Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an organic waste treatment apparatus capable of reducing the amount quickly and easily by subjecting organic waste such as straw (garbage) to fermentation decomposition treatment with microorganisms, and malodor generated during the fermentation decomposition treatment. The present invention relates to an improved deodorizing apparatus that simply deodorizes without exhausting gas directly to the outside.
[0002]
[Prior art]
Today, the generation amount of organic waste including garbage (garbage) discharged from ordinary households and restaurants is increasing year by year, especially when it is stored at home until the date of garbage collection or the bad smell at the collection place. The early disposal of moths has become a major social problem, such as the occurrence of pests such as frogs and flies, and the spread of moths by mischief of wild dogs and crows.
[0003]
And most of the above-mentioned wastes were incinerated together with other garbage at a cleaning plant or the like, or were processed by a landfill system or the like. In the incineration method, raw garbage is incinerated with other waste as it is, so there are difficulties in the installation location of the equipment in consideration of smoke emission, odor, etc.In the landfill method, the landfill site There were various problems such as how to deal with odor, generation of pathogenic bacteria, etc. as well as ensuring.
[0004]
For this reason, today, the aerobic fermentation treatment of organic waste, that is, the processing technology related to composting (composting) enables not only pollution-free processing but also waste recycling technology and natural processing. It has been reviewed as a technology. In particular, with regard to food waste called unprocessed rice, the livestock industry that has consumed this in large quantities has now been replaced with a blended feed, so that it is quick to solve the organic waste treatment, and Therefore, the development of a processing apparatus capable of highly decomposing, fermenting and reducing the amount is desired at an early stage.
[0005]
The treatment of koji, which is generally well known today, is almost achieved by, for example, subjecting organic components in garbage to fermentation decomposition treatment with the help of microorganisms such as medium temperature and high temperature bacteria. Fermentation decomposition treatment of the above-mentioned garbage is not only that the fermentation heat generated during the fermentation treatment contributes greatly, but also that there is relatively little malodorous gas generated during the fermentation treatment, and fermentation using aerobic microorganisms The decomposition method is widely used today.
[0006]
In order to activate the aerobic fermentation treatment, it is necessary to maintain an environment in which the activity of microorganisms is kept good. Therefore, it is necessary to maintain an appropriate processing amount of the koji to be fermented and moisture and temperature suitable for the fermentation treatment. In addition, fresh oxygen (air) must always be supplied in order to grow and activate microorganisms.
[0007]
As a result, in the apparatus for treating the soot, generally, the stirring means for uniformizing the moisture state and the oxygen supply state of the whole treated product such as soot and a moisture adjusting agent, the activation of the microorganisms and the moisture at a constant value. It is equipped with aeration (aeration) means for maintaining the heating and heating means for promoting fermentation and decomposition of koji, and always maintains a state suitable for aerobic fermentation treatment of koji in the fermentation tank, It is comprised so that the fermentation decomposition process of a koji can be accelerated | stimulated.
[0008]
However, in the above fermentation process, oxygen is constantly fed from the bottom of the fermentation tank into the tank for the activation of microorganisms and the water content of the fermented product to be maintained at a constant value, and passes through the fermentation tank. Since the odor gas generated by the fermentation process is directly discharged to the outside together with the substances containing odors, the odors are scattered to the living environment. It will cause a lot of bad effects.
[0009]
[Problems to be solved by the invention]
For this reason, a deodorizing device is attached to the fermentation treatment tank, and efforts are made to eliminate damage caused by bad odor. As a deodorizing apparatus that is well known today, for example, malodorous gas is brought into contact with and adsorbed to an adsorption deodorant using activated carbon to deodorize odors. However, since malodorous gas contains a lot of various malodorous components (ammonia gas, methane gas, etc.), if these gases are brought into direct contact with activated carbon, the adsorption load of the malodorous component increases and the activated carbon deteriorates early. The activated carbon absorbs moisture more than necessary due to the moisture containing malodor that is generated at the same time as the malodorous gas, and the deodorizing effect is significantly reduced.
[0010]
Instead of the above-mentioned deodorizing treatment with activated carbon, a method of deodorizing malodorous gas to an allowable concentration by supplying ozone to a deodorizing apparatus has been developed. In this deodorization treatment by supplying ozone, for example, a deodorizing apparatus including, for example, an ozone generating apparatus, and a method of deodorizing by mixing ozone and malodorous gas has been mainly developed. In this case, in order to reduce the malodorous component in the malodorous gas, it is necessary to increase the supply amount of ozone according to the degree of the malodorous component. However, increasing the amount of ozone supplied increases the size of the ozone generator and makes the device itself expensive, and if ozone itself flows out of the device as it is, it may adversely affect the human body. Usually, since a catalyst for decomposing ozone itself into oxygen was specially needed, this deodorizing means by ozone would be very expensive and inevitably increase the cost of this kind of organic waste treatment apparatus itself. There was a problem.
[0011]
In view of the above-mentioned various problems, the present invention is an organic waste treatment apparatus that has a simple structure for deodorizing odors such as malodorous gas and water vapor generated during fermentation of koji quickly and favorably and is easy to maintain. An object of the present invention is to provide a deodorizing apparatus.
[0012]
[Means for Solving the Problems]
  In order to achieve the above object, the present invention provides a deodorizing apparatus for an organic waste treatment apparatus according to claim 1, wherein the organic waste is a fermentation apparatus for decomposing solid organic waste by decomposition with aerobic microorganisms. At the tip of the exhaust pipe that communicates with the waste treatment tank that ferments the product,A small amount of resin-made small-diameter spheres are bonded to each other and molded into a bottomed cylindrical shape with a minute number of irregularly spaced gaps.The attached odor gas discharge cylinder and the mist gas are immersed in the water and water containing odor gas and odor components is submerged in the water.ExcretionLet me outOdor components contained in malodorous gasAt the top of the aeration tank section to be primary treated and this aeration tank sectionBuilt-in odor moving speed suppression device configured by housing a number of hollow spheres that disperse odor exhausted from the aeration tank section and suppress the moving speed in a housing.Filled with an air layer and a deodorant that physically adsorbs odors leaking from the aeration tank through this air layer.TheA deodorant containing tank part for deodorizing the odor by secondary treatment, and further, the aeration tank partandThe deodorant storage tank part is formed integrally with one container through the air layer inside.It is characterized by that.
[0013]
  The deodorization apparatus in the organic waste treatment apparatus according to claim 2 is the deodorization apparatus according to claim 1,The deodorant storage tank unit is configured by laminating a plurality of casings filled with a deodorizing agent, and accommodating each casing so as to be able to be put in and out individually, and further, the casings in a plurality of stages. In addition, the container accommodated so as to be able to be taken in and out is configured by attaching an exhaust hood whose upper end is opened and whose exhaust port is closed with a breathable covering member having a fine mesh. Features.
[0017]
In the present invention, the malodorous gas such as ammonia produced by the decomposition of most of the soot into ammonia, methane gas, carbon dioxide gas and water by fermentation decomposition treatment of microorganisms is caused by contact with water in the aeration tank section. The primary treatment that dissolves and removes most of the part, and the primary treated odor is further sent to the deodorant storage tank and secondarily treated with the deodorant for deodorization. Deodorizing treatment can be performed quickly and reliably with a simple configuration.
[0018]
Further, in the primary treatment of malodorous gas, the malodorous gas is added by a bottomed cylindrical diffuser cylinder formed such that a large number of small spheres made of resin are pressure-bonded to form a predetermined number of small gaps. Since it is configured to be jetted into the water of the aeration tank unit in a pressurized state, malodorous gas is slowly ejected in small amounts into the water of the aeration tank unit, so that the tank unit is in good contact with the water. As a result of being obtained and discharged into water in small amounts, dissolution / removal with water is facilitated, and malodorous components can be efficiently deodorized.
[0019]
Furthermore, since the deodorizer can adsorb and deodorize the odor that has become diluted by passing through the water in the aeration tank, the deodorizer can be less contaminated, and the primary treatment of the malodorous gas can be performed at low cost. In combination with this, the running cost of the deodorizing process can be significantly reduced. In addition, when replacing the deodorant, the housing containing the deodorant is configured to be able to be taken in and out from the deodorant storage tank part, so that the replacement of the deodorant does not stop the deodorizer, It is convenient because it can be done quickly and easily.
[0020]

The agitation blade 20 is attached as described above so that the agitation can be moved in the length direction of the treatment tank 1 when the agitation is agitated.
[0027]
Next, the heating means 3 will be described. As shown in FIG. 1, the heating means 3 is located at the middle position of the processing tank 1 (position of the middle part of the height dimension) from the bottom surface of the lower part of the processing tank 1 which is bent in a semicircular shape (U shape). It is made of a material with excellent elasticity, such as heat-resistant rubber, which has an electric heater (not shown) that is extended and pasted, and always ferments the koji by controlling the inside of the processing tank 1 to a predetermined temperature. Make it effective. Reference numeral 3a denotes a temperature controller that cuts off the power to the heater when the temperature of the processing tank 1 reaches a predetermined temperature (for example, about 40 ° C.), and is connected to the control device 7.
[0028]
As shown in FIGS. 1 and 2, the air feeding means 4 feeds air near the bottom surface in the treatment tank 1, for example, at a constant pressure, and supplies oxygen to a group of microorganisms in the bacterial bed mixed with soot. In this example, as shown in FIG. 2, an electric air supply blower (blower) 21 and a discharge port and a base end (not shown) of the blower 21 are provided. It is comprised by the feed pipes 22 and 23 which connect and feed the air in the processing tank 1. FIG.
[0029]
And each front-end | tip of the said feed pipes 22 and 23 is attached to the lower part of the side wall of the processing tank 1, respectively by welding etc., and the attachment site | part of the side wall of the processing tank 1 to which the front-end | tip of each feed pipe 22 and 23 is attached As shown in FIGS. 1 and 3, a predetermined number of through holes 24 a that form a feed port 24 for feeding air into the treatment tank 1 are perforated. The pressure of the air supplied to the through-hole 24a is supplied to the treatment tank 1 to obtain a pressure at which soot or the like does not leak from the through-hole 24a into the feed pipes 22 and 23 during stirring. Therefore, it is possible to feed fresh air constantly into the treatment tank 1 to promote the activity / reproduction of the microorganism group and to perform the fermentation process of koji smoothly and satisfactorily. In addition, 23a in FIG. 1 is an on-off valve that varies the amount of air supplied to the processing tank 1.
[0030]
Next, the air discharge means 5 will be described. As shown in FIGS. 1 and 2, the air discharge means 5 includes an exhaust port 25 perforated on the rear side (left direction in FIG. 1) of the processing tank 1 (upper side), and a processing tank from the exhaust port 25. 1 between the exhaust port 25 and the air discharge blower 26, and the air discharge blower (blower) 26 that forcibly sucks and discharges malodorous gas generated in the fermentation process in 1 and water vapor containing bad smell, etc. The exhaust gas odor gas and the like are deodorized to eliminate odors, and the exhaust gas pipes 28 and 29 are connected between the blower 26 and a deodorizer 27 which will be described later.
[0031]
The air discharge means 5 sends malodorous gas generated during fermentation of koji to the deodorizing device 27 together with air that is fed into the treatment tank 1 and promotes the activity and propagation of microorganisms. This is for deodorizing the gas and releasing it into the atmosphere. By constantly sucking malodorous gas such as moisture and ammonia in the treatment tank 1, when the lid 10 is opened and closed, the malodor is generated from the inlet 9. Good prevention from direct release into the atmosphere. In particular, when the fermentation decomposition treatment of koji is near the end, a considerable amount of malodorous gas is generated in the treatment tank 1. In this case, the flow rate adjustment opening / closing provided in the middle of the supply pipes 22 and 23 is performed. For example, by narrowing the valve 23a, the inside of the processing tank 1 is maintained at a negative pressure, for example, 1 atm or less, and the evacuation gas is forcibly discharged by the air discharging means 5 in order to avoid leakage of malodorous gas from the processing tank 1. By doing so, it is possible to prevent the malodorous gas from naturally leaking outside from the inlet 9 and the outlet 11.
[0032]
The sprinkling means 6 is installed to adjust the temperature in the processing tank 1 and the moisture content such as soot. As shown in FIG. The watering nozzle 30, the watering pipe 31 connecting the watering nozzle 30 and a water supply source (not shown) such as a water heater, and an open / close valve 32 attached to the water supply pipe 31. By spraying water regularly, the watering nozzle 30 favorably prevents the moisture content such as soot from being lowered or the inside of the processing tank 1 from being dried.
[0033]
Next, the structure of the deodorizing apparatus 27 of the present invention that deodorizes the malodorous gas generated during the fermentation decomposition process such as koji in the processing tank 1 will be described with reference to FIGS.
[0034]
In FIG. 6, the deodorizing device 27 of the present invention deodorizes an aeration tank unit 41 that primarily performs malodorous gas and a secondary process of the odor that is located above the aeration tank unit 41 and that has been primarily treated. It is configured using a single container 40 having a deodorant storage tank unit 51.
[0035]
First, the configuration of the aeration tank unit 41 in the container 40 will be described. In FIG. 7, the aeration tank section 41 accommodates a bottomed cylindrical diffused cylinder 42 connected to the tip of an exhaust pipe 29 connected to the blower 26 in the vicinity of the bottom, and a water supply pipe connected to a water supply source 43 at the top. 44 is connected to a pipe via a water supply valve 45, and further includes a water level gauge 46 which is fixed to the upper surface of the aeration tank unit 41 and hangs down the detection unit to the vicinity of the bottom of the aeration tank unit 41. A drain pipe 47 is connected to the aeration tank 41 at a position opposite to the exhaust pipe 29 via a drain valve 48 at a position on the same horizontal line as 42.
[0036]
The water supply valve 45 and the drain valve 48 attached to the feed pipe 44 and the drain pipe 47 are periodically opened and closed by a command signal so that the water in the aeration tank 41 can be supplied and drained. In addition, the water level gauge 46 can send a detection signal of the lowest and highest water levels in the aeration tank unit 41 to the control device 7 and send an opening / closing command to the water supply / drainage valves 45, 48. It is connected to the control device 7. For example, when the time for draining the water in the aeration tank unit 41 is reached, the drain valve 48 is opened by a command signal from the control device 7 to quantitatively drain the water in the aeration tank unit 41 and then the drain valve 48 is closed. . Thereafter, the water supply valve 45 is opened by a command signal from the control device 7, water is supplied to the aeration tank unit 41 from the water supply source 43 through the water supply pipe 44, and it is detected that the water is metered by the water level gauge 46. By closing the water supply valve 45 at the time, the supply / drainage of the aeration tank unit 41 is completed.
[0037]
In addition, the diffuser cylinder 42 arranged near the bottom of the aeration tank unit 41 is, for example, in a space between the inner and outer walls of a mold in which a small spherical sphere 42a made of resin is formed into a bottomed cylindrical double tube wall shape. The required amount is filled, and in this state, the sphere 42a is pressurized at a predetermined pressure, the mold is heated to a predetermined temperature, and the spheres 42a filled in the mold are partially welded to each other to reduce the diameter. It is formed by fixing the necessary number of spherical bodies 42a integrally and molding the bottomed cylindrical dispersion cylinder 42.
[0038]
When the dust cylinder 42 is molded as described above using a small-diameter sphere 42a, the sphere 42a portion is deformed by heating and the spheres 42a adhere to each other. In this case, if the mold is heated to such an extent that the original shape of the sphere 42a is broken, the sphere 42a cannot be melted and remain in the original shape, but if heated to such an extent that the original shape is retained, the spheres 42a adhere to each other, but are partially bonded. Therefore, as shown in FIG. 8, a minute gap a through which air and moisture circulate is generated at a portion where the bonding is not performed.
[0039]
The fine gaps a can hardly be formed regularly, and a predetermined number of the fine gaps a are irregularly scattered in the entire cylindrical cylinder 42 formed and processed into a bottomed cylindrical shape. Needless to say, the size of the fine gap a to be formed varies. In addition, since the diffusion cylinder 42 formed as described above has an appropriate number of fine gaps a through which air flows, it can be easily immersed in the water of the aeration tank section 41.
[0040]
In addition, since the fine gaps a through which air flows are irregularly formed with an appropriate number of different sizes, for example, when air is sent to the scattering cylinder 42, the air is fine. Since the location and size of a are irregular, they do not flow out as they are, but are temporarily accumulated in the scattering cylinder 42 and gradually discharged into the water through the fine gap a. That is, it is configured so that the fed gas or fluid can be gradually discharged without being discharged at once.
[0041]
Next, as shown in FIG. 7, the configuration of the deodorant storage tank unit 51 that performs secondary processing of malodorous gas (odor) that is integrally provided via the air layer 49 on the upper part of the aeration tank unit 41 will be described. . As shown in FIG. 7, for example, as shown in FIG. 7, the tank unit 51 includes three casings 52, 53, and 54 each having a fine mesh net 55 stretched on the bottom surface and stacked in a stepped manner. And the housings 52 to 54 are individually housed and placed so that they can be taken in and out of the tank portion 51 like drawers.
[0042]
And each said housing | casing 52-54 is filled with the deodorizing agents 56, such as activated carbon which carries out the secondary process of each odor in each housing | casing part, and deodorizes, and inserts in the said deodorizing agent storage tank part 51, The said tank part By being detachably mounted on the mounting portion b of each step portion provided on the side wall 51, as shown in FIG. 7, it is accommodated and held in a state of being mounted on a plurality of steps. A handle 57 is attached to each of the casings 52 to 54 on a front wall surface (in the same direction as the drain pipe 47) that is a drawing direction of the casings 52 to 54, respectively.
[0043]
When the deodorizer 56 is deteriorated or is exchanged due to wet performance deterioration, the casing 52 to 54 is pulled out from the tank portion 51 with the handle 57 and the deodorizer 56 in the casing 52 to 54 is taken out. After that, the casings 52 to 54 are mounted on a predetermined mounting portion b of the tank portion 51 so as to be pulled out, and are pushed to be pushed into the tank portion 51 as they are. Accommodate.
[0044]
Next, the air layer 49 interposed between the aeration tank unit 41 and the deodorant storage tank unit 51 will be described. The air layer 49 is formed in order to prevent the odor of the malodorous gas primarily treated in the aeration tank unit 41 from flowing directly into the deodorant storage tank unit 51, and the configuration is shown in FIG. Thus, for example, a perforated metal (punching metal) in which a large number of flow holes for circulating a fluid are provided in the space above the aeration tank 41 so as to cover the lower surface of the housing 52, for example, A housing 58 bent in a U-shape is attached by suspending the upper open end of the housing 58 on the bottom of the containing agent tank 51.
[0045]
In addition, inside the casing 58, for example, hollow resin hollow spheres (approximately 10 mm immediately after) 59a are accommodated in a stepped manner, and the presence of the hollow spheres 59a prevents the gas flow. The aeration tank unit 41 and the deodorant storage tank unit 51 are partitioned, and as described above, the odor of the first-order malodorous gas is sent to the deodorant storage tank unit 51 over time. Alternatively, the housing 58 for housing the hollow sphere 59a may house the hollow sphere 59a in a bag body, and flatten it horizontally on the air layer 49.
[0046]
In FIGS. 6 and 7, reference numeral 60 denotes an exhaust hood attached to the uppermost opening end of the deodorant storage tank portion 51, and an intrusion prevention film 61 such as a wire mesh for preventing invasion of pests and the like is stretched on the opening portion. Yes.
[0047]
Next, the case where the weight of the koji is reduced by fermentation will be described. First, in the fermentation process of koji, preparations are made in advance for the treatment tank 1 and the fungus bed. That is, for the treatment tank 1, an operation switch (not shown) is turned on, a heater (not shown) of the heating means 3 is energized, and the treatment tank 1 is fermented at an optimum fermentation temperature for activating aerobic fermentation bacteria (microorganism group), for example, , Heated to a temperature of 40 ° C. Thereafter, the opening / closing lid 10 of the treatment tank 1 is opened, and appropriate amounts of inoculum (microorganism group) that forms the fungus bed, nutrients such as rice bran, moisture adjusting material such as sawdust, and pH adjusting agent are mixed together. 9 is put into the treatment tank 1 and left for a certain time (12 to 24 hours) to form a fungus bed.
[0048]
In the case where the fungus bed is formed in advance, as an inoculum, the present invention can be applied to an aerobic thermophilic bacterium (optimum activity temperature of about 10 to 20 ° C., for example, bacteria [Pseudomonas genus]), mesophilic bacteria (optimum activity temperature of about 20 to 40 ° C., for example, Actinomycetes [genus Spreptomyces]), thermophilic bacteria (optimum activity temperature of about 50-60 ° C., for example, Bacillus subtilis [Bacillus]), and anaerobic bacteria (for example, lactic acid bacteria [Bactobacillus sp.) ]) Is suitably blended with the bacteria of the four species, and the inoculum is mixed with other members that form other fungi such as sawdust to form a fungus bed. If the group) is allowed to stand for 12 to 24 hours after completion of the advance preparation, it will breed well and be ready for fermentation of koji.
[0049]
As described above, when the preliminary work before performing the fermentation process of the koji is completed, the koji made of organic waste such as garbage is put into the crushing device 13 and finely crushed. The crushed crushed material is fed as it is to the dehydrating device 14 and subjected to dehydration treatment, and then charged into the processing tank 1 through the charging cylinder 14a. The dewatered sewage is drained as it is.₁Then, it flows into the filtering device 33 and is filtered, and then stored in the water storage tank 34. When the water storage tank 34 is full, the overflowed water is discharged into the sewage as it is. In addition, without using the crushing device 13, the soot may be input as it is by opening the opening / closing lid 10 of the input port 9 of the processing tank 1.
[0050]
When the inlet 9 is opened and the soot is introduced into the processing tank 1, the blower 26 that exhausts the air in the processing tank 1 is driven by a command from the control device 7, and odor is generated from the inlet 9 when the soot is introduced. Suppresses leakage to the outside. When the charging port 9 is closed by the opening / closing lid 10 after the bag is charged, the blower 26 is temporarily stopped.
[0051]
When the addition of the bag is completed, an operation switch (not shown) is turned on. When the operation switch is turned on, the electric motor 18 that rotates the stirring rod 19 to which the stirring blade 20 is attached, the blower 21 that feeds air into the processing tank 1, and the air discharge that discharges the air in the processing tank 1 to the deodorizing device 27. The blower 26 for heating and the heating means 3 for heating the treatment tank 1 are each driven by a command from the control device 7. In this case, the heating means 3 maintains the inside of the treatment tank 1 at a temperature suitable for the growth of the bacteria because of the generation of the fungus bed. The temperature of the floor once decreases. As a result, when the operation switch is turned on, the heating means 3 is turned on to raise the temperature of the processing tank 1 to the set temperature.
[0052]
Then, the rotary drive shaft 15 is driven by the activation of the electric motor 18, the base end is fixed to the drive shaft 15, and the stirring rod 19 having the stirring blade 20 attached to the distal end portion is rotated, as shown in FIGS. The fermentation base X composed of the fungus bed and the straw put into the treatment tank 1 is stirred and mixed. The rotation speed of the stirring rod 19 is set to 1 to 2 rotations / minute in this example, and the fermentation base X is stirred by the stirring blade 20 to efficiently mix the fungus bed and the koji. In this case, since the stirring blade 20 is attached at a position slightly retracted from the tip of the stirring rod 19, the fermentation base X is not pressed against the wall surface of the processing tank 1. be able to.
[0053]
In the stirring treatment step, the fermentation substrate X is stirred and mixed while reciprocating in the left-right direction of the treatment tank 1 (longitudinal direction of the treatment tank 1 shown in FIG. 3). That is, the stirring bar 19 has a center line Y in the length direction of the rotary drive shaft 15 shown in FIG. 5 in the circumferential direction at equal intervals in the length direction as shown in FIG. The three bases arranged symmetrically in the left-right direction are shifted from each other by 120 ° as the starting point, and the fermenting base is sequentially from the outer stirring bar 19 during forward rotation of the rotary drive shaft 15 and from the inner stirring bar 19 during reverse rotation. The material X is attached so as to be stirred by the stirring blade 20. Further, as shown in FIG. 4, the stirring blade 20 is attached to a position slightly closer to the base end from the tip of the stirring bar 19 (a position about 1/5 lower than the length of the stirring bar 19). As shown in FIG. 5, the mounting angle is inclined at a predetermined angle (in the range of about 30 to 60 °) with respect to the axis of the rotary drive shaft 15 and is orthogonal to the axis of the rotary drive shaft 15. With the center line Y in the length direction as a base point, the agitating blades 20 are symmetrical in the opposite direction to each other in the length direction of the rotary drive shaft 15 (when the rotary drive shaft 15 is rotated forward, fermentation is performed). The base material X is attached to the stirring bar 19 at an inclination so that the fermentation base material X moves to the center position of the processing tank 1 and the fermentation base material X moves to the end side of the processing tank 1 during reverse rotation.
[0054]
That is, the stirring blades 20 are all arranged at the same line as shown in FIG. 5 because the respective stirring rods 19 are attached to the rotary drive shaft 15 by shifting by 60 ° along the circumferential direction. It cannot be confirmed by the status. However, in order to explain the mounting state of each stirring blade 20, it is assumed that the stirring rod 19 to which each stirring blade 20 is mounted protrudes in the same direction as shown in FIG. 5 on the axis of the rotary drive shaft 15. In this state, each stirring blade 20 shown in FIG. 5 is inclined at symmetrical positions at the same angle with respect to the axis of the rotary drive shaft 15 on both sides of the center line Y perpendicular to the axis of the rotary drive shaft 15. Installed.
[0055]
For example, when the rotary drive shaft 15 is rotated in the forward rotation direction (rightward direction) in FIG. 5 by the activation of the electric motor 18, each stirring blade 20 fixed to the stirring rod 19 is connected to the center line Y of the rotary drive shaft 15. Therefore, the fermentation substrate X in the treatment tank 1 is stirred and mixed while moving in the center direction in the longitudinal direction of the treatment tank 1. This is because the stirring blade 20 is inclined toward the center line Y side of the rotary drive shaft 15 as described above, so that the fermentation substrate X is fermented diagonally by the forward rotation of the rotary drive shaft 15. This is to enter the base X.
[0056]
Further, when the rotary drive shaft 15 is rotated in the reverse direction (left direction) in FIG. 4, the stirring blade 20 is inclined in a direction away from the center line Y of the rotary drive shaft 15. Contrary to the above, the material X is stirred and mixed while moving to the side wall side in the longitudinal direction of the treatment tank 1.
[0057]
Thus, when the stirring rod 19 is rotated forward and backward by the rotary drive shaft 15, the fermentation substrate X reciprocates along the longitudinal direction of the treatment tank 1 while being stirred and mixed by the stirring blade 20. It becomes possible to rapidly and well stir and mix the fermentation base X composed of koji. In this example, the agitation / mixing operation of the fermentation substrate X is performed for about 10 minutes every 2 hours (forward / reverse rotation of the electric motor 18 every 5 minutes), and the agitation / mixing operation of the fermentation substrate X is started. At the same time, the blower 21 of the air supply means 4 and the blower 26 of the air discharge means 5 are simultaneously activated. The air feeding means 4 and the air discharging means 5 continue to operate even when the stirring / mixing operation of the fermentation substrate X is completed.
[0058]
When the air feeding means 4 is activated, the air pressurized to a predetermined pressure by the blower 21 passes through the feeding pipes 22 and 23 (the flow rate adjusting valve 23a is fully opened) from the both side walls of the lower part of the processing tank 1 and the fermentation substrate X Be fed in. The air fed into the treatment tank 1 is heated on the both sides of the treatment tank 1 in a state of being heated compared to the outside air by the pressurization by the blower 21 and the atmospheric temperature heated by the heating means 3 in the mounting frame 8. It passes through the through-hole 24a drilled in the side wall and is fed into the processing tank 1.
[0059]
The air fed into the treatment tank 1 penetrates to the depth of the fermentation substrate X and diffuses and supplies oxygen to the fermentation substrate X. On the fungal bed that constitutes one of the fermentation bases X, microorganisms that are appropriately blended with thermophilic bacteria, mesophilic bacteria, thermophilic bacteria, and anaerobic bacteria are reproduced, activated by the supply of oxygen, Decomposition treatment and moisture and other components (carbon dioxide CO₂Etc.).
[0060]
In the initial stage of treatment of the koji, the temperature of the fermentation substrate X is low and the temperature of the mesophilic bacterium is active and breeding. Therefore, at this stage, some of the thermophilic bacterium is in a dormant state, and in anaerobic bacteria However, since the fermentation base X is very air-permeable at the initial stage, a part of the fermentation base X is dormant in the same manner as thermophilic bacteria. And as the fermentation and decomposition treatment of koji proceeds with the activation of the microorganism group by supplying oxygen, heat is generated, and the temperature of the fermentation substrate X is gradually increased to a temperature (around 70 ° C.) at which high-temperature bacteria propagate. Raise.
[0061]
When the temperature of the fermentation base X rises and reaches the activity / breeding region of the thermophilic bacteria, the thermophilic bacteria that have been dormant so far grow well and efficiently promote the high-temperature fermentation / decomposition treatment of the koji. In this way, as the activation and propagation of the microorganism group is promoted, the high temperature bacteria in the fermentation substrate X perform the decomposition process of the koji, and the temperature also in the medium temperature and low temperature areas, respectively. Microorganisms suitable for the region are active and contribute to fermentation and decomposition treatment of koji. In this case, a group of microorganisms that exist in a temperature region that is not suitable for breeding in each temperature region, for example, some of the thermophilic bacteria that die in the high temperature region, are mostly dormant.
[0062]
As described above, the koji contained in the fermentation substrate X is decomposed well into moisture and other components by the microorganism group activated and propagated in each temperature region, and the moisture is emitted from the fermentation substrate X. Carbon dioxide, ammonia, sulfur compounds generated during fermentation of koji from the exhaust port 25 in the upper part of the processing tank 1 to the deodorizing device 27 through the discharge pipes 28 and 29 by the blower 26 of the air discharge means 5 And so on (hereinafter referred to as malodorous gas).
[0063]
The malodorous gas discharged from the treatment tank 1 through the discharge pipes 28 and 29 to the deodorizing device 27 is once collected and retained in the diffusion cylinder 42. This is because the dust cylinder 42 itself is formed into a bottomed cylindrical shape by appropriately welding small spheres 42a to generate irregularly different fine gaps a. The malodorous gas that has flowed into the gas cylinder cannot flow out as it is, but once it has accumulated in the diffusion cylinder 42, it gradually flows out through the fine gap a into the water in the aeration tank 41. .
[0064]
As a result, the malodorous gas is collected in a state of being pressurized to some extent in the diffuser cylinder 42, and flows out (discharges) so as to ooze out from the minute gap a formed irregularly in the diffuser cylinder 42. In the tank part 41, contact with water is performed satisfactorily, and most of malodorous components (such as ammonia gas) are dissolved and removed. In this way, the primary treatment (deodorizing action) of malodorous gas is performed in the aeration tank unit 41. At this time, the moisture containing the malodor discharged into the dust cylinder 42 together with the malodorous gas flows out from the fine gap a so as to ooze out to the aeration tank section 41 in the same manner as the malodorous gas.
[0065]
The deodorizing process is referred to as a primary process in the present invention. In this case, the primary treatment employs a method in which malodorous components in the malodorous gas are dissolved and removed with inexpensive water, so that the treatment work can be performed inexpensively and easily. Can be greatly reduced.
[0066]
  The malodorous gas that has been subjected to the deodorizing primary treatment is dissolved and removed in water, and is exhausted from the water in the aeration tank 41 to the air layer 49 above it. The air containing the odor exhausted to the air layer 49 (hereinafter referred to as odor) enters the air layer 49 and is accommodated and laid in a housing 58 horizontally installed in the air layer 49. Consist ofOdor transfer speed control device59 is exhausted to the deodorizing agent storage tank 51. At this time,Odor transfer speed control device59 is disposed in the housing 58 so as to partition the aeration tank unit 41 and the deodorant storage tank unit 51.
[0067]
  That is, the primary-processed odor exhausted from the aeration tank unit 41 laid horizontally on the air layer 49.Odor transfer speed control deviceCannot go straight because of 59,Odor transfer speed control deviceAs a result of sewing the space between the hollow sphere 59a and the hollow sphere 59a constituting 59 into the zigzag shape, the odor passes through the air layer 49 in a state in which the moving speed is suppressed and the odor is dispersed radially. Therefore, the movement to the deodorant storage tank part 51 can be suppressed satisfactorily.
[0068]
The odor that has passed through the air layer 49 rises in a radially dispersed state, and flows into the deodorant storage tank 51 that secondarily processes the odor and deodorizes it. The deodorizing agent storage tank unit 51 is configured such that casings 52 to 54 that store a deodorizing agent 56 made of activated carbon or the like are stacked in three stages and can be taken in and out of the tank unit 51 like a drawer in this example. .
[0069]
And the odor which flowed into the said deodorizing agent storage tank part 51 is deodorized by passing sequentially between the deodorizing agents 56 in the housing | casing 52-54 laminated | stacked in multiple steps, and is exhausted from the exhaust hood 60 to the exterior. Discharged. That is, the odor that has been subjected to the primary treatment introduced into the deodorant storage tank unit 51 can pass through the deodorant storage tank unit 51 stacked in a plurality of stages, taking a long contact time with the deodorant 56. Therefore, the secondary process (deodorizing process) by the deodorizing agent 56 can be performed satisfactorily.
[0070]
  This is made possible by performing the first and second processing of the malodorous gas over time. In the present invention, the malodorous gas is discharged into the water in the aeration tank section 41 by using the dust cylinder 42. By suppressing the odor, most of the odorous components in the odorous gas can be easily dissolved and removed in water (primary treatment of the odorous components), and after that, most of the odorous components are deodorized from the aeration tank unit 41. The odor exhausted in this manner is laid horizontally on the air layer 49 above the aeration tank 41.Odor transfer speed control deviceWhile passing through 59, it is divided and diffused and introduced into the deodorant storage tank 51. The odor that has flowed into the tank portion 51 is sequentially adsorbed by the deodorizer 56 by passing through the plurality of cases 52 to 54 filled with the deodorizer 56, and the secondary treatment of the odor deodorization is good over time. Can be done.
[0071]
  Also in this secondary treatment, exhaust from the aeration tank unit 41 is provided in the air layer 49.Odor transfer speed control device59 is dispersed and is discharged into the deodorant storage tank 51 with the discharge speed reduced, so that the odor reduced by malodor components by the primary deodorization treatment can be secondarily treated better. The air from which the bad odor is removed is discharged from the exhaust port 62 (see FIG. 6) of the exhaust hood 60 to the outside. As a result, the malodorous gas generated during the fermentation process of koji is not directly discharged to the outside, and the member that deodorizes the malodorous gas uses inexpensive water as the primary treatment. In addition, since the deodorizer 56 only performs secondary treatment of odor, the adsorption burden can be reduced and the use period can be easily extended.
[0072]
The water in the aeration tank unit 41 opens and closes the drainage and water supply valves 45 and 48 by a command signal from the control device 7 every fixed time (for example, 2 hours), and exchanges about 2/3 thereof. Water supply and drainage are constantly monitored by a water level gauge 46, and a fixed amount of water is always stored in the tank 41.
[0073]
When the deodorizer 56 is replaced, the casings 52 to 54 are pulled out from the deodorizer storage tank 51 using the handle 57 like a drawer, and after the new deodorizer 56 is packed, the deodorizer storage tank 51 is again filled. By accommodating the casings 52 to 54 in the interior, the deodorizing agent 56 can be easily exchanged.
[0074]
As described above, when the fermentation process of the koji contained in the fermentation substrate X proceeds and a certain time (for example, 2 hours from the previous stirring time of the fermentation substrate X) has elapsed, the motor 18 is instructed by a command from the control device 7. Is started, the stirring rod 19 is rotated, and the fermentation substrate X is stirred and mixed. In this case, the start-up time of the electric motor 18 is 5 minutes each in the forward and reverse rotations in this example. The switching direction and starting time of the rotation direction are set in advance by the control device 7.
[0075]
When the stirring blade 20 starts stirring and mixing the fermentation substrate X by the rotation of the stirring rod 19, the fermentation substrate X reciprocates along the longitudinal direction of the treatment tank 1 by the forward and reverse action of the electric motor 18. As described above, the stirring blades 20 fixed to the stirring rod 19 are fixed to the stirring rod 19 at a predetermined angle with respect to the axis of the rotary drive shaft 15, respectively. During the stirring and mixing of the material X, the fermentation substrate X can be easily reciprocated in the treatment tank 1.
[0076]
When the fermentation base X starts to move in the processing tank 1, the temperature of the fermentation base X is temporarily lowered by the air that is constantly fed from the blower 21 into the processing tank 1. This is because the center part of the fermentation substrate X is higher in temperature than other parts due to the fermentation and decomposition of microorganisms, especially the activation and propagation of thermophilic bacteria and mesophilic bacteria (the state before stirring and mixing). Although it was in a state, when the temperature change in the fermentation base material X was observed, the temperature of the fermentation base material X dropped once every 2 hours, and the stirring / mixing of the fermentation base material X was stopped (the electric motor 18 was stopped). Until the next time the electric motor 18 is started (about 2 hours), the temperature of the fermentation base X gradually increases.
[0077]
As described above, the stirring rod 19 is rotated, and the fermentation substrate X can be moved by the stirring blade 20 while stirring and mixing the high temperature region and the low temperature region. The air fed into the treatment tank 1 from the blower 21 can be in uniform contact with the fermentation base X moving in the treatment tank 1, thereby reducing the temperature of the fermentation base X. is there. In this case, the blower 26 of the air discharge means 5 is always activated, the air from the blower 21 is permeated into the fermentation base X, permeates the fermentation base X, and is ejected to the upper part in the processing tank 1. The hot air of the fermentation substrate X is sucked well, discharged to the deodorizing device 27, and deodorized.
[0078]
Thus, while the fermentation base X can suppress a temperature rise favorably by the air feeding means 4 and the air discharge means 5, and by moving the fermentation base X by the stirring / mixing action of the stirring blade 20, As a result, the fermentation substrate X itself can evaporate well. As a result, the fermentation substrate X is not hardened by moisture and is in a state containing a little moisture, so that the air from the blower 21 is easily fermented. It penetrates into the inside of the substrate X, and the temperature of each part of the fermentation substrate X is almost equalized. This is because all of the fermentation base X can be moved by the stirring blade 20, and thereby the aerobic fermentation of the fermentation base X can be performed satisfactorily.
[0079]
As shown in FIG. 5, the fermentation decomposition treatment of koji is coupled with the fact that the fermentation substrate X reciprocates in the treatment tank 1 during the stirring and mixing, and is constantly supplied with air from the blower 21. At the time of rotation of the stirring blade 20, the air is evenly contacted with the fermentation base X, so that the fermentation temperature temporarily decreases, but the fermentation base X has good air permeation and has been dormant until now. The low / mesophilic bacterium which has been released is rapidly bred and activated, and the cocoon in the fermentation base X is efficiently fermented and decomposed into water and other components.
[0080]
And after rotating the stirring blade 20 forward / reversely every 5 minutes, when the electric motor 18 is stopped, the stirring / mixing work of the fermentation base X is completed, and the fermentation base X is fermented in a stationary state from that point. The fermentation temperature rises every time a predetermined fermentation time elapses, and the koji is fermented at a high temperature for efficient decomposition. Moreover, the temperature in the processing tank 1 is always measured by the temperature controller 3a, and when the temperature reaches a predetermined temperature (for example, about 40 ° C.), the energization to the heating means 3 is stopped. In addition, at the time of high-temperature fermentation of the fermentation base material X (for example, when the temperature of the fermentation base material X is measured with a thermocouple 35 and the measured temperature exceeds 40 ° C., for example), in this example, the heating means 3 is energized. Is stopped by a command from the control device 7.
[0081]
When the fermentation substrate X is subjected to a high temperature fermentation treatment, the koji contained in the fermentation substrate X is efficiently decomposed by the microorganism group of the high temperature bacteria to be decomposed into water and other components, and the water is fermented. It evaporates by heat and is forcibly discharged to the deodorizing device 27 by the air discharging means 5 together with carbon dioxide, ammonia, etc. generated during the fermentation process, and deodorized.
[0082]
When the moisture content of the fermentation substrate X is reduced below a set value, the watering means 6 is driven by a command from the control device 7 and a certain amount of water is fermented from the watering nozzle 30 disposed in the treatment tank 1. Supply water to material X. The water supply time and water supply amount can be determined by detecting the water content by a moisture content sensor (not shown) and starting water supply, or by knowing the processing time of dredging in advance by a test or the like and supplying water at regular intervals. Well, in terms of water supply, the water supply for each moisture content should be determined by a prior test to supply the optimum amount of water, or the water supply corresponding to the pre-tested soot throughput should be known. By performing watering at regular intervals during the fermentation treatment of the fermentation substrate X, the fermentation substrate X is maintained at a predetermined moisture content.
[0083]
By the above, when discharging the fermentation base X which finished the fermentation process, the discharge lid 12 which covers the discharge port 11 of the processing tank 1 is opened, and the discharge port 11 is opened. Thereafter, an operation switch (not shown) of the organic waste treatment apparatus A is turned on to start the electric motor 18. In this case, the electric motor 18 is rotated only in the normal rotation direction. When the electric motor 18 rotates in the forward rotation direction, the stirring rod 19 of the stirring means 2 rotates in the right direction shown in FIG. The stirring blade 20 fixed to the stirring rod 19 by the right rotation of the stirring rod 19 is attached so as to incline in a direction opposite to each other at a predetermined angle with respect to the axis of the rotary drive shaft 15. The fermentation substrate X in the tank 1 is moved to the center position in the length direction of the processing tank 1 and can be automatically discharged from the discharge port 11 to the outside of the processing tank 1 without soiling the hands. Therefore, if the bag which stores the fermentation base material X is set below the discharge port 11, the fermentation base material X can be easily stored. If the fermentation base material X stored in the bag is left as it is for about one month, it can be fermented well and used as a fertilizer.
[0084]
In addition, although the deodorizing apparatus 27 of this invention demonstrated the system which discharges the water of the aeration tank part 41 from the drain pipe 47, the said drain pipe 47 is connected to the water supply pipe 31 of the processing tank 1, and from the aeration tank part 41, it is. Even if the water to be drained is sprinkled into the treatment tank 1 through the sprinkling nozzle 30 and used to prevent the inside of the treatment tank 1 from becoming dry, the present invention is established.
[0085]
【The invention's effect】
Since the present invention is configured as described above, it has the following effects.
(1) In the present invention, the malodorous gas such as ammonia, which is produced by the decomposition of most of the straw into ammonia, methane gas, carbon dioxide and water by the fermentation of microorganisms, is brought into contact with the water in the aeration tank section. The primary treatment for dissolving and removing most of the malodorous portion, and the primary-treated odor is further sent to the deodorant-containing tank section and subjected to secondary treatment with the deodorizer, so that the post-primary treatment Since it comprised so that an odor could be deodorized, the deodorizing process of the malodorous gas which generate | occur | produces by the fermentation process of koji can be performed rapidly and reliably with a simple structure.
[0086]
Further, in the primary treatment of malodorous gas, the present invention provides a bottomed cylindrical spray cylinder formed by forming a required number of fine gaps by, for example, heat-bonding a large number of small spheres made of resin. Since it is configured to discharge the malodorous gas into the water in the aeration tank while being pressurized, the malodorous gas is slowly discharged in small amounts into the water in the aeration tank. Since it can be satisfactorily performed and is discharged into water in small amounts, dissolution / removal with water is facilitated, and malodorous components can be efficiently deodorized.
[0087]
  Furthermore, the present invention provides an odor with less malodorous components that is diluted by passing through the water in the aeration tank.Can not go straight due to the presence of the odor moving speed suppressing device horizontally mounted on the air layer, and sew the spaces between the hollow spheres and the hollow spheres constituting the odor moving speed suppressing device in a zigzag shape. As a result of entering the air layer in a state of being dispersed radially by entering, the movement to the deodorant containing tank part can be favorably suppressed, thereby The odor isBy deodorantGood over timeSince the deodorizing process is completed by adsorbing and performing the secondary process, the deodorizing agent can be less polluted, and the primary process of the malodorous gas is performed with inexpensive water.What you can doIn combination with this, the running cost of the deodorizing treatment can be significantly reduced. In addition, when replacing the deodorant, the housing containing the deodorant was configured so that it could be pulled out and taken out from the deodorant storage tank, so that the deodorizer was continuously operated for replacement work. This is convenient because it can be done quickly and easily.
