The electric time production enterprise uses the calcium carbide furnace to produce calcium carbide, the calcium carbide furnace is used as main equipment for producing the calcium carbide, and furnace burden is melted due to high temperature emitted by electric arc in the furnace to generate the calcium carbide. The theoretical core of the calcium carbide furnace is as follows: the air is ionized to form directional high-temperature ion flow electric arc, electric energy is converted into heat energy, and a high enough temperature field is provided for the lime and semi coke to perform reduction reaction. In calcium carbide production, flue gas discharged by a calcium carbide furnace is the largest pollution source. By the end of 2018, according to incomplete statistics, the capacity of 240 domestic calcium carbide production enterprises reaches 5000 million tons per year, and the production is mainly distributed in Ningxia, inner Mongolia, Shanxi, Gansu, Qinghai, Xinjiang and the like. A large number of calcium carbide furnaces generate huge amounts of solid particle wastes such as dust removal ash, purification ash, semi coke powder, lime powder and the like every day. For example, calcium carbide enterprises producing 100 ten thousand tons annually produce 5-7 ten thousand tons of purified ash each year, and calcium carbide plants in China produce 225-. The main treatment modes of the powder such as the purified ash and the like generated by the calcium carbide plant are burying, stacking, burning and the like.

The existing incineration mode is to mix powder directly into dust, purified ash and the like in proportion and input the mixture into a fluidized bed furnace for incineration to obtain energy. However, the heat energy generated after incineration is not fully utilized to cause resource waste, for example, in the calcium carbide furnace purification incineration equipment put into use in 2018 years of production in our factory, the original dispersed calcium carbide furnace purification ash and the dedusting ash are concentrated into the purification ash storage bin through a pneumatic conveying system, the dedusting ash in the ash storage bin is completely conveyed to a fluidized bed furnace to be incinerated in harmless treatment, the available heat of the dedusting ash is utilized, but the available heat utilization rate is low, and the drying of the blue carbon in the later period is polluted, so that the quality of the blue carbon is reduced, and certain economic loss is caused.
In addition, the existing calcium carbide furnace purification ash and dust removal treatment equipment, such as chinese patent CN110081434A, discloses a calcium carbide furnace purification ash treatment equipment, which, although it is disclosed that air is used as a medium for drying semi-coke, does not fully utilize the dust removal ash and semi-coke powder, the efficiency of the heat exchanger and air exchange process is low, the drying quality cannot be controlled, and most importantly, the heat in the heated air cannot be reused or reused, resulting in a large amount of waste of resources.
