[0002] BYD (1,4-butynediol) is an intermediate product of BDO (1,4-butanediol). BYD is extracted from the liquid phase of the C104 distillation tower, filtered out impurities in F108 (bag filter), cooled in the cooler, and then put into the intermediate tank area for standby. In this production process, BYD needs to be sampled and tested every 8-12 hours to detect whether the BYD product after being filtered by the bag filter is qualified. The existing technology mainly performs replacement sampling through the BYD outlet pipeline. During the replacement sampling process, BYD The chemical characteristics are relatively viscous, so the pipeline is prone to crystallization and blockage, especially in winter. Before sampling, it is necessary to use steam to heat the pipeline to dredge it, or keep the liquid outlet of the pipeline in a liquid-discharging state to avoid BYD crystallization and blockage. If steam is used to heat the pipeline, it will cause trouble to the workers. If the pipeline is kept in a liquid-discharging state, it will not only lead to material waste, but also require analysts to use sampling buckets for large-scale replacement, increasing labor intensity. For this reason, a new high-viscosity product sampling device is provided to solve the above-mentioned problems. Utility Model Content

[0014] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0015] The utility model provides a novel high-viscosity product sampling device, comprising a cooler 1, wherein a circulating water inlet pipeline 2 is provided at the upper portion of a left end of the cooler 1, a circulating water outlet pipeline 3 is provided at the lower portion of a right end of the cooler 1, a BYD liquid inlet pipeline 4 is provided at the right side of the upper end of the cooler 1, a BYD liquid outlet pipeline 5 is provided at the left side of the lower end of the cooler 1, the BYD liquid inlet pipeline 4 and the BYD liquid outlet pipeline 5 are connected via a circulating pipeline 6, a sampling pipeline 7 is provided on the circulating pipeline 6, and a sampling valve 8 is provided on the sampling pipeline 7.

[0016] like Figure 1 As shown, after BYD is filtered by the bag filter, it enters the cooler 1 for cooling. The cooled BYD is then transported to the intermediate tank area through the BYD outlet pipeline 5 for standby. During the process of BYD flowing into the cooler 1 through the BYD inlet pipeline 4, a small amount of uncooled BYD will gradually enter the BYD outlet pipeline 5 along the circulation pipeline 6 and merge with the cooled BYD. A small amount of uncooled BYD has little effect on the temperature of the cooled BYD. As long as BYD is cooled by the cooler 1, the BYD in the circulation pipeline 6 will be continuously transported to the BYD outlet pipeline 5 to ensure that BYD is always flowing in the circulation pipeline 6. At the same time, since the BYD in the circulation pipeline 6 is in an uncooled state, The length of the sampling pipeline 7 does not exceed 10 mm, and the circulation pipeline 6 will conduct heat to the sampling pipeline 7, so that the sampling pipeline 7 is always in a heat-insulating state. Therefore, it can effectively solve the problem of sampling trouble caused by pipeline blockage during sampling in the prior art. In the process of BYD in the circulation pipeline 6 flowing to the BYD liquid outlet pipeline 5, part of the heat will be dissipated, so that the BYD temperature in the sampling pipeline 7 will not be too high, but not too low, so as to avoid the direct sampling temperature in the BYD liquid inlet pipeline 4 being too high and scalding the sampling personnel. When sampling is needed, since the length of the sampling pipeline 7 is relatively short, the sampling valve 8 can be opened to obtain a fresh BYD sample, and the BYD does not need to be kept in a liquid outlet state all the time, which reduces the waste of materials and can also ensure that the taken samples are fresh.

[0017] The inner diameter of the circulation pipeline 6 is smaller than one tenth of the inner diameter of the BYD liquid inlet pipeline 4 .

[0018] like Figure 1 As shown, the inner diameter of the circulation pipeline 6 is small, ensuring that most of the BYD is cooled by the cooler 1, causing a small amount of BYD in the BYD liquid inlet pipeline 4 to short-circuit and enter the BYD liquid outlet pipeline 5 along the circulation pipeline 6.

[0019] A safety valve 9 is provided on the top of the cooler 1 .

[0020] like Figure 1 As shown, before the BYD is cooled, the temperature of the BYD in the BYD liquid inlet pipeline 4 is as high as over 140°, so that when the BYD is cooled, water vapor may be generated in the cooler 1 during heat exchange with the circulating water. If it is not discharged in time, the pressure in the cooler 1 may be too high, affecting the use of the cooler 1. The pressure in the cooler 1 can be controlled in real time by the safety valve 9.

[0021] The cooler 1 comprises a left end cap 10, a shell 11 and a right end cap 12. The left end cap 10 and the right end cap 12 are respectively provided with a BYD liquid inlet 13 and a BYD liquid outlet 14. The BYD liquid inlet 13 and the BYD liquid outlet 14 are respectively connected to a BYD liquid inlet pipeline 4 and a BYD liquid outlet pipeline 5. The left end cap 10 and one end of the shell 11, and the right end cap 12 and the other end of the shell 11 are connected through a partition plate 15. A plurality of spirally distributed inner portions of the shell 11 are provided. BYD cooling pipe 16, the inlet ends of multiple BYD cooling pipes 16 pass through the partition 15 on one side of the right head 12 to be connected with the BYD liquid inlet 13, the outlet ends of multiple BYD cooling pipes 16 pass through the partition 15 on one side of the left head 10 to be connected with the BYD liquid outlet 14, and a cold water inlet 17 and a warm water outlet 18 are respectively provided at both ends of the cooler 1, the cold water inlet 17 is connected to the circulating water inlet pipeline 2, and the warm water outlet 18 is connected to the circulating water outlet pipeline 3.

[0022] like Figure 2 As shown, the BYD in the BYD liquid inlet pipeline 4 evenly enters into multiple BYD cooling pipes 16 through the BYD liquid inlet 13, thereby increasing the contact area between the BYD and the circulating water and improving the heat exchange rate; the cooled BYD is discharged from the BYD liquid outlet pipeline 5, and the spiral structure of the BYD cooling pipe 16 can increase the contact time between the BYD and the circulating water, further improving the heat exchange rate; the circulating water enters into the cooler 1 through the cold water inlet 17, and performs heat exchange with the BYD in the cooler 1 through the BYD cooling pipe 16, and the warm water generated by the heat exchange is discharged from the warm water outlet 17.

[0023] A plurality of D-shaped spoilers 20 are staggered up and down in the shell 11 and between the partitions 15 through support rods 19, and a plurality of diversion holes 21 are evenly opened on the D-shaped spoiler 20. The BYD cooling pipe 16 is a corrugated pipe made of stainless steel. The shape of the corrugated pipe can change the flow direction of the circulating water and play a role in spoiling the flow. During the flow of the circulating water, a certain impact force is exerted on the BYD cooling pipe 11, thereby reducing the accumulation of scale on the BYD cooling pipe 11.

[0024] like Figure 2As shown, the D-type spoiler 20 is staggered up and down in the cooler 1 to change the flow direction and flow rate of the circulating water in the cooler 1. The circulating water with a certain flow rate has a certain impact force on the BYD cooling pipe 16, further reducing the scaling of the BYD cooling pipe 16 and increasing the heat exchange effect. At the same time, the diversion hole 21 has a diversion effect, which can reduce the impact force of the circulating water on the D-type spoiler 20.

[0025] Working principle: After BYD is filtered by the bag filter, most of the BYD in the high temperature state flows evenly along the BYD inlet pipeline 4 to the BYD cooling pipe 16. At the same time, the cooled circulating water is transported from the circulating water inlet pipeline 2 to the cooler 1 through the water pump, and heat is exchanged with the BYD in the BYD cooling pipe 16, taking out the heat of BYD, and entering the circulating water outlet pipeline 3 along the warm water outlet 18 with the circulating water, and discharged from the cooler 1; a small amount of BYD in the BYD inlet pipeline 4 does not pass through the cooler 1 to cool down, and enters the circulating water outlet pipeline 3 along the circulating pipeline 6. The BYD enters the BYD liquid outlet pipeline 5 and is collected with the cooled BYD. The heat on the circulation pipeline 6 is transferred to the sampling pipeline 7, so that the sampling pipeline 7 is always in a heat preservation state to ensure that the BYD in the sampling pipeline 7 does not condense and crystallize. The valve 8 can be opened at any time during sampling. Traditionally, BYD is kept in a feeding state to avoid BYD blocking the pipeline. According to effective work statistics, in order to ensure the normal progress of sampling work, about 50KG of BYD material can be dropped to the ground every day, and about 19 tons of BDO can be added to the ground every year, generating an economic benefit of about 200,000 yuan.

[0026] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
