Embodiment Construction

[0029] The method for collecting and reusing waste heat in the liquid calcium carbide solidification process of the present invention is as follows:

[0030] The calcium carbide furnace 1 emits high-temperature liquid calcium carbide through the furnace nozzle 2, and the calcium carbide flows into the calcium carbide pot 3. The calcium carbide pot 3 is placed in advance on the circular transport trolley 5 connected head to tail, and the circular trolley 5 is jointly dragged by the driving device 4 and 7 to walk. Every time a pot is filled with calcium carbide, the trolley moves forward one step, that is, a pot position length. The trolley driving device A4 and the trolley driving device B7 utilize hydraulic transmission to act intermittently and stop at one step, thereby realizing the effect of continuous calcium carbide pot filling. The annular transport trolley 5 carries the calcium carbide pot 3 through the waste heat collection compartment 15. After the heat is absorbed b...

Abstract

The invention relates to a waste heat collecting and recycling method in the solidification course of liquid calcium carbide, which comprises the following steps: the liquid calcium carbide which is emitted from the mouth of a calcium carbide furnace flows into calcium carbide pots which are placed on an annular transportation trolley one by one; the annular transportation trolley loaded with thecalcium carbide pots passes through a calcium carbide waste heat collecting box and calcium carbide exchanges heat with water; and the generated hot water is transmitted to a water storage tank through a water discharge pipeline and finally transmitted to a user pipe network through the pipeline. The method provided by the invention realizes recycle of the waste heat in the production course of the calcium carbide and has the obvious effects of saving the energy sources, lowering the production cost, improving the production environment, realizing clean production.

Description

technical field [0001] The invention relates to the technical field of calcium carbide production, in particular to a method for collecting and reusing waste heat in the solidification process of liquid calcium carbide. Background technique [0002] The calcium carbide produced by calcium carbide chemical companies is naturally cooled from liquid to solid and then transferred to subsequent production processes. At present, the annual output of a large calcium carbide furnace has reached more than tens of thousands of tons. The transformation of such a large amount of high-temperature calcium carbide from liquid to solid is mainly through natural cooling to room temperature, and the heat loss is very large. As a result, the space required for calcium carbide cooling is getting larger and larger, and the transportation cost is also increasing. At the same time, the natural cooling process of calcium carbide will have a certain impact on the environment and climate, such as th...
