Description

本発明は、ガスの吸収装置における気液接触用充填材に関する。   The present invention relates to a gas-liquid contact filler in a gas absorber.

ガス吸収装置の充填塔に充填される気液接触用充填材として、例えば下記特許文献１及び２に記載されている。このような気液接触用充填材は、充填塔に多数投入されるものであって、一般的に、気液接触用充填材は、充填塔に充填した際に自重による変形が少なく、かつ単位体積当たりの表面積ができる限り大きいことが要求される。   For example, Patent Documents 1 and 2 listed below describe gas-liquid contact fillers that are packed in a packed tower of a gas absorption device. A large number of such gas-liquid contact fillers are charged into the packed tower. Generally, the gas-liquid contact filler is less deformed by its own weight when packed in the packed tower, and the unit The surface area per volume is required to be as large as possible.

特許文献１の気液接触用充填材は、鞍形フラップに４つの大開口部と、各大開口部の相互間に小開口部を設け、大開口部には、鞍形フラップの表裏に交互にそれぞれ円錐筒を設け、小開口部にも、鞍形フラップの表裏に交互にそれぞれ小型円錐筒を設けている。特許文献１では、板状の支持翼を小型円錐筒にすることにより、強度を増大させて変形を抑え、さらに１個当たりの表面積を増大させている。しかしながら、鞍形フラップの前端部、後端部および左右両端部において、外側から内側にかかる応力に弱く、強度に改善の余地がある。   The gas-liquid contact filler of Patent Document 1 is provided with four large openings in a bowl-shaped flap and small openings between each large opening, and the large openings alternately on the front and back of the bowl-shaped flap. Each is provided with a conical cylinder, and small conical cylinders are alternately provided on the front and back sides of the hook-shaped flap in the small opening. In Patent Document 1, the plate-like support wing is made into a small conical cylinder, thereby increasing the strength and suppressing deformation, and further increasing the surface area per piece. However, the front end portion, rear end portion, and left and right end portions of the hook-shaped flap are weak against stress applied from the outside to the inside, and there is room for improvement in strength.

また、特許文献２の気液接触用充填材は、鞍形フラップの前後左右にそれぞれ大円孔が設けられ、この鞍形フラップに大円孔の縁を基部とする円錐筒が上向きと下向きに交互に立設されており、鞍形フラップには円錐筒から放射状に広がる少なくとも３枚の支持翼が立設されている。特許文献２では、複数の支持翼を設けることにより、強度を増大させて変形を抑え、さらに１個当たりの表面積を増大させている。しかしながら、板状の支持翼が放射状に延びていることから、充填材同士が支持翼で干渉し合い、単位体積当たりの充填数が減り、結果として単位体積当たりの表面積が小さくなるという課題がある。   In addition, the gas-liquid contact filler of Patent Document 2 is provided with large circular holes on the front, rear, left, and right sides of the bowl-shaped flap, and the cone-shaped cylinders based on the edges of the large circle holes are directed upward and downward. The wing-shaped flap is provided with at least three support wings extending radially from the conical cylinder. In Patent Document 2, by providing a plurality of support blades, the strength is increased to suppress deformation, and the surface area per one is increased. However, since the plate-like support wings extend radially, the fillers interfere with each other with the support wings, and the number of fillings per unit volume decreases, resulting in a problem that the surface area per unit volume is reduced. .

そこで、本発明の目的は、充填塔に充填した際に自重による変形が少なく、かつ単位体積当たりの表面積を大きくできる気液接触用充填材を提供することにある。   Therefore, an object of the present invention is to provide a gas-liquid contact packing material that is less likely to be deformed by its own weight when packed in a packed tower and that can increase the surface area per unit volume.

上記目的は、下記の如き本発明により達成できる。
即ち、本発明の気液接触用充填材は、４つの大開口部及びこの大開口部よりも小さい４つの小開口部が、周方向に交互に並べて形成された鞍形フラップと、
前記４つの大開口部にそれぞれ連通するように前記鞍形フラップの上下面から突出して形成された円錐筒状の４つの第１突出部と、
前記４つの小開口部にそれぞれ連通するように前記鞍形フラップの上下面から突出して形成された円錐筒状の４つの第２突出部と、を備え、
前記４つの第１突出部は、それぞれ前記鞍形フラップの上下面のいずれか一方の面から突出して形成され、前記周方向に隣接する前記第１突出部同士がそれぞれ前記鞍形フラップから逆方向に突出するように形成されており、
前記４つの第２突出部は、それぞれ前記鞍形フラップの上下面のいずれか一方の面から突出して形成され、前記周方向に隣接する前記第２突出部同士がそれぞれ前記鞍形フラップから逆方向に突出するように形成されており、
前記第１突出部には、中間部から根元部へ向かって延びて前記鞍形フラップに達する第１スリットが外周面に複数本形成されており、
隣り合う２本の前記第１スリットの間の前記第１突出部の外周面と、前記鞍形フラップの上面又は下面とで構成される鋭角な隅部に、側面視にてＶ字状のＶ字リブが形成されていることを特徴とする。 The above object can be achieved by the present invention as described below.
That is, the gas-liquid contact filler of the present invention has four large openings and four small openings smaller than the large openings, which are alternately formed in the circumferential direction,
Four first protrusions in the shape of a conical cylinder protruding from the upper and lower surfaces of the bowl-shaped flap so as to communicate with the four large openings,
Four conical cylinder-shaped second protrusions formed to protrude from the upper and lower surfaces of the bowl-shaped flap so as to communicate with the four small openings, respectively,
The four first protrusions are formed so as to protrude from any one of the upper and lower surfaces of the bowl-shaped flap, and the first protrusions adjacent to each other in the circumferential direction are opposite to each other from the bowl-shaped flap. Formed to protrude
The four second protrusions are formed so as to protrude from either one of the upper and lower surfaces of the bowl-shaped flap, and the second protrusions adjacent to each other in the circumferential direction are opposite to each other from the bowl-shaped flap. Formed to protrude
The first protrusion has a plurality of first slits formed on an outer peripheral surface extending from an intermediate portion toward a root portion and reaching the bowl-shaped flap,
A V-shaped V-shaped side view in an acute corner formed by the outer peripheral surface of the first projecting portion between the two adjacent first slits and the upper or lower surface of the bowl-shaped flap. Characteristic ribs are formed.

第１突出部の外周面と鞍形フラップの上面又は下面とで構成される鋭角な隅部では、外側から内側への応力により鞍形フラップが変形しやすいが、本発明の気液接触用充填材によれば、鋭角な隅部にＶ字リブを形成しているために変形しにくい。また、Ｖ字リブを側面視でＶ字状とすることで、他の充填材の一部がＶ字の切欠き部に進入できるため、充填材同士の干渉が少なく、充填材の充填個数を多くすることができる。その結果、本発明の気液接触用充填材によれば、充填塔に充填した際に自重による変形が少なく、かつ単位体積当たりの表面積を大きくできる。   In the acute corner portion constituted by the outer peripheral surface of the first protrusion and the upper surface or the lower surface of the hook-shaped flap, the hook-shaped flap is easily deformed by the stress from the outside to the inside. According to the material, since the V-shaped rib is formed at the acute corner, it is difficult to be deformed. Further, by making the V-shaped rib V-shaped in a side view, part of other fillers can enter the V-shaped notch, so there is less interference between fillers, and the number of fillers filled can be reduced. Can do a lot. As a result, according to the gas-liquid contact packing material of the present invention, deformation due to its own weight is small when the packed tower is packed, and the surface area per unit volume can be increased.

本発明に係る気液接触用充填材において、前記周方向に隣接する２つの前記第１突出部にそれぞれ形成された前記第１スリットの間に位置する前記鞍形フラップの上下面には、前記大開口部の周縁部に沿って延びる周縁リブが、前記第１突出部の突出方向に突出してそれぞれ形成されていることが好ましい。   In the gas-liquid contact filler according to the present invention, the upper and lower surfaces of the bowl-shaped flaps positioned between the first slits respectively formed in the two first protrusions adjacent in the circumferential direction, It is preferable that peripheral ribs extending along the peripheral edge of the large opening are formed so as to protrude in the protrusion direction of the first protrusion.

周方向に隣接する２つの第１突出部にそれぞれ形成された第１スリットの間に位置する鞍形フラップは、外側から内側への応力により座屈等を起こして変形しやすいが、鞍形フラップの上下面に大開口部の周縁部に沿って延びる周縁リブを形成することで、変形を抑制できる。   The saddle-shaped flaps positioned between the first slits formed in the two first protrusions adjacent to each other in the circumferential direction are easily deformed by buckling or the like due to stress from the outside to the inside. By forming peripheral ribs extending along the peripheral edge of the large opening on the upper and lower surfaces, deformation can be suppressed.

本発明に係る気液接触用充填材において、前記第１突出部の突出方向に沿ったＶ字リブの高さは、前記第１スリットの高さ以下であることが好ましい。   In the gas-liquid contact filler according to the present invention, it is preferable that the height of the V-shaped rib along the protruding direction of the first protruding portion is equal to or less than the height of the first slit.

Ｖ字リブの高さを第１スリットの高さ以下とすることで、鞍形フラップの変形を抑制しつつ、充填材同士の干渉を少なくできる。   By setting the height of the V-shaped rib to be equal to or less than the height of the first slit, it is possible to reduce interference between the fillers while suppressing deformation of the bowl-shaped flap.

図５は、本発明の気液接触用充填材（以下、単に充填材と呼ぶ。）が充填される充填塔１００の一例を示す概略側面図である。この充填塔１００は、有害ガスを液体に吸収させて処理するために使用されるスクラバー装置である。多数の充填材Ｆが充填塔１００の中に充填されており、上方から吸収液を噴霧することで充填材Ｆの表面が濡らされる。表面が吸収液で濡らされた充填材Ｆの下方から有害ガスを含むガスを供給することで、ガスが充填材Ｆ表面の吸収液に接触して有害ガスが吸収される。そして、有害ガスが処理されたガスは上方より排出される。ガスと充填材Ｆの接触面積を大きくして効率良く有害ガスを処理するためには、充填材Ｆの単位体積当たりの表面積をできる限り大きくすることが好ましい。   FIG. 5 is a schematic side view showing an example of a packed tower 100 filled with the gas-liquid contact packing material of the present invention (hereinafter simply referred to as a packing material). The packed tower 100 is a scrubber device that is used for absorbing and processing harmful gases in a liquid. A large number of packing materials F are packed in the packing tower 100, and the surface of the packing materials F is wetted by spraying the absorbing liquid from above. By supplying a gas containing a harmful gas from below the filler F whose surface is wetted with the absorbing liquid, the gas contacts the absorbing liquid on the surface of the filler F and the harmful gas is absorbed. And the gas by which harmful gas was processed is discharged | emitted from upper direction. In order to increase the contact area between the gas and the filler F and efficiently treat the harmful gas, it is preferable to increase the surface area per unit volume of the filler F as much as possible.

また、コークス炉ガス（ＣＯＧ）を処理するための充填塔１００は、巨大なものが多く、内部に充填される充填材Ｆの数が特に多くなる場合がある。そのため、充填塔１００の内部において、下部の充填材Ｆは、上部の充填材Ｆの重量と液体の一時的な重量の負荷が大きく、変形が起こりやすい。充填材Ｆの変形は、有害ガスの処理効率の低下に繋がるため、充填材Ｆの強度を高くすることが望まれる。   Moreover, the packed tower 100 for processing coke oven gas (COG) is often enormous, and the number of fillers F filled therein may be particularly large. Therefore, in the packed tower 100, the lower packing material F is heavily loaded with the weight of the upper packing material F and the temporary weight of the liquid, and is easily deformed. Since deformation of the filler F leads to a reduction in the processing efficiency of harmful gas, it is desired to increase the strength of the filler F.

鞍形フラップ１の上方に向かって湾曲する両端部１ａ，１ｂ、および下方に向かって湾曲する両端部１ｃ，１ｄでは、外側から内側にかかる応力に弱く変形しやすいが、本発明では、Ｖ字リブ２２，２３，２４，２５を設けることにより、鞍形フラップ１の端部１ａ，１ｂ，１ｃ，１ｄでの変形を抑制できる。また、Ｖ字リブ２２，２３，２４，２５を側面視でＶ字状とすることで、他の充填材の一部がＶ字の切込み部に進入できるため、充填材同士の干渉を少なくでき、充填材の充填個数を大きく減らすことはない。   Both ends 1a and 1b that curve upward of the saddle-shaped flap 1 and both ends 1c and 1d that curve downward are susceptible to stress applied from the outside to the inside. By providing the ribs 22, 23, 24, 25, deformation at the ends 1a, 1b, 1c, 1d of the bowl-shaped flap 1 can be suppressed. In addition, by making the V-shaped ribs 22, 23, 24, and 25 V-shaped in a side view, part of other fillers can enter the V-shaped cut portion, so that interference between the fillers can be reduced. There is no significant reduction in the number of fillers filled.
