スラリと置換される。 Wet flue gas desulfurization equipment using the conventional lime plaster method is
As shown in FIG. 1, a large number of small pumps P on the horizontal axis are installed in parallel, and the lime slurry in the absorption liquid tank 1 flows along the arrow, and the amount of exhaust gas in the reaction tower 11 shown by is
SO2 is removed. As a result, the circulating fluid becomes an unsaturated lime and gypsum slurry, a portion of which is withdrawn and replaced with lime slurry.
しかしこの装置では、一度ポンプを停止する
と、ポンプや配管内に石膏スラリが沈積し、再起
動が不可能となるため、モータＭにより駆動され
る撹拌機Ｓを常時運転する必要があつた。 However, in this device, once the pump is stopped, gypsum slurry is deposited inside the pump and piping, making it impossible to restart the pump, so it is necessary to constantly operate the stirrer S driven by the motor M.
このような不具合を解消するための装置として
実公昭54−4050号が提案されている。これを第２
図に示す。この装置の特徴は、
(1) 流水加速板６の設置により適当な噴流を作

る。 Utility Model Publication No. 54-4050 has been proposed as a device to eliminate such problems. This is the second
As shown in the figure. The features of this device are as follows: (1) The installation of a water accelerating plate 6 creates an appropriate jet flow to prevent slurry from settling in the absorption liquid tank 1.
(2) 立軸ポンプ７のため、停止時にポンプ７及び
配管９にスラリが沈積し難しく、又ポンプ７を
再起動する時、ポンプ７による強い旋回流によ
り、ポンプ吸込面７′の下部底面およびその周
辺に沈積したスラリを撹拌除去する。(2) Since the vertical shaft pump 7 is used, it is difficult for slurry to settle in the pump 7 and piping 9 when the pump 7 is stopped, and when the pump 7 is restarted, the strong swirling flow caused by the pump 7 causes damage to the lower bottom of the pump suction surface 7' and its Stir and remove the slurry that has accumulated around it.
などであり、その結果、運転が容易、撹拌機が不
要などの利点がある。As a result, there are advantages such as easy operation and no need for a stirrer.
しかし、ポンプ７の開放点検時、吸収液槽１内
のガス（SO2）が外部に洩れるおそれがある。 However, when the pump 7 is opened and inspected, there is a risk that the gas (SO 2 ) in the absorption liquid tank 1 may leak to the outside.

る湿式排煙脱硫装置に関するものである。 The present invention was developed to solve this problem, and in a wet flue gas desulfurization equipment that circulates the absorption liquid, the absorption liquid tank, which is provided in communication with the side of the opposite column bottom, and the lower end opening are the same. An outer cylinder immersed in the absorption liquid in the absorption liquid tank and separated from the bottom surface of the absorption liquid tank, and attached almost vertically to the top part of the absorption liquid tank so that the soil end opening is opened on the top surface of the top part of the absorption liquid tank; The present invention relates to a wet flue gas desulfurization device characterized by having a vertical shaft pump for circulation of absorption liquid inserted into an outer cylinder and installed to close an opening on the top surface of the top part.

5 is circulated by the pump 7 as shown by the arrow →, and the SO 2 in the flue gas is removed in the reaction tower 11. Around the pump 7, an outer cylinder 16 having an inner diameter larger than the maximum diameter D of the pump is attached to the ceiling 5 of the absorption liquid tank 1, and one end of the outer cylinder 16 is immersed in the lime slurry 15. Further, the outer cylinder 16 and the ceiling 5 are completely sealed, and the gas phase portions 17 and 17' are completely isolated by this seal and the lime slurry liquid 15.

て簡易化することができる。 FIG. 4 shows the apparatus shown in FIG. 3 with the pump removed from the absorption liquid tank 1 and pulled out to the top for inspection. In the case of the device shown in FIG. 2 without the outer cylinder 16, the gas phase part (gas containing SO 2 ) of the absorption liquid tank 1 is opened to the atmosphere during this inspection, and all the gas in this part is released from the outside of the absorption liquid tank 1. Therefore, it was necessary to take measures to prevent the gas from leaking into the atmosphere prior to inspection. On the other hand,
According to the device of the present invention, almost all of the SO 2 gas is removed by simply leaking the gas from the gas phase section 17' in Fig. 3 to the outside.
The pump can be opened and inspected while the contained gas is confined in the absorption liquid tank 1, and inspection work can be extremely simplified.
