[0002] The sulfuric acid plant uses sulfur as the main raw material. It is necessary to melt solid sulfur into liquid sulfur or directly purchase liquid sulfur for actual needs. The solid sulfur melting process and the liquid sulfur storage process will produce sublimated sulfur, water vapor, hydrogen sulfide and other gases that pollute the environment. At present, there is no good tail gas absorption device for the treatment of tail gas from solid sulfur melting and liquid sulfur storage, and further related research and development work is needed.

[0003] With the improvement of environmental protection management requirements, sulfuric acid plants have to abandon solid sulfur as a chemical raw material in order to treat liquid sulfur tail gas, and switch to directly purchasing liquid sulfur for sulfuric acid production.

DETAILED DESCRIPTION

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] like Figure 1-Figure 10 As shown, a tail gas absorption device for solid sulfur melting and liquid sulfur storage of the present invention comprises: a device base 1, a separation component 2, a condensation component 3 and an absorption tower component 4 are sequentially installed on the top of the device base 1 from one end to the other end, the separation component 2 comprises a cyclone separator 21 fixed at one end of the top of the device base 1, an air inlet pipe of the cyclone separator 21 is docked with a contraction port 22, and the air inlet pipe is docked with a knocking component 5 installed on the top of the device base 1, and the knocking component 5 is driven by a driving component 6 installed on the top of the device base 1 to knock the air inlet pipe, and the condensation component 3 comprises A condenser 31 is installed on the top of the device base 1, a powerful fan 32 is installed at one end of the condenser 31, and the outlet pipe of the cyclone separator 21 is connected to the inlet pipe of the condenser 31. The absorption tower assembly 4 includes a treatment tower 41 installed on the top of the device base 1, the treatment tower 41 is connected to the outlet pipe of the condenser 31, and a liquid tank 42 is provided on one side of the treatment tower 41, a pump 43 is installed on the top of the liquid tank 42, and the output pipe of the pump 43 is connected to the nozzle 46 inside the treatment tower 41, and the pump 43 is used to spray the weak alkaline liquid and hydrogen peroxide loaded in the liquid tank 42 into the nozzle 46.

[0024] As described above, by designing the separation component 2, the condensation component 3 and the absorption tower component 4, when the tail gas treatment of solid sulfur melting and liquid sulfur storage is carried out, the tail gas enters the cyclone separator 21 through the air inlet pipe docking contraction port 22, and the solid particles in the tail gas are removed by the cyclone separation action, that is, the heavier sublimated sulfur particles are separated from the air flow, and the cleaned tail gas enters the condensation component 3, and the water vapor is condensed into liquid water and discharged by lowering the temperature or increasing the humidity, thereby removing the water vapor and acidic condensed water, and then the gas is introduced into the treatment tower 41, and the pump 43 is started. First, a weak alkaline liquid is sprayed out through the nozzle 46, and the hydrogen sulfide in the gas reacts with the hydroxide ions in the solution to generate sodium sulfide and water. After a period of time, hydrogen peroxide is sprayed out again, and the hydrogen peroxide reacts with the sodium sulfide to generate sulfur and water. At this time, the sulfur exists in the solution in the form of solid particles. Finally, the sulfur particles in the solution can be separated by filtering and dried to obtain a pure sulfur product, and the aqueous solution is sent to the company's sewage station for further treatment of its PH, COD and other indicators to achieve standard discharge. The sulfur is sent to the sulfur melting tank for repeated use.

[0025] The knocking assembly 5 includes a cylinder 51 fixed on the top of the device seat 1, and the cylinder 51 is passed through by a knocking rod 52 to form a sliding connection, and a knocking hammer 53 in contact with the air inlet pipe of the cyclone separator 21 is fixed at one end of the knocking rod 52, and the knocking hammer 53 is connected to the cylinder 51 by a spring A54 sleeved on the outside of the knocking rod 52; The condensing assembly 3 includes a vertical plate 1 61 and a vertical plate 2 62 fixed on the top of the device base 1. The vertical plate 2 62 is located at the air inlet of the powerful fan 32, and a fan blade 63 is rotatably installed on one side. A large gear 68 and a small gear 64 that mesh with each other are rotatably installed on the vertical plate 2 62. The small gear 64 and the fan blade 63 shafts are both connected to a pulley 65, and a belt 66 is connected between the connected pulleys 65. The large gear 68 shaft is connected to a half gear 67, and the half gear 67 is meshed with a tooth path, and the tooth path is set at the top position of the knocking rod 52.

[0026] By designing the knocking component 5 and the condensation component 3, since the air inlet pipe of the cyclone separator 21 is designed with a contraction port 22, the speed of the gas increases after entering the air inlet pipe, and the sublimated sulfur particles therein are easily adsorbed on the tube wall to cause blockage. Therefore, when the condenser 31 is working, the powerful fan 32 will also be started to blow air to the condenser 31 to enhance condensation. The wind passes through the fan blades 63, and the wind force drives the fan blades 63 to rotate. The small gear 64 rotates through the transmission action of the pulley 65 and the belt 66. The rotation of the small gear 64 also drives the rotation of the large gear 68 through the meshing relationship. A half gear 67 is connected to the rotating shaft of the large gear 68, and the half gear 67 is meshed with the tooth track set at the top of the knocking rod 52. As the large gear 68 rotates, the half gear 67 periodically contacts the tooth track and pushes the knocking rod 52 to move forward and backward. During this process, the knocking rod 52 passes through the cylinder 51 to form a sliding connection and maintains a certain elasticity under the action of the spring A54. When the half gear 67 pushes the knocking rod 52 to move backward, the spring A54 is compressed. When the half gear 67 separates from the tooth track, the spring A54 releases energy, pushing the knocking rod 52 to quickly reset, driving the knocking hammer 53 to knock the air intake pipe of the cyclone separator 21, effectively preventing the accumulation and blockage of sublimated sulfur particles on the pipe wall, and making full use of the wind resources generated during the condensation process to achieve effective energy utilization. At the same time, the linkage design of the knocking component 5 and the condensation component 3 also improves the automation level and operation efficiency of the entire exhaust gas absorption device.

[0027] A locking assembly 7 is provided on the vertical plate 61, including an arc plate 72 that is in close contact with the rotating shaft of the fan blade 63, a square rod 73 is fixed at the bottom of the arc plate 72, the bottom of the square rod 73 slides on the top of the cylinder rod 75, the bottom of the square rod 73 and the internal slideway of the cylinder rod 75 are connected to the spring B74, the cylinder rod 75 is fixed on the vertical plate 61 and is located on one side of the fan blade 63, two electromagnets 71 are fixed on the side wall of the vertical plate 61 on both sides of the rotating shaft of the fan blade 63, and the electromagnets 71 can attract the metal sheets at both ends of the arc plate 72 after being energized, and a flow sensor 28 is installed on the air inlet pipe of the cyclone separator 21, and the flow sensor 28 is electrically connected to the electromagnet 71; The contact surface between the arc plate 72 and the rotating shaft of the fan blade 63 is designed to be anti-slip.

[0028] When the exhaust gas begins to flow into the cyclone separator 21, the flow sensor 28 will monitor the gas flow in the intake pipe in real time. When the flow is large, the sublimated sulfur particles are carried by the airflow and smoothly enter the cyclone separator for separation. Therefore, there is no need to knock the component 5 to work at this time. The flow sensor 28 converts the monitored data into an electrical signal and transmits it to the electromagnet 71. When the electromagnet 71 receives the electrical signal from the flow sensor 28 and determines that the exhaust gas flow is within the normal range, it will be energized to generate magnetism and attract the metal sheets at both ends of the arc plate 72. Since the contact surface between the arc plate 72 and the shaft of the fan blade 63 is designed to be anti-slip, when the arc plate 72 is attracted by the electromagnet 71, it will fit tightly on the shaft of the fan blade 63, thereby preventing the fan blade 63 from rotating. The static state of the blade 63 further means that the transmission parts such as the small gear 64, the large gear 68 and the half gear 67 stop working, so the knocking rod 52 and the knocking hammer 53 will not perform the knocking action. In this way, when the exhaust gas flow is normal and there is no need to knock to prevent blockage, the locking component 7 can automatically lock the rotation of the blade 63, thereby avoiding unnecessary work of the knocking component 5, saving energy and extending the service life of the equipment. When the exhaust gas flow is reduced to a certain extent, or when the knocking component 5 needs to be started for other reasons, the flow sensor 28 will detect this change and send a corresponding electrical signal to the electromagnet 71. After the electromagnet 71 is powered off, it loses its magnetism, and the arc plate 72 is reset under the action of the spring B74, and no longer fits the rotating shaft of the blade 63. At this time, the fan blades 63 can rotate freely with the wind, thereby driving the entire knocking assembly 5 to start working and knock on the air intake pipe to prevent blockage. Therefore, by designing the locking assembly 7 and combining it with the flow sensor 28, we have achieved automatic control of the working state of the knocking assembly 5 according to the exhaust gas flow during ventilation, which not only ensures the efficiency of exhaust gas treatment but also improves the intelligence level of the equipment.

[0029] The bottom outlet of the cyclone separator 21 is connected to the hollow box 23, and two inclined plates 25 are installed on both sides of the hollow box 23. A collecting box 24 is inserted into the opening on one side of the hollow box 23. The collecting box 24 is below the inclined plate 25. Slots 27 are provided on one side of the collecting box 24 and one side of the hollow box 23, and positioning pins 26 are inserted into the slots 27.

[0030] As mentioned above, sulfur particles can be collected through the hollow box 23, and the inclined plate 25 plays a guiding role, which facilitates the particles to enter the collection box 24. In order to further improve the stability and replacement of the collection box 24, we have designed slots 27 on one side of the collection box 24 and one side of the hollow box 23. These two slots fit perfectly and a positioning pin 26 is inserted together. The insertion of the positioning pin 26 not only firmly locks the connection between the collection box 24 and the hollow box 23, but also ensures the stability of the collection box 24 during the collection process, and avoids the spillage of particles caused by shaking or vibration. Finally, optionally, a weight sensor can be installed inside the collection box 24. When the collected particles reach a preset weight, the sensor will send a signal to remind the operator to replace the collection box 24 in time.

[0031] A packing plate 47 is installed inside the treatment tower 41. The packing plate 47 is above the outlet pipe of the condenser 31 and below the nozzle 46. A filter discharge box 44 is provided at the bottom of the device base 1. The top of the filter discharge box 44 is designed to be open, and the discharge pipe at the bottom of the treatment tower 41 is covered inside. A composite filter screen 45 is installed on the inner wall of the filter discharge box 44, and a discharge pipe is installed on one side of the filter discharge box 44 below the composite filter screen 45.

[0032] By designing the packing plate 47, which is located above the outlet pipe of the condenser 31 and below the nozzle 46, such a layout allows the exhaust gas flowing out of the condenser 31 to first pass through the packing plate 47 area. The porous structure or special material on the packing plate 47 can increase the contact area between the exhaust gas and the packing, promote the chemical reaction between the hydrogen sulfide in the exhaust gas and the surface of the packing, and effectively improve the reaction efficiency.

[0033] A partition plate 412 is installed on the inner wall of the liquid tank 42, dividing the interior of the liquid tank 42 into two areas, which are used to hold weak alkaline liquid and hydrogen peroxide respectively. The inlet pipe of the pump 43 is "U"-shaped and penetrates into the two areas from the top of the liquid tank 42, and there are solenoid valves on both sides of the inlet pipe.

[0034] Through the above structural design, when it is necessary to use weak alkaline liquid for tail gas treatment, the "U"-shaped inlet pipe of the pump 43 will first extract the interval with weak alkaline liquid, and the valve on this side will be opened. At this time, by starting the pump, the weak alkaline liquid is accurately extracted and transported to the treatment tower 41, and the hydrogen sulfide in the gas reacts with the hydroxide ions in the solution to generate sodium sulfide and water. Then, when it is necessary to use hydrogen peroxide for tail gas treatment, the inlet pipe of the pump 43 will adjust its position and extend into the interval filled with hydrogen peroxide, open the solenoid valve on this side, close the other solenoid valve, and introduce hydrogen peroxide into the treatment tower 41. Hydrogen peroxide, as a strong oxidant, reacts with sodium sulfide to generate sulfur and water to complete the reaction treatment work.

[0035] A humidity sensor 33 is installed on the air outlet pipe of the condenser 31 , a hydrogen sulfide detection sensor 48 is installed on the air outlet pipe at the top of the treatment tower 41 , a PH sensor 49 is installed on the filter discharge box 44 , and the humidity sensor 33 is electrically connected to the air inlet valve of the condenser 31 .

[0036] As mentioned above, the humidity of the treated gas is detected by the humidity sensor 33. When the humidity of the outlet pipe is too high, impurities may clog the condenser 31. At this time, the operation can be stopped to maintain the condenser 31. The hydrogen sulfide detection sensor 48 detects the treated gas. When hydrogen sulfide is still detected, it means that the content is relatively high. The output efficiency of the pump 43 can be improved and the purification effect can be enhanced. Finally, the pH sensor 49 detects the pH of the filtered solution, which is very convenient.

[0037] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
