The corona discharge mode in the traditional wire tube type or needle plate type purifying equipment generally concentrates on the range of a needle point for discharging, and the discharge mode causes that the generated active particles are mainly concentrated in a smaller discharge area, so that the contact area of the active particles and pollutants is limited, the mass transfer and treatment effect of the active particles is further influenced, and the purifying effect of the purifying equipment is poor. Based on this, this application has proposed a purification structure and clarification plant, and this purification structure and clarification plant can promote the purifying effect to the air.
Referring to fig. 1 to 3, an embodiment of a purification structure 10 includes a discharge assembly 100 and a low voltage electrode 200, the discharge assembly 100 includes a high voltage electrode 110 and a discharge element 120 disposed on a circumferential side wall of the high voltage electrode 110, the discharge element 120 is an internal hollow structure with two open ends, the high voltage electrode 110 is an internal hollow structure, the high voltage electrode 110 is further provided with a carrier gas inlet 1122 communicated with an interior of the high voltage electrode 110, one open end of the discharge element 120 is communicated with an interior of the high voltage electrode 110 to receive carrier gas conveyed along the carrier gas inlet 1122, and the other open end of the discharge element 120 is a corona discharge end 122; the low voltage electrode 200 is a hollow structure, the low voltage electrode 200 is provided with a gas inlet 210 for delivering gas to be purified to the inside of the low voltage electrode 200 and a gas outlet 220 for delivering the purified gas to the outside of the low voltage electrode 200, the discharge assembly 100 is inserted into the low voltage electrode 200, and the discharge element 120 is disposed in the low voltage electrode 200.
Referring to fig. 1 to fig. 3, when the purification structure 10 is in use, the carrier gas enters the high voltage electrode 110 along the carrier gas inlet 1122 and is transported to the discharge element 120, the carrier gas performs corona discharge at the corona discharge end 122 to generate active particles, and the generated active particles are dispersed inside the low voltage electrode 200 under the action of the carrier gas; the gas to be purified enters the low voltage electrode 200 along the gas inlet 210 and reacts with the active particles dispersed in the low voltage electrode 200, so as to degrade the pollutants in the gas to be purified, and the purified gas is discharged along the gas outlet 220.
Further, since the active particles generated by the discharge action of the corona discharge end 122 can be dispersed into the low-voltage electrode 200 under the blowing of the carrier gas, the contact area between the pollutants and the active particles can be increased in the same discharge space, and the mass transfer effect of the active particles is increased, thereby improving the pollutant degradation capability of the purification structure 10.
It should be noted that, in the conventional bobbin type or pin plate type purification apparatus, the voltage of the high voltage electrode 110 needs to be raised when the purification capacity is raised, but when the voltage of the high voltage electrode 110 is increased, when the voltage is increased to the air breakdown voltage, sparks are easily generated. Different with traditional line section of thick bamboo formula or faller formula clarification plant purification mode, this application blows away active particle to low voltage electrode 200 inside just can promote the purifying effect through the carrier gas, consequently, under the prerequisite that the interval between corona discharge end 122 and low voltage electrode 200 inner wall remains unchanged, can just can realize the same purifying effect with less voltage to can avoid the spark problem because of increasing the voltage brought of high voltage electrode 110.
Specifically, in use, oxygen or oxygen-containing air enters the high voltage electrode 110 along the carrier gas inlet 1122 at a flow rate of 1L/min, and the contaminant source gas enters the low voltage electrode 200 along the gas inlet 210 at a flow rate of 5L/min. In order to improve the efficiency of purifying the pollutant source gas, the gas inlet 210 and the gas outlet 220 can be communicated through a pipeline, the gas led out from the gas outlet 220 can be continuously led into the low-voltage electrode 200 along the gas inlet 210 for purification again, so that a circulating gas path is formed, and the pollutants can be treated repeatedly.
Optionally, in some embodiments, the discharge member 120 is a hollow needle. Wherein the needle tip of the hollow needle is a corona discharge end 122. Most of the corona discharge discharges air or oxygen or nitrogen passing through the tip of the needle, and then acts on pollutants, so that the energy consumption of directly discharging background gas of the pollutants is reduced. In addition, the discharge element 120 is configured as a hollow needle that both aerates and injects a free radical source and has a pointed tip to enhance the discharge effect.
Referring to fig. 2, the gas inlet 210 and the gas outlet 220 of the low voltage electrode 200 are disposed on the circumferential sidewall of the low voltage electrode 200.

It should be noted that, when the carrier gas passes through the hollow needle, the removal of the contaminants can be realized by utilizing the free radical shower of the hollow needle, the dc high voltage is applied to the high voltage electrode 110, the corona discharge occurs due to the higher electric field intensity generated by the smaller curvature radius of the tip of the hollow needle, and the carrier gas ejected from the hollow needle generates a large amount of free radicals through the corona discharge area to collide and react with the contaminants to remove the contaminants.
The carrier gas may be oxygen, oxygen-containing air or nitrogen; the carrier gas generates oxygen-containing radicals such as O ·andoh, and nitrogen-containing active substances such as NO, NO2, and NOx under the discharge action of the corona discharge end 122, and these active substances collide with the pollutant gas to be decomposed. In addition, the removal of contaminants is also partly due to the breakdown of lower-energy chemical bonds in the contaminants by direct collisions of the high-energy electrons generated by the discharge with the contaminants. In addition, oxygen or oxygen-containing air is easy to obtain, the cost is lower, and the cost is saved.
Referring to fig. 3 and 4, in some embodiments, the discharge elements 120 are multiple, at least some of the discharge elements 120 of all the discharge elements 120 extend radially outward along the radial direction of the high voltage electrode 110, and each discharge element 120 is spaced apart along the circumferential direction of the high voltage electrode 110. Thus, the discharge area of the discharge assembly 100 can be increased, and the air purification effect can be improved.
It is understood that the discharge elements 120 are radially outwardly extended along the radial direction of the high voltage electrode 110, which means that one end of the discharge element 120 is disposed on the circumferential side wall of the high voltage electrode 110, and the other end of the discharge element 120 is radially extended along the radial direction of the high voltage electrode 110.

Therefore, when the gas to be purified enters the interior of the low-voltage electrode 200 along the gas inlet 210, the gas may be fully contacted with the active particles and then discharged along the gas outlet 220, so that the contact time between the gas to be purified and the active particles is prolonged, and the purification effect is further improved.
Further, referring to fig. 1 to 3, in some embodiments, the air inlet 210 and the air outlet 220 are located on different sides of the low voltage electrode 200. Also, the contact time of the gas to be purified and the active particles can be increased, thereby further improving the purification effect.
