Abstract

PURPOSE:To substantially surely execute the deodorization and cleaning of polluted air contg. org. compd. by executing plural times of deodorization and cleaning operations by means of a foaming filter, cyclone and deodorizing filter. CONSTITUTION:The polluted air contg. org. compd. in a printing office, painting site, etc., is conducted through the foaming filter 3 into the cyclone by a suction fan 16. The air is subjected to the 1st cleaning by the chemical liquid foam 3a generated on the upper side of the filter 3 and is then cleaned by contacting with the mist-like chemical liquid sprayed from a swirl injection nozzle 5. The fine particles of the chemical liquid stuck with the org. compd. falls through the filter 3 into a vessel 13 and is cyclically used. The polluted air out of the cyclone 1 passes through a throttling part 4 and is further subjected to the cleaning effect by the deodorizing filter 9, then the air is returned as the clean air into the room via a discharge fan 11.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a deodorizing device, and more particularly to a deodorizing device for air containing organic compounds in a workplace.

[Prior Art] For example, in printing shops or painting sites, hydrocarbons such as benzene and toluene, ketones such as acetone and methyl ethyl ketone, alcohols such as methanol and ethanol, aldehydes such as formaldehyde and acetaldehyde, and others are used. Contains a lot in the air.

Air containing such organic compounds not only causes odor pollution but also has an extremely large effect on the human body, and regulations regarding this are becoming increasingly strict.

[Problems to be Solved by the Invention] However, deodorizing devices that remove these harmful and odor-causing organic compounds do not use activated carbon, etc., or neutralize them by generating other odors. It did not remove organic compounds reliably, merely changing the fragrance to a scent that is pleasant to humans.

c. Means for Solving Problems] In the present invention, in order to solve the above problems,
Air containing organic compounds is guided into the cyclone through a foam filter, and is brought into contact with the atomized vortex of the chemical solution generated within the cyclone, causing the organic compounds to adhere to the fine particles of the chemical solution, which are then dropped together with the chemical solution and collected, and then removed from the cyclone. A structure was adopted in which the exiting air is circulated back into the room via a deodorizing filter.

[Function] When the above-mentioned structure is adopted, the contaminated air containing organic compounds is first subjected to the first cleaning action by the chemical bubbles generated in the foam filter section, and then by the atomized vortex flow of the chemical liquid in the cyclone. Upon contact, the organic compound undergoes a second and thorough cleaning action, and the organic compound falls together with the fine particles of the chemical solution, becoming the basis for generating chemical foam in the foam filter area, and is recovered through the foam filter. , reused.

In addition, the air that exits the cyclone is filtered through a deodorizing filter.
After receiving the second cleaning action, it is circulated back into the room.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

Figure 1 and the following illustrate an example of undeveloped IJI.
FIG. 1 shows the overall structure.

In the figure, the symbol l indicates a cyclone, which is constructed as a hollow cylinder with a large diameter in the center, and an opening 2 at the lower end serves as an outlet for a chemical solution, which will be described later, as well as an inlet for contaminated air. It has become.

A foam filter 3 made of foamed synthetic resin is provided so as to close this opening 2.

This foam filter 3 has the function of allowing air to pass through as well as allowing the chemical solution to pass through.

A constriction part 4 is formed at the upper end of the cyclone l,
A vortex jet nozzle 5 is provided facing this constriction portion 4 .

This nozzle 5 is connected to a high-pressure pump 7 via a discharge pipe 6, and generates the chemical solution in the cyclone 1 as a mist-like vortex.

Further, the constricted part 4 of the cyclone is continuous with the enlarged diameter part 8, and the enlarged diameter part 8 is provided with a deodorizing filter 9.

Furthermore, this enlarged diameter portion 8 is connected to an exhaust fan 11 via a conduit lO.
The exhaust fan 11 is connected to the exhaust port 12.

On the other hand, a chemical liquid container 13 is removably arranged below the cyclone l, and a chemical liquid 14 is stored therein.

This chemical solution 14 has a surfactant as its main base, and contains chlorophyll and other deodorants.

One end of piping 15 is inserted into this container 13,
The other end of the pipe 15 is connected to the high pressure pump 7.

The reference numeral 16 is a fan that draws in contaminated air.

The main body of the deodorizing device having the above-described structure is housed in a compact and elongated vertical casing 17 as shown in FIG.

The front surface of this casing 17 is a door 18 that can be opened and closed for maintenance purposes, and below this door 18 there is a suction port 1 with a louver structure or a mesh structure corresponding to a suction fan 16.
9, and an outlet 20 having a similar structure is provided at the upper end.

Next, the operation of this embodiment configured as described above will be explained.

When the power switch is turned on, the high pressure pump 7 and fan 11
．． 16 starts operating.

The chemical solution 14 in the container 13 is sucked by the high-pressure pump 7 through the tube 15 and sent to the vortex jet nozzle 5 through the piping 6.

Then, the chemical solution turns into fine particles in the form of mist and descends in the cyclone 1 in the form of a vortex.

In this state, the suction fan 16 guides contaminated air containing organic compounds from the opening 2 into the cyclone 1.

Since the interior of the cyclone 1 is in a negative pressure state due to the operation of the exhaust fan 11, contaminated air is guided into the cyclone 1 via the foam filter 3.

When passing through the foam filter 3, the chemical liquid impregnated in the foam filter 3 is subjected to a foaming action by the blowing of contaminated air, and chemical liquid bubbles 3a are generated above the foam filter 3.

A part of the organic compound adheres to this chemical bubble, and the first
Receive the cleaning action for the second time.

Of course, there are many organic compounds that adhere to the foam filter 3 itself.

In addition, since the number of chemical bubbles is extremely large and they burst one after another, the cleaning effect is similar to that of ultrasonic cleaning, and organic compounds and fine dust attached to the chemical liquid are removed.

The contaminated air that has undergone the cleaning action of the foam filter 3 comes into contact with the atomized chemical solution that is TKed in the form of a vortex, and organic compounds adhere to the fine particles of the chemical solution, which are transmitted along the wall surface of the cyclone 1 or directly. It falls and is guided to the foaming filter 3 side, becomes a base for generating chemical foam, and also passes through the foaming filter 3 and falls into the container 13.

This chemical solution is recycled and used.

Of course, chemical solutions that have been used for a certain period of time must be replaced.

On the other hand, the air exiting the cyclone 1 passes through the constriction section 4 and the deodorizing filter 9, and is further subjected to cleaning action by the exhaust fan ■
1 and returned to the room as cleaning air.

In this way, the contaminated air containing organic matter is washed multiple times and is returned indoors after being completely deodorized and cleaned, so the discharged air is completely purified and has an extremely effective deodorizing effect. big.

Note that an activated carbon filter 12a or the like may be provided at the discharge port 12 if necessary.

[Effect 1] As is clear from the above explanation, according to the present invention, deodorizing and cleaning actions can be performed multiple times using a foam filter, a cyclone, and a deodorizing filter, and organic compounds, which have been inseparable until now, can be removed. Contaminated air can be almost certainly deodorized and cleaned.
