Vertical and split type drying oven

Abstract

The invention discloses a vertical and split type drying oven in the technical field of equipment. The vertical and split type drying oven comprises a drying box and a hot-blast stove with a combustor at the bottom, an igniter is located outside the hot-blast stove and communicated with the combustor; the hot-blast stove and the drying box are arranged in parallel; a fan support for dividing the hot-blast stove into a preheating chamber and a heat exchange chamber is arranged inside the hot-blast stove; the fan support is provided with an axial flow fan; heat distribution pipelines are further arranged inside the hot-blast stove and distributed in a Z shape; the heat distribution pipelines comprise a heat exchange pipeline located in the heat exchange chamber and a preheating pipeline located in the preheating chamber; the heat exchange pipeline is communicated with the preheating pipeline; an air inlet with an air door is formed in the top of the hot-blast stove; an air outlet is formed in the lateral wall of the lower end of the heat exchange chamber; a hot air inlet is formed in the lateral wall of the lower end of the drying box; the air outlet is communicated with the hot air inlet. The vertical and split type drying oven improves the heat exchange efficiency, so that the beneficial effect of rapidly and efficiently heating air is achieved.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a vertical split drying furnace. Background technique [0002] At present, most of the general drying furnaces at home and abroad adopt a cylindrical integral structure, which has a short heat exchange process, high exhaust gas temperature, small heat exchange area, large volume, and low thermal efficiency; The hot air outlet is connected to the air inlet of the drying furnace for waste heat recovery. This way the waste heat recovery route is long and the loss of heat is large. The equipment adopts a vertical structure. As the drying furnace will accumulate smoke and dust in the flue with the passage of time, it will affect the heat transfer capacity of the tube wall and reduce the heat transfer efficiency. Contents of the invention [0003] The present invention aims at the above-mentioned existing technical problems, and provides an energy-saving and high-efficiency...

Problems solved by technology

[0002] At present, most of the general drying furnaces at home and abroad adopt a cylindrical integral structure, which has a short heat exchange process, high exhaust gas temperature, small heat exchange area, large volume, and low thermal efficiency; The hot air outlet is connected to the air inlet of the drying furnace for waste heat recovery. In this way, the waste heat recovery route is long and the loss of heat is large.

The equipment adopts a vertical structure. As the drying furnace will accumulate smoke and dust in the flue with the passage of time, it will affect the heat transfer capacity of the tube wall and reduce the heat transfer efficiency.
