Embodiment Construction

[0015] The present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.

[0016] The shape of the heat exchange cavity of the present invention can be a zigzag or wave-shaped structure. The following is an example of a zigzag structure of the heat exchange cavity, such as Figure 1-3 As shown, a pulverized coal drying and preheating device with vertical partition heat exchange includes an air intake pipe 1, an exhaust pipe 3, a heat exchange chamber 2, a shell 4 and 5 thin-walled plates, and the shell 4 is perpendicular to the ground Installation, the two ends of the 2 heat exchange chambers are respectively provided with 1 intake pipe and 3 exhaust pipes, at least two of the 2 heat exchange chambers are arranged inside the shell 4, and there is a gap between the heat exchange chamber and the heat exchange chamber. There are material channels, and the outer surface of the heat exchange chamber 2 is welded with thin-walled pl...

Abstract

The invention discloses a vertical type powdered coal drying preheating device based on partition wall heat exchange. The vertical type powdered coal drying preheating device comprises an air inlet, an air discharge pipe, heat exchange cavities, a shell and a thin wall plate. The vertical type powdered coal drying preheating device is characterized in that the shell is arranged perpendicular to the ground; two ends of each heat exchange cavity are respectively provided with the air inlet pipe and the air discharge pipe, at least two heat exchange cavities are both arranged in the shell, a material channel is reserved between the heat exchange cavity and the heat exchange cavity, and the outer surface of the heat exchange cavity is welded on the thin wall plate. The vertical type powdered coal drying preheating device based on partition wall heat exchange, which is disclosed by the invention, is simple in structure and can be used for increasing the radiating area, changing the flow state of a coal material and enhancing the heat exchange effect.

Description

technical field [0001] The invention belongs to the technical field of pulverized coal drying and preheating, in particular to a pulverized coal drying and preheating device for heat exchange with vertical partition walls, which can realize drying, dehydration and preheating of pulverized coal materials. Background technique [0002] Pulverized coal is a common form of coal and is widely used in the coal chemical industry. In many cases, such as pulverized coal pyrolysis or pulverized coal is used as fuel, it is often necessary to dry and dehydrate it and preheat it. The commonly used heat source is flue gas, hot air or steam with a certain temperature. At present, the existing drying and preheating methods are basically divided into two categories: (1) direct heat exchange, that is, the heat medium is in direct contact with the pulverized coal, and the heat exchange is realized through heat conduction, so as to achieve the purpose of drying and dehydration or heating. The...
