High temperature roasting furnace of hydrogenation catalyst

Abstract

The invention relates to a high temperature roasting furnace of a hydrogenation catalyst. The roasting furnace comprises a barrel body and a transmission system connected with the barrel body, wherein the barrel body is supported by a supporting system, and the interior of the barrel body is divided into a preheating section, a roasting section and a cooling section; one end of the barrel body is connected with a material feeding system, and the other end of the barrel body is connected with a material discharging system; a heating system is arranged outside the preheating section; a finned shoveling plate, a sectioned material baffle and a helical material baffle located at the material feeding system end are arranged in the barrel body; an anti-radiation plate is arranged between the roasting section and the cooling section. The high temperature roasting furnace has the advantages of guaranteeing uniform heating of a material, reducing the energy consumption and the like.

Description

technical field [0001] The invention relates to a roasting furnace, in particular to a high-temperature roasting furnace for a hydrogenation catalyst. Background technique [0002] Roasting is a key process for the preparation of hydrogenation catalysts. Through high-temperature dehydration and heat treatment, the catalysts can generate metal oxides, change the distribution of pores, form active phases, and stabilize their mechanical strength. The calcination temperature of the hydrocracking catalyst is as high as 900°C to 1000°C, and the calcination time is about 5 hours or more. Existing equipment similar to high-temperature roasters has the following limitations during use: [0003] ① Ordinary copying boards and baffle boards fall off under high temperature temperature difference and pressure; [0004] ② Ordinary copying boards will destroy materials under high temperature conditions; [0005] ③Similar equipment has no anti-radiation panels and consumes a lot of energy...
