Description
Technical Field
The present invention relates to a moving bed particulate filter.
Background
The production mode of the smelting furnace such as the converter is intermittent, namely, the smelting furnace is emptied, reloaded and other preparation activities are carried out before and after smelting production.
During the preparation activity, no intensity smelting exists, the smoke gas component is mainly air, the smoke gas temperature is slightly increased after the air is heated and radiated, and no intensity smoke dust exists.
During smelting production, along with the improvement of smelting intensity, the temperature of the flue gas escaping from the furnace mouth can reach 1600 ℃, the content of CO in the flue gas component can reach 90%, and the dust carried by the flue gas can reach 150g/Nm 3 The dust has complex components mainly including FeO and Fe 2 O 3 CaO, etc., the evolved fumes and fumes will also undergo exothermic oxidation reactions etc. in the subsequent flue.
The smelting production time is generally not longer than twenty minutes, and the preparation activity time is generally not longer than twenty minutes. Because of the rapid intermittent production mode, converter flue gas treatment facilities, especially high-temperature facilities, need to have strong capability of coping with cold and hot impact in a large temperature area, dust impact with large concentration and explosive gas accumulation.
In the prior art at home and abroad, the production mode with highest energy recycling efficiency is as follows: the sealed vaporization cooling flue is arranged, the sensible heat of the flue gas above 800 ℃ is transferred into water vapor by taking the radiant heat form as the main, the spray or evaporation type direct cooling tower is arranged to reduce the temperature of the flue gas to below 70 ℃ or 250 ℃, and the flue gas with high CO content and O is recovered and utilized 2 Low content converter gas. Sensible heat of flue gas below 800 ℃ cannot be recovered due to the fact that the components of the flue gas are explosive, the content of smoke dust is high, and the like.
The spray type direct cooling tower reduces the temperature of the flue gas to below 70 ℃, and most of smoke dust can be cleaned while the flue gas is cooled, but the problems are that: sensible heat is not recovered, water consumption is high, and sewage needs to be treated. The evaporation type direct cooling tower reduces the temperature of the flue gas to below 250 ℃, and part of large-particle smoke dust can be separated while cooling the flue gas, but the problems are that: sensible heat is not recovered and steam consumption is high. In order to meet the requirement of flue gas sensible heat recovery below 800 ℃, the converter flue gas needs to be subjected to high-temperature dust removal.

Ceramic filters, too cotton hard surface filters and the like can also meet the requirements of high-temperature dust removal, but have the problems of fragility, water resistance and the like, and are not very expensive.
Cyclone dust collectors (including multi-tube dust collectors) are relatively mature high-temperature dust collection technologies and are widely applied to industrial fields such as fluidized bed boilers, but are difficult to collect particles with particle diameters of less than 5 μm and cannot be used for atmospheric emission control.
The particle layer filter (including a rake particle layer filter, a cyclone particle layer filter, a moving bed particle layer filter and the like) has the advantages of high temperature resistance, impact resistance, wide sources of filter materials and the like, but has no research experience for intermittent production, has no research experience for explosive gas, is difficult to capture tiny particles, and cannot be used for atmospheric emission control.
