Problems solved by technology

[0003] Example 1 of the prior art discloses a method for preparing insoluble sulfur, mainly for the preparation of insoluble sulfur for rubber tires, the cooling medium is liquid nitrogen, and the process flow is melting, atomization, polymerization, quenching, and separation and packaging. The molten sulfur liquid is centrifugally atomized by the atomizer into sulfur droplets with an average particle size of 20 μm. In order to meet the above technical requirements, it is necessary to ensure that the atomizer can still work reliably at high temperatures (centrifugal atomization requires the atomizer to rotate at high speed ), as we all know, according to the high-temperature production environment of 280-400 ° C, it is difficult to ensure the normal operation of the atomizer and the particle size requirements of the sulfur droplets in mass industrial production; the second example of the prior art discloses the preparation method of insoluble sulfur, The main innovation point is to use normal pressure or low pressure equipment to complete the preparation of insoluble sulfur. The main production devices are heating and stirring containers, superheaters, spray guns, atomization towers and heat exchangers, which are the closest technical solutions to the present invention, but No details of the production facility were disclosed

Abstract

The invention relates to the technical field of volatile organic compoundwaste gas treatment, in particular to a device for an evaporation process for preparing insoluble sulfur. The device is characterized by comprising a saturated vapor heating kettle component, an overheater, anoverheatingsulfur vapor intermediate tank and a sulfur powder storage tank. The device adopts a two-section heating mode to prepare overheatingsulfur vapor, namely firstly performs heating to reach a molten state (liquid phase), then performs reheating to obtain the overheatingsulfur vapor (gas phase), and obtains a sulfur polymer after quenching. A transpirationconvection tube and a circulating convection tube are designed by utilizing a transpiration principle and connected with heating devices of low-temperature and high-temperature sections so as to complete the technological process.

Description

technical field [0001] The invention relates to the technical field of insoluble sulfur, in particular to a device for the evaporation process of preparing insoluble sulfur. Background technique [0002] Insoluble sulfur (IS), also known as polymeric sulfur, also known as μ-type sulfur, refers to sulfur insoluble in carbon disulfide. It is a long-chain polymer of sulfur and is chemically and physically inert. Since the solubility of ordinary sulfur in rubber is 1%, the amount of ordinary sulfur in rubber exceeding its dissolved part will spray out the surface after the rubber is cooled, that is, blooming. Blooming will affect the viscosity between semi-finished parts and adversely affect the vulcanization uniformity of the product. Therefore, insoluble sulfur should be used when the amount of sulfur is high. Insoluble sulfur is insoluble in rubber and is only uniformly dispersed in the rubber compound. The cross-linking point is uniform, and the rubber vulcanized by it has ...
