Description

Technical Field

[0001] This utility model relates to the field of petroleum refining fluid sampling technology, specifically an adsorber applied to a petroleum refining fluid sampling system. Background Technology

[0002] Chemical analysis is hailed as the "eyes" of chemical production; therefore, analytical results directly guide the production process. Sampling safety is a crucial link in the entire chemical analysis process. Thus, the sampling system plays a vital role in chemical production. Current sampling systems typically include a sampler and an adsorber. The sampler collects samples from petroleum refining fluids, while the adsorber treats the exhaust gas from the sampler, removing impurities and contaminants. Current adsorbers usually utilize activated carbon or other adsorbent materials to adsorb harmful substances in the exhaust gas. However, traditional adsorbers tend to become saturated with the adsorbent material after prolonged use, leading to decreased adsorption efficiency. Furthermore, replacing the adsorbent material is cumbersome, affecting the continuity and stability of the sampling system. Therefore, there is an urgent need for a new type of adsorber that facilitates the replacement of the packing material and easy cleaning, to address the problems existing in current technologies.

[0020] The technical solution of this utility model is described in further detail below with reference to the accompanying drawings, but the scope of protection of this utility model is not limited to the following description.

[0021] like Figures 2 to 4 As shown, an adsorber is used in a petroleum refining fluid sampling system. The adsorber 2 includes a tank, an exhaust and backflush pipe 214, a central shaft 215, a support bucket 211, and a lower switch structure.

[0022] The carrying hopper 211 is disposed in the tank body. The exhaust and backflush pipe 214 is rotatably connected to the top of the tank body. The exhaust and backflush pipe 214 is connected to the central shaft 215. The central shaft 215 is located in the tank body and is inserted into the carrying hopper 211. The bottom of the carrying hopper 211 is provided with the lower switch structure. The bottom of the central shaft 215 is connected to the lower switch structure for rotation to open or close the bottom of the carrying hopper 211.

[0023] The bearing hopper 211 is provided with adsorption filler 212, the side of the bearing hopper 211 is provided with a first mesh plate 210, the side of the tank is provided with an air inlet pipe 216, and the bottom of the tank is provided with a discharge port.

[0024] Specifically, the tank body includes an upper cover plate 202, an upper tank wall 203, a lower tank wall 204, and a lower cover plate 209. The top of the upper tank wall 203 is detachably connected to the upper cover plate 202 by bolts. The top of the carrying hopper 211 is detachably connected to the bottom of the upper tank wall 203 and the top of the lower tank wall 204 by bolts. The bottom of the lower tank wall 204 is detachably connected to the lower cover plate 209 by bolts. The discharge port is located on the lower cover plate 209. This utility model adopts a modular installation method, which is convenient for installation, disassembly, and maintenance.

[0025] The exhaust and backflushing duct 214 is rotatably mounted on the upper cover plate 202. A drive device 201 is mounted on the upper cover plate 202, connected to the exhaust and backflushing duct 214 and used to drive its rotation. The drive device 201 is existing technology, such as a motor, and can be connected to the exhaust and backflushing duct 214 via a belt, gears, or other means. The top of the exhaust and backflushing duct 214 extends out of the upper cover plate 202. The portion of the exhaust and backflushing duct 214 below the upper cover plate 202 has a funnel structure, while the portion extending out of the upper cover plate 202 has a tube structure. The exhaust and backflushing duct 214, the central shaft 215, and the supporting hopper 211 are coaxially arranged.

[0026] The adsorption filler 212 is a prior art material, such as nano-mineral crystals, activated carbon, bamboo charcoal bags, activated alumina, etc. A feeding port 217 is provided above the supporting hopper 211. Corresponding valves are provided on the top of the exhaust and backflushing pipe 214, the feeding port 217, the air inlet pipe 216, and the discharge port of this invention.

[0027] In practice, the valves on the feed port 217 and the discharge port are closed. The air inlet pipe 216 is connected to the exhaust end of the sampler 1 in the petroleum sampling system, and the exhaust gas is discharged into the air inlet pipe 216. The exhaust gas then enters the tank body and is located in the chamber between the lower tank wall 204 and the support hopper 211. Then the exhaust gas passes through the first mesh plate 210 and enters the interior of the support hopper 211. The particulate matter is sucked away by the adsorption packing 212. The gas continues to move upward in the support hopper 211 and is discharged through the exhaust and backflush pipe 214.

[0028] This invention includes an additional backflushing function for cleaning and replacing the adsorption packing 212, for cleaning the support hopper 211 and the first perforated plate 210. After the entire adsorber has been running for a long time, particles tend to accumulate on the outer surface of the first perforated plate 210, affecting the normal flow of gas. Furthermore, the adsorption packing 212 also needs to be replaced with new packing after prolonged use.

[0029] When the adsorption packing 212 needs to be replaced, the exhaust and backflushing pipe 214 is rotated by the drive device 201, causing the central shaft 215 to rotate as well. The central shaft 215 drives the lower switch structure to open the discharge port at the bottom of the tank, allowing the adsorption packing 212 to fall from the bottom of the support hopper 211 and be discharged through the discharge port. After the adsorption packing 212 is discharged, the valves on the feed port 217 and the air inlet pipe 216 are closed, and high-pressure backflushing gas is introduced through the exhaust and backflushing pipe 214. The high-pressure backflushing gas enters the support hopper 211 and cleans the first mesh plate 210 from the inside out, allowing the attached particles to pass through the first mesh plate 210, the lower switch structure, and the discharge port. After discharge, the valve on the discharge port is opened, allowing new adsorption packing 212 to be added through the feed port 217.

[0030] The exhaust and backflush duct 214 can be connected to a three-way valve at the end. The three-way valve is connected to the exhaust gas discharge duct and the high-pressure gas supply duct respectively. The high-pressure gas supply duct can be connected to the corresponding gas tank and other gas supply equipment.

[0031] This invention utilizes a first perforated plate 210 and adsorption packing 212 to form a two-layer adsorption function, effectively purifying waste gas in petroleum sampling systems. It also incorporates backflushing cleaning and adsorption packing 212 replacement functions. The rotation of the central shaft 215 opens or closes the bottom of the carrying hopper 211, allowing the adsorption packing 212 to be discharged. Further backflushing via the exhaust and backflushing pipe 214 achieves effective cleaning from the inside out. The exhaust and backflushing pipe 214 has multiple functions, including controlling the lower switch structure, discharging waste gas, and introducing high-pressure backflushing air, thus optimizing the overall structural design of the adsorber. Compared to existing technologies, this invention achieves highly efficient purification of waste gas in petroleum sampling systems, improving purification efficiency and quality, reducing operating costs and maintenance difficulty, ensuring long-term stable operation of the adsorber, and preventing equipment failures due to adsorption packing blockage or failure.

[0032] Furthermore, the carrying hopper 211 includes a funnel portion and a cylindrical portion. The cylindrical portion is a hollow cylindrical structure, and the top of the cylindrical portion is fixedly connected to the funnel portion. A first perforated plate 210 is provided on the side of the cylindrical portion, and an annular cavity is formed between the cylindrical portion and the inner side of the tank. The first perforated plate 210 is provided with multiple micropores to achieve preliminary filtration of the exhaust gas.

[0033] The gas discharged from sampler 1 may contain some sample, so the annular chamber between the straight section and the inner side of the tank can also store the waste sample, which is discharged together with the adsorption packing 212. It should be noted that the waste sample is stored in the space below the support hopper 211, which does not affect the gas entering the support hopper 211.

[0034] Furthermore, the lower switch structure includes an outer shell 205 and an inner baffle 208; the bottom of the carrying hopper 211 is provided with an opening, which is fixedly connected to the outer shell 205; the inner baffle 208 is rotatably connected to the inner side of the outer shell 205; the outer shell 205 is provided with a first through hole 207; the inner baffle 208 is provided with a second through hole 2071; the bottom of the central shaft 215 is fixedly connected to the inner baffle 208; the central shaft 215 is used to rotate the inner baffle 208 so that the first through hole 207 and the second through hole 2071 coincide or intersect.

[0035] The outer shell 205, the inner baffle 208, and the bottom of the tank are preferably conical. The first through hole 207 and the second through hole 2071 can be of various structures such as round holes or square holes, and multiple through holes can be provided. When the first through hole 207 and the second through hole 2071 are staggered, the bottom of the bearing hopper 211 is closed, so the adsorption packing 212 cannot be discharged. When the first through hole 207 and the second through hole 2071 coincide, the adsorption packing 212 can be discharged.

[0036] Furthermore, an annular baffle 218 is provided above the carrying hopper 211. The annular baffle 218 is fixedly connected to the inner wall of the tank body, and a second mesh plate is provided in the hollow part of the annular baffle 218.

[0037] The second perforated plate has a grid-like structure, ensuring that airflow passes upwards. The central shaft 215 passes through the second perforated plate.

[0038] Furthermore, the bottom of the exhaust and backflushing duct 214 is a funnel structure, and the inner wall of the funnel structure is fixedly connected to the top of the central shaft 215 via connecting rods 213. Multiple connecting rods 213 are provided, which does not affect the gas flow.

[0039] like Figure 1 The oil sampling system includes a sampler 1, which passes through a sample connection tube 105, cooler 103, and is connected to a sample collection tube 102. Cooler 103 is provided with a coolant inlet tube 101 and a coolant outlet tube 104. The sampler 1 is connected to a gas inlet tube 106 and a sample outlet tube 107. The exhaust end of the sampler 1 is connected to the air inlet tube 216 of the adsorber 2.

[0040] During collection, the sample enters the sampler 1 through the sample collection tube 102 and the sample connection tube 105, and is discharged through the sample discharge tube 107. A coil can be installed in the cooler 103, which connects the sample collection tube 102 and the sample connection tube 105. The cooler 103 cools the coil through the coolant inlet tube 101 and the coolant outlet tube 104, thereby cooling the sample.

[0041] When sampler 1 is emptied, gas is introduced through gas input pipe 106. The waste gas inside sampler 1 and some samples enter adsorber 2 to complete the purification of waste gas and the treatment of waste samples.
