Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to plasma waste gas purification equipment. Background Art

[0002] Plasma purifiers, also known as low-temperature plasma exhaust purifiers, are based on the general electrocatalytic design concept and are divided into three independent yet integrated excitation systems: a microwave excitation zone, a plasma excitation zone, and a plate excitation zone. Each excitation zone has its own specific function, but they share similar principles. Exhaust gas is drawn into the plasma exhaust purifier by a centrifugal exhaust mechanism, passes through the treatment area, and is then discharged. Publication No. CN217568148U discloses a plasma exhaust purifier comprising a microwave excitation zone, a plasma excitation zone, and a plate excitation zone, all of which have interconnected internal cavities. The microwave, plasma, and plate excitation zones are each equipped with a mesh panel in front of them. The plasma exhaust purifier's internal cavity is equipped with multiple sets of guide plates to increase the exhaust gas flow path. The microwave excitation zone, plasma excitation zone and plate excitation zone of the utility model are all provided with mesh plates on the front side, which can effectively block the particulate matter that may exist in the exhaust gas, prevent the particulate matter from impacting the internal mechanism of the plasma exhaust gas purifier with the rapid flow of exhaust gas and causing damage to it, and play an effective protective role. The plasma exhaust gas purifier is provided with multiple groups of guide plates for increasing the exhaust gas flow path. The mesh plates create resistance to the movement of the exhaust gas, which promotes the increase of the residence time of the exhaust gas in the plasma exhaust gas purifier, thereby improving the purification effect. However, during the use of the above technology, after the exhaust gas enters the treatment equipment, the airflow distribution is often uneven. The gas flow rate is faster in some areas, and slower in other areas, or even stagnation occurs. This will not only lead to a decrease in the equipment processing efficiency, but may also cause pollutants in certain areas to fail to fully contact the purification device, affecting the exhaust gas treatment effect.

[0027] Working principle: The exhaust gas first enters the equipment through the air inlet hopper 9 and enters the air flow uniform distribution area 10. In this area, the air flow is evenly distributed through the porous plate 11 and the spoiler 16, which can ensure that the exhaust gas enters each purification area with a uniform flow rate and flow in the subsequent treatment process, avoiding local air flow turbulence or concentration, and ensuring the purification effect. After the exhaust gas enters the microwave area 19, the high-frequency microwaves generated by the microwave excitation unit 20 can excite the gas molecules and generate a large amount of plasma. The high-energy electrons and active particles in the plasma can react chemically with the pollutant molecules in the exhaust gas and decompose them into harmless or low-harm gas molecules. In the electrodeless tube area 21, the electrodeless tube group 22 generates high-intensity ultraviolet rays or other energy forms, which work synergistically with the plasma to further decompose the pollutant molecules in the exhaust gas. The role of the electrodeless tube can not only enhance the chemical reaction The efficiency can also assist in destroying the molecular structure of toxic gases and enhance the purification effect. After entering the electrode area 23, the exhaust gas is subjected to the action of the electric field, and the electrode group 24 captures the tiny particles in the exhaust gas by electrostatic adsorption. At the same time, the charged electrode can also attract pollutant molecules with opposite charges and fix them on the surface of the electrode to further purify the gas. In the microwave area 19, the electrodeless tube area 21 and the electrode area 23, the setting of the upper guide plate 27 and the lower guide plate 28 can ensure the stability and uniformity of the airflow inside the equipment. Its function is to guide the exhaust gas to flow through various functional areas, avoid turbulence or dead corners in the air flow inside the equipment, ensure that the exhaust gas fully contacts the treatment area, thereby improving the purification efficiency. After a series of treatments, the pollutants in the exhaust gas are effectively removed, and the purified gas is discharged from the equipment through the air outlet hopper 25, and finally meets the emission standards.
