DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-viscosity fluid supply device for supplying a high-viscosity fluid such as a slurry to a utilization system while controlling a flow rate.

[0002]

2. Description of the Related Art To perform a gasification reaction in a coal gasifier, it is necessary to control the flow rate of slurry such as CWM while continuously supplying the slurry to a burner.

Conventionally, as a high-viscosity fluid supply device such as a slurry, a positive displacement pump such as a Moino pump has been used.

[0004] This volume pump is used in a gasifier or the like.
It is suitable when a high-viscosity fluid is continuously supplied in a large capacity.

[0005]

However, it is difficult to use a large volume pump for a small-capacity test apparatus, for example, even if it is used.

That is, a conventional positive displacement pump for supplying a high-viscosity fluid has a small capacity, for example, several tens kg / Hr.
As described below, there is nothing corresponding to extremely small capacity.

It is an object of the present invention to solve the above-mentioned problems and to provide a high-viscosity fluid supply device capable of continuously supplying a small-capacity high-viscosity fluid.

[0008]

In order to achieve the above object, the present invention is directed to a high-viscosity fluid supply apparatus for continuously supplying a high-viscosity fluid such as a slurry in a small volume. A variable-capacity bag is accommodated in a tank containing a viscous fluid, liquid supply means for continuously supplying a small volume of liquid is connected to the bag, and a discharge line for a high-viscosity fluid is connected to the tank. It is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 10 denotes a slurry, for example, C
A tank for storing a high-viscosity fluid S such as WM, orimulsion fuel, etc., which is provided with end plates 12 and 13 provided above and below a cylinder 11, and sends the high-viscosity fluid to a utilization system through an opening 14 at the top of the tank 10. The discharge line 15 is connected.

In the tank 10, a bag 1 having a variable volume is provided.
6 is accommodated, and a lower portion of the bag body 16 has a supply / drain opening 17 extending to an opening 18 at the bottom of the tank 10 so that the liquid supply means 20 is provided.
Connected to.

The bag body 16 is formed in a cylindrical shape as a whole, and its side surface 21 is formed in a bellows shape.
At the time of inflation so that 2 is in close contact with the bottom of the tank 10,
The upper surface 22 is in close contact with the top in the tank 10.

The liquid supply means 20 includes a liquid supply line 23
Is connected to a small capacity pump 24.

Next, the operation of the present invention will be described.

First, a highly viscous fluid S such as CWM is stored in the tank 10 in a state where the bag 16 is contracted, and a liquid such as water is supplied into the bag 16 by the liquid supply means 20 in this state. By supplying continuously, the bag body 16 is inflated and the tank 1 is inflated.
The high-viscosity fluid S in 0 is supplied to the utilization system from the opening 14 through the discharge line 15.

Since the liquid supply means 20 can continuously supply a liquid such as water which is easy to handle with a small volume, it is possible to extrude the high-viscosity fluid S while controlling the flow rate indirectly.

Therefore, it is possible to continuously supply the high-viscosity fluid S with a small capacity such as 8 kg / Hr.

The volume of the tank 10 may be such that the high-viscosity fluid S can be continuously supplied for approximately one day, but for more continuous supply, the tanks 10 are switched in parallel. The liquid in the bag 16 of the tank 10 that has been supplied while the other is being supplied is drained, and the tank 10 is filled with the high-viscosity fluid S, and this is repeated alternately to supply continuously. It is possible to do.

[0019]

In summary, according to the present invention, a high-viscosity fluid such as a slurry supplied from a tank can be supplied with a small volume while continuously controlling the flow rate. Further, since the flow rate can be controlled by a liquid such as water to be injected into the bag body, the flow rate can be controlled by an inexpensive and unlimited size pump that handles water or the like.
