Ash slag treatment device for biomass heat supply system and treatment method of ash slag treatment device

Abstract

The invention discloses an ash treatment device for a biomass heat supply system, the ash treatment device comprises a crushing box and a reaction box, the crushing box is fixedly mounted on the reaction box, the crushing box and the reaction box are fixedly communicated through a same material guide pipe, a feeding hopper is fixed at the top of the crushing box, a material guide mechanism and a crushing mechanism are arranged in the crushing box, and the feeding hopper is fixed at the bottom of the crushing box. A pushing mechanism is fixed to the bottom of the smashing box and located in the material guiding pipe, a cam is fixed to the rightmost end of the pushing mechanism, a material pressing mechanism is arranged below the cam, a material guiding table is fixed to the right side in the reaction box, and a material pushing mechanism is rotationally inserted between the material guiding table and the interior of the left side of the reaction box. One end of the pushing mechanism is in transmission connection with a stirring mechanism through a transmission mechanism. According to the invention, ash and an acidic reaction solution are promoted to fully react, so that a porous structure is formed.

Description

technical field [0001] The invention relates to the technical field of ash treatment, in particular to an ash treatment device and a treatment method for a biomass heating system. Background technique [0002] With society's increasing demand for energy, fossil fuels as the main source of energy are rapidly declining. Therefore, looking for a renewable alternative energy source has become the focus of general attention in society. Biomass fuel heating in various renewable energy sources has been widely used because of its less environmental pollution. Usable biomass fuels mainly include various agricultural wastes such as rice husks, cotton stalks, rice stalks, rape stalks, and corn stalks, as well as forestry wastes such as twig firewood, wood scraps, and tree roots. The common points of these biomass fuels are: 1. The volatile content of the combustible base is very high, mostly above 80%; Especially when agricultural waste is used as fuel, slagging and ash blocking are ...

AI Technical Summary

Problems solved by technology

[0003] Among them, biomass will produce a lot of ash after being processed in the combustion system. The inorganic substances contained in the ash can be recycled again to form solid waste. It is necessary to react the ash with an acidic solution to make the surface of the ash block porous, making the Ash slag can absorb more liquid fertilizer in the follow-up work. There are some deficiencies in the existing ash slag processing process. For example, some ash slag blocks are too large, which may cause insufficient reaction and cannot meet production needs.
