Description

Technical Field

[0001] This invention belongs to the technical field of butyl rubber preparation equipment, and relates to a granule water conveying system in a butyl rubber production device, and more particularly to an optimized design of a granule water conveying system for a butyl rubber device. Background Technology

[0002] In butyl rubber plants, the granule water plays a crucial role as the carrier for the movement of granules throughout the entire production process. As a carrier, the granule water receives granules in the polymerization unit and is then pumped to the halogenation unit, where the granules are released. The filtered water is then pumped back to the polymerization unit to collect granules again, forming a complete cycle.

[0003] In actual operation, the smoothness of the colloidal water circulation becomes a crucial factor restricting production. The existing colloidal water circulation system relies entirely on pumps for power; if the pumps malfunction, the colloidal water circulation will be terminated. This disrupts the circulation system, forcing a production shutdown and severely limiting the plant's capacity.

[0004] Therefore, finding a suitable way to solve the problems existing in the current butyl rubber production process and ensure the stable operation of the production process has become one of the urgent problems to be solved by many front-line researchers in this field. Summary of the Invention

[0056] This invention provides a granule water conveying system in a butyl rubber production apparatus. The conveying system connects the polymerization unit and the halogenation unit of the butyl rubber. The conveying system includes: a flash tank of the polymerization unit; a first granule water impeller pump connected to the liquid phase outlet pipeline of the flash tank; a stripping tower of the polymerization unit connected to the outlet of the first granule water pump; a second granule water impeller pump connected to the liquid phase outlet pipeline of the stripping tower; a halogenation unit connected to the outlet of the second granule water pump; a third granule water impeller pump connected to the filtered process water outlet pipeline of the halogenation unit; and a polymerization unit connected to the outlet of the third granule water pump. The first and second granule water impeller pumps are closed-loop impeller pumps. Compared with existing technologies, this invention argues that, based on the cationic polymerization reaction of butyl rubber, which requires a vigorous reaction at extremely low temperatures to generate the desired rubber, uneven granule size can occur when the reaction is unstable. Due to the small impeller clearance and high granule viscosity, large granules can cause pump blockage and reduced flow. These particles, due to pressure, will become larger and accumulate more within the pump chamber. This causes blockage in the water circulation, ultimately leading to a halt in the reaction and abnormal production.

[0057] Based on this, the present invention has specially designed a new colloidal water conveying system, which adopts a specific equipment connection sequence and a closed impeller pump designed with specific parameters. By setting the operating parameters of the entire conveying system, the conveying of colloidal water is optimized, avoiding equipment shutdowns and stoppages due to pump blockage, thus reducing the frequency of pump blockage and laying a good foundation for extending the reaction cycle.

[0058] Based on the actual working conditions and connection sequence of specific devices before and after, this invention adjusts and replaces the impeller form and pump body parameter design, optimizes the conveying form of granulated water, extends the stable operation cycle of the granulated water system, reduces the frequency of pump blockage and cleaning, and naturally reduces the risk of device shutdown caused by the cessation of granulated water circulation, thus extending the stable operation time of the device, reducing the output of defective granulated water, and improving the product qualification rate.

[0061] To further understand the present invention, preferred embodiments of the present invention are described below in conjunction with examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention and not for limiting the claims of the present invention.

[0062] There are no particular restrictions on the source of any raw materials used in this invention; they can be purchased from the market or prepared using conventional methods known to those skilled in the art.

[0063] There are no particular restrictions on the purity of any of the raw materials used in this invention. Preferably, industrial-grade pure or conventionally used purity in the production and preparation of butyl rubber is sufficient.

[0064] All terms and abbreviations used in this invention are conventional terms and abbreviations in the field. Each term and abbreviation is clear and distinct in its relevant application area, and those skilled in the art can understand it clearly, accurately, and uniquely based on the terms and abbreviations.

[0065] This invention provides a butyl rubber granule water conveying system, wherein the conveying system is connected between the polymerization unit and the halogenation unit of butyl rubber;

[0066] The conveying system includes:

[0067] Flash tank of the polymerization unit;

[0068] A first colloidal water impeller pump connected to the liquid phase outlet pipeline of the flash tank;

[0069] The stripping tower of the polymerization unit connected to the outlet of the first colloid pump;

[0070] A second colloidal water impeller pump connected to the liquid phase outlet pipeline of the stripping tower;

[0071] A halogenation unit connected to the outlet of the second colloidal water pump;

[0072] A third colloidal water impeller pump is connected to the filtered process water outlet pipeline of the halogenation unit.

[0073] The polymerization unit is connected to the outlet of the third granule water pump;

[0074] The first and second colloid water impeller pumps are closed impeller pumps.

[0075] In this invention, the impeller of the closed impeller pump is preferably a rear-mounted impeller.

[0076] In this invention, the volute height radius of the closed impeller pump is preferably 245 mm.

[0077] In this invention, the volute width of the closed impeller pump is preferably 175 mm.

[0081] See Figure 1 , Figure 1 The equipment layout diagram shows the structure and dimensions of the closed impeller pump provided by the present invention.

[0082] Depend on Figure 1 It can be seen that the closed impeller pump used in this invention has a larger volute height (245mm) and volute width (175mm), which increases the gap between the impeller and the volute. Combined with the overall system optimization design, it makes it easier for granules to pass through smoothly.

[0083] Furthermore, this invention employs a closed impeller with a maximum impeller clearance of 1.5mm. The impeller inlet end features both an impeller sealing ring and a pump body sealing ring. This structure can accommodate larger particles, allowing them to pass through smoothly. It reduces the squeezing force between the impeller and the volute, decreasing the likelihood of particles agglomerating and thus lowering the frequency of pump blockage.

[0084] The closed-loop impeller pump provided by this invention features an enlarged volute volume and a changed impeller design, resulting in looser, less caking granules after pump blockage. This facilitates cleaning after pump shutdown and allows for rapid removal of granules from the pump chamber. This reduces processing time and improves work efficiency.

However, it should be understood that these embodiments are implemented under the premise of the technical solution of the present invention, and provide detailed implementation methods and specific operating procedures. They are only for further illustrating the features and advantages of the present invention, and are not intended to limit the scope of the claims of the present invention. The scope of protection of the present invention is not limited to the following embodiments.

[0126] Example 1

[0127] Butyl rubber granule water conveying system in butyl rubber production plant:

[0128] Polymerization section: Flash tank V135 / 145 / 155, Stripping tower V148 / V160;

[0129] Halogenation section: T500, P500, T501, P501, T505, P505;

[0130] In this context, T represents the storage tank, i.e., T500 represents storage tank 500 and T501 represents storage tank 501.

[0131] P represents a pump, meaning P500 represents a medium transfer pump for storage tank 500.

[0132] The system process is as follows:

[0133] Flash evaporator V135 / 145 / 155 → Glue pump → Stripping tower V148 / V160 → Glue pump → T500 → P500 → T501 → P501 → T505 → P505 → Flash evaporator V135 / 145 / 155

[0134] Among them, the granule water pump, P500 and P501 are all closed impeller pumps.

[0135] The structure and dimensions of a closed impeller pump are as follows: Figure 1 As shown.

[0136] See Table 1, which shows the specific parameters of the rubber granule water conveying system in the butyl rubber production apparatus provided by the present invention.

[0139] The granule water conveying system provided by this invention in the production of butyl rubber was actually verified.

[0140] Before the optimized design of the conveyor system, the production system experienced a total of 22 anomalies in the first three quarters of 2020, 12 of which were due to pump blockage. After the optimization, the total number of anomalies in the fourth quarter (starting in October) was 10, with 2 of them being due to pump blockage. In the following year, 2021, only one pump blockage occurred. Furthermore, disassembly and inspection revealed that the rubber blocks inside the pump chamber were relatively loose, and the processing speed was significantly improved compared to before.

[0141] See Figure 2 , Figure 2 This is a partial screenshot of the statistical ledger of all device anomaly analysis in 2020 provided by the present invention.

[0142] It should be noted that cleaning a clogged pump takes approximately one hour. During this time, the produced adhesive will be classified as Grade B (normally Grade A; Grade A is supplied to large customers, and Grade B is supplied to smaller customers with less stringent requirements). This portion of adhesive will be separately marked and tested. If it passes the test, it will be classified as Grade B; otherwise, it will be classified as defective. This affects the product pass rate by approximately 0.5%, meaning the product pass rate can be improved by about 0.5%.
