Description

Technical Field

[0001] The utility model relates to the field of production and processing, in particular to a high-temperature resistant hood. Background Art

[0002] The acid separator is a tower accessory that evenly distributes the acid on the surface of the packing. It is usually used to remove or neutralize the acidic components in the exhaust gas to reduce pollution to the environment or corrosion to the equipment. At the same time, friction heat will be generated when the gas flows inside the acid separator, especially when the high-speed airflow or gas passes through the packing layer. The friction heat will increase the temperature of the gas. The wind hood is used to discharge the treated exhaust gas. In order to ensure the effective operation and safety of the exhaust gas treatment system, the two need to be used together.

[0003] However, in the prior art, the wind hood can only accelerate the emission of gas, but some acidic substances will still exist in the exhaust gas after being treated by the acid separator, and acidic gas will still cause environmental pollution. At the same time, when the gas temperature is too high and flows through the wind hood, the wind hood is easily damaged due to long-term high temperature contact.

[0004] For this reason, we propose a high temperature resistant hood. Utility Model Content
