Description

[0001] The present invention relates to a deodorizer provided with a bypass,

The present invention relates to a deodorizing device for removing odors generated from places such as a manure treatment plant, an animal husbandry facility, and a sewage treatment plant, and more particularly, to a deodorizing apparatus for collecting odor-containing gas from wastewater or a material generating odor, A deodorizing tower having a venturi pipe; A spray nozzle for spraying a deodorant in a mist state to a malodorous gas introduced through the venturi tube; A bypass pipe for collecting the purified gas discharged from the deodorization tower and re-supplying it to the deodorization tower; An odor sensor provided at an outlet of the deodorizing tower; A bypass blower for providing a suction force to the bypass pipe; A bypass valve for opening and closing the bypass pipe; And a bypass controller for controlling the odor sensor, the bypass blower and the bypass valve; When the odor sensor for detecting the gas discharged from the deodorizing tower senses an odor of a predetermined value or more, the bypass controller opens the bypass valve, operates the bypass blower, re-supplies the discharged gas to the deodorization tower, The deodorizing device being provided with a bypass conduit.

A method has been used in which a gas containing odor is collected from a place where a conventional odor is generated and treated in a deodorization tower to generate a purifying gas from which the offensive odor has been removed.

In this method, a plurality of nozzles are provided in the deodorization tower, and water is sprayed onto the gas containing the odor introduced into the deodorization tower from the deodorization tower to remove the odor (scrub method). In the deodorization tower, activated carbon, silica gel, A method in which an adsorbent layer such as zeolite is disposed to adsorb a malodorous substance (activated carbon adsorption method), or a method in which a microorganism layer is disposed in place of the adsorbent as described above to cause the microorganism to decompose odor generating substances ).

In such a conventional deodorization method, generally, a flushing nozzle, an adsorbent layer or a microorganism layer is disposed in the middle or upper part of the deodorization tower, and a gas containing odor is introduced from the bottom of the deodorization tower, The deodorizing reaction is caused to come into contact with the adsorbent layer or the microbial layer or the deodorized gas is discharged to the upper portion of the deodorizing tower by spraying water onto the odor-containing gas through the water-washing nozzle.

In the case of the conventional method of deodorization as described above, it is easy to maintain and manage the deodorization method, and there is no problem of secondary contamination due to chemical substances by using no chemicals, It is possible to simultaneously remove mist and dust (dust particles: particulate matter having a size of 1 to 100 mu m) which are referred to as air pollutants. However, since the water-washing method can remove only water-soluble substances from malodorous components, it can not be expected to exert an effect on substances having low solubility in water such as hydrogen sulfide, mercaptans, higher amines and fatty acids, 30% or less.

On the other hand, in the case of the activated carbon adsorption method, since the odorous substance is adsorbed and removed by the intermolecular attraction force using the adsorbent material such as activated carbon, silica gel, zeolite, etc., it is effective for removing alcohol, benzene, fatty acids, mercaptans, However, the activated carbon adsorption method has a disadvantage in that it is less effective for ammonia, amine, and aldehyde, and is not economical because the price of adsorbent such as activated carbon is high. In the case of activated carbon adsorption method, deodorization efficiency is relatively high as 90% or less.

Since the microbial contact method does not use chemical substances as in the water washing method, there is no fear of secondary contamination, but it is disadvantageous in that it is difficult to maintain microbes under proper conditions and the deodorization efficiency is also very low at 40% or less . In the case of the microbial contact method or the activated carbon adsorption method, the microbial or activated carbon should be periodically replaced after a certain period of use, which is difficult and economically expensive.

As described above, the conventional odor removal method has disadvantages of each, and the deodorization efficiency is relatively low, at most 90%. The deodorization effect on ammonia, amine, and aldehyde is low and the activated carbon must be replaced at regular intervals even in the method of relatively high deodorization efficiency as in the activated carbon adsorption method, which is a relatively uneconomical problem.

The most important point in deodorization and removal is deodorization efficiency. Therefore, there is a demand for a new deodorizing device and a deodorizing method using the deodorizing device that can economically achieve high deodorization efficiency of 90% or more.

As a prior art related thereto, a deodorizing device of the Korean Utility Model Registration No. 20-0236730 (Jun. 21, 2011) has been posted.

The present invention relates to a deodorization tower (10) having a venturi pipe (11) for collecting a malodorous gas from wastewater or a substance generating a bad smell and introducing it into the inside; An injection nozzle (12) for injecting a deodorant in a mist state into a malodorous gas introduced through the venturi pipe; A wastewater passage 14 for collecting the purified gas discharged from the deodorization tower and re-supplying it to the deodorization tower; An odor sensor (15) provided at an outlet of the deodorizing tower; A bypass blower (16) for providing a suction force to the bypass pipe; A bypass valve (17) for opening and closing the bypass pipe; And a detour controller (18) for controlling the odor sensor, the detour blower and the detour valve. When the odor sensor (15) detecting the gas discharged from the deodorizer tower (10) (18) opens the bypass valve (17) and activates the bypass blower (16) to return the gas to the deodorization tower for deodorization.

In the deodorization apparatus, the venturi pipe 11 is preferably provided through one side wall of the upper end of the deodorization tower 10 to introduce the malodorous gas into the deodorization tower. More preferably, the venturi pipe 11 is fitted in the upper part of the deodorizing tower 10 and is bent downwardly to extend downward. Therefore, the malodorous gas is introduced from the outside of the deodorization tower 10 and guided downward of the deodorization tower.

On the other hand, in the deodorizing apparatus, the injection nozzle 12 for spraying the deodorant in a mist state is connected to the concave portion of the venturi tube around the concave portion of the venturi tube 11. [ Thus, as the malodorous gas passes through the recess of the venturi tube, it comes into contact with small deodorant particles such as mist droplets which are ejected from the injection nozzle when the flow rate is increased. Thereafter, the malodorous gas contacted with the deodorant is dispersed in the deodorization tower while being uniformly mixed in the venturi tube. Therefore, the inside of the deodorizing tower is filled with the mist of the odor containing gas in contact with the deodorant.

As described above, the injection nozzle 12 is connected to the concave portion of the venturi tube 11. Accordingly, the position of the mist spray nozzle varies depending on the position and shape of the venturi pipe inserted into the deodorizing tower.

On the other hand, as in the above preferred embodiment, when the gas is inserted into the upper portion and then bent into the '┓' shape and extended downwardly of the deodorization tower, the malodorous gas is dispersed below the deodorization tower after contacting with the deodorant in the venturi tube. The malodorous gas dispersed in the downward direction of the deodorization tower is circulated back upwards through the upper portion of the deodorization tower and discharged to the outside through the upper portion of the deodorization tower while the odor component is removed due to contact with the deodorant.

According to a preferred embodiment of the present invention, the present invention may be applied to a deodorization tower comprising: a waste-water pipe line 14 for collecting purified water discharged from the deodorization tower and re-supplying it to the deodorization tower; An odor sensor (15) provided at an outlet of the deodorizing tower; A bypass blower (16) for providing a suction force to the bypass pipe; A bypass valve (17) for opening and closing the bypass pipe; And a bypass controller (18) for controlling the odor sensor, the bypass blower and the bypass valve.

The waste gas pipe 14 selectively collects the gas discharged from the deodorizing tower and supplies it to the deodorization tower. That is, one end of the right-side hollow tube 14 communicates with the outlet of the deodorizing tower, and the other end of the right-side hollow tube 14 communicates with the front of the concave portion of the venturi tube.

Further, a bypass injection nozzle 141 for spraying the bypassed gas, which is disposed in parallel to the venturi pipe in front of the concave portion of the venturi pipe 11, is additionally provided at the end of the right pipe duct 14, Containing gas introduced into the venturi pipe and the gas discharged through the bypass pipe are preferably introduced together into the venturi pipe.

The odor sensor 15 detects the odor concentration of the gas discharged after being purified in the deodorizing tower.

The bypass blower 16 provides a suction force to the bypass pipe so that the gas discharged from the deodorization tower flows into the bypass pipe.

Therefore, when the odor sensor 15 sensing the gas discharged from the deodorizing tower 10 senses the odor of a predetermined value or more, the bypass controller 18 opens the bypass valve 17 and operates the bypass blower 16 So that the deodorizing effect can be increased by deodorizing the discharged gas into the deodorization tower.

In addition, the bypass controller 18 of the present invention is configured such that, when the bypass conduit is opened, the odor-containing gas collected from the wastewater or the material generating the odor is introduced into the venturi tube so that the gas discharged from the deodorization tower can be easily re- So that the pressure is reduced by the pressure provided by the bypass blower.

The venturi pipe 11 may further include a guide pipe 19 having a plurality of guide vanes 191 on the inner side thereof so that the malodorous gas introduced into the venturi pipe rotates and is injected from the injection nozzle It is preferable to be mixed with a deodorant.

The guiding tube 19 is provided with a guide vane 191 on its inner side so that the malodorous gas introduced into the venturi tube 11 passes through the recess while rotating in a spiral manner, So that the deodorizing efficiency is increased because the deodorant particles are uniformly mixed with the deodorant particles sprayed from the jetting nozzle 12.

The deodorization tower 10 is further provided with a filling part 13 for receiving one or more fillers in plastic, shells, wood pieces and stones, and the gas discharged down through the venturi pipe is filled in the filling part 13 ), And the deodorant component is adsorbed to the charging part and the gas is discharged to the outside of the deodorizing tower.

The filling part may be filled with a filler made of plastic, shell, stone, wood, or the like. These fillers are generally made of a porous material so that deodorant materials sprayed in a misty state in the porous holes are adsorbed.

According to a preferred embodiment of the present invention, the malodor-containing gas introduced and dispersed from above the deodorizing tower through the venturi tube to the lower part of the deodorization tower is, as described above, So that the deodorizing agent can be contacted again with the deodorant adsorbed on the filler in the filling part while rising to the upper side of the deodorization tower. Thus, the deodorization efficiency in the deodorization tower can be maximized.

The kind of the filler and the form of the filling part can be the same as those used in a conventional deodorizing device, that is, a deodorizing device using a washing method, an activated carbon adsorption method, a microbial contacting method, or the like.

In the deodorizing apparatus of the present invention, the deodorant may include an oxidizing agent such as hydrogen peroxide (H 2 O 2 ) and ozone (O 3 ), a mixture of water and vinegar, a disinfectant, and a microbial enzyme preparation. Of these, microbial enzyme preparations are most preferred. The microbial enzyme preparation is made by mixing microbial enzyme with surfactant and water. It is natural-friendly, biodegradable in water and has no secondary pollution and high deodorization efficiency.

The deodorants are preferably housed in separate deodorant tanks in the deodorizing apparatus of the present invention. These deodorants are diluted by water or the like in a certain proportion in a deodorant tank, and are sent from the tank to the injection nozzle at a constant pressure by a pump or the like to be sprayed in a mist state. The deodorant sprayed in the mist state is contacted with the odor containing gas introduced into the deodorization tower to remove the odor.

In the deodorization apparatus, the fan collects the odor-containing gas from the wastewater or solid matter generating odor, and sends the odor-containing gas to the deodorization tower through a pipe or the like not shown. The deodorization tower deodorizes the introduced malodor-containing gas and discharges the purified gas out through the top of the deodorization tower. A venturi pipe (11) is connected to one side of the top of the deodorization tower, which is inserted into the deodorization tower through the deodorization tower from the outside of the deodorization tower and bent downwardly and then downwardly along the longitudinal direction of the deodorization tower. A spray nozzle (12) is connected to the concave portion of the venturi pipe (11). The venturi pipe 11 introduces the collected odor-containing gas into the deodorization tower 10, and a plurality of injection nozzles 12 provided in the concavity of the venturi pipe 11 mixes the odor-containing gas introduced through the venturi pipe 11 with mist . As a result, small deodorant particles such as fog droplets come into contact with the odor-containing gas, and the flow rate of the fluid at the concave portion of the venturi tube becomes faster, so that odor-containing gas particles mixed with the deodorant are mixed at a high speed .

The deodorization tower (10) has a filling portion (13) for accommodating a filler in its middle portion. The malodorous gas mixed with the deodorant through the venturi pipe (11) and introduced below the deodorization tower descends below the deodorization tower and then circulates upward again. At this time, the odor-containing gas passes through the filling part (13) and comes into contact once again with the deodorant adsorbed on the filler.

The deodorant is accommodated in a separate deodorant tank outside the deodorization tower 10 and diluted with water at a suitable ratio. The diluted deodorant is adjusted to a suitable pressure by the pump and the pressure regulating tank and is supplied to the injection nozzle 12 in the deodorization tower 10 through a pipe not shown. As described above, since the deodorant is stored in a separate deodorant storage tank, it can be easily supplemented if necessary.

The injection nozzle 12 protrudes from the inside of the pipe annularly connected around the concave portion of the venturi tube 11 to the concave portion and is connected to the concave portion and can be installed at one or more appropriate number have. The nozzle and the annular pipe from which the nozzle extends are connected to the end of the pipe for transporting the deodorant from the deodorant storage tank on the outside of the deodorization tower 10.

As described above, the deodorizing apparatus according to the preferred embodiment of the present invention can provide a new deodorizing apparatus which is easier to maintain, easier to deodorize, and more economical than the conventional deodorizing apparatus.

The present invention is not limited to the above embodiments and modifications, and can be modified or modified by those skilled in the art.
