Intelligent composite type electrostatic fresh air purifier

Abstract

The invention discloses an intelligent composite type electrostatic fresh air purifier. The intelligent composite type electrostatic fresh air purifier comprises a shell and a control system. A self-balancing type fresh air inlet is formed in an outdoor side plate of the shell. A flow equalizing air supply port is formed in an indoor side plate of the shell. A temperature and humidity sensor, an indoor particulate mass concentration sensor and a carbon dioxide concentration sensor are arranged at the flow equalizing air supply port in the shell. An outdoor particulate mass concentration sensor, an electrostatic filtering section, an antimicrobial electret filter, an activated carbon filter and a silent cross-flow fan are sequentially arranged from the self-balancing fresh air inlet to the flow equalizing air supply port in the shell. A corona wire and dust collection plates are arranged in the electrostatic filtering section and are connected with an adjustable direct-current power supply. According to the intelligent composite type electrostatic fresh air purifier, by means of the combination which can regulate the filtering efficiency and is composed of an electrostatic filter and a fiber filter, resistance of the whole filtering section is reduced under the condition of not sacrificing the filtering efficiency, and meanwhile the running efficiency of fresh air purification devices is improved.

Description

technical field [0001] The invention relates to an intelligent composite electrostatic fresh air purifier. Background technique [0002] Indoor air quality directly affects people's health and comfort. The sources and types of indoor pollutants are increasing day by day, and the airtightness of buildings is increasing, which makes it difficult for indoor pollutants to spread and increases the chances of people indoors coming into contact with pollutants. At this time, introducing fresh air into the room and exhausting indoor unclean air can effectively improve the indoor air quality. However, in a location with high population density and building density in the downtown area, the quality of fresh air is degraded due to vehicle exhaust, industrial pollution, garbage incineration, and road dust. If the concentration of pollutants in the outdoor air exceeds the control index of environmental parameters, in this environment Directly introduced fresh air not only fails to dilu...

Problems solved by technology

Disadvantages of this design: 1) The negative ion generator will produce ozone, a small amount of ozone is harmless to the human body, but excessive ozone will combine with some organic matter to produce carcinogens; 2) The ionized air under the high pressure of the negative ion generator may decompose nitrogen group 3) Negative ion generators may cause static electric shocks, resulting in blackening of indoor walls; 4) When the outdoor wind environment changes, the design cannot effectively deal with 5) The design does not design heat preservation and noise reduction; 6) The airflow at the air outlet is a horizontal jet, and the airflow is not easy to reach people's breathing area

Disadvantages of this design: 1) The filter is equipped with three filters of coarse-effect filter, medium-efficiency filter and high-efficiency filter, and the flow channel resistance cannot be overcome by the cross-flow fan; 2) The air inlet is not designed with effective self-balancing measures ; 3) There is no effective thermal insulation and noise reduction measures designed in the flow channel; 4) The airflow at the air outlet is a horizontal jet, and the airflow is difficult to reach people's breathing area

However, the concentration of particulate matter in the outdoor air is constantly changing. When the outdoor pollution is serious and the concentration of particulate matter is high, the use of an appropriate fiber filter can purify the outdoor air; but when the outdoor air is good and the concentration of particulate matter is low , the outdoor air can be purified to a level that meets the health requirements of the human body without the need for a filter with a high filtration level. At this time, the high resistance of the fiber filter will cause unnecessary waste of energy for the fresh air purification equipment, and will also increase The noise and vibration of fresh air fans affect comfort and safety
