Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.
Fig. 1 is a schematic perspective view of a dust collecting net structure of an electrostatic precipitator, wherein A, B denotes a dust collecting net, A, B denotes two sections of the dust collecting net, and a and B are spliced to form the dust collecting net. The two ends of the dust collecting net, namely C and D, are referred to as air homogenizing cylinders, and the air homogenizing cylinders are used for air inlet and air outlet (radial air inlet and radial air outlet, and air flow axially passes through the inside of the dust collecting net) more uniformly. The mesh holes arranged on the air homogenizing cylinder are larger.
Fig. 3 is a cross-sectional view E-E of fig. 1, and fig. 2 is an enlarged view F of fig. 1, in conjunction with fig. 3. The dust collecting net comprises an outer supporting cylinder 1 and an inner supporting cylinder 2, the inner supporting cylinder 2 is sleeved inside the outer supporting cylinder 1, and the outer supporting cylinder 1 and the inner supporting cylinder 2 are connected through a connecting piece 3. In this example, the connecting piece 3 is ring-shaped, the outer edge of the connecting piece 3 (connecting ring) is connected with the end edge of the outer supporting cylinder 1 in a matching way, and the inner edge of the connecting piece 3 (connecting ring) is connected with the end edge of the inner supporting cylinder 2 in a matching way. Six bar-shaped lightening holes 31 are further formed in the connecting piece 3 (connecting ring) for lightening the weight, the lightening holes 31 serve to lighten the weight of the connecting piece 3, and the number and the shape of the lightening holes 31 are not particularly limited. The lightening holes 31 have another function of improving the circulation efficiency of the airflow.
In this example, the outer support tube 1 and the inner support tube 2 are respectively provided with two sections, which is convenient for installation and modular manufacture and also convenient for customizing different length specifications. In this case, the connection pieces 3 are connected between the ends of the outer support tube 1 and the corresponding ends of the inner support tube 2, thereby facilitating manufacture; the connecting member 3 may be disposed at the end portions of the outer support tube 1 and the inner support tube 2, for example, at the middle portion of the outer support tube 1 and the inner support tube 2 in the length direction.
In this case, the connecting members 3 are provided at the ends of the outer support cylinder 1 (also at the corresponding ends of the inner support cylinder 2), and the connecting members 3 are provided at both ends of the outer support cylinder 1, thereby making it more stable between the outer support cylinder 1 and the inner support cylinder 2. Of course, in other embodiments, the connecting member 3 may be provided at only one end portion of the outer support cylinder 1 (and a corresponding one end portion of the inner support cylinder 2).
Fig. 4 corresponds to fig. 3, showing the relationship between the outer support tube 1, the inner support tube 2 and the steel mesh 4, as in fig. 4. As shown in fig. 4, the steel mesh 4 is wound around the periphery of the inner support tube 2, and the steel mesh 4 substantially fills the space between the outer support tube 1 and the inner support tube 2, so that the winding manner is favorable for forming the steel mesh 4 with different radial thicknesses, and the steel mesh 4 is convenient to disassemble during later maintenance (cleaning or replacement). The main function of the steel mesh 4 is to adsorb charged particles. As shown in fig. 4, after the electrode rod is disposed in the inner support tube 2, high voltage is applied to the electrode rod, and the inner space of the inner support tube 2 discharges, so that the particles in the air flow flowing axially through the inner support tube 2 are charged, and the charged particles are adsorbed in the steel mesh 4. Therefore, the steel net 4 is mainly used for adsorbing the particulate matter. In the later maintenance, the steel mesh 4 needs to be cleaned or replaced.
