Problems solved by technology

Chinese patent 201310511371.1 and Chinese patent 201310511388.7 mention the preparation of insoluble sulfur by means of atomization, but it is only a description of the process, and no specific reaction device is mentioned
[0009] In addition, the quenching of the liquid flow is basically pouring or dripping, and the quenching effect is poor, resulting in a low conversion rate, which is why the content of insoluble sulfur produced by the melting method is lower than that of the gasification method.

Abstract

The invention discloses a spray reaction device for of insoluble sulfur, and relates to the technical field of preparation equipment of insoluble sulfur for rubber tires and rubber products. The sprayreaction device mainly comprises a melting system, a feeding system, a high-temperature reaction furnace, a cooling chamber, a separation system, a gas analysis system, a cooling system, a pressure balance system and a discharging system. According to the invention, inert gas is adopted to effectively reduce oxidation of sulfur and improve product quality; a quenching section process effectivelyrestrains the reverse reaction, so that the content of insoluble sulfur in a product is directly influenced; insoluble sulfur is obtained by adopting a low-temperature melting reaction method, so thatthe process is environment-friendly; and the spray reaction device can save resources and reduce cost, and has good market prospect.

Description

technical field [0001] The invention relates to the technical field of equipment for preparing insoluble sulfur for rubber tires and rubber products, in particular to a spray reaction device for preparing insoluble sulfur in a closed loop. Background technique [0002] Spray reaction equipment is an advanced new type of high-efficiency process equipment. It uses an atomizer to atomize solutions, emulsions, pastes, and suspensions. The atomized droplets have a large surface area. Under atmospheric conditions, the materials are dried, decomposed or cracked to produce powdered products that meet the requirements or new materials. At present, it is widely used in liquids, suspensions and viscous fluids in petrochemical, aviation and military industries, such as superconducting materials, lithium iron phosphate, graphite, propellants, negative electrode materials, petroleum catalysts and medicines; it can also be used in lithium batteries Materials, intermediates and inorganic s...
