A breeding system and ventilation method with low energy consumption and capable of reducing the concentration of harmful gases in the house

Abstract

The invention discloses a breeding system and a ventilation method with low energy consumption and capable of reducing the concentration of harmful gases in the house. The breeding system includes an air chamber, a breeding house and a ventilation room. There are a number of waste gas exhaust branch pipes on the side wall of the air duct. Openable sliding curtains are installed at both ends of the breeding house. Adjustable air inlet windows and wet curtains are installed at the front end of the air chamber. Solar collectors are installed outside the adjustable air inlet windows. The hot plate is provided with a roll-up curtain that can be folded and unfolded outside the wet curtain, and the upper part of the breeding house is provided with an air inlet channel, and fans are provided on the rear side wall of the ventilation room and at the end of the trench air duct. The breeding system adopts 4 levels of organized ventilation according to the different temperatures outside the house, which can achieve high air freshness, low energy consumption operation and precise ventilation in the breeding house, and create a suitable growth space for livestock and poultry, especially in the process of manure treatment. The vertical airflow organization from top to bottom can effectively inhibit the upward movement of toxic and harmful gases whose concentration suddenly rises, and be discharged from the breeding house as soon as possible.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry breeding facilities and equipment, and relates to a breeding system, in particular to a breeding system and a ventilation method with low energy consumption and capable of reducing the concentration of harmful gases in the house. Background technique [0002] China has a large population, and the consumption of livestock and poultry products is huge. According to the statistics of the National Bureau of Statistics in 2017, the output of pig, beef, mutton and poultry meat in 2017 was 84.31 million tons, of which, the output of pork was 53.4 million tons, and the output of poultry meat was 18.97 million tons. Products account for about 86%. In order to meet the growing market demand, the production efficiency of livestock and poultry has been gradually improved, and the way of raising livestock and poultry in the past has gradually developed from free-range breeding outside the house t...

Problems solved by technology

However, increasing the ventilation rate of the livestock and poultry house will greatly increase the energy consumption cost of the livestock and poultry house, and it is also a major cause of cold stress in the livestock and poultry house

Although starting the exhaust fan on the side wall of the septic tank can reduce the harmful gas in the septic tank from rising to the animal living area, but because the effective radius of the exhaust fan is limited, the animal living area often has a phenomenon of high local concentration of harmful gas, which cannot be completely improved Ventilation environment in the house
