Description

DEVICE FOR REMOVAL OF SLAG "

The present invention relates to a slag removing apparatus, and more particularly, to an apparatus for removing slag accumulated in a gasifier.

Due to the limited resources and the importance of environmental protection, renewable energy is becoming a next-generation energy resource. Generally, renewable energy refers to renewable energy utilizing natural environment such as wind, tidal, hydro, and solar.

Among these renewable energy sources, gasification technology is a technology that gasifies fossil fuels such as coal and petroleum by using oxygen and steam to produce syngas, and refines it to convert it into advanced energy such as electricity, chemicals, liquid fuel, hydrogen.

This gasification technology has been attracting attention because it is eco-friendly and can utilize the existing facilities while achieving higher energy utilization efficiency than the conventional combustion method. In the gasification technology, there is a typical Integrated Gasification Combined Cycle (IGCC).

In addition, the slag scraper 120 may be formed of a material to which the Curie temperature corresponding to the melting temperature of the raw material is applied. At this time, when the temperature of the slag scraper 120 is lower than the Curie temperature, the slag scraper 120 has magnetism and the magnetism disappears when the temperature rises.

 The slag scraping part 120 can be moved up and down by this property and the repulsive force by the magnetic part described below. The up and down movement of the slag scraper 120 will be described when describing the operation and effects of the slag removing apparatus 100 to be described later.

At this time, the second magnetic portion 142 may be provided with an electromagnet whose current direction is adjusted so that repulsive force acts on the first magnetic portion 141.

One side of the slag discharge unit 110 may be provided with a support unit 160 for supporting the slag scraping unit 120 so that the slag scraper 120 is not separated from the slag discharge unit 110 when the slag scraper 120 is moved.

The support part 110 is fixed to one side of the slag discharge part 110 and supports the slag scraper part 120 when the slag scraper part 120 moves up and down.

When the slag scraping part 120 is lifted by the restoring force of the elastic part 150 provided at the lower end of the second magnetic part 142, .

The support portion 160 prevents the first member from descending below the support portion 160 by the support portion 160 when the slag scraping portion 120 is lowered by the repulsive force of the magnetic portion.

A distance sensor (not shown) may be mounted on one side of the first magnetic portion 141 or the second magnetic portion 142 to detect a distance between the first magnetic portion 141 and the second magnetic portion 142 170 may be mounted. The distance sensor 170 may be provided with a sensor capable of detecting a distance by light.

The distance sensor 170 senses the proximity of the first magnetic portion 141 and the second magnetic portion 142 so that the control portion 180 described below controls the operation of the heating portion 130 .

The slag scraping unit 120 may further include a heating unit 130 for melting the slag moved to the lower end of the slag discharging unit 110. A part of the slag passes through the slag discharging part 110 and is discharged to the cooling tank 220 by the descent of the slag scraping part 120 and the remaining part of the slag is attached to the inner wall surface of the slag discharging part 110 do.

Accordingly, the heating unit 130 applies heat to the semi-solid slag attached to the inner wall surface of the lower end of the slag discharging unit 110, thereby causing the slag to melt and flow out to the cooling tank 220 .

At this time, it is preferable that the heating unit 130 melts the slag by spraying a flame toward the outer wall of the lower end of the slag discharging unit 110. Only the slag may be melted by spraying the flame directly toward the slag and the high temperature heat may be conducted through the outer wall of the slag discharging part 110 to melt the slag attached to the inner wall surface of the slag discharging part.

The control unit 180 may control the operation of the heating unit 130 according to the upward and downward movement of the slag scraper 120.

Hereinafter, the operation and effect of the slag removing apparatus 100 according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3. FIG.

2 (a), 2 (b), 2 (c) and 2 (d) are views showing a continuous operation state of the slag removing apparatus, After the state of the slag discharging unit 110 has passed, the slag discharging unit 110 recirculates to the state shown in FIG. 2 (a), and the slag attached to the inner wall surface of the slag discharging unit 110 is removed through this process.

2 (a), the temperature of the slag scraper 120 is lowest before the heating unit 130 is operated, and the temperature of the slag scraper 120 is lower than the temperature of the slag scraper 120, At this time, the temperature of the slag scraper 120 is lower than the Curie temperature, and the third member 123 of the slag scraper 120 has the strongest magnetism.

 As a result, the magnetic force of the third member 123, which is the internal material of the second magnetic portion 142, becomes the strongest, so that the magnetic flux density of the second magnetic portion 142 is the highest and the intensity of the magnetic force of the second magnetic portion 142 Is in its largest state.

 That is, the state shown in FIG. 2 (a) occurs when the magnetic force of the second magnetic portion 142 is the strongest, and is generated between the first magnetic portion 141 and the second magnetic portion 142 The repulsive force is the largest.

At this time, the elastic part 150 is provided so as to have a resilience such that the restoring force of the elastic part 150 is smaller than the repulsive force. The slag scraping part 120 is located at the bottom of the slag discharging part 110 do.

When the slag scraper 120 is positioned at the lowest end of the slag discharging unit 110, the distance between the first magnetic part 141 and the first magnetic part 141 is detected by the distance sensor 170 attached to one side of the magnetic part, The distance between the two magnetic portions 142 is detected as being the greatest.

The control unit 180 controls the heating unit 130 to heat the slag discharging unit 110 when it is determined that the first magnetic unit and the second magnetic unit are at a predetermined distance or more, ).

2 (a), when the heating unit 130 is operated, the flame in the heating unit 130 heats the slag discharging unit 110. At this time, the heating unit 130 heats the slag discharging unit 110 at a temperature higher than the melting temperature of the slag, and the slag discharging unit 110 is installed in the slag discharging unit 110 Heat is transferred to the slag, and the slag melts and is discharged to the outside.

Accordingly, the molten slag flows in the direction of gravity along the wall surface of the slag discharging part 110 and flows out to the cooling bath.

On the other hand, heat generated in the slag discharging unit 110 is conducted so that the temperature of the slag scraping unit 120 also rises above the melting temperature of the slag. When the temperature of the slag scraper 120 rises above the melting temperature of the fossil raw material, which is the Curie temperature of the slag scraper 120, the magnetism of the slag scraper 120 gradually disappears. As a result, the strength of the magnetic force of the second magnetic portion 142 decreases as the magnetic force of the third member 123 located inside the second magnetic portion 142 disappears.

2 (b), as the temperature of the third member 123 rises, the intensity of the magnetic force of the second magnetic portion 142 gradually decreases to decrease the strength of the first magnetic portion 141 The strength of the repulsive force between the second magnetic portions 142 gradually decreases and the slag scraping portion 120 gradually moves to the upper end of the slag discharging portion 110 by the restoring force of the elastic portion 150 do.

2 (c), the strength of the magnetic force of the second magnetic part is the weakest, and the restoring force of the elastic part 150 causes the slag scraping part 120 to move to the top of the slag discharging part 110 .

2 (b), when the slag scraper 120 moves to the upper end of the slag discharging unit 110, the distance sensor 170 detects the distance between the first magnetic portion 141 And the second magnetic portion 142 are within a predetermined distance and transmits the sensed result to the controller 180. The controller 180 stops the operation of the heating portion 130. [

The temperature of the slag scraping unit 120 gradually decreases and the temperature of the slag scraping unit 120 decreases as the operation of the heating unit 130 stops. 123) Also, the temperature is lowered below the Curie temperature, and magnetism is generated again.

2 (c), the temperature of the third member 123, which has risen above the Curie temperature, begins to drop, and the magnetic force of the second magnetic portion 142 is weakest, So that the magnetic force is increased.

2 (d), the repulsive force between the first magnetic portion 141 and the second magnetic portion 142 increases, and this repulsive force is greater than the restoring force of the elastic portion 150 So that the slag scraper 120 moves to the lower end.

2 (a), FIG. 2 (b), FIG. 2 (c), and FIG. 2 (b) after the slag scraper 120 has moved to the lower end d of the slag discharging unit 110 while being circulated.

When the slag remover 100 is to be stopped, the operation of the heating unit 130 is stopped so that a repulsive force between the first magnetic portion 141 and the second magnetic portion 142 is applied to the elastic portion Can be stopped in a state similar to the state shown in Fig. 2 (a) while maintaining the state of being larger than the restoring force by the elastic member 150.

2 (c), 2 (d) and 3, in order to examine the discharge process of the slag according to the movement of the slag scraper,

When the slag scraping part 120 is positioned at the upper end of the slag discharging part 110, the slag flowing down to the inner wall of the slag discharging part 110 passes through the opening 121a of the first member 121 The slag is attached to the inner wall of the slag discharging part 110 and the slag is removed by the first member 121 of the slag scraping part 120 while the slag scraping part 120 is lowered, As shown in FIG.

Since the second member 122 is a tubular member extending from the first member 121, the slag flowing down from the inner wall of the slag discharging unit 120 can flow through the opening of the first member 121 The slag discharging unit 110 is installed at a lower end of the slag discharging unit 110 so that the heating unit 130 is melted in operation and is discharged to the outside of the slag discharging unit 110 .

2 (a) and 2 (b), when the slag scraper 120 is positioned at the lower end of the slag discharge unit 110 or at the lower end of the slag discharge unit 110, The slag is discharged from the slag tap 111 to the slag discharging part 110 even when the slag discharging part 110 ascends.

At this time, when the slag scraping part 120 rises and the slag rises to pass through the opening 121a of the first member 121, since the slag is in a fluid state in a semi-solid melting state, The slag discharging unit 110 is attached to the inner wall of the slag discharging unit 110.

Even in this case, the slag scraper 120 moves up to the lower end of the slag discharge unit 110 while descending, and then removed.

That is, the slag scraping part 120 may be formed in the inside of the slag discharging part 110 according to the magnitude of the magnetic force varying with the temperature, using a member whose restoring force of the elastic part 150 and Curie temperature are adjusted to the melting temperature of the fossil raw material. And the slag attached to the inner wall of the slag discharging part 110 is moved downwardly of the slag discharging part 110 when the slag scraping part 120 is lowered to partially move the slag discharging part 110 The slag is discharged to the outside of the slag discharging part 110, and a part of the slag is heated by the heating part 130 and discharged to the outside of the slag discharging part 110 in a molten state.
