Solar energy and fuel mixed heating heat collector

Abstract

The invention relates to the technical field of new energy utilization, in particular to a solar energy and fuel mixed heating heat collector. The heat collector can realize solar power generation when sunlight meets the power generation conditions, and uses a gas power generation device when no sunlight can be used. The heat collector comprises a base plate; a heat collector shell covers the baseplate; an internal heat regenerator outer shell, a cold air channel, a hot exhaust channel, an internal heat exchanger and a heat collector inner sleeve are arranged in the heat collector shell in sequence in a sleeved mode; a heat regenerator and a cylinder are arranged at the upper part of the base plate in a heat collector inner sleeve; a heat collecting device is arranged at the upper part ofthe heat collector shell; the bottom of the heat collecting device is sealed; the bottom of the heat collecting device and the upper part of the heat collector inner sleeve form a combustion chamber;a finned heating pipe is arranged in the heat collector inner sleeve; one end of the finned heating pipe is connected with a cold end of the cylinder, and the other end is connected with a hot end ofthe cylinder; and the bottom of the base plate is connected with a Stirling engine shell through a cylinder base.

Description

technical field [0001] The invention relates to the technical field of new energy utilization, in particular to a solar and fuel mixed heating heat collector. Background technique [0002] With the rapid development of my country's economy, the pressure of environmental problems is becoming more and more serious. The use of clean energy has received great attention from the state, solar power generation technology has developed rapidly, and the maturity of technology has continued to increase. Solar power generation technology has formed butterfly solar Stirling power generation technology, tower solar power generation technology and trough solar power generation technology. Solar energy provides inexhaustible clean energy, but there are also some objective constraints, such as: the absence of the sun at night and the influence of weather changes make it impossible to continuously generate electricity, resulting in unfavorable factors such as shocks to the grid, which direc...

Solar energy provides inexhaustible clean energy, but there are also some objective constraints, such as: the absence of the sun at night and the influence of weather changes make it impossible to continuously generate electricity, resulting in unfavorable factors such as shocks to the grid, which directly affect solar power generation technological development

[0003] The Stirling engine is a small, high-efficiency heat engine, which can achieve a power generation efficiency of up to 30% when used in a dish solar power generation system; it can also use gas as energy to generate electricity, but due to the particularity of the Stirling engine , the collector heating devices used in the dish solar power generation system and the gas power generation system are completely different, so the Stirling machines for these two purposes cannot be used universally
