Vacuum powdery material drying, condensing and dedusting integrated device

Abstract

The invention discloses a vacuum powdery material drying, condensing and dedusting integrated device which comprises a vacuum dryer, and a through hot water barrel is arranged in the vacuum dryer; a condensing tower is arranged at the upper end of the vacuum dryer, an air outlet is formed in the top of the condensing tower, an ascending pipe communicated with the vacuum dryer is arranged at the upper end of the vacuum dryer, and a spraying system, a demisting system, a dew removing system and a condensing system are arranged above the ascending pipe; an inclined baffle is arranged in the condensing tower, the ascending pipe penetrates through the baffle, a circulating water layer is arranged above the baffle, and the liquid level of the circulating water layer is lower than the height of the waterproof cap. Evaporated water vapor is condensed continuously, dust is discharged through the basket type filter along with circulation of the spraying system and collected for secondary drying, the problem of dust removal blockage is solved, the water vapor condensing effect is improved, and normal operation of the vacuum drying procedure is effectively guaranteed. The method is safe and reliable, is simple and easy to operate and maintain, and can be widely popularized and applied.

Description

technical field [0001] The invention relates to the technical field of industrial dust removal, in particular to an integrated device for drying, condensation, gas and dust removal of vacuum powdery materials. Background technique [0002] Vacuum vacuum dryer is a vacuum low-temperature equipment for heating materials. It is widely used for dehydration and drying of high value-added and heat-sensitive agricultural and sideline products, chemical raw materials, etc., as well as low-temperature concentration of chemical products, removal of crystal water, and enzyme preparations. drying etc. The vacuum drying system is mainly composed of a vacuum dryer cylinder, a bag filter, a heat source system, a condenser, a buffer tank and a vacuum pump. The commonly used filter device is a bag filter. In the process of drying powdery materials under vacuum conditions, the scraper in the cylinder of the vacuum dryer stirs and churns the materials to exchange heat with the heat source. Th...

AI Technical Summary

Problems solved by technology

Due to the high humidity in the cylinder and the small dust particles, it is easy to block the bag of the dust removal device after long-term operation, affecting the drying effect and the subsequent condensation process, resulting in high energy consumption of the system, and frequent replacement of the cleaning bag increases the maintenance workload and cost. , the damp environment also affects the service life of the bag

At present, the dust removal and filtration device matched with the vacuum dryer is mainly a bag dust removal device, and the effect of electrostatic dust removal is not ideal.
