Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for distillation column operations, specifically to an anti-clogging nozzle structure suitable for liquid phase reactor residue. Background Technology

[0002] Liquid bottom residue refers to the liquid at the bottom of a distillation column, which generally contains high-boiling-point substances, some feed liquid, and a small amount of solid impurities. During distillation, the liquid bottom residue is drawn out by a transfer pump and then sprayed into a separator via a spray system. The liquid separated by the separator is then transported to the high-boiling-point reactor to continue participating in the reaction. However, during this process, the spray system nozzles are easily clogged by solid impurities, affecting production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a reasonably structured and reliable anti-clogging nozzle structure suitable for liquid phase reactor residues, solving the problem that the nozzles of the spraying mechanism are easily clogged by solid impurities, and improving production efficiency.

[0004] The technical solution of this utility model is:

[0005] A clog-resistant nozzle structure suitable for liquid phase reactor residue includes a nozzle body, which consists of a front nozzle, an intermediate tube connected to the rear end of the front nozzle, and a delivery pipe connector connected to the rear end of the intermediate tube. The key technical features are: a filter plate is built into the rear part of the intermediate tube, and multiple filter holes are evenly distributed on the filter plate; a radial through hole corresponding to the material receiving side of the filter plate is provided on the outer wall of the intermediate tube; a pressure valve is fixed outside the radial through hole; and a retractable flexible pipe is connected to the other end of the pressure valve.

[0006] The above-mentioned anti-clogging nozzle structure suitable for liquid phase reactor residue has a cone-shaped front part with multiple spray holes evenly arranged, a circular cylindrical positioning cylinder at the rear of the front nozzle, an internal thread on the inner wall of the circular cylindrical positioning cylinder, and an external thread on the front of the outer wall of the intermediate tube that connects with the internal thread.

[0007] The above-mentioned anti-clogging nozzle structure suitable for liquid phase reactor residue has a radial positioning screw hole on the outer wall of the circular positioning cylinder of the front nozzle, and a positioning screw that presses against the outer wall of the intermediate tube is screwed into the radial positioning screw hole.

[0008] The aforementioned anti-clogging nozzle structure suitable for liquid phase reactor residue has a cylindrical positioning part on the edge of the filter plate that connects to the inner wall of the intermediate tube.

[0009] The above-mentioned anti-clogging nozzle structure suitable for liquid phase reactor residue has a rear flange at the rear end of the intermediate tube, a front flange connected to the rear flange of the delivery pipeline joint, and a reduced-diameter threaded ring at the front end of the delivery pipeline joint that is threaded to the inner surface of the rear part of the intermediate tube.

[0010] The beneficial effects of this utility model are:

[0011] By using a filter plate to filter the incoming material, when a large amount of deposited solid impurities causes poor flow, the pressure on the material-side of the filter plate increases to a set value. At this point, the pressure valve opens, and the incoming material, carrying the solid impurities, passes through the pressure valve to a retractable flexible pipeline, and is then sent to the collection device. After the solid impurities on the filter plate are removed, the pressure on the material-side of the filter plate decreases, the pressure valve closes, and the spraying operation continues. This invention solves the problem of the spray nozzles being easily clogged by solid impurities, thus improving production efficiency. Attached Figure Description

[0014] The present invention will be described in detail with reference to the accompanying drawings.

[0015] like Figure 1 As shown, the anti-clogging nozzle structure suitable for liquid phase reactor residue includes a nozzle body, which consists of a front nozzle 5, an intermediate pipe 4 connected to the rear end of the front nozzle 5, and a delivery pipeline connector 1 connected to the rear end of the intermediate pipe 4.

[0016] The intermediate tube 4 has a built-in filter plate 8 at the rear. The filter plate 8 has a plurality of filter holes evenly distributed on it. The outer wall of the intermediate tube 4 has a radial through hole corresponding to the material receiving side of the filter plate 8. A pressure valve 9 is fixed outside the radial through hole. The other end of the pressure valve 9 is connected to a retractable flexible pipeline 10.

[0017] In this embodiment, the front nozzle 5 is conical in shape with a plurality of spray holes 7 evenly arranged at its front. A cylindrical positioning cylinder is located at the rear of the front nozzle 5. The inner wall of the cylindrical positioning cylinder has internal threads, and the front of the outer wall of the intermediate tube 4 has external threads that connect with the internal threads. A radial positioning screw hole is provided on the outer wall of the cylindrical positioning cylinder of the front nozzle 5, and a positioning set screw 6 for pressing against the outer wall of the intermediate tube 4 is screwed into the radial positioning screw hole. The edge of the filter plate 8 has a cylindrical positioning part that connects to the inner wall of the intermediate tube 4. A rear flange 3 is provided at the rear end of the intermediate tube 4, and a front flange 2 connected to the rear flange 3 is provided on the delivery pipe connector 1. A reduced-diameter threaded ring 11 is provided at the front end of the delivery pipe connector 1 that is threaded to the inner surface of the rear part of the intermediate tube 4.

[0018] Working principle:

[0019] 1. During operation, the liquid phase reactor residue is drawn out through the transfer pump body and then transferred to the nozzle structure described in this utility model through the transfer pipeline connector 1.

[0020] 2. After the liquid phase reactor residue reaches position 8 of the filter plate, the solid impurities are filtered out.

[0021] 3. As the working time increases, more and more solid impurities are deposited on the filter plate 8. When the flow is obstructed and the pressure on the feed side of the filter plate 8 increases to the set value, the pressure valve 9 is opened. The liquid phase reactor residue, carrying solid impurities, passes through the pressure valve 9 to the retractable flexible pipeline 10, and is then sent to the collection device.

[0022] 4. After the solid impurities on the filter plate 8 are removed, the pressure on the material side of the filter plate 8 decreases, the pressure valve 9 closes, and the spraying operation continues.

[0023] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
