Technical Field

The invention belongs to the technical field of air purification, and relates to an inflatable gas collecting hood and application of an inflatable ventilating duct.

Background

In daily life, people cannot avoid being in an aggregated environment, such as: family gatherings, restaurant gatherings, public places, hospitals, offices, and the like. Air in these concentrated environments can sometimes cause harm to people, such as: transmission of respiratory infectious diseases, second-hand smoke, etc.; in addition, some specific places may also cause harm to people, such as: household kitchens, restaurant kitchens, production plants, etc. produce harmful gases. The solution is as follows: some fresh air systems are adopted in the environment space, for example, fresh air is injected below the environment, polluted air is exhausted above the head of a person in the environment, the fresh air is breathed by the person, and gas or harmful gas exhaled by the person is exhausted outdoors. The air collecting hood and the ventilation pipeline are often used in the fresh air system of the ambient air, and most of the traditional air collecting hood and the ventilation pipeline are made of metal or plastic, so that the fresh air system has the defects of heavy weight, complex installation structure, high construction difficulty, high manufacturing cost, inconvenience in maintenance and cleaning and the like.

Summary of the invention

In view of the above problems in the fresh air system of air in the environmental space, the present invention provides an inflatable gas collecting hood and an inflatable ventilation duct, which can effectively solve the above problems in the background art.

In order to achieve the purpose, the invention provides the following technical scheme:

the method comprises the following steps of processing an inner layer and an outer layer into a closed air chamber by utilizing the prior art, such as the technologies of inflating a castle, an aluminum film balloon and the like, selecting fabrics made of materials such as oxford, an aluminum film, PVC, PA, PE and the like, blanking the inner layer and the outer layer according to a preset shape, adding a lacing wire between the inner layer and the outer layer, bonding or welding and the like, inflating the inner layer and the outer layer from an inflation inlet, expanding the whole prefabricated structure by using the inner gas after inflation, and achieving the required shape; can be processed into ventilation equipment with any shape, such as straight pipes, bent pipes, large and small ends, four-way joints and the like of gas collecting hoods and ventilation pipelines.

Selecting different materials according to different use scenes, such as fire-proof grade and environmental protection grade; different fresh air system structures can be selected according to different use scenes, for example, a fresh air system with a complex structure is selected in a large public place; the small smoke exhauster for household use, such as kitchen fume hood or second-hand smoke prevention, can be realized by directly adopting an inflatable gas collecting hood and a section of inflatable ventilating duct and additionally arranging an exhaust fan.

The application of the inflatable gas collecting hood and the inflatable ventilating duct is illustrated by only one restaurant, and the fresh air system in the restaurant comprises a fan, an air injection pipeline, the inflatable gas collecting hood, the inflatable ventilating duct, a PVC (polyvinyl chloride) air exhaust main pipeline, a metal air exhaust wall-through pipeline, an air heater, an outdoor metal air exhaust pipeline and an exhaust fan; the inflatable gas collecting hood is in butt joint with an inflatable ventilating duct, the inflatable ventilating duct is in butt joint with an indoor PVC air exhaust main pipeline, the PVC air exhaust main pipeline is in butt joint with a metal air exhaust wall penetrating pipeline, the metal air exhaust wall penetrating pipeline is in butt joint with an air heater, the air heater is in butt joint with an outdoor metal air exhaust pipeline, and the outdoor metal air exhaust pipeline is in butt joint with an exhaust fan. The PVC air exhaust main pipeline, the metal air exhaust wall-through pipeline, the air heater and the outdoor metal air exhaust pipeline are used for heating and disinfecting the air exhaust body at the tail part of the air exhaust pipeline at high temperature, and if not required, the air exhaust pipeline can be completely replaced by an inflatable ventilating pipeline.

It should be noted here that the reasons for selecting the inflatable gas-collecting hood and the inflatable ventilation duct are as follows:

1. in the fresh air system, fresh air is blown upwards vertically from below by a fan in the environment, gas aerosol, second-hand smoke, harmful gas and the like exhaled by people in the environment are blown upwards, are sucked away by an inflatable gas collecting hood above the human body and are finally discharged through an inflatable ventilating duct, and therefore the harm opportunities of virus propagation, second-hand smoke, harmful gas and the like in the space where people are located to the human body are reduced.

2. Because the environment of people is different, the facility and the structural arrangement of a fresh air system are also different, the traditional construction difficulty is large like metal and PVC pipelines, and the inflatable gas collecting hood and the inflatable ventilating pipeline are adopted, because of the characteristics of flexibility and lightness, some people only need to select two hanging points, the previous installation of more fixing supports on the wall is completely cancelled, the construction difficulty is reduced, and the construction efficiency is improved.

3. The indoor ventilation system is basically normal temperature air, metal or PVC pipelines are not needed, the material and processing cost of products can be greatly reduced, and meanwhile, the construction cost is also greatly reduced.

4. Compared with metal or plastic, the inflatable product is relatively easy to process for complex structures, and the outer surfaces of the inflatable gas collecting hood and the inflatable ventilating duct can be processed into various current situations, such as an elbow, a reducer, a cross joint and the like in a ventilating system; in addition, the outer layers of the inflatable gas collecting hood and the inflatable ventilating duct can be processed into various artistic and cartoon shapes, so that the aesthetic feeling is increased; besides, the roller shutters are additionally arranged around the edge of the inflatable gas-collecting hood, so that an independent space can be formed.

5. Because the new trend system of some environment is temporary, use back inflatable gas collecting channel and inflatable air pipe also convenient to detach, the management of collection, storage more convenient to use for from time to time.

6. The gas-collecting hood and the exhaust duct are used only in harmful environment and can be polluted after long-term use, and the inflatable gas-collecting hood and the inflatable ventilating duct have light weight and simple installation structure, and are very convenient to detach, clean and maintain.
