Needle-shaped calcined petroleum coke production technology and calcining furnace for technology

Abstract

The invention provides a needle-shaped calcined petroleum coke production technology and a calcining furnace for the technology and in particular relates to the technical field of petroleum coke production. The calcining furnace is a pot type calcining furnace and comprises a furnace body and a flue; a plurality of groups of pot bodies which are distributed in parallel are arranged in the furnacebody along the length direction; each group of the pot body is composed of two pot bodies which are distributed along the width direction of the furnace body; the furnace body is internally provided with a plurality of heating walls; the adjacent two groups of the pot bodies are separated through the heating walls; one heating wall is arranged in each of a front wall and a rear wall; each heatingwall is internally and sequentially provided with a volatilization layer composed of a fire channel, a calcining layer and a cooling layer, which are communicated with one another; each volatilizationlayer is communicated with a natural gas pipeline; the flue comprises a plurality of flue gas secondary channels and a flue gas general channel; and each cooling layer is communicated with the flue gas general channel through the flue gas secondary channels. According to the calcining furnace, natural gas is introduced into the pot type calcining furnace and is mixed with volatile components in needle-shaped calcined petroleum coke to be combusted, so that the temperature of the calcining layer reaches 1400 DEG C and the true density of a finished product reaches 2.15.

Description

technical field [0001] The invention belongs to the technical field of petroleum coke production, and in particular relates to a needle-shaped calcined petroleum coke production process and a calciner for production thereof. Background technique [0002] Needle-shaped calcined petroleum coke is a high-end electrode material. When it is calcined in a rotary kiln, the burning loss is large. When it is calcined in a pot calciner, the volatile matter in it cannot be burned at 1400 degrees Celsius, and the calcining effect is not good. The true density of the finished product can only reach 2.13. [0003] Therefore be badly in need of a kind of needle-shaped calcined petroleum coke production technology and its production calciner that can solve existing problems. Contents of the invention [0004] The object of the present invention is to provide a production process of needle-shaped calcined petroleum coke and a calciner for its production, use the tank-type calciner of the ...
