Description

Technical Field

[0001] This utility model relates to the field of drying tower technology, and in particular to a spray drying tower exhaust gas treatment device. Background Technology

[0002] Spray drying towers are equipment used for drying biological pesticides, pharmaceuticals, and food microorganisms. They are a drying process in which raw material liquid is put into an atomizer and separated into droplets, and hot air or other gases are used to directly contact the droplets to obtain powder products.

[0003] When spray drying towers treat exhaust gas, the exhaust gas may contain toxic gases and dust impurities. If it is discharged without treatment, it will cause serious environmental pollution. Existing exhaust gas treatment devices partially filter the exhaust gas, resulting in low efficiency. Furthermore, the exhaust gas is prone to leakage during reprocessing, leading to incomplete treatment. Therefore, we provide exhaust gas treatment devices for spray drying towers.
