Electrostatic dust collection double-layer sheet ventilation curtain wall

Abstract

The invention discloses an electrostatic dust collection double-layer sheet ventilation curtain wall structure. The electrostatic dust collection double-layer sheet ventilation curtain wall structure comprises positive plates on the two sides, a curtain wall inner layer sheet and an curtain wall outer layer sheet, wherein a ventilation opening is formed in the lower portion of the outer layer sheet, a corona wire with barbs serving as a negative electrode is arranged in a cavity between the inner layer sheet and the outer layer sheet, a row of shutter dust collection plates driven by a lower shaft are further arranged in the cavity, a dust collection groove is formed in the lower portion of the curtain wall, a junction box and a fan box with a fan inside are arranged on the upper portion of the curtain wall, ventilation openings are formed in the lower bottom face, making contact with the cavity, of the fan box and the side, facing the indoor space, of the fan box, and a rectifier for converting alternating current into direct current and a current sensor for detecting current changes of the shutter dust collection plates are arranged inside the junction box. According to the electrostatic dust collection double-layer sheet ventilation curtain wall, a common shutter sun shield is replaced with the shutter dust collection plates with the dust collection effect, the charging area and the dust collection area are arranged in the cavity, fresh air entering a room is cleaned through electrostatic dust collection, the energy-saving advantage and the sun-shading and ventilation effects of a traditional double-layer sheet ventilation curtain wall are achieved, the fresh air purification effect is further achieved, the structure is simple, the energy consumption is low, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of building energy conservation, and in particular relates to an electrostatic dust removal double-skin ventilation curtain wall. Background technique [0002] In recent years, building energy consumption accounts for an increasing proportion of global energy consumption, prompting the number of energy-efficient buildings to increase year by year, and building energy conservation and sustainable development are particularly important. Due to the light transmission and heat transfer characteristics of glass in traditional glass curtain walls, it will cause the problem of indoor overheating, and the energy consumption of air conditioning will increase accordingly. The double-layer leather curtain wall utilizes the cavity between the inner and outer skins to achieve natural ventilation in summer, take away part of the solar radiation heat entering the room, and reduce the cooling load in summer; it produces a g...

Problems solved by technology

However, the pure external circulation mode cannot utilize fresh air, and the long-term airtight environment will lead to poor indoor air quality, and the effect of using water mist for shading is negligible, which is not conducive to the indoor air environment, nor can it realize the sunshade function

Although there are a small number of existing technologies that have studied electrostatic dust removal and double-layer leather curtain walls, these technologies are still immature and have many shortcomings, such as unreasonable layout, unsatisfactory dust removal effect, and the need for daylighting is abandoned in order to achieve dust removal.
