Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses atomic scan number 53. as a chemical analysis for diagnosing diseases such as kidney disease and liver disease and detecting disease conditions in hospitals, clinics, health centers, etc. Blood (plasma, blood semen) Radioactive analysis is performed to qualitatively and quantitatively determine the amount of hormones contained in Naka-ku, and it relates to a high-frequency heating concentrator that concentrates the radioactive waste liquid that is left as a result.

These radioactive waste liquids can be disposed of without permission, but they have to be stored strictly during the wave period, and the amount generated per year is a huge amount, so storage space is limited. They were having trouble securing and handling them.

However, as a result of Yuzu's experiments and research, the conventional theory was that the radioactive material 1125 contained in the radioactive waste would be extinguished by heating and dissipated into the atmosphere. It was discovered that the components in the radioactive waste liquid crystallize into a gel and are not released into the atmosphere. It has also been confirmed that the solid matter contained in the radioactive waste liquid is approximately 4 grams in width.

Based on this point, the applicant has already
Although we have developed a method and device for water fractionation of radioactive waste liquid as described in Publication No. 3798, the mechanism and structure are complicated and the entire system suffers a great deal of damage, especially the operation of extracting concentrated waste liquid from the concentration tank and the problem of the concentration tank itself. It had problems such as difficulty in ff#.

In view of the shortcomings of conventional devices that use electric heater heating, the present invention aims to provide a high-frequency heating concentrator for radioactive waste liquid that uses high-frequency heating to simplify the structure and facilitate handling.

Embodiments of the present invention will be described with reference to FIGS. 1 to 4. FIG.

The high-frequency heating concentrator A of the present invention includes an oven λ installed inside the frame, a microwave oscillator placed on the top plate 3 of the frame, and an oven λ and the microwave oscillator ≠.
isolator 6 inserted in the middle of waveguide j connecting
and 1. It consists of a slide 7 that is separately placed near the frame and adjusts the high frequency output of the microwave oscillator.

The above-mentioned oven has a shell-like window in the center area, a wire mesh plate is stretched over it, and a handle 10 is protruded from the left side of the front door.The right edge of the front door is hinged with a hinge 2 so that it can be opened on one side. When the whistle is closed, the front door// has a pair of upper and lower latches on the left side edge/3. ／≠ is formed so that it can be restrained freely, while the ceiling ／! A radiation port/6 at one end of the waveguide j is opened in the center of the waveguide j, and a motor shaft/7 is set upside down on the ceiling/evening surface adjacent to the front side of the radiation port 16, and the motor shaft/7 is connected to the ceiling/j. A stirrer fan /9 is suspended from the lower end, and an oven interior illumination light 20f extends outward along the front edge of the ceiling /j, and an illumination case / that extends downward.

The microwave oscillator≠ is operated from the front, *Kaku panel 2

Since the present invention is configured as described above, first, the present invention apparatus A
Before starting operation, fill the radioactive waste liquid α and close the cap a.
Separately prepare and place a sealed container made of polyethylene or other thermoplastic glass in a glass receiver C, and place it in the latch/3. /Untie the lid, grasp the handle 10, and put it in front of you.

Next, operate the Slidac 7 in the same manner as before to set the high frequency of the microwave oscillator t. After setting the frequency output and confirming that the standby lamp 3/ is lit, press the on push button switch to drive the motor 7 and rotate the stirrer fan at a constant speed, and the microwave oscillator ≠
starts oscillating the high frequency of the set frequency, 4 waves%', 5'
The radioactive waste liquid α in the filling container is irradiated through the radiation port /6. At that time, the p high frequency is turned into an oven by the rotation of the stirrer fan. Stir evenly within the container.

Due to this high frequency, the radioactive waste liquid α is subjected to the frequency heating action and releases moisture, and is then placed in the oven λ.
Then, it moves to the outside of the oven λ and transpires, and the radiation 19E dissipates αQjθ (first, it enters the production state).

During this time, the dispersal staff was monitoring the hour meter 3 and the anode monitor 1-, and after touching the critical force Q1, the radioactive waste liquid α reached the completely concentrated stage where water (il- evaporated and crystallized). After pressing the off button switch 30 to stop the operation of the microwave oscillator and stop the rotation of the stirrer fan, release the latch /3.
By grasping I and pulling forward with one thousand hands, the front n// will be opened to one side, and the glass receiver C and the filling container will be taken out of the refrigerator and the concentration work will be completed.

In this way, the work of concentrating the radioactive waste liquid α is simplified by the device A of the present invention, which requires only 1111 operations compared to the conventional device. When a certain radioactive waste liquid α is saturated to the extent that it cannot absorb the high frequency V, it causes a further frequency reflection f and causes a backflow from the radiation port /6 into the waveguide j.The isolator 6 prevents the backflow and the microwave It has been devised so as not to have a negative effect on the oscillator.

Furthermore, the container I-1 for filling the radioactive waste liquid α is made of thermoplastic plastic with a heat-resistant temperature limit of about 70°C to prevent the radioactive waste liquid α from flying away during heating, and it is stored in a glass receiver C. During heating, in the unlikely event that the container is heated beyond the heat-resistant temperature limit, the filling container will be used as a support in case it becomes distorted, and it will be able to catch the radioactive waste liquid α if it breaks. .

Then, the filled container was removed from the oven and the opening b1 was screwed and sealed with a cap (7).It was stored in the radioactive waste storage room (-1) and heated after the radioactivity was reduced. As the radioactive waste liquid is softened and compacted for disposal, the original volume of the radioactive waste liquid can be reduced several times, which dramatically improves handling and reduces the size of the storage space.
