Abstract

The invention discloses a petroleum coke pot typed calciner cooling water jacket, comprising a step-one heat exchanging device which is used for enclosing a high-temperature material passage; the step-one heat exchanging device comprises a ring-shaped upper container which is provided with a water outlet, a ring-shaped lower container which is provided with a water inlet, a plurality of heat exchanging pipes which are fixedly connected with the upper container and the lower container and communicated with each other respectively, a heat guiding baffle which is fixedly connected between two adjacent heat exchanging pipes; the high-temperature material passage which is enclosed by the step-one heat exchanging device is internally provided with a step-two heat exchanging device. The cooling water sleeve has good rigidity, and is not easy to generate thermal deformation; furthermore, the heat exchanging area is large and the cooling and heat exchanging effect is good; by increasing the step-two heat exchanging device, the uniformity of the temperature inside the whole passage is greatly improved, the temperature of the outgoing material is lowered from 300 DEG C to 150 DEG C; with thereduction of the temperature of the material, the service life of the material drainage valve is prolonged, and the malfunction rate of the material drainage system is reduced.

Description

technical field [0001] The invention relates to the technical field of petroleum coke can-type calcination furnaces, in particular to a cooling heat exchange device for cooling high-temperature materials used in petroleum coke can-type calcination furnaces. Background technique [0002] Petroleum coke is a black or dark gray hard solid petroleum product with a metallic luster and a porous appearance. It is a carbon body composed of tiny graphite crystals in the form of granular, columnar or needle-shaped. The main uses of petroleum coke are prebaked anodes and anode pastes used in electrolytic aluminum, carbon additives in the carbon industry, graphite electrodes, silicon in the smelting industry, and fuels. In order to make petroleum coke (green coke) suitable for the requirements of graphite electrodes for steelmaking or anode paste (melting electrodes) for aluminum and magnesium production, the raw coke must be calcined. The calcination temperature is generally around 13...
