Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of breeding, in particular to a multi-layer positive pressure ventilation filter used in the breeding industry. Background Art
[0002] The technology of centralized breeding in breeding houses is becoming more and more popular. When centralized breeding is carried out in breeding houses, in order to reduce the impact of the external environment on breeding, the breeding houses are usually set to a relatively closed state. During the livestock and poultry breeding process, a large amount of heat and water vapor will be generated due to the metabolic activities of livestock and poultry, and oxygen will be continuously consumed and harmful gases such as carbon dioxide will be produced, causing the gas composition in the breeding house to change and affecting the breeding of livestock and poultry. Therefore, ventilation is an important means of regulating the environment of the breeding house. By introducing fresh air into the breeding house, not only the dirty air in the house can be discharged, but also the excess water vapor and excess heat can be discharged.
[0003] Existing ventilation methods mostly use positive pressure ventilation. Fresh air is blown into the breeding room by a positive pressure fan. Compared with the negative pressure ventilation mode, it avoids the infiltration of untreated fresh air from other gaps. Although the positive pressure ventilation effect is more stable, the fresh air directly enters the livestock and poultry house without passing through the air filtration system, posing a hidden danger to the safety of breeding organisms. Therefore, ventilation filters that filter fresh air are particularly important. Utility Model Content
