Description

Air purification equipment for livestock facilities {DEVICE FOR CLEANING AIR FOR LIVESTOCK FACILITY}

The present invention relates to an air purification device for livestock facilities, and more particularly, a physical method as well as a biochemical method for removing polluted air discharged in a state containing a large amount of odors or pollutants from livestock facilities for livestock livestock or manure treatment. It is composed of a module that treats various odors and pollutants effectively, and it is configured to select, arrange, and connect various modules as needed.

In general, livestock facilities are expanding day by day thanks to automation and mechanization, and because of this, high-density livestock are grown in a limited place, so the problem of air and water pollution due to livestock manure generated in large quantities is emerging. In particular, in the process of raising livestock as well as in the process of handling livestock manure, a bad odor is inevitably generated.

Furthermore, according to the Bad Odor Prevention Act (Ministry of Environment), which came into effect in February 2005, from January 1, 2006, regulations on the emission of designated odor gases such as ammonia and hydrogen sulfide were implemented for livestock facilities with an area of 50 m2 or more for pig breeding facilities. there is. This odor prevention law is a situation that livestock farms must strictly comply with along with the Wastewater Management Act, and accordingly, the need for a system to remove the odor gas present in the air discharged from the livestock facility is growing.

In general, the main components of odors generated from livestock facilities such as livestock or livestock manure compost are hydrogen sulfide (H2S) and ammonia (NH3). causes

As a method for removing the odor gas discharged from livestock facilities that cause various problems as described above, there are a cooling condensation method, a high temperature oxidation (thermal incineration) method, a catalytic oxidation method, an adsorption method, a chemical treatment method, and a biological treatment method. is being used

For example, Korean Patent No. 10-1465296 (Odor purification method and its purification apparatus, 2014.11.19) has been disclosed as a cooling condensation method, and Korean Patent Registration No. 10-1178999 as a high temperature oxidation (thermal incineration) method. (A system and method for removing odor of livestock manure using corona discharge, August 27, 2012) and Republic of Korea Patent No. 10-1697768 (A device for removing odor for livestock manure, January 12, 2017) are disclosed, and the catalytic oxidation method Korean Patent No. 10-0843986 (High Efficiency Odor Removal Device, 2008.06.30) and Korean Patent No. 10-1087052 (Liquid Complex Mineral Microbial Livestock Odor Removal Agent, 2011.11.21) have been disclosed as Republic of Korea Patent Registration No. 10-0523757 (deodorization device for odor generating facility, October 18, 2005) and Korean Utility Model No. 20-0446051 (device for removing odor from livestock manure, September 11, 2009), which are technologies using an adsorbent, are disclosed. Republic of Korea Patent Registration No. 10-0984387 (compact type livestock manure odor gas removal device, 2010.09.20) and Korean Utility Model No. 20-0468971 (complex type livestock manure odor gas removal device, 2013.09.04) and the like are disclosed, and Korean Patent Registration No. 10-0490800 (compost biofilter and method of removing odor gas using the same, 2005.05.12), which is a technology using a biofilter such as compost or wood chip as a biological treatment method and Republic of Korea Patent Registration No. 10-1402281 (an eco-friendly livestock house capable of effectively removing odors, 2014.05.26), etc. are disclosed.

However, the conventional malodorous gas removal apparatus is mainly configured to remove the malodorous gas by using only one of the above methods. Not only is there a limit to the method, but the configuration implementing the method has a problem in that the efficiency of removing odor gas is significantly reduced due to the increase in fatigue caused by the long purification operation.

In addition, in the case of a malodor gas removal device in which two or more methods are combined, it is difficult to install and operate them due to the large size of the entire apparatus, but also to change, add, or delete methods because the composition implementing the complex method is fixedly designed. has the disadvantage of being impossible.

To this end, the scrubbing drum 22 has a height of a cylindrical body that fills all the width of the scrubber case 21, so that the contaminated air introduced into the scrubber case 21 must be configured to face the scrubbing drum 22 . The polluted air encountered with the scrubbing drum 22 passes through the scrubbing drum 22 and comes into contact with the treated water W soaked in the treated water carrier 23 filled therein to neutralize dust or contaminants or will be processed to be removed.

On the other hand, as described above, in a state in which the scrubbing drum 22 is horizontally placed across the scrubber case 21 in a rotatably supported state, the portion located at the lower part of the outer periphery of the scrubbing drum 22 is It is immersed in the treated water (W) contained in the treated water tank 25 located at the lower part of the scrubber case 21, so that the lower part at the outer periphery of the scrubbing drum 22 is clogged with the treated water (W). Thus, the contaminated air does not pass from the outer periphery of the scrubbing drum 22 to the lower part.

In addition, in a state in which the scrubbing drum 22 is rotatably supported by horizontally placing the scrubber case 21 in the transverse direction as described above, Between the outer circumferential surface of the upper inner surface of the scrubber case 21 and the outer periphery of the scrubbing drum 22 to prevent the contaminated air from passing through the gap between the outer circumferential surface and the inner surface of the upper part of the scrubber case 21, A sealing part 26 for closing the gap is installed inside the scrubber case 21 .

The microbial agent dropped from the bio-filter part 42 is recovered to the microbial agent supply tank 44 through the drain pipe 442 .

The second bio-processing module 50 is configured to include a bio-bed filled with hay or wood chips 52 flowing through contact with the polluting gas flowing in from the first bio-processing module 40 .

Referring to the drawings, the second bio-processing module 50 has a structure in which dry clay or wood chips 52 are filled inside a bed case 51 having an inlet 511 formed at the lower portion and an outlet 512 formed at the upper portion. has The inlet 511 of the bed case 51 is connected to the outlet 412 of the first bio-processing module 40, and the contaminated air flows into the inside of the bed case 51 through the inlet 511. , some pollutants are decomposed by microorganisms while passing between the hay or wood chips 52, and the introduced contaminated air is decomposed.

The air purification apparatus for livestock facilities described above and shown in the drawings is only one embodiment for carrying out the present invention, and should not be construed as limiting the technical spirit of the present invention. The protection scope of the present invention is defined only by the matters described in the claims below, and improved and changed embodiments without departing from the gist of the present invention are obvious to those of ordinary skill in the art to which the present invention belongs.
