Abstract

The present invention uses an external shaft to pressurize a high-pressure hose with elasticity such that a particle fuel at the inside of the high-pressure hose can be continuously fed to a high-temperature vessel or a high-pressure reactor. Since the particle fuel moves in the high-pressure hose, the particle fuel is not leaking to the outside and can be continuously fed to a high-pressure apparatus in a solid state.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a high-pressure hose and a shaft,

The present invention relates to a high-pressure powder fuel supply apparatus, and more particularly, to an apparatus for continuously supplying pulverized fuel such as pulverized coal or chemical fuel at atmospheric pressure to a high-pressure vessel or a high-pressure reactor.

Integrated Gasification Combined Cycle (IGCC) is a power generation technology that operates a combined power plant using gas after coal is gasified. In other words, after converting coal into synthetic gas mainly composed of hydrogen and carbon monoxide under high temperature and high pressure, it is used as raw material for producing electricity after removing harmful substances such as dust and sulfur compounds and refining to a level similar to natural gas It is eco-friendly power generation technology.

The IGCC is divided into a gasification process that produces syngas from coal, a purification process that produces clean syngas by removing particles and sulfur compounds contained in the syngas, and a combined power generation process that consists of a gas turbine and a steam turbine.

The IGCC power generation system has a higher power generation efficiency than the conventional coal-fired power generation system, and can achieve the effect of reducing the carbon dioxide by about 20%. In addition, it can reduce air pollutants SOx by more than 95% and NOx by 70% or more. Since Korea imports almost all energy sources from overseas, it is inevitable to use economical coal as a fuel for power generation. It is also expected that sustainable environmental regulations, such as IGCC, will continue to be used until at least the mid-21st century.

IGCC technology produces syngas composed mainly of hydrogen and carbon monoxide, separates and purifies hydrogen as necessary, and supplies industrial raw materials such as fertilizers and IGFC (Integrated Gasification Fuel Cell) Is also used as the raw material gas of In addition, IGCC technology can be used to recover sulfur, the main component of environmental pollution in coal, as pure sulfur that can be sold as a useful product.

In a gasification plant such as an IGCC, in particular a dry gasification plant, a storage hopper for storing pulverized fuel such as pulverized coal for continuous supply of pulverized coal, a pulverized fuel which is always operated at a higher pressure than a gasifier or high- A feed hopper that feeds the gasifier in an air stream type, a lock hopper that continuously feeds the powdery fuel of the storage hopper, which is in an atmospheric pressure state, to a pressurized feed hopper while repeating pressurization and normal pressure Pressure powder fuel supply device.

As shown in Fig. 1, in the conventional high-pressure powder feeder, the powdery fuel filled in the feed hopper 20 is converted into the powdery fuel by the nitrogen gas supplied through the high-pressure nitrogen supply valve 23 in the normal operation state, And is continuously supplied to the high-pressure reactor through the transfer line 22 and the transfer line opening / closing valve 21. [ Thereafter, when the powder fuel in the supply hopper 20 is reduced, a refilling process is performed to refill the powder hopper 20 with the powdered fuel.

In the refilling process, the storage hopper opening / closing valve 12 of the storage hopper 10 is opened, and the powdery fuel in the storage hopper 10 is supplied to the lock hopper 14 by a certain amount. When the powder fuel is filled in the lock hopper 14, the storage hopper opening / closing valve 12 is closed and the high-pressure nitrogen supply valve 16 is opened and the nitrogen gas supplied through the high-pressure nitrogen supply valve 16 is supplied to the lock hopper 14 are pressurized to the same pressure as the feed hopper 20. At this time, the differential pressure transmitter 19 measures whether the lock hopper 14 and the supply hopper 20 have reached the same pressure.

When the pressurization of the lock hopper 14 is completed, the high-pressure nitrogen supply valve 16 is closed and the equalizing valve 18 is opened, so that the dome valve 17 is opened, And then refilled with the feed hopper 20. When the powder fuel in the lock hopper 14 is refilled with the supply hopper 20, after the dome valve 17 is closed and the equalizing valve 18 is closed, the vent valve 15 is opened and the internal pressure of the lock hopper 14 Is decompressed. When the inside of the lock hopper 14 is vented through the vent valve 15, the initial state is established and the refilling process of the supply hopper 20 is completed. Thereafter, the refilling process of the powder fuel is continuously repeated at regular time intervals during the normal operation of the high-pressure powder fuel supply device.

However, in the case of such a conventional high-pressure powder feeder, additional equipment such as a pressurizing / decompressing device using high-pressure nitrogen, a high-pressure filter system for filtering vented dust, and a constant pressure / differential pressure gauge And powder fuel injection is performed according to a complicated procedure. In addition, it is impossible to maintain a constant level in the feed hopper due to the injection of powder fuel in a batch rather than a continuous type, and nitrogen gas is continuously used in the process of pressurizing the lock hopper to the same pressure as the feed hopper, When the moisture content is somewhat high, there is a problem that the powder fuel does not come down from the lock hopper to the feed hopper due to the bridging phenomenon (see FIG. 2). The bridging phenomenon is a phenomenon in which the powder fuel in the lock hopper is pressed by moisture and pressure and can not be properly discharged to the outside. There is a case where a plurality of high-pressure powder fuel supply devices are introduced to solve the batch feed problem. However, even in such a case, only pulse-type continuous feed is possible, and the cost for equipment is doubled.

Patent Document 1 improves the conventional lock hopper system and solves the problem that when the powder fuel is supplied from the lock hopper to the feed hopper, it is difficult to measure the feed amount accurately. To this end, Patent Document 1 discloses that a flexible tube is introduced between a lock hopper and a supply hopper to cope with a change in pressure, and is located at an upper portion of the flexible tube by a distance corresponding to the expansion and contraction of the flexible tube during pressurization or evacuation And the lock hopper is moved up and down to accurately measure the weight of the powder sample loaded in each hopper.

Patent Document 2 relates to a solid feed pump having a pump segment in which a plurality of connected cartridges form a closing curve to continuously circulate along the track and the cartridges continue to supply the solid feed . However, the apparatus is not designed to withstand high pressures so as to directly supply powdered fuel directly to the high-temperature, high-pressure gasifier to which the present invention is applied.

Patent Document 3 relates to a device for feeding a solid feed by a circulating-type endless track. This is also not a method of directly supplying powdered fuel to the high-temperature and high-pressure gasifier applied in the present invention, and it is a technology that can be applied simply at normal pressure.

Patent Document 4 relates to a device for supplying a solid feed by rotation of a rotary disk, and is a device using a positive-displacement pump. Currently, the device provides equipment that can be supplied at 68 bar.

Patent Document 5 is a device for supplying a pressurized solid feed using a gap in which a pair of endless orbits are engaged as a pump for providing a high-pressure solid feed.

However, in the case of Patent Documents 4 and 5, there is a problem that some powder fuel leaks when used on a commercial scale for a long period due to a complete sealing problem.

As described above, a technology for improving a part of the lock hopper system around the world has been proposed so far, but there is no commercialization facility for a continuous high-pressure powder fuel supply device which can supply at high pressure without leakage of powder fuel.
