Description

Technical Field

[0001] The utility model relates to the technical field of combustion recovery, in particular to a device for recovering ash after straw combustion. Background Art

[0002] After burning straw, wood ash is often left behind. Wood ash is an insoluble substance. Since wood ash is rich in mineral elements, it can be made into fertilizer. Wood ash is light and alkaline. It is easily blown away by the wind when dry and by water when wet. Contact with nitrogen fertilizers can easily cause volatilization loss of nitrogen.

[0003] In the prior art, when the ash after burning the straw is taken out from the combustion furnace, the ash will fly due to air flow and other reasons, making it difficult to recover and having a poor collection efficiency. The ash will diffuse into the air, causing environmental pollution. At the same time, when the ash is recovered, the ash is piled up on a placement plate at one time, and then the ash is humidified, so that the moisture contacted by the outer ash and the inner ash is inconsistent. Adding too much water will affect the recovery and utilization of the ash. If too little water is added, the inside of the accumulated ash will not be in contact with water, and it is easy to be blown away during recycling.

[0004] Therefore, we propose a plant ash recovery device after straw combustion to solve the above problems. Utility Model Content
