Embodiment 1

[0039] refer to figure 1 with figure 2 ,Such as figure 1 As shown, the photocatalyst-ClO in this example 2 The combined deodorization device includes an isolation net 1 and a spray device 2, and is used in open environments such as livestock and poultry houses and septic tanks. The isolation net 1 is arranged around the livestock and poultry house and / or septic tank, and the isolation net 1 is loaded with a photocatalyst for degrading the malodorous substance in the air, and the spray device 2 sprays through the spray nozzle 21 arranged on the isolation net 1 ClO 2 disinfectant. Such as figure 2 As shown, in the present embodiment, the spray device 2 includes a spray nozzle 21, a water pump 22, a water tank 23 and a spray electric control box 24, and the spray nozzle 21 is located above the isolation net 1; the spray nozzle 21 passes through the water pump 22 is connected to said water tank 23; Said water tank 23 is used for containing ClO 2 Disinfectant; the spray el...

Embodiment 2

[0043] Such as image 3 As shown, different from Example 1, the photocatalyst-ClO provided by this example 2 The combined deodorizing device also includes a thermo-hygrometer 25 and a filter 26 . The thermo-hygrometer 25 is electrically connected with the spray electric control box 24 for detecting the temperature and humidity in the open environment, and feedbacks the detection result to the spray electric control box 24. Described filter 26 is connected between water pump 23 and tank 24, is used for filtering ClO 2 Disinfectant so that the requirements for fine mist spraying can be met.

[0044] In the present embodiment, on the isolation net 1, be coated with by CT catalyst (20g / m 2 ) and nano-TiO2 catalyst (20g / m 2 ) composed of a combined catalyst, the temperature of the pig house is 22-28°C. Spray and disinfect the piggery every 76 hours, ClO 2 (Chlorine dioxide) concentration is 20ppm, every 10 minutes. After 12 days of testing, the stench of the experimental pig...

Embodiment 3

[0046] Different from Example 2, in the present example, the isolation net 1 is coated with CT catalyst (30g / m 2 ) and nano iron oxide (20g / m 2 ) composed of a combined catalyst, the temperature of the pig house is 22-28°C. Spray and disinfect the piggery every 36 hours, ClO 2 (Chlorine dioxide) concentration is 100ppm, every 60 minutes. After 12 days of testing, the stench of the experimental pig house has been greatly improved. Control group does not use photocatalyst-ClO of the present invention 2 Combined deodorization device, control group NH 3 The average concentration is 13.49mg / m 3 , H 2 The average concentration of S is 9.55mg / m 3 . The average concentration of NH3 in the experimental group was 3.04mg / m 3 , H 2 The average concentration of S is 4.38mg / m 3 .

Abstract

The invention discloses a combined photocatalyst-ClO2 deodorization device which comprises an isolation net and a spraying device, wherein the isolation net is arranged at the periphery of a deodorization space and is loaded with a photocatalyst; the photocatalyst is used for degrading odorous substances in air; the spraying device is used for spraying ClO2 disinfection liquid to the deodorization space. The invention further discloses a deodorization method adopting the deodorization device. The deodorization device can be directly used in the periphery of an animal building and / or a manure pit, is capable of timely treating odor in an odor place and directly disinfecting and deodorizing an open environment without collecting the odor, and so that the odor removing is relatively convenient; in addition, sunlight is taken as a light source, the odorous substances in the air are degraded by adopting the photocatalyst under the condition of visible light irradiation, an ultraviolet light source does not need to be arranged, the odor can be relatively safely removed, and the deodorization cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of odor comprehensive treatment, in particular to a photocatalyst-ClO 2 Combined deodorization device and deodorization method. Background technique [0002] Odor in farms is a difficult and hot spot in the pollution control of farms. The malodorous gas in the farm will cause the immunity of livestock and poultry to decline, affect the growth of livestock and poultry, and interfere with the sense of smell of nearby residents, often causing residents to complain and protest, directly restricting the development of my country's ecological animal husbandry. For example, in pig farms, according to statistics, every 10,000 pig farms emit an average of 15.9kg of NH per hour to the atmosphere. 3 , 1.45kgH 2 S and 2.59kg feed dust. Taking ammonia as an example, studies have found that when the volume fraction of ammonia in the air in the living environment of young pigs reaches 0.005%, the weight gain rate of yo...
