The balance plate 23 can be connected to the support foot 21 by welding or bolts.

[0017] The carbon source storage tank 1 is equipped with a baffle plate 16, which divides the carbon source storage tank 1 into several cavities. The baffle plate 16 has several parallel strip-shaped through holes 19 on its upper or lower sides, forming an S-shaped baffle channel. To facilitate the assembly and disassembly of the baffle plate 16, the carbon source storage tank 1 has limiting grooves 20 on both sides, and the baffle plate 16 is embedded in the limiting grooves 20 on both sides. The bottom of the carbon source storage tank 1 also has a limiting groove 20, and the bottom of the baffle plate 16 is embedded in the limiting groove 20 at the bottom of the carbon source storage tank. The limiting grooves 20 on both sides and the bottom of the carbon source storage tank 1 are integrally formed structures, and the limiting grooves 20 are connected to the inner side of the carbon source storage tank 1 by welding. Fixing is achieved by the engagement of the limiting grooves 20 with the edges of the baffle plate 16. To further improve the reliability of the fixation, connecting ears 18 are provided on both sides of the upper end of the limiting grooves 20 and on the upper side of the baffle plate 16, respectively. The upper end of the limiting grooves 20 is connected to the baffle plate 16. The upper connecting lug 18 is connected by bolts to fix the baffle 16; the connecting lug 18 can be connected to the limiting groove 20 and the baffle 16 by welding; in order to improve the sealing performance, a rubber gasket can be set in the limiting groove 20 in actual use; The upper and lower sides of the two end cavities of the carbon source storage tank 1 are connected by circulation pipes 14. A circulation pump 15 is installed on the circulation pipes 14. Through the circulation pump 15 and the flow-dredging effect of the parallel strip-shaped through holes, as well as the flow-deflecting effect of the baffle plate 16, the uniformity of the carbon source can be ensured. Compared with the traditional built-in stirring paddle, it does not occupy the internal space of the storage tank, which not only reduces power consumption, but also increases the actual volume of the storage tank. The bottom of the end cavity of carbon source storage tank 1 is connected to the upper side of addition storage tank 2 and addition auxiliary storage tank 3 via a first inlet pipe 4 and a second inlet pipe 5, respectively.

Through the connecting pipelines, the carbon source in carbon source storage tank 1 can fill addition storage tank 2 and addition auxiliary storage tank 3 by gravity. It should be noted that the volume settings of addition storage tank 2 and addition auxiliary storage tank 3 should be set according to the actual application requirements. The volume of addition auxiliary storage tank 3 is half that of addition storage tank 2. Addition auxiliary storage tank 3 is used for emergency replenishment when addition storage tank 2 malfunctions. The bottom of addition storage tank 2 and addition auxiliary storage tank 3 are respectively equipped with a first outlet pipe 8 and a second outlet pipe 9 to transport carbon to the addition point. The system is equipped with a first outlet valve 10 and a second outlet valve 11.
