[0005] Advantages and disadvantages of the honeycomb electric field of the prior art: 1, cylindrical honeycomb electric field ( figure 1 ) CN205236186U honeycomb electric field, the advantage of this technology is that the cathode discharge needle is located in the center of the cylinder, the distance from the discharge needle to the cylinder wall is equal, the discharge intensity is uniform, and it has extremely high purification and adsorption capabilities, but the problem comes, multiple When the cylinders are combined, there will be a gap between the cylinders. The technical term is called the blind area, which is the part that blocks the airflow. Due to the existence of the blind area, these parts will block the airflow. It is not just as simple as blocking, When the airflow is blocked, it will bounce back, and the rebounded airflow will interfere with the forward airflow and form turbulence. We know that the existence of turbulence will make the airflow in the entire equipment unstable. Due to the instability of the airflow, it will cause the purifier The processing efficiency is unstable. Just imagine that a device with unstable processing efficiency is a substandard product, so this problem has been plaguing the industry. Secondly, due to the existence of blind spots, the resistance is increased and the drag coefficient of the whole machine is increased. On the same cross-section The volume of gas passing through will be reduced

2. The hexagonal tube combined honeycomb electric field, its advantage is that the hexagonal tubes can be seamlessly combined, there is no blind area, and the wind resistance is extremely low. This is the biggest advantage of the hexagonal tube honeycomb electric field, but its fatal The disadvantage is that the distance from each point to the center of the hexagonal tube is not the same, that is to say, the distances from the six sides and six corners to the center are not the same, so the cathode discharge needle set at the center of the tube will be different from the center. The surrounding distance is not equal and the discharge intensity is inconsistent. Under the voltage of more than 20,000 volts, the difference of a few millimeters is the difference of several thousand volts, which will lead to uneven discharge, indicating that the exhaust gas components in the airflow flowing through the hexagonal tube are absorbed. It is inconsistent with the decomposition effect. The electric fields of the six corners farther from the center are weaker, and the processing efficiency is poor, which leads to a decrease in the purification efficiency of the entire set of equipment. This is also a difficult problem that the industry cannot solve at present.
