Ash fertilizer firing device

Abstract

The invention discloses an ash fertilizer firing device which can effectively carry out firing on wheat straw in a concentrating mode, a firing process is stable and efficient, full firing can be guaranteed, prepared ash fertilizer is high in purity, generated smoke can be effectively processed, and smoke pollution can be avoided. The ash fertilizer firing device comprises an incineration kiln, a feeding device and a smoke purifying device. An incineration inner cavity is arranged at the incineration kiln. The incineration kiln is oblique, and the angle between the incineration kiln and the horizontal plane is 10-60 degrees. A transmission shaft driven by a main motor is arranged in the incineration inner cavity. A plurality of material dispersing bodies for stirring materials are arranged on the transmission main shaft. An air inlet, a smoke outlet, a feeding opening and a material clearing opening-closing door are arranged on the incineration kiln. The ash fertilizer firing device has the advantages that separating effect is good, removing of solid particles and dust in smoke can be achieved, raw materials are subjected to drying through smoke waste heat, following firing effect is improved, a preheating structure is arranged, and following incineration can be well and fully guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of fertilizer production, in particular to a burning device for ash fertilizer. 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 abundant element,...
