Technical Field

The invention belongs to the technical field of ventilation, and particularly relates to a ventilation system for livestock and poultry breeding.

Background

With the mass transfer of productivity, the agriculture has the trend of intensive production and operation, and livestock and poultry breeding is also on scale and rapidly develops. The temperature and humidity of a large-scale livestock and poultry farm need to be adjusted to provide a comfortable temperature and humidity environment. For example, pigs are warm-blooded animals and proper temperature and humidity are important factors in the growth process of pigs. The environment temperature suitable for pig growth is 16-23 ℃, the early stage is 20-23 ℃, and the later stage is 16-20 ℃; under the condition of proper temperature, the relative humidity of the proper environment is 50% -70%. The temperature and humidity of the pigsty are usually regulated by ventilation.

Common ventilation modes of large-scale livestock and poultry farms are as follows: a natural ventilation mode, a wet curtain plus fan system mode; the air flow direction can be divided into transverse ventilation, longitudinal ventilation and vertical ventilation. Different ventilation methods, the air flow direction brings different ventilation effect, but the ubiquitous farm interior gas velocity of flow is inhomogeneous, the fresh degree difference of air is big, the room temperature that is close to the air intake is low, the air is fresh, the air quality is poor more nearly from the air outlet, above ventilation methods easily cause harmful virus and the gaseous cross propagation in whole farm in the farm simultaneously, after the beasts and birds in one of them colony house are sick, the beasts and birds in whole farm are all easily infected with the disease, the risk that the beasts and birds were sick has been improved. The method is embodied in the following three aspects: 1. the air flow entering the culture area flows from one direction to the other direction integrally, and the colony house in the downwind direction is influenced by the fact that the upwind passes through the colony house, namely if the livestock in the colony house in the upwind direction are infected by viruses, the livestock in all the colony houses in the downwind direction can be influenced along with the spread of the air flow; 2. airflow always transversely passes through the housing from a certain height above the housing, so that few effective airflow really reaches the livestock and poultry breathing area, namely the utilization rate of fresh air is low, and the energy consumption is invisibly increased; 3. the stink of the excrement of the livestock and the poultry in the septic tank is spread upwards, and the growth environment and the comfortable feeling of the livestock and the poultry are directly influenced. In addition, the temperature of the large-scale livestock and poultry farm is reduced only by the wet curtain at present, but the outdoor temperature and humidity of part (high-temperature high-humidity) climate areas are high, and the temperature and humidity control requirements of large-scale cultivation cannot be met by a wet curtain cooling mode.
