Description
Technical Field
The utility model belongs to the field of chemical tail gas treatment, and particularly relates to a dangerous waste tail gas treatment reaction bin.
Background
With the rapid development of industry, the more hazardous wastes generated in industrial production bring about great threat to ecological environment and human health, and people pay more attention to the treatment of the hazardous wastes. Most of the solid waste treatment in China at the present stage is incineration by an incinerator, and a dry deacidification system using lime and active carbon as absorbents is arranged in a flue gas treatment system after the incineration of the solid waste. The flue gas after solid waste incineration is subjected to boiler waste heat recovery, quench tower cooling, dry deacidification tower deacidification and dioxin removal and the like, bag dust collector dust removal, alkaline tower sulfur dioxide removal, wet electric dust collector dust removal, induced draft fan pressurization, flue gas heater heating, SCR denitration and finally discharged to a chimney. The flue gas at the outlet of the quenching tower enters a dry deacidification tower, slaked lime is added into the flue gas through a lime device to carry out preliminary dry deacidification, and activated carbon is added into the flue gas through an activated carbon device to adsorb part of dioxin and other harmful substances in the flue gas.
The flue gas at the outlet of the dry deacidification tower carries active carbon and slaked lime to enter the bag-type dust collector, and the active carbon and the slaked lime are attached to the bag together with the trapped smoke dust when the flue gas passes through the filter bag, so that the deacidification and adsorption efficiency can be continuously ensured by contacting with the flue gas. The dry deacidification system consists of a dry deacidification tower, a lime bin, an activated carbon bin, a lime blowing device, an activated carbon blowing device and a lime activated carbon feeding winch.
At present, lime and activated carbon are fed manually, bagged lime and bagged activated carbon are conveyed to the tops of two bins by a winch, and the packaging bags are manually cut off and respectively added to inlets at the tops of the lime bin and the activated carbon bin. Because lime bin and active carbon storehouse are not the negative pressure at this moment, lead to the charge door to have lime dust or active carbon dust to come out, the workman need wear goggles, gauze mask, has very strong occupational health hidden danger. Lime active carbon consumption is low, and the material is injected once in 2-3 days generally. The working time is about 0.5h each time. In order to save construction cost, running cost and other reasons, an induced draft dust removing device is not added to the active carbon bin of the lime bin generally.
Summarizing the above, the inventor believes that the conventional method of adding lime and activated carbon causes irreversible damage to the body of an operator and causes waste of lime and activated carbon, so that there is a need for an exhaust gas treatment device that can avoid overflow of lime and activated carbon and reduce waste of dust and raw materials.
