Electrostatic dust collection device for chimneys

Abstract

An electrostatic dust collection device for a chimney, installed inside the chimney, includes a conductive component, a plurality of discharge tips, and a water curtain device. The conductive component is arranged in a ring shape inside the chimney. The discharge tips are arranged circumferentially along the conductive component and facing it, causing point discharge between the discharge tips and the conductive component to generate ions. This charges the dust particles rising with the flue gas, causing them to adhere to the conductive component due to electrostatic attraction. The water curtain device is located above or near the conductive component to generate a water flow that washes away and removes the dust adhering to the conductive component. In one embodiment, the water curtain device is connected to a filter tank and a water collection tank, allowing the filtered water to be recycled and reused. This structural configuration enables dust collection within the chimney.

Claims

1. An electrostatic dust collection device for a chimney, comprising: a conductive member disposed within the chimney and arranged in a ring; a plurality of discharge tips disposed within the chimney and arranged circumferentially along the conductive member, wherein the discharge tips face the conductive member; wherein, The discharge tips form a tip discharge with the conductive member to generate ions, which charge the dust particles rising with the flue gas and cause them to adhere to the conductive member due to electrostatic action; and a water curtain device is disposed above or near the conductive member to generate water flow to wash away and remove the dust adhering to the conductive member.

2. The electrostatic dust collection device for the chimney as described in claim 1, wherein, The water curtain device is connected to a filter tank and a water collection tank. After being flushed by the water curtain device, the water flows through the filter tank and then into the water collection tank. A water pump returns the water in the water collection tank to the water curtain device for recycling.

3. The electrostatic dust collection device for the chimney as described in claim 1, wherein, The discharge tips and the water curtain device are electrically connected to a controller to control the operation of the tip discharge and the water flow.

4. The electrostatic dust collection device for the chimney as described in claim 1, wherein, These discharge tips are densely distributed along the entire circumference of the conductive member, so that the flue gas must pass through an ion interaction zone during its ascent.

5. The electrostatic dust collection device for the chimney as described in claim 1, wherein, The conductive component is a metal mesh, metal grid, or conductive plate with through holes.

6. The electrostatic dust collection device for the chimney as described in claim 1, wherein, The action of generating ions at the discharge tip and the action of generating water flow in the water curtain device are performed synchronously.

7. The electrostatic dust collection device for the chimney as described in claim 1, wherein, The chimney is installed in an industrial exhaust system and connected to a device that generates exhaust gas, so that the exhaust gas is treated by dust collection in the ion action zone before being emitted.
