Calcium carbide furnace based calcium carbide sensible heat power generation system and implementation method thereof

Abstract

The invention discloses a calcium carbide furnace based calcium carbide sensible heat power generation system and an implementation method thereof. The calcium carbide sensible heat power generation system comprises an annular heat exchange system, a steam drum (7), a steam turbine (4), a power generator (3) and a return-flow system; the annular heat exchange system surrounds the periphery of a calcium carbide furnace; the steam drum (7) is communicated with the annular heat exchange system; the steam turbine (4) is connected with the steam drum (7) through a steam inlet pipe (1); the power generator (3) is connected with the steam turbine (4); the return-flow system is connected with a steam outlet of the steam turbine (4) and the steam drum (7) and used for recycling steam exhaust to the steam drum (7). According to the calcium carbide furnace based calcium carbide sensible heat power generation system and the implementation method thereof, the structural design is reasonable, the implementation is convenient, the calcium carbide sensible heat can be effectively recycled, the environment temperature is reduced, the manual operation links are greatly reduced, the risk of work of workers is effectively reduced, and the problem that the sensible heat of calcium carbide discharged out of the furnace cannot be recycled in the prior art is solved.

Description

technical field [0001] The invention relates to the recovery and utilization of calcium carbide sensible heat, in particular to a calcium carbide furnace-based sensible heat power generation system of calcium carbide and its realization method. Background technique [0002] The production process of calcium carbide is a high energy-consuming process. The comprehensive energy consumption per ton of calcium carbide is about 1100kg standard coal and 3400 kWh of electricity. Among them, the sensible heat brought out by calcium carbide accounts for about 21% of the comprehensive energy consumption, that is, for every ton of calcium carbide produced, about 231kg ​​of standard coal heat is wasted. [0003] The current calcium carbide production process is to add carbon materials, the inlet or the pipeline at the upper end of the electric furnace to add the mixture into the electric furnace, and heat it to about 2000°C to 2200°C in an open or closed electric furnace to form calcium ...

AI Technical Summary

Problems solved by technology

[0003] The current calcium carbide production process is to add carbon materials, the inlet or the pipeline at the upper end of the electric furnace to add the mixture into the electric furnace, and heat it to about 2000°C to 2200°C in an open or closed electric furnace to form calcium carbide liquid, which is obtained from the calcium carbide furnace. Flow out from the discharge port, put it into a container made of cast steel, cool it for about 3 hours under natural ventilation conditions, break it into a certain particle size, and then load it away; This process is wasted a lot, and the sensible heat of calcium carbide products is not effectively utilized
