Description

本発明は、水蒸気、粉塵及び悪臭成分を含む気体を処理する脱臭装置に関する。   The present invention relates to a deodorizing apparatus for treating a gas containing water vapor, dust and malodorous components.

従来の汚泥処理では、汚泥を脱水してから焼却し、焼却物を埋設することが一般的であった。このような汚泥処理は相当の処理費用がかかるとともに、焼却物の埋設地を確保する必要がある。そこで、汚泥から肥料を製造し、汚泥の有効利用を図る技術が提唱されている（特許文献１を参照）。図２に示すように、この技術に係る肥料製造装置１０は、脱水機１２、造粒装置１４、貯留装置１６を有する。汚泥を脱水機１２によって脱水して脱水ケーキとし、脱水ケーキに生石灰を添加して造粒装置１４に通し、造粒装置１４によって脱水ケーキを粒状の肥料とし、製造した肥料を貯留装置１６に蓄え、適宜袋詰め等して製品として出荷する。肥料製造装置１０によって製造される肥料は保存可能であり、肥料の粒径を所定の大きさとすることができる。   In the conventional sludge treatment, the sludge is generally dehydrated and then incinerated to bury the incinerated product. Such sludge treatment requires considerable treatment costs, and it is necessary to secure a land for incineration. Then, the technique which manufactures fertilizer from sludge and aims at the effective utilization of sludge is proposed (refer patent document 1). As shown in FIG. 2, the fertilizer manufacturing apparatus 10 according to this technique includes a dehydrator 12, a granulator 14, and a storage device 16. Sludge is dehydrated by a dehydrator 12 to obtain a dehydrated cake, quick lime is added to the dehydrated cake and passed through the granulator 14, the dehydrated cake is converted to granular fertilizer by the granulator 14, and the produced fertilizer is stored in the storage device 16. The product is shipped as a product by appropriately bagging. The fertilizer manufactured by the fertilizer manufacturing apparatus 10 can be stored, and the particle size of the fertilizer can be set to a predetermined size.

脱水ケーキの乾燥を促進するために、空気を造粒装置１４に供給し、造粒装置１４内の空気を排気している。造粒装置１４の排気中には、脱水ケーキから発生する水蒸気と、脱水ケーキ、生石灰及び肥料から発生する粉塵と、汚泥に由来する悪臭成分とが含まれている。このため、造粒装置１４の排気を大気放散するには、排気を脱臭処理し、排気中から粉塵と悪臭成分を除去しなければならない。   In order to accelerate the drying of the dehydrated cake, air is supplied to the granulator 14 and the air in the granulator 14 is exhausted. The exhaust gas from the granulator 14 contains water vapor generated from the dehydrated cake, dust generated from the dehydrated cake, quicklime and fertilizer, and malodorous components derived from sludge. For this reason, in order to dissipate the exhaust gas from the granulator 14 to the atmosphere, the exhaust gas must be deodorized to remove dust and malodorous components from the exhaust gas.

造粒装置１４の排気を脱臭処理する技術として、図２に示す脱臭装置が提唱されている（特許文献２を参照）。この脱臭装置８０は、冷却器８２、脱臭容器８４を有し、上流側から冷却器８２と脱臭容器８４が直列に配置されている。冷却器８２は造粒装置１４の排気が通る配管と、配管外部に設けられた放熱用フィン８６を有し、配管中の排気を空冷可能に構成されている。脱臭容器８４は、その内部に繊維質又は多孔質の薬品含浸媒体８８が封入されており、薬品含浸媒体８８には造粒装置１４の排気中の悪臭成分と反応する薬品が含浸されている。   As a technique for deodorizing the exhaust gas from the granulating apparatus 14, a deodorizing apparatus shown in FIG. 2 has been proposed (see Patent Document 2). The deodorizing device 80 includes a cooler 82 and a deodorizing container 84, and the cooler 82 and the deodorizing container 84 are arranged in series from the upstream side. The cooler 82 includes a pipe through which the exhaust gas from the granulating apparatus 14 passes and a heat radiation fin 86 provided outside the pipe, and is configured so that the exhaust in the pipe can be air-cooled. The deodorizing container 84 is filled with a fibrous or porous chemical impregnation medium 88, and the chemical impregnation medium 88 is impregnated with a chemical that reacts with malodorous components in the exhaust gas from the granulator 14.

吸引機４８が脱臭装置８０の下流に設置されており、造粒装置１４の排気を脱臭装置８０を介して吸引可能に構成されている。
肥料製造装置１０を稼動させるときは、吸引機４８によって排気を造粒装置１４から脱臭装置８０に吸引する。脱臭装置８０に吸引された排気は、まず、冷却器８２に流入する。冷却器８２において放熱用フィン８６が排気の熱を奪い、排気が冷却され、排気中の水蒸気が凝縮して水滴となり、水滴が排気中の粉塵を捕捉し、粉塵が排気中から除去される。粉塵を捕捉した水は冷却器８２の底部に集められ排水口８２ａから排出される。 A suction machine 48 is installed downstream of the deodorizing device 80, and the exhaust of the granulating device 14 can be sucked through the deodorizing device 80.
When operating the fertilizer manufacturing apparatus 10, exhaust air is sucked from the granulating apparatus 14 to the deodorizing apparatus 80 by the suction machine 48. The exhaust sucked into the deodorizing device 80 first flows into the cooler 82. In the cooler 82, the heat dissipating fins 86 take the heat of the exhaust, the exhaust is cooled, the water vapor in the exhaust is condensed into water droplets, the water droplets capture the dust in the exhaust, and the dust is removed from the exhaust. The water that has captured the dust is collected at the bottom of the cooler 82 and discharged from the drain 82a.

次いで、粉塵が除去された排気が冷却器８２から脱臭容器８４に流入し、脱臭容器８４内の薬品含浸媒体８８中を通る。排気中の悪臭成分が薬品含浸媒体８８に含浸されている薬品と接触して反応し、悪臭成分が排気中から除去される。脱臭容器８４を出た排気は、粉塵及び悪臭成分を除去されて大気放散可能な状態となっている。薬品含侵媒体８８から漏出した薬液は脱臭容器８４の底部に集められ排水口８４ａから排出される。
特許第２９８０８７７号公報 特許第３１００９３８号公報 Next, the exhaust gas from which the dust has been removed flows from the cooler 82 into the deodorization container 84 and passes through the chemical impregnation medium 88 in the deodorization container 84. The malodorous component in the exhaust gas reacts with the chemical impregnated in the chemical impregnation medium 88, and the malodorous component is removed from the exhaust gas. The exhaust gas exiting the deodorizing container 84 is in a state in which dust and malodorous components are removed and can be diffused into the atmosphere. The chemical solution leaked from the chemical impregnation medium 88 is collected at the bottom of the deodorizing container 84 and discharged from the drain outlet 84a.
Japanese Patent No. 2980877 Japanese Patent No. 3100138

しかしながら、前述の脱臭装置８０の冷却器８２では、排気の冷却を空冷によって行うので、冷却効率が高いとは言えず、排気中の水蒸気から凝縮する水滴の量が少ない。凝縮する水滴の量が少ないので、水滴に付着して排気中から除去される粉塵の量も少なくなり、脱臭容器８４に流入する排気中に粉塵が残留してしまう。このため、排気とともに粉塵が薬品含浸媒体８８を通ることとなり、薬品含浸媒体８８が粉塵によって目詰りし、薬品含浸媒体８８の寿命が短くなる。
本発明は、上記問題を解決するものであり、その目的とするところは、粉塵と悪臭成分を含む気体から粉塵を効率よく捕捉でき、悪臭成分と反応する薬品を含浸させた媒体の寿命が長くなり、高い脱臭能力を有する脱臭装置を提供することである。 However, in the cooler 82 of the deodorizing apparatus 80 described above, since the exhaust is cooled by air cooling, it cannot be said that the cooling efficiency is high, and the amount of water droplets condensed from the water vapor in the exhaust is small. Since the amount of water droplets to be condensed is small, the amount of dust that adheres to the water droplets and is removed from the exhaust gas is reduced, and dust remains in the exhaust gas flowing into the deodorizing container 84. For this reason, dust passes through the chemical-impregnated medium 88 together with the exhaust gas, and the chemical-impregnated medium 88 is clogged by the dust, and the life of the chemical-impregnated medium 88 is shortened.
The present invention solves the above-mentioned problems, and the object of the present invention is to efficiently capture dust from a gas containing dust and malodorous components and to extend the life of a medium impregnated with a chemical that reacts with malodorous components. It is to provide a deodorizing apparatus having a high deodorizing ability.

本発明は、その課題を解決するために以下のような構成をとる。請求項１の発明に係る脱臭装置は、水蒸気、粉塵及び悪臭成分を含む気体を処理する脱臭装置であって、気体が衝突するバッフルと、バッフルと衝突した気体に対して水を噴霧する噴霧ノズルと、水を噴霧された気体中の粉塵を捕捉する樹脂フィルタと、粉塵を除去した気体中の悪臭成分と反応する薬品が含浸されている薬品含浸媒体と、排水口と、を有する脱臭槽によって構成されている。   The present invention adopts the following configuration in order to solve the problem. The deodorizing apparatus according to the first aspect of the present invention is a deodorizing apparatus for processing a gas containing water vapor, dust and malodorous components, and a baffle with which the gas collides, and a spray nozzle for spraying water on the gas colliding with the baffle. A deodorizing tank having a resin filter that captures dust in a gas sprayed with water, a chemical impregnation medium impregnated with a chemical that reacts with malodorous components in the gas from which dust has been removed, and a drain outlet It is configured.

請求項１の発明によれば、水蒸気、粉塵及び悪臭成分を含む気体を脱臭装置の脱臭槽に通すと、気体がバッフルに衝突する。気体中の粉塵のうち粒径が大きいものは、バッフルに衝突してその勢いが減じられてその一部分が気体中から除去される。
バッフルと衝突した気体に水を噴霧すると、気体の温度が低下し、気体中の水蒸気が凝縮して水滴となる。バッフルで捕捉しきれずに気体中に残った粉塵が、噴霧した水と凝縮した水滴によって捕捉され、さらに気体中から除去される。
水を噴霧した気体を樹脂フィルタに通すと、気体中の粉塵が樹脂フィルタによって捕捉される。気体中の粉塵の量は減少しているので、樹脂フィルタにかかる負荷は小さい。また、気体に噴霧した水によって樹脂フィルタを洗浄でき、樹脂フィルタが捕捉した粉塵を洗い流すことができるので、樹脂フィルタの寿命が長くなる。 According to the invention of claim 1, when a gas containing water vapor, dust and malodorous components is passed through the deodorizing tank of the deodorizing device, the gas collides with the baffle. Among the dust in the gas, the one having a large particle size collides with the baffle, the momentum is reduced, and a part thereof is removed from the gas.
When water is sprayed onto the gas that has collided with the baffle, the temperature of the gas decreases, and water vapor in the gas condenses into water droplets. Dust remaining in the gas without being completely captured by the baffle is captured by the sprayed water and condensed water droplets, and further removed from the gas.
When the gas sprayed with water is passed through the resin filter, dust in the gas is captured by the resin filter. Since the amount of dust in the gas is decreasing, the load on the resin filter is small. Moreover, since the resin filter can be washed with water sprayed on the gas and the dust captured by the resin filter can be washed away, the life of the resin filter is prolonged.

気体中の粉塵を除去したら、気体を薬品含浸媒体に通す。気体中の悪臭成分が薬品含浸媒体の薬品に接触して反応し、気体中から悪臭成分が除去される。気体中の粉塵は既に除去されているので薬品含浸媒体が粉塵によって目詰りすることはなく、薬品含浸媒体の寿命が長くなる。
脱臭槽を出た気体は粉塵と悪臭成分を除去されて大気放散可能な状態となる。
脱臭槽内には、気体から除去された粉塵、凝縮した水、噴霧された水、薬品含侵媒体から漏出した薬液が廃水として溜まるが、適宜、溜まった廃水を排水口から脱臭槽外に排出する。 After removing the dust in the gas, the gas is passed through the chemical impregnation medium. The malodorous component in the gas contacts and reacts with the chemical in the chemical impregnation medium, and the malodorous component is removed from the gas. Since the dust in the gas has already been removed, the chemical impregnation medium is not clogged by the dust, and the life of the chemical impregnation medium is extended.
The gas exiting the deodorizing tank is in a state in which dust and malodorous components are removed and can be released into the atmosphere.
In the deodorization tank, dust removed from the gas, condensed water, sprayed water, and chemicals leaking from the chemical-impregnated medium are collected as waste water, but the collected waste water is appropriately discharged from the drain outlet to the outside of the deodorization tank. To do.

請求項２の発明に係る脱臭装置は、請求項１記載の脱臭槽が複数直列に配置されている。
気体を脱臭槽に一回通しただけでは、粉塵及び悪臭成分を所定量まで除去できない場合であっても、複数の脱臭槽を直列に配置して気体を脱臭槽に複数回通すことによって、気体から粉塵及び悪臭成分を所定量まで除去できる。 In the deodorizing apparatus according to the invention of claim 2, a plurality of deodorizing tanks of claim 1 are arranged in series.
Even if the dust and malodorous components cannot be removed up to a predetermined amount by passing the gas through the deodorization tank once, the gas can be removed by arranging a plurality of deodorization tanks in series and passing the gas through the deodorization tank multiple times. Dust and malodorous components can be removed to a predetermined amount.

本発明に係る脱臭装置は、粉塵と悪臭成分を含む気体から粉塵を効率よく捕捉でき、悪臭成分と反応する薬品を含浸させた媒体の寿命が長くなり、高い脱臭能力を発揮できる。   The deodorizing apparatus according to the present invention can efficiently capture dust from a gas containing dust and malodorous components, extend the life of a medium impregnated with a chemical that reacts with the malodorous components, and can exhibit high deodorizing ability.

The granulator 14 has an air supply line 18 and an exhaust line 20, and the exhaust line 20 is connected from the granulator 14 to the deodorizing device 22.

脱臭装置２２は脱臭槽２４を有する。脱臭槽２４は底が漏斗状をなす容器である。脱臭槽２４内は垂直な仕切板２６が設置されており、仕切板２６が脱臭槽２４内を除塵室２８と脱臭室３０に分けている。仕切板２６は脱臭槽２４の底まで達してはおらず、除塵室２８の底部分と脱臭室３０の底部分とが互いに接続されている。除塵室２８の上部分には前室３２が形成されている。前室３２の一方の端部分が入口４２となって排気ライン２０が繋ぎこまれており、前室３２の他方の端部分が除塵室２８につながっている。前室３２内には複数枚のバッフル３４が設置されており、入口４２から流入する排気がバッフル３４に衝突しつつ前室３２内を流れて除塵室２８に流出する構成となっている。   The deodorizing device 22 has a deodorizing tank 24. The deodorization tank 24 is a container whose bottom forms a funnel shape. A vertical partition plate 26 is installed in the deodorization tank 24, and the partition plate 26 divides the deodorization tank 24 into a dust removal chamber 28 and a deodorization chamber 30. The partition plate 26 does not reach the bottom of the deodorizing tank 24, and the bottom portion of the dust removing chamber 28 and the bottom portion of the deodorizing chamber 30 are connected to each other. A front chamber 32 is formed in the upper portion of the dust removal chamber 28. One end portion of the front chamber 32 serves as an inlet 42 to connect the exhaust line 20, and the other end portion of the front chamber 32 is connected to the dust removal chamber 28. A plurality of baffles 34 are installed in the front chamber 32, and exhaust gas flowing from the inlet 42 flows through the front chamber 32 and flows out to the dust removal chamber 28 while colliding with the baffle 34.

除塵室２８は噴霧ノズル３６と樹脂フィルタ３８を有する。噴霧ノズル３６は除塵室２８の天井部分に設置されており、除塵室２８の下方に向って水を噴霧可能に構成されている。噴霧ノズル３６よりも下方の除塵室２８の中間部分に樹脂フィルタ３８が設置されている。樹脂フィルタ３８は、排気中の粉塵を捕捉可能な能力を有する。
脱臭室３０は多孔質又は繊維質の薬品含浸媒体４０を有する。薬品含浸媒体４０は脱臭室３０の中間部分に設置されており、造粒装置１４から排出される排気中の悪臭成分と反応する薬品が含浸されている。脱臭室３０の上部分には出口４４が形成されている。
脱臭槽２４の底中央部分には排水口４６が形成されており、除塵室２８の底部分及び脱臭室３０の底部分に溜まる廃水を適宜排出可能に構成されている。
吸引機４８が脱臭室３０の出口４４に接続されており、造粒装置１４から排気を排気ライン２０及び脱臭装置２２を介して吸引し、大気放散可能に構成されている。 The dust removal chamber 28 has a spray nozzle 36 and a resin filter 38. The spray nozzle 36 is installed in the ceiling portion of the dust removal chamber 28 and is configured to spray water toward the lower side of the dust removal chamber 28.

A suction machine 48 is connected to the outlet 44 of the deodorizing chamber 30, and exhaust air is sucked from the granulating device 14 through the exhaust line 20 and the deodorizing device 22 so as to be dissipated into the atmosphere.

次に、作用について説明する。
肥料製造装置１０が汚泥と生石灰から肥料を製造する。給気ライン１８から造粒装置１４に空気が供給され、造粒装置１４内で脱水ケーキの乾燥が促進される。吸引機４８を稼動させて、造粒装置１４内の空気を排気として脱臭装置２２に吸引する。排気中には脱水ケーキから発生する水蒸気と、脱水ケーキ、生石灰及び肥料から発生する粉塵と、汚泥に由来する悪臭成分が含まれている。 Next, the operation will be described.
The fertilizer manufacturing apparatus 10 manufactures fertilizer from sludge and quicklime. Air is supplied from the air supply line 18 to the granulator 14, and drying of the dewatered cake is promoted in the granulator 14. The suction machine 48 is operated, and the air in the granulating device 14 is sucked into the deodorizing device 22 as exhaust. The exhaust gas contains water vapor generated from the dehydrated cake, dust generated from the dehydrated cake, quicklime and fertilizer, and malodorous components derived from sludge.

排気が排気ライン２０を通って入口４２から脱臭槽２４の前室３２に流入してバッフル３４に衝突する。排気中の粉塵のうち粒が大きいものはバッフル３４に衝突して勢いが減じられ、その一部分が排気中から除去される。
バッフル３４と衝突しつつ前室３２を通った排気が除塵室２８に流入する。除塵室２８に流入した排気に噴霧ノズル３６から水が噴霧される。水を噴霧された排気の温度が低下し、排気中の水蒸気が凝縮して水滴となる。バッフル３４によって捕捉されずに排気中に残った粉塵の一部が、噴霧された水と凝縮した水滴によって捕捉される。噴霧された水、凝縮した水滴及びこれらに捕捉された粉塵が脱臭槽２４の底部分に流れ落ちる。 Exhaust gas flows into the front chamber 32 of the deodorizing tank 24 from the inlet 42 through the exhaust line 20 and collides with the baffle 34. Large particles of dust in the exhaust gas collide with the baffle 34 to reduce the momentum, and a part of the dust is removed from the exhaust gas.
Exhaust gas that has passed through the front chamber 32 while colliding with the baffle 34 flows into the dust removal chamber 28. Water is sprayed from the spray nozzle 36 to the exhaust gas flowing into the dust removal chamber 28. The temperature of the exhaust gas sprayed with water decreases, and water vapor in the exhaust gas is condensed to form water droplets. Part of the dust that remains in the exhaust without being captured by the baffle 34 is captured by the sprayed water and condensed water droplets. The sprayed water, the condensed water droplets, and the dust trapped therein flow down to the bottom portion of the deodorizing tank 24.

水を噴霧された気体が樹脂フィルタ３８を通って除塵室２８の底部分に流入する。排気中に残存する粉塵は樹脂フィルタ３８によって捕捉される。排気中の粉塵の量は既に減少しているので樹脂フィルタ３８の負担は小さい。樹脂フィルタ３８に捕捉された粉塵は噴霧ノズル３６から噴霧されて流れ落ちる水によって洗い流される。
排気が除塵室２８の底部分から脱臭室３０の底部分に流入し、薬品含浸媒体４０を通って脱臭室３０の出口４４に流れる。薬品含浸媒体４０の薬品が排気中の悪臭成分と接触して反応し、排気中から悪臭成分が除去される。排気中の粉塵は既に除去されているので、薬品含浸媒体４０が粉塵によって目詰りすることは防止されている。 The gas sprayed with water flows into the bottom portion of the dust removing chamber 28 through the resin filter 38. Dust remaining in the exhaust is captured by the resin filter 38. Since the amount of dust in the exhaust has already decreased, the burden on the resin filter 38 is small. The dust trapped on the resin filter 38 is washed away by the water sprayed from the spray nozzle 36 and flowing down.
The exhaust gas flows from the bottom portion of the dust removing chamber 28 into the bottom portion of the deodorizing chamber 30 and flows through the chemical impregnation medium 40 to the outlet 44 of the deodorizing chamber 30. The chemicals in the chemical impregnation medium 40 come into contact with the malodorous components in the exhaust gas and react to remove the malodorous components from the exhaust gas. Since the dust in the exhaust gas has already been removed, the chemical impregnation medium 40 is prevented from being clogged by the dust.

脱臭室３０の出口４４に流れた排気は、吸引機４８によって吸引されて大気放散される。大気放散される排気からは粉塵、悪臭成分が除去されているので、そのまま大気放散できる。
脱臭槽２４の底には、排気から捕捉された粉塵、凝縮した水、噴霧された水、薬品含浸媒体４０から漏出した薬液が廃水として溜まる。溜まった廃水は排水口４６から適宜排出される。
排気を脱臭装置２２の脱臭槽２４に一回通しただけでは排気中の粉塵や悪臭成分を所定量以下にできない場合、複数の脱臭槽２４を直列に配置し、排気を脱臭槽２４に複数回通す。排気を脱臭槽２４に複数回通すことによって、大気放散する排気中の粉塵、悪臭成分を所定量以下にできる。 The exhaust gas that has flowed to the outlet 44 of the deodorizing chamber 30 is sucked by the suction device 48 and diffused into the atmosphere. Since dust and malodorous components are removed from the exhausted air, the air can be released as it is.
At the bottom of the deodorization tank 24, dust trapped from the exhaust, condensed water, sprayed water, and chemical liquid leaking from the chemical impregnation medium 40 are collected as waste water. The accumulated waste water is discharged from the drain 46 as appropriate.
If the dust and malodorous components in the exhaust gas cannot be reduced below a predetermined amount by passing the exhaust gas once through the deodorizing tank 24 of the deodorizing device 22, a plurality of deodorizing tanks 24 are arranged in series, and the exhaust gas is passed through the deodorizing tank 24 a plurality of times. Pass through. By passing the exhaust gas through the deodorizing tank 24 a plurality of times, the dust and malodorous components in the exhaust gas that are diffused into the atmosphere can be reduced to a predetermined amount or less.
