High-efficiency and energy-saving intensive tobacco flue-curing house

Abstract

The invention discloses a high-efficiency and energy-saving intensive tobacco flue-curing house, which comprises a heat supply chamber, a baking chamber, a hot air circulating system and an absorption type heat pump system, wherein the hot air circulating system is connected with the heat supply chamber, the baking chamber and the absorption type heat pump system sequentially by a pipeline; and the absorption type heat pump system is arranged on the top of the baking chamber. According to the high-efficiency and energy-saving intensive tobacco flue-curing house, the heat exchange efficiency and energy utilization rate are improved by utilizing a technology of performing heat exchange by a rotary air heat exchanger, a technology of preheating air required by the combustion of a hearth by recovered smoke waste heat, a technology that the recycled smoke waste heat is used as a heat source of the absorption type heat pump system and the like; a baking effect of the tobacco flue-curing house is improved by utilizing technologies of supplying air from two sides of a side wall air distribution board and exhausting the air from the center of a central air draft pipe; and a humidity-discharging effect and an energy-saving effect are improved by utilizing a technology of performing deep dehumidification and recovering humidity-discharging waste heat by the heat pump system. Therefore, the high-efficiency and energy-saving intensive tobacco flue-curing house has the characteristics of high heat exchange efficiency, high energy utilization rate, good baking effect and good humidity-discharging effect, is particularly suitable for low-cost and large-scale production, and can be widely applied to the technical field of tobacco flue-curing.

Description

technical field [0001] The invention belongs to the technical field of baking equipment, and in particular relates to a high-efficiency and energy-saving dense flue-cured room. Background technique [0002] Tobacco leaf curing is to fully display the excellent traits formed and accumulated in the whole agronomic process of tobacco, and it is a crucial technical link that determines the final quality, yield, usability value and production efficiency of tobacco leaves. With the development of science and technology and the improvement of tobacco leaf curing technology, the tobacco flue-curing room in our country is also undergoing tremendous changes. According to the structure and curing process of the flue-cured barn, it is divided into three development stages, including: traditional barn, standard barn and intensive barn. Since Johnson and others in the United States reported the "intensive tobacco leaf curing" process in 1960, the United States, Japan and other countries ...

AI Technical Summary

Problems solved by technology

However, the current dense flue-cured rooms still have the following disadvantages: 1. The heat exchange method of mechanical forced ventilation is adopted in the barn, and the heat transfer efficiency is still not high; The temperature distribution and humidity distribution in the barn are also relatively uneven, which seriously affects the final quality of the tobacco leaves; 3. The ventilation and humidity removal speed in the curing room is relatively slow, and it is difficult to remove the humidity; 4. The waste smoke discharged from the chimney and the curing process The heat contained in the discharged hot and humid air has not been recovered, and the energy utilization rate is low
