Abstract
【課題】垂直な塔内に固体粒子や充填物を充填し、気液の接触を目的として運転される化学装置（例えば硫酸製造設備における、冷却洗浄塔、転化器、乾燥塔、吸収塔等）において、固体粒子や充填物を保持する格子状構造体としてのポリプロピレン製ユニット式グリッドバーが長期運転中に移動や変形を防止するポリプロピレン製固定冶具を提供する。【解決手段】気液の接触を目的として運転される化学装置に用いられるポリプロピレン製板状矩形固定治具Ａ、Ｂであって、塔内に充填する固体粒子や充填物を保持するポリプロピレン製格子状構造体であるユニット式グリッドトレーの隣り合うユニット式グリッドトレーの連結固定棒（丸棒）２端部どうしを跨ぐＵ字型切り欠き溝を有し、切り欠き溝は、隣り合うユニット間隙の厚みと下部トレー支持台（アーチ）幅の長さ及びグリッドバーの高さの形状を有する。【選択図】図１A chemical apparatus in which solid particles and packing are packed in a vertical tower and operated for the purpose of gas-liquid contact (for example, a cooling washing tower, a converter, a drying tower, an absorption tower, etc. in a sulfuric acid production facility) The polypropylene unit-type grid bar as a grid-like structure for holding solid particles and packing is provided with a polypropylene fixing jig that prevents movement and deformation during long-term operation. SOLUTION: Polypropylene plate-like rectangular fixtures A and B used in a chemical apparatus operated for gas-liquid contact, and a polypropylene grid for holding solid particles and packing packed in a tower Unit-type grid tray, which is a unit structure, has a U-shaped notch groove straddling the two ends of the connecting grid (round bar) of adjacent unit-type grid trays.

Description
化学装置（例えば硫酸製造設備における、冷却洗浄塔、転化器、乾燥塔、吸収塔等）においてポリプロピレン製品の溶接部の耐食性や強度的劣化が問題になる場合がある。
溶接部を一切排したポリプロピレン製ユニット式グリッドトレーはポリプロピレン製グリッドバーを固定棒、スペーサーで連結、端部をストッパーで固定しユニット構成され当該課題を解決する手段として有効である。しかし運転中にグリッドトレーには梁強度計算モデルでは解析できない気液流動体や充填物の複雑な振動、偏心荷重が作用する。その場合、固定棒端部でトレーバーを固定するストッパーが損傷してグリッドバー及びユニット全体が移動や変形を起こす恐れがある。長期間の運転中にストッパーが損傷しても移動や変形に依って空隙率（グリッドバー間隔）が変化しないような安全対策が必要である。In a chemical apparatus (for example, a cooling washing tower, a converter, a drying tower, an absorption tower, etc. in a sulfuric acid production facility), corrosion resistance and strength deterioration of a welded part of a polypropylene product may be a problem.
The unit grid tray made of polypropylene without any welds is composed of a unit made by connecting a polypropylene grid bar with a fixing rod and a spacer and fixing an end with a stopper, and is effective as a means for solving the problem. However, during operation, complex vibrations and eccentric loads of gas-liquid fluids and packings that cannot be analyzed by the beam strength calculation model are applied to the grid tray. In this case, the stopper that fixes the tray bar at the end of the fixing bar may be damaged, and the grid bar and the entire unit may move or be deformed. Safety measures are necessary so that the porosity (grid bar interval) does not change due to movement or deformation even if the stopper is damaged during long-term operation.
上記化学装置に使用される耐酸磁器製グリッドトレーはポリプロピレン製グリッドトレー（トレーバー、連結固定棒、スペーサー、端部ストッパーで構成）のように工場でユニット化してから現場据え付けすることは困難であるため現場でグリッドバー間隙にグリッドブロックを装入してトレー空隙率とトレー位置固定を図る。
一方工場で加工されユニット化されたポリロピレン製グリッドトレーは据付け現場の塔内でトレー支持台上に平面的敷設後、そのまま充填物を装入して運転に入る。
運転中に気液流動体、充填物の振動や充填物偏心荷重に依って固定棒の端部ストッパーが損傷してグリッドバー単体或はユニット一式が移動・変形する恐れがある。従って気液流動体や充填物に起因する複雑な振動や偏心荷重を最小限に抑えるため個々のユニットグリッドトレーを据付け後、トレーバー間隔を一定に保持すると同時に隣り合うユニットの固定棒端を跨ぐ板状固定冶具が必要である。The acid-resistant porcelain grid trays used in the above chemical equipment are difficult to install in the field after being unitized at the factory, such as polypropylene grid trays (consisting of tray bars, connecting and fixing bars, spacers, and end stoppers). At the site, a grid block is inserted into the gap between the grid bars to fix the tray porosity and the tray position.
On the other hand, the polypropylene grid tray processed and unitized in the factory is laid flat on the tray support in the tower of the installation site, and then the packing is loaded as it is to start operation.
During operation, the end stopper of the fixed bar may be damaged due to the gas-liquid fluid, the vibration of the packing, or the eccentric load of the packing, and the grid bar alone or the unit set may move or deform. Therefore, in order to minimize the complicated vibration and eccentric load caused by gas-liquid fluid and packing, after installing individual unit grid trays, a plate that keeps the tray bar spacing constant and at the same time straddles the end of the fixed bar of the adjacent unit A shape fixture is required.

本考案は硫酸製造設備など垂直な塔内に固体粒子や充填物を充填し、気液の接触を目的に運転される化学装置において、固体粒子や充填物を保持するグリッドトレー（図１）が振動や偏心荷重を受けても空隙率変化や機械的損傷が無い様、隣り合うグリッドトレー間の間隙を埋めると同時に相互に連結してグリッドトレー全体の機能維持を図るために設置される固定冶具である。[Industrial application fields]
The present invention is a chemical apparatus in which solid particles and packing are packed in a vertical tower such as a sulfuric acid production facility and operated for the purpose of gas-liquid contact. A grid tray (FIG. 1) for holding solid particles and packing is provided. Fixing jigs installed to fill the gaps between adjacent grid trays and maintain the functions of the entire grid tray by filling them together so that there is no change in porosity or mechanical damage even when subjected to vibration or eccentric load It is.
充填物を有する化学装置は、その下部に気体及び液体が通過する空間を持つ複数のアーチ（図４の５）が耐酸磁器煉瓦やＦＲＰライニング構造体によって構築され、このアーチの上にユニット式ポリプロピレン製格子状構造体〔即ちグリッドトレー：（図３及び図４の１）〕が隣り合って個々に整列され塔内全体に整列・平面状に敷設される。 In a chemical apparatus having a filling, a plurality of arches (5 in FIG. 4) having spaces through which gas and liquid pass are constructed by acid-resistant porcelain bricks and FRP lining structures, and unit polypropylene is provided on the arches. Grid-like structures [i.e. grid trays: (1 in FIGS. 3 and 4)] are arranged next to each other and arranged in a flat manner in the entire tower.
一平面内に敷設された個々のグリッドトレーは相互に連結、固定しないと運転中に振動や上記アーチ（図４の５）が傾斜や凹凸のため移動して互いが重なって変形や離反する恐れがある。その結果グリッドトレーの空隙率が変化や極端な場合にはグリッドバーが変形して性能に支障をきたす事がある。 If the individual grid trays laid in one plane are not connected or fixed to each other, vibration or the arch (5 in Fig. 4) may move during operation due to inclination or unevenness and may overlap and deform or separate. There is. As a result, when the porosity of the grid tray is changed or extreme, the grid bar may be deformed to hinder the performance.
本考案は、塔内に充填する固体粒子や充填物を保持する格子状構造体、即ち隣り合う各々のユニット式グリッドバー両端固定ロッド部分（図・・・）を跨ぐ固定支持具で連結することに依りグリッドトレー面全体を緊縛固定する事が可能となり、予めセットした固定棒両端のストッパーが損傷した場合でもグリッドバーの重なり、離反、変形等の防止策の役割をする。 In the present invention, a grid-like structure holding solid particles or packing packed in a tower, that is, connecting each of adjacent unit-type grid bar both-end fixed rod portions (FIG.. Therefore, the entire grid tray surface can be tightly fixed, and even if the stoppers at both ends of the fixed bar set in advance are damaged, it serves as a preventive measure against grid bar overlap, separation, deformation and the like.
本考案のポリプロピレンを材質としたユニット式グリッドトレー間の固定支持具の構造を示す。・・・図Ａ（両端部用）、図Ｂ（中央部用）
ユニット式グリッドトレーの両丸棒端部を跨ぎ連結する。グリッドバーと固定冶具は十分な接触面を有するため隣り合う双方のグリッドバーの面間隔は常に正常に保たれ充填物の一時的偏在が（偏心荷重）あっても有害な傾斜や変形を防ぐことが出来る。The structure of the fixed support between unit type grid trays which made the polypropylene of the present invention a material is shown. ... Figure A (for both ends), Figure B (for center)
Connect across the ends of both round bars of the unit type grid tray. Since the grid bar and the fixture have sufficient contact surfaces, the spacing between the adjacent grid bars is always kept normal to prevent harmful tilting and deformation even if there is a temporary uneven distribution of the filler (eccentric load). I can do it.
隣り合うポリプロピレン製ユニット式グリッドトレーの固定棒端を跨ぐよう切り欠きを有した板状固定冶具を全ての対象箇所に装入した結果、グリッドトレーは互いに強固に結束され固定棒両端ストッパーの損傷及びトレーバー間隔は常に垂直に保つことが可能となり安定操業に貢献した。 As a result of loading plate fixing jigs with notches so as to straddle the ends of the fixed rods of adjacent unit grid trays made of polypropylene, the grid trays were tightly bound together and damaged the stoppers at both ends of the fixed rods. The distance between the tray bars can be kept vertical all the time, contributing to stable operation.
化学装置において、原料の多様化によりフッ酸化合物を含んだ原料が増加している。耐食性能に加え大型塔内工事の安全性に適合したポリプロピレン製ユニット式グリッドトレーの利用価値が増加している。大型塔内では運転中にポリプロピレン製ユニット式グリッドトレーは局所的に複雑な力（振動、熱膨張、滑り移動等）を受ける。ここに提案するポリプロピレン製固定支持具は工場出荷時に設置される固定棒両端ストッパーの安全性を現場施工時に補完する確実且つ簡便なものである。大型化する装置に於いて利用の可能性が高まると考える。 In chemical equipment, raw materials containing hydrofluoric acid compounds are increasing due to diversification of raw materials. In addition to corrosion resistance, the utility value of polypropylene unit grid trays that are suitable for the safety of large-scale tower construction is increasing. During operation in the large tower, the unit grid tray made of polypropylene is locally subjected to complex forces (vibration, thermal expansion, sliding movement, etc.). The polypropylene fixed support proposed here is reliable and simple that complements the safety of the stoppers at both ends of the fixing rod installed at the time of factory shipment at the time of construction on site. I think that the possibility of use increases in the equipment which enlarges.
