Embodiment

[0059] The flue-cured tobacco area takes Kunming City, Yunnan Province as an example. It is located at 25° north latitude and 103° east longitude. The local flue-cured tobacco months are from July to September. see image 3 , every 10 dense barns are connected as a whole, a total of 60 seats in 2 rows and 3 columns, and the total roof area is about 3000m2 2 . The smoke loading capacity of a single barn is 4000kg.

[0060] Preliminary design of solar thermal heating module:

[0061] In line with the principle of solar thermal heating priority, the preliminary calculation of solar collectors is carried out first. According to experience and estimates, the temperature of water heated by solar collectors can reach up to 90°C, and water at 90°C can heat air at 20°C to a maximum of about 50°C, so solar collectors can only provide heat alone in the early stage of tobacco leaves. . Therefore, the design standard of the solar collector is that in the case of sufficient light durin...

Abstract

The invention discloses a tobacco primary curing system with solar photo-thermal-photovoltaic-natural gas complementary energy supply. The tobacco primary curing system comprises a bulk curing barn module, a solar photo-thermal heating module, a solar photovoltaic heating module, a natural gas hot blast stove heating module and an intelligent control module. Based on the principle of preferentialheat supply of solar energy, heat required for tobacco primary curing is provided in a solar photo-thermal, photovoltaic and natural gas complementary energy supply mode, the three heating systems aremade to operate independently and coordinately through the intelligent control module, and energy conservation, emission reduction, accurate curing, labor saving and time saving are achieved.

Description

technical field [0001] The invention belongs to the field of energy utilization, and in particular relates to a tobacco leaf primary curing system with complementary energy supply from solar heat, photovoltaics and natural gas. Background technique [0002] my country is the country with the largest tobacco planting area in the world, and the output of flue-cured tobacco has ranked first in the world for many years. Intensive curing barns are special equipment for intensive roasting and processing of tobacco leaves. Most of the existing intensive barns are conjoined, forming dozens or even hundreds of conjoined intensive barns, and the roof area can reach up to 3000m 2 above. [0003] With the improvement of environmental protection requirements in our country, the primary curing system of tobacco leaves is gradually eliminating highly polluting biomass or coal-fired energy, and replacing it with clean and pollution-free electric energy, solar energy or natural gas. Electr...
