Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, specifically to a desulfurization tower spray layer anti-clogging rotary nozzle device. Background Technology

[0002] Power plants generate large amounts of sulfur-containing waste gas during operation. If this waste gas is directly released into the atmosphere, it will cause serious environmental pollution. Therefore, desulfurization treatment is necessary. Desulfurization towers are one of the commonly used desulfurization devices. The spray layer is a key component of the desulfurization tower. Its function is to evenly spray the desulfurizing agent inside the tower, ensuring full contact with the sulfur-containing waste gas to achieve the purpose of desulfurization.

[0003] A utility model patent with publication number CN207324489U discloses an anti-clogging desulfurization tower spray nozzle, comprising a housing, a pipe connector fixedly connected to the inlet of the housing, a bottom cover threadedly connected to the bottom of the housing, spray holes inside the bottom cover, a rotary motor located at the upper center of the bottom cover, a connecting shaft fixedly connected to the output shaft of the rotary motor passing through the bottom of the bottom cover, a brush strip fixedly connected to the bottom of the connecting shaft, bristles on the top of the brush strip being movably connected to the bottom cover, the rotary motor being electrically connected to a DSP controller, and a pressure sensor located inside the housing, which is electrically connected to the DSP controller. This desulfurization tower spray nozzle can effectively prevent the spray holes from clogging. The nozzle has an automatic cleaning function; when the spray holes are clogged, the brush cleans them promptly, preventing further clogging and increasing desulfurization efficiency.

[0004] The desulfurization tower spray nozzles provided by the aforementioned patent can effectively prevent nozzle clogging, but some problems still exist during use. For example, their spray range is limited, which cannot guarantee the uniform distribution of the desulfurizing agent in the tower, causing some exhaust gas to not fully contact the desulfurizing agent, thereby reducing the desulfurization effect.

The vortex nozzle 2 is arranged in two rows symmetrically along both sides of the inlet pipe 1. Both rows of vortex nozzles 2 are connected by rocker arms 3. The extension and retraction of the rocker arms 3 by the drive cylinder 4 drives the vortex nozzle 2 to rotate, thereby realizing the rotation and spraying of the vortex nozzle 2. This ensures that the desulfurizing agent sprayed by the vortex nozzle 2 is fully sprayed into the space inside the desulfurization tower, so as to achieve full contact between the waste gas and the desulfurizing agent and provide a desulfurization effect on the waste gas. The opening of the water spray end of the vortex nozzle 2 is larger than that of the traditional nozzle, which can avoid the particulate matter from clogging the nozzle.
