Electric field structure for improving cooking fume purification efficiency

Abstract

The invention discloses an electric field structure for improving oil fume purification efficiency, which includes a composite electric field, the composite electric field includes a plurality of rows of cylindrical smoke removal channel groups arranged in sequence from top to bottom, and the cylindrical smoke removal channel groups include horizontally arranged A plurality of cylindrical anode cylinders, gaps are formed between the adjacent four cylindrical anode cylinders in the upper and lower adjacent rows of cylindrical smoke removal channel groups, and square anodes parallel to the cylindrical anode cylinders are arranged in the gaps The four sides of the square anode cylinder are respectively tangent to the sides of the cylindrical anode cylinder. Both the cylindrical anode cylinder and the square anode cylinder are equipped with cathode needles, and the cathode needles are located between the cylindrical anode cylinder and the square anode cylinder. axis. The electric field structure of the present invention can greatly increase the anode area for absorbing oil fume through the anode cylinder with a special composite structure, and at the same time, it will not increase the electric field structure, utilize the space reasonably and efficiently, and greatly improve the oil fume adsorption efficiency.

Description

technical field [0001] The invention relates to an electric field structure, in particular to an electric field structure for improving oil fume purification efficiency. Background technique [0002] At present, with the enhancement of people's awareness of environmental protection, air purifiers will be installed in places with large oil fume emissions such as factories and catering industries to reduce oil fume emissions. The electrostatic oil fume removal device can effectively remove the oil fume in the exhaust gas by using the action of the electric field, so that the exhaust gas can meet the emission standard. The traditional electrostatic oil fume removal device has a built-in honeycomb electric field structure. The honeycomb electric field structure is composed of a plurality of oil fume removal channels, and a cathode needle is installed in each oil fume removal channel. When working, the oil fume removal channel is grounded, and the cathode pin is connected to a n...

Problems solved by technology

[0003] However, although the electric field of the traditional honeycomb structure can effectively purify the oil fume, its structure itself will cause a small contact area with the flue gas, that is, in the same space, the area of ​​the anode plate that can be installed to absorb the oil fume is small , thus affecting the removal effect of oil fume
