Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic dust removal, in particular to an electrostatic dust removal device used in a coarse coal ash combustion process. Background Art

[0002] Electrostatic dust removal is a method of gas dust removal. When dust-laden gas passes through a high-voltage electrostatic field, it is electrically separated. After the dust particles combine with negative ions and carry negative charges, they tend to discharge to the anode surface and deposit. It is used to purify gas or recover useful dust particles in industries such as metallurgy and chemistry. It is a dust collection method that uses an electrostatic field to ionize gas so that dust particles are charged and adsorbed on the electrode. In a strong electric field, air molecules are ionized into positive ions and electrons. When the electrons rush to the positive electrode, they encounter dust particles, causing the dust particles to be negatively charged and adsorbed to the positive electrode and collected. During the combustion of coarse coal ash, dust is often generated, so dust removal is required.

[0003] Although the existing electrostatic precipitator is capable of performing dust removal work, there are still some problems. First, the current electrostatic precipitator is unable to reciprocate, resulting in a smaller dust removal range. Second, the multiple dust removal rods of the current electrostatic precipitator are unable to rotate, resulting in the multiple dust removal rods being unable to uniformly adsorb the dust. Therefore, an electrostatic precipitator for the coarse coal ash combustion process is needed to solve the above problems. Utility Model Content

[0019] When using the electrostatic precipitator for the crude coal ash combustion process, the device can first be moved to the specified position by rolling the moving wheel 2, and then the dust removal mechanism 7 can perform electrostatic dust removal on the crude coal ash combustion process. In order to increase the dust removal range, the reciprocating mechanism 6 is turned on, and the reciprocating mechanism 6 can drive the dust removal mechanism 7 to move up and down. The up and down reciprocating movement of the dust removal mechanism 7 can increase the dust removal range. After the dust removal is completed, the dust removal mechanism 7 is powered off, and the dust on the dust removal mechanism 7 can fall into the collection box 8 for collection, which is convenient for unified treatment of the dust.

[0020] like Figure 1As shown, as a preferred embodiment of the utility model, the reciprocating mechanism 6 includes: a sliding column 61, two ends of which are respectively fixedly connected to the top plate 5 and the bottom plate 1, and a reciprocating plate 62 is sleeved on the sliding column 61 on both sides, and the dust removal mechanism 7 is installed on the reciprocating plate 62, and a return spring 63 is fixedly connected between the reciprocating plate 62 and the top plate 5 for pushing the reciprocating plate 62 to slide downward along the sliding column 61; an upper pulling component 64, which is installed in the support box 3, and the upper pulling component 64 bypasses a pulley 65 installed on the top plate 5, and the power output end of the upper pulling component 64 is fixedly connected to the reciprocating plate 62, and is used to pull the reciprocating plate 62 to slide upward along the sliding column 61.
