Description

A fully enclosed pig house ventilation system

technical field

The utility model relates to a ventilation system for a fully enclosed pig house, which belongs to the field of breeding facilities, in particular to a ventilation system for a fully enclosed pig house after the air is sterilized by lime water.

Background technique

Pig house ventilation system, a system for exchanging the air inside the pig house. Existing farms used the spray disinfection method to disinfect the air and the fumigation method to disinfect the air to the ventilation of the pig house. The spray disinfection method is to spray chlorine dioxide or sodium hypochlorite disinfectant inside the intake pipe of the pig house. This method is simple and effective, but the cost is high, and the air disinfection is not complete and there are dead ends, that is, the fast-flowing air and disinfection The liquid is not mixed evenly, and after the air entering the pig house flows around, part of the gas without the disinfectant solution cannot play a role in disinfection, and the air without the disinfectant solution may even contain germs to destroy the interior of the pig house. Fumigation air disinfection, that is, to place a container containing peracetic acid or hydrogen peroxide inside the pig house, and then turn on the ventilation fan inside the pig house to make the air flow to achieve the purpose of fumigation. This method is simple and effective, but the inside of the pig house The air in the pig house cannot be replaced, and long-term airtightness will cause hypoxia inside the pig house. If the window is opened for ventilation, the fresh air entering the pig house will bring in new germs, making the pig house unable to achieve the purpose of sterility . Therefore, the above two air disinfection methods cannot achieve the aseptic effect inside the piggery.
