Problems solved by technology

In the constant-speed drying stage, the drying efficiency of the wet material using the internal heating fluidized bed is higher; however, in the slow-down drying stage, the movement state of the wet material has little effect on its dehydration rate, and the energy consumption in the "fluidized" state higher question

Abstract

The invention belongs to the field of drying devices; in particular, it relates to a steam closed-circuit pulsating moving combined drying system, the structure of which is: the pulsating moving bed drying equipment is a vertical structure, including a shell, a feeding part and an air outlet arranged on the shell , a hopper and a pulsating drying unit and a moving bed drying unit set in the housing. The air outlet is connected to the dust collector, induced draft fan, and waste heat recovery device in sequence, the waste heat recovery device is connected to the steam reheater, the steam reheater is connected to the pulsating air distribution device, and the material cooler is connected to the discharge hopper. And between the pulsating drying unit and the moving bed drying unit and below the moving bed drying unit, there are pulsating air distribution devices with the air distribution outlet facing the feeding part. The above-mentioned system realizes the efficient and rapid dehumidification of wet materials in the constant-speed drying stage and the low-energy-consuming deep dehumidification in the falling-speed drying stage, effectively reducing the energy consumption of the production unit product.

Description

technical field [0001] The invention belongs to the technical field of drying; in particular, it relates to a steam closed-circuit pulsating moving combined drying system. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] In industrial production, there are many types of high-humidity materials that contain moisture that needs to be reduced to a lower moisture content. Conventional equipment and methods for drying high-humidity materials use: high-temperature hot flue gas as a heat source to directly heat materials, (such as air, nitrogen, flue gas, etc.) The exhaust gas of wet steam will cause a large load on the treatment system and high energy consumption,...
