Description

  The present invention relates to a deodorizing apparatus for deodorizing odorous gas containing a large amount of ammonia generated in garbage disposal, human waste treatment, animal dung treatment such as chicken dung, or sludge treatment.

  A first treatment tank in which an odor gas containing a large amount of ammonia is brought into contact with the spray water, and a water-contacted odor gas from the first treatment tank and a sulfuric acid spray solution are brought into contact with each other to mainly neutralize ammonia in the odor gas. 2 treatment tanks, a third treatment tank in which the acid contact odor gas containing sulfuric acid mist from the second treatment tank is brought into contact with the spray water to remove sulfuric acid into the spray water, and the odor gas from the third treatment tank is passed through. There is known a deodorizing apparatus including a fourth treatment tank that adsorbs and removes odorous components on activated carbon and discharges deodorized gas (for example, Patent Document 1).

JP-A-2004-130163 (FIG. 4) nothing special

Since the above-mentioned conventional technology is to remove the sulfuric acid from the sprayed water by bringing the acid contact odor gas containing sulfuric acid mist into contact with the sprayed water in the third treatment tank, a sufficient deodorizing process can be obtained because it remains in the neutralization process. Therefore, the final deodorization with activated carbon had to be performed after that.
Therefore, since the final deodorizing treatment is performed with the adsorption layer of activated carbon, the apparatus is expensive, and the processing cost is high for replacing the activated carbon.
Further, in the first treatment tank and the third treatment tank, water is stored in the tank, and this water is circulated and sprayed. A valve is provided at the discharge part of the tank, and this valve is appropriately set. Since it is configured to open and discharge to the outside of the tank, there is a drawback that the cost of the valve parts, the pH sensor, the valve automatic control device, etc. is high for automatic discharge.

  An object of the present invention is to provide a deodorizing apparatus that effectively achieves deodorization without performing a final deodorizing process using activated carbon or the like in view of the above-described drawbacks of the conventional technology.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.

Then, the second treatment agent 27 is charged until the pH value of the second treatment agent 27 reaches about pH 2-3.

The injection of the second treatment agent from the acid solution spray nozzle 30 may be a high-speed spray, and the acid solution spray nozzle 30 may be rotated by the spray force, or the pipe support 29 may be rotated by a motor.
Further, high-speed injection of the second processing agent from the acid solution spray nozzle 30 is also violently collided with the side wall of the processing tank body 25, the partition plate 26, preferably the top plate, so that odor substances such as slime do not adhere to the wall. Or it should be washed off. In this case, the duct 49 is preferably extended upward.
When the second treatment agent is sprayed, the filtration filter part 32 may not be provided, and the acid solution storage part 28 is preferably separated from the second treatment tank 3 and communicated with the spraying device. .

As shown in FIGS. 1 and 2, the stabilized acid spraying device 52 is introduced in a state where the stabilized acid sprayed 53 is mixed with the acid-contacted odor gas 36 before being put into the processing tank body 50, and the processing tank. When entering the main body 50, many enter in an active acid state. However, in addition to such a form, there are various forms such as injecting without mixing with the acid-contacted odor gas 36 from the side wall, injecting from above and discharging downward.
The concentration of the sprayed stabilized acid 53 is 500 ppm in the experimental apparatus, but is not limited to this concentration. In addition, an odor sensor is provided in the duct 49, and the amount and concentration of the sprayed stabilized acid 53 are automatically adjusted based on the sensing information of the odor sensor. This is preferable because the waste of the processed product 53 is reduced, the stable deodorizing ability without any variation is always maintained, and the amount of the sprayed stabilized acid can be minimized.

Stabilized chlorine dioxide oxidizes and deodorizes odorous gas components by the oxidizing power of oxygen atoms, and acts as an antiseptic by preventing decay.
Sodium chlorate / sodium perchlorate / salach powder / sodium hypochlorite are all deodorized by chloride ions. For this reason, if there is an organic substance in water or the like, a chlorine compound having a concern of carcinogenic substances such as trihalomethane is by-produced. However, in the case of stabilized chlorine dioxide, it is a deodorization due to the oxidizing power of oxygen atoms, and therefore, no harmful chlorine compound such as trihalomethane is produced like a chlorinating agent.

In the case where the detection of the odor concentration of the acid-contacted odor gas 36 by the odor sensor 62 is a concentration that cannot be applied by the amount of spray of the stabilized acid sprayed by the stabilized acid spray device 52, the high concentration spray mode is set. Thus, a high concentration value is automatically set, a high concentration of stabilizing acid is supplied from the stabilizing acid input unit 61, and it is supplied until the concentration sensor 48 detects the set high concentration value, and is then automatically adjusted to obtain a high concentration. The stabilized acid is sprayed to be sprayed.
