When a highly radioactive storage tank is decommissioned, the organic waste liquid in the tank has been stored for a long time. Due to radionuclide decay, radiation degradation, sedimentation and other reasons, the radioactive characteristics and physical and chemical properties in the tank are complicated, and the internal items are stratified, forming a situation where interface dirt, liquid phase and bottom sediment coexist. Both interface dirt and sediment are solid organic matter. Solid organic dirt is difficult to retrieve due to its viscosity, loose connection, irregular shape, strong radioactivity and other characteristics.

[0028] Embodiment 1

[0029] A stirring and suction device for storing highly radioactive residual organic waste, comprising a processor, a stirring and suction mechanism and a liquid storage trolley mechanism, wherein the stirring and suction mechanism comprises a stirring structure, a switching plate structure and a hollow connection structure, wherein the hollow connection structure is fixedly connected to one end of the stirring structure and the switching plate mechanism respectively, and the other end of the switching plate mechanism is connected to the mechanical arm mechanism, the stirring structure comprises a stirring component and a motor drive component, the motor drive component is movably connected to the stirring component, the processor is connected to the motor drive component, the liquid storage trolley mechanism comprises a mobile trolley, a buffer storage tank, a vacuum pump, an air compressor, an air storage tank, a pressure signal acquisition unit, a liquid level signal acquisition unit, a plurality of electric valves and a recovery storage tank, and the processor is respectively connected to the pressure signal acquisition unit The unit, a liquid level signal acquisition unit, a plurality of electric valves, an air compressor, and a vacuum pump are connected. The pressure signal acquisition unit collects pressure signals and transmits them to the processor. The liquid level signal acquisition unit collects liquid level signals and transmits them to the processor. The processor transmits a drive control signal to the motor drive component. The motor drive component drives the stirring component to stir the residual organic waste in the storage tank based on the drive control signal. The processor controls the vacuum pump to evacuate the buffer storage tank based on the pressure signal, and sucks the residual organic waste in the storage tank into the buffer storage tank by controlling the corresponding electric valve. The processor controls the air compressor and the corresponding electric valve based on the liquid level signal to work and transfer the organic waste in the buffer storage tank to the recovery storage tank.

[0030] Optionally, the motor drive component and the stirring component may be movably connected via a gear structure, so that the motor drive component drives the stirring component to stir the residual organic waste in the storage tank.

[0031] The installation positions of the electric valves are: the connection between the air compressor and the gas inlet end of the gas storage tank and the electric valve is provided between the connection, the connection between the gas outlet end of the gas storage tank and the gas inlet end of the buffer storage tank and the electric valve is provided between the connection, the connection between the vacuum pump and the gas outlet end of the buffer storage tank and the electric valve is provided between the connection, the connection between the liquid inlet end of the buffer storage tank and the stirring and suction mechanism and the electric valve is provided between the connection, and the connection between the liquid outlet end of the buffer storage tank and the liquid inlet end of the recovery storage tank and the electric valve is provided between the connection. It should be noted that the above-mentioned electric valves can be replaced with manual valves or other valve devices, or the addition of manual valves and other valve devices falls within the protection of the present invention.

[0032] Furthermore, in order to reduce the possible contamination of organic pollutants by substances in the air, an air filter is provided between the air compressor and the gas inlet end of the gas storage tank and between the connections to filter the air to reduce further increase in the degree of contamination by organic pollutants.

[0033] The pressure signal acquisition unit collects pressure signals and transmits them to the processor. The pressure signals include air tank pressure signals and liquid tank pressure signals. The pressure signal acquisition unit includes a first pressure sensor and a second pressure sensor. The processor is connected to the first pressure sensor and the second pressure sensor respectively. The first pressure sensor collects air tank pressure signals and transmits them to the processor. The second pressure sensor collects liquid tank pressure signals and transmits them to the processor. The first pressure sensor is installed on the air tank to collect air tank pressure signals. The second pressure sensor is installed on the buffer storage liquid tank to collect liquid tank pressure signals. The processor controls the working state of the air compressor based on the air tank pressure signal. The processor controls the working state of the vacuum pump based on the liquid tank pressure signal.

[0034] For example, the processor controls the working state of the air compressor based on the air tank pressure signal. When the gas pressure in the air tank starts to increase, the processor transmits an electric valve control signal to the electric valve connected between the air compressor and the gas inlet end of the air tank to control the electric valve to be in an open state. The processor transmits an air compressor control signal to the air compressor to control the air compressor to be in a working state. The first pressure sensor collects the air tank pressure signal and transmits it to the processor. When the air tank pressure signal is greater than or equal to the maximum threshold of the air tank pressure setting, the processor generates an air compressor control signal and an electric valve control signal based on the air tank pressure signal that is greater than or equal to the maximum threshold of the air tank pressure setting to control the air compressor to be in a stopped working state, and controls the electric valve to be in a closed state.

[0035] For example, the processor controls the working state of the vacuum pump based on the liquid tank pressure signal. When the buffer storage liquid tank starts to be vacuumed, the processor transmits an electric valve control signal to the electric valve connected between the vacuum pump and the gas outlet end of the buffer storage liquid tank to control the electric valve to be in an open state. The processor transmits the vacuum pump control signal to the vacuum pump to control the vacuum pump to vacuum the buffer storage liquid tank. When the pressure signal in the buffer storage liquid tank is less than or equal to the minimum threshold value set for the vacuum degree, the processor generates an electric valve control signal and a vacuum pump control signal to control the vacuum pump to be in a stopped state, and controls the electric valve to be in a closed state.

[0036] The liquid level signal acquisition unit includes a first liquid level sensor and a second liquid level sensor. The processor is connected to the first liquid level sensor and the second liquid level sensor respectively. The first liquid level sensor acquires the liquid level signal of the buffer storage tank and transmits it to the processor. The second liquid level sensor acquires the liquid level signal of the recovery storage tank and transmits it to the processor. The first liquid level sensor is installed in the buffer storage tank to acquire the liquid level signal of the buffer storage tank. The second liquid level sensor is installed in the recovery storage tank to acquire the liquid level signal of the recovery storage tank. The processor controls the electric valve between the liquid inlet end of the buffer storage tank and the connection of the stirring and suction mechanism based on the liquid level signal of the buffer storage tank. The processor controls the electric valve between the liquid outlet end of the buffer storage tank and the liquid inlet end of the recovery storage tank based on the liquid level signal of the buffer storage tank or the liquid level signal of the recovery storage tank.

[0037] The processor controls the electric valve between the liquid inlet end of the buffer storage tank and the connection of the stirring and suction mechanism based on the liquid level signal of the buffer storage tank. For example, when the residual organic pollutants in the storage tank are sucked into the buffer storage tank, when the liquid level signal of the buffer storage tank is greater than or equal to the maximum threshold of the liquid level setting, the processor generates the electric valve control signal based on the liquid level signal of the buffer storage tank greater than or equal to the maximum threshold of the liquid level setting, so as to control the electric valve between the liquid inlet end of the buffer storage tank and the connection of the stirring and suction mechanism to be in a closed state.

[0038] The processor controls the electric valve between the liquid outlet of the buffer storage tank and the liquid inlet of the recovery storage tank based on the liquid level signal of the buffer storage tank or / and the liquid level signal of the recovery storage tank. For example, the organic pollutants in the buffer storage tank are transmitted to the recovery storage tank, and when the liquid level signal of the buffer storage tank is less than the minimum threshold value of the liquid level setting, or when the liquid level signal of the recovery storage tank is greater than or equal to the maximum threshold value of the liquid level setting, the processor generates an electric valve control signal to control the electric valve between the liquid outlet of the buffer storage tank and the liquid inlet of the recovery storage tank.

[0039] Recovery process of organic pollutants: the processor transmits a drive control signal to the motor drive component. The motor drive component drives the stirring component to stir the residual organic pollutants in the storage tank based on the drive control signal. The processor controls the vacuum pump and the corresponding electric valve to vacuum the buffer storage liquid tank. After the vacuum is completed, the residual organic pollutants in the storage tank are sucked into the buffer storage liquid tank by controlling the corresponding electric valve. The processor controls the air compressor and the corresponding electric valve to work and transfer the organic pollutants in the buffer storage liquid tank to the recovery storage liquid tank.

[0040] Furthermore, in order to speed up the recovery efficiency of organic waste, an electric valve is provided between the gas outlet end of the gas storage tank and the gas inlet end of the recovery storage liquid tank and between the connections. The processor controls the air compressor and the corresponding electric valve based on the liquid level signal to operate, so as to quickly transfer the organic waste in the recovery storage liquid tank to the organic waste storage point.
