Sterilization and disinfection purification device and method for air in livestock shed

Abstract

The invention relates to a low-cost sterilization and disinfection purification device and method for air in a livestock shed, which can be used for rapidly and effectively purifying, sterilizing and disinfecting air pollutants in a large-scale livestock shed. The sterilization and disinfection purification device comprises a negative-pressure fan, a positive-pressure fan, an air purification and disinfection system, a dryer and a plasma sterilization device which are controlled by a PLC (Programmable Logic Controller), wherein the inlet end of the negative-pressure fan is communicated with an air outlet of the livestock shed while the outlet end of the negative-pressure fan is communicated with the air purification and disinfection system; the outlet end of the air purification and disinfection system is communicated with the dryer; the outlet end of the dryer is communicated with a plasma sterilizing chamber; and the inlet end of the positive-pressure fan is communicated with the plasma sterilizing chamber while the outlet end of the positive-pressure fan is communicated with an air inlet of the livestock shed. When the device is used for purifying air, the negative-pressure fan is used for extracting polluted air out of the livestock shed, then the polluted air is sequentially introduced into the air purification and disinfection system, the dryer and the plasma sterilization device for sterilization and disinfection, then the treated air is introduced into the livestock shed via the positive-pressure fan; and therefore, the polluted air in the livestock shed is sequentially and circularly treated.

Description

technical field [0001] The invention relates to an air purification device in a poultry breeding house, in particular to a purification device capable of purifying, sterilizing and disinfecting the air in a poultry breeding house and a purification method using the device. Background technique [0002] In recent years, with the popularization of large-scale poultry breeding industry, China's poultry breeding industry has made great progress. However, with the increasing density of large-scale poultry breeding industry, the environment in livestock and poultry houses is deteriorating. , the concentration of harmful gases in the house increases, the dust content increases, and the concentration of microbial aerosols seriously exceeds the standard (especially in winter when closed measures are taken due to the need for heat preservation, the above phenomenon is even more serious), all of which directly threaten the health of the livestock population, and also It seriously threa...

Problems solved by technology

The problems of this equipment are: 1. There is no independent ozone circulation loop, and many ozone bubbles are mixed in the air purification loop of the equipment and the purified air. Inhaling too much ozone can easily cause respiratory diseases of livestock and breeders. At the same time, the equipment in the circuit will be oxidized and corroded by ozone, resulting in a very short service life; 2. The water and air circulation circuits of the equipment are not separated independently, resulting in the cleaning pollutants being easily sucked into the high-pressure cleaning cabin by the high-pressure water pump, resulting in the filter in the cabin and additional The nozzle is easily blocked and unable to work. At the same time, it is difficult to realize the sealing treatment after the filter is replaced, cleaned and repaired in the high pressure chamber, resulting in high manufacturing and maintenance costs; 3. Due to the pollution of the air suction direction and the nozzle spraying The same direction leads to insufficient exchange of polluted air and ozone water, which leads to poor purification and sterilization effects, and cannot meet the purification treatment of long-term air circulation in large-area poultry houses.
