Description

Multi-stage deodorization device using dehumidification, cleaning, and photolysis {MULTISTAGE ODOR REMOVAL APPARATUS USING DEHUMIDIFICATION, WASHING AND PHOTOLYSIS}

The present invention relates to a multi-stage deodorization device using dehumidification, cleaning, and photolysis. More specifically, it relates to dehumidification and cleaning of high-temperature, high-humidity, high-concentration odor gases, and treating them with UV photolysis to discharge purified air. and a multi-stage deodorization device using photolysis.

With the increase in population and industrial development, the discharge of domestic and industrial wastewater increases, and the number of livestock raised as part of providing food resources to support the population increase also increases, and the emissions resulting from the raising of these livestock also increase. The amount of livestock manure produced is also bound to increase.

Odor-causing substances such as domestic and industrial wastewater, livestock manure, and garbage, and odor-causing substances such as ammonia, hydrogen sulfide, and amines generated during the anaerobic fermentation process may cause complaints from surrounding areas or cause discomfort to workers. Resistance to liquid fertilizer production facilities is being created for aesthetic reasons rather than efficacy.

A method of producing liquid fertilizer is being considered as a way to treat these odor-causing substances.

To date, most liquid fertilizers are produced through a series of processes such as simple storage, anaerobic fermentation, and aerobic fermentation, followed by fermentation for a certain period of time and then conversion to liquid fertilizer.

The odor components generated in the above-described liquid fertilizer production method include ammonia, hydrogen sulfide, amines, etc., which are odor components generated from livestock manure itself or during anaerobic and aerobic fermentation processes.

The above-mentioned ammonia, hydrogen sulfide, amines, etc. are in very high concentrations. In particular, ammonia and hydrogen sulfide are inorganic compounds and have the property of not being removed by methods such as deterioration, carbonization, or catalytic oxidation. In order to treat them, chemical treatment, biological treatment (bio treatment) It has the problem of requiring separate treatment facilities such as filters.

In addition, ammonia and hydrogen sulfide are gases with high water solubility and can be largely removed by wet cleaning, but there is a problem in that the amount of wastewater generated increases and a separate wastewater treatment facility must be added.

In particular, ammonia is a basic gas that is soluble in acids but not in bases. Hydrogen sulfide is the opposite of ammonia and is insoluble in acids but has a very high solubility in bases. When choosing a chemical treatment method, these two It was necessary to select a process that took into account the physical and chemical properties of the gas.

As a method to remove odorous components generated from livestock manure as described above, activated carbon adsorption, chemical cleaning, biotrickling filter, and soil deodorization methods are currently mainly used.

Registered Office No. 20-0468971 (hereinafter referred to as Prior Art 1) includes a housing comprised of a deodorizing chamber connected to an intake duct through which odorous gas flows in and an exhaust duct through which purified odorous gas is discharged; an air fan provided inside the suction duct to suck odorous gas into the suction duct; Plasma processing means configured inside the suction duct to decompose and process the odorous gas sucked by the air fan through plasma by corona discharge; a chemical sprayer configured inside the deodorizing room to neutralize the odorous gas by spraying a neutralizing agent into the space of the deodorizing room when the odorous gas plasma decomposed by the plasma processing means flows into the deodorizing room; a water collection tank located below the deodorization chamber to collect the neutralizing agent reacted with the odor gas; A neutralizing agent supply tank configured on one side of the water collection tank to supply a neutralizing agent to the water collection tank through a chemical pump; a circulation pump that supplies the neutralizing agent collected in the water collection tank to a chemical sprayer to circulate the neutralizing agent so that the neutralizing agent is sprayed into the space of the deodorizing room; and a filtering means configured in a corresponding portion of the deodorizing chamber connected to the discharge duct through which the odor gas neutralized by the neutralizing agent is discharged, to filter out odorous substances in the odor gas that have not been neutralized by the neutralizing agent and then discharge only the neutralized gas. In the complex livestock manure odor gas removal device including, an inflow sensor is configured inside the suction duct to measure the wind volume, temperature, and humidity of the odor gas, and an odor gas is filtered through ultraviolet rays on one side of the filtration means. An ultraviolet lamp for decomposition is configured, and a pH sensor is configured to detect the concentration of odorous gas or the acidity of the neutralizer in the deodorization room or collection tank, and a device at the outer lower end of the deodorization room to maintain the deodorization room at a constant temperature. A composite livestock waste odor gas removal device characterized by being provided with an electric heating means was disclosed.

However, prior art 1 simply inhales the odorous gas and mixes it with the neutralizing agent, so there is a problem in that the mixing of the odorous gas and the neutralizing agent is difficult.

In addition, Patent Registration No. 10-1932743 (hereinafter referred to as Prior Art 2) includes an external pump for pumping deodorizing liquid; As the deodorizing liquid transferred from the external pump passes through, odorous gas is sucked in using the Venturi principle, shear stress is generated, and the first deodorization occurs by mixing with each other; A connection pipe with one end connected to the venturi pipe and the other end closed; a deodorizing tank in which the other end of the connecting pipe is stored in the lower portion and is filled with a deodorizing liquid; A plurality of vortex diffuser devices that are radially connected to the other end of the connection pipe to induce a vortex of the odor gas transported in the connection pipe and discharge it to the outside to mix the odor gas with the deodorizing liquid of the deodorizing tank to perform secondary deodorization; a guide film formed in a structure in which the upper part is closed and the lower part is open, and is covered with the plurality of vortex diffuser devices to guide the odor gas emitted from the plurality of vortex diffuser devices to flow in a zigzag manner; and an outlet through which odorous gas rising through the guide membrane is released. Disclosed is an odor remover characterized by comprising a.

However, prior art 2 consisted of a single deodorizing tank, so although its structure was simple, it was difficult to respond to various types of odors such as acidic odors and basic odors, and accordingly, the odor removal efficiency also had the disadvantage of being relatively low.

Figure 2 is a conceptual diagram schematically showing the direction in which odorous gas is discharged in a vortex rotation manner from the wet scrubber tower 200, which is the main part of a multi-stage deodorization device using dehumidification, cleaning, and photolysis according to an embodiment of the present invention.

As shown in FIG. 1, in the present invention, the heat exchanger 100 primarily dehumidifies and deodorizes high-temperature and high-humidity high-concentration odorous gases, the wet scrubber 200 decomposes the odorous gas, and the air ejector 300 removes odorous substances. Implementation of a structure in which various gases are supplied, the demister filter assembly (400) secondarily dehumidifies and deodorizes the odorous gas, the UV light decomposer (500) decomposes the odorous substances, and then the discharge means (600) discharges the purified gas. Examples can be applied.

The heat exchanger 100 performs primary dehumidification and deodorization of the odorous gas by exchanging heat with the high-temperature, high-humidity, high-concentration odorous gas.

The wet scrubbing tower 200 decomposes the odorous gas by contacting a cleaning liquid with the odorous gas that has been dehumidified and primarily deodorized as it passes through the heat exchanger 100.

The air ejector 300 is installed in the circulating water supply line of the wet cleaning tower 200 to supply pure oxygen, OH radicals, ozone, and hypochlorous acid for cleaning liquid, fresh air, and deodorization.

The demister filter assembly 400 is mounted on the lower end of the gas discharge pipe 800 connected to the ceiling of the wet scrubbing tower 200 and is disposed around the lower outer surface of the wet scrubbing tower 200 to maintain the gas discharge pipe 800.

In addition, the wet washing tower 200 uses a swirling vortex method to increase the amount of contact between the odorous gas and the cleaning liquid, thereby increasing the amount of decomposition of the odorous gas.

Additionally, the air ejector 300 was intended to increase deodorizing power by installing it in the cleaning liquid supply line of the wet cleaning tower 200.

And the demister filter assembly maximizes convenience of maintenance and dehumidifies and deodorizes by lowering the installation location.

In addition, the UV photodecomposer 500 generates ozone and OH radical substances to decompose odorous substances and minimizes the generation of ozone by controlling the concentration of odorous substances.

In addition, the discharge means 600 removes odorous gas through negative pressure in the purified gas blowing section through a suction process and reduces the vibration generated at this time with a flexible joint to be described later, thereby reducing damage caused by vibration of the shear cavity and buffer. It will be possible to prevent damage to the blower 620 due to overflow through the chamber 610.

You can see what is mounted on the table.

At this time, the heat exchanger 100 and the refrigerator 110 remove the odorous substances by performing a dehumidification process of the odorous gas containing a large amount of moisture and remove the cleaning liquid charged in the wet scrubbing tower 200, which will perform the subsequent process. By reducing the degree of contamination, it is possible to increase the efficiency of the deodorization process and reduce maintenance costs due to replacement and exchange of cleaning fluid.

Meanwhile, the wet washing tower 200 is formed on the hollow washing tower main body 210 and the lower outer peripheral surface of the washing tower main body 210, and has a gas inlet port ( 211) and a gas formed on the ceiling of the washing tower main body 210 and connected to the gas discharge pipe 800 so that odorous gas decomposed in contact with the washing liquid sprayed down from the upper inner part of the washing tower main body 210 is discharged.

Accordingly, the odorous gas flowing in from the gas inlet port 211 rotates toward the gas discharge port 212 as shown in FIG. 2, generates a vortex, and is discharged upward.

That is, the wet scrubbing tower 200 discharges odorous gas in a swirling vortex manner as shown.

That is, wet cleaning is achieved by using a vortex in the flow of odorous gas to increase the time the odorous gas stays inside the cleaning tower main body 210 and at the same time increasing the contact time with the cleaning liquid sprayed and falling through the cleaning liquid spray nozzle 221. This will maximize efficiency.

Meanwhile, the air ejector 300 is installed to interconnect the cleaning liquid discharge pipe 220 and the return pipe 250.

The air supply port 230 is formed between the inlet and outlet sides of the air ejector 300, and fresh air is injected through the air supply port 230, or pure oxygen, OH radicals, ozone, and hypochlorous acid are used for deodorization purposes.

Conventional demister filters were generally installed at the top of the wet scrubbing tower (200).

This top-mounted demister filter had a problem in that as the height of the wet washing tower 200 increased, replacement and inspection were difficult, and the risk of causing hazards and safety accidents increased due to replacement and inspection work.

Taking this into account, the demister filter assembly according to the present invention is installed at the bottom of the ground around the wet washing tower 200, that is, the circulating fluid tank 240 below the washing tower main body 210, so that replacement and inspection are easy. As a result, risks and concerns about safety accidents can be minimized.

On the other hand, the UV photodecomposer 500 is a photodecomposer having a decomposer inlet port 511 connected to the outlet side of the demister filter assembly and a decomposer outlet port 512 connected to the inlet side of the discharge means 600.
