This is a type of steam pot in which water is filled at the bottom and an electric heater is immersed in the water, and it is necessary to maintain a constant water level at all times. Therefore, when starting up, it is necessary to preheat the water as well as preheating the device, and it takes time to start up. However, in order to make this method quantitative, it is necessary to detect the steam flow rate and water level, which makes the device extremely complicated.
Furthermore, it is not suitable for cases where it is desired to change the steam supply rate in stages during the regeneration process of the adsorbent.

る。 Water (or hot water) pumped up from a water supply tank 11 by a metering pump 12 is vaporized by a steam generator 1 and supplied to a reactor 13 to regenerate solid amine. The steam supply rate is adjusted by a flow controller 14.

を切替える必要がある。 In the example shown in Figure 2, a direct heating regeneration method using steam is used to regenerate the solid amine that has adsorbed CO2 , but the regeneration process of the solid amine involves the heating process of the solid amine and the desorption process of CO2 from the solid amine. It can be divided into two processes. And in order to shorten the regeneration time of solid amine, it is necessary to quickly heat the solid amine to the regeneration temperature and to release CO2 after reaching the regeneration temperature.
Excessive steam is unnecessary, as long as the amount of heat and heat radiation required for desorption is supplied. Therefore, in the heating process of solid amine, a large amount of steam is supplied, and CO 2
During the desorption process, it is necessary to change the steam supply rate to reduce the amount of steam.

よく保持することができる。(Effects of the Invention) According to the present invention, a dry heating heater is installed in a vertical casing, and a gap between the dry heating heater and the vertical casing is filled with a heat transfer medium, which is supplied via a metering pump. Steam is generated by directly heating water with an air-heating heater. As described above, since the present invention employs a direct heating type, the necessary amount of water can be evaporated instantly, and both temperature and flow rate can be maintained accurately without waste.

御系も必要となり、制御系が複雑になる。 Furthermore, if water is supplied at the bottom and steam is extracted from above, the evaporation surface is limited to the bottom. In order to evaporate in a short time and downsize using this method, it is necessary to increase the current density of the heater, but if the current density of the heater is increased, the surface temperature of the heater increases and the heater may break. It causes Therefore, when obtaining steam using this method, it is necessary to immerse the heater in water and constantly radiate heat, and the heater cannot be left unattended. In addition, if you try to obtain a constant flow of steam with such an immersion type steam generator, you first need to detect the water level to prevent dry cooking, and you also need a control system to keep the evaporation rate constant. , the control system becomes complicated.

一定流量の蒸気が得られるようになつた。 On the other hand, in the present invention, since it is not possible to obtain a high current density by using a heater for dry cooking, in order to overcome this drawback, water is supplied from above and steam is taken out from below, so that the heater It became possible to effectively utilize the heat transfer area and achieve compactness. Furthermore, since the supplied water always flows downward,
Since the water evaporates without staying in one place, it is now possible to obtain a constant flow of steam simply by controlling the water metering pump and heater temperature.
