【考案の詳細な説明】
本考案の目的は、水分の浸透性が極めて低く、
水洗処理が容易で、かつ耐衝撃性の大なる移動層
式ガス吸収装置用ボールを提供することである。[Detailed explanation of the invention] The purpose of this invention is to have extremely low moisture permeability.
To provide a ball for a moving bed type gas absorption device that is easy to wash with water and has high impact resistance.

When a ball is used as a carrier for a gas absorbent and a heat medium, and the layer is repeatedly wet and dry, the water that permeates inside the ceramic ball in the wet state evaporates in the high-temperature dry state, causing the ball to dry. It has been found that this increases the internal pressure of the ball, causing the ball to explode.

するためである。 Furthermore, when the gas absorption device is stopped, it is necessary to prevent products of the gas absorption reaction, such as calcium chloride, from adhering to the ball surface. This is to prevent the adhesion of such hygroscopic salts from promoting water penetration into the interior of the ball.

摩耗が促進される。 Ceramic balls have superior mechanical properties compared to balls made of other materials, but as mentioned above, water penetrating inside generates high vapor pressure at high temperatures, causing the balls to explode. Another disadvantage is that the surface is relatively rough, which makes it easy for reaction products to adhere to it, which in turn tends to cause balls to adhere to each other. Furthermore, the wear of the ball is accelerated due to an increase in the coefficient of friction on the ball surface due to deposits on the ball surface.

つた。 In order to prevent the ball from exploding, it is necessary to prevent moisture from entering the ball. Therefore, we attempted to create an extremely thin synthetic heat-resistant polymer coating on the surface of a ceramic ball, and conducted tests using a prototype.
その結果、ボール表面の被覆材として、種々の
フツ素樹脂が適していることが判明した。 As a result, it was found that various fluororesins were suitable as coating materials for the ball surface.

た。 In particular, tetrafluoroethylene resin (PTFE) showed remarkable effects. In this case, in addition to the main effect of controlling moisture penetration, the effect of improving the ability of dust to escape from the ball surface was observed. It has been proven that it can withstand extremely long-term use in the reaction layer of actual equipment.

It has been found that performing a scorching heat treatment as a pretreatment has a remarkable effect on preventing the ball from exploding.
The conditions for the scorching treatment are 350°C for 2 hours, and the suitable coating method is to immerse the ball in a sticky molten synthetic resin liquid. After soaking, the dried balls are used as a carrier of gas absorbent for the reaction layer and as a heat transfer medium.

る。 The heat resistance of coated balls of usable thickness is all above 350°C, and their absorbency is reduced to less than 30% of the value of uncoated ceramic balls. Balls coated with polytetrafluoroethylene resin (PTFE) have a service life of more than 10,000 hours in a moving bed gas absorption device.

３ ボール表面の摩擦係数の低下により、耐久性
が著しく向上した。3.Durability has been significantly improved due to a reduction in the coefficient of friction on the ball surface.
４ ガス吸収装置停止時の水洗が容易になつた。4. It has become easier to wash the gas absorption equipment with water when it is stopped.
