Wet flue gas desulfurization equipment is widely used to desulfurize flue gas and flue gas discharged from boilers and the like. In wet flue gas desulfurization equipment, a large amount of slurry is used for desulfurization, and in order to effectively utilize the slurry, it is necessary to sufficiently stir the slurry. Therefore, wet flue gas desulfurization equipment has conventionally been equipped with various types of slurry stirring devices. For example, an impeller is rotated from the top of a slurry storage tank by a motor or the like to stir the slurry. Stirring devices and stirring devices in which a horizontal pipe is arranged horizontally at the bottom of a slurry storage tank and which blows air or slurry into the slurry in the storage tank to stir the slurry are widely known. However, it is also known that these conventionally widely known stirring devices are prone to various failures during use. For example, in a stirring device that rotates an impeller in a slurry, there is a problem in that the blades of the impeller are likely to wear out and wear out due to contact with the slurry. Therefore, it is necessary to provide a large opening in the slurry storage tank in order to remove and replace worn and damaged impellers.
Furthermore, depending on the shape of the slurry storage tank, it may be necessary to attach several impellers, which is extremely uneconomical.

になる等の問題点がみられた。 On the other hand, in a stirring device that blows air or slurry into the slurry from a nozzle through a horizontal pipe placed horizontally at the bottom of the slurry storage tank, if the supply of air or slurry is stopped, the slurry will flow into the horizontal pipe at the bottom of the slurry storage tank. Backflow causes solids to accumulate,
Problems such as horizontal piping and horizontally disposed nozzles were blocked by the solids, making effective stirring and mixing impossible.

述の問題点がみられたものである。 FIG. 1 is a perspective view of the conventional agitation device for blowing air or slurry as described above. In many cases of this structure, a horizontal pipe 2 for stirring the slurry is arranged at the bottom of the slurry storage tank 1, which causes the above-mentioned problems.

た。 Figure 2 is a view from the arrow A-A' in Figure 1, and shows horizontal piping 2.
This is an enlarged view of the cross section. As can be seen from Figure 2, the horizontal pipe 2 has holes or nozzles 3.
is formed along the horizontal pipe 2, and air or slurry is ejected from the hole or nozzle 3 to agitate and mix the inside of the slurry storage tank 1.
In the case of a stirring device with such a structure, the slurry storage tank 1
became large in size, and the horizontal pipe 2 disposed at the bottom of the slurry storage tank 1 became long.Therefore, there was a tendency for the horizontal pipe 2 to become clogged with solid matter. In other words, with a structure in which the nozzle 3 is opened in the horizontal pipe 2, there is no problem if air or slurry is ejected from the nozzle 3, but if the supply of air or slurry from the nozzle 3 is stopped, the slurry in the storage tank A portion of the liquid flows back into the horizontal pipe 2. For this reason, the slurry liquid that has flowed back into the horizontal pipe 2 remains in the horizontal pipe 2, and in particular, the solid matter in the slurry liquid flows into the horizontal pipe 2.
Otherwise, the nozzle 3 will be blocked. In this way, in order to prevent blockage of the horizontal pipe 2 and nozzle 3,
It is necessary to increase the supply pressure of air or slurry to be supplied, which has the disadvantage of increasing equipment costs. In addition, if the supply of air or slurry is stopped, solid matter accumulates in the horizontal pipe 2, and when the stirring device is restarted, the horizontal pipe 2 and nozzle 3 become clogged, making stirring and mixing impossible. was often seen.

目的とするものである。 The present invention was proposed in order to solve the problems seen in the prior art described in detail above, and does not require a stirring impeller or the like, and eliminates the problem of clogging of piping systems and nozzles due to slurry and other obstacles. It is an object of the present invention to obtain a novel and improved stirring device for a fluid that can effectively stir and mix a fluid without causing any problems.

A vertical branch pipe is provided, and at least a portion of the supplied air or fluid is jetted out from the lower end opening of the vertical branch pipe to stir and mix the fluid.
The stirring device according to the present invention will be described in further detail below with reference to the accompanying drawings. In the following drawings, the same reference numerals as in FIGS. 1 and 2 above indicate the same parts and equipment, and 1 indicates the slurry storage tank.

が固形物によつて閉塞されることはない。 In the stirring device of the present invention, the main pipe 5 is arranged at the top of the slurry storage tank 1 as shown in FIG. A vertical branch pipe 6 having a lower end opening 7 for stirring the slurry is provided. By blowing or spouting at least a part of the air or slurry supplied through the main pipe 5 from the lower end opening 7 of the vertical branch pipe 6 toward the bottom of the slurry storage tank 1, Stir the fluid,
It is something that is mixed. The above-mentioned <<at least a portion>> means that the air or fluid that is descended through the vertical branch pipe 6 and spouted from the lower end opening 7 does not have to be the entire amount supplied from the main pipe 5, but may vary depending on the situation. This is a description that means that a part of it may be used. As a result, even if the slurry liquid or the like flows back into the lower end opening 7, the resistance when the backflowing slurry liquid is jetted out of the vertical branch pipe 6 is extremely small because it is a downward flow. Even if the supply of slurry is stopped, the solids in the slurry will naturally settle from the lower end opening 7 of the vertical branch pipe 6 into the slurry storage tank 1 from the vertical branch pipe 6 due to its own weight, or lower end opening 7
is not blocked by solids.

There is no need for particularly high supply air or slurry supply pressures, and the stirring and slurry are very effective.
Can be mixed. Further, when implementing the stirring device according to the present invention, it is not necessary to form small holes or nozzles in the piping system, and the implementation structure is simple, so it is extremely advantageous from an economic point of view.
