Air dust removing and sterilizing purification device for pipeline draught fan

Abstract

The invention discloses an air dust removing and sterilizing purification device for a pipeline draught fan. The air dust removing and sterilizing purification device for the pipeline draught fan comprises a fresh air feeding pipeline, a fresh air treatment device, a fresh air discharging pipeline and an air return pipeline. The fresh air feeding pipeline communicates the air return pipeline and the fresh air treatment device. The fresh air treatment device communicates with the fresh air discharging pipeline. The fresh air discharging pipeline communicates with the air return pipeline througha ventilation area. The fresh air feeding pipeline, the fresh air treatment device, the fresh air discharging pipeline, the ventilation area and the air return pipeline sequentially communicate and form a closed-loop ventilation circuit. A filter, a cooler, a heater, a draught fan and a first electronic dust removal and sterilization device are sequentially arranged inside the fresh air treatmentdevice. The air dust removing and sterilizing purification device for the pipeline draught fan further comprises a second electronic dust removing and sterilizing device and a dust concentration sensor. The second electronic dust removing and sterilizing device communicates with the air return pipeline and the ventilation area. The dust concentrator is located between the second electronic dust removing and sterilizing device and the ventilation area. The air dust removing and sterilizing purification device for the pipeline draught fan achieves more intelligent dust purification and dual dust removal, conducts sterilization, removes harmful gas and has excellent effects.

Description

technical field [0001] The invention relates to an indoor purification device, in particular to a purification device used for dust removal and sterilization of pipeline fan air. Background technique [0002] The air purification device is a household appliance used for indoor air ventilation, purification and sterilization. It is generally installed in the pipeline or placed in the wall, and the air in the transmission pipeline or the wall is used to ventilate, purify and clean the area connected to the pipeline or the wall. Sterilize. [0003] The air purification device generally includes an air inlet pipe, an air inlet processing device, an air outlet pipe and a return air pipe, which are connected in sequence to form a ventilation circuit. [0004] At present, most of the existing air purification devices are traditional household appliances such as air conditioners, range hoods, and duct fans. The function of dust concentration detection and alarm is single and canno...

AI Technical Summary

Problems solved by technology

Since the invention only realizes the functions of dust removal and ventilation, and a large amount of consumables are used for filtration, the cost is high and the function is single. It is not suitable for ventilation, dust removal, and sterilization in large-area ventilation areas. The effect is not good, and it does not have the effect of sterilization. Automation low level

[0006] Due to the special installation location of the purification device for air dust removal and sterilization of the ducted fan, it is impossible to monitor its operation in real time, and the working environment of the ducted fan is relatively harsh. The air inlet duct of the ducted fan is connected to the bedrooms and living rooms where people live. Yes, there are a lot of bacteria and dust in the pipes, which can easily be brought into the living room with the ventilation of the fan, causing respiratory system infection of the occupants
