An inorganic agricultural fertilizer production device

Abstract

The invention discloses an inorganic agricultural fertilizer production device, and aims to provide a method that can effectively carry out centralized burning treatment of wheat straw, the burning process is stable and efficient, can ensure sufficient burning, the ash fertilizer produced is high in purity, and can The flue gas can be effectively treated to avoid the device that causes smoke and dust pollution. It includes an incineration kiln, a feeding device, and a smoke cleaning device: the incineration kiln has an incineration inner cavity, the incineration kiln is inclined and is 10 to 60 degrees from the horizontal plane, and the incineration inner cavity is provided with a main A drive spindle driven by a motor, the drive spindle is provided with a plurality of bulk material bodies for dislodging the material, and the incineration kiln is provided with an air inlet, a smoke outlet, a feeding port, and a material cleaning opening and closing Door. The beneficial effects of the invention are as follows: the separation effect is excellent; the solid particles and dust in the flue gas can be removed; the waste heat of the flue gas is used to dry the raw materials, and the subsequent firing effect is improved; Adequate assurance of subsequent incineration.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, in particular to an inorganic agricultural fertilizer production 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 mos...

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
