Description of the Related Art Abundant ultra-heavy oil (commonly referred to as Orinoco tar) is buried in a basin called Orinoco Belt located in the northern basin of the Orinoco River in Venezuela, South America. This ultra-heavy oil has the property of solidifying at room temperature, and has a problem in handling. However, recently, a technique for emulsifying orinocotar has been developed and the problem in handling has been solved, so that it is used as a fuel for thermal power plants and the like.

ルを付加したものが一般的に使用されている。By the way, in a thermal power plant, powdery combustion ash generated when fuel such as heavy oil is burned is usually collected by an electric dust collector. When the collected combustion ash is transported to a processing plant, the volume is reduced by humidifying and kneading with a humidifying kneader to granulate, and then packed in a container bag or the like and transported.
This volume reduction reduces transport efficiency. As a humidifying / kneading machine, a screw conveyor having a spray nozzle for humidification is generally used.

う問題があった。However, powdery combustion ash produced by burning a fuel obtained by emulsifying this orinocotal is
It has a property that when it is kneaded with humidification, it generates heat and is easily solidified when it is cooled, and further, when it is excessively humidified, its tackiness is remarkably increased and it is easily adhered to the inside of the casing of the humidification kneader or the screw conveyor to be solidified. This property of the humidified combustion ash is remarkable when the operation of the humidified kneader is stopped, and when the humidified combustion ash remaining in the humidified kneader has a large degree of humidification, it may be attached in about 1 minute. Therefore, when the operation of the humidification kneader is stopped, humidified combustion ash adheres and solidifies on the screw conveyor etc. in the humidification kneader, and the problem that the screw conveyor does not move when the humidification kneader is operated next often occurs. was there.

There was a problem that it occurred. The present invention has been made in view of such circumstances, when the humidification kneader that handles combustion ash having a property of easily adhering and solidifying is stopped for a short time, the humidification combustion ash does not adhere and solidify in the humidification kneader. It is an object of the present invention to provide a method of operating a humidifying and kneading machine that can be prevented.

In the method of operating the humidification kneader for granulating, before stopping the operation of the humidification kneader, the combustion ash is supplied to the humidification kneader in a state where the humidification is stopped and remains in the humidification kneader. It is characterized in that it is discharged from the humidifying and kneading machine while being mixed with the humidified and kneaded humidified combustion ash.

Was fed to the humidifying kneader and was discharged while being mixed with the humidified combustion ash remaining in the humidifying kneader. This allows
Combustion ash with a small amount of water and difficult to adhere to remains in the humidification kneader. Therefore, the humidified combustion ash becomes difficult to adhere to and solidify on the kneading means of the humidifying and kneading machine, such as a screw conveyor, and when the humidifying and kneading machine is restarted, the combustion ash covering the humidified combustion ash serves as a slip agent. As a result, the rotation resistance of the screw conveyor is reduced, so that smooth operation restart can be performed.

焼灰をスクレッパー等で削り取らなくてはならない。A fixed amount of the combustion ash in the hopper tank 12 is supplied to the humidifying and kneading machine 18 by the table feeder 14. The combustion ash supplied to the humidifying / kneading machine 18 is normally sprayed with water from a spray pipe 58 arranged on the supply port 32 side, and is kneaded by the screw conveyor 28 while being discharged from the discharge port 3
4 is transported. The humidification rate to the combustion ash (weight of added water / weight of added water + weight of combustion ash) was set to about 25%. As a result, the powdery combustion ash supplied to the humidifying and kneading machine 18 is granulated (average particle size of about 7 mm), and the volume of the powdery combustion ash before humidifying and kneading is about 1 /
Volume is reduced to 5. Reduced volume of humidified combustion ash is about 1m 3
The container bag 22 having a sufficient capacity is filled and transported to a processing factory (not shown). This humidified combustion ash container bag 2
In the filling operation of No. 2, the operation of the humidifying and kneading machine 18 is stopped for several minutes until the filled container bag 22 is removed from the filling shooter 24 and a new container bag 22 is attached to the filling shooter 24. . When the operation of the humidifying and kneading machine 18 is stopped for a short time, the humidified and kneaded humidified combustion ash remaining in the humidifying and kneading machine 18 adheres to the screw blades 38 and the rotary shaft 40 to be solidified, and the screw conveyor 28 does not move when the operation is restarted. Such troubles will occur. Therefore, every time a trouble occurs, the top plate of the humidifying / kneading machine 18 must be opened and the humidified combustion ash adhering to the inside of the humidifying / kneading machine 18 must be scraped off by a scraper or the like.

灰の平均水分を下げるので、付着しにくくなる。Therefore, in the operating method of the present invention, when the operation of the humidifying / kneading machine 18 is stopped, the supply of water from the water supply device 62 is stopped, for example, for about 1 minute, and then the humidifying / kneading machine 1 is operated.
8 and the table feeder 14 are stopped,
Combustion ash (dry powdery ash) was supplied to the humidification kneader 18 with the humidification stopped, and discharged while mixing with the humidified combustion ash remaining in the humidification kneader 18. As a result, the combustion ash that has a small amount of water and does not easily adhere to the humidifying and kneading machine 18
The small amount of the humidified combustion ash that remains in the interior and easily solidifies to cover the humidified combustion ash. Therefore, the humidified combustion ash hardly adheres to the screw blade 38 and the rotary shaft 40 and solidifies, and
When the humidifying / kneading machine 18 is restarted, the combustion ash that surrounds the humidified combustion ash acts as a slipping agent and the screw conveyor 2
Since the rotation resistance of No. 8 is lowered, it is possible to smoothly restart the operation. Further, since the combustion ash having a low water content is mixed with the humidification combustion ash remaining in the humidification kneader, the average water content of the humidification combustion ash is lowered, so that the adhesion becomes difficult.

できる。By the way, when the operation of the humidifying / kneading machine 18 is finished on the day and stopped until the next day for about one night, water is sprayed from all the spray pipes to wash the inside of the humidifying / kneading machine. In this embodiment, the timer mechanism manages the time difference between the operation / stop of the table feeder 14, the humidifying / kneading machine 18, and the water supply device 62. However, the combustion supplied from the hopper tank 12 to the humidifying / kneading machine 18 is performed. A measuring means for measuring the supply amount of ash may be provided so that the supply amount of the normal combustion ash can be increased by a predetermined amount immediately before the operation of the humidifying and kneading machine 18 is stopped. Further, a timer mechanism and the measuring means may be combined. Further, in the present embodiment, the screw conveyor type humidifying and kneading machine was described as an example of continuously supplying and continuously discharging combustion ash, but the operating method of the present invention may be any kneading means, and further a batch type humidifying and kneading machine. Can also be applied to.

At the time of re-operation, the combustion ash covering the humidified combustion ash acts as a slipping agent to reduce the rotation resistance of the screw, so that smooth operation restart can be performed.
