Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wet-type deodorizer that purifies the air by impregnating a deodorizing filter with a deodorizing liquid to remove odors in passing air.

(Prior art) Dry deodorization systems using adsorption, such as activated carbon filters, are common and widely used as deodorizers, but in recent years, deodorizing liquids containing plant essential oils as the main ingredient have become available. Wet methods for processing have come to be used because of their high deodorizing performance; for example,
This is a device known from Publication No. 7614.

(Problems to be Solved by the Invention) A conventional wet type deodorizing machine has a basic structure in which deodorizing liquid is sprayed onto a deodorizing filter using a spray nozzle, and the amount of sprayed liquid is adjusted according to the atmospheric concentration of malodorous gas components. However,
In reality, the particle size of the sprayed liquid is large and it is difficult to spread it evenly onto the deodorizing filter, and the liquid drips from the deodorizing filter, resulting in a decrease in deodorizing efficiency and damage to peripheral equipment. There were problems such as contamination, and there was also the problem of increased moisture in the air to be treated.

In view of these problems, the present invention enables uniform spraying of liquid onto a deodorizing filter, facilitates atomization of the deodorizing liquid, and realizes rational management of liquid consumption. By doing so, the purpose of the invention is to eliminate the drawbacks of the conventional technology and play a role in promoting practical application.

), and a switching device (7) for controlling the opening and closing of the switching valve Oa, inside the casing (1). It is formed by the upper stage element side and the lower stage element Q'6 which are horizontally arranged in upper and lower two stages with a gap between them, and the lower stage element 0
The bottom of the spray nozzle (4) has an inclined surface structure where the front, rear, left and right sides, i + the center part, have the lowest level lower than the other parts, and the spray nozzle (4) has - m - both the element sides, α The pressure vessel (5) is placed in the middle of the hot water so that it can be sprayed into the gap between the two elements, and the pressure vessel (5) is held in an inverted position with the spout facing downward. The opening/closing device (7) is formed by an opening/closing lever 061 connected to the spring-loaded push rod of the opening/closing valve 00, and an electromagnetic solenoid aη that swings the lever α0 toward the valve opening side by excitation. Features.

Furthermore, the present invention provides a configuration in which the upper stage element (2) of the deodorizing filter (3) has a narrow inclined passage that intersects at an acute angle with respect to the upwardly flowing air, and the opening/closing device (7) is configured to Corresponding to the air volume, the pulse interval is shortened when the air volume is large, and the pulse interval is lengthened when the air volume is small. The opening/closing device (7) is connected to the fan (
2) A configuration in which the opening/closing valve is opened and closed periodically by outputting a pulse at a predetermined period with a wide pulse width when the air volume is large and a narrow pulse width when the air volume is small, corresponding to the air volume. It is a preferred embodiment that each of the following is specified in the invention of claim 1.

(Function) In the present invention, the deodorizing filter (3) is formed by the two upper and lower elements Q2) and 031, and the deodorizing liquid is sprayed into the gap in the middle, so that it is effective to prevent leakage outside the filter. Moreover, the liquid can be sprayed evenly.

Furthermore, since the deodorizing liquid is ejected using liquefied gas, the sprayed liquid can be effectively made into fine particles under high pressure, and the deodorizing filter (3) can be uniformly impregnated with the deodorizing liquid.

In the deodorizing filter (3), the bottom surface of the lower element 0■ has an inclined surface structure, so that the residual state of the deodorizing liquid agent can be concentrated in one place, which is convenient for predicting the filter life.

Furthermore, since the pressure vessel (5) is held in an inverted position, the deodorizing liquid can be used to the last drop.

According to a second aspect of the present invention, since the upper stage element α has an inclined narrow passage structure, the sprayed liquid particles are difficult to be scattered outside by the air current, and moisture is not introduced into the processing air.

On the other hand, in claims 3 and 4, since the amount of spray per unit time is adjusted depending on the amount of air blown, it is possible to replenish saliva in accordance with the degree of foul odor contamination of the air to be treated.

(Embodiments) Hereinafter, the contents of embodiments of the present invention will be explained based on the accompanying drawings.

The illustrated deodorizer is a wall-mounted deodorizer according to the present invention, and has a suction port 00.
) in the bottom surface and the outlet OD in the top surface, inside the casing (1), a fan for air circulation (2), a deodorizing filter (3), a spray nozzle (4), a pressure vessel (5), It contains a liquid sending pipe (6), a switchgear (7), and a control board (8).

The fan (2) and the deodorizing filter (3) are
3) are arranged in a vertical relationship close to the suction port αφ side, and the filter (3) is arranged so as to cross the flow path of the air flowing upwardly by the fan (2). (3) consists of an upper element (b) and a lower element α which are arranged horizontally in two stages, upper and lower, with a predetermined interval of about several tens of millimeters apart. On the other hand, fan (2) consists of, for example, two units. A sirocco-shaped fan is connected to a double-shaft motor to form a multi-base type, and the blowing portion is provided facing the blowing outlet 0υ.

The upper and lower elements (2) and alpha turbidity are illustrated in FIGS. 3 to 8, and are made by alternately and repeatedly laminating flat paper and corrugated paper using porous water-absorbing paper as a material. The upper element (2) has a structure in which a corrugated material having parallel channels in multiple rows and stages is cut into a predetermined cubic shape.
is an upright cubic shape with a left and right width of 330 mm, a front and rear depth of 1351 mm, and a top and bottom thickness of 20 mm. It is formed to have an inclined narrow passage that intersects at an acute angle with respect to the flow direction, for example, at an angle of 75'' with respect to the upper and lower surfaces.

On the other hand, the lower element α3) has a five-sided cubic shape in which the vertical cross section in the front and back direction forms a middle shape, as shown in FIGS. It is formed to have a thickness of 50 mm and a minimum thickness of 40 m at both ends, and has a structure with an inclined bottom where the central part in the front-rear direction is the lowest level.

This lower stage element α3) is formed so that each of the narrow passages is parallel to the thickness direction.

However, when the lower element 0 is installed at a predetermined location inside the casing (1), there is a slight downward slope toward one side in the left-right direction, for example, toward the left side where the pressure vessel (5) is provided. The structure is tilted so that the central part on the left side is the lowest level bottom part. Next, the spray nozzle (4) is formed into a chip shape and has a structure that can be diffused at an acute angle. Above the center of the side,
And the entire lower surface of the upper element (2) and the lower element 03 are provided at a position intermediate between the two elements (2) and 01, and the entire lower surface of the upper element (2) and the lower element 03 are directed toward the gap existing between the two elements (2) and 01.
) is provided so that the liquid can be uniformly sprayed over the entire upper surface.

On the other hand, the pressure container (5) is a cylindrical container with a small volume of about 500 m#, which is generally called an aerosol, and has an on-off valve 04) having a spring-loaded push rod-shaped operation part at the nozzle part.
are directly connected to each other, and the valve is opened by pushing the push rod against the spring force, so that the contained liquid can be spouted from the nozzle port.

The pressure vessel (5) is filled with a deodorizing liquid mainly composed of vegetable essential oil and liquefied gas as a propellant, such as liquefied petroleum gas (? & liquefied propane gas), and the on-off valve Oa is opened. When the liquefied gas in the container evaporates and vaporizes, the deodorizing liquid in the container is pumped as a result of the high pressure rise (3 to 4 kg/cfA). It is ejected from the nozzle.

This pressure vessel (5) has the above-mentioned on-off valve (5) in the machine room on the left side, which is separated from the air flow path by a partition member (QS).
The on-off valve Oa and the spray nozzle (4) are connected to each other by a liquid feeding pipe (6) such as a small diameter vinyl resin tube. The connection is made, thus the pressure vessel (5
After the deodorizing liquid in ) flows through the liquid sending pipe (6) from the nozzle part, it is sprayed as fine liquid particles from the spray nozzle (4).

Next, a switching device (7) is installed in the machine room in association with the pressure vessel (5), and this switching device (7)
An opening/closing lever Oe whose middle part is connected to the spring-loaded push rod of the opening/closing valve Q41 and whose end is pivotally supported, and a plunger is connected to the other end of this opening/closing lever Q[fl through a spring. When the electromagnetic solenoid αη is excited, the plunger is attracted by magnetic attraction, so that the other end of the opening/closing lever aψ is pulled up and the push rod of the opening/closing valve 00 is pushed in. As a result, the on-off valve α is opened.

The structure of the deodorizer is as described above, and in the figure (9)
00 is a remote control device used to operate and scrape at a location distant from the main body, and 00 is a microsinch that transmits different signals depending on whether the pressure vessel (5) is fixed at a predetermined position.

Next, the operation of this deodorizing machine will be explained.

When a driving command is sent by the remote control device (9),
A pulse output is periodically sent to the electromagnetic solenoid αη according to a command from the control board (8).

The opening/closing lever 00 is pulled up by the excitation of the electromagnetic solenoid aη, and the opening/closing valve 04) is opened during this time, whereby the pressurized deodorizing liquid is sent out from the pressure vessel (5) and sent to the liquid feeding pipe (6). is sprayed from the spray nozzle (4), and the upper and lower stage elements Q2) and (13) are impregnated with the deodorizing liquid.

On the other hand, when the fan (2) is driven, the air to be treated is sucked in from the suction port 0ω, flows upward, and is blown out from the blowout port OD, during which time it passes through the deodorizing filter (3) impregnated with the deodorizing liquid. At this time, the odor component comes into contact with the deodorizing liquid agent, reacts, and is removed.

In this case, the control board (8) can easily adjust and control the amount of air blown and the amount of deodorizing liquid to be sprayed in conjunction with each other. There is a pulse interval control method that automatically controls the pulse interval for the pulse output given to the electromagnetic solenoid aη at a predetermined pulse interval so that it is short when the air flow is high and long when it is low.
It is also possible to apply the Hals width control method, which controls the pulse width for the pulse output given to η to be wide when the airflow is large and narrow when the airflow is small. It is possible to increase or decrease the amount of spray per unit time depending on whether the amount of malodorous components is large or small.

By the way, as mentioned above, each narrow passage intersects the air flow direction at an acute angle.
There is almost no increase in air flow resistance, and the particles of the sprayed liquid are not directly accompanied by the airflow, but instead collide and adhere to the walls of the narrow passage, thus preventing the sprayed particles from leaving the deodorizing filter (3). Scattering can be suppressed.

In addition, since the lower element α3) has a lowest level point on the bottom surface, the residual liquid, which is the saturated impregnating liquid, can be concentrated at that point and the droplet point can be defined, and the life of the filter can be predicted.

Moreover, since this lowest level point is directly below the spray nozzle (4), it can be said to be the optimum point in that the wet state due to the liquid that tends to drip each time the nozzle is turned on and off can be quickly detected.

Furthermore, by adjusting the amount of liquid sprayed per unit time in accordance with the amount of air blown by the fan (2), it is possible to replenish the liquid without excess or deficiency in accordance with the degree of lη staining.

However, as the pressure vessel (5), it is possible to use a slightly improved version of a commercially available atomizer called an aerosol, in which the nozzle of the nozzle is removed and only a push button-shaped on-off valve is inserted in the nozzle. At the same time, by removing the liquid introduction tube connected to the inlet of the on-off valve α, it is possible to perform the hydraulic pressure method in an inverted position. The tube can be set to a length that can be reached with plenty of room at the bottom of the container, and can be used even if the liquid inlet is wide. It is possible to smoothly eject liquid,
It's extremely convenient. An example of this structure is shown in FIG.

(Effects of the Invention) The effects of the present invention having the above-mentioned configuration are as follows.

(a) Since the deodorizing filter (3) is arranged in two stages above and below against the rising air flow, and the deodorizing liquid agent is sprayed from the spray nozzle (4) toward the space in the middle, It is possible to uniformly spray the liquid onto the filter while minimizing leakage to the outside of the filter.

(b) Furthermore, unlike the method of dropping from above, this method sprays the liquid in the middle, so the amount of liquid scattered by the flowing air is small and there is almost no risk of increasing the humidity of the processing air.

Moreover, by configuring each narrow passage in the upper element 0 powder to intersect with the air flow direction at an acute angle, scattering of the liquid can be further suppressed.

(c) On the other hand, by providing the lowest level point on the bottom of the lower element α and aligning it with the position directly below the spray nozzle (4), the residual liquid can be concentrated in one place and the dripping point of the liquid can be controlled. At the same time, it is useful in accurately detecting the performance life of the filter.

(d) Since the pressure vessel (5) is placed upside down and the liquid is ejected from below, it can be used without leaving even the last drop, and the amount of loss can be reduced.

(n) Also, since the on-off valve Oa is directly connected and integrated with the pressure vessel (5), high pressure management can be done only with the cylinder-shaped pressure vessel, and pressure management is not required for the liquid feeding pipe (6). Therefore, it is possible to achieve high safety and low cost equipment, and at the same time simplify management.

(f) A fan that adjusts tA according to the degree of malodorous components contained (
Depending on the air volume of 2), the liquid spray interval or 1
By varying the amount of spray per spray, it becomes possible to supply liquid with no excess or deficiency, maintain high deodorizing efficiency, and eliminate the inconvenience of moistening the treated air with the spray liquid.
