Description

Wet tank module and wet scrubber including the same The present invention relates to a wet tank module and a wet scrubber including the same, and more specifically, to a wet tank module for a scrubber for receiving harmful gas, removing harmful components, and discharging it, and a wet scrubber including the same. Dust collectors for treating dust and powder generated in various industries and plants are applied to coal-fired power plants, downstream of desulfurization facilities, downstream of industrial boilers and BC-Oil boilers, plasticizer coating, downstream of incinerators, combustion processes, pulp and paper manufacturing processes, steel mill processes, and other processes where fine dust is generated. The initial model of the aforementioned dust collector is a dry electrostatic precipitator. Due to its operating principle, the dry dust collector has the disadvantage of low dust collection efficiency caused by the re-dispersion of powder continuously accumulated on the dust collection surface (ground), and also has an operational disadvantage requiring the removal of accumulated powder by periodically applying physical impact, such as tapping. At this time, a method is used in which water is supplied to the dust collection surface to drop the powder into a tank (water tank) provided on the lower side, and corona discharge occurs from the discharge electrode to the dust collection surface due to the potential difference between the discharge electrode, which applies high voltage from the power supply, and the dust collection surface, which is grounded and has a potential level of zero. At this time, as the exhaust gas passes through the discharge region between the discharge electrode and the dust collection surface, powder (particle, dust) is collected on the dust collection surface. At this time, the dust collection performance varies depending on the resistivity of the powder contained in the exhaust gas. Meanwhile, in the case of such an electrostatic precipitator, the volume was increased by widening the distance between the discharge electrode and the dust collection surface to increase the flow rate of the waste gas to be treated in order to increase the dust collection capacity; however, in this case, there is a problem in that smooth dust collection is not performed because the discharge performance is lowered due to the potential difference being maintained as a result of the increased distance between the discharge electrode and the dust collection surface. In other words, while increasing the capacity of the dust collector is essential as the flow rate of the waste gas to be treated generated upstream of the dust collector increases, there is a problem in that the flow rate of the waste gas to be treated cannot be increased because, in the case of electrostatic precipitators, maintaining a certain distance between the discharge electrode and the dust collection surface is essential due to the dust collection method. Accordingly, a wet scrubber equipped with multiple electrostatic precipitators was developed, but the tank for installing multiple electrostatic precipitators and reactors was not modularized, so the equipment configuration is complex and there is a problem that it is difficult to manufacture the entire wet scrubber in a modularized manner. FIG. 1 is a perspective view showing a wet scrubber according to the present invention. FIG. 2 is a perspective view showing another embodiment of a wet scrubber according to the present invention. FIG. 3 is a perspective view showing the appearance of a wet tank module according to the present invention. Figure 4 is a drawing showing the interior of a wet tank module according to Figure 3. The wet tank module according to the present invention and the wet scrubber including the same will be described in detail with reference to the attached drawings as follows. A wet tank module according to the present invention includes, as shown in FIG. 1, a chamber (100) forming an internal space (S); and a partition (200) that partitions the internal space (S) corresponding to the reactor (10) and a plurality of dust collectors (20). In addition, the wet tank module according to the present invention may further include a frame part (300) installed on the inner wall of the chamber (100) to form the edges of the first space (S1) and the second space (S2) together with the inner wall of the chamber (100) on a planar surface. The above chamber (100) can be configured in various ways as a structure forming an internal space (S). That is, the chamber (100) may be configured to form an internal space (S), and to install a reactor (10), a plurality of dust collectors (20) and a pump (30), and at the same time, to store water used in the internal space (S). To this end, the chamber (100) may include a chamber body (110) with an open top and a cover part (120) installed on the open top of the chamber body (110) to form a sealed internal space (S) together wi
