Description
Technical Field
The invention relates to the technical field of flue-cured tobacco and combustion furnaces, in particular to intelligent high-temperature high-efficiency energy-saving double-furnace double-combustion flue-cured tobacco equipment and process by utilizing biomass fuels such as agricultural and forestry wastes.
Background
Tobacco is one of important economic crops in China, and tobacco planting and product development play an important role in national economy and social production development. The tobacco planting area and the yield of China are the first place in the world, and Yunnan, Henan, Shandong, Gansu, Guizhou, Hunan and other provinces are planted, so that the tobacco planting method is an important tobacco production place in China. Wherein, the tobacco in Yunnan, Guizhou, Henan and Hunan provinces has the largest planting area and the highest yield, and accounts for about 60 percent of the whole country. The development of the tobacco industry provides an important foundation for promoting the development of the economic society, but a great amount of resources and energy are consumed by the planting and industrial production of a great amount of tobacco, and the environmental pollution pressure is increased sharply. On the other hand, in the production of tobacco and grain crops, a large amount of agricultural wastes such as straws, tobacco stalks and the like are also generated. According to incomplete statistics, the agricultural and forestry wastes generated in China each year are up to 16 hundred million tons, more than 50% of the agricultural and forestry wastes are not effectively utilized, and a large amount of biomass resources are wasted, so that the problems of straw burning and the like become important problems for restricting the low-carbon economy, the ecological environment and the social sustainable development.
As a key link of tobacco production, a tobacco leaf baking mode and a tobacco leaf baking process are important factors for determining the quality and the production efficiency of tobacco leaves. In China, the traditional tobacco leaf baking mainly uses fossil energy-coal, and only small coal kilns for baking tobacco in a fire coal mode are used according to incomplete statistics, namely more than 400 and ten thousand seats. A large amount of intensive and scattered tobacco curing houses which lack environmental protection standards and equipment generate a large amount of carbon emission in the tobacco production and operation process, and the emission of pollutants exceeds the standard, so that the atmosphere and the environment are seriously polluted. The traditional tobacco curing house has high energy consumption and low production heat efficiency, and in addition, in recent years, the coal price is increased, the production cost of tobacco leaves is obviously improved, and tobacco growers are generally difficult to bear. Particularly, in recent years, China vigorously implements 'low-carbon and environment-friendly' type economic and social development strategies, and the traditional fire coal type flue-cured tobacco mode cannot meet the requirements of economic and social sustainable development. The state has already made clear that the 'small coal kiln' which does not conform to the environmental protection regulations is firmly banned. Therefore, the development of novel low-carbon, environment-friendly and green tobacco leaf baking modes and processes becomes an urgent need for sustainable development of tobacco production.
Besides the tobacco leaf baking mode in the form of coal burning, if electric power is adopted as a baking heat supply source, the production cost is relatively high, and if extreme conditions such as power failure and the like occur, a large amount of tobacco leaves in a room can be rotten, so that the quality of the tobacco leaves is greatly influenced. After the flue-cured tobacco is advocated and required to be "forbidden to use coal" in China, the biomass combustion is generally adopted as a heat source to bake the tobacco leaves at present, most of equipment is of a separated type, the heat value of combustion heat supply is low, and the heat energy storage of the biomass is not fully utilized. Meanwhile, in order to meet the requirement of sustainable production of tobacco leaves, a large amount of stable biomass fuel supply sources are often needed, the processing cost of biomass is relatively high, the market price of common biomass particles is 1100-1200 yuan/ton, the production cost is greatly increased, the labor amount is remarkably increased, and the tobacco growers are often difficult to accept.
In order to further improve the existing biomass heat supply mode, some researchers improve and optimize equipment, although certain improvements are made on the aspects of fuel utilization rate, partial devices and the like, the limitations of the traditional biomass combustion heat supply equipment are still not broken through, and obvious defects exist in the aspects of raw material type selection, fuel heat energy utilization rate, heat supply value, production efficiency, production cost and the like. Traditional biomass flue-cured tobacco needs to process biomass into biomass particles, and the production cost is obviously increased.
Especially in the aspect of tobacco curing equipment and process, the traditional tobacco curing equipment and process which take fire coal or biomass particles as raw material sources mostly adopt horizontal type one-time combustion, the fuel combustion heat energy utilization rate is low, the coking rate is high, the combustion pollutant emission is high, the energy consumption is high, the environment is not protected, and the whole operation efficiency and the stability of the equipment are poor.
Therefore, aiming at key links and production reality problems of flue-cured tobacco production, the invention adopts biomass as the raw material through independent innovation in the aspects of equipment design, structure, process, implementation mode and the like, has various raw material sources, carries out tobacco leaf baking production and greatly reduces the production cost of the raw material. The innovative design adopts a double-furnace double-combustion integrated structure, greatly improves the utilization efficiency of the heat generated by burning the raw materials, has high heat value, does not discharge smoke during combustion, and is low-carbon, efficient, energy-saving and environment-friendly. By intelligent design, full automation can be realized in aspects of point/fire extinguishing, temperature change control and the like according to the production requirements of flue-cured tobacco, the requirements of sustainable production of tobacco leaves are completely met, and the tobacco leaf baking quality is obviously improved.
The equipment and the innovative process greatly improve the heat energy utilization rate of the biomass raw material, the unit energy consumption and the production cost are greatly reduced, the production efficiency is remarkably improved, the low carbon, environmental protection, high efficiency and energy conservation are realized, the technical problem of the traditional biomass flue-cured tobacco is broken through, the low carbon, environmental protection and green flue-cured tobacco is realized, a new path is opened for improving the income of tobacco growers and the green flue-cured tobacco, the problems of recycling, high efficiency and comprehensive utilization of the waste biomass in agriculture and forestry are solved, the low carbon, energy conservation and environmental protection sustainable development of tobacco production are promoted, and the equipment and the innovative process have important practical significance.
