Abstract

The invention relates to a solar energy storage and heat supply tobacco leaf curing system which comprises the following modules: a high-temperature energy storage and heat supply module comprises an air supply mechanism, an energy storage mechanism, a valley electricity heating mechanism, an air inlet and an air outlet, the energy storage mechanism is electrically connected with an external power supply and can charge and release heat, and the air supply mechanism and the valley electricity heating mechanism are electrically connected with the external power supply; fresh air can be supplemented through the air inlet and is sent into the curing barn through the air outlet after being heated; the solar heat supply module is communicated with the heating mechanism of the high-temperature energy storage heat supply module to supply energy; the heat pump mechanism communicates with the heating mechanism of the high-temperature energy storage heat supply module and can supply energy; the low-temperature energy storage heat supply module can receive energy supplied by the solar heat supply module and can supply energy to the heating mechanism in cooperation with the heat pump mechanism; and the environment heat and / or curing barn preheating collection module is communicated with the low-temperature energy storage and heat supply module and can provide functions for the low-temperature energy storage and heat supply module. According to the invention, all-weather efficient collection of solar energy and storage of solar energy and off-peak electricity can be realized.

Description

technical field [0001] The invention relates to a curing system and a control method, in particular to a tobacco leaf curing system and a control method for heating with solar energy storage. Background technique [0002] At present, my country's tobacco leaf curing technical specification adopts the technical specification (trial version) of intensive curing room on March 15, 2010 (including corrections and supplements), with coal as the main fuel source, and every 5,000 kilograms of tobacco leaves (dried tobacco leaves 500 kg) needs to consume about 1,500 kg of coal, which has problems such as large pollution, easy pollution of tobacco leaves by exhaust smoke, large heat loss, and low thermal efficiency. Energy costs are 2-3 times higher than coal-fired heating methods, so how to use solar energy and low-peak electricity to achieve zero-emission and low-cost heating and curing of tobacco leaves is an urgent problem to be solved, and the key technology to solve this problem I...

Problems solved by technology

The modular design of the energy storage in the baking system is suitable for standardized and industrialized production, and it is easy to install and maintain; the phase change latent heat of nanocomposites is used to directly convert solar energy into thermal energy and store it in the heat storage equipment, which solves the problem of new energy solar energy in baking. The energy flow density in housing applications is low, affected by natural conditions such as day and night, seasons, weather, geographical latitude and altitude, the solar radiation is intermittent and extremely unstable, the efficiency of solar energy utilization is low, and the energy conversion loss is large. The energy storage system realizes the storage of solar energy and stable heating use
