Description

Circulation condensed roasting room baking system in clean energy
Technical field
It is especially a kind of for heat source and to use internal air circulation using clean energy resource the invention belongs to tobacco leaf baking system Tobacco leaf baking system.
Background technology
At present, domestic tobacco leaf baking system is in heat supply, and the ratio that fire coal occupies is very big, and in Tobacco Leaf Curing In, often toasting the dry cigarettes of 1kg needs to disappear coal consumption for about 1.5 ~ 2.0kg, and often discharges the required theoretical heat dissipation of 1kg moisture Amount is about 2559.5 ~ 2580.3kJ, and the water content of China various regions fresh tobacco leaf is mostly 80 ~ 90%, with the low base position calorific capacity of coal 20809kJ/kg is calculated, and the theoretical coal consumption per 1kg dry tobacco leafs is only 0.423 ~ 0.952kg, therefore every in Tobacco Leaf Curing 2.778 ~ 4.505 times that the practical coal consumption needed for 1kg moisture is theoretical value are discharged, the barn thermal efficiency is only 22.2% ~ 36.0% Between, ineffective energy consumption is very high.Moreover, since the burning of fossil fuel is insufficient and the steady temperature of hysteresis quality, liter is uneven and shadow The quality of cured tobacco leaf is rung, ineffective energy consumption is excessively high to lead to waste of fuel, discharges a large amount of SO2、CO2、NO2With the pollutions such as particulate matter Object causes environmental pollution various problems, therefore studies in China personnel have begun to explore biomass energy, solar energy, air source heat pump The research in terms of bulk curing barn heat supply such as unit.
There is wide national territorial area in China, possesses abundant solar energy resources, about in 3348 ~ 8371MJ/(m2·a)Between, The whole nation is averagely about 5860MJ/(m2∙a).Since 21 century, low-grade utility technology has been achieved for very big in solar energy Progress is current using most universal, the highest solar utilization technique of degree of commercialization, and China is in solar energy low-temperature thermal profit With technically very ripe.At present, China is the country of solar thermal collector yield and sales volume maximum in the world, so Carrying out heat supply using solar energy in the intensive baking room of the more rich cigarette district of solar energy resources has good application foundation.Heat pump Be a kind of refrigeration system, release heat heat supply condensed by condenser inner refrigerant, is a kind of efficient energy-saving device, technology into Ripe, dependable performance is used widely, and wherein air source heat pump is most economical, convenient in heat pump techniques, and tobacco flue-curing Work progress generally at the beginning of summer and autumn, ambient temperature is higher at this time, when being in heat pump Energy Efficiency Ratio highest, so utilizing Heat pump techniques baking tobacco leaves are particularly suitable for.Relative to traditional energy, using high temperature heat pump unit as heat source, do not increasing other In the case of auxiliary thermal source, institute's heating load and required warming temperature still can meet demands.Frequency conversion can be used in high temperature heat pump unit Technology and using micro computer control sensitiveer, accurate offer heat and can promote temperature.
Existing bulk curing barn not only exhausts the water in cigarette-filling house using the wet dehumidification mode of forced-ventilated during forced-ventilated is wet Heat entrained by vapor is still discharged outdoor by steam.It is found by researches that during forced-ventilated is wet, the heat that loses Amount is about the 10% ~ 20% of total energy consumption, and highest is even up to 25%, moreover, is also exhausted during the hydrofuge of tobacco flue-curing The cigarette perfume that tobacco leaf comes out.In control technology and baking process, although existing bulk curing barn has realized half certainly substantially Dynamicization and automation, but surely warm duration, heating rate, hydrofuge opportunity, coal opportunity, coal amount etc. are still gone back in baking process It relies on artificial experience to go to control, and overall structure due to existing bulk curing barn baking system and baking process are all to establish On the wet dehumidification mode of coal heating, forced-ventilated, and because the hysteresis quality and uncontrollability of coal-fired heating cause researcher couple Insufficient in the research of control aspect, the research for comparing having progressed property is also only achieving one in terms of automatic stoking, automatic hydrofuge A little achievements, and it is still relatively backward in terms of intelligent control, intelligence baking, clustering baking.Cleaning is used because the invention is a kind of Energy heat supply, interior circulating dehumidification, the bulk curing barn baking system of intelligence baking is very necessary.
