Description

Technical Field

[0001] The utility model relates to the field of gas filtration, in particular to an electrostatic neutralization application device. Background Art

[0002] In gas filtration experiments, aerosol particles usually carry charges. These charges may cause the particles to suspend in the air and attract and repel each other, thus affecting their stability and the filtration efficiency of the filtration experiment. Therefore, an electrostatic neutralizer is usually installed to neutralize the static electricity in the aerosol. However, in ordinary applications, the electrostatic neutralizer is directly added to the pipeline, resulting in a great reduction in the neutralization effect of the electrostatic neutralizer. At the same time, the aerosol generated by the aerosol generator contains a large amount of water molecules, which causes great interference to the gas filtration experiment, seriously affects the filtration efficiency, and leads to inaccurate data. Content of the Utility Model

The electrostatic neutralizer generates ions or electrons opposite to the charges of the aerosol particles to neutralize their charges with the aerosol particle charges, thereby eliminating the electrostatic effect. The device is connected with the neutralization chamber at the outlet of the electrostatic neutralizer, and at the same time, the neutralization chamber is connected with the aerosol generator. In the neutralization chamber, the generated aerosol is neutralized, thereby achieving the purpose of electrostatic neutralization.

[0017] The following will further illustrate the utility model in combination with the drawings and relevant knowledge, and describe it clearly and completely. Obviously, the described applications are only a part of the embodiments of the utility model, rather than all embodiments.

[0018] Refer to Figure 1 - Figure 2As shown in the figure, an electrostatic neutralization application device of the present utility model includes a neutralization chamber 1, a neutralizer 2 and an aerosol generator 3. On the upper side of one end of the neutralization chamber 1, there is a neutralizer injection port 4, and on the lower side, there is a neutralization chamber inlet 5. The neutralizer injection port 4 is connected to the neutralizer 2, and the neutralization chamber inlet 5 is connected to the aerosol generator 3. At the upper end inside the neutralization chamber 1, there is a first neutralization baffle 6, which is arranged opposite to the neutralizer injection port 4, and at the lower end inside, there is a distribution and water filtering baffle 7, which is arranged opposite to the neutralization chamber inlet 5. In the present utility model, when the aerosol is flowing at a high speed, it will impact the distribution and water filtering baffle 7. After the impact, the large water molecules will remain on the distribution and water filtering baffle 7, and the water on the distribution and water filtering baffle 7 will flow down along the distribution and water filtering baffle 7 under the action of gravity and be discharged through the drain port; and by setting the first neutralization baffle 6 to block the ions generated by the neutralizer, the ions will neutralize the charges of the aerosol blocked by the distribution and water filtering baffle 7, thereby eliminating the electrostatic effect.

[0019] The electrostatic neutralizer of the present utility model generates ions or electrons with opposite charges to the aerosol particles to neutralize their charges with the aerosol particles, thereby eliminating the electrostatic effect. To achieve this effect, the device is connected between the outlet of the electrostatic neutralizer and the neutralization chamber, and at the same time, the neutralization chamber is connected to the aerosol generator. Inside the neutralization chamber, the aerosol will be neutralized, thereby achieving the purpose of electrostatic neutralization. A water separation device is integrated in the neutralization chamber to filter the moisture in the aerosol.

[0020] In the present utility model, the bottom plate of the distribution and water filtering baffle 7 is provided with a number of leakage holes 8 for the water to flow down to the drain port.

[0021] As a further scheme of the present utility model, an aerosol injection port 9 is provided at the other end of the neutralization chamber, and the neutralized aerosol is used for subsequent gas filtration experiments through the aerosol injection port.

[0022] As a further scheme of the present utility model, a water molecule filter 10 is provided near the aerosol injection port inside the neutralization chamber. Further, the water molecule filters are respectively provided at the upper and lower ends inside the neutralization chamber. More preferably, the water molecule filter is a desiccant, which absorbs the remaining moisture in the gas inside the cavity to keep the neutralized gas dry. More preferably, the desiccant used is silica gel desiccant, which has a good drying effect and does not affect the aerosol.

[0023] As a further solution of the present utility model, a drain ball valve 11 is provided at the lower end of the neutralization chamber. Further preferably, a ball valve 12 is respectively provided between the neutralization chamber and the neutralizer and the aerosol generator. After the gas is generated by the aerosol generator 3, it enters the neutralization chamber inlet 5 through the ball valve 12. In order to ensure the neutralization effect of the neutralizer 2, the cavity of the neutralizer 2 is made of ceramic material. The neutralizer 2 is injected from the electrostatic neutralizer injection port 4 and mixed with the aerosol to neutralize the static charges in the aerosol. After the gas enters the neutralization chamber, it collides with the internal baffle to filter out some large water molecules and then is automatically discharged through the drain ball valve 11. When the gas passes through the cavity outlet, there are many fine holes distributed above the outlet. There is a desiccant on the fine holes to absorb the remaining moisture in the aerosol gas to ensure that the gas in the aerosol injection port is dry.

[0024] In the present utility model, a second neutralization baffle 13 is provided at the upper end inside the neutralization chamber. The side baffle distributing the water filtering baffle is located between the first neutralization baffle 6 and the second neutralization baffle 13. Refer to Figure 1 As shown, by increasing the neutralization time, the charge of the aerosol can be fully neutralized.

[0025] In the present utility model, the aerosol entering from the neutralization chamber inlet is electrostatically neutralized with the gas injected from the electrostatic neutralizer injection port in the chamber. By generating ions or electrons with opposite charges to the aerosol particles, they are neutralized with the aerosol particle charges, thereby eliminating static electricity and going out from the aerosol outlet to the aerosol injection port to complete the injection.
