　　The external suction hood is located near the smoke source, and the suction close to the smoking port will suck the smoke into the hood. It has little influence on production and operation, convenient installation and maintenance, but it increases the intake of surrounding air, large exhaust air volume, low efficiency and poor control ability for harmful substances. It is mainly used in the situation where pollutants cannot be sealed due to technical requirements or operating conditions.
