technical field

The utility model belongs to the technical field of solar photothermal power generation, in particular to a solar photothermal power generation heat collection system with tracking function.

Background technique

Solar thermal power generation refers to the use of large-scale arrays of parabolic or dish-shaped mirrors to collect solar heat, provide steam through heat exchange devices, and combine traditional turbogenerator technology to achieve the purpose of power generation. The use of solar thermal power generation technology avoids the expensive silicon crystal photoelectric conversion process, which can greatly reduce the cost of solar power generation. Moreover, this form of solar energy utilization has an incomparable advantage over other forms of solar energy conversion, that is, the water heated by solar energy can be stored in huge containers, and it can still drive steam turbines to generate electricity a few hours after the sun goes down. . Therefore, solar thermal power generation has been increasingly favored by people.

The core of the solar thermal power generation system is the solar thermal heat collection and heat exchange device, which is responsible for collecting and utilizing the solar thermal part, and the collected heat is used to generate steam, which is supplied to the subsequent steam turbine for power generation. The above-mentioned heat collecting and exchanging device can be used in combination with the energy storage device to transform the existing coal-fired and gas-fired generating sets. Existing heat collection and heat exchange devices generally include three types: trough type, tower type and disc type, among which the trough type has the widest application range. Existing trough-type photothermal heat collection and heat exchange devices generally include a parabolic reflector and a heat collecting tube located in the center. In order to collect the light and heat in solar energy to the maximum extent, it is necessary to configure an automatic tracking device to align the parabolic reflector at all times. the position of the sun. The existing automatic tracking device often has a complex structure; and there is only one heat collecting tube on the support of the heat collecting system, so the heat collection efficiency needs to be improved.
