Problems solved by technology

To completely dry 1t of calcium carbide slag with 35% water content, 350kg of water needs to be evaporated, and 539kcal of heat is needed to evaporate only 1kg of water. At the same time, the drying exhaust gas will take away a lot of heat. Large-scale dust removal equipment must be installed, and the investment in fixed assets is large. , the unit power consumption is also high, so the cost of carbide slag drying is very high

Abstract

The invention relates to industrial grade calcium hydroxide production equipment which comprises carbide slag bin, a lime bin, a feeding screw reamer, a dual-shaft stirrer and a digestion bin. The carbide slag bin and the lime bin are communicated with the feeding screw reamer. An outlet of the feeding screw reamer is communicated with a dual-shaft stirrer feeding inlet of the dual-shaft stirrer. A dual-shaft stirrer discharging outlet of the dual-shaft stirrer is communicated with the digestion bin. A discharging outlet is formed in the lower portion of the digestion bin. The digestion bin is sealed. According to the industrial grade calcium hydroxide production equipment, a traditional calcium hydroxide production technology is changed, a large amount of industrial waste carbide slag is utilized, calcium oxide is added to be mixed and stirred, the novel industrial grade Ca(OH)2 production technology is formed through procedures such as digestion of the digestion bin, a large amount of carbide slag can be utilized with low cost, the technology is widely applied to projects such as power plant desulfuration, and the technology is of special significance in China as the world first calcium carbide production country.

Description

technical field [0001] The invention relates to an industrial grade calcium hydroxide production equipment and a production process thereof, belonging to the technical field of chemical machinery. Background technique [0002] The traditional production process of calcium hydroxide is to use high-grade limestone CaC0 3 After high temperature calcination, it is decomposed into calcium oxide Ca0 and calcium dioxide CO 2 , calcium oxide CaO plus water H 2 0 produces Ca(OH) 2 , After drying, it becomes industrial grade calcium hydroxide. The process is relatively complex, requiring several processes such as calcination, hydration, and drying. The investment in equipment is relatively large, the production cost is relatively high, and the production capacity is also greatly limited due to the constraints of production equipment. [0003] The main component of carbide slag is Ca(OH) 2 , as an industrial waste for the production of calcium carbide, calcium carbide slag can bec...
