A vertical pressurized roasting tank

Abstract

The invention discloses a vertical pressurized roasting tank, which comprises a high-pressure tank body, a roasting letter is arranged in the tank body, and a safety valve connecting pipe, a direct-reading pressure gauge connecting pipe, a vacuum pumping connecting pipe, and a nitrogen pressurized connecting pipe are arranged on the tank body , the tank body is composed of an upper tank body and a lower tank body connected together, the upper tank body and the lower tank body are provided with a joint equipment flange for sealing fit, the two equipment flanges are fastened and connected by fasteners, and the lower tank body The bottom of the tank body is provided with a tank body support, the tank body is a water-cooled tank body, and an outer jacket is provided on the upper tank body and the lower tank body, and a water-cooled interlayer is formed between the outer jacket and the tank body. The sleeve is provided with tank cooling water inlet connection and tank cooling water outlet connection, and at least two roasting electrodes are arranged on the side wall of the lower tank body. The vertical pressurized roasting tank has the advantages of high roasting temperature and high roasting pressure. While shortening the roasting time, it can greatly improve the roasting quality and meet the roasting process requirements for producing high-end carbon products.

Description

technical field [0001] The invention relates to a roasting equipment, in particular to a high-pressure roasting tank used for producing carbon products. Background technique [0002] High temperature and pressure roasting is required in the production process of carbon products. The roasting temperature and roasting pressure not only determine the length of roasting time, but also are related to the quality of roasted carbon products. The higher the temperature and pressure of calcination, the shorter the time required for calcination, and the finer particles and better quality of the resulting carbon product. CN 201402042Y discloses an electrode roasting tank. However, since the electrode roasting tank has no cooling structure, the tank body cannot withstand high-temperature roasting, and its roasting temperature is limited, and the pressure that the tank body can withstand is small, which cannot meet The need for pressure roasting. CN 102795620 A discloses a pressurized ...

AI Technical Summary

Problems solved by technology

However, this pressurized roasting furnace can only provide a maximum roasting pressure of 1.2MPa and a roasting temperature of 1250°C. Therefore, it cannot meet the high-temperature and high-pressure roasting environment required for the production of high-end carbon products.
