Alternatively, in the spouted bed gasification method, in which flammable gas is obtained by gasification with air, slag, i.e., molten ash made by melting the ash contained in the coal during the gasification reaction, is deposited on the walls of the gasification reactor and flows down. The slag is then cooled by dripping into a water tank through a small hole called a slag tap, and the dripping slag is allowed to settle at the bottom of the tank, and then discharged from the system through an outlet connected to the bottom of the tank. It is separated and discharged. Figure 1 is a 70-diagram showing the main parts of a conventionally used spouted bed gasifier, where l is a gasification reactor, 2 is a slag tap, 3 is a water tank at the bottom of the gasification reactor, 4 is a hopper, and 5 is a Water supply pipe, 6 is water jet pipe, 7 is drain pipe, 8.9 is valve, 1
0.11 is a partition valve, 12 is a solid-liquid separator, and 13 is a solid transporter. That is, the slag 14 is cooled and solidified in the bottom water tank 3 of the gasification reactor, settles in the hopper 4, and is then discharged.

The frequency of slag discharge was determined. However, with this method, if the type of coal to be treated is the same, it is possible to easily set up an automatic discharge sequence using a timer, etc. However, if the type of coal changes, the amount of ash contained in the coal changes, or the When the rate of slag adhesion in the furnace changes due to changes in conditions, it is difficult to automatically discharge the slag in an optimal manner.

以下、この実施例を用いたスラグの排出方法を原理とと

′で急冷される。急冷されたスラグ14は流動水内15
内を沈降しviL urIl水伯1水内15内られる。The slag discharge method using this embodiment will be explained below along with its principle. Slag 14 produced as a by-product in the gasification reactor 1
is dripped from the slag tap 2 hole to the bottom water tank 3 of the gasification reactor.
’ is rapidly cooled. The rapidly cooled slag 14 is placed in flowing water 15
It settles inside the water and enters the water within 15 minutes.

通る循環系を流れる。The flowing water tank 15 has a water spout pipe 16 at the bottom of the flowing mountain water tank 15.
is provided, water is supplied through the water circulation pipe 17, causing a gentle flow of water from the bottom to the top, and the water jetted from the water spout pipe 16 is drawn up inside the flowing water tank 15.
It flows through the water tank 3' at the bottom of the sigasification reactor, the liquid cyclone/19, and further flows through the circulation system passing through the water pipe 20, the cooler 21, and the water circulation pipe 17.
この際、流動水槽15の底部より供給され流動水槽15
内に水の上昇流れを作る水の上昇流れ速度は、スラグ粒

防止する範囲とする。この水の上昇流れは流動水槽15
内に差圧を生じるが、流動水槽重5の側部には下部に差
圧発振器22、上部に差圧発信器23が設置されており
、流動水槽15内の差圧を測定することができる。At this time, the fluidized water tank 15 is supplied from the bottom of the fluidized water tank 15.
The upward flow velocity of the water that creates the upward flow of water within the slag should be below the terminal velocity relative to the slag particle diameter, and within a range that prevents entrainment of the slag by water. The upward flow of this water is in the fluidized water tank 15.
A differential pressure oscillator 22 is installed at the bottom and a differential pressure transmitter 23 is installed on the side of the fluidized water tank 5, and the differential pressure inside the fluidized water tank 15 can be measured. .
いま、流動水槽15内が水のみ循環している場合の差圧

f(ε)となる。Now, when only water is circulating in the fluidized water tank 15, the differential pressure measured by the differential pressure transmitter 22 is P2, and the differential pressure determined by the pH differential pressure transmitter 23 is P2, but slag is dropped and the slag is deposited. In other words, in a packed bed state, the barley pressure of the differential pressure transmitter 22 is −U, ·Le−f(ε), and in a fluidized bed state, −L, ·(ρ , −ρri・

れは充填層、流動層側れの場合においても成立する。Here, K is a constant, Ull water flow rate, Le/d slag packed bed height, f(ε) is slag filling rate, ρ is slag density, and ρt is water density. Therefore, if the distance t between the two differential pressure outlets 24 and 25 of this differential pressure transmitter 22 is known, the differential pressure at this differential pressure transmitter 22 will be
Irrespective of the state of the fluidized bed, if slag has accumulated above the upper differential pressure outlet 25 of the differential pressure transmitter 22, ρB indicates the density of the slag in the fluidized water tank 15. In other words, if slag has accumulated above the upper differential pressure outlet 25- of the differential pressure transmitter 22, the particle weight per unit height can be determined from the differential pressure signal P of the differential pressure transmitter 22, This holds true even in the case of a packed bed or a fluidized bed.

出が可能である。On the other hand, the differential pressure of the differential pressure transmitter 23 is P2 until the slag has accumulated above the differential pressure outlet 25, but when the slag has accumulated further, the differential pressure increases and reaches P3. When the differential pressure P3 generated by the differential pressure transmitter 23 and the differential pressure P generated by the differential pressure transmitter 22 are equalized, the slag height h in the flowing water tank 15 is h=t+(t
/P) Found by XPs. That is, fluidized water tank 1
The height of the slag deposited in the slag 5 can be constantly detected by the differential pressure transmitters 22 and 23, and it is possible to know the amount of slag dripping regardless of the type of coal or operating conditions. Then, the differential pressure signals from the differential pressure transmitters 22 and 23 are transmitted to the slag discharge control device 2.
Automatic discharge of the slag is possible using the built-in pulp sl, ra/.

。At this stage, when the gasification reaction is started in the gasification reactor 1, the slag 14 drops one after another into the flowing water tank 15, and the differential pressure of the differential pressure transmitter 22 increases accordingly. Thereafter, the differential pressure of the differential pressure transmitter 22 settles down at a constant level, and the differential pressure of the differential pressure transmitter 23 begins to increase. Figure 3 shows the signals from the differential pressure transmitters 22 and 23 during this time, with the horizontal and vertical axes showing the amount of slag dripping and the signal, respectively.
