Abstract

PURPOSE:To accelerate an energy-saving operation during the regeneration of adsorbents. CONSTITUTION:There are provided adsorbents 1, a heating source 2 incorporated into the adsorbents 1, a blower 3 for sending air to the adsorbents 1, and an air passage 4 surrounding these items. With this arrangement, when a regeneration process is started, the heating source 2 is actuated. The heating source 2 heats the air introduced by the blower 3 to produce an air flow of high temperature, whereby the adsorbents 1, as a whole, are heated uniformly. On the other hand, the adsorbents 1 situated near the heating source 2 receive radiant heat from the source 2 to be heated. Consequently, the moisture contained in the adsorbents 1 is removed uniformly by means of the high temperature air flow and the radiant heat.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adsorbent reclaiming apparatus which utilizes an adsorbent to save energy and improve efficiency during the regenerating process.

[0002]

2. Description of the Related Art Conventional regeneration of an adsorbent comprises an adsorbent 1, a heater 2, a blower 3, and an air passage 4 surrounding them, as shown in FIG. When the adsorption process is completed, the heater 2 is energized. Then, the air induced by the blower 3 is heated by the heater 2 to become high-temperature air, which heats the adsorbent 1. The radiant energy is also applied to the adsorbent 1 by the heater 2 itself. The energization of the heater 2 was maintained until the adsorbent 1 was regenerated.

[0003]

However, the above configuration has the following problems. The above-mentioned configuration that causes a large amount of heat loss causes the TSA (Thermal Swing Adsor) to desorb the moisture adsorbed on the adsorbent 1 by supplying the adsorbent 1 with the temperature of the air supplied to the adsorbent 1 at a temperature higher than that during the adsorption process.
ption) is adopted. At that time, since the blower 3, the heater 2, and the adsorbent 1 are arranged in this order, the heat exchange loss when the regeneration air is heated by the heater 2 and the heated air that has been heated passes through the air passage 4. There is a heat dissipation loss when doing.
Not only is it necessary to prevent the heater 2 from leaking, which requires reliable heat insulation prevention measures and leakage prevention measures, but the radiant heat from the heater 2 also heats the air passage 4, so the heat insulation prevention measures are required. Regeneration of the adsorbent 1 whose regeneration is inefficient is performed from the upstream side of the blower 3. Therefore, in order to regenerate the downstream side of the adsorbent 1, the upstream adsorbent 1 which has already been regenerated is continuously heated by the heater 2. This heating is completely useless.

The above-mentioned three problems at the time of reproduction increase power consumption, increase running cost,
The initial cost was also increased. The present invention solves the conventional problems, and an object of the present invention is to provide a regeneration technique that consumes less power, has higher regeneration efficiency, and does not require a heat insulating structure.

[0005]

[MEANS FOR SOLVING THE PROBLEMS] An adsorbent provided inside an air passage, a blower for sending air to the adsorbent, and a heating source provided inside the adsorbent are provided.

[0006]

According to the present invention, when the regeneration process is started, the heating source is activated by the above-described structure, and the heating source turns the air induced by the blower into high-temperature air, and the entire adsorbent downstream of the heating source is removed. Heat evenly. The adsorbent is also heated by receiving radiant heat from the heating source. The entire adsorbent is uniformly heated by the warm air and radiant heat, and the moisture contained in the adsorbent is uniformly desorbed.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 is a solid adsorbent formed into a honeycomb shape. Reference numeral 2 is a heating source constituted by connecting an electric heater to the void of the solid adsorbent. A blower 3 is provided upstream of the solid adsorbent 1. 4 is an air course. With the configuration described above, the heating source 2 operates when the regeneration process is started. The heating source 2 turns the air induced by the blower 3 into high-temperature air, and heats the adsorbent 1 near the heating source 2. Further, the adsorbent 1 around the heating source 2 is
It is heated by receiving radiant heat from. The entire adsorbent 1 is heated by the high-temperature air and radiant heat, and moisture in the adsorbent 1 is uniformly desorbed from the entire adsorbent 1. Therefore, the operating time of the heating source 2 can be shortened as compared with the conventional technique. At this time, most of the radiant heat directed to the conventional heating of the air passage 4 heats only the adsorbent 1. Therefore, there is no heat dissipation loss, and it is not necessary to take any heat insulation and leakage prevention measures.

[0008]

As described above, according to the adsorbent regenerating apparatus of the present invention, the following effects can be obtained. By incorporating a heating source inside the adsorbent, there is no heat loss when heating the adsorbent during the regeneration process. Since the entire adsorbent is heated by the heating source, the regeneration time can be shortened without causing unevenness in the regeneration of the adsorbent. Since the heat source is surrounded by the adsorbent, it is not necessary to take heat insulation around the heat source and prevent leakage. Since the adsorbent can be heated uniformly, there is no locally high temperature, and moisture can be adsorbed immediately after the regeneration process. In addition, since it is difficult for the adsorbent to have a locally low portion, the regeneration efficiency is increased.
