Closed calcium carbide oven capacitance-increasing process

Abstract

The invention discloses a capacity adding craft method of the closed calcium carbide furnace, including a furnace body and the furnace lid of the top furnace, the furnace bottom installs the released mouth, the lid installs the electrode, feeding mouth, the electrode connects to the electric furnace transformer with the soft water cables, short network, the top of feeding mouth connects to a ring feeding machine, the capacity adding method of the closed calcium carbide furnace is: increasing the current rating of the first current and the secondary current, the capacity of electric transformers increased to each not less than 10,000 KVA; the height of lid increased to 1,300 to 1,500 MM. the low pressure outline port of the secondary short net in the short net changed to the intercross outline port. Reduced the distance between the electric furnace transformer and the wall of the electric furnace workshop and shortened the length of short network copper pipe. The invention increased the load, production and extended the use life of the furnace transformer; after the lid being heightened, it plays a stabilizing furnace pressure and extends life expectancy effect.

Description

technical field [0001] The invention relates to a capacity-increasing process method of a calcium carbide furnace, in particular to a capacity-increasing process method of a sealed calcium carbide furnace. Background technique [0002] Calcium carbide, chemical name calcium carbide (CaC 2 ), pure calcium carbide is almost colorless transparent crystal, density 2.22, insoluble in solvent. The so-called calcium carbide usually refers to industrial calcium carbide, which is produced by heating quicklime and coke in a calcium carbide furnace through an electric furnace. Calcium carbide has the following physical and chemical properties: (1) Physical properties: the higher the quality of calcium carbide, the smaller the relative density, and vice versa. (2) Chemical properties: Acetylene can be produced by adding excess water to calcium carbide, polyvinyl chloride can be produced by adding excess water to calcium carbide; if calcium carbide (CaC 2 ) is excessive, when calcium ...

AI Technical Summary

Problems solved by technology

[0003] In view of the low height of the furnace cover of the existing sealed calcium carbide furnace, it is easy to generate a large branch current and powder in the furnace, so that the pressure in the furnace is too large and the temperature of the material surface is high; the purpose of the present invention is to provide a Increase the height of the furnace cover, increase the diameter of the network copper pipe, change the secondary short network low-voltage outlet port of the short network to a cross outlet port, and increase the capacity of the electric furnace transformer to 10000KVA×3 The capacity increase process method of the sealed calcium carbide furnace
