Description

DETAILED DESCRIPTION OF THE INVENTION The present invention particularly relates to a method and apparatus for deodorizing strong odors such as excrement and urine.

This invention is not limited to deodorizing odors caused by mushroom urine, but is applicable to all kinds of odors.

The purpose of this invention is to significantly improve the odor deodorizing function and to use the deodorizing agent efficiently.

In a conventionally known method of this type, activated carbon is generally placed in a container, the odor is passed through the activated carbon layer, and a deodorizing reaction is generated during the short passage time, thereby deodorizing.

Therefore, if the deodorizing function is to be effective, a large amount of activated carbon is required and the container has to be large. Moreover, since the activated carbon is left still, there is no contact with passing odors.
The fii product is small, the reaction is not sufficient, and the activated carbon cannot be used effectively. Various inventions and ideas have been made for recycling and effective use, but the reality is that they require separate equipment and are becoming more complex.

This invention aims to eliminate the above-mentioned drawbacks, and its gist is to remove odors that have been preliminarily deodorized and dehydrated into a fine deodorizer made of scattered powder or a deodorizer made of minute particles. They are an invention of a method of supplying and deodorizing with a deodorizing agent, and an invention of a device for scattering the deodorizing agent.

In order to further remove the water in the exhaust gas supplied into the cylindrical container 15 and dry the exhaust gas, as shown in FIG. It is preferable to wrap the pipe and further cover the outside of the heating device 43 with a heat insulating material 44 .

In the above embodiment, the rotor 1 is used as a means for scattering the deodorizer.
7, but an example of (III) is given below.

■This example is shown in FIG. 6, in which a rotating shaft 46 is provided at the center of the circular container 45, and a large number of cams 4 are provided on the rotating shaft 46.
7 are arranged in a row, and the deodorizer 27 is scattered by rotating the rotating shaft 46.

(2) This example is shown in FIG. 7, and has a structure in which the deodorizing agent 27 is housed in @1a48 and the deodorizing agent 27 is floated and scattered by vibrating the diaphragm 50 by the vibrator 49.

(14) 0 This example is the same as shown in Fig. 8, and the container 51 is tilted left and right at 180 degrees around the axis, and by intermittently performing this reversal movement, the inside of 'a51 is This configuration prevents the deodorizer 27 from scattering into the container 51.

■This example is shown in FIG.
The deodorizer 27 contained in the container 52 is entrained and deodorized by the pressure of exhaust gas supplied from outside the container 52. Of course, pre-pressure air may be supplied separately from the supply of 411° gas.

6 This example is shown in Figure IQ. (-1) The structure is such that a nearly uniform abrasion 27 is supplied by natural falling from one side.

0 This example is shown in @1111, where the container 54
An electrode plate 55 is provided in the center of the container 5/I so as to be movable from side to side, and another electrode plate 56 is fixed at a spaced interval on both sides of this electrode plate 55. 27 is 11'7
By alternately setting the pole plates 56 on both sides to N or S poles, the central pole plate 55 is attracted and repulsed (15), and the deodorizer 27 is moved left and right into the container 54. It is configured to scatter.

Next, the operation of the present invention will be explained with reference to embodiments.

The foul-smelling exhaust gas released from the exhaust pipe of the vacuum car passes through the BZ pipe 1 of the #4 installation 2 and enters the I+
14 dust is removed, and the exhaust gas from which Il# dust has been removed is sent to the g-order deodorizing device 5 in the next step via the filter element 3. The transferred exhaust gas changes into small bubbles through the pipe 7 having micropores, and is sent into the deodorizing liquid 8 in the device 5. Dissolved on contact with liquid. Since the exhaust gas that has been preliminarily deodorized contains moisture, the next process is carried out using a secondary dehydration system (mt) to remove this moisture.
9 to remove moisture. In this case, if there is a large amount of water, a secondary dehydration device may be further provided for dehydration.

Then, the dehydrated exhaust gas is fed to the second deodorizing example 14 using a fine powder deodorizing agent or a fine particle deodorizing agent (16) at a speed of about 50 cm per second to perform deodorization.

In this case, the rotary wheel 17 in the secondary deodorizing device 14 is rotated at a rotation speed of, for example, 24 OR.P-M, and the AtJ piece 16 scatters the deodorizing agent 27 into the valley +a15.

And since the d-piece 16 has a hollow 21 formed, -
1- The temporarily lifted deodorizer 27 is dropped downward through the through hole 21 without occupying any space in the container 15, and the inside of the container 15 is uniformly distributed. Deodorizer 27
There are 6 phrases. In this way, the deodorizer 27 is heated to 1 m, and the dehydrated exhaust gas is supplied into the tank, and the exhaust gas comes into contact with the scattered deodorizer 27, is reliably deodorized, and is released from the exhaust hole 29. Deodorized gas is exhausted into the atmosphere.

In addition, in this invention, an air cleaner element 22 is provided in the secondary deodorizing device 14, or an odor direction reversible valve device f is provided between the secondary deodorizing device 14 and the primary dehydrating device 9.
l! ! 31, and a secondary deodorizing device 111114 (
17) The operation in the case where the tertiary deodorizing device 141) is also included in a will be explained. In the 21st mother, the exhaust gas is at valve 3
4 is opened and passes through the intake pipe 32, and the secondary deodorizing device 1
(In this case, the valve 36 of the reverse pipe 35 closes the transfer of exhaust gas.) Then, it passes through the air cleaner element 22, and the partition plate 20
Exhaust gas is supplied to the rotor blade 17 side through the through hole 21 . In this case, dust contained in the exhaust gas is trapped by the air cleaner element 22.

Next, the rotation 11Il17 rotated by the rotating shaft 18 raises the dehydrating agent 27 in the container 15 by one inch, and since the inside of the container 15 is filled with the scattered dehydrating agent 27, exhaust gas is supplied to this atmosphere. ,
The exhaust gas comes into contact with the scattered deodorizing agent 27 to cause a deodorizing reaction and perform deodorization. In this case, the exhaust gas is in the container 15
Since the reaction takes place over the entire time that the deodorizer passes through the gas, the reaction time is longer than when the deodorizer is partially left still (18). Since it covers the entire circumferential surface of 27, the contact area for reaction is maximized. The deodorized exhaust gas is then discharged through the exhaust hole 29.
It passes through the through hole 2I formed in the side partition plate 20 and is further transferred to the exhaust hole 29 side via the air cleaner element 22.

In this case, every second】6I! ~22J of exhaust gas at 50c/sec
If it is supplied at a speed of m, it has a deodorizing effect, and the deodorizing agent 27
Although the deodorizing agent 27 is not excessively transferred to the exhaust hole 29 side, if exhaust gas is supplied for a long time, the deodorizing agent 27 in particular will be transferred to the partition plate 20.
The air cleaner element 22 on the through hole 21 or exhaust hole 29 side may become clogged. Therefore, the timer 39 of the odor direction reversible valve device 31, the magnetic switch 3
8 is operated intermittently, the valve 36 of the reversible pipe 35 is opened, and the valve 34 of the intake pipe 32 and the trachea 33 are closed. The gas does not pass through the intake pipe 32,
A discharge pipe passes through one (19) reversible pipe 35 connected to the intake pipe 32 and the exhaust pipe 33, and is further connected to the exhaust hole 29 of the quaternary deodorizing device 14 and the exhaust pipe 33 of the odor direction reversible valve device 31. It passes through the pipe 30, the exhaust hole 29, the air cleaner element 22 on the side of the exhaust hole 29, and the through hole 2 of the partition plate 2 ().
1 into the container 15, passes through the through hole 21 of the partition plate 20 on the intake hole 28 side, the air cleaner element 22, and the other reversible tube 3 of the odor direction reversible valve device M31.
5 and is discharged into the atmosphere from the exit of the exhaust pipe 33.

Therefore, the exhaust gas intermittently reverses and flows back inside the secondary deodorizing device 14, so the deodorizing agent 27 tends to flow toward the exhaust hole 29 side.
is returned to the container 15 by the pressure of the exhaust gas, and the deodorizer 2
The deodorizing agent 27 is never concentrated on one side, and the deodorizing agent 27 is always contained in the container 15 in a uniform state.

Therefore, the deodorizing function is always stabilized.

Next, as shown in FIG. 4, a description will be given of the operation when a tertiary deodorizing device 14b is provided alongside the secondary deodorizing device 14a to deodorize odor.

(20) The operation of this example is basically the same as that of the actual M11 example (see Figure 2), and the exhaust gas supplied from the intake pipe 32 is sent to the container 15 of the tertiary deodorizing device 1M + 4a. It is supplied from the exhaust hole 29 through the communication pipe 42 into the container 15 of the fourth deodorizing device 14b, and then continues to the Fjli
Deodorized exhaust gas is released into the atmosphere through an exhaust pipe 33 connected to the air hole 29. (b) When exhaust gas is supplied from the exhaust hole 29 side of the 10-way secondary deodorizing device +4b, the odor direction reversible valve device 3
This is done by opening the valve 36 of the first reversible pipe 35 and opening and closing the valves 34 of the intake pipe 32 and exhaust pipe 33. In this way, the exhaust gas is conversely supplied from the tertiary deodorizing device 14b to the tertiary deodorizing device 1d 14a via the communication pipe 42,
The exhaust gas passes through one reversible pipe 35 and is released into the atmosphere. In this way, by installing the secondary 1 (tertiary deodorizing device 14a to the G2 odor device 14a) and 4b, the deodorizing function can be further improved, as well as the 4th deodorizing device 14.
The deodorizers in the exhaust gas a and the tertiary deodorizer 114b may be mixed (21) to achieve deodorization depending on the components in the exhaust gas.

Further, it is free to connect a deodorizing device having the same configuration as a fourth deodorizing device to the tertiary deodorizing device 14b.

Since this invention has the above configuration, it has the following effects.

(1) Since the deodorizing agent is dispersed and the exhaust gas is supplied into the atmosphere for deodorizing, the contact area of the deodorizing agent with the exhaust gas can be maximized and the deodorizing effect is extremely large.

(2) If deodorizing is carried out by leaving the deodorizer still, the effective use of the deodorizer is seriously lacking, but in the case of this invention, the deodorizer is used by being dispersed in the air, so the effective usage rate of the deodorizer is extremely high.

(3) Since deodorization is carried out using the smallest possible deodorizer, the device can be made smaller.
