Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors for coal conveying systems, in particular to a wet dust collector for coal conveying systems. Background Art

[0002] The existing electrostatic precipitator equipment of the coal transportation system is a dry dust collector, which is installed and arranged at each transfer station. Its structure consists of inlet and outlet bellows, positive and negative electric field systems, ash hoppers, ash discharge valves and electrical control systems. It is a dust removal device that uses a strong electric field to ionize the gas, that is, to generate corona discharge, and then charge the dust, and under the action of the electric field force, separates the dust from the gas. This type of electrostatic precipitator is suitable for coals with low dust concentration and small volatility.

[0003] The separation of suspended dust particles in gas by electrostatic precipitator mainly includes the following complex and interrelated physical processes: applying high voltage to generate strong electric field, ionizing gas and generating corona discharge; charging of suspended dust particles; charged dust particles moving toward the electrode under the action of electric field force; charged dust particles being captured in the electric field; vibrating and cleaning. In the uneven electric field composed of the corona electrode and the dust collecting electrode, the discharge electrode is the cathode, the dust collecting electrode is the anode, and a high-voltage DC power supply is applied. When the intensity of this electric field is increased to the corona value, a negative corona is formed around the corona electrode, the ionization of gas molecules is enhanced, and electron collapse occurs continuously, generating a large number of positive and negative ions. The positive and negative ions are neutralized by the corona electrode. Negative ions and free ions are transferred to the dust collecting electrode. When the gas carrying dust passes through, these negatively charged particles will continuously encounter and be adsorbed on the dust particles during movement, so that the dust is charged. Under the action of the electric field force, it quickly moves to the dust collecting electrode (anode plate), releases negative charges, and deposits itself on the dust collecting plate. By vibrating the cathode and anode, the dust deposited on the anode plate falls into the ash hopper for discharge.

[0004] At present, this type of electrostatic precipitator has serious dust accumulation inside the pipeline during use, and coal powder in the pipeline is prone to spontaneous combustion. Utility Model Content
