[0022] Lifting ears 13 are installed at the four corners of the top of the equipment body 1, and casters 8 are installed at the four corners of the bottom of the equipment body 1; a push-pull handle 12 is installed in the middle of the other side of the equipment body 1.

[0023] An air filter is installed inside the air filter box 5 , an iodine adsorber is installed inside the iodine adsorption box 6 , and a fan is installed inside the fan box 7 .

[0024] The end faces of the air inlet duct 2 and the air exhaust duct 3 are both installed with duct protection nets 15 to prevent large particles of foreign matter from entering the interior of the equipment and damaging the equipment.

[0025] The sides of the air intake buffer box 4, the air filter box 5, the iodine adsorption box 6, the fan box 7 and the heating box 14 are all equipped with sealed box doors through rubber-head hand screws. When the equipment fails, the corresponding baffles can be opened at any time for maintenance.

[0026] The air filter box 5 and the iodine adsorption box 6 are internally installed with a dose detection sensor, which is used to detect the dose of the air filter and the iodine adsorber. When the dose rate exceeds 50μSv / h, it is prompted to replace the filter element and the fan is prohibited from starting.

[0027] A temperature sensor is installed inside the heating box 14. The temperature sensor is used to detect the temperature of the air outlet of the electric heater. If the outlet temperature exceeds 50°C, all electric heaters are turned off.

[0028] A wind speed sensor is installed inside the air intake buffer box 4 to detect the wind speed in the air intake buffer room of the equipment. When the wind speed is less than 13m·s -1 It is forbidden to start the electric heater. The air filter box 5 and the iodine adsorption box 6 are both equipped with differential pressure transmitters. The differential pressure transmitter detects the differential pressure before and after the air filter and the iodine adsorber. When the differential pressure of the high-efficiency filter and the iodine adsorber reaches 520KPa and 700KPa respectively, it prompts replacement and prohibits starting the fan. The PLC control system determines whether the various components of the equipment are operating normally according to the data changes. If a fault occurs, the fault location is determined according to the differential pressure data. A humidity sensor is installed on the top of the heating box 14. The humidity sensor detects the humidity of the air flow. The equipment turns on the corresponding number of electric heater groups according to the humidity. There are three groups of electric heaters in total. When RH≥50%, three groups of electric heaters are turned on, and when 50≥RH≥35%, two groups of electric heaters are turned on.

[0029] The air inlet duct 2 is connected to the air inlet buffer box 4, the air inlet buffer box 4 is connected to the air filter box 5, the air filter box 5 is connected to the heating box 14, the heating box 14 is connected to the iodine adsorption box 6, the iodine adsorption box 6 is connected to the fan box 7, and the fan box 7 is connected to the exhaust duct interface 9.

[0030] The electric control cabinet 10 is electrically connected to the control panel 11 , the humidity sensor, the wind speed sensor, the pressure difference transmitter, the temperature sensor, the fan, and the electric heater respectively.

[0031] Working principle: An intelligent air purification and iodine removal device, connects the air inlet duct 2 to an external pipe or places it in an environment that requires air purification, turns on the equipment, and the gas first passes through the pipe protective net 15 of the air inlet duct 2 to remove large particles, and then passes through the air intake buffer box 4 to increase the contact area between the airflow and the air filter in the air filter box 5. The gas filtered by the air filter passes through the electric heater in the heating box 14, so that the water in the gas is in a neat form to prevent small water droplets contained in the airflow from interfering with iodine adsorption. The airflow passes through the iodine adsorber in the iodine adsorption box 6 to remove the iodine component. The fan in the fan box 7 is located at the rear side of all filter elements to provide negative pressure to prevent filter element damage. The purified clean gas is discharged through the exhaust duct 3.

[0032] When the trolley is started, the login is verified through the password. After the verification is passed, the trolley can be operated to start. The trolley has three modes: manual mode, remote control and intelligent operation mode. The host computer can intervene in the status of the trolley at any time after logging in through verification. The γ dose rate module detects that the dose rate of the trolley filter exceeds 50μSv / h, prompting the replacement of the filter element and prohibiting the start of the fan. The pressure difference module detects the high-efficiency filter and iodine adsorber of the trolley respectively. When the pressure difference of the high-efficiency filter and the iodine adsorber reaches 520KPa and 700KPa respectively, it prompts replacement and prohibits the start of the fan. The wind speed module detects the pipeline wind speed in real time. When the wind speed is less than 13m·s -1The heater is prohibited from starting when RH≥50%. There are three groups of heaters. When RH≥50%, three groups of heaters are turned on. When 50≥RH≥35%, two groups of electric heaters are turned on. When the outlet temperature of the electric heater exceeds 50℃, all heaters are turned off. The gamma dose rate, temperature and humidity, pipeline pressure difference and wind speed of the car are collected by sensors and processed by the PLC control system and issued commands. All data are transmitted to the host computer through the wireless 4G network for viewing and remote control at any time to realize data interaction between devices. The car is a complete operation from startup to shutdown, and the system packages and stores the data of each operation.

[0033] The trolley operation interface, the main operation interface includes the selection of operation mode, real-time data of the equipment, the operating status of the filter components and the single operation time. The emergency stop function can be enabled when the trolley is in any state. In manual mode, the trolley is controlled by the fan switch and heating switch on the right side of the interface. When switched to intelligent mode, the trolley enters the automatic operation mode, and other operation buttons will turn gray and become invalid. The trolley operation data curve interface mainly includes real-time curves of data such as the status of the high-efficiency filter and iodine adsorber, the trolley dose rate, wind speed and temperature, which shows the changing trend of the data in a single operation of the trolley.

[0034] 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.
