本発明は、大気圧と同程度の低圧蒸気を直接被加熱流体
に投入する加熱装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heating device that directly injects low-pressure steam comparable to atmospheric pressure into a fluid to be heated.
従釆、被加熱流体を、低圧蒸気で加熱する場合、直接伝
熱する方法と、間接伝熱する方法の２通りある。When heating a fluid to be heated with low-pressure steam, there are two methods: direct heat transfer and indirect heat transfer.
前者の場合、例えばェジェクタータィプの加熱器では、
ノズルを高流速で通過させる為、圧力損失が大きく、大
容量の流体を加熱するには、通さない。また、流体も、
低粘度の例えば水等に限られる。又、バロメトリツクコ
ンデンサー等を使用する場合、設備費が高く、又、スケ
ーリング性の高濃度のスラリ一等を被加熱物とした場合
に、スケ−ルが発生し易く、スケール除去の為の費用も
かかり実用的でない。In the former case, for example, with an ejector type heater,
Since the nozzle passes through the nozzle at a high flow rate, there is a large pressure loss, so it is not recommended to heat a large volume of fluid. Also, the fluid
Limited to low viscosity materials such as water. In addition, when using a barometric condenser, etc., the equipment cost is high, and when a highly concentrated slurry with scaling properties is used as the heated object, scale is likely to occur, and the cost for removing scale is high. It is expensive and not practical.
後者の場合、蒸気を投入できない流体の場はやむをえな
いが、それ以外の流体では、一般に、低庄蒸気の為、被
加熱流体との温度差が少なく、かなりの伝熱面積が必要
となり、設備費が非常に高いし、大気圧以下の低圧蒸気
の場合には真空装置も必要とする。In the latter case, it is unavoidable that the fluid cannot be injected with steam, but other fluids are generally low-voltage steam, so the temperature difference with the fluid to be heated is small, and a considerable heat transfer area is required, which reduces equipment costs. is very high, and in the case of low-pressure steam below atmospheric pressure, a vacuum device is also required.
本発明は上述の問題点に鑑みてなされたもので、低圧蒸

低圧蒸気による直接加熱装置である。The structure of the present invention for achieving this purpose is characterized by a perforated tube with a low temperature fluid inlet pipe connected to one end and a heated fluid outlet pipe connected to the other end, with multiple perforations in the side surface. ,
A sealed inner cylinder with a fluid passage formed inside the perforated cylinder, and a sealed outer cylinder with a steam inlet pipe connected to the cylinder and a steam passage formed on the outer side of the perforated cylinder and enclosed. This is a direct heating device using low pressure steam consisting of a cylinder and a cylinder.
以下図面に示す実施例に基づき本発明を詳述する。The present invention will be described in detail below based on embodiments shown in the drawings.
第１図は本発明による装置の断面的説明図である。１は
多孔筒で、側面部に多数穿孔ｌａを穿設し、多孔筒の一
端部に低温流体入口管４と池端部に加熱流体出口管５を
夫々接続してある。FIG. 1 is a cross-sectional illustration of a device according to the invention. Reference numeral 1 denotes a perforated cylinder with a number of perforations la formed in its side surface, and a cold fluid inlet pipe 4 and a heated fluid outlet pipe 5 are connected to one end and the end of the pond, respectively.

るが、１０〜１００肋程度が好ましい。The size and number of the perforations la are determined by experiments based on the type of fluid and the amount of steam, but the appropriate hole diameter is 1 to IQ. A fluid passage 7 is formed inside the porous tube 1, and a sealed inner tube 2 is supported and housed in the porous tube 1. Both ends of the inner cylinder 2 form a conical body and constitute a flow straightening section 2a. The fluid flowing through the fluid passage 7 is in the form of a thin film, and the thickness of the film varies depending on the flow rate and the type of fluid, but is preferably about 10 to 100 ribs.
３は外筒であり、外筒筒体の側面部に蒸気入口管６を接
続し、外筒３は多孔筒１の外側面部に蒸気通路８を形成
して囲線させる。Reference numeral 3 denotes an outer cylinder, and a steam inlet pipe 6 is connected to the side surface of the outer cylinder body, and the outer cylinder 3 forms a steam passage 8 on the outer side surface of the porous cylinder 1 and surrounds it.

入される。Thus, both ends of the outer cylinder 3 form flange parts 3b and are removably sealed. Although not shown, the porous tube 1 is also configured such that the inner tube 2 can be attached to and removed from the porous tube 1. The low-pressure steam passes through the steam inlet pipe 6 and the steam passage 8, passes through the many perforations la of the porous cylinder 1, flows through the fluid passage 7, and is mixed with the low-temperature fluid.
流体通路７を流通する流体は、フィルム状で流速が大き

、本発明に係る装置が、多孔筒１の内部に密封内筒２を

ィルム状になることにより構成される。The fluid flowing through the fluid passage 7 is in the form of a film, has a high flow rate, and has a reduced pressure to the extent that low-pressure steam can be mixed into the fluid. The steam mixed into the fluid diffuses quickly into the fluid because the fluid is film-like and has a high flow rate, so the fluid can be heated extremely efficiently. This effect is particularly large when the viscosity of the fluid to be heated is high. These effects are achieved by the device according to the present invention housing the sealed inner tube 2 inside the porous tube 1, so that the fluid flowing through the fluid passage 7 becomes film-like.
