Diameter-changing tube type air flow tobacco shred drying device based on groove type light gathering solar energy

Abstract

The invention discloses a diameter-changing tube type air flow tobacco shred drying device based on groove type light gathering solar energy. Sunlight is gathered to a vacuum metal-glass through pipe through an efficient reflecting collecting lens placed on a groove type heat collector support, heat conduction oil is extracted out of a storing and releasing hot oil tank through a circulating oil pump, a valve leading to a heat collector is opened, the heat conduction oil is conveyed into the vacuum metal-glass through pipe through a thermal insulation oil pipe to be heated to a preset temperature, energy of part of heat conduction oil is stored in a phase change material so as to cope with influence of unstable weather factors, another part of heat conduction oil is directly stored, the oil temperature is measured through a temperature sensor in the storing and releasing hot oil tank, a valve leading to a heat exchanger is opened, and the heat conduction oil enters the liquid-gas heat exchanger through a thermal insulation oil pipe to exchange heat with process gas; after heat exchange, the heat conduction oil is circulated into the storing and releasing hot oil tank, a boiler fan blows the heated process gas into a diameter-changing tube, tobacco shreds are dried, and the well dried tobacco shreds enter a cyclone separator along with air flow to be separated; the tobacco shreds fall into a tobacco shred placing box through the blanking airlock position at the bottom of the cyclone separator, and the process gas leaves the top of the cyclone separator and returns to the boiler fan installed at the low position to be circulated. A groove type light gathering system is adopted to supply energy, the tobacco shreds are dried through the diameter-changing type drying tube, energy can be saved, the environment is protected, the plant height requirements of the drying tube are effectively reduced, drying efficiency can be effectively improved, and the diameter-changing tube type air flow tobacco shred drying device has a wide application prospect in the field of solar energy heat utilization.

Description

technical field [0001] The design of the present invention relates to a variable-diameter tubular airflow drying device, in particular to a variable-diameter tubular airflow drying device based on trough-type concentrating solar energy, which belongs to the technical field of solar energy applications. Background technique [0002] Energy is an important material basis for economic and social development. Since the industrial revolution, the world's energy consumption has increased sharply, fossil energy resources such as coal, oil, and natural gas have been consumed rapidly, and the ecological environment has continued to deteriorate. In particular, greenhouse gas emissions have led to increasingly severe global climate change, and the sustainable development of human society has been seriously threatened. Generally, when cigarette factories dry tobacco, they often use combustion furnaces to supply energy. The combustion furnaces basically burn oil or natural gas, which not...

Problems solved by technology

Although solar energy is ubiquitous, the solar radiant energy flow density reaching the earth is low. To obtain solar radiant energy with a high energy flow density, heat energy at a higher temperature can be obtained by means of concentrating light to provide energy for industries.
