A mobile and adjustable rotary jet enhances the local ventilation device

Abstract

The invention discloses a mobile adjustable rotary jet device for strengthening local air exhaust. The device includes an air exhaust port, a jet cavity, an exhaust pipe, a jet pipe, a fan box, a dust collection box and a three-way pipe; wherein, The air exhaust port communicates with one end of the exhaust pipe, and the other end of the exhaust pipe communicates with the dust collection box. The lower part of the dust collection box is provided with universal wheels, and the upper part of the dust collection box is connected with the fan box. A filtering device is provided between the dust collection box and the fan box, a fan is arranged in the fan box, the outlet of the fan is connected to the first pipe of the three-way pipe, and the second pipe of the three-way pipe is provided with a There is a damper, and the second pipe is connected with the indoor air; the third pipe of the three-way pipe is provided with a damper, and the third pipe communicates with one end of the jet pipe, and the other end of the jet pipe communicates with the jet chamber, and the jet The cavity is located outside the air exhaust port and arranged along the circumference of the air exhaust port, and the opening of the jet cavity is provided with a jet port. The device can effectively control local environmental pollution.

Description

technical field [0001] The invention relates to a local pollution control device, in particular to a mobile adjustable rotary jet device for enhancing local exhaust air. Background technique [0002] Inside industrial buildings, various pollutants associated with industrial production include particles, harmful gases, etc. These pollutants will invade the respiratory tract, come into contact with the human skin surface, or enter the human body through the digestive tract, resulting in lesions of human organs and systems, and will bring great harm to human health. However, its complex process conditions, especially in the process of ventilation renovation of existing industrial buildings, limited the distance between the local exhaust hood and the pollution source because the original design did not reserve space. Traditional local exhaust hoods are inefficient. For example, in a foundry, a large amount of high-temperature flue gas will be generated during the casting proce...

Problems solved by technology

However, this technology adds an additional set of jet-generating fans, which increases the initial investment and energy consumption of the project, and has relatively large noise, which limits the promotion of this technology.

At the same time, the air volume is fixed, the application scenarios are limited, and cannot be adjusted with the change of the process
