Description

A modular high-voltage electrostatic equipment for die-casting exhaust gas purification machine

Technical Field

The utility model belongs to the technical field of die-casting exhaust purification technique and specifically relates to a module formula high-voltage electrostatic equipment for die-casting exhaust gas purification machine.

In the process of die casting production, the release agent can volatilize at high temperature to generate smoke, heat, water vapor, dust, carbon dioxide and the like, thereby polluting the environment. The release agent mainly comprises the following components: 70 percent of water, and 30 percent of polysiloxane emulsion, water emulsifier and the like. According to experience, high-voltage electrostatic waste gas treatment equipment is generally recommended to eliminate oil mist and peculiar smell from the source by combining the characteristics of the flue gas. The high-voltage electrostatic waste gas treatment equipment is arranged on the upper part of a die-casting machine die-opening frame, gas containing oil mist enters a pre-filtering area from an air inlet under the action of an internal negative pressure area, large-particle solid and liquid are intercepted and separated, and air containing fine oil mist and dust flows out of the pre-filtering area and then enters a high-voltage charged area. High voltage direct current (11-15 KV) is applied between a cathode and an earthed anode plate to form an uneven electric field, gas is ionized due to cathode discharge to form ions and electrons, solid or liquid particles in the electric field are charged due to continuous bombardment of gaseous ions, so that the charged particles fly to opposite polarities under the action of electric field force (coulomb force), the anode is usually used as a dust collecting electrode, and the charges carried by the particles are neutralized, separated, trapped and partially carbonized at the dust collecting electrode. Meanwhile, the high-voltage electrostatic electric field effectively degrades harmful components, an effective purification effect is achieved, and finally, clean air is directly discharged into the air under the pushing of the airflow through the filter screen grating. After the electrode works for a certain time, the carbonized microparticles are adsorbed on the surface of the polar plate (made of aviation aluminum plates), when the microparticles are adsorbed to a certain thickness, the treatment effect can be reduced, the air suction resistance can be increased, and at this time, an automatic cleaning signal can appear to require cleaning of the electrode. When the existing high-voltage electrostatic waste gas treatment equipment is used for cleaning the electrode, the equipment needs to be stopped and the electrode needs to be detached for cleaning, so that the work is delayed and the process is troublesome.
