Technical Field

The invention belongs to the technical field of chemical equipment, and particularly relates to a cleaning system and a cleaning method for polar plates of an electric dust collector.

Background

The electric dust collector is a dust removing device for separating dust particles in gas by using electric power, has the advantages of high dust removing efficiency, good temperature resistance, large smoke gas treatment amount, low system resistance and the like, is widely applied to the industries of thermal power, metallurgy and chemical industry, and is used for recovering valuable elements and reducing dust content in smoke gas. In a non-uniform electric field formed by the dust-containing gas passing through a high-voltage direct-current power supply, the negative electrode of the power supply is called as a cathode, a discharge electrode and a corona electrode, the positive electrode of the power supply is called as an anode, a collector and a precipitation electrode, and the electric field intensity near the cathode forces the gas to collide and ionize to form a large amount of positive and negative ions. Most of dust collides with negative ions to be charged negatively and flies to a dust collecting electrode, only a very small amount of dust is accumulated on the corona electrode, the dust collecting electrode and the corona electrode are periodically shaken, and the dust adsorbed by the two electrodes falls into a dust collecting hopper. After the electric dust collector operates for a period of time, dust adhesion can occur on the electrode wires and the polar plates, after the electrode wires of the electric dust collector are adhered, the discharge tips on the electrode wires are shielded, dust-containing smoke passes through the electric dust collector, dust cannot be effectively charged, and the dust collection efficiency of the electric dust collector is reduced. At present, the polar plates and the polar plates of the electric dust collector are generally treated by three modes of water washing, sand blasting, polar plate replacement.

After the electric dust collector operates for a period of time, dust adhesion can occur on the electrode wires and the polar plates, after the electrode wires of the electric dust collector are adhered, the discharge tips on the electrode wires are shielded, dust-containing smoke passes through the electric dust collector, dust cannot be effectively charged, and the dust collection efficiency of the electric dust collector is reduced. At present, the bonding of polar lines and polar plates of an electric dust collector is generally processed by the following 3 modes:

1. water washing: the cleaned sewage is difficult to collect by adopting water washing, a plurality of harmful elements and heavy metals are used in the dust, the generated sewage is required to be treated completely, and the flue gas is required to be introduced into the electric dust collector as soon as possible after the water washing to bake the moisture in the electric dust collector, so that the corrosion to the interior of the electric dust collector is generated. And in the cleaning process, personnel must enter the electric dust collector, so that the working environment is poor.

2. Sand blasting treatment: the iron sand is sprayed out from a spray gun by using compressed air through sand blasting treatment and special equipment, and the iron sand impacts the bonding materials on the polar plate and the polar line of the electric dust collector. The sand blasting treatment is used, so that the discharge tip on the electrode wire is difficult to avoid being damaged, an operator needs to enter the internal operation of the electric dust collector, a large amount of dust is generated during operation, and the smoke dust contacts the skin of the operator to cause the skin allergy and other symptoms of the operator.

3. Polar line and polar plate replacement: the maintenance time required for replacing polar plates is long, and the maintenance cost is high. Personnel need get into the inside operation that carries out of electrostatic precipitator among the operation process, also can produce the smoke and dust and fly upward when polar line, polar plate demolish, can't avoid the condition such as operation personnel allergy to take place. And the detached old polar lines and polar plates can be treated only after being cleaned, so that a large amount of sewage and waste steel are generated.
