Electron dam air purifier

Abstract

The invention discloses an electron dam air purifier comprising an electrode chamber, and dust lock electrodes and tube pin electrodes arranged in the electrode chamber; the pin electrodes and the dust lock electrodes are arranged according to the ratio: N: N+1, wherein the N is >=1; the dust lock electrodes and the tube pin electrodes are arranged at intervals along a gas inlet direction, and respectively connected with a high voltage power source; the adjacent dust lock electrode and tube pin electrode form an electrode pair; the air is purified in the electrode chamber so as to obtain purified air. Airflow penetrates the electrode pair in a positive-negative electrode direction instead of a conventional direction vertical to the positive-negative electric field direction, so current consumption is small, strong electric field is not needed, and ozone can hardly be generated, so power supply rate can be greatly reduced; the air passes the dust lock electrode and tube pin electrode in a laminar flow mode, so wind resistance is small; the electron dam air purifier can effectively kill bacteria and virus in the air, is good in air cleaning effect, strong in safety, low in product energy consumption, high in efficiency, and energy saving.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to an air purification device. Background technique [0002] Existing air purification devices mainly include electrostatic precipitators and high-efficiency filters. The working principle of the electrostatic precipitator is to use a high-voltage electric field to ionize the airflow to be treated. The airflow flows through the electric field perpendicular to the direction of the electric field, and the dust charges in the airflow are separated from the airflow under the action of the electric field. In order to achieve an ideal dust removal rate, the operating voltage of the electrostatic precipitator needs to be maintained at 40-75kV or even above 100kV, and the current is relatively large. When the specific resistance of the dust in the electrostatic precipitator is large, the voltage gradient formed between the dust layers will produce local Breakdown and d...

Problems solved by technology

In order to achieve an ideal dust removal rate, the operating voltage of the electrostatic precipitator needs to be maintained at 40-75kV or even above 100kV, and the current is relatively large. When the specific resistance of the dust in the electrostatic precipitator is large, the voltage gradient formed between the dust layers will produce local Breakdown and discharge phenomena, resulting in a decrease in dust removal efficiency and a large amount of ozone

At the same time, since the electrostatic precipitator cannot lock the dirt by itself, the previously adsorbed dirt will be blown out again when the power is turned off or restarted, re-polluting the air

[0003] When the high-efficiency filter is in use, the filter screen will be blocked by dirt in a short period of time and will fail. It has no bactericidal effect and cannot filter out dirt with too small particles, and the air pressure difference through the filter screen is very large. Excessive consumption
