Gas-intensive complete equipment for baking tobaccos by biomass charcoal

Abstract

Disclosed is gas-intensive complete equipment for baking tobaccos by biomass charcoal. The gas-intensive complete equipment is provided with a plurality of carbonization furnaces special for biomass flue-cured tobaccos. A discharge outlet of a drying machine is connected with feed inlets of the carbonization furnaces. A honeycomb burner is arranged on each carbonization furnace, smoke generated bymaterial carbonization of the carbonization furnaces enters primary and secondary oil-gas separators through smoke pipelines, gas outlets of the oil-gas separators are connected with a tubular condenser, the output end of the tubular condenser is connected with a gas storage tank, a part of fuel gas in the gas storage tank is delivered to a combustor, and flames generated after combustion enter ahot blast heater special for an intensive baking room to bake tobacco leaves; another part of the fuel gas is delivered to a direct-fired hot blast heater to provide a heat source for heating materials to the drying machine. The gas-intensive complete equipment has the advantages that the combustion energy density of the carbonized fuel gas is remarkably increased through processes such as special purification, and continuous and stable hot air is guaranteed in the tobacco baking process; the production cost is remarkably reduced, and benefits are remarkably improved.

Description

technical field [0001] The invention relates to a complete set of flue-cured tobacco equipment, in particular to a complete set of biomass charcoal and gas-intensive flue-cured tobacco equipment. Background technique [0002] my country produces a large amount of agricultural and forestry waste biomass such as straws, shells, cores, and branches every year. However, due to the lack of simple and effective comprehensive treatment equipment and measures, these huge agricultural and forestry wastes are mostly "burned" or "thrown into the wilderness". , not only caused a serious waste of resources, but also produced serious environmental pollution. The recycling, environmental protection, and efficient utilization of agricultural and forestry waste biomass have always been severe challenges and important issues for the sustainable development of agriculture and the environment in my country. [0003] Tobacco is one of the most important economic crops in my country, with the pla...

Problems solved by technology

Traditional tobacco leaf curing is mostly coal-fired. According to incomplete statistics, there are more than 4 million coal-fired flue-cured rooms. These flue-cured rooms have high energy consumption, low thermal efficiency of the system, and generate a large amount of carbon emissions during the production process. It has caused serious air pollution, and the price of coal has risen in recent years, directly increasing the cost of tobacco leaf production. Small coal kilns that do not meet environmental protection regulations have been completely banned by the state.

Electricity is used as the heating source, and the production cost is relatively high. Especially in case of special circumstances, stopping the electrode during high-temperature baking will easily cause a large amount of tobacco leaves to rot, which greatly affects the quality of tobacco leaves.

However, when biomass is used as a heat source, the power consumption in the process of processing and production is large, and the production cost is high, which is often difficult for tobacco farmers to accept. Especially in the process of processing, it is very easy to produce coking problems, which is difficult to be effectively treated, and the equipment cannot Continuous and stable operation, resulting in increased production costs and reduced production efficiency
