Problems solved by technology

[0003] The currently used electrostatic precipitator mainly makes free electrons attach to the dust particles by breaking down the air discharge, but there are several problems in using this method: first, ozone is bound to be generated in the process of breaking down the air, Secondary pollution to the environment; the second is to use the method of breaking down the air. The discharge capacity is large enough to ensure that enough dust particles can be charged. If the power is small, some dust particles cannot be charged, but the greater the discharge capacity, The greater the amount of ozone in the air, the more serious the secondary pollution will be; the third is that it is difficult for the dust removal device to completely absorb the generated charge, and the unabsorbed charge leaves the dust removal device with the fresh air, making the fresh air charged, which is different from the neutral air. The normal air is potentially dangerous; the fourth is that the entire device needs to be continuously discharged during use, which makes the overall energy consumption of the device higher
Although this device can realize the rapid cleaning of dust, the dust collection still uses the method of breaking down the air to make the dust particles stick to free electrons.

Abstract

The invention discloses an electrostatic dust collection device based on a non-uniform electric field, which includes a dust collection electrode, a shielding pipe and a fan. The shielding pipe is coaxially sleeved on the outside of the dust collection electrode through an electrode support assembly, and the dust collection electrode is connected to a high-voltage power supply. An electrode dust-collecting channel through which dust-containing gas passes is formed between the shielding tube and the dust-collecting electrode. Both ends of the electrode dust-collecting channel are open. One end of the electrode dust-collecting channel is an air inlet, and the other end is an air outlet. There is a fan on the outside that brings the dust-laden gas into the dust-collecting channel of the electrode; the dust-collecting electrode, the shielding tube and the support assembly form the electrostatic dust-collecting unit in the electrostatic dust-collecting device, and the electrostatic dust-collecting units are arranged in parallel; The shielding tube is a multi-tube shape arranged in concentric circles, and is arranged in increasing order from the dust collecting electrode radially outward. The invention can realize gas dust collection under the premise of not breaking through the air, has simple device structure, low energy consumption, does not generate ozone, and avoids secondary pollution.
