Abstract

The invention discloses an airflow-direction-adjustable pollutant targeted long-distance multi-stage transport system which comprises a long-distance air supply device and an air exhaust device which are arranged in a building, and further comprises a movable relay air supply device. The long-distance air supply device is used for conveying air flow into the building; the movable relay air supply device is used for conveying the captured polluted airflow to the air exhaust device; and the exhaust device is used for exhausting the captured polluted airflow out of the building. The invention further discloses a pollutant targeted long-distance multi-stage transportation method with the adjustable airflow direction, and the method is achieved through the pollutant targeted long-distance multi-stage transportation system with the adjustable airflow direction. Particularly, a single or a plurality of movable relay air supply devices with adjustable angles are arranged in the building, so that the conveying direction of the air flow in the building is changed, and the effect of inducing the polluted air flow to diffuse towards a discharge port is achieved.

Description

technical field [0001] The invention belongs to the technical field of control of gaseous pollutants in large spaces, and in particular relates to a long-distance multi-stage transportation system and method for targeting pollutants with adjustable airflow direction. Background technique [0002] At present, industrial plants such as welding plants tend to be larger and larger, and the pollution sources in these plants are characterized by a large number and irregular locations. Comprehensive ventilation is to reduce the concentration of harmful gases in the entire workshop by introducing fresh air, and then discharge the diluted harmful gases out of the workshop through the exhaust port. This method has the disadvantages of poor ventilation efficiency and high energy consumption. Therefore, most enterprises have Local ventilation is used to control pollutants in the workshop, and the local exhaust hood has become the most commonly used local ventilation device. Local exhau...
