本発明は、水冷壁で形成されたガス化炉本体を
圧力容器に内蔵させてなる加圧型ガス化装置の改
良に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a pressurized gasifier in which a gasifier main body formed of a water-cooled wall is housed in a pressure vessel.
〔従来の技術〕
石炭ガス化装置において、石炭ガス化炉本体内

状態に対応できず、炉の損傷を招くなどの弊害が
あつた。[Prior Art] In a coal gasifier, the inside of the coal gasifier main body is at high temperature and high pressure, so if a single layer structure is used, an extremely thick furnace wall is required due to the problem of the strength of the furnace wall. However, if the furnace walls are made thicker, the heat dissipation effect cannot be obtained, so the water-cooled walls alone cannot cope with the high temperature inside the furnace, resulting in problems such as damage to the furnace.

を得られるという利点を有していた。 Therefore, conventional methods have been used in which the gasifier main body has a double pipe structure. This double-tube structure consists of a gasifier main body and a pressure vessel that encloses it.The inside of the pressure vessel is kept at a slightly lower pressure than the inside of the gasifier main body, and the high pressure inside the gasifier is It is distributed in two stages between the wall and the pressure vessel wall to accommodate the pressure difference with the outside. This has the advantage that the gasifier main body wall can be made thin and a high heat dissipation effect can be obtained.

However, when using such a double pipe structure, the pressure inside the pressure vessel must be maintained at a certain pressure difference corresponding to the pressure inside the gasifier,
Conventionally, a method has been used in which the produced gas, whose pressure and temperature have been reduced after leaving the gasifier, is compressed again using a compressor or the like, and the produced gas is supplied into the pressure vessel. In this case, in order to maintain a constant pressure difference between the inside of the gasifier and the pressure vessel, it is necessary to change the pressure of the low-temperature generated gas supplied to the inside of the pressure vessel in accordance with pressure fluctuations inside the gasifier. This required a complex structure, including a means to detect the internal pressure of the converter and a means to control the compressibility of the low-temperature product gas supplied. In addition, when using a double-tube structure, there was a problem with the difference in thermal expansion due to the difference in thermal expansion between the gasifier wall and the pressure vessel wall, and a means was needed to solve the distortion caused by this difference in thermal expansion. .

As a result of intensive research to solve these problems, the inventors of the present invention have determined that the differential pressure between the inner and outer surfaces of the gasifier body wall can be used to allow the low-temperature generated gas at the outlet of the heat exchanger to freely flow inside the pressure vessel. It was discovered that the difference in thermal elongation can be absorbed by providing self-balance control by controlling the gasifier, and by providing a structure that seals the high temperature gas in the furnace at the slag discharge port at the bottom of the gasifier main body, and the present invention. This is what we have come to do.

A pressure vessel containing the gasifier body and the heat exchanger, a structure for sealing the gasifier body slag discharge port and the pressure vessel with a water seal, and a structure for sealing the gasifier body slag discharge port and the pressure vessel with a water seal, and a structure for sealing the pressure vessel at the heat exchanger gas outlet. A structure in which an attached gas receiver is provided and a free part is provided between the heat exchanger part and the pressure vessel part so that the generated gas can freely enter and exit, and the heat exchanger with the inside of the pressure vessel of the gasifier main body part. The present invention provides a gasification device characterized by comprising a pressure balance pipe provided so as to communicate the inside of a pressure vessel of a gasification device.

In such a configuration, the low temperature gas at the outlet of the heat exchanger can freely flow inside the pressure vessel through the free part, and the low temperature gas at the outlet of the heat exchanger can freely flow inside the pressure vessel through the balance pipe connecting the pressure vessel of the gasifier main body and the pressure vessel of the heat exchanger. As a result, the low-temperature gas at the outlet of the heat exchanger flows into the pressure vessel of the gasifier main body without any load, making it possible to control the gas pressure within the pressure vessel of the gasifier main body in a self-balancing manner. It is also possible to follow pressure fluctuations inside the gasifier main body. In addition, the structure that seals high-temperature gas with a water seal at the free part of the heat exchanger gas outlet and the slag discharge port of the gasifier body absorbs the difference in thermal expansion between the heat exchanger and the pressure vessel, and between the gasifier body and the pressure vessel. I can do that.
