Description of the invention (7) In order to form a slanted face in the direction of the above parallel flow, the treatment liquid s does not stay in this part and flows down, and exhaust 01 Parallel flow can proceed smoothly. ; Moreover, the exhaust gas G1 and the treatment liquid S are in contact with the two side portions 22a, 22b of the inverted V-shaped piece 22, the inverted V-shaped piece 22 will be slightly shaken, so the place when the parallel flow * _ liquid solution S It has good contact with Paiguan G1 and can give full play to the absorption performance of sulfur oxides, etc. At the same time, the crystals of calcium sulfite and the like generated by the Ca in the M treatment solution S become difficult to precipitate in the inverted V-shaped sheet 22, the treatment The vortex of the liquid S rarely forms, so that the crystals can be inhibited from becoming scale and consolidating in the inverted V-shaped sheet 22. In particular, the treatment liquid S and the exhaust gas G1 shake the vibration of the inverted v-shaped piece 22 by virtue of the scraping force when it hits the inverted v-shaped piece 22, and then the wind pressure when passing through the gap D, so that the treatment liquid S does not become a film, and forms fine droplets by the vibration and flew away from the two sides 22a, 22b of the inverted V-shaped piece 22, and the contact with the exhaust gas G1 remains good, which can be reliably prevented The scale adheres to both side portions 22a and 22b of the inverted V-shaped piece 22. Also * the exhaust gas G1 and the treatment liquid S are initially peeled off the scale attached to the inner wall of the absorption tower 2 over time, even if the M-shaped V-shaped piece 22 falls, but by the shaking of the inverted V-shaped piece 22 The gap D can make it fall down, so the scale will not block the mesh of the gap D. Moreover, even if the lotus transfer is continued for a long time, the amount of scale adhesion to the inverted V-shaped sheet 22 is very small, so the scale can be easily removed by gently knocking down the V-shaped sheet 22 during maintenance work. The shaped piece 22 can be unloaded and supported by the supporting shaft 23, so instead of performing the knocking operation, the inverted V-shaped piece 22 can be replaced. This paper standard can be used in China National Standards (CNS) Α4 specification (210Χ297 mm)- 10-II Mmwn I-1-- — ^ 1 1 ^ 1 m In · (Read the precautions on the back before filling out this page) A7 B7 printed by the Beigong Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Description of invention (8 ) For maintenance purposes, it can be changed to be safe and secure. However, the absorption tower 2 'of this kind generally takes the encounter velocity of the exhaust gas G1 passing through the gap D as U, and the change in exhaust load (gas volume) causes the loss of force ΛΡ to be approximately the passing velocity U is multiplied by 2 to increase or decrease (curve b of Figure 6). Therefore, when the gaps D of the inverted V-shaped pieces 22 are matched with the maximum load in a fixed state where the exhaust load is reduced to 1/2, the passing speed U is reduced to 1/2, and the energy loss ΔP The spray efficiency of the treatment liquid S reduced to 1/4 'becomes very bad. In order to travel this way, when the exhaust load is reduced, in order to exert the effective fogging effect of the treatment liquid S, the system must be prepared to supply air at 4 times the pressure at the maximum load. From this point, the two side portions 22a, 22bM of the inverted V-shaped piece 22 may have the same length. However, as shown in FIG. 4, the two side portions 22a, 22b are different in length from each other to form a comparative clam. In other words, if the lengths of the two side portions 22a and 22b of the inverted V-shaped piece 22 are different, when the exhaust load increases, the dynamic scraping of the long side portion 22b of the inverted V-shaped piece 22 increases, so the inverted V shape As shown in Fig. 5 from the position of the solid line to the position of the key line, the piece 22 'is greatly shaken and displaced at the short side portion 22a, and the gap widens from D to D1. As a result, the speed U passing through the gap D1 is reduced, while the change in the exhaust load can reduce the change in pressure loss (curve a of Fig. 6). In addition, in order to smoothly move the inverted V-shaped piece 22, the top of the inverted V-shaped piece 22, as shown in FIG. good. Secondly, the exhaust gas G2 and the treatment liquid S desulfurized in the absorption tower 2 as described above are for the gas-liquid separation tower 1 »the introduction unit 3 is fed by the tangential square and the exhaust gas is used.

Invention description (9) G2 is rotating in the gas-liquid separation tower 1 while increasing the centrifugal force The droplets are separated and discharged from the chimney 16 to the outside. In other words, the gas-liquid separation column 1 can directly separate gas and liquid without using a built-in separator or the like, so that the device configuration can be simplified. In addition, the gas-liquid separation column 1 is provided with a tobacco chrysanthemum 16, which can achieve a smaller size than the previous device configuration. * In addition to suppressing the construction cost of the equipment, it can also achieve the effective use of equipment land. In addition, in the above-mentioned embodiment, the parallel flow promotion member row 21 made of a plurality of inverted V-shaped pieces 22 is arranged at a position where the exhaust gas G1 and the processing liquid SM flow in the longitudinal direction, but as shown in FIG. 7, The above-mentioned example 21 of the co-flow promotion member may be provided at a position where the exhaust gas G1 and the processing liquid SM flow in the lateral direction. In addition, FIG. 7 is a schematic diagram of a state in which the exhaust gas G1 and the treatment liquid SM are operated in parallel. In addition, the above-mentioned embodiment of K is described using the inverted V-shaped piece 22 as a cocurrent promoting member. However, as shown in FIG. 8, the configuration of the M inverted U-shaped piece 31 may be sufficient. In this case, the bent portion 31a of the inverted U-shaped piece 31 becomes a face portion inclined to the downstream side in the cocurrent direction. The processing liquid S flowing down the curved portion 31a is easier to form a film than the two side portions 22a and 22b of the inverted V-shaped piece 22. However, as described above, the pressure of the processing liquid S and the exhaust gas G1 is inverted to U The shape piece 31 is vibrated and shaken in the shape of M. As in the case of using the inverted V-shaped piece 22, the adhesion of scale can be effectively suppressed. Furthermore, the above description of K uses Ca (OH) 2 as a salty reagent, but various calcium compounds or magnesium compounds such as CaC03, MgO, Mg (OH) 2, and MgC03 may also be used. In addition, if necessary, the formation of scale is generally difficult to be a problem, and it is no problem to use salty reagents such as NaOH and Ha2C03.

Description of the invention (10) Contain sulfur oxides such as SOZ as the main object, but not limited to this, including reacting with the above salty reagents and being marred The other harmful components that can be removed by the method are not bad. Next, in order to investigate the desulfurization efficiency, a test under K was performed using the parallel flow promotion member arrays 21A and 21B according to the above-mentioned real cell morphology. As shown in FIG. 9, on the inner side of the absorption tower 2, the two sides of the regular triangle serving as the co-current promoting member are respectively equivalent to the two side portions 22a, 22b of the inverted V-shaped piece 22, which is the same as FIGS. 1 and 2. The situation is configured and assembled as two upper and lower M sections 21A and 21B. Most of the gaps between the inverted V-shaped pieces 22 are D, and the opening ratio for the entire wide gap D inside the absorption tower 2 is 30S !. In the absorption tower 2, the S02 exhaust gas containing 210PP1Π from the upper opening is introduced at a predetermined gas volume (3,900m3 / hour, 3,600m3 / hour and 2,000m3 / hour), here, by installing in the cocurrent The nipple above the promotion member 22 will be used as a saline reagent treatment solution containing Ha2C03, sprayed at a fixed flow rate of K15 tons / hour and discharged from the lower opening after Mae treatment. After this treatment, the amount of exhaust gas S02 (ppm) was measured to calculate the desulfurization efficiency. The Ministry of Economic Affairs, Central Bureau of Standards and Staff ’s Consumer Cooperative printed these results, the parallel flow promotion member row 21A ΔP (pressure loss) in the upper stage, and the parallel flow promotion member row 2 1 B △ P (M force loss) in the lower stage 'Are shown in Table 1 below. From the results in Table 1, it can be understood that, by using the co-flow promotion member of the specific configuration described above, it is understandable that a very excellent desulfurization effect can be obtained in a wide range of gas volumes including S02 exhaust gas. 13-(Please read the precautions on the back before filling in this page) This paper scale is applicable to Chinese national standards (CNS> Λ4 specifications (210Χ29?
