ために近年では、消石灰の略飽和溶液を製造する
装置の出現をみるに至つた。 Slaked lime was often injected into purified water as a 10-15% slurry, but this method had disadvantages such as the accumulation of sludge in water treatment ponds. For this reason, in recent years, we have seen the emergence of equipment for producing substantially saturated solutions of slaked lime.

Water is supplied from 4 to the lower part of the tank via a control valve 5 and a flow meter 6, and is stirred by a stirrer 7 installed at the lower part of the dissolving tank 1 to dissolve the slaked lime. The solution was flowing out.

However, in the production of the above-mentioned conventional slaked lime solution,
Two devices are required: a stirrer to promote the solution of slaked lime and a water supply device for dissolved water. Furthermore, since the dissolved water is supplied to one place in the dissolution tank, the flow of slaked lime particles becomes uneven, leading to dissolution. In order to do this, it was necessary to operate the stirrer strongly, and the power required to operate the stirrer (continuous operation) was also large.

In the present invention with the above configuration, when slaked lime particles are put into the tank and dissolved water is supplied to the rotary water supply device, the dissolved water is injected from the injection nozzle of the horizontal rotating pipe, and at the same time, the horizontal rotating pipe rotates, and the dissolved water is fed into the tank. The slaked lime particle layer at the bottom is stirred and fluidized to dissolve the slaked lime particles, resulting in a substantially saturated solution of slaked lime that flows out from the solution outlet at the top of the tank.
本考案の一実施例を第１図及び第２図を参照し
ながら以下に説明する。
An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
貯留を兼ねる溶解槽１の上部には溶液流出部８

ンには回転式給水装置９が配備されている。 There is a solution outflow part 8 at the top of the dissolution tank 1 which also serves as storage.
A rotary water supply device 9 is provided in the slaked lime slurry zone in the lower part of the dissolution tank 1.

こともできる。 As shown in FIG. 2, the rotary water supply device 9 includes a suitable number of injection nozzles 10, preferably in which a horizontal rotary tube 11 disposed on one side communicates with a vertical rotary tube 12. Dissolve pipe 12 Water supply pipe 4
The horizontal rotary tube 11 is rotated by the reaction force of the injection of dissolved water from the injection nozzle 10. The horizontal rotary tube 11 may be formed in one stage, but may also be connected to the vertical rotary tube 12 in multiple vertical stages.
また、溶解水供給管４には、調節弁５、流量計

機である。 Further, the dissolved water supply pipe 4 is provided with a control valve 5 and a flow meter 6. In the figure, 2 is a hopper for slaked lime particles, and 3 is a feeder for slaked lime particles in the hopper 2.
しかして、消石灰粒子の一定量を、ホツパー２

攪拌、流動されて溶解し、略飽和溶液となつて上
部の溶液流出部８から槽外へ流出する。 Then, a certain amount of slaked lime particles was transferred to the hopper 2.
The feeder 3 supplies dissolved water (tap water, etc.) from the dissolved water supply pipe 4 to the dissolution tank 1 through the control valve 5.
The water is supplied to the rotary water supply device 9 via the flow meter 7.
The dissolved water is injected from the injection nozzle 10 of the horizontal rotary tube 11 of the rotary water supply device 9, and at the same time, the horizontal rotary tube 11 is rotated by the reaction force, and the slaked lime particles are stirred and fluidized and dissolved, and are almost saturated. It becomes a solution and flows out of the tank from the solution outflow section 8 at the top.
このようにして、消石灰の略飽和溶液が得られ

給水量が、先に槽内に供給した消石灰量に見合つ
た量に達した時にはその給水を停止し、再度消石
灰粒子を供給したのち上記のような溶解を行う。 In this way, a substantially saturated solution of slaked lime is obtained, but when the amount of dissolved water supplied, measured and integrated by the flow meter 6, reaches an amount commensurate with the amount of slaked lime previously supplied into the tank, After stopping the water supply and supplying slaked lime particles again, dissolution as described above is carried out.

る。 By the way, based on the operating results of conventional equipment, in order to continuously obtain a substantially saturated solution with a constant concentration from the top of the dissolution tank, the rising flow rate of the dissolved water at the bottom of the dissolution tank should be set at 0.01~
It has been found that the slaked lime particles can be made to flow by setting the speed in the range of 0.06 m/min and rotating the stirrer installed at the bottom at a low circumferential speed of 1 m/sec or less.
