Description

Technical Field

[0001] This utility model relates to the field of chemical separation engineering technology; more specifically, it relates to a separator for the recovery and reuse of olefin separation condensate from methanol-to-olefins. Background Technology

[0002] Chemical industry, or chemical production, is a heavy industry sector dedicated to transforming raw materials into valuable products through chemical changes. Its core lies in using chemical reactions and physical processes to alter the structure of matter at the molecular level, thereby enabling the large-scale production of new materials. From a supply chain perspective, it is divided into upstream basic chemicals (such as acids, alkalis, inorganic salts, olefins, and aromatics) and midstream and downstream fine chemicals (such as pharmaceuticals, pesticides, dyes, and cosmetics). Its products permeate all aspects of life, from clothing and food to housing and transportation, making it a fundamental and pillar industry of the national economy, hailed as the "cornerstone of modern civilization."

[0003] In the methanol-to-olefins (MTO) process, the mixed gas produced by the reaction is quenched and compressed before entering the olefin separation unit. Water and some high-boiling-point hydrocarbons (such as C5+) condense in a low-temperature heat exchanger, forming "olefin separation condensate." This stream is mainly composed of water, with dissolved small amounts of alcohols (such as unreacted methanol), aldehydes, ketones, and C4-C6 hydrocarbons. It is corrosive and is typically sent to a wastewater treatment system for separation and purification. The recovered hydrocarbons can be used as fuel or further processed.

[0004] Currently, in the operation of existing chemical separation equipment, many devices often experience blockages in the distributor due to impurities in the condensate. This may require shutting down the condensation equipment and disassembling and repairing the distributor, which is time-consuming and labor-intensive, reducing the equipment's practicality. Furthermore, most existing equipment typically uses flanges to connect to the input and output pipes. When installing the equipment, threaded nuts are required, but these small nuts may fall off during operation, making installation inconvenient and reducing the equipment's applicability. Therefore, there is an urgent need for a methanol-to-olefins olefin separation condensate recovery and reuse distributor to solve these problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a methanol-to-olefins olefin separation condensate recovery and reuse diverter to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a methanol-to-olefins olefin separation condensate recovery and reuse diverter, comprising: a diverter main pipe, one end of which is provided with a filter structure, and the other end of which is fixedly connected to a diverter branch pipe; one end of the filter structure and both ends of the diverter branch pipe are provided with anti-drop quick-connect structures; one end of each of the three sets of anti-drop quick-connect structures is respectively provided with a water inlet pipe, a wastewater pipe, and a recovery pipe; ball valves are installed inside both ends of the diverter branch pipe and inside the water inlet pipe; the filter structure includes an installation pipe, an installation groove, a filter plate, a positioning hole, a positioning sleeve, a positioning rod, and a spring; the anti-drop quick-connect structure includes a first connecting plate, a second connecting plate, a connecting rod, a nut, a moving groove, a moving rod, a connecting groove, and a reinforcing groove.

[0007] Preferably, the mounting tube is fixedly connected to the outer surface of one end of the main diversion tube, and an mounting groove is provided inside the upper outer surface of the mounting tube. A filter plate is inserted into the mounting groove. Positioning holes are provided inside the outer surfaces of both sides of the filter plate. Positioning sleeves are fixedly connected to the outer surfaces of both sides of the mounting tube. A positioning rod is inserted into the positioning sleeve, and a spring is sleeved on the outer surface of the positioning rod. This design allows the positioning rod to move inside the positioning sleeve.

[0008] Preferably, the outer side of the filter plate is made of rubber, and the center of the filter plate is made of stainless steel. The internal dimensions of the mounting groove are adapted to the external dimensions of the filter plate. A support ring is fixedly connected to the outer surface of the positioning rod. The two ends of the spring abut against the surface of one side of the support ring and the inner wall surface of the positioning sleeve, respectively. The position of the positioning rod corresponds to the position of the positioning hole, and the external dimensions of one end of the positioning rod are adapted to the internal dimensions of the positioning hole. This design can prevent leakage at the connection between the mounting groove and the filter plate by utilizing the good elasticity and sealing properties of the material on the outer side of the filter plate.

[0009] Preferably, the first connecting plate is provided in three sets, and the three sets of first connecting plates are respectively fixedly connected to the outer surface of one end of the installation pipe and the outer surface of both ends of the branch pipe. The outer surface of one side of each of the three sets of first connecting plates is attached to a second connecting plate, and the outer surface of one side of each of the three sets of second connecting plates is respectively fixedly connected to the outer surface of one end of the inlet pipe, wastewater pipe and recovery pipe. The interior of each of the three sets of first connecting plates is fitted with a connecting rod, and there are multiple sets of connecting rods. The outer surface of one end of each of the multiple sets of connecting rods is threaded with a nut. The interior of each of the multiple sets of connecting rods is provided with a moving groove. The inner wall surface of one end of each of the multiple sets of nuts is fixedly connected with a moving rod. The outer surface of each of the three sets of second connecting plates is provided with a connecting groove, and there are multiple sets of connecting grooves. The inner wall surface of one end of each of the multiple sets of connecting grooves is provided with a reinforcing groove. This design allows the connecting rod to be hinged and rotated inside the first connecting plate.

[0010] Preferably, the positions of the multiple sets of connecting rods correspond to the positions of the multiple sets of connecting slots, and one end of each of the multiple sets of moving rods is fixedly connected to a limiting ring. The internal dimensions of the multiple sets of moving slots are adapted to the external dimensions of the multiple sets of limiting rings. This design allows the connecting rods to be inserted into the corresponding positions of the connecting slots after being hinged and rotated inside the first connecting plate.

[0011] Preferably, the outer diameter of the connecting rod is adapted to the inner diameter of the connecting groove, and the outer dimension of the other end of the nut is adapted to the inner dimension of the reinforcing groove. This design makes the connecting rod more stable when inserted into the connecting groove.

[0012] The technical effects and advantages of this utility model are as follows: By rotating the ball valve inside the water inlet pipe, the condensate inside the water inlet pipe can be cut off. At this time, the positioning rod can be pulled outward so that one end of the positioning rod is disengaged from the inside of the positioning hole. Then, the filter plate can be moved upward inside the mounting groove. Then, the unused filter plate can be inserted into the inside of the mounting groove for use. Therefore, it is not necessary to disassemble the entire main branch pipe. Moreover, it is more time-saving and labor-saving when replacing, which improves the practicality of the equipment to a certain extent.

[0013] By aligning the first and second connecting plates, the position of the connecting rod corresponds to the position of the connecting groove. The connecting rod can then be hinged and rotated, inserting itself into the connecting groove. Next, the nut can be rotated, inserting its other end into the reinforcing groove. Simultaneously, one end of the moving rod rotates and moves within the moving groove, thus connecting the first and second connecting plates. The cooperation of the first connecting plate, connecting rod, nut, moving groove, and moving rod prevents the connecting rod and nut from falling off, facilitating the installation of the main branch pipe. This avoids reducing the ease of installation of the main branch pipe, improving the applicability of the equipment to a certain extent. Furthermore, its overall structure is simple and reasonable in design, highly practical, and easy to promote and apply. Attached Figure Description

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The chemical separation engineering involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1, as Figures 1-4 As shown, this embodiment proposes a methanol-to-olefins olefin separation condensate recovery and reuse diverter, including: a main diverter 1, one end of which is equipped with a filter structure 2, and the other end of which is fixedly connected to a branch diverter 3. Both ends of the filter structure 2 and the branch diverter 3 are equipped with anti-drop quick-connect structures 4. One end of each of the three anti-drop quick-connect structures 4 is respectively equipped with a water inlet pipe 5, a wastewater pipe 6, and a recovery pipe 7. Ball valves 8 are installed inside both ends of the branch diverter 3 and inside the water inlet pipe 5. The filter structure 2 includes an installation pipe 21, an installation groove 22, a filter plate 23, a positioning hole 24, a positioning sleeve 25, a positioning rod 26, and a spring 27. The installation pipe 21 is fixedly connected to the outer surface of one end of the main diverter 1, and the upper outer surface of the installation pipe 21 has an installation groove 22 inside. Furthermore, a filter plate 23 is inserted inside the mounting groove 22. Positioning holes 24 are opened inside the outer surfaces of both sides of the filter plate 23. Positioning sleeves 25 are fixedly connected to the outer surfaces of both sides of the mounting tube 21. Positioning rods 26 are inserted inside the positioning sleeves 25. Springs 27 are sleeved on the outer surface of the positioning rods 26. The outer side of the filter plate 23 is made of rubber, and the center of the filter plate 23 is made of stainless steel. The internal dimensions of the mounting groove 22 are adapted to the external dimensions of the filter plate 23. A support ring is fixedly connected to the outer surface of the positioning rods 26. The two ends of the springs 27 abut against the surface of one side of the support ring and the inner wall surface of the positioning sleeves 25, respectively. The position of the positioning rods 26 corresponds to the position of the positioning holes 24, and the external dimensions of one end of the positioning rods 26 are adapted to the internal dimensions of the positioning holes 24.

[0021] In this embodiment, the design, through the good elasticity and sealing of the outer material of the filter plate 23, can prevent liquid leakage at the connection between the mounting groove 22 and the filter plate 23. Furthermore, the corrosion resistance of the material at the center of the filter plate 23 can improve its service life. This design also makes the filter plate 23 more stable when inserted into the mounting groove 22. At the same time, this design allows the positioning rod 26 to move inside the positioning sleeve 25 and then return to its original position under the elasticity of the spring 27. One end of the positioning rod 26 is inserted into the positioning hole 24 to position the filter plate 23 inside the mounting groove 22.

[0022] Ball valve 8 is a product that can be purchased directly on the market. Its principle, connection method and control method are existing technologies that are well known to those skilled in the art, so they will not be described in detail here.

[0023] Example 2, as Figure 2 and Figure 4 As shown, based on the same concept as the above embodiment, this embodiment also proposes: the anti-fall quick-installation structure 4 includes a first connecting plate 41, a second connecting plate 42, a connecting rod 43, a nut 44, a moving groove 45, a moving rod 46, a connecting groove 47, and a reinforcing groove 48. The first connecting plate 41 is provided in three sets, and the three sets of first connecting plates 41 are respectively fixedly connected to the outer surface of one end of the installation pipe 21 and the outer surfaces of both ends of the branch pipe 3. The outer surfaces of one side of each of the three sets of first connecting plates 41 are fitted with a second connecting plate 42, and the outer surfaces of one side of each of the three sets of second connecting plates 42 are respectively fixedly connected to the outer surfaces of one end of the inlet pipe 5, the wastewater pipe 6, and the recovery pipe 7. The interior of each of the three sets of first connecting plates 41 is fitted with a connecting rod 43, and multiple sets of connecting rods 43 are provided. The outer surfaces of one end of each set of connecting rods 43 are threaded with a nut 44. The interior of each set of connecting rods 43 is provided with a moving groove 45, and the inner wall surface of one end of each set of nuts 44 is fixedly connected with a moving groove 46. The outer surfaces of the rod 46 and the three sets of second connecting plates 42 are all provided with connecting grooves 47, and there are multiple sets of connecting grooves 47. The inner wall surface of one end of each set of connecting grooves 47 is provided with a reinforcing groove 48. The positions of the multiple sets of connecting rods 43 correspond to the positions of the multiple sets of connecting grooves 47. One end of each set of moving rods 46 is fixedly connected to a limiting ring. The internal dimensions of the multiple sets of moving grooves 45 are adapted to the external dimensions of the multiple sets of limiting rings. This design allows the connecting rods 43 to be inserted into the connecting grooves 47 by hinged rotation, making the connecting rods 43 more stable when inserted into the connecting grooves 47. This design also allows the moving rods 46 to rotate synchronously inside the moving grooves 45 when the nut 44 rotates at one end of the connecting rod 43, thereby preventing the nut 44 from falling off. At the same time, it makes the moving rods 46 more stable when moving inside the moving grooves 45, thereby improving the stability when one end of the connecting rod 43 is threadedly engaged with the nut 44.

[0024] The outer diameter of the connecting rod 43 is matched with the inner diameter of the connecting groove 47, and the outer diameter of the other end of the nut 44 is matched with the inner diameter of the reinforcing groove 48. This design makes the connecting rod 43 more stable when inserted into the connecting groove 47 and avoids the connecting rod 43 from shaking inside the connecting groove 47. In addition, this design allows the other end of the nut 44 to be inserted into the reinforcing groove 48 to position the first connecting plate 41 and the second connecting plate 42.

[0025] The connecting rod 43 and nut 44 in this application, as well as all movable parts, require regular cleaning and maintenance, including but not limited to dust removal and lubrication.

[0026] Working principle: When using the equipment, the ball valve 8 inside the inlet pipe 5 is closed by rotation. Then, the positions of the first connecting plate 41 and the second connecting plate 42 are aligned, and the position of the connecting rod 43 corresponds to the position of the connecting groove 47. At this time, the connecting rod 43 can be hinged and rotated, so that the connecting rod 43 is inserted into the inside of the connecting groove 47. Then, the nut 44 can be rotated, so that the nut 44 is threaded onto the outer surface of one end of the connecting rod 43, and the moving rod 46 rotates and moves synchronously inside the moving groove 45, so that the other end of the nut 44 is inserted into the inside of the reinforcing groove 48, thereby connecting the first connecting plate 41 and the second connecting plate 42. The above operation can be repeated to connect the inlet pipe 5 to the filter structure 2, the wastewater pipe 6, and the recovery pipe 7 to the branch pipe 3, thereby quickly completing the installation of the main branch pipe 1. The connection of the first connecting plate 41, connecting rod 43, nut 44, moving groove 45, and moving rod 46 prevents the connecting rod 43 and nut 44 from falling off. Then, the ball valves 8 inside the inlet pipe 5 and the branch pipe 3 can be rotated in sequence for use. When the filter plate 23 needs to be replaced, the condensate inside the inlet pipe 5 can be blocked by rotating the ball valve 8 inside the inlet pipe 5 again. At this time, the positioning rod 26 can be pulled outward so that one end of the positioning rod 26 is disengaged from the positioning hole 24. The filter plate 23 can then be moved upward inside the mounting groove 22. Then, the unused filter plate 23 can be inserted into the mounting groove 22. The old filter plate 23 can then be cleaned and dried for the next replacement, so that the entire branch pipe 1 does not need to be disassembled. The above is the complete working principle of this utility model.

[0027] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
