Abstract

A phase change heat storage type solar heater consists of a phase change heat storage heater, a solar heat collector and a bracket for supporting the phase change heat storage heater and the solar heat collector, wherein the phase change heat storage heater comprises a heat-preserving box, a heat-conducting pipe, a heat exchange coiled pipe and a phase change heat storage material. A system for producing biodiesel by utilizing solar energy comprises the phase change heat storage type solar heater, an oil storage container, biodiesel equipment, a circulating pump, a control device and a solar power supply. A method for producing the biodiesel by utilizing the solar energy comprises the step of reacting by using the system for producing the biodiesel by utilizing the solar energy under normal pressure and at the temperature of between 50 and 70 DEG C, wherein methanol is added according to the molar ratio of the methanol to a grease raw material of 6:1; and the adding amount of calcium oxide is 2 to 6 percent of the mass of the grease raw material.

Description

technical field [0001] The invention belongs to the field of solar energy utilization and biodiesel production, and in particular relates to a solar heater and a system and method for producing biodiesel by utilizing solar energy. Background technique [0002] Under the double impact of energy crisis and environmental problems, the development of new energy, especially green renewable energy, is of great significance. As the main source of all energy on the earth, solar energy is an endless, pollution-free, clean and green energy. No matter where on the earth there is solar energy, which can be developed and utilized locally, and there is no transportation problem, especially for rural areas, islands and remote areas with underdeveloped transportation. In addition, the development and utilization of solar energy will not produce waste residue, waste water, waste gas, and noise, and will not affect the ecological balance, cause pollution and public nuisance, so it will becom...
