Problems solved by technology

[0003] The generation of calcium carbide powder has the following major problems: first, the dust of calcium carbide powder is very serious, which brings great difficulties to the operation of workshop workers and reduces work efficiency; second, the processing cost is high, 50 yuan / ton, Yili Chemical The annual direct treatment cost reaches 300,000 yuan; third, the calcium carbide powder becomes solid waste accumulation and pollutes the environment; fourth, if the calcium carbide powder is recycled and reused, the calculation is based on 3,000 yuan / ton of calcium carbide, and the recycling of the recycled calcium carbide powder Calculating that the gas generation is 20% of the gas generation of calcium carbide, it can bring economic benefits of about 3.9 million yuan to Elion Chemical every year
At present, no technology has been found to control calcium carbide powder, the source of dust generation

Abstract

The invention provides a calcium carbide powder dust forming inhibitor, and a preparation and an application thereof. The calcium carbide powder dust forming inhibitor mainly contains calcium carbonate. The calcium carbide powder dust forming inhibitor can inhibit the fly of calcium carbide dusts in air, cleans the work environment, improves the work efficiency, and enables recovered calcium carbide to be molded and reused.

Description

technical field [0001] The invention belongs to the field of environmental protection dust suppression and solid waste utilization, and in particular relates to a calcium carbide powder dust suppression molding agent and its preparation and application. Background technique [0002] In 2012, the national calcium carbide production of PVC reached 9.81 million tons, and the amount of calcium carbide required for one ton of PVC was 1.45-1.5 tons. The annual calcium carbide consumption reached 14.2245-14.715 million tons, and the calcium carbide consumption was very large. The amount of calcium carbide powder produced during the production of acetylene from calcium carbide is 1.5%-2.5%. There are probably two sources of calcium carbide powder: the process of crushing calcium carbide blocks and the process of conveying calcium carbide fragments by belts. Elion Chemical produces about 6,000 tons of calcium carbide powder every year. [0003] The generation of calcium carbide pow...
