Description

Plasma device for removing odor and maintaining freshness {A PLASMA APPARATUS FOR CLEARING MALODOR}

The present invention relates to a plasma device, and more particularly, to a odor removal and freshness maintenance plasma device for maintaining the freshness of food by generating atmospheric pressure plasma to remove and sterilize a livestock odor.

In recent years, with the continuous increase in meat consumption due to the improvement of living standards according to economic development, the mass supply of livestock products is made due to the development of livestock, while the price and quality of livestock in the livestock field as low-priced meat is imported and supplied in large quantities by trade. competition is taking place.

With this competition, consumers get economic benefits by choosing cheap livestock products with freedom of choice, while producers do not seek to recover the return on investment by increasing purchasing power and reducing production costs to a minimum through advanced differentiation of products. It is an unavoidable situation.

Accordingly, livestock farms have to diversify production facilities to improve quality and focus on cheaper producers.

In addition, in recent years, as environmental problems arise, a plan for a livestock wastewater treatment system for the treatment of various pollutants generated in livestock farmhouses is required.

However, in the case of a livestock wastewater treatment system, it is provided as a facility for purifying and treating livestock wastewater generated by the manure of livestock in the livestock house, and in this case, various odors generated in the livestock house cannot be easily reduced.

The odor generated in the livestock is mainly caused by nitrogen compounds such as ammonia amine, hydrogen sulfide, and sulfide such as mercaptan, which are generated from the excrement of livestock. There was a problem that adversely affected the growth environment and respiratory system, resulting in deterioration of meat quality and pollution of the surrounding air.

In order to solve this problem, Korea Patent No. 0901756 discloses a method of removing odor by spraying diluted sodium hypochlorite on a pig house to supply air from one side of the pig house to the pig room after preheating in the pre-heating room. , The first malodor removal step of evacuating the odor gas generated in the pig room with an exhaust fan to the collection chamber between the inner wall and the outer wall, and then spraying diluted sodium hypochlorite supplied from the sodium hypochlorite generator to adsorb and remove the odor; Secondary odor removal step and odor removal chamber with dilute sodium hypochlorite sprayed from the sodium hypochlorite generator to the spray nozzle of the pipeline connected from the sodium hypochlorite generator by exhausting the unadsorbed odor in the removal step to the odor removal chamber partitioned by a barrier on the outside of the collection room The third stage that absorbs the odor of the malodorous gas passing through the filter by dripping diluted sodium hypochlorite with the spray nozzle of the pipeline connected from the sodium hypochlorite generator to the filter between the cover body and the dripping water collection tank of the filtering device configured in the blocking film of the Disclosed is a odor removal method for pig houses, which removes bad odors from pig houses as a odor removal step.

[0011] However, this prior art has a problem in that it takes a relatively long time to reduce the odor gas, dissolves it in water, or uses a deodorizing filter to reduce the odor gas to a live cell facility, so that the odor reduction efficiency is relatively low.
