A forced heat recovery energy-saving tobacco flue-cured room

Abstract

The invention discloses a forced heat recovery type energy-saving tobacco curing barn which comprises a tobacco loading chamber (1) and a heating chamber (2), wherein the tobacco loading chamber (1) is separated from a heating chamber (2) through a heat insulation wall (13); humidity exhaust outlets (3) communicated with the tobacco loading chamber (1) are formed in two vertex angle positions of the heat insulation wall (13); an air inlet (4) is formed in the heating chamber (2); total heat exchangers (6) are respectively arranged on the humidity exhaust outlets (3) through heat insulating tubes (5) in a connecting manner; a fresh air outlet (61) of each total heat exchanger (6) faces the air inlet (4); fans (7) are respectively arranged on the fresh air outlets (61) and humidity exhaust gas outlets (62) of the total heat exchangers (6). The total heat exchangers are used for performing heat exchange on fresh air and hot humid air exhausted from the humidity exhaust outlets, and preheated fresh air blows towards the air inlet from the fresh air outlets, so that heat recovery of humidity exhaust gases is realized, the loss of heat in the humidity exhaust process is avoided, and electric energy is saved.

Description

technical field [0001] The invention relates to a forced heat recovery energy-saving tobacco curing room, which belongs to the technical field of energy-saving baking equipment. Background technique [0002] As the second largest tobacco leaf producing area in the country, Guizhou Province has good ecological resource advantages and is a typical representative area of ​​middle-flavor tobacco leaves. Guizhou tobacco leaves have become an indispensable and important raw material for well-known Chinese cigarette brands. From 5.3 million tons to 7.0288 million tons in 2010, accounting for about 15% of the national total, the two tobacco industries have become the pillar industries of Guizhou Province. [0003] At present, many tobacco-producing areas in Guizhou still use traditional coal-fired barns. This type of barn not only consumes a lot of energy and is not energy-saving, but also causes serious environmental pollution during the roasting process, which does not meet the re...

Problems solved by technology

[0003] At present, many tobacco-producing areas in Guizhou still use traditional coal-fired barns. This type of barn not only consumes a lot of energy and is not energy-saving, but also causes serious environmental pollution during the roasting process, which does not meet the requirements of energy conservation and environmental protection.

Although many areas are currently promoting heat pump energy-saving barns, there is also energy waste in such barns

During the drying and dehumidification process of traditional coal-fired barns and ordinary heat pump barns, a large amount of heat in the barns will be discharged, resulting in great waste
