Description

本発明は、駐車場や住宅敷地等の路面に積もった氷雪を融かす融雪設備に係り、とくに暖房装置や給湯装置等の燃焼装置の排熱を利用する融雪設備に関する。   The present invention relates to a snow melting facility that melts ice and snow accumulated on a road surface such as a parking lot or a residential site, and more particularly to a snow melting facility that uses exhaust heat of a combustion device such as a heating device or a hot water supply device.

降雪地では、従来から路面の雪を融かすための融雪設備（いわゆるロードヒーティングシステム）が用いられている。これらの設備は、路面下の熱源として、電気を利用した発熱体や、温水を利用したもの、あるいは各種の排熱を利用したものがある。   Conventionally, snow melting facilities (so-called road heating systems) for melting snow on the road surface have been used in snowy areas. These facilities include a heat generator using electricity, a device using hot water, or a device using various exhaust heat as a heat source under the road surface.

このうち、排熱を利用した融雪装置としては、例えば、地面下に設けたガスパイプに燃焼排熱を送り込むものが知られている（特開２００１−０４０６０７号）。   Among them, as a snow melting device using exhaust heat, for example, one that sends combustion exhaust heat to a gas pipe provided under the ground is known (Japanese Patent Laid-Open No. 2001-040607).

排熱利用の路面融雪は、電気や高温水を用いた融雪設備に較べ、電気使用料金や灯油料金がかからずランニングコストが抑えられる利点がある。
特開２００１−０４０６０７号 The use of waste heat for melting snow on the road surface has the advantage that the running cost can be reduced because there is no charge for using electricity or kerosene, compared to snow melting equipment using electricity or high-temperature water.
JP 2001-040607 A

ところで、従来の排熱利用の融雪設備は、電気利用や温水利用の融雪設備に較べて融雪効率が悪いという問題がある。   By the way, the conventional snow-melting facility using waste heat has a problem that the snow-melting efficiency is lower than that of snow-melting facility using electricity or hot water.

これは、雪を融かすための熱交換によって、供給する排熱の温度がすぐに低下してしまい、継続的かつ即効性のある融雪が困難になるからである。例えば、前記特許文献１では、排熱の温度低下を防止するため二重管を用いて排熱を路面下に供給する。しかし、二重管を用いると排熱の温度低下を防げても、放出される熱量が絶対的に少ないため、融雪効率は他の手段に較べて格段に劣る。   This is because the temperature of the exhaust heat to be supplied immediately decreases due to the heat exchange for melting the snow, and it is difficult to melt the snow continuously and quickly. For example, in Patent Document 1, exhaust heat is supplied below the road surface using a double pipe in order to prevent temperature reduction of exhaust heat. However, if a double pipe is used, even though the temperature reduction of exhaust heat can be prevented, the amount of heat released is absolutely small, so the snow melting efficiency is much inferior compared to other means.

本発明の目的は、排熱による融雪効率を実際の運用に適する程度に確実に高める点にある。   An object of the present invention is to reliably increase the snow melting efficiency by exhaust heat to an extent suitable for actual operation.

前記目的を達成するため、本発明に係る路面の融雪設備は、路面の下に蓄熱空間を設け、該蓄熱空間の下面に所定の深度をもって金属製の内部中空体を設ける一方、当該蓄熱空間に、燃焼装置の排熱を供給する排熱供給管と、排熱を外気に放出する排熱放出管とを設ける（請求項１）。   In order to achieve the above object, the road surface snow melting facility according to the present invention provides a heat storage space below the road surface, and a metal internal hollow body with a predetermined depth on the lower surface of the heat storage space, while the heat storage space An exhaust heat supply pipe for supplying exhaust heat of the combustion device and an exhaust heat release pipe for releasing exhaust heat to the outside air are provided.

かかる構成によれば、金属製の内部中空体が、夏期に地面下に蓄えられた自然の地熱を蓄熱空間に伝達する。このため、排熱供給管を介して蓄熱空間に排熱を供給すれば、蓄熱空間の内部温度は、外気温が低い場合や積雪がある場合でも大幅な温度低下をみせない。   According to this configuration, the metal internal hollow body transmits natural geothermal heat stored under the ground in the summer to the heat storage space. For this reason, if exhaust heat is supplied to the heat storage space via the exhaust heat supply pipe, the internal temperature of the heat storage space does not show a significant temperature drop even when the outside air temperature is low or there is snow.

その一方で、冬になっても外気温が高い場合や、陽光により路面温度が高まるような条件では、蓄熱空間に送り込んだ排熱によって、蓄熱空間の内部温度が高まる。余分な熱は金属製の内部中空体を介して地熱として蓄えることが出来るため、初冬〜厳冬期〜春先まで、地面下の温度を高く保つ。蓄えられた地熱は、金属製の内部中空体によって蓄熱空間の温度が低いときは均衡を保つように戻されるので、蓄熱空間の温度は極端に低下することはない。このため、厳冬期でも排熱だけの路面融雪が可能となる。   On the other hand, when the outside air temperature is high even in winter or when the road surface temperature is increased by sunlight, the internal temperature of the heat storage space is increased by the exhaust heat sent to the heat storage space. Since excess heat can be stored as geothermal heat through a metal internal hollow body, the temperature below the ground is kept high from early winter to severe winter to early spring. The stored geothermal heat is returned so as to maintain a balance when the temperature of the heat storage space is low due to the metal internal hollow body, so that the temperature of the heat storage space does not extremely decrease. For this reason, it is possible to melt the road surface only with exhaust heat even in the severe winter season.

請求項２は、蓄熱空間に排熱を送り込む排熱供給管を、内管と外管とからなる二重管とするものである。これにより、蓄熱空間に供給する排熱の温度低下を防止し、蓄熱空間内の温度を高く保つためである。排熱供給管が融雪を行うわけではないから、排熱供給管の断熱性を高めても問題は生じない。   According to a second aspect of the present invention, the exhaust heat supply pipe for sending exhaust heat to the heat storage space is a double pipe composed of an inner pipe and an outer pipe. This is to prevent a decrease in the temperature of the exhaust heat supplied to the heat storage space and keep the temperature in the heat storage space high. Since the exhaust heat supply pipe does not melt snow, there is no problem even if the heat insulation of the exhaust heat supply pipe is enhanced.

請求項３は、地熱を利用するための金属製の内部中空体の形状を、下方先端が鋭利な錐形とするものである。内部中空体は、所定の深度をもって配設し、地熱と蓄熱空間との温度差の均衡を保つように機能してくれればよいので、基本的にその形状は限定されないのであるが、工事のしやすさからいえば、杭打ち装置を用いて効率的に打ち込める形状とすることが望ましいからである。なお、内部中空体を金属製とするのは、熱伝導率の良好な点と、土圧による破損が少ない点を考慮したためである。温度保持やコストの点から云えば鉄を利用することが望ましい。   According to a third aspect of the present invention, the shape of the metal internal hollow body for using geothermal heat is a cone shape with a sharp lower tip. Since the inner hollow body only needs to be arranged at a predetermined depth and function so as to maintain a balance between the temperature difference between the geothermal heat storage space and the heat storage space, the shape is basically not limited. It is because it is desirable to make it a shape that can be driven efficiently using a pile driving device. The reason why the internal hollow body is made of metal is because it takes into consideration the good thermal conductivity and the small damage caused by earth pressure. From the standpoint of temperature maintenance and cost, it is desirable to use iron.

本発明に係る路面の融雪設備によれば、蓄熱空間の温度を、地熱と排熱とによって常に好ましい状態に維持でき、効率的な融雪が可能となる。   According to the road surface snow melting facility according to the present invention, the temperature of the heat storage space can always be maintained in a preferable state by geothermal heat and exhaust heat, and efficient snow melting is possible.

図１は、本発明に係る路面の融雪設備を例示するものである。
この融雪設備は、燃焼装置、例えば室内の暖房装置である灯油ストーブ２の排熱（燃焼排気）を利用する。灯油ストーブ２は、ファンを備えるいわゆるＦＦ式の灯油燃焼ストーブを用いることが出来る。３は家屋の外壁、４は室内の床である。 FIG. 1 illustrates a road surface snow melting facility according to the present invention.
This snow melting facility uses exhaust heat (combustion exhaust) of a kerosene stove 2 which is a combustion device, for example, an indoor heating device. As the kerosene stove 2, a so-called FF type kerosene combustion stove including a fan can be used. 3 is an outer wall of a house, and 4 is an indoor floor.

灯油ストーブ２には排熱供給管１０の一端を接続してあり、この排熱供給管１０を介して灯油ストーブ２の排熱を蓄熱空間２０へ送り込むようにしてある。   One end of the exhaust heat supply pipe 10 is connected to the kerosene stove 2, and the exhaust heat of the kerosene stove 2 is sent to the heat storage space 20 through the exhaust heat supply pipe 10.

また蓄熱空間２０に送った排熱は、排熱解放管５０を介して外気に誘導排出するようにしてある。排熱を強制的に外気に誘導できるよう、排熱解放管５０の適宜箇所にはファン装置５２を設けておくことが望ましい。このファン装置５２は小型のものでよいが、風量（モータ駆動量）が段階的に設定できる構成とすることが望ましい。例えば、灯油ストーブ２から排出される排熱量に応じて排気量を段階的に切り替える等である。   The exhaust heat sent to the heat storage space 20 is guided and discharged to the outside air through the exhaust heat release pipe 50. It is desirable to provide a fan device 52 at an appropriate location of the exhaust heat release pipe 50 so that the exhaust heat can be forcibly guided to the outside air. The fan device 52 may be small, but it is desirable that the air volume (motor drive amount) can be set stepwise. For example, the exhaust amount is switched in stages according to the amount of exhaust heat exhausted from the kerosene stove 2.

排熱供給管１０は、例えば、灯油ストーブ２の背面に接続させた横方向の水平パイプ１１と、この水平パイプ１１の適宜箇所から下方に排熱を導く縦管１４と、この縦管１４の下端に接続させた横管１７とによって構成し、横管１７の他端部を蓄熱空間２０の内部に導いて開放してある。   The exhaust heat supply pipe 10 includes, for example, a horizontal horizontal pipe 11 connected to the back surface of the kerosene stove 2, a vertical pipe 14 that guides exhaust heat downward from an appropriate location of the horizontal pipe 11, and the vertical pipe 14 The horizontal pipe 17 is connected to the lower end, and the other end of the horizontal pipe 17 is led into the heat storage space 20 and opened.

水平パイプ１１は、ＦＦ式の灯油ストーブ２に従来から用いられている排気用の通常の管材を用いて良く、その端部には排気排出用の開口１２があって構わない。この開口１２があっても、横管１７に導かれる排熱の温度は影響を受けない。また、万一、排熱解放管５０が子供の悪戯などによって目詰まりしたり、ファン装置５２が故障したりした場合でも、水平パイプ１１の端部（または適宜箇所）に開口１２があることで、排熱の停滞や滞留に伴う事故を防止できる。   The horizontal pipe 11 may use a normal exhaust pipe material conventionally used for the FF type kerosene stove 2, and may have an exhaust exhaust opening 12 at an end thereof. Even if this opening 12 is present, the temperature of the exhaust heat guided to the horizontal tube 17 is not affected. In addition, even if the exhaust heat release pipe 50 is clogged due to a child's mischief or the fan device 52 breaks down, the end 12 (or an appropriate place) of the horizontal pipe 11 has the opening 12. , Can prevent accidents due to stagnation and retention of exhaust heat.

水平パイプ１１は、家屋の外壁３を貫通させる必要があるため外径を自由に設定することは難しいが、縦管１４と横管１７は外径の制限を受けない。このため、縦管１４と横管１７は、排熱の温度低下を最大限に防止するために二重管の構造とすることが望ましい。また、縦管１４と横管１７は、排熱の温度低下を防ぎつつ蓄熱空間２０に高温の排熱を供給するものであるから、この部分を二重管としたうえで、外管の表面を発泡スチロール等の樹脂系の断熱材で被覆しておくことがより望ましい。   Since the horizontal pipe 11 needs to penetrate the outer wall 3 of the house, it is difficult to set the outer diameter freely, but the vertical pipe 14 and the horizontal pipe 17 are not limited by the outer diameter. For this reason, it is desirable that the vertical tube 14 and the horizontal tube 17 have a double-pipe structure in order to prevent the temperature reduction of exhaust heat to the maximum. Further, since the vertical pipe 14 and the horizontal pipe 17 supply high-temperature exhaust heat to the heat storage space 20 while preventing the temperature reduction of the exhaust heat, the surface of the outer pipe is obtained by making this portion a double pipe. It is more desirable to coat with a heat insulating material such as styrene foam.

縦管１４の上部は風雨に晒されるし、縦管１４の下部と横管１７は地面に埋設され、厳しい寒暖差の環境にある。従って、縦管１４と横管１７は、難錆金属、例えばステンレス鋼材やメッキ仕様の鋼材を使用することが望ましい。また、排熱は、二重管の内管だけに通しても良いが、内管と外管の隙間が大きい場合もあるので、両者を区別せず内管と外管の隙間にも排熱を通して構わない。灯油ストーブ２の排熱を蓄熱空間２０に良好に送り込むため、内管または外管の内径は、少なくとも１０ｃｍ程度に設定することが望ましい。   The upper part of the vertical pipe 14 is exposed to wind and rain, and the lower part of the vertical pipe 14 and the horizontal pipe 17 are buried in the ground, and there is a severe temperature difference environment. Therefore, it is desirable that the vertical tube 14 and the horizontal tube 17 use a rust-resistant metal, for example, a stainless steel material or a steel material with plating specifications. The exhaust heat may be passed only through the inner pipe of the double pipe, but there may be a large gap between the inner pipe and the outer pipe. It doesn't matter through. In order to satisfactorily send the exhaust heat of the kerosene stove 2 to the heat storage space 20, it is desirable to set the inner diameter of the inner tube or the outer tube to at least about 10 cm.

蓄熱空間２０は、一定の深さ、例えば４５〜６０ｃｍの深さに地面を掘り下げて形成する。図２にも示すように、外周には布基礎２８を設け、熱が表層の地面に逃げるのを防止する。   The heat storage space 20 is formed by digging the ground to a certain depth, for example, a depth of 45 to 60 cm. As shown in FIG. 2, a cloth foundation 28 is provided on the outer periphery to prevent heat from escaping to the surface ground.

蓄熱空間２０の底面には、金属、例えば鉄製の中空杭２１を複数打ち込み、切込砕石２２を配置する。なお軟弱地盤の場合はスラブコンクリートを底面に打ってもよい。   A plurality of hollow piles 21 made of metal, for example, iron are driven into the bottom surface of the heat storage space 20, and the cut crushed stone 22 is disposed. In the case of soft ground, slab concrete may be hit on the bottom.

中空杭２１は、孔や開口をもたない密閉型のものを用いることが望ましい。内部にゴミや泥が詰まるのを防止するためである。   As the hollow pile 21, it is desirable to use a sealed type having no holes or openings. This is to prevent clogging of dirt and mud inside.

中空杭２１は、その上部をやや残して、下部を地面下に打ち込む。上部を蓄熱空間２０に露出させることにより、蓄熱空間２０と地面下の地熱との熱交換が良好になるからである。   The hollow pile 21 is driven below the ground with the upper part slightly left. This is because by exposing the upper part to the heat storage space 20, heat exchange between the heat storage space 20 and the geothermal heat below the ground is improved.

露出させる部分の上下寸法は、例えば２０ｃｍ程度とする。中空杭２１の上下寸法は、打ち込み易さを考慮して８０〜１００ｃｍ程度とすることが望ましい。このため地面に打ち込む部分の上下寸法は、切込砕石２２の部分を含めて約６０〜８０ｃｍとなる。この程度の深度に設定しておけば、蓄熱空間２０と地熱との熱交換の良好なバランスを保つことが出来る。   The vertical dimension of the exposed portion is, for example, about 20 cm. The vertical dimension of the hollow pile 21 is preferably about 80 to 100 cm in consideration of ease of driving. For this reason, the vertical dimension of the portion driven into the ground is about 60 to 80 cm including the portion of the cut crushed stone 22. If set to such a depth, a good balance of heat exchange between the heat storage space 20 and the geothermal heat can be maintained.

蓄熱空間２０の上面は、適宜の天板、例えばコンクリート板２４を配して路面とする。このコンクリート板２４等の天板を下方から支持するため、蓄熱空間２０の底面にはＨ鋼（縦置きと横置きを組み合わせたいわゆるＨ鋼束）２５、２６を設ける。符号２７は、縦置きのＨ鋼２５を配置する台座である。複数配置する縦置きのＨ鋼２５の上部に掛け渡す横置きのＨ鋼２６も、複数設けておくことが望ましい（図２参照）。   An appropriate top plate, for example, a concrete plate 24 is disposed on the upper surface of the heat storage space 20 as a road surface. In order to support the top plate such as the concrete plate 24 from below, H steel (a so-called H steel bundle combining vertical and horizontal placement) 25 and 26 is provided on the bottom surface of the heat storage space 20. The code | symbol 27 is a base which arrange | positions the H steel 25 placed vertically. It is desirable to provide a plurality of horizontally-placed H steels 26 that span the upper part of the vertically placed H-steel 25 (see FIG. 2).

従って、かかる構成によれば、金属製の中空杭２１が、地熱を蓄熱空間２０に伝達するので、灯油ストーブ２の排熱によって蓄熱空間２０の温度は常時高温（例えば２０〜３０℃）を保つことが出来る。２０〜３０℃の温度があれば、コンクリート板２４の上の雪は速やかに融ける。   Therefore, according to this structure, since the metal hollow pile 21 transmits geothermal heat to the heat storage space 20, the temperature of the heat storage space 20 is always kept at a high temperature (for example, 20 to 30 ° C.) by the exhaust heat of the kerosene stove 2. I can do it. If there is a temperature of 20-30 ° C., the snow on the concrete plate 24 will melt quickly.

路面（コンクリート板２４）の雪が融けた後も、灯油ストーブ２からの排熱が送り込まれるが、融雪に関係しない余剰の熱は中空杭２１によって地面下に蓄えられる。この地熱は必要に応じて中空杭２１により蓄熱空間２０に与えられるので、中空杭２１を介した地熱の援助により、蓄熱空間２０の温度は極端な低下をみせず、排熱の供給による速やかな融雪を可能とする。   Even after the snow on the road surface (concrete plate 24) melts, exhaust heat from the kerosene stove 2 is sent, but surplus heat not related to snow melting is stored below the ground by the hollow pile 21. Since this geothermal heat is given to the heat storage space 20 by the hollow pile 21 as needed, the temperature of the heat storage space 20 does not show an extreme decrease with the aid of the geothermal heat through the hollow pile 21, and can be promptly achieved by supplying exhaust heat. Allows snow melting.

また本実施形態では、排熱供給管１０を二重構造とするので、排熱の温度低下は少なく、灯油ストーブ２の排熱を最大限に利用することが出来る。   In this embodiment, since the exhaust heat supply pipe 10 has a double structure, the temperature reduction of the exhaust heat is small and the exhaust heat of the kerosene stove 2 can be utilized to the maximum.

なお、本発明に係る融雪設備は、このような実施形態のものに限定されない。例えば、燃焼装置は、灯油ストーブ２に限らず、給湯装置、ボイラ装置など、住宅、マンション、店舗、病院等において利用される各種の燃焼装置を利用することが出来る。   Note that the snow melting facility according to the present invention is not limited to that of such an embodiment. For example, the combustion apparatus is not limited to the kerosene stove 2, and various combustion apparatuses such as a hot water supply apparatus and a boiler apparatus, which are used in houses, apartments, stores, hospitals, and the like can be used.

金属製の内部中空体は鉄製の中空杭２１である必要はない。中空杭２１を用いれば、打ち込み作業が容易なので工事の効率はよい。しかし、先端が非鋭利な内部中空体（例えば角柱）であっても下端部が地面に深く達していれば、埋設等の手段によって配置することも可能であり、中空杭２１と同様の作用を営む。中空杭２１その他の内部中空体は、８〜１５ｃｍ程度の外径のものを使用することが望ましい。内部の空間容積が大きすぎても速やかな熱伝達が難しいので、外径が２０ｃｍを越えるものを使用するよりは、外径８〜１５ｃｍ程度のものを多数本設ける方が効果的である。   The metal internal hollow body does not need to be the iron hollow pile 21. If the hollow pile 21 is used, since the driving work is easy, the construction efficiency is good. However, even if the tip is a non-sharp internal hollow body (for example, a prism), it can be placed by means such as embedding as long as the lower end reaches deeply into the ground. Run. As for the hollow pile 21 and other internal hollow bodies, it is desirable to use those having an outer diameter of about 8 to 15 cm. Since rapid heat transfer is difficult even if the internal space volume is too large, it is more effective to provide a plurality of ones having an outer diameter of about 8 to 15 cm than to use one having an outer diameter exceeding 20 cm.

蓄熱空間２０の上面に配する天板は、コンクリート板２４に限らず、例えば鋼板を利用できる。鋼板を利用した場合は、その上にアスファルト舗装を施すことが出来、路面の見栄えをより向上させることが可能である。   The top plate disposed on the upper surface of the heat storage space 20 is not limited to the concrete plate 24, and for example, a steel plate can be used. When a steel plate is used, asphalt pavement can be applied thereon, and the appearance of the road surface can be further improved.

排熱解放管５０は、高温の排熱を通すものではないから樹脂管（例えばいわゆる塩ビ管）を用いて構わない。   Since the exhaust heat release pipe 50 does not pass high-temperature exhaust heat, a resin pipe (for example, a so-called vinyl chloride pipe) may be used.

図３に示すように、蓄熱空間２０の内部には、補助熱装置、例えば小型のバーナ装置７０を設けても良い。７２は、バーナ装置７０を配するためのコンクリート製の補助熱室である。すでに述べたように、灯油ストーブ２その他の燃焼装置から排熱の供給を受ける限り、このようなバーナ装置７０は本来不要である。しかしながら、旅行や故障によって燃焼装置が数日間運転されない場合に、蓄熱空間２０の温度を極端に低下させることは好ましくない。そこで、補助的に小型のバーナ装置７０等の補助熱装置を用いて蓄熱空間の温度が低くなったときに、蓄熱空間２０の内部温度を例えば１５℃程度に保つようにしておくことが望ましい。   As shown in FIG. 3, an auxiliary heat device such as a small burner device 70 may be provided inside the heat storage space 20. Reference numeral 72 denotes a concrete auxiliary heat chamber for arranging the burner device 70. As already described, as long as exhaust heat is supplied from the kerosene stove 2 and other combustion devices, such a burner device 70 is essentially unnecessary. However, it is not preferable to extremely reduce the temperature of the heat storage space 20 when the combustion apparatus is not operated for several days due to travel or failure. Therefore, it is desirable to keep the internal temperature of the heat storage space 20 at, for example, about 15 ° C. when the temperature of the heat storage space is lowered by using an auxiliary heat device such as a small burner device 70 as an auxiliary.
