Description

Portable air pollution control device

Technical Field

The utility model relates to a portable air pollution control device relates to air pollution control device technical field.

Background

In recent years, the socio-economy of China is rapidly developed, but the environmental damage caused by the socio-economy is increasingly serious, especially the atmospheric pollution, a large-scale and serious-degree haze weather appears in the whole country for a while, PM2.5 is in an explosion state, and the serious atmospheric pollution causes extremely bad influence on the life and the body health of people. Therefore, the treatment of air pollution is not slow. In the current air pollution control, however, the emission of toxic substances in enclosed spaces is extremely harmful, for example, in the paint spray booth of automobiles, which are painted. The vehicle booth is equipped with exhaust fans that absorb contaminants from the air from the booth for downstream collection.

Although it is possible to paint an entire vehicle in the enclosed space described above, paint touch-up is typically applied to only a portion of the vehicle in a relatively open area, without the need for a protective shed or other protective environment. Thus, hazardous air pollutants (e.g., volatile organic compounds, hexavalent chromium, and other components of paint) can enter a relatively confined environment and pose a hazard to persons in that environment. Since it is not feasible to construct a closed spray booth, such spray painting is required at several random locations so that fugitive particles enter a relatively confined environment.

Given the potential health hazards of airborne contaminants, fugitive particulate particles must be captured in an environment that may be hazardous to personal health. Accordingly, it is a primary object of the present invention to provide an air pollution control device that is movable to a place of origin of pollutants.

It is another object of the present invention to provide an air pollution control device having a filter system for capturing and retaining fugitive pollutants.

Disclosure of Invention

In view of the above, the present invention provides a portable air pollution control device, which overcomes the drawbacks of the prior art.

According to the utility model discloses, a portable air pollution control device is provided. The utility model discloses can catch the air contaminant that exists in the relatively narrow environment. The portable air pollution control device comprises an air pollutant collecting device which is movable to a pollutant origin and which is fitted with at least one collector member. A vacuum system is mounted within the capturing device and is in communication with the collector member to draw airborne contaminants into the capturing device through the collector member. In practice, capturing the contaminants is accomplished by a filter system within the capture device. The filter system may comprise one filter or more than one same or different filters.

Preferably, an activated carbon filter may be included in the filter system to trap and retain volatile organic compounds; the paint spraying filter is used for collecting general pollutants; a high efficiency air particulate filter for collecting chromium and other paint related metal contaminants.

Preferably, the filter system can accommodate multiple filters simultaneously, thereby capturing multiple contaminants. By placing the collector member in close proximity to the activity causing the contamination (e.g. paint make-up) and operating the collector member whilst the activity is in progress, particles are drawn into the air contaminant collection device and fugitive particles are captured therein.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and the described embodiments are only some embodiments, not all embodiments, of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, 2 and 3, the portable air pollution control device 1 has two conical hoods 2 constructed in the same manner as the collector members. Each conical hood 2 communicates with a flexible hose 3 leading from the proximal end of said conical hood 2 to a respective housing inlet 4 of a housing 6. A conventional clamp 7, a conventional clamp 8, is connected to each conical shroud 2 and the housing inlet 4 at the end that supports each flexible hose 3. An articulated outer support 9 is associated with each flexible hose 3 and is connected to a plurality of hoses 10.

As shown in fig. 2, the door 5 closes and seals the housing 6 so that a pressure differential can be established, drawing air into the sealed housing 6 through the conical shroud 2.

A plurality of filters are located within the sealed housing 6 to capture and retain volatile contaminants. Preferably, the primary filter 11 and the secondary filter 12 are positioned substantially next to the housing inlet 4, thus being the first filter that receives the inhaled gas through the conical enclosure 2. Immediately adjacent to the carbon filter 13 is a hepa filter 14. Using the hepa filter 14 as the ultimate destination for the extracted contaminants helps to ensure the capture efficiency of the portable air pollution control device 1.

A vacuum system is provided within the sealed housing 6, said vacuum system comprising a conventional fan (not shown) driven by a motor 15, said motor 15 being supported by a bracket 16 and protected by a protective member 17. The angled louvered vents 18 allow exhaust gases to pass after passing through the filter system. The differential pressure gauge 19 is used to indicate the efficiency and cleanliness of the filter for replacement of the filter at any time. The pressure differential should range between 1-10 inches of water depending on the type of filter. Mobility is provided by four standard wheel assemblies 20.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
