Abstract
Provided is an electrostatic dust filter including a frame that is opened back and forth and forms a space through which air passes, a chemical absorbent that is accommodated in the space and absorbs harmful substance in the air, a mesh member that covers the front of the frame and has a plurality of pores through which the air passes, a ground electrode that covers the rear of the frame and has the plurality of pores through which the air passes, and is grounded, and a voltage electrode that is disposed to opposite to the ground electrode with respect to the mesh member and applied with a high voltage.
Claims8
An electrostatic dust filter, comprising:
- a frame that is opened back and forth and forms a space through which air passes;
- a chemical absorbent that is accommodated in the space and absorbs a harmful substance in the air;
- a mesh member that covers a front of the frame and has a plurality of pores through which the air passes;
- a ground electrode that covers a rear of the frame, has a plurality of pores through which the air passes, and is grounded;
- and
- a voltage electrode that is disposed opposite to the ground electrode with respect to the mesh member and is applied with a high voltage,
- wherein:
- the frame is formed in a cylindrical shape, and the space is arranged in a circumferential direction,
- the voltage electrode has a ring shape extending in the circumferential direction along a circumference of the frame,
- the ground electrode covers an inner circumferential surface of the frame, and
- the mesh member covers an outer circumferential surface of the frame.
