Description

Technical Field

[0001] This utility model relates to the field of desulfurization technology, and in particular to an integrated device for intelligent monitoring and jet mass transfer synergistic enhancement of desulfurization. Background Technology

[0002] Currently, in the field of desulfurization reactions involving gas-liquid reactions, desulfurization devices often require uniform gas-liquid mixing, low clogging rates, and monitorability. For example, traditional hydrogen sulfide absorption devices atomize polyacid desulfurization liquid using multiple atomizing nozzles in the desulfurization tower, allowing the polyacid desulfurization liquid to come into countercurrent contact with hydrogen sulfide gas to achieve hydrogen sulfide removal. However, during the atomization process, the polyacid desulfurization liquid is not uniformly atomized, resulting in insufficient gas-liquid contact time and reduced desulfurization efficiency. Therefore, a high degree of uniformity in the mixing of hydrogen sulfide gas and polyacid desulfurization liquid is required. Furthermore, during the spraying of the polyacid desulfurization liquid through the atomizing nozzles, some solid substances, such as sulfur, are generated. These solid substances accumulate in the atomizing nozzles, causing blockages, affecting system operation, and increasing operating and maintenance costs. More importantly, the lack of effective monitoring of the desulfurization conditions of polyacid desulfurization liquid makes it difficult to grasp key parameters in the desulfurization process in real time, such as the temperature, pH and hydrogen sulfide concentration of the polyacid desulfurization liquid. This results in the inability to adjust the desulfurization process in a timely manner, affecting the desulfurization effect and the stability of the system, as follows.

[0003] A search revealed patent CN102872713B, which discloses a desulfurization and regeneration device for removing H2S using a gas delivery pipeline. The device includes: a gas delivery pipeline, which is substantially horizontal, with a diameter greater than or equal to 0.3 m and a length-to-diameter ratio greater than or equal to 10; a liquid outlet on the gas delivery pipeline; a gas outlet at the end of the gas delivery pipeline; a regeneration tank below the gas delivery pipeline, containing an aeration device; and multiple atomizing nozzles for spraying desulfurization liquid or desulfurization slurry, arranged sequentially along the gas delivery direction within the gas delivery pipeline. This invention, using a gas delivery pipeline as the site for H2S removal, eliminates the need for additional desulfurization equipment compared to existing desulfurization towers or other desulfurization reactors, effectively reducing construction costs.

[0004] A search revealed a patent with publication number CN209584129U, which discloses a regeneration device for rich desulfurization solution in coal gas desulfurization. The desulfurization tower has a spray device inside its cavity, and inlets and outlets are located on its side and bottom, respectively. The regeneration device includes a regeneration tank, with the outlet extending into it via a circulation pipe. The regeneration tank is also connected to an oxygen inlet mechanism. A desulfurization lean solution outlet is located on the side of the regeneration tank, connected to a level regulator. The level regulator is connected to the inlet via a return pipe. A sulfur foam outlet is located on the side of the regeneration tank. This invention improves the uniformity of gas-liquid distribution, alleviates system blockage, increases reaction efficiency, and requires low investment.

[0005] As mentioned above, jet mass transfer mixing devices offer advantages such as high gas-liquid mass transfer efficiency, good mixing effect, low clogging rate, and the ability to monitor liquid conditions. However, their effectiveness in desulfurization is limited when used alone. While polyacid desulfurization solutions can effectively remove hydrogen sulfide, uneven gas-liquid mixing leads to low gas-liquid mass transfer efficiency, affecting the desulfurization effect. Therefore, combining jet mass transfer mixing devices with polyacid desulfurization solutions under optimal desulfurization conditions to improve gas-liquid mass transfer efficiency and desulfurization rate while reducing equipment clogging has become an urgent problem to be solved.

[0030] In the specific implementation process, unused, clean polyacid desulfurization liquid 3 is placed in desulfurization reactor 19. First, the jet mass transfer mixing pump 6 is powered on and adjusted to a suitable flow rate, specifically 15 m³ / h. The hydrogen sulfide gas flow rate is also adjusted to a suitable range of 20-40 m³ / h, specifically 30 m³ / h. The jet mass transfer mixer 14 is equipped with nozzles and a mass transfer chamber, such as... Figure 2 As shown, the polyacid desulfurization liquid 3 is sprayed out through the nozzle in the form of a high-speed jet, forming a negative pressure in the mass transfer mixing chamber, and drawing in hydrogen sulfide gas from the hydrogen sulfide gas supply pipe 17, so that the hydrogen sulfide gas and the polyacid desulfurization liquid 3 are fully mixed. At this time, the monitoring mechanism located in the pump outlet pipe 12, the hydrogen sulfide gas supply pipe 17, and the gas outlet pipe 21 will collect various parameters in real time during the desulfurization process and transmit them to the control system. After the system is started, it begins to carry out the integrated operation of intelligent monitoring and jet mass transfer mixing to enhance the desulfurization of polyacid desulfurization liquid 3.

[0031] Among them, the third butterfly valve 7 is used to control the opening and closing of the pump suction pipe 8, the fourth butterfly valve 13 is used to control the opening and closing of the pump discharge pipe 12, and the fifth butterfly valve 15 is used to control the opening and closing of the hydrogen sulfide gas transmission pipe 17. In order to realize the application under different processes, a four-way valve 18 is provided at one end of the hydrogen sulfide gas transmission pipe 17, which can be connected to a gas pipeline for diluting hydrogen sulfide.

These sensors can collect various parameters in the desulfurization process in real time and transmit the data to the control system, thereby adjusting the desulfurization process in a timely manner and greatly improving the stability of the system.

[0033] It should also be noted that the jet mass mixing pump 6 has two pump suction pipes 8 and two pump discharge pipes 12. One pipe is used to allow the polyacid desulfurization liquid 3 to enter the jet mass mixing pump 6 from the desulfurization reactor 19, and the other pipe is used to transport the polyacid desulfurization liquid 3 in the jet mass mixing pump 6 back to the desulfurization reactor 19. The location of the two pipes is determined according to the specific working conditions, and no specific limitation is made here, as long as the above functions can be achieved.

[0034] Furthermore, since hydrogen sulfide gas can cause serious damage to the human respiratory system, the sealing performance of the device is of paramount importance. Specifically, to ensure the sealing of all connecting pipes, the desulfurization reactor 19 is connected to the pump suction pipe 8 via flanges, all butterfly valves are connected via threads or flanges, and the jet mass mixing pump 6, pump suction pipe 8, and pump discharge pipe 12 are connected via flanges. To further improve sealing, sealing tape or gaskets are installed at all connections, and airtightness testing is performed.

[0035] Among them, the valves installed on the pump suction pipe 8 and the pump discharge pipe 12, as well as the multiple instruments installed on the pump discharge pipe 12, are all made of any material such as SS304 stainless steel, as long as they can effectively achieve the above functions and ensure sealing. For example, the material can also be SS316 stainless steel.

[0038] Among them, the jet mass mixer 14 and the demister 20 can be made of any suitable material such as SS316 stainless steel;

[0039] Among them, the threaded connection is a sealing thread. For example, there are sealing threads at the connection between the external pipes of the inlet pipe 1 and the outlet pipe 4, and at the connection between the instruments of the monitoring system and the outlet pipe 12 of the pump. In addition, it should be noted that the location of the thread is not limited to the locations listed above. The staff can set the thread at any required location based on the actual situation. For example, the four-way 18 at the upper end of the hydrogen sulfide gas pipeline 17 can be threaded to achieve a sealed connection with other components. Of course, sealing tape, sealing gaskets, flanges and other components can also be installed.

[0040] Among them, sealing gaskets are provided at the connection between the pump suction pipe 8 and the pump discharge pipe 12 and the desulfurization reactor 19, at the two ends of the jet mass mixing pump 6, and at the connection between the hydrogen sulfide gas pipeline 17 and the pump discharge pipe 12.

Then, the hydrogen sulfide mixed gas and the polyacid desulfurization liquid 3 are sprayed into the desulfurization reactor 19 through the jet mass mixer 14. The integration of absorption, jet mass mixing, and intelligent monitoring of the polyacid desulfurization liquid 3 improves the desulfurization effect, reduces the desulfurization cost, increases the stability of the system, and has high practicality.
