[0050] The thickened double-layer filter material has better filtering effect.

[0051] A demister 27 is provided at the top of the deodorizing filter material.

[0052] Pig houses, including integrated ventilation systems with air filtration.

[0053] According to the air inlet channel, they are: three-proof net 5 - air filtration system 6 - environmental control system - deodorization system 10, which can fully purify the air in the pig house and ensure the health of the pigs.

[0054] The first line of security protection: triple protection net 5.

[0055] There is a lot of rain and mosquitoes in summer. The three-proof net 5 is an important equipment to prevent mosquitoes, birds, and mice from bringing viruses into the pig farm. It isolates the pig house from the outside world to form a "fortress" and reduce the risk of animals carrying viruses. It is the first line of safety protection for the pig house.

[0056] The three-proof net 5 is woven from 304 stainless steel, with a flat surface, standard mesh, and strong impact resistance. It is divided into dust-proof net, insect-proof net, and bird-proof net, with three different specifications suitable for various scenarios.

[0057] The second line of safety protection: air filtration system 6.

[0058] The outside air passes through multiple air filtration devices, which can effectively prevent the original microorganisms such as blue ear disease, classical swine fever, pseudorabies, foot-and-mouth disease, and pancreatic dysentery from entering the pig house and infecting pigs, thus ensuring the health of the pigs.

[0059] The air filtration system 6 adopts a combination of primary efficiency + sub-high efficiency filters, which can not only improve the filtering effect, but also increase the service life of the sub-high efficiency filter and control cost expenditure.

[0060] Reasonable layout according to ventilation filtration method and air filtration level can cut off the main route of virus transmission from air channels to pig houses, reduce the chance of pigs being infected with viruses and becoming ill, and thus achieve excellent production efficiency.

[0061] The W-type filter 13 (also known as an air filter), the combined high-efficiency filter frame 16 materials are divided into: plastic frame, galvanized frame, aluminum frame, stainless steel frame, and the pig house usually uses a stainless steel frame combined high-efficiency filter. The W-type filter 13 has good bacterial filtration performance, and the filter material is folded 180 degrees on both sides to form a wedge-shaped pleat. The deodorizing filter material 29 has two indentations when it is bent, so that it forms a wedge-shaped box-type pleat at the tail end of the partition. The wedge-shaped box-type pleat can prevent the deodorizing filter material 29 from being damaged. The deodorizing filter material 29 is made of high-density paper made of ultra-fine glass fiber. The pleats are used to maximize the effective filtration area of ​​the material, thereby reducing the filtration rate of the deodorizing filter material 29, which is very important for high-efficiency filters. The glass fiber deodorizing filter material 29 is waterproof and flame retardant, and can be used at high temperatures of 1000°F (538℃);

[0062] The third line of safety protection: wet curtain cooling system 7.

[0063] In addition to cooling, the wet curtain 17 also has three different functions: humidification and filtering dust in the air, so more and more farms adopt this cooling and filtering solution.

[0064] The wet curtain 17 is a paper honeycomb structure material, and its working principle is the natural physical phenomenon of "water evaporation absorbs heat". That is, water flows from top to bottom under the action of the earth's gravity, so that the water evenly wets the entire cooling wet curtain wall, and forms a thin water film on the corrugated fiber surface of the wet curtain 17. When the fast-flowing air passes through the wet curtain 17, the air and the water film on the surface of the wet curtain 17 exchange water and gas heat. The water in the water film evaporates after absorbing the heat in the air, taking away a large amount of heat, so that the temperature of the air passing through the wet curtain 17 is reduced, thereby achieving the purpose of cooling.

[0065] The wet curtain cooling system 7 is easy to install, low in cost, low in energy consumption, high in cooling capacity, and high in safety factor. It is suitable for use in pig houses and has good results.

[0066] The fourth line of safety protection: environmental control system.

[0067] The factors that affect pig farming performance mainly include breed, feed, environment and disease prevention and control. Among them, environmental factors are the key factors affecting breeding efficiency, which can directly lead to the occurrence and spread of diseases, and stress factors are also the main cause of disease occurrence.

[0068] Whether it is temperature control, humidity control, or air quality in the pig house, they are all closely related to ventilation. Good ventilation will reduce the discomfort caused by high temperature to pigs, while expelling harmful gases in the pig house to ensure fresh air in the pig house.

[0069] The environmental control system can measure and evaluate the air volume and environment in the house through pressure sensors, temperature sensors, humidity sensors, etc., and will issue an alarm when any abnormal situation occurs.

[0070] When the high-pressure fan is turned on, the positive pressure air supply will cause the filtered air to enter the ceiling air inlet channel 21, and then the air enters the pig house through the ceiling air inlet window 25. Through breathing ventilation, the dirty air in the pig house is discharged to the central ventilation channel 24 through the roof exhaust fan; the dirty air is then filtered out by the deodorization filtration system and discharged to the outside of the house through the roof chimney exhaust fan 9; the external air is then cooled by the three-proof net 5, filter, and wet curtain 17 before entering the house, forming an air circulation.

[0071] The wet curtain cooling system 7 is suitable for use in an environment with high temperature and low humidity. It can not only reduce the temperature in the pig house, but also increase the humidity, making the environment more suitable for pigs to survive.

[0072] The fifth line of safety: deodorization system 10

[0073] A pig farm with an annual output of 100,000 pigs emits about 160kg of ammonia into the atmosphere every hour, which not only affects the health of livestock and poultry, but also affects the normal life of pig farm employees. In addition, the environmental protection requirements for enterprises at home and abroad are becoming increasingly stringent, so how to reduce or even eliminate the gas pollutants discharged from pig houses has become a serious issue for pig farmers.

[0074] The deodorization system 10 is composed of five main devices: deodorization filter material 29, outer frame, water reservoir 31, spray device and electrical control. The pig house exhaust gas is sent to the deodorization system 10 through the fan, and the dust and harmful gas are absorbed by the deodorization filter material 29. The exhaust gas is thus purified and meets the emission standards. The deodorization mode can be constructed according to local conditions.

[0075] The vertical ventilation deodorization mode is to appropriately extend the channel height and the thickness of the deodorization filter material 29 according to the number of piggeries, so as to obtain more filtering area and achieve better deodorization effect. Ammonia removal rate: 60%-80%, hydrogen sulfide and other odor removal rate: 50%-80%, dust removal rate: 60%-80%. More importantly, the deodorization system 10 is highly matched with the front-end air filtration system 6 to form a unified and complete air supply and exhaust solution.

[0076] Pig house with integrated ventilation system with air filtration:

[0077] 1. It can effectively reduce the spread of harmful gases, dust and microorganisms outside the house, block pathogens from entering the house, and prevent cross infection;

[0078] Second: Good ventilation can expel dirty and humid air from the house, take away dust and heat from the house, and replenish dry and clean fresh air to ensure the appropriate temperature in the house, which can reduce stress reactions and reduce the probability of respiratory diseases;

[0079] 3. Treat pig farm odor with water purification to reduce the impact of odor on pig growth and avoid environmental pollution.

[0080] The five safety protection systems are highly compatible to form a complete air supply and exhaust ventilation and filtration system. The pig house using this ventilation system has good ventilation and air exchange, which can discharge the dirty and humid gas in the house, take away the dust and heat in the house, and replenish dry and clean fresh air to ensure the appropriate temperature in the house and reduce stress reactions and respiratory diseases.

[0081] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.
