本発明は、湿式排煙脱硫装置の吸収塔に係り、特にドラ
フト損失が小さく、脱硫効率が高い湿式排煙脱硫装置の
吸収塔に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an absorption tower for a wet flue gas desulfurization equipment, and particularly relates to an absorption tower for a wet flue gas desulfurization equipment that has low draft loss and high desulfurization efficiency. be.
湿式排煙脱硫装置において、硫黄酸化物含有ガスと吸収

ある）はドラフト損失が小さく、構造が簡単であるとい
う利点を有している。しかし、その反面スプレー塔内を
流れるガス流速が不均一になり易く偏流が発生するため
に、高い脱硫率が得られにくいという問題がある。In wet flue gas desulfurization equipment, a known absorption tower that brings the sulfur oxide-containing gas into gas-liquid contact with the absorbent slurry is equipped with a spray nozzle that sprays the absorbent slurry. A tower (hereinafter also referred to as a spray tower) has the advantages of low draft loss and simple structure. However, on the other hand, there is a problem in that it is difficult to obtain a high desulfurization rate because the gas flow rate inside the spray tower tends to be non-uniform and uneven flow occurs.
この問題を解決するために種々の工夫がなされており、
その代表的なものとしてスプレー塔下部の被処理ガスの

A typical example is one in which a perforated plate is provided at the inlet of the gas to be treated at the bottom of the spray tower (Japanese Patent Laid-Open No. 54-16158
No. 7), a perforated plate in the introduction part of the gas to be treated and a cleaning spray for cleaning the lower surface of the perforated plate (Japanese Patent Application No. 6)
No. 0-140625), and one in which a perforated plate is provided in the gas introduction section and an absorption liquid inflow prevention plate is known to prevent the absorption liquid slurry from scattering into the gas introduction pipe to be treated are known.

浄スプレーｌＯを有するとともに、ガス入口ダクト５と
スプレー塔本体１との連結部に吸収液流入防止板１ｌが
設けられている。FIG. 5 is an explanatory diagram showing such a spray tower. This spray tower has a perforated plate 9 and a cleaning spray lO at the gas inlet to be treated, and an absorbent inflow prevention plate 1l is provided at the connection between the gas inlet duct 5 and the spray tower main body 1.

へ排出される。The exhaust gas containing sulfur oxides introduced into the spray tower main body 1 from the gas inlet duct 5 passes through the perforated plate 9 and rises to the spray nozzle 2 provided at the upper part of the spray tower main body 1.
After the sulfur oxides are removed by contact with the absorption liquid slurry sprayed from the gas, it is discharged from the system through the gas outlet duct 7 as a process gas.

収液スラリをスプレーすることによりスケールの発生を
防止し、また吸収液流入防止板１１は、多孔＃ｉ９を通
過して下降する吸収液スラリかガス入口ダクト５内に飛
散することを防止している。At this time, the cleaning spray 10 sprays the absorption liquid slurry onto the lower surface of the porous plate 9 to prevent scale formation, and the absorption liquid inflow prevention plate 11 prevents the absorption liquid slurry from flowing down through the holes #i9. This prevents the gas from scattering into the gas inlet duct 5.
しかしながら、上記従来技術には、多孔板によるドラフ

強くなる。また、多孔板の下面へのスケーリングを防止
するために、洗浄用スプレーから多量のスラリーを噴出
させねばならず、循環ポンプが大型化し、消費電力量が
増大するという問題がある。However, the above-mentioned conventional technology has the drawback that the draft loss due to the perforated plate is large. For example, when the concentration of sulfur oxides in the exhaust gas is high or when a high desulfurization rate is required, the amount of circulating absorption is increased. This trend will become even stronger. Furthermore, in order to prevent scaling to the lower surface of the perforated plate, a large amount of slurry must be ejected from the cleaning spray, which increases the size of the circulation pump and increases power consumption.
本発明の目的は、上記従来技術の問題点を解消し、ドラ
フト損失が小さく、優れた脱硫性能が得られるとともに
、消費電力量が少ない湿式排煙脱硫装置の吸収塔を提供
することにある。An object of the present invention is to provide an absorption tower for a wet flue gas desulfurization apparatus that eliminates the problems of the prior art described above, has low draft loss, provides excellent desulfurization performance, and consumes little power.

同じかそれ以下である格子板からなる気液分散器を設け
たことを特徴とするものである。In order to achieve the above object, the present invention provides a wet flue gas desulfurization device that absorbs sulfur oxides in the flue gas by bringing the flue gas introduced into the lower part of the tower into contact with the absorption liquid sprayed from the spray nozzle in the upper part of the tower. In the absorption tower, a gas-liquid disperser is provided at the introduction part of the exhaust gas, the gas-liquid disperser consisting of a lattice plate having a lattice height of 50 nm or more and a lattice width the same as or less than the height of the lattice. It is something to do.

た、格子板は多孔板と比較して開口面積が大きくとれる
ので、ドラフト損失が低減される。By installing a gas-liquid disperser consisting of a grid plate with a grid height of 50@■ or more and a grid width equal to or less than the height of the grid at the introduction part of the gas to be treated at the bottom of the spray tower. , since the entire surface of the gas-liquid disperser becomes a completely wetted wall,
The generation of scale can be suppressed without cleaning the lower surface of the gas-liquid distribution plate, and the gas-liquid contact efficiency is improved. Further, since the grid plate has a larger opening area than the perforated plate, draft loss is reduced.

堆積する原因となる。In the present invention, the height of the grid forming the grid plate is set to 50
mm or more, and the pitch of the grating is the same as or narrower than the height of the grating. When the height of the grid is less than 50 m, the overall wetted wall area becomes narrow, the gas-liquid contact efficiency decreases, and the gas flow flowing inside the column cannot be rectified sufficiently. Furthermore, if the width of the grid plate is wider than the height of the grid, the rectifying effect of the gas flow will be reduced, and the absorbed liquid slurry that passes through the gas-liquid distributor and descends will be easily scattered, for example in the gas inlet duct. This may cause slurry to build up.

It is possible to prevent the accumulation of

Mainly consists of a gas-liquid disperser 12, a circulation tank 8 for absorption liquid slurry provided at the lower part of the spray tower main body 1, and a circulation bomb 6 for circulating the absorption liquid slurry in the circulation tank 8 via the spray pipe 3. It is being organized.

７から系外に排出される。The sulfur oxide-containing exhaust gas is introduced into the spray tower main body 1 from the gas inlet duct 5, contacts the absorption liquid on the surface of the gas-liquid disperser 12, which is a wetted wall with the absorption liquid slurry, and is partially desulfurized. , the flow rate is made uniform by passing through the gas-liquid disperser 12, and then comes into contact with the absorption liquid slurry sprayed in a conical shape through the spray pipe 3 and the spray nozzle 2, where most of the sulfur oxides are removed. After the entrained mist is removed by a mist catcher 4 provided at the upper part of the spray tower main body 1, it is discharged out of the system from a gas outlet duct 7 as a processing gas.

In addition, the wetted wall improves the gas-liquid contact efficiency.
This improves the desulfurization rate. Furthermore, scattering of the absorption liquid slurry descending through the gas-liquid distributor 12 is prevented, so that, for example, there is no accumulation of slurry in the gas inlet duct.

When sulfur oxides in the sulfur oxide-containing exhaust gas were absorbed using a grid pitch of 5011, limestone slurry as the absorption liquid, and an exhaust gas amount of 2500 mN/h (gas space at the absorption tower inlet), the deflow rate was 95%. The draft loss at this time was 5 mmH20. In addition, no scale was observed to adhere to the lattice-shaped gas-liquid disperser 12, and no slurry was observed to accumulate in the gas inlet duct 5.

It can be seen that (Comparative Example 2) can prevent scaling to the gas-liquid disperser 12, but the desulfurization rate decreases.

Since the gas-liquid contact efficiency improves, the desulfurization efficiency improves. In addition, draft loss is reduced and a sufficient rectification effect can be obtained. Furthermore, since the absorption liquid slurry sprayed conically from the spray nozzle is prevented from scattering, it is possible to prevent the slurry from accumulating in the gas inlet duct, for example.
