The invention discloses an environmentally-friendly production process for insoluble sulfur. The environmentally-friendly production process for insoluble sulfur is characterized by comprising a sulfur melting process, an extracting process, a water treatment process, a pulverizing process and an oil filling process. The environmentally-friendly production process for the insoluble sulfur is a method for producing high-content, high-heat-resistance and environmentally friendly insoluble sulfur. By the method, waste gas, waste residues, waste water and dust in a production process of products are sealed and recycled, disordered emission is stopped, and the environmentally friendly insoluble sulfur product which meets European Union EC specified requirements is manufactured efficiently. Theenvironmentally-friendly production process for insoluble sulfur has the advantages of simple technological process, convenience and high efficiency in production and operation and the like. 本发明公开了种不溶性硫磺的环保生产工艺，其特征在于：包括熔硫工序、萃
