[0034] The tank body 37c is provided with two pistons 38c, a radar tank position meter 41c, an in-tank pressure sensor 42c, and a sealing mechanism 39c inside;
[0035] The inlet electric regulating valve 36c is connected to one side of the tank body 37c, and the left side of the tank body 37c is connected to the outlet electric regulating valve 43c;
[0036] The piston leveling device 40c is provided on one side of the top of the tank body 37c.
[0037] The radar cabinet position meter 41c and the cabinet internal pressure sensor 42c are connected through a connecting line.
[0038] The buffer gas storage tank 37c is used for balancing the CO2-rich gas pressure and flow, and the tank capacity is designed as 5% of the flue gas inlet flow, and the gas storage pressure is less than 2kPa.
[0039] The inlet electric regulating valve 36c and the outlet electric regulating valve 43c are used for gas filling and discharging.
[0040] Pressure monitoring system
[0041] Firstly, the buffer gas storage tank is equipped with an advanced pressure monitoring system. The system is composed of multiple high-precision pressure sensors distributed in different positions of the gas storage tank, which can accurately detect the pressure values at different positions in the gas storage tank in real time. These sensors transmit the detected pressure data to the central control system to provide basic information for the leveling operation.
[0042] Data analysis and judgment
[0043] After receiving the pressure data from the pressure sensors, the central control system analyzes and processes these data. By comparing the pressure values at different positions, it judges whether there is an imbalance in the pressure in the gas storage tank. If it finds that the pressure difference exceeds the set allowable range, the system will start the leveling operation program.
[0044] Gas regulating device
[0045] The leveling operation is mainly realized through the gas regulating device. These devices usually include regulating valves, flow meters and ventilation pipes, etc. When the system judges that leveling is needed, it will automatically adjust the opening degree of the regulating valve according to the specific situation of the pressure difference to control the inflow and outflow of gas.
[0046] If the pressure in a certain area is too high, the system will open the corresponding regulating valve to guide part of the CO2 gas in that area to the area with lower pressure, thereby achieving pressure balance. At the same time, the flow meter will monitor the gas flow in real time to ensure the accuracy and stability of the adjustment process.
