Description

Technical Field

[0001] This utility model relates to the field of liquid supply equipment technology, specifically to a coal tar hydrogenation liquid sulfur injection device. Background Technology

[0002] In coal tar hydrogenation processes, the injection of liquid sulfur is a crucial step. It not only affects the efficiency of the hydrogenation reaction but also directly relates to the quality of the final product and the stability and safety of the entire process. However, existing liquid sulfur injection devices suffer from a series of problems that urgently require improvement and optimization.

[0003] Existing liquid sulfur injection units have shortcomings in precisely controlling the amount of liquid sulfur injected. Coal tar hydrogenation processes have strict requirements on the amount of liquid sulfur injected; too much or too little will affect the hydrogenation reaction. However, existing units often lack effective metering and control systems, making it difficult to achieve precise control of the liquid sulfur injection amount. This may lead to unstable product quality and even fail to meet actual customer needs.

[0004] Therefore, in response to the problems existing in the current technology, there is an urgent need for an injection device that can stably, continuously, and accurately transport liquid sulfur. This device should possess the following characteristics: first, it should be able to achieve a stable and continuous transport of liquid sulfur, avoiding problems such as blockage and poor flow; second, it should be able to accurately control the injection volume of liquid sulfur, ensuring the effectiveness of the hydrogenation reaction and product quality; and third, it should be easy to maintain and repair, reducing equipment maintenance costs and environmental risks. Utility Model Content

[0005] In view of this, the present invention provides a coal tar hydrogenation liquid sulfur injection device. The present invention provides a stable and continuous water supply to the stirring drum through a water supply unit, and when one water supply unit fails to work properly, another water supply unit can be used to work, thereby enabling the liquid sulfur injection operation to operate normally.

[0006] To solve the above technical problems, this utility model provides a coal tar hydrogenation liquid sulfur injection device, including an output pipe connected to a storage tank, through which liquid sulfur in the storage tank can be discharged. Multiple water supply units are connected to the end of the output pipe, and each water supply unit is connected to the feed pipe of a stirring drum. The stirring drum is used to mix liquid sulfur and coal tar, and the water supply units are used to supply liquid to the stirring drum.

[0007] The water supply unit includes a water supply pipe connected to the output pipe, through which liquid sulfur in the output pipe can flow into the water supply pipe. The end of the water supply pipe is connected to the inlet pipe, through which liquid sulfur in the water supply pipe can be input into the mixing drum. The water supply pipe is sequentially equipped with a switch valve for water flow interruption, a pressure stabilizing valve for stabilizing water pressure, a pressure regulating valve for adjusting the water flow in the pipeline, and a pressure gauge for detecting water pressure.

[0008] The water supply pipe is also equipped with a return pipe. One end of the return pipe is located between the pressure reducing valve and the switching valve, and the other end of the return pipe is connected to the storage tank. The return pipe can return the excess liquid sulfur in the water supply pipe into the storage tank.

[0009] The water supply pipe consists of a first water supply pipe, a second water supply pipe, and a third water supply pipe. The switch valve and return pipe are installed on the first water supply pipe, and the pressure stabilizing valve, the pressure regulating valve, and the pressure gauge are installed on the second water supply pipe. The third water supply pipe is connected to the feed pipe. The two ends of the second water supply pipe are detachably fixed between the first water supply pipe and the third water supply pipe, which facilitates the maintenance of the pressure stabilizing valve, the pressure regulating valve, and the pressure gauge.

[0010] The second water supply pipe is connected to the first or third water supply pipe at both ends via flanges, allowing for quick assembly and disassembly of the second water supply pipe.

[0011] Both the third water supply pipe and the return pipe are equipped with check valves to prevent liquid sulfur in the pipes from dripping onto the ground after the second water supply pipe is disassembled.

[0012] Two sets of water supply units are installed between the output pipe and the inlet pipe.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. Stable and continuous liquid sulfur transportation: Through a carefully designed water supply unit, this invention ensures a stable and continuous transportation of liquid sulfur from the storage tank to the mixing drum. The on / off valve, pressure stabilizing valve, pressure regulating valve, and pressure gauge configured on the water supply pipe together constitute a complete control system, effectively avoiding blockage and poor flow of liquid sulfur during transportation, thereby ensuring the continuity and stability of the process.

[0015] 2. Precise Control of Liquid Sulfur Injection: This invention achieves precise control of the liquid sulfur injection volume through precise regulation of the water supply unit. This not only meets the stringent requirements of the coal tar hydrogenation process for liquid sulfur injection volume but also significantly improves the quality stability and consistency of the final product, enabling the product to better meet customer needs.

[0016] 3. Easy Maintenance and Upkeep: The second water supply pipe in the water supply unit adopts a detachable design and is connected to the first and third water supply pipes via flanges. This design greatly simplifies the maintenance and upkeep of the equipment. Maintenance personnel can quickly disassemble and assemble the second water supply pipe to inspect, clean, or replace key components such as pressure regulating valves, pressure gauges, etc., thereby reducing equipment maintenance costs and minimizing the risk of production interruptions due to equipment failure.

[0017] 4. Reduced Environmental Risks: This invention incorporates one-way valves on both the third water supply pipe and the return pipe. This design effectively prevents liquid sulfur from dripping onto the ground after the second water supply pipe is disassembled, thus avoiding environmental pollution and safety hazards. This not only meets environmental protection requirements but also helps enhance the company's social image and reputation.

[0018] 5. Improved Production Efficiency: Because this invention can stably, continuously, and precisely deliver liquid sulfur, it can significantly improve the production efficiency of the coal tar hydrogenation process. At the same time, the easy-to-maintain and servicing design reduces production downtime caused by equipment failure, further improving overall production efficiency and economic benefits.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0027] A coal tar hydrogenation liquid sulfur injection device, such as Figure 1 As shown: It includes an output pipe 101 connected to the storage tank 100. The output pipe 101 is connected to the feed pipe 301 of the mixing drum through the water supply unit 200. The liquid sulfur in the storage tank 100 can enter the water supply unit 200 through the output pipe 101. The water supply unit 200 can input the liquid sulfur into the mixing drum 300 through the feed pipe 301. The mixing drum 300 can stir and mix the liquid sulfur and coal tar.

[0028] Specifically, the water supply unit 200 includes a water supply pipe 210 connecting the output pipe 101 and the inlet pipe 301, such as... Figure 1 As shown: A switch valve 220 and a pressure regulating valve 222 are sequentially installed on the water supply pipe 210 from the water delivery pipe to the water inlet pipe. The switch valve 220 is used to control the flow of water in the water supply pipe 210, and the pressure regulating valve 222 is used to adjust the water pressure in the water supply pipe 210. That is, when the switch valve 220 is opened, liquid sulfur can flow through the water supply pipe 210, and when the pressure regulating valve 222 is used, the pressure regulating valve 222 can adjust the water flow in the water supply pipe 210, so as to avoid excessive liquid sulfur entering the mixing tank.

[0029] Furthermore, the water supply unit 200 also includes a pressure regulating valve 221 installed on the water supply pipe 210. The pressure regulating valve 221 is located between the switching valve 220 and the pressure regulating valve 222. The pressure regulating valve 221 can reduce and stabilize the water pressure in the water supply pipe 210, thereby preventing liquid sulfur in the water supply pipe 210 from gushing towards the pressure regulating valve 222.

[0030] Furthermore, the water supply unit 200 is also equipped with a pressure gauge 223, which is located between the pressure regulating valve 222 and the water inlet pipe. The pressure gauge 223 is used to detect the water pressure in the water supply pipe 210 and display it digitally, so that the water pressure in the water supply pipe 210 can be clearly understood through the pressure gauge 223.

[0031] The water supply unit 200 also includes a return pipe. One end of the return pipe is located between the pressure reducing valve and the switching valve 220, and the other end of the return pipe is connected to the storage tank 100. That is, if the water flow in the water supply pipe 210 is greater than the preset water flow of the pressure regulating valve 222, the excess liquid sulfur can flow back into the storage tank 100 through the return pipe.

[0032] It is worth mentioning that the water supply pipe 210 consists of a first water supply pipe 211, a second water supply pipe 212, and a third water supply pipe 213. The switch valve 220 and the return pipe are installed on the first water supply pipe 211. The pressure stabilizing valve 221, the pressure regulating valve 222, and the pressure gauge 223 are installed on the second water supply pipe 212. The third water supply pipe 213 is connected to the feed pipe 301. The two ends of the second water supply pipe 212 are detachably fixed between the first water supply pipe 211 and the third water supply pipe 213. That is, if the digital display value of the pressure gauge 223 does not match the preset value, it indicates that the detection effect of the pressure gauge 223 is damaged or the pressure regulating valve 222 is damaged. The second water supply pipe 212 can be removed from between the first water supply pipe 211 and the third water supply pipe 213, so that the pressure stabilizing valve 221, the pressure regulating valve 222, and the pressure gauge 223 can be maintained.

[0033] Specifically, the two ends of the second water supply pipe 212 are connected to the first water supply pipe 211 or the third water supply pipe 213 through flanges, which allows for quick disassembly and assembly of the second water supply pipe 212, thus effectively improving the maintenance efficiency of the water supply unit 200.

[0034] Furthermore, the water supply unit 200 also includes a one-way valve installed on the third water supply pipe 213 and the return pipe, so that the liquid sulfur remaining in the third water supply pipe 213 and the return pipe will not fall to the ground after the second water supply pipe 212 is disassembled.

[0035] Two sets of water supply units 200 are provided between the output pipe 101 and the inlet pipe. When one water supply unit 200 is being maintained, the other water supply unit 200 can be used to work, so that the water supply unit 200 can be maintained without stopping the machine, thereby indirectly improving the working efficiency of liquid sulfur injection.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
