[0002] Kiln furnace ash, commonly referred to as solid residues generated during the combustion or calcination process in various industrial kilns (such as cement kilns, lime kilns, ceramic kilns, etc.). It is mainly composed of unburned fuel residues, raw material decomposition products and added fluxes, etc.
[0003] Kiln furnace ash was often regarded as waste in the past, but with the development of resource recycling technology, it is now increasingly used in many fields. In the field of building materials, after proper treatment, furnace ash can be used as an additive for producing cement, concrete, bricks and other building materials, improving product performance and reducing cost. In soil conditioners, appropriate amount of furnace ash can be used to adjust soil pH value and increase soil fertility, especially suitable for the improvement of acid soil. Therefore, kiln furnace ash can be transported to the factory for processing and utilization, but kiln furnace ash contains a large amount of dust, which is easy to be blown up due to air flow during loading and unloading, resulting in dust raising.

[0024] The specific implementation process is as follows:
[0025] When the kiln ash is transported in the ash box, the feeding pipe 1 is installed on the ash box 5 and the fan 4 is started. Since the air inlet of the fan 4 is communicated with the inside of the feeding pipe 1, when the fan 4 is started, the air in the feeding pipe 1 is continuously drawn out by the operation of the fan 4, so that a continuous negative pressure state is formed in the inside of the feeding pipe 1. At this time, the kiln ash is poured into the feeding pipe 1. Under the action of gravity, the kiln ash falls into the ash box 5 through the feeding pipe 1 and the ash inlet. During the process of loading the kiln ash, the light dust is adsorbed on the wall of the filter pipe 2 under the action of negative pressure, so it will not float out of the feeding pipe 1. The dust adsorbed on the filter pipe 2 gradually increases in mass with the accumulation. When the mass of the accumulated dust is greater than the adsorption force, the dust falls from the filter pipe 2 to the ash box 5 under the attraction of gravity. At the same time, when the kiln ash is poured into the feeding pipe 1, the falling ash will also scrape off part of the dust adhered to the filter pipe 2.
