Description

Indoor inflatable gas collecting channel

Technical Field

The invention belongs to the technical field of air purification, and relates to an indoor inflatable gas-collecting hood.

Background

Among all respiratory infections, especially the current new crown pneumonia infection, one of the major routes of infection is through aerosols and droplets in the air. In an enclosed space, exhaled gas droplets of a person can fly as far as eight meters away, and exhaled aerosols containing viruses can be suspended in air for several hours. Although the transmission rate can be greatly reduced by wearing the mask and ventilating indoor duty, the ventilation is difficult to realize in some occasions, such as restaurants and restaurants, and the ventilation is difficult to realize in duty, so that are more duty? Perhaps, new aerosol with virus is generated in the air just closing a window, and China has won a certain victory in epidemic situation control, but the cost is high, and foreign situations are worse. Especially, the air is dry and cold when the winter comes, the method is more suitable for the survival and the transmission of the virus, and the new coronavirus is also entwined around us at any time.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned realistic problems existing in the prevention and control of respiratory infectious diseases such as new coronary pneumonia, the utility model provides an indoor inflatable gas collecting channel, which is used for the epidemic prevention system to effectively solve the problems existing in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

an indoor inflatable gas-collecting hood comprises a fan, an air injection pipeline, an inflatable gas-collecting hood, an inflatable exhaust pipeline, a PVC exhaust main pipeline, a metal exhaust wall-through pipeline, an air heater, an outdoor metal exhaust pipeline and an exhaust fan; the inflatable gas collecting hood is in butt joint with an inflatable exhaust duct, the inflatable exhaust duct is in butt joint with an indoor PVC exhaust main duct, the PVC exhaust main duct is in butt joint with a metal exhaust wall penetrating pipeline, the metal exhaust wall penetrating pipeline is in butt joint with an air heater, the air heater is in butt joint with an outdoor metal exhaust duct, and the outdoor metal exhaust duct is in butt joint with an exhaust fan.

It should be noted here that the reason for selecting the inflatable gas collecting hood and the inflatable exhaust duct is as follows:

1. among the respiratory infectious disease, especially present new crown pneumonia infectious disease, aerosol and the droplet in the air are main propagation way the utility model discloses in, the fan squeezes into air injection pipeline with high-pressure air through the pipeline under the table, and the spaced one row of nozzle of opening in air injection pipeline top, and high-pressure air is by the nozzle blowout, forms one air curtain from bottom to top in the front of people, and the gas of people's exhalation can be blown upwards by the air curtain that forms on the air injection pipeline at once, is collected and is discharged, the disinfection by the inflatable gas collecting hood of negative pressure simultaneously, just there is not viral dwell time indoor at all, has just also blocked the propagation.

2. Because the field size that needs the epidemic prevention, the arrangement of indoor environment and facility is different, the construction degree of difficulty of tradition like metal, PVC pipeline is big, and adopt inflatable gas collecting channel and inflatable exhaust duct, because all be flexible and light characteristics, as long as select two hanging points can, the construction is simple, be convenient for large tracts of land construction.

3. The indoor ventilation is basically normal temperature air, metal or PVC pipelines are not needed, the material cost can be greatly saved, the large-area popularization is facilitated, and the possibility of thoroughly blocking the spread of respiratory infectious diseases in the whole society as early as possible is increased.

4. The processing procedure of the inflatable product is simple, the outer surfaces of the inflatable gas-collecting hood and the inflatable exhaust pipeline can be processed into various current situations, for example, the inflatable gas-collecting hood and the inflatable exhaust pipeline can be processed into various artistic and cartoon shapes in a restaurant to increase the pleasure of people, in addition, the roller shutters can be additionally arranged around the edge of the inflatable gas-collecting hood, the pollution to the surrounding air can be further prevented, the function of ensuring the personal privacy is also achieved, and the like.

5. Because the epidemic outbreak is temporary, after the epidemic situation passes, in order to resume indoor original arrangement, inflatable gas collecting channel and inflatable exhaust duct also are convenient for dismantle, are more convenient for collect the management to use from time to time.

In the room, the fresh air can be breathed by people, the exhaled air is discharged by the inflatable gas collecting hood and the inflatable exhaust pipeline and is disinfected for the second time, and then the possibility of spreading viruses through human body droplets and aerosol is cut off.
