Problems solved by technology
After testing, it is found that about 50% of the powder is discharged when the incineration method is used to treat dust such as purified ash while obtaining energy, which will cause secondary pollution; in addition, due to the low calorific value of the powder, it is not easy to ignite

The invention discloses a comprehensive recycling method and a comprehensive recycling system for ash resources of a calcium carbide factory. The method comprises the following steps: classifying andcollecting various ash resources generated in the production process of a calcium carbide furnace into different ash storage tanks; mixing two or more ash resources into a mixing tank according to predetermined proportions; carrying out hardening treatment on the mixed ash resources according to the requirements of process parameters to obtain combustion raw materials and / or calcium carbide raw materials; calcining the combustion raw materials to obtain heat energy for utilizing, and / or storing and conveying the calcium carbide raw materials into a calcium carbide feeding tank for producing calcium carbide. The method has the advantages that the ash resources generated in the production process of the calcium carbide are fully utilized, and the combustion raw materials are sufficiently combusted, so that the utilization rate of energy is maximized; flue gas generated by combustion is greatly reduced, so that the purification time of the flue gas is saved, the purification difficulty isreduced and environmental pollution is reduced; greenness, environmental protection as well as comprehensive recycling of the ash resources of the calcium carbide factory are realized.
Description
technical field [0001] The invention relates to the field of energy technology, in particular to a comprehensive recycling method and system for calcium carbide plant ash resources. Background technique [0002] Calcium carbide production enterprises use calcium carbide furnaces to produce calcium carbide, which belongs to a series of electric arc furnaces. The core theory of the calcium carbide furnace smelting is: through ionized air to form a directional high-temperature ion flow arc, convert electrical energy into heat energy, and provide a sufficiently high temperature field for the reduction reaction of lime and semi-coke. In the production of calcium carbide, the flue gas emitted by the calcium carbide furnace is the largest source of pollution. By the end of 2016, according to incomplete statistics, there were 220 domestic calcium carbide manufacturers with a production capacity of 45 million tons per year, mainly distributed in Ningxia, Inner Mongolia, Shaanxi, Gan...
