摘要： PROBLEM TO BE SOLVED: To provide a fly ash collector being dependent on a comparatively miniature moving bed, in which corrosive exhaust gas, soot and dust contained in high-temperature corrosive exhaust gas included in combustion exhaust gas can be removed without extremely lowering the temperature of combustion exhaust gas. SOLUTION: In the fly ash collector for collecting fly ashes contained in incineration exhaust gas, the inside of a dust collection chamber is comparted into at least two dust collection chambers 131, 132. Filter media (a) having large particle sizes are used in the dust collection chamber on the upstream side of exhaust gas and filter media (b) having small particle sizes are used in the dust collection chamber on the downstream side of exhaust gas and thereby fly ashes are collected.

摘要： PURPOSE:To effectively treat exhaust gas contg. a lot of dust without wasting an expensive carbon material by installing a layer of a dust collecting material on the exhaust inlet side of a reactor and next installing a layer of a carbon material for desulfurization and denitration. CONSTITUTION:A simple partition means 3 is installed inside a reactor 1 and the 1st and 2nd moving beds 4, 5 are formed in this order from the exhaust gas inlet side. A dust collecting material 6 is fed to the 1st layer 4 and a carbon material 7 is fed to the 2nd layer forming a main reaction layer to make them flow from above to under. The exhaust gas is passed through a louver structure 2 on the exhaust gas inlet side to feed it to the reactor 1. After the exhaust gas is first deprived of most of dust in the 1st layer 4, it enters the 2nd layer 5 where harmful materials such as sulfur oxide and nitrogen oxide are adsorbed, decomposed and removed. After that, the fallen dust collecting material 6 and carbon material 7 join with each other to be transferred to a separator 11 where collected dust and pulverized matter are separated and further the dust collecting material 6 and carbon material 7 are separated. And, the dust collecting material 6 is circulated and reused as it is and the carbon material 7 is circulated and reused after regeneration.

摘要： PURPOSE:To continuously and efficiently treat exhaust gas containing dust, nitrogen oxides, and sulfur oxides such as exhaust gas of Diesel engine, exhaust gas of boiler, etc. CONSTITUTION:An exhaust gas treating zone 26 is provided on the upper section of a moving bed of particles and a regeneration zone 32 is provided in the lower section of the bed to incinerate collected dust. The particles containing ash discharged from the lower section of the bed are sepatated into ash and regenerated particles in an ash separating device 36, while the regenerated particles are circulated to the upper section of the bed for reuse. And, the moving bed may be divided into three sections, i.e. upper section as exhaust gas treating zone 26, middle section as regeneration zone 32, and lower section as preheat zone 44. Further, part or whole of the particles can be formed into particles having desulfurization activity or particles having denitration activity or particles having desulfurization activity and particles having denitration activity or particles having simultaneous desulfurization and denitration activity, so that SOx or NOx can be removed simultaneously with dust, or SOx and NOx can be removed simultaneously with dust.

摘要： PURPOSE: To use granular bed filters with which easy removal, maintenance and repacking are assured and to make it possible to execute purification of gas under a positive pressure by stacking these granular bed filters in a pressure vessel. CONSTITUTION: Each of filter shells 2 having inlet ports 7 and outlet ports 13 for bulk material comprises the plural granular bed filters 8 arriving at a raw gas inlet duct 5 and a refined gas outlet port 6 connected to a common outlet duct 6a. The granular bed filters 8 are stacked in the pressure vessel 2. Namely, the designing of the apparatus for executing the purification of the gas under the positive pressure is made possible by using the granular bed filter with which the easy removal, maintenance and repacking are assured.
