Description

Complex deodorizing device{Apparatus for removing malodor gas}

The present invention relates to a complex deodorizing apparatus, and more particularly, to a complex deodorizing apparatus capable of removing odors, dusts, or odors generated at industrial sites when compost is made using livestock manure.

As the livestock industry has become more specialized and larger, the management of pollution from livestock farms has emerged as an important issue. In particular, odors generated from farms can seriously damage neighboring residents.

The methods currently used to treat manure in livestock farms can be largely divided into composting and liquefaction.The method of liquefaction is to separate the mixed manure into solid-liquid and then compost solids, and urine to convert organic matter into safe substances by aerobic microorganisms. It can be converted to produce liquid manure that does not smell bad, and the use of liquid manure and compost using livestock manure as an alternative fertilizer for chemical fertilizers is increasing rapidly.

The odor generated in the shed is mainly produced by the anaerobic decomposition reaction of manure, and livestock manure contains organic substances and nutrients used as energy sources of naturally occurring microorganisms.

When such animal manure is decomposed by microorganisms, various gases and volatile substances are generated. When the decomposition of livestock manure occurs anaerobic, these gases and components have a foul odor, and when decomposed aerobic, mainly carbon dioxide, water and a small amount of ammonia are generated.

In addition, organic substances in livestock manure are mainly composed of proteins, carbohydrates and fats, and when proteins are anaerobicly decomposed, ammonia and volatile organic acids are formed. And amino acids containing sulfur are decomposed into sulfides and mercaptans that are harmful to the human body.

In particular, ammonia is a representative odorous substance and is generated during the decomposition process of manure, and the amount of ammonia increases at high temperatures. Ammonia is a colorless and irritating toxic gas. Ammonia not only causes a serious odor, it can also cause diseases of the respiratory system.

In the process of processing livestock manure, in addition to odor substances, dust and dust are caused together, and odor substances are easily adsorbed to the dust dust.

Since most of the odorous gases and dusts generated in such barns or livestock manure composting facilities are harmful to workers, a device for collecting and discharging odors is essential in livestock manure composting facilities.

In addition, odors or gases harmful to the human body are generated in industrial sites, etc., and such odors and gases need to be removed.

On the other hand, the conventional complex deodorizing device has a problem in that the structure is complicated and the overall size of the device increases in order to remove odors from a large amount of gas because the deodorization efficiency is low.

Hereinafter, a composite deodorizing apparatus according to each embodiment of the present invention will be described with reference to the accompanying drawings.

Embodiment 1

The complex deodorization apparatus according to the first embodiment of the present invention is a spray chamber 100, a pretreatment tank 200, a defoaming pump 300, a washing water tank 400, and washing water as shown in FIGS. It consists of a configuration including a pump 500.

As shown in FIG. 1, the injection chamber 100 is installed above the pretreatment tank 200. An inlet 101 through which gas is introduced is formed in the upper part of the injection chamber 100, and in the lower part of the injection chamber 100, the gas and washing water are inserted into the pre-treatment bath 200 to deliver the gas and washing water to the pre-treatment bath 200. The supply pipe 110 is formed. The lower end of the supply pipe 110 is installed to contact the water surface of the washing water stored in the pretreatment tank 200.

In addition, an injection nozzle 120 is installed in the injection chamber 100 to inject the washing water toward the introduced gas. The injection nozzle 120 primarily absorbs and removes harmful gases and dust by injecting washing water when gas flows into the injection chamber 100. And the nozzle cap 130 is coupled to the spray nozzle 120. As shown in FIG. 2, a plurality of spray holes 131 are formed in the nozzle cap 130, and washing water is sprayed through the plurality of spray holes 131. The nozzle cap 130 has a structure that can be assembled and separated from the spray nozzle 120.

As shown in FIG. 2(a), the injection hole 131 of the present invention has a cross-sectional size extending toward the injection chamber 100. In the drawing, the injection hole 131 gradually expands toward the right. Accordingly, when the washing water is sprayed through the spray nozzle 120, foreign substances contained in the washing water are filtered by the nozzle cap 130. At this time, a foreign material smaller than the minimum diameter of the spray hole 131 easily passes through the spray hole 131, and a foreign material larger than the minimum diameter of the spray hole 131 does not pass through the spray hole 131.

However, when the diameter of the spray hole 131 is constant or the size of the spray hole 131 is gradually smaller, contrary to the present invention, when the size of the foreign matter is equal to or almost the same as the minimum diameter of the spray hole 131, the After the foreign material is inserted into the injection hole 131 by pressure, it is fixed inside the injection hole 131 to block the injection hole 131. In this case, the spraying performance of the washing water decreases, and the purification effect of the harmful gas is also reduced.

On the other hand, in the case of the present invention, by forming the size of the cross section of the injection hole 131 in a form that gradually expands by performing the injection chamber 100, foreign substances are fixed in the injection hole 131 to block the injection hole 131. Can be prevented. That is, when a foreign substance is inserted into the injection hole 131, the size of the injection hole 131 increases afterwards, so that the foreign substance cannot be fixed inside the injection hole 131.

The pretreatment tank 200 stores washing water, and an injection chamber 100 is installed at the top. In addition, gas and washing water are received from the injection chamber 100 through the supply pipe 110.

As shown in FIG. 1, the pretreatment tank 200 is separated from the washing water tank 400 by a barrier wall 210. In addition, a partition wall 220 is installed in the pretreatment tank 200 in proximity to the blocking wall 210. The partition wall 220 has an upper opening 221 formed at an upper portion and a lower opening 222 formed at the lower portion of the partition wall 220. The gas introduced into the pretreatment tank 200 passes through the upper opening 221, and the washing water passes through the lower opening 222.

Meanwhile, the supply pipe 110 inserted into the pretreatment tank 200 is opened to face in a direction opposite to the direction in which the partition wall 220 is located. That is, the lower end of the supply pipe 110 is manufactured in an obliquely cut form with respect to the water surface of the pretreatment tank 200, and the gas discharged through the lower end of the supply pipe 110 collides with the surface of the washing water and forms a turbulent flow. The stagnation time in the pretreatment tank 200 is increased according to the turbulent flow of.

That is, since the gas flowing into the pretreatment tank 200 through the supply pipe 110 is discharged farthest from the upper opening 221 in the opposite direction to the direction in which the upper opening 221 is located, it is discharged from the supply pipe 110 and is discharged from the upper opening ( The flow distance increases before moving to 221). In addition, the flow direction of the gas flowing into the pretreatment tank 200 through the supply pipe 110 changes to move to the upper opening 221, and thereafter, turbulent flow with an uneven flow shape in the process of colliding with the supply pipe 110 Will form. Accordingly, it is possible to increase the time for the noxious gas such as ammonia to contact the washing water and increase the absorption rate of the noxious gas of the washing water.

The defoaming pump 300 supplies the washing water stored in the pretreatment tank 200 to the spray nozzle 120 to circulate the washing water. That is, the defoaming pump 300 supplies washing water to the injection nozzle 120, and the washing water sprayed into the injection chamber 100 through the injection nozzle 120 absorbs harmful gases such as ammonia and foreign substances such as dust. After being mixed with the washing water stored in the pretreatment tank 200, the defoaming pump 300 supplies washing water containing harmful gases and foreign substances to the spray nozzle 120 again. At this time, it is preferable that the pipe connecting the defoaming pump 300 and the pretreatment tank 200 is connected to an upper portion of the pretreatment tank 200 to minimize suction of foreign substances.

In addition, a pressure gauge (not shown) may be installed in a pipe connecting the injection nozzle 120 and the defoaming pump 300. The pressure gauge measures the pressure change of the pipe connecting the spray nozzle 120 and the defoaming pump 300, so that the operator can know when to wash or replace the nozzle cap 130. As described above, the nozzle cap 130 may be separated or replaced from the spray nozzle 120.

The washing water tank 400 stores washing water, and an outlet 401 through which deodorizing gas is discharged is formed at the top. As described above, the washing water tank 400 is separated from the pretreatment tank 200 by the barrier wall 210, and a passage 211 connecting the pretreatment tank 200 and the washing water tank 400 to the barrier wall 210 Is formed. The gas of the pretreatment tank 200 and the washing water stored in the washing water tank 400 are exchanged with each other through the passage 211. That is, gas and washing water are moved through one passage 211, and the washing water of the washing water tank 400 is transferred to the pretreatment tank 200, and the gas in the pretreatment tank 200 is transferred to the washing tank 400. do. The water level of the pretreatment tank 200 must be maintained lower than the height of the passage 211. As the washing water and the gas are interchanged through one passage 211 in this way, the gas in the pretreatment tank 200 follows the surface of the washing water according to the level of the washing water stored in the washing water tank 400. It is introduced into the washing water tank 400 to increase the absorption rate of ammonia by the washing water.

The gas flowing into the injection chamber 100 and the pretreatment tank 200 first undergoes a process of treating harmful gases and foreign substances, and the second harmful gases and foreign substances are processed in the washing tank 400, thereby preventing the remaining harmful gases. And remove foreign substances. Accordingly, the washing water in the washing water tank 400 is relatively clean compared to the washing water in the pretreatment tank 200, and by supplying the washing water to the pretreatment tank 200, harmful gases and foreign substances can be efficiently treated. In addition, as the ammonia is dissolved in the washing water, the washing water becomes alkaline, and the washing water in the washing water tank 400 has a lower alkali concentration than the washing water in the pretreatment tank 200. That is, the washing water of the washing water tank 400 is closer to the neutral pH of the pretreatment tank 200 compared to the washing water. Accordingly, the washing water in the washing water tank 400 may be mixed with the washing water in the pretreatment tank 200 to lower the PH concentration.

The washing tank 400 and the pretreatment tank 200 are provided with a viewing window 601 through which an operator can check the level of the stored washing water.

In addition, a washing water nozzle 410 for spraying washing water is installed in the washing water tank 400. In addition, a polling 602 is installed under the washing water nozzle 410 in the washing water tank 400. The polling 602 reduces the flow rate of the gas in the process of discharging the gas flowing into the washing water tank 400 through the passage 211 through the discharge port 401, thereby reducing the flow rate of the washing water sprayed through the washing water nozzle 410 and It is possible to increase the contact time of and improve the removal effect of the harmful gas by allowing the harmful gas not removed in the pretreatment tank 200 to be absorbed into the washing water. In addition, a demister 420 is installed in the washing tank 400 to remove moisture from the deodorizing gas discharged through the outlet 401.

The washing water pump 500 supplies the washing water from the washing water tank 400 to the washing water nozzle 410 to circulate the washing water.

In addition, a water level controller 700 is installed in the washing water tank 400. As shown in Fig. 3(a), a flange coupling part 603 protruding outward is formed in the washing water tank 400, and a water level regulator 700 is installed in the flange coupling part 603.

Specifically, the water level controller 700 includes a flange portion 710, a position control portion 720, a washing water supply valve 730, and a ball top 740. The flange portion 710 is attached to the outer wall of the washing water tank 400. That is, the flange portion 710 is coupled to the flange coupling portion 603 protruding outward of the washing water tank 400. And the through hole 711 is formed in the flange portion 710. The position control part 720 is coupled to the flange part 710 to block the through hole 711. And the washing water supply valve 730 is mounted in the center of the position control unit 720 to supply the washing water to the washing water tank 400 through the through hole 711, and the ball top 740 is The washing water supply valve 730 is opened and closed according to the water level.

As shown in FIG. 3(b), long vertical holes 721 are formed in the upper and lower portions of the washing water supply valve 730 in the position control unit 720. And the position control part 720 and the flange part 710 are coupled to each other by a coupling member 750 inserted into the long hole 721. In the embodiment of the present invention, the coupling member 750 is a bolt protruding from the flange portion 710 and a butterfly nut coupled with the bolt. That is, the bolt protruding from the flange portion 710 is inserted into the long hole 721, and the upper and lower positions of the position control unit 720 can be adjusted in a state in which the bolt and the butterfly nut are loosely coupled. In this way, the height of the ball top 740 can be adjusted by adjusting the vertical position of the position control unit 720. Accordingly, when the washing water is consumed at a high speed due to evaporation of the washing water, the ball tower 740 is raised so that more washing water is supplied above a certain level of the washing water tank 400, and in the opposite case, the ball tower 740 is It can be lowered so that the supply of rinse water is cut off at a lower level.

And, as shown in Figure 1, the washing water tank 400 may be installed a deodorant liquid spray nozzle 430. The deodorizing liquid spraying nozzle 430 is connected to the deodorizing liquid dilution tank 440 and sprays the deodorizing liquid into the washing water tank 400. If the gas to be treated contains a large amount of ammonia and has a strong odor, the harmful gas is not completely treated by the treatment through the injection chamber 100, the pretreatment tank 200, and the washing water tank 400 as described above. It may not be possible. In this case, the harmful gas can be completely removed by additionally spraying the deodorizing liquid. In the first embodiment, since the main purpose is to remove ammonia, which is the main cause of odor, the deodorant spray nozzle 430 sprays an acidic solution to neutralize alkaline ammonia.
