Description
Technical Field
The invention belongs to a tobacco leaf baking system, in particular to a tobacco leaf baking system which uses clean energy as a heat source and adopts air internal circulation.
Background
Since the 21 st century, with the rapid development of modern tobacco agriculture in China, each link of tobacco production is operated at high efficiency. The reduction of labor, cost and efficiency in tobacco production is an urgent need and a main task in the tobacco production at present. The tobacco leaf baking is used as the final link and the most important link for determining the quality and the yield in the production of flue-cured tobacco, although the development and the popularization of a bulk curing barn and a baking process promote great progress in China in the aspect of tobacco leaf baking, a plurality of problems still exist in the practical application:
the existing curing barn still occupies a large proportion of heat supply due to coal combustion, although a large number of scholars have studied on clean energy heat supply before, the existing curing barn is limited by the baking process, the current technical development situation, the technical cost and the like, so that clean energy is difficult to obtain on heat supply of the bulk curing barnLarge-area popularization and application;
in the aspect of dehumidification, the dehumidification mode of strong dehumidification is used, so that not only is a large amount of energy consumption loss caused in the dehumidification process, but also the proportion of superior tobacco leaves and the tobacco fragrance of the tobacco leaves are reduced;
in the aspect of control, due to the limitations of the whole structure and the baking process of the baking system of the coal-fired bulk curing barn, the existing control system can only realize semi-automation and automation, and has great requirements on workers, especially tobacco growers with abundant experience. The advanced baking system and the baking process can fully show the excellent properties of the mature tobacco leaves, increase the yield and income and realize the use value of the tobacco leaves.
At present, the domestic tobacco leaf baking system has a large proportion occupied by fire coal in heat supply, in the tobacco leaf baking process, the coal consumption required for baking 1kg of dry tobacco is about 1.5-2.0 kg, the theoretical heat consumption required for discharging 1kg of water is about 2559.5-2580.3 kJ, the water content of fresh tobacco leaves in various places of China is more than 80-90%, the theoretical coal consumption required for discharging 1kg of water is only 0.423-0.952 kg calculated by the low basal calorific value 20809kJ/kg of coal, therefore, the actual coal consumption required for discharging 1kg of water in the tobacco leaf baking process is 2.778-4.505 times of the theoretical value, the heat efficiency of a baking room is only 22.2% -36.0%, and the ineffective energy consumption is high. Not only does this result in the quality of the flue-cured tobacco leaves being affected by insufficient combustion of fossil fuels, hysteresis, and uneven temperature rise and stabilization, but also the waste of fuels due to too high ineffective energy consumption and the emission of a large amount of SO2、CO2、NO2And pollutants such as particulate matters cause various problems of environmental pollution, so that domestic researchers have begun to explore researches on heat supply of bulk curing barn by biomass energy, solar energy, air source heat pump units and the like.
The solar energy-saving solar energy water heater has wide territorial area and abundant solar energy resources, and is about 3348-8371 MJ/(m)2A) between each other, about 5860 MJ/(m) on a national average2∙ a). Since the 21 st century, TaiThe solar energy medium-low temperature heat utilization technology has made great progress, is the most widely applied solar energy utilization technology with the highest degree of commercialization at present, and is mature in solar energy low-temperature heat utilization technology in China. At present, China is the country with the largest solar heat collector yield and sales in the world, so that the solar heat collector has a good application foundation for supplying heat by using solar energy in the intensive flue-curing barn in the tobacco area with rich solar energy resources. The heat pump is a refrigeration system, heat is released by condensing a refrigerant in a condenser to supply heat, the heat pump is a high-efficiency energy-saving device, the technology is mature, the performance is reliable, and the heat pump is widely applied, wherein the air source heat pump is the most economical and convenient in the heat pump technology, and tobacco leaf baking is generally carried out in summer and in the beginning of autumn, at the moment, the external temperature is high, and the heat pump is in the time of the highest energy efficiency ratio, so that the tobacco leaf baking by using the heat pump technology is very suitable. Compared with the traditional energy, the high-temperature heat pump unit is used as a heat source, and the heat supply and the required temperature rise temperature can still meet the requirement under the condition that other auxiliary heat sources are not added. The high-temperature heat pump unit can adopt a frequency conversion technology and is controlled by a microcomputer, so that the heat pump unit can provide heat and increase the temperature more sensitively and accurately.
The existing bulk curing barn adopts a dehumidification mode of strong dehumidification, and not only can the water vapor in the tobacco containing chamber be discharged in the process of strong dehumidification, but also the heat carried by the water vapor is discharged outdoors. According to research, the lost heat is about 10-20% of the total energy consumption in the process of forced moisture removal, and even reaches 25% at most, and moreover, the tobacco aroma emitted by the tobacco leaves is also removed in the moisture removal process of tobacco leaf baking. In terms of control technology and baking process, although semi-automation and automation of the existing bulk curing barn are basically realized, manual experience is still relied on for control in the process of temperature stabilization, temperature rise speed, humidity elimination time, coal addition amount and the like of baking, and the whole structure of the baking system and the baking process of the existing bulk curing barn are established on a dehumidification mode of coal-fired heat supply and strong humidity elimination, and research personnel are insufficient in the aspect of control because of the hysteresis and uncontrollable property of coal-fired temperature rise, and the research with progressiveness only achieves certain achievements in the aspects of automatic coal addition and automatic humidity elimination, but is still laggard in the aspects of intelligent control, intelligent baking and clustered baking. Therefore, the baking system of the bulk curing barn, which uses clean energy for heat supply, internal circulation for dehumidification and intelligent baking, is necessary.
