Embodiment 1

[0039] see Figure 1-Figure 10 As shown, a high-efficiency needle coke production device includes a coking reaction tower 1, and the output end of the coking reaction tower 1 is connected to a purification tower 9 through a pipeline, which is used for thorough purification and fractionation of high-temperature oil and gas to ensure that it enters the fractionation tower 10 There will be no coke particles inside the high-temperature oil and gas. The purification tower 9 is connected to the fractionation tower 10 through pipelines. The bottom of the coking reaction tower 1 is fixed with a discharge pipe 3. The discharge pipe 3 is equipped with a valve opening and closing device, which can be used to control The opening and closing of the discharge pipe 3, the top of the coking reaction tower 1 is provided with a feed pipe 11, the feed pipe 11 is connected to the fractionation tower 10, and is used to transport the high-temperature oil and gas and the refined coal tar soft pitch m...

Embodiment 2

[0042] see figure 1 , Figure 5-Figure 10 As shown, the end of the gas guide pipe 2 away from the coking reaction tower 1 is fixedly installed with a purification mechanism 5. When the high-temperature oil and gas inside the coking reaction tower 1 are exported, a large amount of coke particles are contained in the escaping high-temperature oil and gas, which is likely to affect the stability of the equipment. The purification mechanism 5 is designed to perform preliminary purification treatment on the escaping high-temperature oil and gas through physical methods, thereby reducing the pressure of the rear transportation pipeline and purification tower 9 for slag removal and fractionation. One side of the purification mechanism 5 is symmetrically arranged with the air guide pipe 2 pipeline, the pipeline is used to connect the purification mechanism 5 and the purification tower 9, the bottom end of the purification mechanism 5 is connected with a return pipe 4, and one end of t...

Embodiment 3

[0044] see figure 1 with Figure 7-Figure 10 As shown, the end of the gas guide pipe 2 away from the coking reaction tower 1 is fixedly installed with a purification mechanism 5. When the high-temperature oil and gas inside the coking reaction tower 1 are exported, a large amount of coke particles are contained in the escaping high-temperature oil and gas, which is likely to affect the stability of the equipment. The purification mechanism 5 is designed to perform preliminary purification treatment on the escaping high-temperature oil and gas through physical methods, thereby reducing the pressure of the rear transportation pipeline and purification tower 9 for slag removal and fractionation.

Abstract

The invention relates to the technical field of needle coke production, which is used to solve the problems that coke particles are easy to block equipment pipelines and uneven temperature during the coking process, and specifically relates to a high-efficiency needle coke production device and method, including coking reaction tower, the output end of the coking reaction tower is connected to a purification tower through a pipeline, the side wall of the coking reaction tower is provided with an air guide pipe, and a discharge mechanism is arranged inside the discharge pipe; in the present invention, high-temperature oil and gas are discharged in the coking reaction tower, When circulating in the purification tower and fractionation tower, each time it is exported from the coking reaction tower, it will go through the preliminary purification of the purification mechanism, thereby reducing the purification pressure of the purification tower and ensuring that the high-temperature oil and gas in the fractionation tower will not contain coke particles. At the same time, due to the existence of the discharge mechanism, the raw materials move slowly during the internal coking reaction, which increases the uniformity of temperature, and the discharge speed is increased through the assistance of the discharge mechanism, preventing the occurrence of blockage of the discharge pipe.

Description

technical field [0001] The invention relates to the technical field of needle coke production, in particular to a high-efficiency needle coke production device and method. Background technique [0002] Needle coke is a high-quality variety that is vigorously developed among carbon materials. Its appearance is a silver-gray porous solid with metallic luster. The needle coke produced can be divided into petroleum series and coal series according to the raw materials used. Raw materials for high-end carbon products such as high-power electrodes, special carbon materials, carbon fibers and their composite materials, especially in the manufacture of high-power and ultra-high-power electrodes, needle coke is the only high-quality material, made of needle coke The advanced graphite electrode has the advantages of strong thermal shock resistance, high mechanical strength, good oxidation performance, low electrode consumption and large allowable current density. [0003] The patent ...
