Embodiment 1

[0048] The feeder is sealed with the high temperature solid inlet of the heat preservation conveying chute. The temperature resistance of the feeder and the high temperature conveying chute is above 900 ℃ to ensure the continuous and stable feeding of the high temperature solid into the conveying chute, the high temperature solid inlet and the high temperature solid outlet They are installed at both ends of the high-temperature conveying chute, and the feeding process is controlled by the feeder. The high-temperature solids after removing the powder material enter the high-temperature solid warehouse with insulation function through the high-temperature solid outlet along the conveying plate, from the inlet to the outlet The temperature drop of the material at the material port is less than 50℃.

[0049] The conveying corridor and the powder corridor are respectively arranged on both sides of the conveying material board, the height ratio of the conveying corridor and the powder m...

Abstract

The invention provides a high-temperature solid conveyor device comprising a feeding machine, an insulation conveyor chute, a powder bin and a high-temperature solid bin. High-temperature solid particles are screened through a material conveying plate in the insulation conveyor chute, and the solids therein enter the high-temperature solid bin; the powder enters the powder bin through a powder outlet; not only the classification and removal treatment of the power can be achieved in the material conveying process, and the power is prevented from entering a calcium carbide furnace, thereby affecting the operation of the calcium carbide furnace, but also the conveyor device has a thermal insulation function, and the sensible heat loss of the high-temperature solids is reduced; and the energyconsumption in the calcium carbide production process and the carbon emission are reduced.

Description

Technical field [0001] The invention belongs to the field of chemical industry, and particularly relates to a manufacturing process of calcium carbide, in particular to a high-temperature solid conveying device in the calcium carbide production process. Background technique [0002] Calcium carbide, also known as calcium carbide, is an important basic chemical raw material, mainly used for the production of acetylene gas, but also for organic synthesis and oxyacetylene welding. With the growth of the total economy and the improvement of people's living standards, domestic demand for downstream products of calcium carbide such as polyvinyl chloride, vinyl acetate / polyvinyl alcohol, and lime nitrogen will increase steadily. The shortage of petroleum resources in my country and the relatively abundant coal resources determine that the calcium carbide industry still has room for development in meeting downstream demand. The medium and long-term trend of my country's calcium carbide m...
