る。The present invention will be described in more detail with reference to the embodiments shown in the drawings. In FIG. 1, 1 is a waste liquid tank in which a waste liquid containing powdery and granular solids is stored, and 2 is a reaction furnace such as an incinerator. The waste liquid is pumped up from the waste liquid tank 1 by a pump or the like and supplied to the reaction furnace 2 through the relay tank 3, and the pipe in the middle has a small diameter.

As shown in FIG. 3, a screen basket 5 for separating solids is installed inside the chamber 4 so that when the waste liquid containing the solids passes through the screen basket 5, the solids are removed. Has become. The periphery of the screen basket 5 is surrounded by a metal mesh 6 having a relatively fine mesh, and the waste liquid containing the solid content flows down from the gap between the mouth of the screen basket 5 and the inner peripheral surface of the chamber 4. To prevent it. Since the metal net 6 has an appropriate elasticity, there is also an advantage that the screen basket 5 can be set in close contact with the inside of the chamber 4 simply by removing the lid 7 of the chamber 4 and pushing in the screen basket 5.

部の固形分を取り出す必要がない。The apparatus for supplying waste liquid containing solids according to the present invention having the above-described structure is provided with a screen basket 5 for separating solids in the middle of a pipe for supplying the waste liquid from the waste liquid tank 1 to the reaction furnace 2. Since the chamber 4 is provided,
The solid content in the waste liquid is separated by the screen basket 5, and only the liquid can be supplied to the reaction furnace 2 via the relay tank 3. Along with this, the solid content gradually accumulates inside the screen basket 5, but the diameter of the conventional strainer was equal to the diameter of the pipe, whereas the screen basket 5 of the present invention has a larger diameter. In addition to having a sufficiently large diameter, the screen basket 5 has a large volume, unlike the strainer, so it is not necessary to frequently take out the solid content inside.

There is no risk of dripping from the gap. Therefore, the solid content can be completely removed. When a large amount of solids are accumulated inside the screen basket 5, the flash nozzle 8
The inside of the chamber 4 may be washed with and the lid 7 may be opened to take out the screen basket 5.

きいものである。As described above, according to the waste liquid supply device containing the solid content of the present invention, the solid content in the waste liquid can be completely removed by the screen basket and supplied to the reaction furnace. Moreover, the frequency of cleaning and replacement due to clogging can be significantly reduced as compared with the conventional strainer. Needless to say, the present invention is not limited to the treatment of radioactive waste liquid, but can be widely applied to the supply of waste liquid containing other solid content. Therefore, the present invention contributes greatly to industrial development as a waste liquid supply device containing solids that solves the conventional problems.
