Embodiment Construction

[0023] see Figure 1 to Figure 5 , a pig house ventilation system in a cold area includes a pig house and a ventilation system: the pig house is composed of an insulation layer 6, a feeding area 7, a water bubble excrement drainage ditch 20, and a corridor 10. The insulation layer 6 and the feeding area 7 are located above the ground 24, and the water bubble The excrement drainage ditch 20 is positioned at the ground 24 below, and the insulation layer 6 is provided with a skylight 8, and the raising area 7 is divided into several raising units 30, and each raising unit 30 has aisle 32 and 1 to 2 rectangular group breeding pigpens 31, two pig houses. There are south windows 2 and north windows 11 on the side; the ventilation system includes air inlet ducts and exhaust ducts, and the air inlet ducts are sequentially composed of fresh air fans 25, heat conversion devices 15, temperature control rooms 9, air inlet pipes 5, fresh air outlets 3, The guard plate 4 is composed of; the...

Abstract

The invention discloses a pigsty ventilation system for cold regions. The pigsty ventilation system for the cold regions comprises a pigsty and a ventilation system. The ventilation system comprises an air inlet pipeline and an exhaust pipeline, and the air inlet pipeline sequentially comprises a fresh air fan, a heat conversion device, a temperature control room, an air inlet pipe, fresh air openings and protective plates; the exhaust pipeline sequentially comprises first exhaust outlets, second exhaust outlets, a first exhaust pipe, a second exhaust pipe, a guide valve, the heat conversion device, a waste gas treatment room and an exhaust fan. The pigsty ventilation system has the advantages that lost heat of the pigsty can be effectively recycled, the pigsty is good in heat insulation and high in waste gas removal efficiency and can be uniformly ventilated, energy can be saved, survival environments for pigs can be obviously improved, environmental pollution can be abated, and the like.

Description

technical field [0001] The invention relates to the field of livestock and poultry breeding, and relates to a ventilation system for pig houses in cold regions. Background technique [0002] There is a large temperature difference between indoor and outdoor in pig houses in cold regions in winter. Maintaining suitable temperature and humidity in pig houses and reducing the concentration of harmful gases are extremely important technical means for pig breeding in cold regions. Existing pig houses in cold regions generally achieve heat preservation by sealing and installing heating equipment, and reduce humidity and harmful gas concentrations in pig houses by strengthening ventilation. They are contradictory. In actual production, one often loses sight of the other, and with the entry of cold air, it is bound to generate air flow in the house to form cold wind, which is easy to cause pigs to catch a cold. Contents of the invention [0003] The invention mainly solves the te...
