Description

Technical Field

[0001] The utility model relates to sulfur particle recovery and tail gas treatment, in particular to a sulfur particle recovery and tail gas treatment device in a sulfur granulation process. Background Art

[0002] The petrochemical industry uses petroleum and natural gas as raw materials, producing a variety of petrochemical products through physical, chemical, and mechanical processing. It touches every sector of the national economy. Currently, over 40 million tons of sulfur are extracted annually as a liquid byproduct of petroleum and natural gas. If sulfur produced through desulfurization in industries such as coal chemical, smelting, and power generation is included, annual production far exceeds 40 million tons. The industry is diverse across industries, processes, scales, and applications. However, due to sulfur's unique physical and chemical properties, the vast majority of liquid sulfur must be converted into uniform, solid granules for safe, reliable, and environmentally friendly transportation, storage, and use. Granulated sulfur granules offer advantages such as stable characteristics and ease of transportation, making sulfur granulation a standard option for the sulfur production industry. However, due to temperature-induced phase transitions during the sulfur granulation process, a small amount of sulfur granules inevitably transform into vapor, which then enters exhaust gases and impacts the atmospheric environment.

[0003] Therefore, it is imperative to treat sulfur tail gas. Most domestic sulfur granulation processes use a granulation and drying integrated process. After treatment, the dry granulation tail gas discharged will inevitably contain a large amount of sulfur dust, which is higher than the maximum dust particulate matter limit of 20mg / m3 in GB31570-2015. 3 The permissible emission standards cannot meet the increasingly stringent environmental protection requirements. If the exhaust site is not handled properly, the odor and scattered particles will be more obvious, and in serious cases it will even affect the normal work and life of surrounding residents.

[0004] In view of this, it is necessary to provide a sulfur particle recovery and tail gas treatment device in the sulfur granulation process to solve or overcome the above technical problems. Utility Model Content

[0038] The sulfur granule recovery and tail gas treatment device in the sulfur granulation process has a system recovery method as follows:

[0039] S01, particle recovery: the pressurized sulfur tail gas is tangentially fed into the rotary jet oscillation absorber 2 from the tangential inlet 203 to generate a rotating turbulent flow field; the pressurized water flow is fed into the rotary jet oscillation absorber 2 from the liquid inlets 205 on both sides to generate a jet field in the rotary jet oscillation absorber 2; the rotating turbulent flow field and the jet flow field interact with each other, thereby increasing the gas-liquid contact area, so that the sulfur particles and droplets combine, settle down by gravity, and are discharged from the bottom flow outlet 207 into the sedimentation tank 4, completing the recovery of sulfur particles in the sulfur granulation process;

[0040] S02, demisting: the gas discharged in S01 is transported from the gas outlet 201 to the next-stage baffle and coalescing device 7 to complete the demisting of the sulfur particles in the sulfur granulation process;

[0041] S03, discharge and cleaning: the tail gas after demisting is discharged from the exhaust device 9, and the liquid delivery device 8 cleans the deflection and coalescing device 7 through the backwash pipe.

[0042] The working principle of the sulfur particle recovery and tail gas treatment device in the sulfur granulation process in the above technical solution is explained with reference to the figure:

[0043] The sulfur tail gas to be treated enters the rotary jet oscillation absorber 2 through the air supply device 3, and the water flow is input into the rotary jet oscillation absorber 2 through the liquid supply device 8. At this time, the sulfur tail gas to be treated forms a rotating turbulent flow field in the rotary jet oscillation absorber 2, and the sulfur particles are thrown to the surroundings by centrifugal force and flow out from the bottom flow port of the rotary jet oscillation absorber 2; the water flow forms a jet flow field in the rotary jet oscillation absorber 2, and the rotating turbulent flow field and the jet flow field cut and collide, breaking the jet into droplets, increasing the gas-liquid contact area, and the sulfur particles in the sulfur tail gas combine with the droplets, settle down under the action of gravity, and flow out from the bottom flow port.

[0044] The purified gas is discharged from the top gas outlet 201 of the rotary spray oscillation absorber 2 and enters the deflection and coalescence device 7. The deflection and coalescence device 7 can remove the droplets entrained in the gas to obtain purified gas, and guide the purified gas to the exhaust device 9 for discharge.

[0045] Furthermore, a drainage pipe 6 is provided at the bottom of the rotary jet oscillation absorber 2, the baffle coalescing device 7, and the exhaust device 9. The drainage pipe 6 is used to collect sulfur particles and droplets and transport them to the sedimentation tank 4. A backwash pipe 5 is also provided at the bottom of the baffle coalescing device 7. A liquid supply pipe is provided at the lower part of the rotary jet oscillation absorber 1. It is worth noting that the backwash pipe 5 and the liquid supply pipe are connected to the liquid supply device 8 through the same pipe. The backwash pipe 5 is used to flush the baffle coalescing device 7 after the baffle coalescing device 7 stops operating. It should be noted that during the particle recovery process, a small amount of droplets and particulate matter accumulates in the baffle coalescing device 7 and the exhaust device 9. If these droplets and particulate matter are not removed, the operating efficiency of the device will be affected. Therefore, a backwash pipe 5 is installed at the bottom of the baffle coalescing device 7 through a threaded or flanged connection. Each of the liquid inlets 205 is connected in parallel to the liquid supply pipe and then to the liquid supply device 8. A drainage pipe 6 is installed at the bottom of the baffle coalescing device 5 and the exhaust device 9 through a threaded or flanged connection.

[0046] As a specific embodiment of the rotary spray oscillation absorber 2, see Figure 1 、 2 As shown, the rotary jet oscillation absorber 2 includes a jacket 204 and a cylinder 202. The jacket 204 is sleeved on the outside of the cylinder 202, and a cavity structure capable of accommodating water flow is formed between the inner surface of the jacket 204 and the outer surface of the cylinder 202. The outer circumferential surface of the cylinder 202 is provided with a spray hole 206 capable of accommodating water flow to enter the interior of the cylinder 202. It should be noted that the sulfur tail gas enters the cylinder 202 structure along the tangential direction of the rotary jet oscillation absorber 2. The provision of the spray hole 206 enables the water jet 206 to enter the cylinder 202 of the rotary jet oscillation absorber 2 and form a spray flow field.

[0047] The utility model discloses a method for recovering sulfur particles and treating tail gas in a sulfur granulation process, comprising the following steps:

[0048] S01, particle recovery: the pressurized sulfur tail gas is input into the rotary jet oscillation absorber 2 to generate a rotating turbulent flow field; the pressurized water flow is input into the rotary jet oscillation absorber 2 to generate a jet field in the rotary jet oscillation absorber 2; the rotating turbulent flow field and the jet flow field are mutually interfered with each other, thereby increasing the gas-liquid contact area, so that the sulfur particles and droplets are combined, settled by gravity, and discharged into the sedimentation tank 4, completing the recovery of sulfur particles in the sulfur granulation process;

[0049] S02, demisting: the gas discharged in S01 is transported to the next-stage baffle coalescing device 7 to complete the demisting of sulfur particles in the sulfur granulation process;

[0050] S03, discharge and cleaning: the tail gas after demisting is discharged from the exhaust device 9, and the liquid delivery device 8 cleans the deflection and coalescing device 7 through the backwash pipe 5.

[0051] In more detail, in the above step S01, the sulfur tail gas to be treated enters the rotary jet oscillation absorber 2 at high speed along the tangential inlet 203 of the rotary jet oscillation absorber. The high speed tangential here means that the sulfur tail gas to be treated enters the rotary jet oscillation absorber 2 at a high gas speed along the tangential direction of the outer wall of the rotary jet oscillation absorber 2, generating a gas phase turbulent field with huge centrifugal force to cut the injected water flow to form droplets, which can increase the gas-liquid contact area and improve the purification efficiency and accuracy.

[0052] As a relatively preferred embodiment of the present invention, refer to Figures 1 to 2 , provides a sulfur particle recovery and tail gas treatment device in the sulfur granulation process, including an air supply device 3 and a liquid supply device 8, the air supply device 3 and the liquid supply device 8 are connected to a rotary jet oscillation absorption device 1, the rotary jet oscillation absorption device 1 includes two parallel rotary jet oscillation absorbers 2, the rotary jet oscillation absorber 2 is provided with a cylindrical barrel 202 and a jacket arranged on the barrel, the cylindrical barrel 202 is provided with a spray hole, the air outlet 201 of the rotary jet oscillation absorber 2 is connected to a deflection and coalescing device 7, the deflection and coalescing device 7 is connected to an exhaust device 9, a drainage pipe 6 is provided at the bottom of the deflection and coalescing device 7 and the exhaust device 9, and a backwash pipe 5 is also provided at the bottom of the deflection and coalescing device 7.

[0053] The specific working process is as follows: first, the air supply device 3 pressurizes the sulfur tail gas to be treated and delivers it to the air inlet of the rotary jet oscillation absorber 2; the liquid supply device 8 pressurizes the water flow and delivers it to the liquid inlet 205 of the rotary jet oscillation absorber 2; the liquid inlet 205 sprays the inside of the rotary jet oscillation absorber 2 through the injection hole 206 opened on the cylindrical body 202; the sulfur tail gas entering the tangential air inlet can only be transported downward along the spiral outlet pipe; at this time, the sulfur tail gas to be treated forms a rotating turbulent flow in the rotary jet oscillation absorber 2 The field causes the sulfur particles to be thrown around by centrifugal force, and after combining with the water mist, they flow out from the bottom flow port 207 of the rotary jet oscillation absorber; the water flow forms a jet flow field in the rotary jet oscillation absorber 2, and the water is pressurized and injected into the absorber through the injection hole to naturally form a jet flow field. Due to the cutting and collision between the rotating turbulent field and the jet flow field, the jet exhaust gas is broken into droplets, increasing the gas-liquid contact area, and the sulfur particles in the sulfur exhaust gas are combined with the droplets, settled down by the action of gravity, and flow out from the bottom flow port 207. The purified gas enters from the bottom of the outlet pipe of the rotary jet oscillation absorber and is discharged from the top outlet 201 into the deflection and coalescence device 7. The deflection and coalescence device 7 can remove the droplets entrained in the gas. During use, after the gas entrained with droplets enters the channel of the corrugated deflection module, the direction of the gas flow changes with the change of the direction of the multi-fold blade plate. Due to inertia, the direction of movement of the droplets entrained in the gas is not as easy to change as the air flow. They hit the multi-fold blade plate and adhere to the surface of the plate to form a water film. The liquid film moves forward with the air flow to the turning point and is separated. After the preliminary separation, the gas enters the fiber coalescence module, and the entrained droplets are intercepted and adsorbed by the surface-modified fibers to obtain further purified gas, which is then directed to the exhaust device 9 for discharge. After the device stops running, the deflection and coalescence device 7 is backwashed.

[0054] The following is a description of two specific examples in actual production. The first example is the sulfur particles in the flue gas outlet of a sulfur granulator in a petrochemical plant, with a temperature of 90°C and a temperature of 15000m 3 / h, the sulfur dust concentration at the granulator outlet is 500mg / m 3 As mentioned above, by using the sulfur particle recovery and tail gas treatment method in the sulfur granulation process of the utility model, the sulfur dust concentration at the granulator outlet is reduced to 5mg / m 3 As another specific embodiment, the inlet gas flow rate is 80000m 3 / h, assuming the temperature is 55°C and the particle concentration is about 200 mg / m 3 After the sulfur granulation process is treated by the sulfur granule recovery and tail gas treatment method of the utility model, the concentration of the purified particulate matter is reduced to 1mg / m 3 Below, the absorption effect is greater than 99%.

[0055] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention may be subjected to various simple modifications, including combining the specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be considered as disclosed in the present invention and fall within the scope of protection of the present invention.

[0056] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as disclosed by the present invention.
