Description

white carbon black continuous drying device

Technical Field

The utility model relates to an electrical equipment technical field, concretely relates to continuous drying device of white carbon black.

Background

The white carbon black is white solid or powder, and has the characteristics of porous, light and soft solid, strong adsorbability, insolubility in water and the like. Can be used in the technical fields of glass, ceramics and refractory materials, metallurgy, architecture, chemical industry, machinery, electronics, rubber, plastics, coating, medicine and the like, and is an important raw material for scientific research.

the white carbon black is mostly dried by adopting a spray drying method, the spray drying is to convey pulped white carbon black feed liquid into an atomizer on the upper part of a drying tower by a pump, the feed liquid is dispersed into uniform and fine fog drop groups under the action of the atomizer, hot air enters the upper part of the drying tower through a hot air distributor, and the air is rapidly subjected to heat and mass exchange after contacting with the fog drop groups, so that solid powder is formed in a short time. However, the moisture content of the white carbon black obtained by the spray drying method is controlled within the range of 4-8 wt%, the white carbon black can only be used for general purposes in the rubber industry, and the moisture content of some white carbon black for special purposes is required to be lower than 2 wt%. Because a large amount of hydroxyl exists on the surface of the white carbon black molecule, the water absorption is very strong, and a large amount of water vapor is mixed in the tail gas of the primary spray drying, the white carbon black powder obtained by the primary spray drying can easily absorb water from the tail gas, so that the white carbon black with the water content lower than 2wt% is difficult to form, and the requirements of partial special industrial materials can not be met. Therefore, it is necessary to develop a white carbon black drying apparatus having a secondary drying function.
