Description

Technical Field

[0001] The present invention relates to the field of low emission management technology, and in particular to a low emission management control device for a smart city. Background Art

[0002] In the construction of smart cities, low-emission management and control devices have gradually become one of the key technologies for solving the problem of industrial waste gas emissions. Such devices usually integrate multi-level and multi-functional waste gas treatment systems to control and reduce the concentration of harmful substances in the waste gas in an intelligent way, thereby achieving the goals of high efficiency and low emissions.

[0003] In practice, existing emission management devices mainly rely on a single filter component or a manual adjustment control system, which has some shortcomings.

When the friction plate 519 descends, the squeezing spring 520 can make the bottom end of the friction plate 519 fit the top end of the friction ring 524, thereby changing the damping of the valve 502 when it rotates.

The exhaust gas in the two transmission pipes 4 of the intelligent management and control device body 3 is guided into the three-way pipe 6. When the exhaust gas flow rate is high, its impact force drives the transmission blade 511 to rotate, and the rotation of the transmission blade 511 drives the transmission rod 512 to rotate the transmission disc 513. During the rotation of the transmission disc 513, due to the centrifugal force generated when the transmission disc 513 rotates, multiple transmission blocks 514 can be thrown out, and the transmission blocks 514 rotate with the transmission disc 513. The transmission blocks 514 can be inserted into the transmission groove 509 to drive the transmission plate 505 to move, and the transmission plate 505 pushes the rack 504 to move.
