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

Abstract

The invention discloses an incinerator for crop straws, and aims to provide an incinerator capable of effectively and intensively burning wheat straws, effectively treating flue gas and preventing smoke contamination caused by flue gas pollution, wherein a stable and efficient burning process can be ensured, the sufficient burning can be guaranteed and the purity of an ash fertilizer is high. The incinerator comprises an incineration kiln, a feeding device and a smoke purifying device, wherein the incineration kiln comprises an inner incineration cavity, the incineration kiln is inclined, an angle of 10-60 degrees is formed between the horizontal plane and the incineration kin, and the inner incineration kiln is provided with a driving spindle driven by a main motor; the driving main motor is provided with a plurality of material scattering bodies used for poking materials, and the incineration kiln is provided with an air inlet, a smoke outlet, a feeding hole and a purging opening and closing door. The incinerator provided by the invention has the beneficial effects of good separation effect, and solid particulate matters and powder in flue gas can be cleaned up; furthermore, raw materials can be dried by the waste heat of the flue gas, therefore the successive burning effect can be improved; in addition, the incinerator is provided with a preheating structure, and the subsequent incineration can be ensured more sufficiently.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to an incineration device for crop stalks. 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 most ab...
