[0004] One is the improvement of national standards, which makes the design standard of the electrostatic precipitator that meets the standard discharge lower than the current standard, and cannot meet the discharge standard;

[0005] Second, the complexity of working conditions in various industries (mainly due to the increase in specific resistance caused by changes in kiln raw materials) has changed the original design parameters (worsened working conditions), resulting in a larger selection of the original approach speed and a relatively large dust collection area. Shrunken, the dust collector cannot meet the discharge standard;

[0006] Third, due to the popularization of conventional electrostatic precipitator technology in recent years, in order to squeeze into the electric precipitator industry, some small manufacturers have slapped prices on each other, viciously competed, and arbitrarily selected the driving speed without considering the nature of the dust, greatly reducing the dust collection area and circulatio...

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] like figure 1 As shown, the differential mobile horizontal electrode electrostatic precipitator according to the present invention mainly includes a bottom steel frame 1, an ash bucket 2, an ash bucket baffle plate 3, an inlet head 4, an inlet airflow uniform distribution 5, and an anode plate toggle Device 6, anode system 7, cathode system 8, cathode top rapping system 9, casing 10, top cover 11, outlet head 12 and outlet groove plate 13, wherein:

[0028] The bottom steel frame 1 supports the upper shell 10, the two ends of the shell 10 are provided with an inlet head 4 and an outlet head 12, and the lower part is provided with an ash bucket 2, and the ash bucket 2 is equipped with an ash bucket baffle 3, and the inlet head 4 is equipped with an inlet airflow uniform distribution device 5, which can make the flue gas evenly distributed in the box, the ash collection load deviation of each anode plate is small, and the utilization rate of the electric field is improved. The outlet head 12 is provided with an outlet groove plate 13 .

[0029] The housing 10 is provided with an anode plate toggle device 6, an anode system 7, a cathode system 8, and a cathode rapping device 9. The anode system 7 is a plurality of ring-shaped anode rows arranged vertically and equidistantly. The device is driven to move circularly, and an anode plate toggle device 6 for vibrating and cleaning dust is provided at the bottom of each anode row. The cathode system 8 and the anode system 7 form a number of equal-spaced, parallel and alternately arranged groups perpendicular to the A moving differential electric field in the direction of the airflow. A cathode rapping device 9 is provided on the top of the cathode system, and the cathode rapping adopts top electromagnetic rapping technology.

[0030] like figure 2 , the anode system 7 and the cathode system 8 are alternately arranged at equal intervals. The anode plates installed on the anode system 7 form several equidistant differential channels for flue gas to pass through.

[0031] like image 3 , each annular anode row includes a group of anode plates 14 and connectors 16, each anode plate 14 is distributed and arranged on each connector 16 parallel to the horizontal plane, a group of connectors 16 are connected in series to form an endless chain and connected to the transmission, and Driven by the transmission mechanism 15, it moves at a uniform speed from top to bottom or from bottom to top. The sectional shape of the anode plate can be square tube, rectangular tube, circular, Z-shaped, S-shaped, I-shaped, V-shaped, or C-shaped. The material of the anode plate 14 can be common cold-rolled plate, various stainless steels and various conductive composite materials. The spacing between the anode plates arranged at equal intervals is 20mm~60mm.

[0032] Connector 16 is connected with the transmission sprocket in the transmission device, and the transmission chain plate matched with the transmission sprocket is connected as a whole by a pin shaft, and then connected with the upper and lower transmission sprockets. The two ends of the shaft pass through the shell, are connected with the bearings on both sides, and the shaft head on one side is connected with the driving device. The lower sprocket is installed on the driven shaft, and the driven shaft is supported by bearings in the dust inside the electric field.

[0033] like Figure 4 , the anode plate toggle device 6 is installed at the lower end of the anode system 7 .

[0034] like Figure 5 , the transmission mechanism 15 is provided with several groups of transmission shafts 17 and driven shafts 18 inside the housing, and each of the transmission shafts 17 and the driven shafts 18 is equipped with a pair of transmission sprockets 19 that drive the anode plate 14 to move. The casing 10 is connected with the external speed regulating sprocket set 20 .

[0035] like Image 6 , the anode plate toggle device 6 is wear-resistant casing 21 arranged at equal intervals, each wear-resistant casing 21 is installed on the connecting shaft 22, and the connecting shaft is installed on the bearing 23 in the dust arranged at equidistant, and passes through the housing 10 is connected with driving motor.

[0036] The invention integrates the moving electrode technology and the differential electric field technology, which not only ensures a good dust cleaning effect, but also greatly increases the dust collection area of the single electric field. At the same time, the width of the differential channel is 20mm-60mm, which greatly reduces the migration distance of the charged dust particles adsorbed to the horizontal anode plate, and the electric field force on the dust particles is also enhanced by the square multiple, and the dust driving speed is also quadratically multiplied. improve.

[0037] When the flue gas enters the slow-moving differential channel, due to the diversion and blocking effects of the differential channel, the airflow is divided into several approximately laminar flow fields, and the uniformity of the airflow distribution is greatly improved. Moreover, due to the anode plate and cathode The lines are arranged perpendicular to the direction of the airflow, and the direction of the generated electric field lines is parallel to the flow direction of the flue gas. In a true sense, the electric field is consistent with the flow field.

[0038] The anode plate adopts the self-vibrating mode of the plate, that is, no instantaneous rapping force is given to the plate from the outside, but the vibration force is generated by the deformation of the plate itself when the plate moves to compress the plate toggle mechanism. The anode plate is driven by the transmission chain plate to move periodically. When the anode plate moves to the action area of the pole plate toggle device, due to the continuous pressure of the wear-resistant sleeve, the surface of the pole plate has a certain deformation. When the pole plate finally leaves the wear-resistant sleeve When the pressure disappears, the deformation becomes restored, and the energy accumulated in the deformation is released in the form of vibration, achieving the effect of cleaning the plate and dust. At the same time, since the dust cleaning process of each plate is carried out at the bottom of the electric field, the secondary dust during rapping is completely eliminated, ensuring the long-term stable presentation of high dust removal efficiency.

[0039] There are many specific application approaches of the present invention, and the above description is only a preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, some improvements can also be made without departing from the principles of the present invention. Improvements should also be regarded as the protection scope of the present invention.
