Description

Technical Field

[0001] The present invention relates to the field of environmental protection, including flue gas purification, chemical reactions and the like. Background Art

[0002] With the rapid development of industry, there are many occasions, such as environmental protection, where pollutants in the gas need to be treated, and the existing technology is not efficient. Summary of the invention

[0003] In view of the defects in the prior art, the present invention provides a highly efficient gas-liquid direct contact spray purification device.

[0004] A spray purification device, characterized in that it includes: a peripheral flue, a spray head, and a baffle; wherein the peripheral flue includes an inlet end and an outlet end; the spray head is installed inside the peripheral flue; flue gas enters the peripheral flue from the inlet end, passes through the spray head and the baffle, and leaves the flue from the outlet end.

[0005] The spray purification device is characterized in that the spray head sprays toward the baffle and sprays a large number of droplets or liquid columns.

[0006] The spray purification device is characterized in that the droplets or liquid columns sprayed from the spray head reach the baffle surface and rebound and break. These rebounded and broken tiny droplets can be better mixed with the flue gas, thereby greatly improving the purification efficiency.

[0007] The spray purification device is characterized in that the distance between the spray head and the baffle is between 0.3 and 1.5 meters, which is suitable for the spray head droplets to reach the baffle surface and bounce back.

[0008] The spray purification device is characterized in that there is a power supply device between the spray head and the baffle, so that there is a certain voltage between the spray head and the baffle. The voltage can be a direct current or a high-frequency alternating current voltage. The voltage can make the droplets rebound and break more fully on the baffle, thereby improving the purification efficiency. The voltage also charges the droplets. The voltage can also make the dust in the flue gas more easily reach the baffle surface and collide with the droplets.

[0009] The spray purification device is characterized in that the baffle is covered with a spike-shaped surface facing the spray head, which can optimize the rebound and breakage of droplets.

[0010] The spray purification device is characterized in that the baffle plate vibrates in a direction perpendicular to the plate surface, and the vibration can optimize the rebound and breakage of the droplets.

[0011] The spray purification device is characterized in that the baffle surface is a hydrophobic surface, thereby optimizing the rebound and breakage of droplets.

[0012] The spray purification device is characterized in that the spray head sprays alkaline or neutral liquid. BRIEF DESCRIPTION OF THE DRAWINGS
