れて外筒1や外筒天板1Aには伝達されない。 In the above, when the combustion gas A is supplied to the combustion gas inlet part 6 of the bench lily 4 through the connecting pipe 5 while jetting water or caustic soda liquid from the spray nozzle 7, this combustion gas A is sprayed at the combustion gas inlet part 6. After being cooled and dusted by the liquid ejected from the nozzle 7, it is accelerated while passing through the bench lily 4, and is blown out from the gas discharge end 10 against the bottom plate 9A of the liquid reservoir 9. At this time, since the liquid ejected from the spray nozzle 7 is stored in the liquid reservoir 9, the bench lily 4
The gas blown out from the gas discharge end 10 collides with this stored liquid at high speed and vaporizes or atomizes it. The gas is reversed in flow direction by this collision and comes into contact with the vaporized or atomized liquid, removing any soot that has not yet been removed. At the same time, part of the sulfur dioxide gas in the gas is also absorbed by the droplets and removed. The combustion gas A then passes through the through hole 16
Alternatively, it enters the spiral passages 14 and 15 through the through hole 17. In the spiral passages 14 and 15, a wide-angle circular spray nozzle 18 and an impinging spray nozzle 1 are installed.
Liquid is gushing out from points 9 and 20. Therefore, the combustion gas A entering the spiral passages 14 and 15 first comes into contact at high speed with the droplets sprayed by the wide-angle circular spray nozzle 18 at the start portions 14A and 15A, and then continues into the impinging spray nozzle 19. ,20
contact with fine droplets from. This absorbs and removes sulfur dioxide gas. The gas flowing through the spiral passages 14 and 15 is a high-speed flow, and therefore the fine droplets have a high sulfur dioxide gas absorption efficiency, and the fine droplets move along with the gas through the spiral passages 14 and 15, and absorb gas energy. The centrifugal force of the spiral passages 14, 15
A thin liquid film is formed on the wall surfaces of the spiral strip plates 12 and 13. Therefore, unreacted sulfur dioxide gas in the gas comes into contact with this liquid film and is absorbed.
In this manner, the gas is efficiently desulfurized while passing through the spiral passages 14 and 15 at high speed. The absorption liquid that has absorbed sulfur dioxide gas falls into the lower compartment 8 from the through holes 16 and 17 as needed.
The processing liquid is discharged from the processing liquid through the discharge pipe 28. The gas that has passed through the spiral passages 14 and 15 enters the gas-liquid separation chamber 21 through the through holes 25 and 24 from the center thereof. At this time, the gas is in a swirling flow, so it flows into the gas-liquid separation chamber 21 in the tangential direction, and after the gas flows in, it is discharged from the slit 22 in the tangential direction. At this time, the gas is separated into gas and liquid, and the liquid-separated processing gas B is discharged out of the system from the processing gas discharge pipe 27 through the annular passage 26 at a low speed. Further, the liquid is discharged from the annular passage 26 through a separation liquid discharge pipe 29 as required. In such an action, the gas and processing liquid do not come into direct contact with the outer cylinder 1 and the outer cylinder top plate 1A, but with the corrosion-resistant casing 31. The corrosion-resistant casing 31 undergoes thermal deformation due to contact with liquid or gas, but this is absorbed by the leaf spring 30 and is not transmitted to the outer cylinder 1 or the outer cylinder top plate 1A.

At the same time, it is possible to reduce the overall weight. Furthermore, against thermal deformation such as thermal expansion, the corrosion-resistant casing can be freely deformed via the leaf spring, and the outer cylinder remains at room temperature without being subjected to external force.
