A system for recycling ash blocks after burning industrial boiler biomass fuel

Abstract

The invention relates to a treatment system for reusing ash blocks after burning biomass fuel in industrial boilers, including a support, a crushing unit, a powder milling cylinder, a crushing unit, a fine grinding unit and a feeding unit, and a crushing unit is installed on the upper end of the support , the right end of the bracket is equipped with a powder milling cylinder, the powder milling cylinder is located at the lower end of the crushing unit, a crushing unit and a fine milling unit are arranged in the powder milling cylinder sequentially from top to bottom, and a feeding unit is arranged at the lower end of the powder milling cylinder; the present invention through crushing, The process of crushing and finely milling the three-stage crushing fully targets the properties of the ash block, so that the particle diameter of the finished product meets the requirements of fertilizers; the invention utilizes the brittleness of the ash block to complete the primary crushing of the broken ash block by means of crushing, so that The ash block can be crushed in the second stage by rolling, and the ash block can be crushed three times by fine grinding, and the three-stage crushing makes the ash block fully crushed layer by layer.

Description

technical field [0001] The invention relates to the technical field of solid waste recovery and reuse, in particular to a system for reusing ash blocks after burning biomass fuel in industrial boilers. Background technique [0002] At present, the problem of environmental pollution at home and abroad has been paid more and more attention by the whole society. As the power base of the entire national economy, industrial boilers burn loose coal, lack investment in environmental protection equipment, and cause serious air pollution due to boiler flue gas emissions, which is the cause of smog. One of the main culprits. [0003] In recent years, the country has advocated the use of biomass briquette fuel instead of coal. Due to the special properties of biomass, its content of ash, sulfur, nitrogen and other elements is much lower than that of coal. It is a clean and environmentally friendly energy source for combustion The biomass raw materials can be obtained locally, and the ...

AI Technical Summary

Problems solved by technology

However, the ash block is a product of combustion, which has problems such as brittleness, smoothness, and large size. It is difficult for the existing crushing machinery to sufficiently crush the ash block.

[0004] Now there are the following problems in the process of crushing the ash blocks: 1. Part of the ash blocks are too large and smooth, which causes the crushing machine to fail to roll them, so it needs to be crushed manually to make them meet the requirements of the crushing machine. 2. It is difficult for the existing equipment to crush the particle crystals in the ash block, making it difficult for the fertilizer to be absorbed by the field; 3. To bag the ash powder, it needs to be bagged by a person holding the bag, or the upper edge of the bag The sleeve is tied tightly on the unloading pipe, making it difficult to discharge the gas in the pouch of the pouch, which reduces the amount of single pouches and increases the cost
