Hot-water centralized heating tobacco flue-curing device adopting combination of solar energy and biomass fuels

Abstract

The invention relates to a hot-water centralized heating tobacco flue-curing device adopting the combination of solar energy and biomass fuels. The hot-water centralized heating tobacco flue-curing device of the invention comprises a hothouse, upon the roof of which is arranged solar water heaters and inside a heating chamber of which are arranged a radiator and a blower fan. The radiator and theblower fan are corresponding to a tobacco-filling chamber of the hothouse; a solar energy water inlet manifold communicates with a drainage pipe of the radiator; the solar energy water inlet manifoldcommunicates with every solar water heater; a solar energy outfall sewer communicates with a reservoir communicating with a boiler inlet pipe; a third pipeline communicates with a boiler outlet pipe and a radiator inlet pipe also communicates with the boiler outlet pipe; and the radiator outlet pipe communicates with the boiler inlet pipe. The hot-water centralized heating tobacco flue-curing device of the invention heats water via the combination of solar energy and biomass fuels, and enables hot water to flow in the radiator pipeline of the heating chamber of the hothouse; the radiator emits heat which flows within the tobacco-filling chamber and the heating chamber of the hothouse driven by the blower fan, thus to bake the tobacco inside the tobacco-filling chamber and realize tobacco-baking purpose. The hot-water centralized heating tobacco flue-curing device can save energy and reduce pollution and emissions.

Description

Technical field: [0001] The invention belongs to the field of tobacco curing equipment, and in particular relates to a hot water centralized heating tobacco curing equipment combined with solar energy and biomass fuel. Background technique: [0002] After the Copenhagen World Environment Conference, countries around the world are increasingly emphasizing energy conservation, emission reduction, and sustainable economic development. my country is a big flue-cured tobacco production country. With the adjustment of modern agricultural planting structure and the improvement of scale, large-scale intensive curing barns are gradually promoted in production. Generally, the intensive curing barns currently used are equipped with small computer automatic control equipment. China produces 2.3 million tons of tobacco leaves. Coal is basically used for direct heating of cured tobacco leaves. According to rough estimates, about 3.5 million tons of coal is consumed every year, and more ...

Problems solved by technology

[0003]Many scholars have devoted themselves to the research and exploration of the heating method of flue-cured tobacco baking. 1) Solar energy is a clean and clean energy source. Generally, there is little rain in the tobacco leaf baking season. There are abundant solar energy resources, and there have been a number of achievements on solar energy utilization, but the formed products cannot accurately control the use of solar energy during baking (patent number ZL: 00920064695.4; 200920253731.1; 201020133448.8; The design of the house does not meet the problem of conflicts with large-scale planting (patent number ZL: 97204110.9, 200920111953.X), so the development and utilization of solar energy plays an auxiliary role in baking applications, and large-scale promotion is limited; The baking equipment in terms of material fuel, the patent (Patent No. ZL: 200420075191.X) uses the gas generated by the degradation of biomass to burn for heating, and the gas generated by the degradation of biomass is greatly affected by the temperature

Most of the tobacco growing areas in my country are in mountainous and hilly areas, and the temperature is lower than that in plain areas. It is difficult to meet the baking requirements especially in the case of low temperature in the later stage of baking; the patent (patent number ZL: 200720037803.X; Material fuel briquette flue-cured tobacco, but biomass fuel has lower heat generation than coal, and the frequency of adding fuel to tobacco farmers in operation is increased, so that the workload of tobacco farmers is increased. It has been in the tentative test stage, and in production no large-scale promotion

3) The patent (Patent No. ZL: 200120109694.3) has been tried on the hot water circulation baking equipment, but the hot water circulation heater is arranged in the traditional furnace, and the utilization rate of the energy released by the combustion of the fuel is greatly reduced. In addition, this kind of roasting The housing structure is relatively backward in my country, and it is basically eliminated in the production of flue-cured tobacco
