Embodiment 1

[0015] The dust output from the dust input port (1) and the air output from the air compressor (2) are mixed evenly in the mixing tank (3) and then enter the electrostatic precipitator through the flow regulating valve (K3). The front deflector (5) in the electrostatic precipitator box (4) makes the dust gas evenly distributed in the cross section, and the particle detector detects the dust inlet concentration at the front sampling port (6); the dust gas passes through the ionization zone (7) and The concentration at the rear of the dust collection area (8) drops sharply, and the particle detector detects the concentration at the dust outlet at the rear sampling port (9); the wind speed of the entire electrostatic precipitator is controlled by the fan (10).

[0016] By adjusting the dust content of the dust input port (1) and the air volume of the air compressor (2), the dust concentration range is 50-5000μg / m 3 , fixing other parameters (electrode spacing in the ionization zo...

Embodiment 2

[0018] This embodiment is basically the same as Embodiment 1, the special feature is that the distance between the plates in the ionization area (0.5-4cm) is changed, and other parameters (dust concentration, voltage in the ionization area, distance between plates in the dust collection area, voltage in the dust collection area and Wind speed) can get the effect of the distance between the plates in the ionization zone on the dust removal efficiency of the electrostatic precipitator.

Embodiment 3

[0020] This embodiment is basically the same as Embodiment 1. The special feature is that the output voltage (0-12kv) of the high-voltage power supply (10) in the ionization area is changed, and other parameters (dust concentration, distance between plates in the ionization area, and electrode plates in the dust collection area) are fixed. Distance, dust collection area voltage and wind speed) can get the effect of ionization area voltage on dust removal efficiency of electrostatic precipitator.

Abstract

The invention discloses a detecting device for evaluating dust collection efficiency of an electrostatic dust collector. The device comprises a gas mixing portion and an electrostatic dust collection portion; the concentration of dust output by the gas mixing portion can be adjusted through the air volume of an air compressor and the dust content of a dust input opening, and the adjustable range of the dust concentration ranges from 50 micrograms / m<3> to 5000 micrograms / m<3>; the polar plate space of an ionization zone in the electrostatic dust collection portion, the polar plate space of a dust collection zone, output voltage of an ionization zone power source and output voltage of a dust collection zone power source can be adjusted respectively, the adjustable range of the polar plate space ranges from 0.5 cm to 4 cm, and the output voltage ranges from 0kv to 12kv;and the wind speed of the whole device can be adjusted by changing the rotating speed of a fan, and the adjustable range of the wind speed ranges from 0m / s to 4m / s. the device has the obvious advantage of being capable of evaluating the influences of the dust content, the polar plate space of the ionization zone, the voltage of the ionization zone, the polar plate space of the dust collection zone, the voltage of the dust collection zone and the wind speed on the dust collection efficiency of the electrostatic dust collector.

Description

technical field [0001] The invention relates to a detection device for evaluating the dust removal efficiency of an electrostatic precipitator, in particular to a device for evaluating the dust content, the distance between plates in the ionization area, the voltage in the ionization area, the distance between the plates in the dust collection area, the voltage in the dust collection area, and the wind speed. A detection device for the influence of dust removal efficiency. Background technique [0002] With the increasingly serious industrial pollution and the increasing number of haze weather phenomena, people pay more and more attention to air quality, especially the PM2.5 index. Fine particles have small particle size, large specific surface area, are easy to carry toxic and harmful substances, and can be suspended in the air for a long time, so they have a great impact on human health and the quality of the atmospheric environment. Electrostatic precipitator technology ...
