Abstract
Description
Technical Field
[0001] The present invention belongs to the field of medical shelters, and particularly relates to a medical nuclear sewage storage shelter. Background Art
[0002] Medical nuclear wastewater mainly refers to the radioactive nuclides used in the process of nuclear medicine diagnosis and treatment and the wastewater generated by laboratory experiments, which involves the process of using radioactive isotopes for diagnosis and treatment. Radioactive isotope treatment equipment: In the nuclear medicine department, radioactive isotopes used to treat diseases such as tumors, such as iodine-131 (I-131), strontium-89 (Sr-89), etc. After patients take or inject these isotopes, excreta containing radioactive substances will be produced; Radioactive isotope diagnostic equipment: For example, technetium-99m (Tc-99m) used in SPECT / CT (ECT), fluorine-18 (F-18) used in PET / CT. When these equipment are used for diagnosis, radioactive wastewater will also be generated. Traditional hospitals usually build decay pools to collect and store medical nuclear wastewater, and let it decay to a safe level before discharging or subsequent treatment. However, traditional decay pools are immovable and have a long construction period. In case of some sudden events, mobile shelter hospitals need to be set up temporarily to meet medical needs. It is impossible to quickly and safely collect the medical nuclear wastewater generated by the medical equipment used in the shelter hospital, so there is a lack of corresponding mobile decay storage equipment.
[0003] The patent document with the application number "CN202310915174.X" discloses a fully automatic treatment system for nuclear medicine decay pool waste liquid, including: a plurality of decay pools arranged in series, an inlet pipe and an outlet pipe are connected in the decay pool, pumps are provided on the inlet pipe and the outlet pipe, the inlet pipe extends to the bottom of the decay pool, the bottom end of the outlet pipe extends into the upper part of the decay pool, and the inlet pipe is connected to the outlet pipe of the adjacent decay pool; a depth adjustment unit, connected to the top of the decay pool, for adjusting the height of the bottom end of the outlet pipe; a coagulant aid adding unit, connected to the inner wall of the decay pool, for adding coagulant aid into the decay pool. The implementation scheme in this comparative document requires a plurality of decay pools to be arranged in series, and it cannot be quickly realized in a mobile shelter hospital. Therefore, the above technical problems still exist.

[0016] Compared with the existing technology, the present invention has the following beneficial effects:
[0017] 1. In the medical nuclear sewage storage shelter of the present invention, the short half-life tank and the long half-life tank are integrally installed in the outer cabin, and a marble layer and a lead plate layer are placed in the wall of the outer cabin. Barite particles are filled between the outer cabin and each decay pool, so as to effectively isolate radiation and store and decay medical nuclear wastewater.

[0018] 2. In the present invention, the nuclear wastewater is first disinfected by introducing chlorine gas into the disinfection pool through an attached air supply pipeline connected to a high-pressure chlorine gas cylinder, and then air is pressed into the disinfection pool through the main air supply pipeline. The nuclear wastewater is pressed into the short half-life tank and the long half-life tank by air pressure.

The bottoms of the half-life tank and the sedimentation tank in the present invention are both set as slope structures, and spray pipes are respectively installed at the ends of each water outlet pipeline. The spray pipes are located at a higher position at the bottom of the half-life tank, so that a high-pressure jet effect is generated when the water column is injected, thereby self-cleaning the bottom of the half-life tank.

[0049] In addition, the electronic control unit 600 includes a controller and a battery pack. A charging interface 610 is provided on the outside of the battery pack, and a third protection box 620 is installed at the charging interface 610. Both ends of the third protection box 620 can penetrate through the wall of the outer cabin 100, and at the opening of the third protection box 620, a third baffle 621 is installed by bolts.
[0050] Next, the working process of a nuclear sewage storage shelter in this embodiment will be described in detail to enable those skilled in the art to better understand the present invention. The working steps of this water storage shelter are as follows:
[0051] Water inlet: Connect the wastewater pipe to the water inlet end of the water inlet pipeline 430, turn on the water pump 432 and the eighth solenoid valve 431, and pump the nuclear wastewater into the disinfection box 400.
[0052] Disinfection: Close the eighth solenoid valve 431, connect the chlorine gas cylinder to the air inlet, turn on the seventh solenoid valve 711 and the third solenoid valve 411, and let the chlorine gas from the chlorine gas cylinder flow into the disinfection box 400. If the air pressure in the chlorine gas cylinder is insufficient, the air extraction pump 701 and the sixth solenoid valve 702 can be turned on simultaneously to assist in pressurization. At this time, the wastewater in the disinfection box 400 can be disinfected, and the excess gas can flow into the post-treatment box 500 through the first air outlet pipeline 410 for treatment, while ensuring the pressure stability in the disinfection box 400.
[0053] Wastewater retention: When it is necessary to inject waste liquid into the short half-life tank 200, close the seventh solenoid valve 711 and the third solenoid valve 411, open the sixth solenoid valve 702, the first solenoid valve 211, the fourth solenoid valve 221 and the air extraction pump 701 to pressurize the disinfection tank 400, so as to pump the wastewater into the short half-life tank 200 through the first water outlet pipeline 210. The gas discharged from the short half-life tank 200 is introduced into the post-treatment tank 500 through the second air outlet pipeline 220; When it is necessary to inject waste liquid into the long half-life tank 300, close the seventh solenoid valve 711 and the third solenoid valve 411, open the sixth solenoid valve 702, the second solenoid valve 311, the fifth solenoid valve 321 and the air extraction pump 701 to pressurize the disinfection tank 400, so as to pump the wastewater into the long half-life tank 300 through the second water outlet pipeline 310. The gas discharged from the long half-life tank 300 is introduced into the post-treatment tank 500 through the third air outlet pipeline 320;
[0054] Sewage discharge: Taking the short half-life tank 200 as an example when sewage discharge is required, first connect the first sewage discharge pipe 840, and then open the air extraction pump 701, the sixth solenoid valve 702, the third solenoid valve 411 and the fourth solenoid valve 221. First, press some gas into the short half-life tank 200 through the first air outlet pipeline 410 and the second air outlet pipeline 220 to ensure the smooth flow of the wastewater when it flows downward. When the pressure rises to a certain value, open the ninth solenoid valve 841 to make the nuclear wastewater flow out from the first sewage discharge pipe 840 under the condition of a certain air pressure; The principle of sewage discharge of the long half-life tank 300 is similar to that of the short half-life tank 200 and will not be elaborated here.
[0055] In summary, in the medical nuclear sewage storage shelter of the present invention, the short half-life tank 200 and the long half-life tank 300 are integrally installed in the outer cabin 100, and a marble layer 120 and a lead plate layer 130 are placed in the wall of the outer cabin 100. Barite particles are filled between the outer cabin 100 and each decay pool, so as to effectively isolate radiation and store and decay the medical nuclear wastewater. A disinfection tank 400, a post-treatment tank 500 and an electronic control unit 600 with an independent battery pack are also integrally installed in the outer cabin 100, which can independently realize processes such as wastewater collection, disinfection, storage, drainage and post-treatment, and has mobility and can be used in cooperation with mobile cabin hospitals.
