Haze removal device and haze removal method

Abstract

The invention discloses a haze removal device and a haze removal method. A method for electrostatic dust collection by electrified particulate matters is not adopted, an electrostatic attraction method is adopted, a bipolar plate structure is not adopted, an electrode plate group is adopted, a distance between the electrode plates is short, low tension can be adopted and the safety is good; stage purification is adopted, and oversized particulate matters can be prevented from being adsorbed onto the electrode plate, thus, the whole purification effect is not influenced and the whole purification effect is better; particularly, a groove structure is adopted, on one hand, the electric field is reconstructed, on the other hand, gas can roll and form turbulent flows between the electrode plates, the particulate matters can be adsorbed favorably; more particulate matters can be contained by the groove structure, and the maintenance period is prolonged.

Description

technical field [0001] The invention relates to a haze removal device and method. Background technique [0002] With the development and progress of production, the pollution caused by production has gradually increased, and environmental problems have gradually become serious and began to affect human health, which has gradually become the focus of people's attention. Smog is one of the environmental problems that have attracted much attention in recent years. Smog is the result of the interaction between specific climatic conditions and human activities. The economic and social activities of a high-density population will inevitably emit a large amount of fine particulate matter (PM 2.5). Once the emission exceeds the atmospheric circulation capacity and carrying capacity, the concentration of fine particulate matter will continue to accumulate. range of smog. "Haze" in the present invention refers to fine particles that cause haze. [0003] There are many ways to remo...

Problems solved by technology

However, for example, water mist purification requires sufficient water sources for support, so it needs to occupy certain public resources, and the subsequent treatment of sewage is relatively difficult

[0006] Document CN103727500A is further based on street light poles, using solar panels or self-configured municipal power supply to drive the light poles, and purifying the air through fan induction and filter removal. The principle is very simple, and it is not possible to classify the air. The effect is not good, it is easy to cause the clogging of the filter and affect the purification effect

[0007] Chinese patent document CN103769299A discloses a method of firstly charging the particles through a corona electrode, and then carrying out adsorption of charged particles through an electrode plate for purification. In some applications, charged particles can also be generated by ionizing the air. This method It is not suitable for low-voltage electricity, and the safety of use is relatively poor

[0008] In addition, the current electrode plates generally use electrode plates with flat surfaces to generate a uniform electric field. The dust holding capacity on the surface is very small, and the cleaning frequency is relatively high. Relatively large, in order to maintain a considerable electric field strength requires a relatively large voltage between the plates

For this reason, in some applications, for example, a spiral electrode plate configuration is used to extend the length of the electrode plate, so as to improve the overall dust holding capacity and electrostatic dust removal effect, but the overall effect is still not good
