5, which is located in air hose 2 at weld fumes clarifier 1.
Also connection is connected with multiple flue dust collecting pipes 6 on the side wall of air hose 2, and one end of each flue dust collecting pipe 4 is and wind
The side wall of pipe 2 is connected to connection, and the other end of each flue dust collecting pipe 4 is connected with dust hood 7.In each flue dust collecting pipe 4
It is successively equipped with fire resisting damper 8, motor-driven valve 9 and check valve 10, wherein fire resisting damper 8 is respectively positioned at dust hood,.Each flue dust is received
Blower 11 is also connected with by hose on the side wall of collector 6, hose and 6 junction of flue dust collecting pipe be located at fire resisting damper 8 and
Between motor-driven valve 9, and hose and the inclination of flue dust collecting pipe 6 connect, and flue dust collecting pipe 6 is close to the side of dust hood 7 and the folder of hose
Angle is not more than 45 °.
Temperature dust control system as shown in Figure 3 is equipped on each flue dust collecting pipe 6, dust control system includes
The controller 12 of model AT89Sxx or stm32, signal is connected with temperature sensor 13 on controller 12 and dust concentration passes
Sensor 14, the temperature sensor 13 and dust concentration sensor 14 are located at the air inlet of dust hood 7, and controller 12 is also and electronic
Valve 9 is connected with signal.
In a kind of flue dust collecting processing unit of the present invention, dust hood 7 can capture high-temperature flue gas, and coupled flue dust
High-temperature flue gas is transferred in weld fumes clarifier 1 by collecting pipe 6 and air hose 2 to be purified；After blower 11 is opened, it can guarantee
Negative pressure balancing in dust hood 7 and flue dust collecting pipe 6 prevents the high-temperature flue gas of sucking flue dust collecting pipe 6 or gas gathering mask 7 ease
Out；Fire resisting damper 8 is close mounted in flue dust collecting pipe 6, and fire resisting damper 8 is in open state in the case that soot processing device operates normally,
When temperature is more than 280 DEG C in flue dust collecting pipe 6, fuse sheet fusing, fire resisting damper 8 is automatically closed under the effect of torsional spring power, prevents
