Purification type pipeline-free fresh air system

Abstract

The invention relates to a purification type pipeline-free fresh air system and belongs to the technical field of ventilation. The purification type pipeline-free fresh air system is composed of a plurality of positive pressure units and a plurality of negative pressure units. The purification type pipeline-free fresh air system is in a long strip shape and is formed by splicing curtain wall frames in an inlaid mode. An air outlet is a cross-sectional air outlet. A plurality of draught fans are arranged in the long-stripe-shaped structure and used for supplying air or exhausting air. A purification device is arranged at an air supply and air exhaust outlet. Electronic control systems and temperature sensing control systems are arranged on the draught fans. In a relatively airtight space, convection is formed by positive pressure devices and negative pressure devices. Through control of the electronic control systems, uninterrupted work is realized between the devices, and the 24-hour ventilation effect is achieved. The purification device guarantees fresh air at the air outlet. Dirt originally contained in the air is directionally exhausted. The space purification effect is achieved.

Description

technical field [0001] The invention relates to the technical field of ventilation, in particular to a purification type ductless fresh air system. Background technique [0002] In order to prevent the harmful substances produced during the production process from polluting the air in the workshop, the harmful substances are often captured on the spot through the exhaust hood or suction port, and transported to the purification equipment with pipelines for treatment. After meeting the emission standards, they are returned to Use or exhaust into the atmosphere, this is the local exhaust of the equipment. [0003] When there are many such equipment in production, and the local exhaust volume of each unit does not need to be large, for economic considerations, they are often connected as a whole with pipes to form a local exhaust system, and the whole system shares one Purification equipment and fans. [0004] In the local exhaust system, in order to achieve the effect of tra...

Problems solved by technology

[0005] Exhaust technology in residential or building applications in the prior art is mostly ventilated through ducts, and the air outlet is a longitudinal section, the ventilation path is long, the ventilation area is large, and the loss is large; when the traditional exhaust duct is installed, the construction It is difficult, requires many consumables, occupies a large area, and causes serious secondary pollution, which also affects the purification effect.
