Description

Technical Field

[0001] This application belongs to the field of negative pressure deodorization technology, and more specifically it relates to a negative pressure deodorization and dust reduction machine box for livestock farms with good purification effect. Background Technology

[0002] Aquaculture refers to the production activities of cultivating and reproducing plants and animals through artificial intervention, covering types such as livestock, poultry, aquatic products and special breeding. Qin Mu once described the breeding process of chrysanthemums and goldfish, and Xu Chi mentioned the aquaculture scene. In order to protect the environment, it is necessary to purify the odor in the breeding area of ​​the breeding farm.

[0003] Currently, Chinese patent CN222969541U discloses a deodorizing and dust-reducing device, including an outer cover, an air inlet on the side wall of the outer cover, an air outlet on the top of the outer cover, a deodorizing water curtain between the air inlet and the air outlet and the deodorizing water curtain completely blocking the air outlet, a water outlet between the deodorizing water curtain and the air inlet, and a water spraying component between the deodorizing water curtain and the air outlet, with several water spray holes on the water spraying component.

[0004] Existing deodorization and dust suppression devices similar to those described above only use spraying for deodorization, which cannot completely remove odors and has a poor purification effect, thus leaving room for improvement. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a negative pressure deodorization and dust reduction machine box for farms with good purification effect. Its advantage is that it has a good deodorization effect and avoids odor pollution to the surrounding environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure deodorization and dust reduction chamber for livestock farms with good purification effect, comprising a base, a purification chamber on the top of the base, a fan interface on one side of the purification chamber, a sealing cloth on the end of the fan interface away from the purification chamber, the fan interface being connected to a livestock farm fan through the sealing cloth, a fixing component inside the purification chamber, a UV catalytic group, an atomizing unit, and three gas phase filler groups respectively arranged on the inner wall of the fixing component, the atomizing unit being close to the fan interface, two gas phase filler groups being arranged between the atomizing unit and the UV catalytic group, and the other gas phase filler group being located on the side of the UV catalytic group away from the atomizing unit.

[0007] By adopting the above technical solution, the farm's blower extracts odorous gas from the farming area and connects it to the deodorizing blower outlet via a sealing cloth. The odorous gas passes through the deodorizing blower outlet to the atomizing unit, where it is sprayed with atomized deodorizing liquid for initial deodorization. The odorous gas mixes with the deodorizing water mist and then passes through two gas-phase packing groups, where dust suppression and deodorization are basically completed. Between the second and third dust suppression groups, there is a UV catalytic group, which mainly catalyzes the decomposition of the deodorizing liquid, making its deodorization effect more thorough. After passing through the third dust suppression group, the deodorization ends, resulting in a good deodorization effect and preventing odor from polluting the surrounding environment.

[0008] In a preferred embodiment: the purification chamber includes a bottom water curtain, side water curtains are provided on both sides of the bottom water curtain, a back water curtain is provided on the back of the bottom water curtain, and a top water curtain is provided on the top of the side water curtains.

[0009] By adopting the above technical solution, the installation of 5 water curtains can reduce wind resistance and maintain a basic balance between the air pressure and wind speed at the outlet of the negative pressure fan.

[0010] In a preferred embodiment, the gaseous packing assembly has a three-dimensional mesh structure.

[0011] By adopting the above technical solution, the design of the three-dimensional mesh structure can increase the contact area and time between odor and chlorine dioxide spray, prolong the reaction process, and at the same time adsorb some odor molecules that are not oxidized in time, thus greatly improving the deodorization coverage and efficiency.

[0012] In a preferred embodiment: the interior of the gaseous packing assembly is provided with nano-sized fumed silica.

[0013] By adopting the above technical solution, the setting of nano-sized fumed silica can avoid particle agglomeration, and there is no sedimentation within 1 hour after atomization, improving the dispersion stability by more than 50%.

[0014] In a preferred embodiment: the UV catalytic group is a photocatalytic UV lamp, and the wavelength of the photocatalytic UV lamp is 254 mm.

[0015] By adopting the above technical solution, when chlorine dioxide is irradiated by 254mm photocatalysis, its molecules will be instantly activated and transformed into high-energy free radicals such as ・ClO2 and ・OH. The oxidation capacity of these "chemical cleaners" far exceeds that of ordinary chlorine dioxide, enabling a qualitative leap in deodorization speed and effect.

[0016] In a preferred embodiment: the atomizing unit includes an annular spray pipe, and the inner wall of the annular spray pipe is provided with a plurality of atomizing nozzles distributed at equal intervals.

[0017] By adopting the above technical solution and setting the atomizing nozzle, multi-directional spraying can be achieved, which improves the deodorizing effect of the spray.

[0018] In a preferred embodiment, the fastener is made of stainless steel.

[0019] By adopting the above technical solution, the fasteners made of stainless steel have good corrosion resistance and improve their service life.

[0020] Compared with the prior art, this application has the following beneficial effects: 1. The farm's ventilation fan extracts odorous gases from the farming area. The odorous gases are connected to the deodorizing fan outlet via a sealing cloth. The gases pass through the deodorizing fan outlet to the atomizing unit, where atomized deodorizing liquid is sprayed out for initial deodorization. The odorous gases mix with the deodorizing water mist and then pass through two gas-phase packing groups, completing the basic dust suppression and deodorization process. Between the second and third dust suppression groups is a UV catalytic group, which mainly catalyzes the decomposition of the deodorizing liquid, making the deodorization effect more thorough. After passing through the third dust suppression group, the deodorization process ends, resulting in good deodorization and preventing odor pollution of the surrounding environment. 2. The installation of 5 water curtains reduces wind resistance and maintains a basic balance between air pressure and air velocity at the outlet of the negative pressure fan. The three-dimensional mesh structure of the gas phase packing increases the contact area and time between odor and chlorine dioxide spray, prolonging the reaction process. At the same time, it can adsorb some odor molecules that are not oxidized in time, greatly improving the deodorization coverage and efficiency. 3. When chlorine dioxide is irradiated by 254mm photocatalysis, its molecules are instantly activated and transformed into high-energy free radicals such as ·ClO2 and ·OH. The oxidation capacity of these "chemical cleaners" far exceeds that of ordinary chlorine dioxide, resulting in a qualitative leap in deodorization speed and effect. Nanoscale fumed silica can prevent particle agglomeration, and there is no sedimentation within 1 hour after atomization, improving dispersion stability by more than 50%. Attached Figure Description
