Description

Technical Field

[0001] The utility model relates to the technical field of anti-corrosion construction of desulfurization towers in power plants, in particular to a spraying device used for anti-corrosion construction of desulfurization towers in power plants. Background Art

[0002] A power plant desulfurization tower is a device used to reduce sulfur dioxide (SO2) emissions from coal-fired power plants and other industrial processes. Its primary function is to absorb SO2 from flue gas through an absorbent, thereby reducing the SO2 content in the flue gas and ultimately reducing air pollution. To prevent corrosion, power plant desulfurization towers are typically coated with an anti-corrosion agent during construction.

[0003] According to a Chinese patent, a spraying device for anti-corrosion construction of desulfurization towers in power plants, with the announcement number CN216605784U, includes a device body, a base and a pulley. Two sets of connecting parts are fixed on both sides of the base, and the bottoms of the two sets of connecting parts are fixedly connected to the limiting parts together. The vertical end of the base is provided with a driving part. In the utility model, when using the sprayer, the threaded rod is rotated to move it downward. When the block at the bottom of the threaded rod abuts against the cylindrical groove of the connecting plate, the threaded rod is continued to be rotated, which drives the limiting part downward, causing the two L-shaped rods to move down between the two pulleys, locking the two together, and preventing the pulley from moving when the sprayer is working, reducing unnecessary things from happening. When the threaded rod is rotated in the opposite direction, the block slowly separates from the limiting part, and then it is reset by the stretched elastic part to drive the limiting part upward, so that the sprayer can move. This structure enhances the use effect of the sprayer.

[0004] In this device, a pulley drives the base to move, allowing the main body of the device to spray the desulfurization tower of a power plant. However, the existing device still has the following problems: when spraying at different heights of the power plant desulfurization tower, the main body of the device needs to be held by the liquid outlet pipe, resulting in uneven spraying of the power plant desulfurization tower and causing differences in the anti-corrosion effect of the power plant desulfurization tower. Therefore, a spraying device for anti-corrosion construction of power plant desulfurization towers is proposed. Utility Model Content
