Solar straw reaction furnace

The invention provides a solar straw reaction furnace. The solar straw reaction furnace comprises a straw crushing container, wherein the lower side of the straw crushing container is connected with a heating container with a heat preservation wall on the outer surface through a connection neck, the volume of the heating container is greatly smaller than that of the straw crushing container, and a first electronically controlled gate is arranged in the connection neck; the lower end of the heating container is provided with a second electrically controlled gate; an electronic pressure gate is further arranged in the heating container, and is coupled to controllers of the first and the second electrically controlled gate; the lower side of the heating container is provided with a puffing straw box; the reacting furnace further comprises a heat-collecting slope composed of parallel vacuum heat-collecting tubes; the vacuum heat-collecting tubes on the heat-collecting slope are communicated with a heat conducting copper tube wound on the inner wall of the heating container, and heat conducting oil is sealed in each of the vacuum heat-collecting tube and the heat conducting copper tube; the reacting furnace further comprises a water tank for providing moisture for the straw crushing container through a pipeline. According to the reacting surface, solar can be utilized to perform puffing treatment on the straw in the furnace so that the combustion value of the straw can be sufficiently increased.
