On the other hand, the chemical liquid 10 sprayed and dropped from the spray nozzle 15 flows through the upper and lower through holes 17 of the uppermost horizontal flow straightening plate 16 and flows down to the horizontal flow straightening plate 16 therebelow, but as shown in FIG. Since the gas blows up where it falls through the narrow through hole 17, the offensive odor component of the gas (the offensive odor component is said to be solid) is often dissolved in the chemical liquid 10, and the chemical liquid 10 is mainly wood vinegar oil. , Deodorize considerably. The gas deodorized (primarily deodorized) in this way is discharged from an exhaust port 19 formed at the upper end of the chemical deodorization tower 8. Since the chemical liquid 10 becomes a harmless waste liquid having a pH value of about 7 due to the continuous deodorizing action, the drain pipe 2
It is discarded in the waste storage relay tank 1 via 0. Therefore, a secondary treatment facility for the waste liquid of the chemical liquid 10 is unnecessary.

Fix it. Reference numeral 36 denotes a cylinder which is fixed to a bracket 37 fixed to the outer case 26 side, and one of three arms 35 is locked to a piston 38 of the cylinder 36. The tip ends of the arms 35 are connected to each other by a connecting rod 39, and when one arm 35 is rotated by expanding and contracting the piston 38 of the cylinder 36, the other arms 35 are also rotated in association with each other. The three rotation shafts 33 are configured to rotate simultaneously.

When the rotary shafts 33 are rotated counterclockwise in FIG. 8, the net shelves 31 are tilted so that the adsorbing / deodorizing material 28 deposited on the net shelves 31 can be dropped downward. In the actual replacement work, first, the lower cylinder 36 is operated to drop the adsorbing / deodorizing material 28 deposited on the lower rack 27 onto the bottom portion 40 of the outer case 26, and then the lower rack 27 is used as a base. After returning, the upper cylinder 36 is operated to drop the adsorbed deodorizing material 28 deposited on the upper rack 27 onto the lower rack 27 and deposit it. After returning this to the upper rack 27, the new adsorption / deodorizing material 28 is passed through the window through hole 41 in the upper part of the outer case 26.
To supply. The adsorptive deodorant material 28 dropped on the bottom portion 40 is taken out from the take-out port 42.

Engaging members 43 are provided on both the left and right sides of each net rack 31 and inside the outer case 26 so that the slanted net racks 31 can be correctly returned to the horizontal row as shown in FIG. It is attached so that it does not rotate to the right from the position shown in FIG. 44 is the exhaust port 3 of the chemical deodorizing tower 24.
It is a stack connected to 0.

FIG. 10 shows a connecting portion between the suction pipe 4 of the suction fan 3 and the waste storage relay tank 1, which is normally the suction pipe 4.
Is connected vertically to the waste storage relay tank 1, but if it is left as it is, the pests generated in the waste storage relay tank 1 may crawl up inside the suction pipe 4, and pests may be generated in unexpected places. .. Therefore, in the present application, the iron pipe 45 is provided at the connection portion between the suction pipe 4 and the waste storage relay tank 1, and the heating element 46 is wound around the outer circumference of the iron pipe 45 to heat the iron pipe 45, whereby the iron pipe 45 is heated. It is constructed so that no pests will climb up from 45 to the upper part.

The human waste collected in the waste storage relay tank 1 is collected by the large vacuum car 47. At this time, a large amount of odorous gas is emitted from the exhaust pipe 48 of the vacuum car 47, which causes environmental problems. May be. Therefore, in the present invention, the branch pipe 49 is branched from the suction pipe 4 of the suction fan 3 through the valve 53, and the branch pipe 49
The flexible swing arm tube 50 is attached to the tip of the swing arm tube 50, and the vacuum car 4 is attached to the tip of the swing arm tube 50.
Hood-shaped cap 51 that fits snugly into the exhaust stack 48 of 7.
When collecting the human waste by the vacuum car 47, the cap 51 is put on the exhaust pipe 48, and the exhaust pipe 48 is attached.
All the odorous gas discharged from the suction fan 3 is sucked through the branch pipe 49.

In the above, the above-mentioned facilities are housed in one house 52, and the vacuum car 47 for collecting human waste stored in the waste storage relay tank 1 also has a house 52 through the gate.
The human waste in the waste storage relay tank 1 is pumped out in the state of being put inside.

[0018]

The human waste collected from ordinary households, public toilets, hotels, etc. by the small vacuum car is temporarily stored in the waste storage tank 1 and is collected by the large vacuum car 47 at any time and conveyed to the human waste treatment facility. The odorous gas generated during the temporary storage is constantly sucked by the suction fan 3 via the suction pipe 4, and is sent to the chemical deodorization tower 8 of the chemical cleaning device 7 through the exhaust pipe 6. In the chemical liquid deodorizing tower 8, the odorous gas rises from the lower inlet port 18 toward the upper outlet port 19 through the through holes 17 of the plurality of horizontal rectifying plates 16, while the upper spray nozzle 15 discharges the odorous gas. Chemical liquid 1 circulated by pump 11
0 is sprayed downward, and as shown in FIG. 4, the gas blows up where the drug solution 10 falls through the narrow through hole 17, so that the offensive odor component of the gas is often dissolved in the drug solution 10, Is mainly wood vinegar oil, so it deodorizes considerably.

Since the chemical liquid 10 becomes a harmless waste liquid having a pH value of about 7 due to the continuous deodorizing action, the drain pipe 20
It is disposed of in the waste storage relay tank 1 via. Therefore, a secondary treatment facility for the waste liquid of the chemical liquid 10 is unnecessary. The gas thus deodorized by the chemical solution reaches the mist separator 22 from the exhaust port 19 through the communication pipe 21, where the residual water (chemical solution 10) in the gas is separated, and the gas content is It is sent to the chemical deodorizing tower 24 via the connecting pipe 23. In the chemical deodorization tower 24, gas enters from an inlet 29 at a lower position and rises inside the outer case 26 of the chemical deodorization tower 24 to raise the rack 27.
After being deodorized by the adsorbing and deodorizing material 28 deposited on, the air is exhausted from the exhaust port 30 in the upper part.

When the adsorbing deodorizing material 28 of the chemical deodorizing tower 24 is deteriorated (when the odor concentration from the exhaust port 30 exceeds a predetermined value or when a predetermined working time is exceeded), first,
The cylinder 36 of the lower rack 27 is operated to rotate the three arms 35 connected to each other by the connecting rod 39,
As a result, the three rotary shafts 33 fixed to the arm 35 are rotated counterclockwise in FIG. 8 to incline the three net shelves 31 of the lower rack 27, and the adsorption and deodorizing material 28 in the lower stage is placed in the outer case from the gap created by the inclination. It is dropped to the bottom portion 40 of 26, taken out from the outlet 42, the cylinder 36 is returned, and the three net shelves 31 of the lower rack 27 are returned horizontally.

Then, by the same operation, the adsorbing deodorant material 28 of the upper rack 27 is dropped, and the lower rack 27 is dropped.
In the upper rack 27, which has been accumulated and then returned to the horizontal position, a new adsorption deodorizing material 2 is introduced from the window through hole 41 in the upper part of the outer case 26.
8 is supplied to fill and deposit. As a result, the adsorbed deodorizing material 28 in the chemical deodorizing tower 24 is deposited with the deteriorated adsorbing deodorizing material 28 in order from the bottom. Adsorption deodorant 2
Replacing 8 makes it extremely easy to use used deodorant material 28
Only can be exchanged.

The human waste that has been temporarily stored in the waste storage relay tank 1 is collected by placing a large vacuum car 47 in the house 52. At this time, a hood-like cap 51 provided at the tip of the swing arm pipe 50 is completely fitted into the exhaust pipe 48 of the vacuum car 47, and a large amount of odorous gas emitted from the exhaust pipe 48 is sucked through the branch pipe 49. It is sucked by the fan 3. As a result, no odorous gas leaks to the outside when collecting human waste by the large vacuum car 47, and the environment can be kept good.
