Description

Organic Waste Multistage Odor Removal System}

The present invention relates to a multi-stage odor removal system for removing odors generated from organic wastes by introducing them from the outside, and more particularly, from organic wastes such as sewage, wastewater treatment plants, excreta treatment plants, animal sheds, and leachate treatment plants of waste treatment facilities. It relates to a multi-stage odor removal system for organic waste that removes the generated odor and discharges fresh air to the outside.

Until now, most of the liquid fertilizer production methods are produced through a series of processes in which they are converted into liquid fertilizer after maturing for a certain period of time through simple storage or anaerobic fermentation and aerobic fermentation.

However, during this process, civil complaints in the surrounding area occur due to odor-causing substances present in livestock manure itself and odor substances such as ammonia, hydrogen sulfide, and amines generated in the anaerobic fermentation process, or cause discomfort from workers, resulting in liquid fertilizer production facilities. It creates a sense of rejection for aesthetic reasons rather than efficacy for

The malodorous components generated in the production method of the liquid fertilizer are ammonia, hydrogen sulfide, amines, etc., which are malodorous components generated in the livestock manure itself or during anaerobic and aerobic fermentation, and the ammonia, hydrogen sulfide, amines, etc. Hydrogen sulfide and hydrogen sulfide are inorganic compounds that are not removed by methods such as deterioration, carbonization, or catalytic oxidation, and thus have a problem in that separate treatment facilities such as chemical treatment and biological treatment (bio filter) are required to treat them.

In addition, the ammonia and hydrogen sulfide are gaseous with high solubility in water and can be removed considerably by wet cleaning, but there is a problem in that a separate wastewater treatment facility has to be added due to an increase in the amount of wastewater generated. In particular, ammonia is a basic gas, which is well soluble in acid but insoluble in base, and hydrogen sulfide is not soluble in acid, opposite to ammonia, but has very high solubility in base. It was necessary to select a process in consideration of the physical and chemical properties of the gas.

As a method for removing malodorous components generated from livestock manure as described above, an activated carbon adsorption method, a chemical washing method, a biotrickiling filter, a soil deodorization method, and the like are mainly used.

Korean Registered Office No. 0486971 is a housing comprising a deodorizing chamber connected to a suction duct through which odor gas is introduced and an exhaust duct through which purified odor gas is discharged; An air fan provided inside the suction duct to allow odor gas to be sucked into the suction duct; Plasma processing means configured inside the suction duct so that the odor gas sucked by the air fan is decomposed and processed through plasma by corona discharge; A chemical liquid sprayer configured inside the deodorization chamber to neutralize the odor gas by spraying a neutralizing agent into the space of the deodorization chamber when the odor gas plasma decomposed by the plasma processing means flows into the deodorization chamber; A collection tank configured under the deodorization chamber to collect the neutralizing agent reacted with the odor gas; A neutralizing agent supply tank configured at one side of the collecting tank to supply a neutralizing agent to the collecting tank through a chemical pump; A circulation pump circulating the neutralizing agent to supply the neutralizing agent collected in the water collecting tank to the chemical liquid sprayer so that the neutralizing agent is sprayed into the space of the deodorization chamber; And a filtering means configured at a corresponding part of the deodorization chamber that is communicated with the discharge duct through which the odor gas neutralized by the neutralizing agent is discharged, and filters the odor substances of the odor gas not neutralized by the neutralizing agent, and then discharges only the neutralized gas. In the complex livestock manure odor gas removal device comprising a, the inlet sensor for measuring the air volume, temperature, humidity, etc. of the odor gas is configured inside the suction duct, and the odor gas is decomposed through ultraviolet rays at one side of the filtering means. An ultraviolet lamp is configured, and a pH sensor that detects the concentration of odor gas or the acidity of the neutralizing agent is configured in the deodorization chamber or the collection tank, and an electricity that maintains the deodorization chamber at a constant temperature at the outer lower end of the deodorization chamber. A complex type livestock manure odor gas removal device, characterized in that the heating means is provided.

However, in the prior art, by simply inhaling the malodorous gas and mixing it with the neutralizing agent, there is a problem in that the malodorous gas and the neutralizing agent are not well mixed.

In addition, Korean Patent Registration No. 10-1932743 is an external pump for pumping a deodorant liquid; A venturi tube through which the deodorizing liquid transferred from the external pump passes and the odor gas is sucked in the venturi principle, and shear stress is generated and mixed with each other to perform primary deodorization; A connection pipe having one end connected to the venturi pipe and the other end closed; A deodorizing tank in which the other end of the connection pipe is accommodated in a lower portion and filled with a deodorizing liquid; A plurality of vortex diffusers which are radially connected to the other end of the connection pipe to induce a vortex of the transported odor gas from the connection pipe and discharge it to the outside so that the odor gas is mixed with the deodorizing liquid of the deodorizing tank to perform secondary deodorization; A guide membrane formed in a structure in which the upper part is closed and the lower part is opened, and is covered with the plurality of vortex diffusers to guide the odor gas discharged from the plurality of vortex diffusers to flow in a zigzag manner; And an outlet through which odor gas rising through the guide membrane is discharged. Disclosed a malodor remover comprising a.

However, since the prior art is composed of a single deodorizing tank, its structure is simple, but it has been difficult to cope with various odors such as acidic and basic odors, and accordingly, there is a disadvantage in that the odor removal efficiency is not relatively high.
