A plant ash production and collection device

Abstract

The invention discloses a plant ash production and collection device, which can effectively perform centralized incineration treatment of wheat straws, treat generated flue gas and avoid smoke dust pollution, the incineration process is stable, efficient and completed, and the finished ash fertilizer has high purity. The device comprises an incineration kiln, a feeding device and a smoke purification device, wherein the incineration kiln is provided with an incineration inner chamber, and is inclined and forms an angle of 10-60 degrees with the horizontal plane; the incineration inner chamber is internally equipped with a transmission main shaft driven by a main motor; the transmission main shaft is equipped with a plenty of material spreading bodies used for stirring materials; and the incineration kiln is equipped with an air inlet, a smoke outlet part, a feeding port and a material cleaning start-stop door. The inventive device has good separation effect, can realize removal of solid particulates and dust in the flue gas, and dry raw materials by the use of flue gas waste heat so as to improve the subsequent incineration effect, and has a preheating structure which can well and fully ensure subsequent incineration.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a plant ash production and collection device. Background technique [0002] At present, there are often many plants that are difficult to handle and have little use value, such as weeds in the garden, dead wood, broken branches of plants, crop straw, etc. Among them, the generation of wheat straw in our country every year The amount is quite large. If wheat straw or other plants are directly used as fertilizers for landfill, due to their relatively large size, slow decomposition, and poor actual fertilizer supply capacity, it is easy to cause many negative effects. Therefore, it can be selected to be incinerated centrally, so as to be burned into plant ash fertilizer for rational use. Plant ash is the ashes of various plants after burning, so almost all the mineral elements contained in plants are contained in plant ash. Among them, potassium is the m...

Problems solved by technology

However, at present, in the process of burning fertilizer, there are several main shortcomings: it is easy to produce a large amount of solid particles, thereby forming smoke and dust, which has adverse effects on the surrounding environment; because of centralized burning, it is easy to appear insufficient burning process , the utilization rate of raw materials is limited and the content of impurities will be too high; and because there are many impurities and residual materials in the plant ash fertilizer made, follow-up treatment is required, which increases the process and has a negative impact on production efficiency and cost
