When direction is formed, with helicla flute 28 to compared with the case where different direction in direction of circling round of exhaust gas e is formed, convolution can be reduced
Decaying.
Perhaps helicla flute 28 can only form one or be formed side by side more than two slot 24,26.In addition, slot 24,26
Or helicla flute 28 is formed in at least inner peripheral surface 12a in the inner wall of absorbent tower body 12, but other than inner peripheral surface 12a,
Such as the bottom surface of absorbent tower body 12 can also be formed in as shown in Figure 2.In addition, when the axial direction from absorbent tower body 12
When observation, these slots whole region in the circumferential direction of inner peripheral surface 12a is formed.In addition, slot 24,26 or the expectation tool of helicla flute 28
There are the depth of the liquid film for the cleaning solution Cs for being formed in inner peripheral surface 12a or more, the depth of such as 5mm or more.
Fig. 6 is the perspective view for schematically showing absorbent tower body 12.As shown in fig. 6, bumps involved in an embodiment
18 (18d) are included the multiple protrusions 30 (the first protrusion) dispersedly formed on circumferential surface 12a.When the axis from absorbent tower body 12
To when observation, the whole region in the circumferential direction of inner peripheral surface 12a of protrusion 30 is arranged.
It can be increased by forming the bumps 18 (18d) including multiple protrusions 30 along inner peripheral surface according to the embodiment
The contact area that the cleaning solution Cs of 12a is contacted with exhaust gas e, thereby, it is possible to improve the cleaning efficiency of exhaust gas.
Multiple protrusions 30 are not overlapped, and need dispersedly to configure, and thereby, it is possible to form the bumps 18 that can increase contact area
(18d)。
In one embodiment, it needs not influence emission-control equipment in the crushing increase of the exhaust gas e by inner space s
In the range of 10 operating, height of the protrusion 30 away from inner peripheral surface 12a and interval between protrusion 30 etc. are set.
As shown in fig. 6, in one embodiment, multiple protrusions 30 to be formed in the central axis relative to absorbent tower body 12
The position of line O point-symmetrically.As a result, on the cross section of inner space s, it can equably increase contact of the cleaning solution with exhaust gas
Area.
It should be noted that protrusion 30 both can be simultaneously integrally formed when manufacturing inner peripheral surface 12a with inner peripheral surface 12a,
Can also be separately manufactured with inner peripheral surface 12a, and inner peripheral surface 12a is installed on after manufacturing inner peripheral surface 12a.
In one embodiment, by the inner surface of absorbent tower body 12 (for accurate, in Fig. 1 and Fig. 2, demisting
The inner surface whole region of the inner peripheral surface and bottom surface including absorbent tower body 12 in the lower zone of device 22) bumps 1
8 are set as occlusion rate 0% the case where being all not provided with, will be set as occlusion rate the case where inner surface whole region is provided with bumps 18
100%.In this case, it is desirable to make 50% or less occlusion rate.If occlusion rate is more than 50%, in absorbent tower body 12
The pressure loss in portion, exhaust gas e becomes larger, the rotating force decaying of exhaust gas e.
In one embodiment, as shown in Fig. 2, exhaust gas introduction part 16 is by the waste gas ingress pipe that connect with absorbent tower body 12
It constitutes, the interconnecting piece of the waste gas ingress pipe connecting with absorbent tower body 12 is made of the straight sections 32 of rectilinear form.Such as Fig. 2 institute
Show, straight sections 32 are configured along the tangential direction of the outer peripheral surface of absorbent tower body 12, and the exhaust gas e imported from straight sections 32 is in inside
Swirling flow fs is formed in the s of space.In addition, being dispersedly configured with multiple protrusions 34 (the second protrusion) in the inner peripheral surface of straight sections 32.
In the case where the upstream side of straight sections 32 has bent portion etc., the exhaust gas for being flowed into straight sections 32 is easy to produce partially
Stream.According to the embodiment, since the inner peripheral surface in straight sections 32 is dispersedly provided with multiple protrusions 34, it is able to suppress
The bias current of the exhaust gas e flowed in straight sections 32.The SO that thereby, it is possible to inhibit to include in the exhaust gas e flowed in straight sections 32X
Etc. the concentration distribution of harmful components and the deviation of velocity flow profile, make exhaust gas e as uniform fluid import inner space s.Cause
This, can increase the attaching space of the exhaust gas and cleaning solution in the s of inner space, and thereby, it is possible to improve connecing for exhaust gas and cleaning solution
Touching property, and can be improved the removal rate of the harmful components in exhaust gas.
Multiple protrusions 34 are not overlapped and dispersedly configure.Thereby, it is possible to improve the inclined of the exhaust gas e flowed in straight sections 32
Flow inhibitory effect.In addition, it is necessary to not influence the operating of emission-control equipment 10 in the crushing increase by the exhaust gas e of straight sections 32
In the range of, height of the protrusion 34 away from inner peripheral surface 12a and interval between protrusion 34 etc. are set.
Protrusion 34 is desirably formed in whole region in the circumferential direction of the inner peripheral surface of straight sections 32.In addition, protrusion 34 both can be
It is simultaneously integrally formed when manufacturing the inner peripheral surface of straight sections 32 with the inner peripheral surface, can also be separately manufactured with the inner peripheral surface, and
The inner peripheral surface is installed on after manufacturing the inner peripheral surface.
In one embodiment, it will be set as occluding the case where one protrusion 34 of inner peripheral surface of straight sections 32 is all not provided with
Rate 0% will be set as occlusion rate 100% the case where the inner peripheral surface whole region of straight sections 32 is provided with protrusion 34.In the situation
Under, it is expected that making 50% or less occlusion rate.If occlusion rate is more than 50%, although under the action of protrusion 34, SOXDeng it is harmful at
The deviation of the concentration distribution and velocity flow profile divided can be inhibited, but since the pressure loss becomes larger, there are exhaust gas e's
A possibility that flow velocity reduces and the rotating force inside absorbent tower body reduces.
