DETAILED DESCRIPTION

[0015] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0016] As Figure 1As shown, a kind of deodorization absorption tower device containing particulate matter includes odor treatment unit, and the odor treatment unit includes primary gas-liquid separation chamber, secondary dust removal chamber and tertiary high-efficiency absorption chamber, primary gas-liquid separation, secondary dust removal treatment and tertiary high-efficiency absorption all have respective advantages, first mist dehydration zone is sequentially arranged in the first gas inlet area of primary gas-liquid separation chamber from bottom to top, the first gas inlet passage 1 for being used to pass into odor is arranged in the gas inlet area of primary gas-liquid separation chamber, the top of the secondary dust removal chamber and the gas inlet area of the tertiary high-efficiency absorption chamber are provided with the second gas inlet passage 3, the third gas inlet passage 5 is arranged between the top of the secondary dust removal chamber and the gas inlet area of the tertiary high-efficiency absorption chamber, the liquid storage area of the tertiary high-efficiency absorption chamber and corresponding spray head are provided with the spray channel 6 and the circulating spray pump 7, the first drainage channel 8 is arranged on the spray pipeline of the tertiary absorption chamber, and the top of the tertiary high-efficiency absorption chamber is provided with the exhaust passage 9.

[0017] The first mist dehydration zone 2 of the primary gas-liquid separation chamber and the filler area 10 of the tertiary high-efficiency absorption chamber are both composed of a bower ring, the dust removal area 4 of the secondary dust removal chamber is composed of non-woven fabric, which is low in price and high in dust removal efficiency, and the treatment efficiency of the particulate odor is gradually improved by the three-stage treatment.

[0018] The liquid level gauge 12 is arranged in the liquid storage area of the tertiary high-efficiency absorption chamber, for detecting the liquid level of the liquid storage area of the tertiary high-efficiency absorption chamber.

[0019] The liquid delivery channel 13 is arranged in the liquid storage area of the tertiary high-efficiency absorption chamber, for delivering nutrient liquid to the third gas inlet area, and the PH meter 14 is arranged in the liquid storage area of the tertiary high-efficiency absorption chamber, for detecting the PH value of the liquid storage area of the primary absorption chamber.

[0020] As shown in the drawings, Figure 1 The deodorization method of the deodorization absorption tower device containing particulate matter of the utility model is as follows:

[0021] (1) odor first enters the first gas inlet area 15 by the first gas inlet passage 1, passes through the first mist dehydration zone 2 of the primary gas-liquid separation chamber, separates the gas containing particulate odor and liquid, and the separated liquid is discharged through the second drainage channel 16, and then the dehydrated odor enters the dust removal area 4 in the secondary dust removal chamber through the second gas inlet passage 3. The dust removal efficiency is high, and can reach more than 98%.

[0022] (2) The third inlet 5 is used to let the dust-removed odor enter the third high-efficiency absorption chamber, and the spray liquid in the third high-efficiency absorption chamber is mixed with the source water and the nutrient liquid, for example, the ratio of sodium hydroxide to water is about 1:8, the source water enters the liquid storage area of the third high-efficiency absorption chamber through the water inlet channel 17, and the nutrient liquid enters the liquid storage area through the liquid inlet channel 13, and when the PH of the mixed liquid reaches 10.5-11.5 and the liquid level reaches the corresponding value, the second electromagnetic valve 22 and the third electromagnetic valve 18 are closed.

[0023] (3) The dust-removed odor enters the filler area 10 through the third inlet channel 5, the circulating spray pump 7 of the third high-efficiency absorption chamber is opened, the spray liquid is sprayed to the filler area 10 through the spray channel 6 and the spray head 19, the odor is uniformly dispersed by the Pall ring in the filler area, the spray liquid is sprayed downward to absorb the substances in the odor that can be dissolved in water and react with the nutrient liquid, and the purified odor passes through the second demisting and dewatering area 11, the water mist is gathered into large water droplets when passing through the Pall ring and falls down, so that the water mist in the gas is intercepted, and the dewatered purified gas is discharged through the exhaust channel 9.

[0024] (4) Since the spray liquid can be circulated and sprayed in the third high-efficiency absorption chamber, the spray liquid continuously absorbs the dust-removed odor, the hydrogen sulfide, citric acid and other acidic gases, and the PH value of the spray liquid gradually decreases, when the PH meter 14 detects that the PH of the spray liquid in the liquid storage area 20 of the third high-efficiency absorption chamber is lower than 3.5, the first electromagnetic valve 21 is opened, the acidic spray liquid is discharged from the third high-efficiency absorption chamber, and at the same time, the liquid storage area 20 in the third high-efficiency absorption chamber is again supplemented with source water through the water inlet channel 17 and with nutrient liquid through the liquid inlet channel 13, and the liquid supply is stopped until the liquid level meter PH value reaches the required value, so that the circulation and spray absorption of the odor are performed again, and this method can cope with relatively severe load impact.

[0025] (5) The liquid level meter 12 is arranged in the liquid storage area 20 in the third high-efficiency absorption chamber. When the liquid storage area 20 reaches the high liquid level, the first electromagnetic valve 21 is started to discharge the excess liquid.

[0026] In the process of treating the odor containing particulate matter, when the hydrogen sulfide inlet concentration is about 180 mg / m 3 , the outlet concentration can reach 1.3 mg / m 3The removal rate is more than 99%; when facing the odor containing particles, the method can cope with larger impact load and effectively remove the odor. In the traditional biological deodorization process, when the concentration is high, the fan and related equipment facilities need to be increased to dilute the odor, and then the odor can be treated to meet the emission requirements. The process utilizes the three-stage treatment of gas-liquid separation, dust removal and absorption to purify the odor, the method has high empty tower rate, rapid reaction, fast absorption, high treatment efficiency for the odor containing particles, at the same time, the integrated device is simple and convenient to operate, convenient for later operation and maintenance, small in occupied area, and greatly saves the occupied area.

[0027] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
