[0023] A duct protection net 14 is installed at one end of the air inlet duct 2 and the exhaust duct 3 to prevent large particles of foreign matter from entering the equipment and damaging the equipment.
[0024] A push-pull handle 8 is installed at one end of the device body 1 .
[0025] A desiccant wheel 19 and an iodine adsorbent wheel 20 are provided inside the wheel box 7 .
[0026] The air filter box 4, the surface cooler box 5, the air inlet fan box 6, the rotor box 7, the heating fan box 10, the electric control box 12, and the heat exchanger box 17 are all equipped with box doors by means of rubber-headed hand screws. When a device fails, the corresponding box door can be opened at any time for maintenance.
[0027] The water tank 18 is installed on the device body 1 through a slide rail. The top of the water tank 18 is the heat exchanger chassis 17. A handle is installed on the front of the water tank 18. A water level sensor is installed inside the water tank 18 to detect the water level of the equipment water tank and prompt processing and replacement in time.
[0028] The air filter box 4, the surface cooler box 5, the air intake fan box 6, and the rotor box 7 are all equipped with pressure difference sensors; the PLC control system determines whether each component of the equipment is operating normally according to the data changes. If a fault occurs, the fault location is determined according to the pressure difference data;
[0029] Temperature sensors are installed in the heater 9, the cooler box 5 and the heat exchanger box 17, and temperature and humidity sensors are installed inside the air inlet duct 2 and the exhaust duct 3; the temperature sensor detects the heater outlet temperature, the cooler outlet temperature, the exhaust duct temperature, and the heat exchanger temperature, and adjusts the heater power according to the heater temperature to maintain the temperature at (120-125°C), adjusts the compressor power according to the heat exchanger temperature to maintain the heat exchanger temperature at (2-15°C), and detects whether the filter element releases heat seriously due to adsorption according to the exhaust duct temperature, and adjusts the wheel rotation speed in time.
[0030] Working principle: A miniaturized intelligent detritiation device. Place the air inlet duct 2 at the position where detritiation and iodine removal are required. Turn on the equipment. The gas first passes through the duct protection net 14 on the air inlet duct 2 to remove large particles. Then, it passes through the air filter in the air filter box 4 to remove small particles to prevent clogging of the desiccant wheel 19 and the iodine adsorbent wheel 20. The gas is pre-cooled by the surface cooler in the surface cooler box 5. The gas temperature is controlled at 15-30°C, so that the gas is more easily adsorbed in the wheel. The air inlet fan in the air inlet fan box 6 provides airflow power. The desiccant wheel 19 is used to remove tritium water vapor and keep the gas dry, which is beneficial to the next step of iodine removal and prevents water vapor from interfering with the iodine removal efficiency. The iodine in the gas is removed by passing through the iodine adsorbent wheel 20, and the clean gas is discharged through the exhaust duct 3.
[0031] The desiccant wheel 19 and the iodine adsorbent wheel 20 are driven by a motor and rotate at a constant angular velocity (15 degrees / s-40 degrees / s).
[0032] The rotor that adsorbs tritium water vapor rotates to the upper part of the equipment for desorption. The heating fan in the heating fan box 10 provides the power for the analysis airflow. The desorbed gas is heated to a temperature (120-125°C) by the heater 9 to back-blow the desiccant rotor 19 and the iodine adsorbent rotor 20. The hot air flow brings the tritium water vapor out of the rotor and enters the heat exchanger in the heat exchanger box 17 to condense into liquid tritium water. The liquid tritium water is stored in the water tank 18 through a pipeline. After the water tank 18 is filled with water, the handle is pulled and the water tank moves out along the slide rail. The empty water tank 18 can be pushed back.
[0033] The equipment adopts PLC control system and RS485 interface. The sensor signals involve 12 analog signals, including the temperature of the detritium zone of the rotor, the temperature of the regeneration zone of the rotor, the temperature of the surface cooling section, the temperature of the heater, the temperature of the heat exchange zone, the humidity of the air inlet, the humidity of the exhaust port, the humidity of the heat exchanger, the air inlet wind speed, the wind speed of the surface cooling section, the wind speed of the rotor zone and the wind speed of the exhaust port. Multiple sensor signals are connected to the same bus through the serial communication interface, and a unique address is assigned to each sensor. Different sensors are identified by the address, and the bus communication program is written in the control system. The error detection and correction mechanism is introduced to improve reliability; when multiple devices share the same bus, communication conflicts may occur. Appropriate protocols or mechanisms are adopted, and RS-485 time intervals are used to handle communication conflicts. Appropriate delays are introduced to reduce the possibility of conflicts. At the same time, a certain time interval can also reduce the amount of data processed by the PLC control system. The wireless communication module adopts a full-network wireless data terminal.
[0034] After the detritium removal equipment is powered on, the login password can be entered to start the equipment. First, turn on the temperature, humidity, dose and wind speed detection modules to determine whether the equipment is in normal condition. The equipment can be started when the water level of the detritium removal equipment tank is lower than 80%, otherwise an alarm prompt will be issued. Turn on the detritium removal equipment fan, rotor and heater fan in turn. When the wind speed of the heater fan is higher than 6m / h, turn on the heater to prevent the heater from being damaged due to excessive temperature. The heater outlet temperature is maintained at 120-125℃ for the regeneration of the rotor detritium function. When the temperature of the heat exchange condensation area is higher than 10℃, the first-gear compressor refrigeration is turned on, and when the temperature is higher than 15℃, the second-gear compressor refrigeration is turned on. The logic is to turn on step by step from the first gear to prevent the heat exchange condensation area temperature from being higher than 15℃ and jumping to start the second-gear compression refrigeration directly. The rotor detritium removal area and regeneration area are equipped with temperature sensors to judge the working status of the rotor in real time. The heat exchange condensation area has humidity detection and dose detection as redundant safety judgment to prevent residual radioactive substances. The humidity detection of the air inlet and exhaust port of the detritium removal equipment is used to measure the humidity of the environment to be detritium removed and the working efficiency of the equipment. Wind speed detection is set at the air inlet, surface cooling section, front and rear of the rotor and exhaust port to detect the operating status of the detritium removal channel in real time. When a fault occurs, the blockage position can be determined by the change in wind speed for fixed-point maintenance, such as blockage of the surface cooler or breakage of the rotor desiccant causing blockage of the rotor channel. If the water level of the water tank is higher than 80% during the operation of the detritium removal equipment, an alarm prompt will be issued, and if the water level is higher than 90%, the shutdown procedure will be automatically started. When shutting down, the fan of the detritium removal equipment is first turned off, the heater is turned off when the RH of the heat exchanger is lower than 10%, and the heater fan is turned off when the temperature of the heater outlet is lower than 35℃, and then the compressor and the rotor are turned off in turn and the water tank is prompted to be processed. When the machine is turned on again, if the water level of the water tank is higher than 80%, the equipment alarm prompts and the machine is prohibited from starting. The wind speed, temperature and humidity of the detritium removal equipment are collected by sensors and processed by the PLC control system and issued commands. All data is transmitted to the host computer via the wireless 4G network for viewing and control at any time. The detritium removal equipment runs from startup to shutdown as a complete operation, and the system packages and stores the data of each operation.
[0035] The device login interface and operation interface, after the device is powered on, enter the control interface with the correct user name and password. The device interface displays the operating status of the compressor, heat exchanger, heater, cooler, fan and impeller. When the component status is normal, it displays a blue background. When the component cannot operate normally, it displays an abnormality with a red background and issues an alarm. Click the corresponding component button to jump to the historical operation data parameter interface corresponding to the component. The left side of the interface is the start button and emergency stop. The device automatically records the operating time.
[0036] The above embodiments only express the implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
