a three-dimensional structure are separated to form 2-8 radiation chambers 3, and the central vertical direction of the radiation chamber 3 is equipped with a tube frame 5 for the radiation furnace tube of the reaction feeding furnace, and the tube rack 5 for the radiation furnace tube of the reaction feeding furnace Interc...

Embodiment 2

[0016] The structure-integrated hydrogenation device involved in this embodiment provides a further preferred technical solution on the same basis as in Embodiment 1: the radiation furnace tubes 2 of the reboiler furnace at the bottom of the fractionation tower on both sides of the radiation chamber 3 can be separated by one The burners 1 are evenly arranged, so that the radiant furnace tube 2 of the reboiler bottom of the fractionating tower mainly receives the radiant heat from the nearest burner 1, so as to realize the flexible and convenient adjustment of the medium in the radiant furnace tube 2 of the reboiler bottom of the fractionating tower absorbed heat load.

Abstract

The invention belongs to the technical field of heating equipment in the petrochemical industry, and relates to an integrated hydrogenation device. The hydrogenation device is characterized in that a plurality of radiation chambers are formed in the middle lower end in the hydrogenation device; reaction feeding furnace radiation furnace pipes which are arranged in parallel at intervals and communicated with each other are arranged in the center of each radiation chamber through reaction feeding furnace radiation furnace pipe frames; combustors fixed at the bottom end of the radiation chamber are arranged on the two sides of each reaction feeding furnace radiation furnace pipe at an equal interval; the periphery of the hydrogenation device is formed by combining steel structure frames; linings are arranged on the inner sides of the steel structure frames; fractionating tower bottom reboiler furnace radiation furnace pipes communicated with each other are fixedly hung on the linings on the inner and outer sides of the upper end of the radiation chamber through fractionating tower bottom reboiler furnace radiation furnace pipe hooks respectively; a convection chamber for arranging fractionating tower bottom reboiler furnace convection furnace pipes inside is butted with the middle of the top end of the upper part of the whole radiation chamber in a communicated manner; the top end of the convection chamber is butted with a chimney. The device is simple in structure, reliable in principle, scientific and reasonable in design, low in manufacturing cost and environment-friendly.

Description

Technical field: [0001] The invention belongs to the technical field of heating equipment in the petrochemical industry, and specifically relates to a structure-integrated hydrogenation device, which adopts an integrated design mode and combines a traditional independent reaction feeding furnace and a fractionating tower bottom reboiler into one to form a Hydrogenation unit with overall integrated structure. Background technique: [0002] With the progress of heavy and inferior crude oil and advanced processing of crude oil in the world, more and more people pay attention to hydrogenation units. At present, hydrocracking, hydrodesulfurization or denitrogenation, and hydrotreating are widely used in the oil refining industry. Or hydrofining and other devices, according to the needs of the process, the hydrogenation device is generally equipped with two heating furnaces, a reaction feed heating furnace and a fractionating tower bottom reboiler. Reactive feed heating furnaces ...
