A centralized plant ash fertilizer production equipment

Abstract

The invention discloses a plant ash fertilizer centralized production equipment, aiming to provide a kind of equipment which can effectively carry out concentrated burning treatment on wheat straw, the burning process is stable and efficient, can ensure sufficient burning, the ash fertilizer produced has high purity, and can reduce the production of wheat straw. The flue gas is effectively treated to avoid the equipment that causes smoke pollution. It includes an incineration kiln, a feeding device, and a smoke-cleaning device: the incineration kiln has an incineration cavity, the incineration kiln is inclined and is 10 to 60 degrees from the horizontal plane, and the incineration cavity is equipped with a main The transmission shaft driven by the motor, the transmission shaft is provided with a plurality of bulk materials for moving materials, and the incineration kiln is provided with an air inlet, a smoke outlet, a material inlet, and a material cleaning opening and closing Door. The beneficial effects of the invention are: excellent separation effect; removal of solid particles and dust in flue gas; use of waste heat of flue gas to dry raw materials to improve subsequent firing effect; with preheating structure, better and more Fully guarantee the subsequent incineration.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a plant ash fertilizer centralized production equipment. 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, potassi...

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
