A gray residue treatment device and its treatment method for the biomass heating system

Abstract

The invention discloses an ash and slag processing device for a biomass heating system, comprising a crushing box and a reaction box, the crushing box is fixedly installed on the reaction box, and the same one is fixedly connected between the crushing box and the reaction box. The feeding hopper is fixed on the top of the crushing box. The crushing box is provided with a material guiding mechanism and a crushing mechanism. The bottom of the crushing box is fixed with a propulsion mechanism. The propulsion mechanism is located in the material guiding pipe. There is a pressing mechanism under the cam, a material guide table is fixed on the right side of the inside of the reaction box, a material push mechanism is rotated and inserted between the material guide table and the left side of the reaction box, and one end of the material push mechanism is connected with a transmission mechanism through a transmission mechanism. stirring mechanism. The invention promotes the sufficient reaction of the ash and the acidic reaction solution to form a porous structure.

Description

technical field [0001] The invention relates to the technical field of ash and slag treatment, in particular to an ash and slag treatment device used in a biomass heating system and a treatment method thereof. Background technique [0002] With the increasing demand for energy in society, fossil fuels as the main energy source are rapidly decreasing. Therefore, the search for a renewable alternative energy source has become the focus of general attention of the society. Biomass fuel heating among various renewable energy sources has been widely used due to its less environmental pollution. The available 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 firewood, wood scraps, tree roots, etc. The common points of these biomass fuels are: 1. The volatile content of the combustible base is very high, mostly above 80%; 2. The ash produced by its combustion has ...

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.
