Flue gas heat radiating device for drying apparatus

Abstract

The invention relates to a fume heat abstractor used in a drying device, which belongs to the field of heating supply equipment. The fume heat abstractor used in the drying device consists of a cylindrical heat abstraction smoke box and an exhaust smoke device, wherein, the cylindrical heat abstraction smoke box consists of a first level heat abstraction smoke box and a second level heat abstraction smoke box. The first level heat abstraction smoke box is communicated with a smoke inlet pipe, and the smoke inlet pipe is communicated with the cylindrical first level heat abstraction smoke box along the direction of the tangent of the cylindrical first level heat abstraction smoke box; and the second level heat abstraction smoke box is communicated with a exhaust smoke pipe. The smoke inletpipe of the first level heat abstraction smoke box is communicated with the first level heat abstraction smoke box tangentially, the first level heat abstraction smoke box is communicated with the second level heat abstraction smoke box tangentially, the second level heat abstraction smoke box is communicated with a falling ash device tangentially. The fume enters into the first level heat abstraction smoke box tangentially and goes ahead helically along the wall of the first level heat abstraction smoke box. The detection time of the fume in the first level heat abstraction smoke box and thesecond level heat abstraction smoke box is comparatively long; therefore the heat abstraction utilization rate is high. The arrangement of a falling ash port and a falling ash device can clean away the soot effectively to lead the exhaust smoke to be clean and the effect of heat abstraction to be better.

Description

Technical field [0001] The invention relates to a flue gas heat dissipation device used for a drying device, and belongs to the field of heating equipment. Background technique [0002] Hawthorn is a medicinal and edible plant produced in China. Hawthorn has important medicinal value and has curative effects on many diseases. The medicinal hawthorn needs to be dried, and the drying of hawthorn requires a heat sink. At present, it is used for drying hawthorn. The heat dissipation device of the smoke box is a non-circular smoke box. The smoke inlet pipe of the smoke box is directly connected with the smoke box. The flue gas stays in the flue for a short time, and the dust particles in the flue gas are easy to stick to the wall of the smoke box and accumulate on the wall of the smoke box. The smoke box greatly affects the heat dissipation, so that the dust particles and heat in the flue gas are discharged into the air in large quantities, which wastes energy and pollutes the environ...

Problems solved by technology

[0002] Hawthorn is a medicinal and edible plant produced in my country. Hawthorn has important medicinal value and has curative effects on many diseases. Medicinal hawthorn needs to be dried, and the drying of hawthorn requires a cooling device. Currently, hawthorn drying uses The cooling device is a non-circular smoke box. The smoke inlet pipe of the smoke box is directly connected with the smoke box. The heat dissipation is greatly affected in the smoke box, so that a large amount of smoke particles and heat in the flue gas are discharged into the air, which not only wastes energy, but also pollutes the environment. Other food or processing fields that require drying equipment also have drying equipment have the same problem
