A material heating or drying device and calcium carbide production equipment

Abstract

The invention provides a calcium carbide production process and a calcium carbide production device. The process comprises the following steps: (1) feeding raw materials into a calcium carbide furnace by a feeding device; (2) enabling the raw materials to react in the calcium carbide furnace to generate liquid calcium carbide; (3) discharging the liquid calcium carbide by the calcium carbide furnace and transporting the liquid calcium carbide into a heat collecting device for collecting waste heat of the liquid calcium carbide; and (4) transporting the waste heat of the liquid calcium carbide, collected by the heat collecting device to the feeding device by a transporting device, and pre-heating the raw materials. By using the production process, electricity consumed in the calcium carbide furnace in the calcium carbide production process can be greatly reduced, so that the energy consumption is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to a material heating or drying device and calcium carbide production equipment. Background technique [0002] At present, in the production of building materials, metallurgy and other industries, drying or heating devices are widely used. The existing vertical drying towers with better heating or drying effects are mostly used for drying materials with a certain humidity or particle size. Drying, the Chinese invention patent with the notification number CN1726377A discloses a heating or drying device for particulate materials. The heating and drying device includes an inner shell and an outer shell. There is a blanking gap between the inner and outer shells. The side wall of the outer shell is also provided with a perforated part, and the air flow enters through the perforated part of the side wall of one shell and flows out from the perforated part of the other shell. The direction makes the material heated evenly, but the airf...

[0002] At present, in the production of building materials, metallurgy and other industries, drying or heating devices are widely used. The existing vertical drying towers with better heating or drying effects are mostly used for drying materials with a certain humidity or particle size. Drying, the Chinese invention patent with the notification number CN1726377A discloses a heating or drying device for particulate materials. The heating and drying device includes an inner shell and an outer shell. There is a blanking gap between the inner and outer shells. The side wall of the outer shell is also provided with a perforated part, and the air flow enters through the perforated part of the side wall of one shell and flows out from the perforated part of the other shell. The direction makes the material heated evenly, but the airflow hardly flows to the bottom of the lower air port. Therefore, the material will be heated unevenly in the up and down direction, which greatly affects the heating and drying effect of the material.
