Description

Technical Field

[0001] This invention relates to the field of hydrogen chloride conveying technology, specifically to a hydrogen chloride self-pressurized conveying and drying device. Background Technology

[0002] The production process of di(trichloromethyl) carbonate is accompanied by a large amount of hydrogen chloride byproducts. Currently, similar chlorination chemical production processes, such as chlorinated paraffin, chlorotoluene, and chloroacetic acid, also produce a large amount of hydrogen chloride byproducts. When hydrogen chloride is transported to the collection equipment, the hydrogen chloride gas is usually transported through the drying equipment under its own flow pressure. Since the flow rate of the transported hydrogen chloride gas will change constantly, it is easy for the transport pressure of the hydrogen chloride gas to be insufficient under its own pressure. At the same time, it is also easy for the gas flowing into the collection equipment to flow back, causing the transported hydrogen chloride gas to be contaminated. This affects the stability of the gas flow and the transport efficiency of hydrogen chloride gas under its own pressure. Summary of the Invention

[0007] Furthermore, the guiding mechanism includes an inclined plate installed inside the conveying mechanism, and the guiding mechanism also includes: The movable component is installed on the side wall of the inclined plate; Auxiliary components are installed on the side wall of the active component.

[0008] Furthermore, the buffer assembly includes a buffer tank fixedly connected to the top of the main body, an air inlet pipe fixedly connected to the front of the buffer tank, and a liquid outlet pipe fixedly connected to the bottom of the buffer tank. The top of the buffer tank is bolted to a connecting pipe.

[0009] Furthermore, the drying assembly includes a drying tank fixedly connected to the top of the main body, with one end of the connecting pipe away from the buffer tank extending into the interior of the drying tank, and the outer surface of the connecting pipe located outside the drying tank being bolted to the top of the drying tank; The bottom of the drying tank is fixedly connected to an inlet pipe, and the bottom of the drying tank is fixedly connected to an outlet pipe.

[0010] Furthermore, the connecting assembly includes a conveying pipe fixedly connected inside the two connecting frames, with an intermediate pipe fixedly connected to the side of the conveying pipe near the drying tank; The side of the intermediate pipe away from the conveying pipe is bolted to the side wall of the drying tank, and a spiral pipe is bolted to the back of the conveying pipe. The delivery pipe is connected to the interior of the drying tank through an intermediate pipe, and a notch is provided on the bottom inner wall of the intermediate pipe.

[0011] Furthermore, the pressurization assembly includes a conical tube one fixedly connected inside the delivery pipe, a conical tube two slidably connected to the side wall of the conical tube one, and an inlet groove opened on the side wall of the conical tube two. The outer surface of the conical tube 2 is rotatably connected with several ball bearings, and the inside of the inlet groove is fixedly connected with a telescopic frame.

[0012] Furthermore, the inclined plate is rotatably connected inside the intermediate tube, and the side wall of the inclined plate is rotatably connected to the central axis of the telescopic frame. The movable component includes a horizontal plate fixedly connected inside the middle tube, and several S-plates are rotatably connected to the outer surface of the horizontal plate, with the S-plates arranged at equal intervals.

[0013] Furthermore, a semi-circular plate is fixedly connected to the side wall of the S plate, and a tapered groove is opened on the side wall of the semi-circular plate. Several bending springs are fixedly connected to the side wall of the inclined plate, and the ends of the several bending springs away from the inclined plate are fixedly connected to the inner wall of the intermediate tube. The auxiliary component includes a curved plate 1 fixedly connected to the side wall of the S plate, and the side wall of the curved plate 1 has several tapered holes. Bending plate two is fixedly connected to the side wall of bending plate one.

[0014] The present invention has the following beneficial effects: 1. This invention, by changing the gas delivery pressure or flow rate of the high-pressure gas delivery equipment, can increase the pressure of hydrogen chloride gas during transmission in real time. Subsequently, as the gas continues to flow, it passes through a spiral tube. When the gas flows through the spiral tube, the multiple spiral structures inside the spiral tube can stabilize the turbulent flow of the gas. By increasing the pressure during hydrogen chloride delivery and ensuring the stability of gas flow, the gas delivery efficiency can be improved while reducing the possibility of backflow of gas delivered to the collection equipment, which could cause pollution during gas delivery, thus improving delivery efficiency.

[0015] 2. This invention, by enlarging the inlet, can adjust the flow area of ​​the gas entering the first and second conical tubes. It also ensures timely adjustment of the hydrogen chloride gas intake, reducing the risk of flow separation and stalling caused by decreased pressure due to reduced hydrogen chloride gas volume in the tank, which would otherwise occur during real-time pressure adjustment. This allows the gas to be smoothly drawn into the first and second conical tubes, improving the stability of the gas delivery process.

[0016] 3. This invention, through the shaking of the S-plate and the guidance of the bending plate two for the gas, ensures that the gas can be adsorbed into the cone tubes one and two regardless of whether the inlet between the cone tube one and the cone tube two is expanding or contracting. This reduces the situation where some gas flowing through the intermediate tube is blocked by the cone tube two when the inlet size between the cone tube one and the cone tube two is in a normal state, causing some gas to flow back before entering the cone tubes one and two in the intermediate tube. This further ensures stable gas delivery and improves the delivery efficiency and continuity of gas delivery.

[0017] 4. This invention, by capturing the liquid contained in the gas, can reduce the corrosion caused by corrosive mist particles entering between conical tube one and conical tube two, resulting in pitting on their surface. At the same time, it can also reduce the number of mist particles entering the collection device with the gas, thereby improving the gas drying intensity and enhancing the uniformity and intensity of gas delivery when it is drawn in.

[0018] 5. This invention, by reverse flow and impact on the conical holes on the curved plate, can reduce the situation where the conical holes are blocked by water film due to long-term capture of water mist particles in the gas. This improves the stability of water mist particle capture and also reduces the flow obstruction of some liquid at one side wall of the curved plate caused by the water film blocking the conical holes. This further reduces backflow of gas when passing through the curved plate and enhances the continuity and stability of gas flow.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-11 As shown, the present invention is a self-pressurized hydrogen chloride conveying and drying device, including a main body 1, a support frame 101 fixedly connected to the top of the main body 1, and further including: Conveying mechanism 2 is installed on the top of the support frame 101 and is used to pressurize the gas in real time during gas delivery. The guiding mechanism 3 is installed inside the conveying mechanism 2 to prevent the gas from being blocked and flowing back during gas conveying.

[0025] Entity 1 includes: Buffer assembly 11 is installed on the top of the main body 1; Drying assembly 12 is installed on the side wall of the main body 1.

[0026] The conveying mechanism 2 includes two connecting frames 201 bolted to the top of the support frame 101, and the conveying mechanism 2 also includes: Connecting component 21 is installed inside the two connecting brackets 201; The booster assembly 22 is installed inside the connecting assembly 21.

[0027] The guiding mechanism 3 includes an inclined plate 301 installed inside the conveying mechanism 2, and the guiding mechanism 3 also includes: The movable component 31 is installed on the side wall of the inclined plate 301; Auxiliary component 32 is installed on the side wall of active component 31.

[0028] The buffer assembly 11 includes a buffer tank 111 fixedly connected to the top of the main body 1. An air inlet pipe 112 is fixedly connected to the front of the buffer tank 111, and a liquid outlet pipe is fixedly connected to the bottom of the buffer tank 111. The top of the buffer tank 111 is bolted to a connecting pipe 113.

[0029] The drying assembly 12 includes a drying tank 121 fixedly connected to the top of the main body 1. One end of the connecting pipe 113 away from the buffer tank 111 extends into the interior of the drying tank 121. The outer surface of the connecting pipe 113 located outside the drying tank 121 is bolted to the top of the drying tank 121. The bottom of the drying tank 121 is fixedly connected to the liquid inlet pipe 122 and the bottom of the drying tank 121 is fixedly connected to the liquid outlet pipe 123. The liquid inlet pipe 122 and the liquid outlet pipe 123 are respectively connected to the conveying pipe and the discharge pipe of concentrated sulfuric acid. After the connection is completed, the staff connects the intermediate pipe 212 to the drying tank 121 and then connects the front of the conveying pipe 211 to the external high-pressure gas conveying equipment.

[0030] The connecting assembly 21 includes a conveying pipe 211 fixedly connected inside the two connecting frames 201, and an intermediate pipe 212 fixedly connected to the side of the conveying pipe 211 near the drying tank 121. The side of the intermediate pipe 212 away from the conveying pipe 211 is bolted to the side wall of the drying tank 121, and the back of the conveying pipe 211 is bolted to the spiral pipe 213. The delivery pipe 211 is connected to the interior of the drying tank 121 through the intermediate pipe 212. The bottom inner wall of the intermediate pipe 212 has a notch groove. When the gas continues to flow, it will pass through the spiral pipe 213. When the gas flows through the spiral pipe 213, the multiple spiral structures inside the spiral pipe 213 can make the turbulent flow of the gas flow smooth.

[0031] The pressurization assembly 22 includes a conical tube 221 fixedly connected inside the delivery pipe 211, a conical tube 222 slidably connected to the side wall of the conical tube 221, and an inlet groove opened on the side wall of the conical tube 222. The outer surface of the conical tube 222 is rotatably connected with several ball bearings, and the inside of the inlet groove is fixedly connected with a telescopic frame 223.

[0032] The inclined plate 301 is rotatably connected to the inside of the intermediate tube 212, and the side wall of the inclined plate 301 is rotatably connected to the central axis of the telescopic frame 223. The active component 31 includes a horizontal plate 311 fixedly connected inside the intermediate tube 212. Several S-plates 312 are rotatably connected to the outer surface of the horizontal plate 311, and the S-plates 312 are arranged at equal intervals.

[0033] A semicircular plate 313 is fixedly connected to the side wall of the S plate 312. A tapered groove is provided on the side wall of the semicircular plate 313. Several bending springs are fixedly connected to the side wall of the inclined plate 301. The ends of the several bending springs away from the inclined plate 301 are fixedly connected to the inner wall of the intermediate tube 212. The auxiliary component 32 includes a curved plate 321 fixedly connected to the side wall of the S plate 312, and the side wall of the curved plate 321 has a plurality of tapered holes. A second curved plate 322 is fixedly connected to the side wall of the first curved plate 321. Since several conical holes are opened on the side wall of the first curved plate 321, when some gas flows through the conical holes, the first curved plate 321 and the several conical holes opened on the side wall will capture the residual liquid hydrogen chloride or sulfuric acid mist in the gas.

[0034] In use, first connect the inlet pipe 112 to the source pipe from which hydrogen chloride gas is discharged. Then connect the bottom drain pipe to the external recovery equipment. Simultaneously, connect the inlet pipe 122 and the outlet pipe 123 to the concentrated sulfuric acid delivery and discharge pipes, respectively. After connection, the operator connects the intermediate pipe 212 to the drying tank 121, then connects the front of the delivery pipe 211 to the external high-pressure gas delivery equipment. Next, connect the spiral pipe 213 to the equipment that needs to receive the gas. After all installation is complete, hydrogen chloride gas is delivered into the support frame 101, and then concentrated sulfuric acid is delivered into the drying tank 121 through the inlet pipe 122, occupying part of the space at the bottom of the drying tank 121. When the gas enters the support frame... When the gas is inside the carrier 101, the space inside the carrier 101 can buffer and store the gas flow. At the same time, a small amount of liquid carried in the gas will settle to the bottom of the carrier 101 due to the reduced flow rate and be periodically discharged through the drain pipe. Then, the gas inside the carrier 101 will enter the drying tank 121 through the connecting pipe 113 under its own flow pressure. When the gas enters the drying tank 121, it will come into contact with the concentrated sulfuric acid inside the drying tank 121. At this time, the water vapor in the gas will be quickly absorbed by the concentrated sulfuric acid, thereby completing the drying of the gas. Then, the dried gas will enter the conveying pipe 211 through the intermediate pipe 212 and be conveyed into the equipment, thereby achieving the purpose of conveying and drying hydrogen chloride gas.

[0035] When hydrogen chloride gas is started, the operator activates the external high-pressure gas delivery equipment. During operation, the high-pressure gas equipment delivers the selected gas into delivery pipe 211. The gas can be compressed air or nitrogen. As the external high-pressure gas delivery equipment delivers gas into delivery pipe 211, the gas flows between conical pipe one 221 and conical pipe two 222. When the gas flows through the narrow channel in the center of conical pipe one 221 and conical pipe two 222, a high-speed, low-pressure zone is created within this narrow channel. This low-pressure zone allows the hydrogen chloride gas in drying tank 121 to be drawn into conical pipe one through intermediate pipe 212. 221 and the conical tube 222 drive the transport of hydrogen chloride gas. By changing the gas transport pressure or flow rate of the high-pressure gas transport equipment, the pressure of hydrogen chloride gas during transport can be increased in real time. Subsequently, as the gas continues to flow, it will pass through the spiral tube 213. When the gas flows through the spiral tube 213, the multiple spiral structures inside the spiral tube 213 can stabilize the turbulent flow of the gas. By pressurizing the hydrogen chloride during transport and ensuring the stability of the gas flow, the gas transport efficiency can be improved while reducing the possibility of backflow of gas into the collection equipment, which could cause pollution during transport, thus improving the transport efficiency.

[0036] Because the flow velocity and pressure of the hydrogen chloride gas entering the buffer tank 111 and the drying tank 121 are constantly changing, and the gas flow when hydrogen chloride gas flows under its own pressure into the conical pipe 221 and the conical pipe 222 and when it is drawn in through the conical pipe 221 and the conical pipe 222 is also not constant, even when the amount of gas in the buffer tank 111 and the drying tank 121 is sufficient and the gas supplied by the external equipment passes through the conical pipe 221 and the conical pipe 222, the flow velocity and pressure of the hydrogen chloride gas are not constant. Upon inhalation, the rapid flow of hydrogen chloride gas pushes the sidewall of the inclined plate 301, compressing and bending the spring. Under this pressure, the inclined plate 301 slides towards the conical tube 221 via the telescopic frame 223. At this point, the inlet size between the conical tube 221, the pressurizing component 22, and the intermediate tube 212 is at its normal size. If the gas volume and pressure in the buffer tank 111 and the drying tank 121 decrease, the inclined plate 301 will not be subjected to excessive pressure. When there is excessive pushing during the flow of multiple gases, the bending spring on the side wall of the inclined plate 301 will push the inclined plate 301 to reset under the action of its own elastic potential energy release. When the inclined plate 301 resets, it will drive the second conical tube 222 to slide through the telescopic frame 223. At this time, the inlet between the second conical tube 222, the first conical tube 221 and the intermediate tube 212 will be enlarged. By enlarging the inlet, the flow area of ​​the gas entering the first conical tube 221 and the second conical tube 222 can be adjusted. At the same time, it can also ensure timely changes when hydrogen chloride gas is drawn in, and thus timely adjustment when hydrogen chloride gas changes. This reduces the situation where hydrogen chloride enters the first conical tube 221 and the second conical tube 222 and causes flow separation and stalling when adjusting the delivery pressure in real time due to the decrease in the amount of hydrogen chloride gas in the tank. This allows the gas to be smoothly drawn into the first conical tube 221 and the second conical tube 222, while improving the stability of the gas delivery.

[0037] When hydrogen chloride gas flows through concentrated sulfuric acid, the concentrated sulfuric acid absorbs the water vapor in the hydrogen chloride. At this time, the hydrogen chloride gas, upon contact with the concentrated sulfuric acid, generates a rapid upward gas flow within the sulfuric acid. As the hydrogen chloride gas flows between the two S-plates 312, a portion of the gas flowing between the two S-plates 312 passes between the two curved plates 321. Because the sidewalls of the curved plates 321 have several conical holes, when some gas flows through these holes, the curved plates 321 and the conical holes on their sidewalls capture any residual liquid hydrogen chloride or sulfuric acid mist within the gas, preventing it from escaping. The gas can condense between the curved plate 321 and the S plate 312 and flow back into the drying tank 121 along the inclined surface at the bottom of the intermediate tube 212. At the same time, the shaking of the S plate 312 can dynamically capture the gas. By capturing the liquid contained in the gas, the corrosion caused by these corrosive mist particles entering between the conical tube 221 and the conical tube 222 can be reduced, resulting in pitting on the surface. It can also reduce the number of mist particles entering the collection device with the gas, thereby improving the gas drying intensity and the uniformity and intensity of gas delivery when it is drawn in.

[0038] When some of the flowing gas is obstructed by the conical nozzle 222 and flows back, the backflowing gas is guided by the arc surface of the semicircular plate 313 to flow obliquely upwards, thus preventing backflow. Because conical grooves are formed between the semicircular plates 313, when the backflowing gas flows through the arc surface of the semicircular plates 313, a small portion of the gas will flow through the conical grooves between the semicircular plates 313 towards the curved plate 321. At this time, the flowing gas can reverse the flow of gas through the conical holes on the side wall of the curved plate 321. The reverse flow and impact on the conical holes of the curved plate 321 can reduce the situation where the conical holes are blocked by water film due to long-term capture of water mist particles in the gas. This improves the stability of water mist particle capture and reduces the flow obstruction of some liquid at the side wall of the curved plate 321 caused by the water film blocking the conical holes. This further reduces the backflow of gas when passing through the curved plate 321 and enhances the continuity and stability of gas flow.

[0039] When gas is transported through the intermediate pipe 212, the gas flow passes between multiple S-plates 312. When gas flows between two S-plates 312, the gas between each pair of S-plates 312 is guided by the curved plate 322 to flow obliquely upwards. At the same time, the gas that is blocked by the conical pipe 222 and causes backflow will also flow obliquely upwards under the guidance of the arc of the semi-circular plate 313. Simultaneously, the multiple S-plates 312 will cause the S-plates 312 and the curved plate 322 to sway slightly during the flow. When gas flows between two S-plates 312, the swaying of the S-plates 312 and the guidance of the curved plate 322 enable the gas to flow smoothly and efficiently. Regardless of whether the inlet between conical tube 1 221 and conical tube 222 is expanded or contracted, it ensures that gas can be adsorbed into conical tube 1 221 and conical tube 222 through the inlet between conical tube 1 221 and conical tube 222. This reduces the situation where some gas flowing through intermediate tube 212 is blocked by conical tube 222 when the inlet size between conical tube 1 221 and conical tube 222 is in a normal state, causing some gas to backflow before entering conical tube 1 221 and conical tube 222 in intermediate tube 212. This further ensures stable gas delivery and improves the delivery efficiency and continuity of gas delivery.
