Now it is rotatablely connected.
As shown in figure 4, the axis of each dust-collecting pipe 82 is parallel, can extend up and down；Also, the axis of transmission tube 10 is parallel
In the axis of each dust-collecting pipe 82, the second driving member 101 and transmission tube 10 are coaxial, the first driving member 81 and the dust-collecting pipe 82 locating for it
Coaxially, so that dust-collecting pipe 82 and transmission tube 10 are around the axis revolution extended up and down.
As shown in figure 3, the rotatable anode system of this programme includes at least two rows of anode tube rows 8, with the flowing side of flue gas
To for length direction, using the direction perpendicular to ground as short transverse, perpendicular to the direction of length direction to be width in horizontal plane
Direction is spent, then each anode tube row 8 can be spaced apart in width direction.Meanwhile each anode tube row 8 has been correspondingly connected with one
Transmission tube 10, for realizing the driving to each anode tube row 8.
The rotatable anode system of this programme further includes the transmission shaft 11 connecting with power source 12, between the axial direction of transmission shaft 11
Every being distributed with and 8 transmission tubes 10 that are correspondingly connected with of anode tube row, the i.e. axial direction of the transmission shaft 11 width direction that is in deduster；
At this point, the axial direction of transmission shaft 11 is substantially vertical with transmission tube 10, transmission shaft 11 will be around its horizontal axis (in this reality by connector
Apply in example the axis that corresponding left and right extends) be converted into each transmission tube 10 around the revolution of vertical axis.It is driven by one
The driving of two or more transmission tubes 10 may be implemented in axis 11, and then realizes the driving of two rows of or multiple rows of anode tube row 8.It should
Connector can be gear set, transmission tube 10 is resent to after vertically converting for carrying out driving force, alternatively, connector may be used also
To be the structure types such as universal joint.
To improve the driving reliability to dust-collecting pipe 82, the first driving member is can be set in the upper and lower part of dust-collecting pipe 82
81, to be respectively formed transmission chain in the upper and lower part of anode tube row 8, realize the reliable driving to dust-collecting pipe 82.Correspondingly, it passes
The upper and lower part of dynamic pipe 10 also is provided with the second driving member 101, the first driving member 81 of second driving member 101 and top on top
Transmission cooperation, the second driving member 101 of lower part and the first driving member 81 of lower part are driven and cooperate.Due to each second driving member 101
It is fixed on transmission tube 10, each first driving member 81 is fixed on dust-collecting pipe 82, and transmission tube 10 drives upper and lower part by rotation
Second driving member 101 rotates synchronously, it is ensured that the rotation synchronism of the second driving member 101 of top and the bottom, and then guarantee up and down
The drive coordination of first driving member 81 in portion.
The upper and lower part is in contrast, using the center of dust-collecting pipe 82 in above-below direction as reference, in this
The part more than heart is defined as top, is defined as lower part in center part below.
As shown in figure 5, dust-collecting pipe 82 can be hollow pipe, anode tube row 8 is in the end at flow of flue gas direction both ends with it
Mouth is respectively as inlet and outlet.Wherein, the port in front end is as water outlet, the port conduct in rearmost end
Water inlet, as shown in Figure 4.At this point, the flow direction of water and the flow direction of flue gas are substantially opposite, led to from low-temperature space to high-temperature region
Water is more advantageous to cooling.
Wherein, the inlet temperature of flue gas is generally in 140 degrees centigrades in deduster, by being changed with dust-collecting pipe 82
Heat can make temperature in deduster drop to 110 degrees centigrades, can effectively reduce by about 10% exhaust gas volumn；Due to removing
Space in dirt device be it is certain, but also flue gas flow rate reduces, this is conducive to the dust in flue gas and is put for the exhaust gas volumn of reduction
Electrode 9 is charged, and is trapped by anode tube, and efficiency of dust collection can be effectively improved.
As shown in figure 4, anode tube row 8 further includes several curved pipes 84 and flexible connecting pipe 83, up and down the two of each dust-collecting pipe 82
End is respectively connected with flexible connecting pipe 83, and in upper and lower ends, the adjacent flexible adapter tube 83 in the same end is connected to by curved pipe 84.
Flexible connecting pipe 83 and curved pipe 84 play the role of the adjacent dust-collecting pipe 82 of connection jointly, also, flexible connecting pipe 83 is not with dust-collecting pipe
82 rotations, while not influencing the rotation deashing of dust-collecting pipe 82, it is ensured that the connection sealing of dust-collecting pipe 82 and curved pipe 84.
Meanwhile this programme can also include the monitoring system 13 connecting with 12 signal of power source, as shown in figure 3, the power
Source 12 can be motor, and monitoring system 13 is used to detect the revolving speed etc. of the motor, to control the rotation of dust-collecting pipe 82.
Transmission shaft 11 is driven to rotate as shown in figure 3, this programme controls motor by monitoring system 13, transmission shaft 11 drives more
Transmission tube 10 rotates, and the upper and lower part of transmission tube 10 is equipped with a circle driving cog (i.e. the second driving member 101), and and dust-collecting pipe
82 carry out tooth cooperation transmission, and every transmission tube 10 will drive row's dust-collecting pipe 82 rotation.The diameter of dust-collecting pipe 82 10mm~
The spacing of 100mm, dust-collecting pipe 82 and discharge electrode 9 is in 100mm~400mm, when certain dust is accumulated on the surface of dust-collecting pipe 82
