Description

[0001] Petroleum Cokes Manufacturing Equipment [

The present invention relates to a petroleum coke producing apparatus, and more particularly, to a petroleum coke producing apparatus which is capable of preventing drying and pulverizing processes from being overloaded, And more particularly to a petroleum coke producing apparatus capable of being manufactured.

In general, petroleum coke produces kerosene and light oil at atmospheric distillation at 150 ~ 250 ° C and 250 ~ 350 ° C during refining process, and then refines heavy oil fraction through vacuum distillation equipment at the atmospheric distillation residue, It is produced by refining difficult oil through caulking process, and it has the advantage that it has a relatively high calorific value and is cheaper than coal. Therefore, it is mixed with anthracite coal or bituminous coal in a boiler or incinerator using solid fuel, And is used as an adjuvant in a mixed state.

However, in the case of petroleum coke, as shown in FIG. 2, water content is generally 7 to 12%, and the diameter is about 5 cm, which is difficult to use as a direct fuel. Accordingly, various attempts have been made to reduce the moisture content of the petroleum coke and to use the fuel as fuel after the particle size is reduced to a certain level or less.

Korean Patent Registration No. 10-0981627 (filed on Mar. 09, 2010) discloses a powdered petroleum coke for use as an alternative fuel for fuel and a method for producing the powdered petroleum coke, And then dried in a cylindrical rotary dryer in which hot air having a temperature of 100 ° C or more is generated for 20 to 40 minutes and then pulverized and sorted to be 90 to 350 mesh to produce powdered petroleum coke.

However, it is not easy to produce petroleum coke having a certain size and moisture content by a single pulverizing and drying process, and there is a problem that the device is overloaded in the final pulverization process, resulting in frequent breakage, and a single pulverization and drying It is difficult to satisfy the predetermined particle size and moisture content. Therefore, it is necessary to repeat the pulverization and drying process through the screening process. Therefore, the entire manufacturing process is long, There is a problem that overload is caused.

KR 10-0981627 B1 2010. 09. 06.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a system diagram showing an apparatus for producing petroleum coke of the present invention. Fig.
Fig. 2 is a photograph showing petroleum coke having a certain particle size and water content produced during the refining process. Fig.
3 is a photograph showing a powder petroleum coke produced through a petroleum coke producing apparatus of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to an apparatus for producing a petroleum coke which can be used as a fuel aid by pulverizing petroleum coke. The petroleum coke produced in the refining process has a large surface area It is possible to minimize the surface area by reducing the amount of the petroleum coke produced in the refining process so that the water content of the petroleum coke produced in the refining process is reduced to 2 to 3% so as to be suitably used as the fuel aid.

In the present invention, the petroleum coke produced in the refining process is recovered and stored in the collection tank 100 by using a vehicle or the like, and the water content of the petroleum coke is maintained at 7 to 12%. A funnel-shaped hopper 110 may be provided at the lower end of the collection tank 100 and other types of supply structures may be used so that the collected petroleum coke can be easily supplied to the lower end.

Thereafter, the petroleum coke supplied from the collection tank 100 is first crushed through the primary crusher 200. The petroleum coke produced in the refining process has a diameter of about 5 cm and it is necessary to crush the coke to a size less than a certain size. To this end, in the present invention, the naturally dried petroleum coke produced in the refining process is first crushed through the primary crusher 200. The primary pulverizing apparatus 200 may be configured in various forms. For example, in a state where a screw-shaped blade is provided inside a cylindrical shape, the primary pulverizing apparatus 200 is pulverized by the contact between the screw and the cylindrical inner surface Or the blades are rotated through a motor 210 having a constant speed in a state of having a blender-shaped blade at the bottom of the cylindrical space, so that the petroleum coke is firstly pulverized.

Since the petroleum coke supplied at this time maintains a water content of 7 to 12%, the petroleum coke may adhere to the inner surface of the pulverizing blade or the primary pulverizing device during the primary pulverizing process. However, The movement to the primary drying apparatus 300 can be made relatively easily in a situation where it is continuously supplied. According to the present invention, firstly, the petroleum coke produced in the refining process is firstly pulverized by the pulverization process before the drying process, thereby minimizing the scattering of the powder during the pulverization process. The particle size of the petroleum coke is set to 50 to 70 mesh in the first pulverization process through the primary pulverizer 200 and the particle size is gradually reduced in the pulverization process in the subsequent process, Thereby minimizing the load on the device during the process.

The petroleum coke discharged through the primary pulverizing apparatus 200 is supplied to the primary drying apparatus 300 so that the water content of the petroleum coke can be maintained below a predetermined level through the primary drying apparatus 300. The primary drying apparatus 300 may include a heating device 310 such as a hot wire coil to surround the outer surface of the primary drying apparatus 300, It is also possible to continuously supply it to the inside of the apparatus 300.

The primary drying apparatus 300 of the present invention is intended to lower the water content of the primary pulverized petroleum coke to 3 to 5%. To this end, the internal temperature of the primary drying apparatus 300 is 100 to 150 ° C And agitation means (not shown) for agitation is provided so that the petroleum coke can be evenly dried in the primary drying apparatus 300. Generally, the drying process in the primary drying apparatus can be maintained for about 10 to 20 minutes.

The petroleum coke dried at a constant water content through the primary drying apparatus 300 is secondarily pulverized through the secondary pulverizer 400. In the first pulverization process, pulverization was performed while maintaining the water content in the refining process, but in the case of the second pulverization through the second pulverizer 400, the water content was reduced to 3 to 5% The efficiency is further improved and the particle size of the petroleum coke is made to be 70 to 90 mesh through the second pulverization by the secondary pulverizing apparatus 400.

The secondary pulverizing apparatus 400 may have the same structure as that of the primary pulverizing apparatus 200, and the secondary pulverizing is performed while the blades are driven through the rotational force of the motor 400.

After the second pulverization is completed, the petroleum coke is supplied to the second drying apparatus 500. The second drying apparatus 500 is connected to the second pulverizing apparatus 400 through the second pulverizing apparatus 400, So that the petroleum coke can be dried in the process of being transferred to the tank 700. To this end, a heating device 510 such as a hot-wire coil may be provided on the outer surface of the secondary drying apparatus 500 so that the internal temperature of the secondary drying apparatus 500 may be maintained constant, The hot air supply device 530 may be provided to further improve the drying efficiency.

The internal temperature of the secondary drying apparatus 500 is set to 100 to 150 ° C in the same manner as in the primary drying apparatus 300 so that moisture can be effectively removed from the petroleum coke so that the water content can be 2 to 3% The drying process in the secondary drying apparatus 500 is also maintained for about 10 to 20 minutes. In the present invention, the transfer passage 520 is provided so as to smoothly transfer the water from the secondary drying apparatus 500 to the storage tank 700 And the conveyance passage 520 is provided with conveying means such as a conveyor 540 for conveying the secondarily dried petroleum coke.

The drying passage 520 is preferably provided with a heating device 510 so that the drying efficiency can be further improved. By keeping the moving passage 520 in a closed form, So that the situation in which the petroleum coke that satisfies the moisture content as fuel is scattered in the air can be prevented.

The petroleum coke which is dried and transferred through the secondary drying apparatus 500 is transferred to the storage tank 700 and is supplied to the tertiary pulverizing apparatus 600 to satisfy the powder particle size before being stored in the storage tank 700 . The third pulverizing apparatus 600 may be formed in the same manner as the first and second pulverizing apparatuses. However, the number of blades rotated by the motor 610 may be relatively large for the pulverization, The particle size of the petroleum coke through the third milling unit 600 can be 100 to 400 mesh.

In the present invention, the secondary drying apparatus 500 is provided inside the storage tank 700 to solve the problem of powder scattering in the pulverizing process. However, in the secondary drying apparatus 500, And the storage tank 700 may be separated from each other.

In the present invention, a powdered petroleum coke having a particle size of 100 to 400 mesh and a water content of 2 to 3% is prepared through a series of processes from the collection tank 100 to the storage tank 700, The recycle passage 800 may further include a recycle passage 800 for recycling the petroleum coke stored in the storage tank 700 to the secondary pulverizer 400 when the particle size or water content is not satisfied. 1, the recirculation passage 800 is formed in the form of a closed tube to prevent the scattering problem. However, the recirculation passage 800 may be formed to have a structure such as a conveyor or the like, It is possible.

The recycling passage 800 may further include a conveying means such as a screw to allow the petroleum coke to be conveyed to the second crusher 400 through the recycle passage 800, According to the present invention, the petroleum coke may be recycled to the primary pulverizing apparatus 200, but may be transferred to the secondary pulverizing apparatus 400, due to the multi-stage pulverizing and drying process.

FIG. 3 is a photograph showing powdered petroleum coke produced through the apparatus for producing petroleum coke according to the present invention. As shown in FIG. 3, it satisfies a water content of 2 to 3% and a particle size of 100 to 400 mesh.

As described above, according to the present invention, the apparatus for producing petroleum coke is divided into multi-stages to be dried and crushed to reduce the load on the apparatus in each process, and the moisture content and particle size It is possible to easily produce the powdered petroleum coke having the desired particle size, and if the moisture content or particle size after the final grinding can not be satisfied, the drying and pulverization processes are repeatedly performed. However, There is an advantage that can be achieved.
