Air purifying system and air purifying method for double-layer curtain wall type building

Abstract

The invention relates to an air purifying system and an air purifying method for a double-layer curtain wall type building. An air purifying method and an air purifying method for ensuring that a purifying system in a double-layer curtain wall supplies clean air to the whole building are unavailable at present. The air purifying system is characterized by comprising an air purifying mechanism and a control system; the air purifying mechanism comprises an electrostatic dedusting system, a spraying system, a catalytic cracking module and an air monitoring module; an inner-layer building curtain wall is provided with inner-layer building windows which are used for guiding air to enter into the double-layer curtain wall type building; an air inlet, the static dedusting system, the spraying system, the catalytic cracking module, the air monitoring module, the inner-layer building windows and an air outlet are arranged in sequence from bottom to top. The air purifying method is used for purifying by taking tunnel wind naturally formed in the double-layer curtain wall as purifying airflow through sequentially adopting the electrostatic dedusting system and the catalytic cracking module. The air purifying system and the air purifying method are simple in structure, reasonable in design and capable of ensuring that the purifying system in the double-layer curtain wall supplies clean air to the whole building.

Description

technical field [0001] The invention relates to an air purification system and an air purification method in the field of air purification, in particular to an air purification system and an air purification method for a double-layer curtain wall type building, which are specially used in a double-layer curtain wall type building. Background technique [0002] Ventilated double-layer curtain wall, also known as hot aisle curtain wall, air circulation curtain wall, breathing curtain wall, ecological curtain wall, green curtain wall or active curtain wall, etc. There are air outlets at the upper and lower ends, and the height of the channel can be one or more floors. In the 1990s, double-layer glass curtain walls have been widely used in many European countries. It has a great effect on improving the air circulation, heat preservation, heat insulation and sound insulation functions of the entire building. Based on these characteristics, it has also begun to be promoted in Chin...

Problems solved by technology

A variety of air purifiers have been developed. These air purifiers are more efficient when used in small rooms, but they cannot achieve integrated air purification for the entire building. The existing building air purification systems mainly The fresh air system is adopted. The fresh air system realizes the air renewal in the whole building by exchanging outdoor and indoor air. For smog and harmful polluting gases, the fresh air system adopts the same purification mode as ordinary indoor air purifiers, that is, HEPA removes particulate pollutants ( PM10, PM2.5, etc.), activated carbon removes harmful gas pollutants (formaldehyde, TVOC, etc.), due to the limitation of the service life of the HEPA filter layer and the characteristics of saturated adsorption of activated carbon, the fresh air system has low purification efficiency and needs Serious problems such as continuous power consumption and expensive maintenance costs

In order to realize the air circulation of the building, the double curtain wall structure can replace the fresh air system of the building to a certain extent or greatly reduce the load of the fresh air system. effective solution

[0004] There are also some air purification devices used in double-layer curtain wall structures, such as a Chinese patent with a publication date of November 07, 2007 and a publication number of CN200970371, which discloses an air purification device for a glass curtain wall building. The device is connected to a control system. The control system is connected to the solar photovoltaic panel placed in the space enclosed by the double-glazed glass curtain wall through wires. The air purification device converts the energy transmitted from sunlight to the glass into electrical energy through the control system. In this way, the air purification system is started to purify the indoor air, so as to achieve the purpose of making full use of energy and purifying the air. The air purification device is still used in an independent room with a small space in essence, and it cannot realize the integration of the whole building. Air purification

Another example is that the publication date is August 22, 2007, and the Chinese patent publication number CN2937285 discloses a modular functional device for a double-layer curtain wall. The modular functional device for a double-layer curtain wall includes an outer upper horizontal frame and a The middle horizontal frame of the outer layer is fixedly installed with a ventilation volume control device between the upper horizontal frame of the outer layer and the middle horizontal frame of the outer layer. An air filter and purification device is installed at the upper end of the vent of the ventilation volume control device. A water circulation humidification pipe is installed above, and the water inlet and outlet of the water circulation humidification pipe are connected with fire joints, and are connected with the main water inlet pipe and the main water outlet pipe. Filter the air to achieve the purpose of purifying the air, the air purification effect is poor, and the daily maintenance cost is high

[0005] To sum up, there is currently no air purification system and air purification method for a double-layer curtain wall type building with a simple structure and reasonable design that ensures that the purification system in the double-layer curtain wall provides clean air for the entire building.
