Technical Field

[0001] This utility model relates to the field of desulfurizing agent nozzle connection technology, specifically a desulfurizing agent nozzle connection device for dry flue gas desulfurization. Background Technology

[0002] When treating waste gas generated from chemical processes, desulfurization towers are used for desulfurization. Desulfurizing agent is sprayed out through desulfurizing agent nozzles to mix evenly with the rising waste gas. During the mixing process, the desulfurization effect is achieved. To facilitate the maintenance of desulfurizing agent nozzles, flange structures are usually used to connect the desulfurizing agent.

[0003] Chinese Patent Publication No. CN222446008U discloses a "Connecting Device for Desulfurizing Agent Spray Pipe in Dry Flue Gas Desulfurization," which includes a desulfurizing agent conveying pipeline A, a standard flange A, a desulfurizing agent conveying pipeline B, a desulfurizing agent spray pipe, a non-standard flange, a standard flange B, an outer sleeve, and a desulfurization reactor. The desulfurizing agent conveying pipeline A, the desulfurizing agent conveying pipeline B, and the desulfurizing agent spray pipe are all connected by flanges. The desulfurizing agent spray pipe is fitted inside the non-standard flange and welded to it. The desulfurizing agent spray pipe extends into the desulfurization reactor. A gap is left between the desulfurizing agent spray pipe and the outer wall of the desulfurization reactor for easy removal of the spray pipe. An outer sleeve is installed between the non-standard flange on the outer wall of the desulfurizing agent spray pipe and the outer wall of the desulfurization reactor. The outer sleeve is welded to the outer wall of the desulfurization reactor. The other end of the outer sleeve is connected to the non-standard flange of the desulfurizing agent spray pipe by a flange. This connecting device is easy to disassemble and facilitates the maintenance or replacement of the desulfurizing agent spray pipe.

[0004] In existing technologies, the desulfurizing agent spray pipes can be connected by bolts using a flange structure. However, disassembly and installation still require tools to install and remove multiple sets of bolts, which takes a long time. Utility Model Content

[0005] The purpose of this utility model is to provide a flue gas dry desulfurization desulfurizing agent nozzle connection device to solve the problem in the above-mentioned background technology that tools are still needed to install and disassemble multiple sets of bolts during disassembly and installation, which takes a long time.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a flue gas dry desulfurization desulfurizing agent spray pipe connection device, including a desulfurization tower, wherein a quick splicing component is provided on the front side of the desulfurization tower, and the quick splicing component is used to realize quick connection of the pipeline structure, wherein an adjustment component is provided on the inner side of the quick splicing component, and the adjustment component is used to increase the extrusion pressure and improve the sealing performance by adjustment.

[0007] The quick splicing assembly includes a limiting plate, and right-angle pressure plates are provided on the inner sides of the top and bottom of the limiting plate. A limiting rod is installed on the front side of the end of the right-angle pressure plate, and a movable ring is movably spliced ​​on the outer side of the limiting rod.

[0008] The adjustment assembly includes an adjustment knob, which is located in the center of the front of the right-angle pressure plate. An adjustment screw is provided on the back of the adjustment knob, and a movable bracket is provided on the outer side of the end of the adjustment screw.

[0009] Preferably, an outer sleeve is installed on the back of the limiting plate, and the outer sleeve is located on the front of the desulfurization tower. Several sets of positioning grooves are opened on the front of the limiting plate.

[0010] Preferably, two sets of limiting plates are provided on both sides of the limiting plate, and the limiting plates are located outside the right-angle pressure plate, and a spray pipe is embedded in the inner side of the outer sleeve.

[0011] Preferably, the right-angle pressure plate has limit shafts on both sides at one end, and the limit shafts are located inside the limit plate. A baffle is installed in the middle of the limit rod, and a pin groove is opened on the limit rod near the baffle. A magnetic pin is movably arranged inside the pin groove.

[0012] Preferably, a combined bearing is provided on the outer side of the adjusting screw near the adjusting knob, and the combined bearing is embedded in the inner side of the right-angle pressure plate.

[0013] Preferably, two sets of limiting guide rods are installed on the back of the right-angle pressure plate, and the limiting guide rods are located inside the movable bracket.

[0014] Preferably, a combination plate is installed in the middle of the nozzle, and the combination plate is located on the front of the limiting plate.

[0016] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0017] First, this utility model, by installing a quick-assembly component, can provide an installation position for the outer structure using a limiting plate. By setting a flip-up right-angle pressure plate, the combined plate can be squeezed by the support wheels. After flipping, the limiting rod will face the front. The movable ring and the limiting rod can be spliced ​​together by sliding. The movable ring can restrict the right-angle pressure plate. By splicing, the clamped right-angle pressure plate can be quickly restricted, thereby achieving the effect of quick disassembly and installation of the inner nozzle.

[0018] Secondly, this utility model, by installing an adjustment component, addresses the issue that when a quick-assembly component is installed, the thickness of the inner sealing gasket varies, causing the limiting rod to be unable to be completely parallel to the nozzle after the right-angle pressure plate is flipped. By installing an adjustment knob, the adjustment screw can be driven, and rotation can cause the movable bracket to move laterally. By adjusting, the position of the support wheel can be changed, thus ensuring that the limiting rod remains parallel to the nozzle even when using sealing gaskets of different thicknesses, and guaranteeing that the movable ring can be combined with the limiting rod.
