Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field The present invention is a method for storing a hollow drum in which a medium to be heated or to be heated is inserted in an outer can, and to heat a fluid or the like to be heated or to be heated by passing a medium through the inside of the outer can. In a device configured to exchange heat with a medium, in particular, a hollow disk for heating or for circulating the medium to be heated is provided protruding from the circumferential surface of the hollow drum, and a hollow disk is provided inside the hollow drum. The present invention relates to a structure of a heat exchanger in which a medium to be heated or heated can be circulated through a drum.

(b) Conventional technology Conventionally, a hollow drum is housed in an outer can, and a medium to be heated or to be heated is caused to flow through the outer can, and a medium to be heated or to be heated is also caused to flow through the hollow drum. Heat exchangers that perform heat exchange are generally available.

In such conventional heat exchangers, the efficiency of heat exchange between the rotating hollow drum and the inside of the outer can is poor, and in order to increase the surface area of the hollow drum, protruding fins or arms are provided, or a structure that stirs the inside of the outer can is required. However, since heat exchange efficiency factors other than the heat transfer area from the hollow drum were not taken into account, heat could not be exchanged evenly from inside the outer can, resulting in a significant drop in heat exchange efficiency.

(c) Problems to be Solved by the Invention As described above, in conventional heat exchangers, fins or arms are protruded on the circumferential surface of the hollow drum in order to improve the efficiency of heat exchange between the inside of the outer can and the hollow drum. However, the improvement of heat exchange efficiency is not solved only by increasing the surface area with such fins and arms, stirring operation, etc., but also by increasing the heat transfer area of the heating or heating medium flow path. It has to be made large, and conventional heat exchangers have not taken sufficient consideration to this point.

(d) Means for Solving the Problems The present invention rotatably accommodates a hollow drum through which a medium to be heated or a heating medium can flow through inside a cylindrical outer can, and a hollow drum inside the outer periphery of the hollow drum. A large number of hollow disks each forming a heat medium circulation path are provided protrudingly, and the inside of the hollow drum is partitioned in the longitudinal direction by a vertical partition wall, and a long heat medium supply path and heat medium having approximately the same length as the hollow drum are provided. Relating to the structure of a heat exchanger in which a discharge passage is formed and the inflow end and outflow end of the heat medium circulation passage of each hollow disk are directly connected to the heat medium supply passage and the heat medium discharge passage, respectively. It is something.

(E) Functions and Effects In this invention, if the hollow drum is rotated while the medium to be heated or to be heated flows into the outer can from the inlet, heat exchange with the medium to be heated or to be heated flowing through the hollow drum is possible. In particular,
The heat medium flows into the hollow disk from the heat medium supply path of the rotating hollow drum, circulates inside the hollow disk, and is discharged to the heat medium discharge path of the hollow drum, smoothly flowing through the hollow disk. The heat exchange efficiency is improved by making the heat transfer area as large as possible between the heating or heating medium and the heating or heating medium inside the outer can.

According to this invention, a hollow disk is provided protruding from the outer periphery of a rotating hollow drum, and the heat medium supply path and the heat medium discharge path formed in the hollow drum are communicated with the heat medium circulation path of the hollow disk. By circulating the heating medium from the hollow drum or the medium to be heated through the heat medium circulation path of the hollow disk, there is an effect that the heat exchange rate can be dramatically increased.

Furthermore, in the present invention, the inflow end and outflow end of the heat medium circulation path of each hollow disk are directly communicated with the heat medium supply path and the heat medium discharge path, respectively, so that the heat that has been supplied is The medium can be simultaneously supplied from the heat medium supply path into a large number of hollow drums, and the heat medium after heat exchange can be discharged from the hollow drums to the heat medium discharge path at the same time, so that the heat exchange rate per unit time is reduced. The amount of heat medium supplied to the vessel can be increased, and large-scale processing becomes possible.

In addition, since the supplied heat medium can be simultaneously supplied into multiple hollow drums from the heat medium supply path, the surface temperature of the hollow drums can be made uniform over the entire length of the heat exchanger. Uniform heating with no differences can be performed, improving product quality.
