Detailed Description
The invention provides a double-channel electrostatic precipitator, and in order to make the purpose, technical scheme and effect of the invention clearer and clearer, the invention is further described in detail below by referring to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 to 7, the present invention provides a dual-channel electrostatic precipitator. It will be appreciated that the components inside the housing are drawn directly in figure 1 for ease of viewing, and that there is virtually no direct access to these components from outside the housing. The dashed arrows in fig. 1 are shown for gas passing from the first channel and the solid arrows are shown for gas passing from the second channel.
The 4 rows and 5 columns of anode cylinders are drawn in the drawings only for explaining the structural principle and are not intended to limit the specific number of anode cylinders.
Referring to fig. 1 to 3, the two-channel electrostatic precipitator includes a housing, a first air inlet 111 is disposed at a top end of the housing, a first air outlet 112 is disposed at a bottom end of the housing, a second air inlet 121 is disposed at one end of the housing in a horizontal direction, and a second air outlet 122 is disposed at the other end of the housing in the horizontal direction; an anode frame 2 is arranged in the shell, and a first cathode frame 41 is arranged on the anode frame; the anode frame 2 is insulated from the first cathode frame 41; a plurality of rows of anode cylinders 3 (each anode cylinder is preferably a cylinder) are vertically arranged on the anode frame 2, first cathodes 51 which are the same in number as the anode cylinders and correspond to the anode cylinders one by one are arranged on the first cathode frame 41, and each first cathode 51 is respectively inserted into the corresponding anode cylinder 3; a second cathode frame 42 is respectively arranged between any two adjacent rows of anode cylinders, and a plurality of second cathodes 52 are respectively arranged on each second cathode frame 42; the top end of each anode cylinder corresponds to the first air inlet, and the bottom end of each anode cylinder corresponds to the first air outlet. In practical applications, a base (not shown) is further disposed at the bottom of the housing for easy installation, and the base is a conventional base and is not the point of the present invention, so the present invention is not particularly limited.
In practical use, the first air inlet and the second air inlet are respectively used for connecting (flange-connected or welded) an external air inlet pipe (not shown in the figure), and the first air outlet and the second air outlet are respectively used for connecting (flange-connected or welded) an external air outlet pipe (not shown in the figure). In the housing, a first passage is formed between the first air inlet and the first air outlet, the gas (indicated by a dotted arrow in fig. 1) in the passage passes through each anode cylinder, the first cathode discharge in each anode cylinder ionizes the gas in the anode cylinder, and the inner wall of each anode cylinder captures the charged particles in the gas in the first passage. In the housing, a second passage is formed between the second air inlet and the second air outlet, the gas (indicated by the realized arrows in fig. 1) in the passage passes through the outside of each anode cylinder, each second cathode discharge ionizes the gas in the second passage, and the outer wall of the anode cylinder captures the charged particles in the gas in the second passage. It can be seen that the two-channel electrostatic precipitator provided by the present invention has at least the following technical advantages over the prior art: (1) compared with the prior art, the ventilation quantity of the double-channel electrostatic dust collector is doubled; (2) because the outer wall of each anode cylinder is also used for dust removal, the total surface area of the anode of the double-channel electrostatic dust collector is increased. (3) In practical application, the first air inlet and the second air inlet can be connected to the dust-containing gas from different sources through pipelines, and the function of the first air inlet and the second air inlet is equivalent to that of two electrostatic dust collectors for treating the dust-containing gas from different sources. (4) In practical application, the first cathode and the second cathode can be independently controlled to be powered on or powered off, so that the dual-channel electrostatic dust collector can selectively remove dust or not from the gas in the first channel and the gas in the second channel according to practical conditions.
Further, referring to fig. 3, in the projection of the horizontal plane, the anode cylinders 3 are distributed in a square matrix, that is: the row spacing and the column spacing of the anode cylinders are equal. Each second cathode 52 is located at the center of the square surrounded by the four adjacent anode cylinders 3. The arrangement enables the distances between each second cathode and the four adjacent anode cylinders to be equal, even if the second cathodes are installed, the uniformity of dust collection on the outer walls of the anode cylinders is improved, and the number of the second cathodes is correspondingly reduced.
Preferably, referring to fig. 3 and 7, each second cathode 52 includes a metal rod 521, each metal rod 521 is provided with four rows of barbs 522 along the vertical direction, and an included angle between any two adjacent rows of barbs on the metal rod is 90 degrees; the four rows 522 of the barbs of each second cathode point to the axes of the four adjacent anode cylinders 3 respectively. The arrangement makes the second cathode easy to manufacture, and the prickle of each row on each second cathode respectively faces the adjacent anode cylinder, thereby further improving the uniformity of dust collection on the outer wall of each anode cylinder. It should be noted that the cathode with barbs is the prior art, and the invention is not intended to propose a cathode needle with a new structure; however, the four rows of the barbs are ingeniously arranged at the center of a square formed by the four adjacent anode cylinders, and the four rows of the barbs of each second cathode point to the axes of the four adjacent anode cylinders respectively, so that the novel anode cylinder is the idea of the invention and has obvious technical benefits.
Since the anode frame is mainly used to support each anode cylinder, there are many methods for arranging the anode frames, please refer to fig. 4, the present invention provides a very simple arrangement (but not limited thereto): the anode holder 2 comprises a top plate 201 and a plurality of legs 204 (4 legs 204 are shown in fig. 4) arranged below the top; the top plate 201 is provided with through holes 2011 with the same number as the anode cylinders, and the top end of each anode cylinder 3 extends upwards from the corresponding through hole 2011 and is connected with the top plate. The top of each anode cylinder can be directly welded with the top plate, and the top of each anode cylinder can also be directly detachably connected with the top plate. The sample rack arranged in this way is simple in structure and does not interfere with the installation of the second cathode rack below. Preferably, each second cathode frame is a straight bar, each straight bar spans over the first air outlet and is detachably connected to the bottom plate of the housing, and each second cathode frame is detachably connected to the corresponding second cathode.
Referring to fig. 5, further, the first cathode frame 41 includes an outer frame 411, a plurality of connecting rods 412 are disposed on the outer frame, and each first cathode 51 is disposed on the corresponding connecting rod 412 (for convenience of viewing, the first cathode is drawn on only the rightmost connecting rod in fig. 5). It is understood that the first cathode frame is disposed on the anode frame, and an insulator (not shown) is disposed between the first cathode frame and the anode frame to achieve insulation, and the insulation is conventional in the art (see patent with publication number CN 204841950U), so the present invention is not limited thereto.
Further, an air duct 8 (preferably made of an insulating material) is arranged on the top plate 201 of the anode rack, and a flange 801 is arranged on the outer side of the bottom end of the air duct; the flange is in bolt connection with a top plate of the anode plate, and a sealing gasket is arranged between the flange and the anode plate; the top end of the air duct extends to the first air inlet. When the air duct is arranged on the anode tube, the first cathode frame is positioned in the air duct. The lateral plate of the air duct is provided with a threading pipe 803 for the power line of the first cathode frame to pass through.
In practical application, in order to uniformly distribute the air in the first channel, a second flange 802 is disposed on the inner wall of the air duct, and a wind equalizing plate (or called "airflow distributor" and not shown in the figure) is bolted to the second flange. The invention does not limit the concrete structure of the air-equalizing plate.
Preferably, each first cathode 41 is a cathode line, and each first cathode is located at the axis of the corresponding anode cylinder.
It should be understood that equivalents and modifications of the technical solution and inventive concept thereof may occur to those skilled in the art, and all such modifications and alterations should fall within the protective scope of the present invention.
