The present invention relates to an apparatus for efficiently removing quicklime particles using a moving bed using a mixture of quicklime particles and sand particles having a larger diameter than the quicklime particles.

ような反応式で生石灰と消化反応する。 The present inventors have already developed a moving bed reactor using quicklime particles for the purpose of removing hydrogen chloride and sulfur oxides from waste incinerator exhaust gas.
When waste incinerator exhaust gas, especially municipal waste incinerator exhaust gas, is treated with this equipment, municipal waste incinerator exhaust gas has a high moisture content, and the exhaust gas is usually cooled to 250-300℃ by a waste heat boiler or water injection. However, with waste heat boiler cooling, the moisture content reaches 15-25%, and with water injection cooling, the moisture content reaches 35-45%, and the moisture in the exhaust gas undergoes a digestion reaction with quicklime in the following reaction formula.
CaO＋H2O→Ca（OH）2

ルシウムを生成する。 CaO + H 2 O → Ca (OH) 2 Generally, in this digestive reaction, quicklime is known to be a hydraulic substance that becomes a hardened form of slaked lime that has expandability. However, carbon dioxide in the exhaust gas also reacts with quicklime to produce calcium carbonate according to the following reaction formula.

少なくすれば、硬化現象を減ずることができる。 CaO + CO 2 → CaCO 3 This carbonation reaction suppresses the digestive reaction, so the more carbon dioxide and less water in the exhaust gas, the less hardened lime is produced. Therefore, waste heat boiler cooling gas has a lower rate of producing hardened slaked lime than water injection cooling gas. Incidentally, in experiments conducted by the present inventors, hardened lime slaked lime was not produced with waste heat boiler cooling gas, but hardened lime was sometimes produced with water injection cooling gas depending on the operating conditions. When this hardening phenomenon occurs, the movement of particles becomes poor and the pressure loss in the moving bed increases, causing trouble in the operation of the apparatus. A hardened body of slaked lime is produced due to the direct contact of quicklime particles, and by reducing the frequency of direct contact, the hardening phenomenon can be reduced.
上記の諸点に鑑み、本考案者らは種々の実験を

It is an object of the present invention to provide a dry moving bed reactor for incinerator exhaust gas.
