Description

Barn odor reduction system {Odor reduction system for stable}

The present invention relates to a livestock odor reduction system for reducing odors generated in livestock houses using livestock, and more specifically, water used for removing odors and dust is sterilized with ozone and recycled to improve deodorization efficiency and hygiene. It is intended to provide a system for reducing the odor of livestock houses so that it can be provided and the operation status can be checked with the naked eye at all times.

In general, in the case of livestock such as pigs and cows, the less digestible protein component in the feed produces substances such as NH4 (ammonium ion) and H2S (hydrogen sulfide), which causes bad odor. Fugitive dust is generated and the air quality inside the livestock is lowered.

Various techniques have been proposed to treat the above odor and scattered dust.

Representative examples are the device for removing odor substances for livestock use in Korean Patent Publication No. (B1)10-1713908 (June 9, 2017) and the effective removal of odor in Korean Patent Publication No. (B1)10-1402281 (June 2014) Eco-friendly livestock houses that can be used are provided.

In addition, methods for removing odors are provided as a water treatment method, and as a representative example, a deodorizing device for installation of an exterior wall of a livestock house in Republic of Korea Patent Publication (B1)10-2042631 (2019.11.08.) is proposed, and the configuration is In the deodorizing device for installing the outer wall of the barn for deodorizing the odor generated from the inside with water sprayed through the deodorizing device installed adjacent to the outer wall of the barn; The deodorizing device includes: a guide plate having a tapered upper part and narrower toward the lower part for introducing odor into an inlet hole formed in the upper part of the casing and moving it to the lower part of the casing; a ring-shaped spray nozzle installed in the middle of the guide plate to spray water downward for deodorization; an exhaust hole formed along the entire surface of the upper outer periphery of the casing so that the odor passing through the guide plate is deodorized by the sprayed water and then flows backward to the upper portion to be exhausted to the outside; a pump and a supply pipe installed to supply water to the injection nozzle; a supply valve and a water supply valve installed in the middle of the supply pipe; It is configured to include a drain valve installed under the casing.

However, in the case of the prior art, since the slot is narrowed by the tapered guide plate, there is a problem in that the pressure loss is large and the performance of the blower is deteriorated. Sludge was deposited, which also caused problems such as malfunctioning of supply pipes and pumps.
