Radiation type rotary drying device for waste salt treatment

Abstract

The invention discloses a radiation type rotary drying device for waste salt treatment. The radiation type rotary drying device comprises a rotary material cylinder. A heating jacket is arranged on the outer side of the rotary material cylinder. The heating jacket and the rotary material cylinder are the same in inclination direction and inclination angle. A burner is arranged below the lower end of the heating jacket. A flame spray opening of the burner is connected with an inner cavity of the heating jacket. A heat radiation plate is arranged in the heating jacket. A heat jet opening of the burner directly faces the heat radiation plate. Compared with the prior art, the radiation type rotary drying device has the following beneficial effects that the energy of flames is absorbed by the heat radiation plate, and then the heat is transmitted to the rotary material cylinder in a heat radiation manner, so that the rotary material cylinder is uniformly heated, and the temperature is quite constant; the heating jacket is fixedly arranged, and a rotary cylinder body rotates in the heating jacket, so that the heating of the whole rotary cylinder body is consistent in the radial direction; and the flue gas flow speed can be guaranteed due to the special design of the shape of the heating jacket, the thickness of a stagnant layer is reduced, and the heat transfer efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of chemical waste treatment and regeneration, in particular to a radiation type rotary drying device for waste salt treatment. Background technique [0002] Industrial waste salt also contains a large amount of organic or inorganic impurities, which cannot be directly used as industrial raw material salt, let alone for food or medical use, and most manufacturers pile it up. The long-term storage of this kind of salt not only occupies a large amount of land, but also poses a huge threat to the environment. The salt and impurities are easily lost, salinizing the surrounding soil, endangering the surrounding vegetation, and polluting the surrounding rivers, water sources, and rice fields. Therefore, using appropriate technology and equipment to recycle this industrial waste salt as industrial raw material salt can not only eliminate pollution, make full use of precious salt resources, but also generate profits ...

AI Technical Summary

Problems solved by technology

It is necessary to heat the waste salt to a very high temperature to ensure that as much organic matter as possible is decomposed or vaporized, but the fine-grained waste salt is prone to melting during the heating process, and once it melts, serious agglomeration will occur , seriously affecting the subsequent processing steps

The temperature control is too low, and the effective organic matter removal effect cannot be achieved. Therefore, how to increase the heating temperature as much as possible in this process and ensure the stability and uniformity of the heating temperature is a very important issue.
