Method for extruding and compounding calcium carbide smelting material through calcium carbide furnace tail gas and dust

Abstract

The invention relates to a method for extruding and compounding calcium carbide smelting material through calcium carbide furnace tail gas and dust. The method comprises the steps of mixing calcium carbide furnace tail gas and dust and coal tar according to weight ratio of 80 to 85 percent : 20 to 15 percent, sufficiently stirring the calcium carbide furnace tail gas and dust and the coal tar, and performing extrusion forming. The method directly utilizes the calcium carbide furnace tail gas and dust to extrude and compound the calcium carbide smelting material, ensures that the calcium carbide furnace tail gas and dust can be sufficiently utilized in the calcium carbide furnace smelting, achieves the purposes of high solid waste use ratio, cost reducing, energy saving and environment protection, and simultaneously is simple in production process, low in technical requirements, small in energy consumption, low in cost, and obvious in economic benefit.

Description

technical field [0001] The invention relates to the technical field of calcium carbide smelting, in particular to a method for extruding and synthesizing raw materials for calcium carbide smelting by using dust from the tail gas of a calcium carbide furnace. Background technique [0002] Calcium carbide is a basic organic chemical raw material. Acetylene produced from it can replace petroleum products to produce a series of thousands of organic products such as acetic acid, vinyl acetate, polyvinyl chloride, polyvinyl alcohol, and acetylene carbon black. In the calcium carbide industry across the country, whether it is a fully enclosed calcium carbide furnace, an internal combustion closed calcium carbide furnace or an open calcium carbide furnace, the exhaust gas volume is large and the dust concentration is high. Many calcium carbide factories have spent a lot of manpower and material resources on exhaust gas dust removal devices. Very little, most of the calcium carbide f...

Problems solved by technology

In the calcium carbide industry across the country, whether it is a fully enclosed calcium carbide furnace, an internal combustion closed calcium carbide furnace or an open calcium carbide furnace, the exhaust gas volume is large and the dust concentration is high. Many calcium carbide factories have spent a lot of manpower and material resources on exhaust gas dust removal devices. Very little, most of the calcium carbide furnace dust is seriously exceeding the standard

At present, there is no effective utilization method for the settled calcium carbide furnace tail gas dust, and the method of landfill and soil covering is generally adopted, which not only wastes resources, but also easily pollutes groundwater and the environment, becoming unusable industrial solid waste, and affecting the continuity of the calcium carbide industry. healthy growth
