Abstract

The invention provides a slot type solar energy collection device based on a black body absorption principle. A rotary table fixedly-connected gear is installed on the lower portion of a heat collection device rotary table of the device, a paraboloid heat collection tube joint shaft drives two heat collection tube supporting columns and a parabolic reflector to rotate axially, a heat collection tube is installed on the two heat collection tube supporting columns, a water pump is communicated with the heat collection tube through two flexible water tubes to form a water circulation passage, a gap is formed in the side face of the heat collection tube which is of a double circular tube sleeve cavity structure, and an interlayer of a double circular tube is filled with a nanofluid medium; a photoelectric sensor and a temperature sensor transmit a sensed signal to a control integrated box. The problems that for an existing slot type solar energy collection heat collection technology, the heat collection tube heat collection efficiency is low, the heat transmission efficiency is low, and the heat loss is large are solved. Accordingly, the collection efficiency and transmission efficiency are improved, and by means of an aerogel insulating layer, heat loss due to radiation is reduced; by means of a light chasing system and a temperature control system, the whole adaptability of the device is improved.

Description

technical field [0001] The invention relates to a trough-type solar energy collection device, in particular to a trough-type solar energy collection device based on the principle of blackbody absorption, and belongs to the field of solar thermal power generation. Background technique [0002] For nearly 200 years, fossil energy has supported the progress of human civilization and social and economic development. However, due to the huge consumption of human beings and their non-renewability, fossil energy is gradually becoming exhausted. Therefore, new energy has become the new favorite of the times. [0003] There are mainly two types of solar energy utilization methods: photoelectricity and photothermal utilization. Among them, the photoelectric utilization method has high power generation quality, but the efficiency is low, only 20%-30%, and the cost is high. The device is unstable compared with the photothermal utilization method. extremely serious. Photothermal power ...
