この発明は防食ライニングに係り、特に排煙脱
硫装置に対して効果的なライニングに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an anti-corrosion lining, and particularly to a lining that is effective for flue gas desulfurization equipment.

ス流入部を中心として防食ライニングを施す。 For example, in a flue gas desulfurization equipment, since exhaust gas containing various corrosive components such as SO 2 flows in, an anticorrosive lining is applied mainly to the exhaust gas inflow part in order to improve the corrosion resistance of the desulfurization equipment itself.

ンガライニングが施される。 Figure 1 shows the system of a flue gas desulfurization equipment that absorbs and removes SO 2 from flue gas by circulating limestone slurry. The exhaust gas first enters the cooling tower 2 from the boiler 1 via the duct 6, and is cooled by the slurry liquid circulated from the cooling tower circulation tank 3.
It enters the absorption tower 4 after SO 2 is removed. Here, the gas-liquid contacts with the slurry liquid circulated from the absorption tower circulation tank 5 to remove SO 2 and is discharged from the chimney 8 via the duct 7. On the other hand, the circulating liquid is added with limestone (CaCO 3 ) in the absorption tower circulation tank 5 and circulated through the absorption tower 4. A part of the circulating liquid is sent to the cooling tower circulation tank 3 through the connecting pipe 9, and is transferred between the cooling tower and these tanks 3 and 5. circulate between. In this method, the dust (soot) from the boiler 1 is absorbed into the slurry as it is and mixed with the generated gypsum (CaSO 4 , 2H 2 O) (soot mixing method). In the case of this soot mixing method, limestone (CaCO 3 ), sulfite gypsum (CaSO 3 , 1/2H 2 O) and gypsum (CaSO 4 , 2H 2 O) are contained in the slurry in any part of the desulfurization system. Therefore, the corrosion state within the desulfurization system is almost the same in all parts.
The desulfurization system only needs to be provided with one anti-corrosion lining. In other words, a resin lining made of a mixture of resin and glass flakes (referred to as "flake lining") has been used for the entire interior of the desulfurization equipment, and since the linings are of the same type, no special lining joints are required. Note that a wear-resistant brick lining is applied to the cooling tower throat portion 10 where local wear occurs.

ない。 In contrast to the soot mixing method described above, a soot separation method in which dust is removed from the exhaust gas supplied to the desulfurization equipment in advance, from the viewpoint of changing the fuel used in the combustion equipment that is the source of exhaust gas generation, and improving the quality of gypsum generated during deflow. are increasingly being adopted.
In particular, when a combustion device switches from petroleum-based fuel to coal-based fuel, the amount of dust (soot) in the exhaust gas increases significantly, so a soot separation method is required.

０の施工が問題となる。 To explain the outline of the desulfurization method using this soot separation method with reference to FIG. 2, the exhaust gas discharged from the boiler 1 heats the treated gas discharged from the absorption tower 4 in the heat exchanger 11, and the self is cooled. Reduces negative loads in cooling towers. The exhaust gas flowing into the cooling tower 2' is cooled by cooling water supplied from the circulation tank 3', and the ducts in the exhaust gas are removed. In this case, in the soot separation system, the purpose of the cooling tower 2' is to remove tost from the exhaust gas rather than to cool the exhaust gas. The exhaust gas cooled and dust-removed in the cooling tower 2' absorbs and removes SO 2 in the absorption tower 4, and then passes through the duct 7,
It passes through the eliminator 12 and is discharged from the chimney 8.
In this type of desulfurization apparatus, the circulating water supplied from the circulation tank 3' is fresh water, but during circulation it absorbs a small amount of SO 2 in the exhaust gas and becomes dilute sulfuric acid with a pH of 1 to 2. In addition, since chlorides and fluorides are absorbed and concentrated, the flake lining used in the soot mixing method described above cannot be used. That is, since glass, which is the main component of this flake lining, is attacked by fluorides, rubber, which is not attacked by fluorides, is used as the lining. However, the exhaust gas from which fluorides have been removed in the cooling tower 2 flows into the absorption tower 4 following the cooling tower 2. For this reason, the interior of the absorption tower 4 can be provided with a conventional flake lining. Therefore, in the soot separation method, different linings are provided in one desulfurization system, and the cooling tower 2', which is the contact area (joint area) of these different linings, is connected to the connection area of the absorption tower 4, that is, the throat area. 1

脱落が問題となる。 FIG. 3 shows the state of the conventional lining of the throat section. The throat part is lined with bricks with increased wear resistance, and 13 is a soft rubber placed on the side of the base material 14, 13 is a hard rubber, 16 is a brick joint material, and 15 is a brick. In order to increase the adhesive force between the bricks 15 and the rubber, the rubber is made of two layers, one soft and one hard, and the hard rubber 13 is placed on the brick 15 side. Epoxy resin is used as the adhesive 17, but if only this adhesive is used, there is a risk that the bricks 15 will fall off due to deterioration in the efficiency of the resin. For this purpose, as shown in FIG. 4, a hook 18 is formed on the base material 14,
A method of locking the brick 15 to the hook 18 has also been implemented, but since the hook locking groove 15a is formed in the brick, the strength of the brick is inevitably insufficient, and the brick may be damaged due to cracks in the brick. Falling off becomes a problem.

It is an arm formed against. Throat part 10
The lowest brick among the bricks formed is not only locked by this hook but also placed on the arm 20 to prevent the brick from falling off. Note that this hook portion can be provided in multiple stages. 13' is a soft rubber lining attached to the base material 14 side, and 13 is a hard rubber lining attached to this soft rubber lining 13'. The bricks 15 are secured to these rubber-lined hooks and are bonded with an adhesive 17. This lowest brick 15 is placed on the arm 20 to prevent the brick from falling off. A lining 19 is attached to the arm 20 and is made of butyl rubber or carbon flake, which has high resistance to fluorides. Also, an effective adhesive is an epoxy resin with A10 added.
