Description

Technical Field

[0001] The utility model relates to the technology of agricultural equipment, in particular to an integrated device for straw gasification, grain drying and electric heat co-generation. Background Art

[0002] Straw recycling refers to the process of effectively recycling and utilizing the straw remaining after crop harvesting. As a by-product of crop production, straw is produced in huge quantities every year. Traditionally, it is often regarded as waste. However, in fact, through scientific treatment and utilization, straw can be transformed into various valuable resources.

[0003] When the existing straw recycling devices are in use, generally, the straw is directly burned, which will bring pollution problems. Another method is to ferment the straw. Although the fermentation of straw can produce combustible gas for utilization, a fermentation tank needs to be built. When used on a household basis, the problems of storage and leakage of combustible gas cannot be avoided, and it requires specialized professionals to supervise and guide the use, wasting a lot of manpower. When the grain is harvested, there is a large amount of moisture, and it needs to be dried or sun-dried before it can be stored for a long time. Straw recycling and grain sun-drying are at the same time node, and taking both into account will waste a lot of manpower and time. Content of the Utility Model
