How to deal with dust problems when producing organic fertilizer

 When organic fertilizer equipment is used, most of it uses organic waste and perishable substances. Therefore, odor is generated when the raw material is stored and the storage site is unloaded. In addition, dust and unpleasant gases are generated in the fields of raw materials, auxiliary materials, composting places, and platforms between the fermentation facilities where the trucks enter and exit. Auxiliary materials such as rice husks and sawdust do not produce unpleasant gases, but they generate a large amount of dust when they are removed.

When the rice husk is pulverized by using a pulverizer in an organic fertilizer facility, dust and water vapor are generated when the pulverized rice husk is transported and transported. In the case of pulverizing the pruning, if the shearing pulverizer is used, substantially no dust is generated, but if the prune is pulverized by the high-speed rotary pulverization and the air transportation, a considerable amount of dust and noise are generated. In the mixing equipment, various raw materials are put into the mixer, especially when the composting of the small amount of water and the discharge of the mixed raw materials are generated, and odor and dust are also generated.

In the fermentation process, the decomposition of organic matter produces ammonia gas. After the raw materials are supplied to the fermentation facility, the compost is discharged through the fermentation facility, and odor and dust are generated during repeated operations in the secondary fermentation tank. The decomposition of organic matter raises the temperature of raw materials and produces a large amount of water. During the process of repeated operations, water vapor, dust and gas are mixed together, resulting in a state of white fog in the fermentation chamber of the organic fertilizer equipment. The odor and water vapor generated during the fermentation are significantly reduced as the end of first fermentation, and substantially disappear when the secondary fermentation is completed. Compost with less moisture is accompanied by a decrease in moisture, which in turn produces dust. During the repeated use of the secondary fermentation facility, both water vapor and dust are generated.

Now the state is becoming more and stricter in the management of environmental protection. When organic fertilizer equipment is used to make organic fertilizers, a small amount of dust will also appear. This requires the dust to be disposed of. When the whole organic fertilizer equipment is working, the dryer process is the most prone to dust, because the material will produce a certain amount of fine dust when it is dried. We can use the cyclone or water curtain dust collector to extract and filter the dust, thus solving the dust problem. And friends with limited funds can build a small dust room next to the dryer, and the dust is pumped into the dust chamber for static standing.
