Description

Technical Field

[0001] The utility model relates to the technical field of feed processing, in particular to an ozone treatment device for waste gas from fish meal processing. Background Art

[0002] Fish feed contains rich nutrients for farmed fish to eat and grow. The raw materials of fish feed include fish meal, which is mainly processed from fish meat. Fresh fish meat is separated, crushed, steamed, pressed, solid-liquid separated and dried to obtain fish meal. After further screening, crushing and cooling, the fish meal can be packaged. The packaged fish meal can be transported to the processing plant and mixed with other raw materials in corresponding proportions to make fish feed. During the drying process of fish meal, a large amount of waste gas will be generated. If these waste gases are directly discharged into the atmosphere, it will cause air pollution. In fish meal processing plants, waste gas from fish meal drying is collected and treated harmlessly. The most common treatment method is ozone treatment, which involves passing the collected waste gas into a container containing ozone to achieve deodorization and decomposition. However, the current ozone generators are basically located in fixed positions, and the ozone they produce cannot be quickly mixed with the waste gas, resulting in incomplete decomposition and deodorization of some waste gases. After the treatment time is completed, the waste gas is discharged into the air, causing air pollution, and the remaining waste gas will also affect the working environment of the staff.
