Description

Technical Field

[0001] The utility model relates to the technical field of waste gas desulfurization, in particular to a high-efficiency spray tower for waste gas desulfurization. Background Art

[0002] The spray tower, also known as the scrubber or water scrubber, is a gas-liquid generating device. The waste gas is fully in contact with the liquid, and its solubility in water or chemical reaction is used to reduce its concentration by adding drugs, so as to become clean gas that meets national emission standards. It is mainly used to treat inorganic waste gas, such as sulfuric acid mist, hydrogen chloride gas, nitrogen oxide gas of different valence states, namely NOX, dust waste gas, etc.

[0003] According to a Chinese patent application with patent number 202223437287.3, a high-efficiency spray tower for industrial waste gas treatment is disclosed, including a spray tower body, the outer wall of the lower end of the spray tower body is connected to a waste gas inlet, the top of the spray tower body is connected to an outlet, and a spray device, a steam-water separator and a demisting device are arranged inside the spray tower body; the spray device includes a spray pipe and an equipment pipe that supplies spray liquid to the spray pipe and is connected to the spray pipe, and the lower surface of the spray pipe is connected to a plurality of spray heads that are arranged obliquely and form cross-sprays with each other; the steam-water separator is an abalone Ball ring filler, at least three of which are provided, and the at least three ball ring fillers are located in the middle and upper part of the spray tower body, and are arranged in sequence from bottom to top; the demisting device is located above the steam-water separator, and the demisting device includes a tube packing for cooling the mist and a demisting layer located above the tube packing and demisting the cooled mist. The porous ceramic plate nano demister replaces the traditional large-volume demister, which not only has a better demisting effect, but also makes the demister miniaturized and lightweight, which is conducive to the miniaturization and lightweight of the high-efficiency spray tower. The waste gas enters the spray tower body through the waste gas inlet, and the pollutants in the waste gas can be effectively adsorbed by the ball ring filler.

[0004] When the high-efficiency spray tower for industrial waste gas treatment is in use, the waste gas is directly introduced into the interior of the spray tower through the fan. However, the waste gas generally contains more solid particle impurities. After long-term use, the fan and the inside of the input pipe will be contaminated with a large amount of solid impurities, affecting the air intake. At the same time, it is not convenient to clean, which reduces the practicality of the high-efficiency spray tower for industrial waste gas treatment. For this reason, we propose a high-efficiency spray tower for waste gas desulfurization. Utility Model Content
