Abstract
Description
Technical Field
[0001] The invention relates to the technical field of waste gas treatment devices, and in particular to a waste gas collection and treatment device for petroleum coke calcining. Background Art
[0002] Waste gas treatment during petroleum coke calcination is an important environmental protection link in the petrochemical industry. Petroleum coke is a byproduct of petroleum refining, usually containing high carbon and impurities. A large amount of waste gas will be generated during the calcination process, including volatile organic compounds (VOCs), sulfides, nitrogen oxides (NOx) and particulate matter. If these waste gases are discharged directly without treatment, they will cause serious pollution to the environment. Therefore, the prior art, such as the Chinese patent with publication number: CN117942737A, discloses a waste gas collection and treatment device for petroleum coke calcination to treat this waste gas.
[0003] The existing waste gas collection and treatment device for petroleum coke calcining has inconsistent distribution content of pollutants in the waste gas during waste gas collection and treatment. When the existing equipment adsorbs pollutants in the waste gas through activated carbon, it usually adopts a flow-through method to make the waste gas pass through multiple activated carbons in sequence. However, since the content of pollutants in the waste gas is inconsistent, after the front activated carbon has completed the adsorption of pollutants in the waste gas, the waste gas needs to pass through the remaining activated carbon before it can be discharged, resulting in low exhaust efficiency.

[0004] In view of the above shortcomings of the prior art, the present invention provides a waste gas collection and treatment device for petroleum coke calcination, which can effectively solve the problem in the prior art that due to the uneven distribution of pollutants in the waste gas, the activated carbon in the front quickly reaches a saturated state, while the activated carbon in the back is still in an unsaturated state.

[0055] Step 1: First, the waste gas generated during the previous process is connected to the input pipe 44 through a pipeline, so that the high-temperature waste gas is guided to the S-shaped curved pipe 43 through the input pipe 44 (the waste gas generated by the calcination of petroleum coke is of high temperature because: the calcination process of petroleum coke is often carried out in a high-temperature furnace, such as a rotary kiln, a roasting furnace, etc. These furnaces work under high temperature conditions, and the waste gas will also absorb a large amount of heat when passing through the furnace body, thereby maintaining a high temperature, resulting in the temperature of the waste gas reaching the range of 800-1200°C). At the same time, the equipment is started. At this time, the controller controls the fan 48 located in the mounting block 47 to start (the controller is a prior art and is not drawn in the figure), and as the fan 48 is started (Note: when the fan 48 is started, the outside air is sucked into the cooling shell 41), the outside air will continuously enter the cooling shell 41, and at this time the high-temperature waste gas flowing in the S-shaped curved pipe 43 The S-shaped curved pipe 43 will exchange heat with the outside air entering the cooling shell 41 (the main constituent materials of the S-shaped curved pipe 43 are: copper, aluminum, etc., which are materials with good thermal conductivity), so that the outside air entering the cooling shell 41 and the high-temperature exhaust gas flowing in the S-shaped curved pipe 43 exchange heat, thereby heating the outside air (the outside air heated in the cooling shell 41 is hereinafter referred to as hot air), and at the same time, the high-temperature exhaust gas flowing in the S-shaped curved pipe 43 is cooled. Since the waste gas collection and treatment device for petroleum coke calcination generates a large amount of heat during operation, it is generally installed in a special area in the factory, and a good ventilation and cooling system is configured in this area to ensure that the air temperature in this area is maintained at a stable value (and the outside air in this scheme refers to the outside air in the equipment installation area), and this temperature range is generally between 20°C and 30°C;
[0056] At the same time, in order to enhance the heating effect (heat exchange efficiency) of the high-temperature exhaust gas flowing in the S-shaped curved pipe 43 on the air entering the cooling shell 41, the S-shaped curved pipe 43 is set to have multiple sections of S-shaped bends, which can effectively increase the flow time of the high-temperature exhaust gas in the S-shaped curved pipe 43, thereby extending the contact time between the high-temperature exhaust gas in the S-shaped curved pipe 43 and the air in the cooling shell 41, thereby improving the heat exchange efficiency between the high-temperature exhaust gas and the outside air, because each bend section of the high-temperature exhaust gas in the pipe will increase the flow path, so that it will pass through a longer time before reaching the output end. This extended flow time allows the high-temperature exhaust gas to have a longer contact time with the cooling medium (such as outside air), thereby improving the efficiency of heat transfer and dissipation. At the same time, the structure of the multiple sections of the S-shaped curved pipe 43 can guide the high-temperature exhaust gas to continuously turn along the inner wall of the pipe, thereby increasing the contact area between the high-temperature exhaust gas and the inner wall of the pipe. This design helps to enhance the heat exchange between the high-temperature exhaust gas and the inner wall of the pipe and improve the effect of heat exchange.
[0057] Among them, as the fan 48 continuously blows outside air into the cooling shell 41 (the outside air at this time also refers to the outside air in the equipment installation area, that is, the outside air temperature is maintained between 20°C and 30°C), the air pressure in the cooling shell 41 continues to rise, and the air pressure in the cooling shell 41 can only be reduced by the electric control heat exchanger 42 and the one-way valve assembly 46 in the cooling shell 41, and the electric control heat exchanger 42 is responsible for discharging the outside air in the cooling shell 41 into the corresponding purification area in the exhaust gas treatment mechanism 1 (the electric control heat exchanger 42 is controlled to be turned on or off by the controller, and when the electric control heat exchanger 42 is turned off, the outside air The one-way valve assembly 46 discharges the hot air heated by the high-temperature exhaust gas flowing through the S-shaped curved pipe 43 back into the outside environment. At this time, since the electric-controlled heat exchanger 42 is in a closed state, as the air pressure in the cooling shell 41 continues to increase, a downward air pressure is generated on the valve seat 465 in the one-way valve assembly 46, thereby separating the valve seat 465 from the valve body 461. In addition, in order to ensure that when the electric-controlled heat exchanger 42 is opened later, the outside air can smoothly pass through the electric-controlled heat exchanger 42 and enter the exhaust gas treatment mechanism 1, an elastic rod 464 is provided in the valve seat 465. The elastic rod 464 has a strong traction on the valve seat 465, so that the valve seat 465 and the valve body 461 can be separated only when the air pressure in the cooling shell 41 is higher than a certain value (the specific value is determined by the constituent material of the elastic rod 464 and the number of the elastic rods 464, and the staff can customize the value according to the use needs). As the valve seat 465 and the valve body 461 separate, the hot air in the cooling shell 41 also begins to be continuously discharged to the external environment, thereby maintaining the air pressure in the cooling shell 41 in a relatively stable range, thereby ensuring the stability of the air pressure in the cooling shell 41. , and also enhances the fluidity of the outside air, thereby enhancing the cooling effect of the outside air on the high-temperature exhaust gas flowing in the S-shaped curved pipe 43 (enhanced outside air fluidity can increase the intensity of convective heat exchange, and strong convection can make the heat exchange process between the high-temperature exhaust gas and the outside air more efficient, resulting in a faster drop in the exhaust gas temperature, especially in the S-shaped curved pipe 43, the enhanced air fluidity can more effectively take away the heat on the pipe surface, thereby improving the cooling effect on the high-temperature exhaust gas), and when one of the electrically controlled heat exchangers 42 is opened, the air pressure inside the cooling shell 41 is insufficient to support the opening of the one-way valve assembly 46.
[0058] Step 2: After the first step of processing, the temperature of the waste gas after cooling is lower than that when it is just input due to heat exchange with the outside air, and it is kept consistent with the temperature of the hot air in the cooling shell 41. Because in the cooling shell 41, the high-temperature waste gas in the S-shaped curved pipe 43 contacts the outside air in the cooling shell for heat exchange. Through this process, the heat of the high-temperature waste gas is transferred to the outside air of the cooling shell. This heat exchange gradually reduces the temperature of the high-temperature waste gas, while the air in the cooling shell absorbs heat and heats up. Finally, after sufficient heat exchange, the temperature of the high-temperature waste gas and the air in the cooling shell will tend to be consistent, and the temperature of the high-temperature waste gas and the outside air in the cooling shell will be introduced later. Note that at this time, the temperature of the high-temperature waste gas and the air in the cooling shell is higher than the outside air temperature;
[0059] The high-temperature exhaust gas is transported to the output pipe 45 through the S-shaped curved pipe 43, and the heat exchanger 49 provided in the output pipe 45 can further cool the high-temperature exhaust gas, so that the high-temperature exhaust gas is consistent with the environment (the heat exchanger 49 is a prior art, which mainly transfers the heat in the high-temperature exhaust gas to the cooling medium (such as air or water) through efficient heat conduction, so that the temperature of the exhaust gas is gradually reduced to a temperature close to that of the cooling medium. Under the action of the heat exchanger, a temperature difference is formed between the exhaust gas and the cooling medium, so that heat is continuously transferred from the exhaust gas to the cooling medium. Finally, the temperature of the exhaust gas will tend to the temperature of the cooling medium, and the temperature close to the ambient temperature is between 20°C and 30°C);
[0060] The output pipe 45 further transports the exhaust gas (the exhaust gas temperature at this time is close to the ambient temperature, both between 20°C and 30°C) to the first two-position three-way solenoid valve 25 (the first two-position three-way solenoid valve 25 is also controlled by the controller). At this time, the first two-position three-way solenoid valve 25 will open one of the two output ends, thereby transmitting the exhaust gas to the discharge box 21 on the same side of the connecting pipe 26 through the connecting pipe 26 fixedly connected to the output end, and the discharge box 21 is evenly divided into two parts by the isolation plate 22. When the connecting pipe 26 located on the same side transmits the exhaust gas to the same part of the discharge box 21, the connecting pipe 26 will be connected to each arc exhaust block 24 through the second solenoid valve 27 (the second solenoid valve 27 in each arc exhaust block 24 is connected to the controller, and only one second solenoid valve 27 can be opened at a time).
[0061] Among them, the distribution position of the arc-shaped exhaust block 24 in the discharge box 21 corresponds to the structure of the box body 11 in the exhaust gas treatment mechanism 1, and the box body 11 is also evenly divided into two parts through the partition plate 12, thereby forming two purification areas (these two purification areas correspond to the two parts of the discharge box 21 divided by the isolation plate 22), and multiple layered plates 13 further divide the two purification areas into multiple purification tanks (the number and position of the purification tanks correspond to the arc-shaped exhaust blocks 24), and activated carbon rods 14 are arranged in the layered plates 13 to absorb pollutants in the exhaust gas entering the purification tank.
[0062] At this time, the second solenoid valve 27 close to the first two-position three-way solenoid valve 25 is opened under the control of the controller, causing the exhaust gas to enter the corresponding position in the arc-shaped exhaust block 24, and the arc-shaped exhaust block 24 discharges the exhaust gas into the corresponding purification tank through the exhaust hole (each purification tank is a separate sealed space), so as to use the activated carbon rods 14 alternating with each other in the purification tank to complete the adsorption of pollutants in the exhaust gas entering the purification tank. At this time, the exhaust gas and the activated carbon rods 14 have the same temperature. The activated carbon rods 14 are cooled by the flow of the purified exhaust gas, so the temperature of the activated carbon rods 14 is also consistent with the exhaust gas and the ambient temperature (the cooling process of the activated carbon rods 14 by the purified exhaust gas will be introduced later), both of which are normal ambient temperatures. Keeping the exhaust gas and the activated carbon rods 14 at the same ambient temperature helps to improve the adsorption efficiency of the activated carbon, because at normal ambient temperature, the pore structure and surface activity of the activated carbon can remain stable, maximizing the adsorption of pollutants in the exhaust gas. The temperature consistency also avoids the fluctuation of the activated carbon performance caused by the temperature difference, and ensures its stable thermal regeneration ability. When the exhaust gas is continuously discharged into the corresponding purification tank through the arc exhaust block 24, the monitoring mechanism 3 located in the purification tank can detect the amount of exhaust gas discharged into the purification tank at this time and the content of pollutants in the exhaust gas (the specific function and working method of the monitoring mechanism 3 are explained in the third step). Of course, when the monitoring mechanism 3 detects that the exhaust gas pressure in the purification tank reaches a certain value, and the pollutants in the exhaust gas have not been completely adsorbed, the monitoring mechanism 3 will send a signal to the controller, and the controller will start the corresponding first air pump 151, so as to transfer the exhaust gas in the purification tank from one purification tank to another purification tank, thereby treating the exhaust gas that has not been purified in the previous purification tank. The waste gas is further purified and passes through multiple purification tanks in this order until the monitoring mechanism 3 in a certain purification tank detects that the waste gas meets the emission standards. Then, the waste gas will be discharged into the shunt pipe 56 from the second two-position three-way solenoid valve 55 in the purification tank. Under the action of the suction force of the second air pump 53, the shunt pipe 56 stores the purified waste gas in the air bag 52 (the temperature of the purified waste gas stored in the air bag 52 will not change, and the specific role of the gas stored in the air bag 52 will be described later), thereby avoiding the need for the waste gas after purification to be purified through the subsequent purification tank (each purification tank is provided with an activated carbon rod 14), thereby reducing the flow path during waste gas purification and improving the waste gas purification efficiency of the equipment;
[0063] At the same time, when the exhaust gas reaches the last purification tank in the purification zone, the first solenoid valve 16 will be activated, so that the two purification zones in the discharge box 21 are temporarily connected to each other, and then the exhaust gas is transferred to the purification tank of another purification zone, so that the exhaust gas continues to be purified in the purification tank of another purification zone. When the exhaust gas starts to transfer from one purification zone to another, it indicates that the activated carbon rods 14 in all the purification tanks in the previous purification zone are in a saturated state and have lost the function of purifying the exhaust gas. When the exhaust gas is completely transferred to another purification zone, the purification zone is completely closed. With the closure of the purification zone, the electric-controlled heat exchanger 42 at the corresponding position of the closed purification zone is opened (the two electric-controlled heat exchangers 42 cannot be opened at the same time, and only one of them can be opened in the same time period);
[0064] Among them, since the temperature of the high-temperature exhaust gas flowing in the S-shaped curved pipe 43 can reach the range of 800-1200°C, and the temperature for thermal regeneration of the activated carbon rod 14 requires a temperature between 600°C and 900°C, the high-temperature exhaust gas flows in the S-shaped curved pipe 43 and exchanges heat with the air in the cooling shell 41, thereby reducing the original high-temperature exhaust gas temperature of 800-1200°C to between 600°C and 900°C, and increasing the original 20-30°C air temperature in the cooling shell 41 to between 600°C and 900°C (when the high-temperature exhaust gas flows in the S-shaped curved pipe 43, the heat of the high-temperature exhaust gas is transferred through the S-shaped curved pipe The heat of the high-temperature exhaust gas in the S-shaped curved duct 43 is transferred to the air in the cooling shell 41, and the amount of high-temperature exhaust gas in the S-shaped curved duct 43 is less than the amount of air in the cooling shell 41, resulting in that in the S-shaped curved duct 43, when the heat of the high-temperature exhaust gas is transferred to the air in the cooling shell 41, the total heat of the exhaust gas is higher than the total heat of the air in the cooling shell. This is because the heat density of the exhaust gas is higher, while the heat density of the air in the cooling shell is lower. Due to the heat difference between the exhaust gas and the air during the heat transfer process, the heat will be transferred from the high-temperature exhaust gas to the cooling air until the heat is balanced. Finally, the temperatures of the exhaust gas and the air tend to an intermediate value of 600°C to 900°C to achieve heat exchange. It should be noted that there is a volume difference (equal to the gas volume difference) between the volume size of the cooling shell 41 and the total volume of the S-shaped curved pipe 43 in the cooling shell 41. This volume difference is based on the premise that the air in the cooling shell 41 and the exhaust gas in the S-shaped curved pipe 43 reach the pyrolysis temperature after dynamic heat equilibrium. According to the first law of thermodynamics, heat is always transferred from a high-temperature object to a low-temperature object. The heat of the high-temperature exhaust gas is gradually absorbed by the air in the cooling shell, causing the exhaust gas temperature to drop. At the same time, the air temperature in the cooling shell increases, thereby achieving a temperature balance. This heat exchange causes the exhaust gas temperature to drop from 800-1200°C to 600-900°C. , and the air temperature in the cooling shell rises to 600-900°C), so that the high-temperature exhaust gas is kept consistent with the air temperature in the cooling shell 41, so the air in the cooling shell 41 heated by the high-temperature exhaust gas can reach the temperature required for the thermal regeneration of the activated carbon rod 14, thereby realizing the thermal regeneration of the activated carbon rod 14 (the thermal regeneration principle of activated carbon is to heat the activated carbon to a high temperature, and the pollutants adsorbed on the surface of the high-temperature activated carbon are volatilized or decomposed. During the heating process, the organic matter adsorbed on the activated carbon is gasified or burned, the pores of the activated carbon are cleared, and its adsorption capacity is restored. After regeneration, the activated carbon can be reused to remove pollutants in gas or liquid);
[0065] When the electric-controlled heat transfer device 42 is opened to introduce high-temperature air into the purification zone, the second two-position three-way solenoid valve 55 located at the same position in the purification zone will be fully opened (the output end of the second two-position three-way solenoid valve 55 is opened to discharge the high-temperature air into the atmosphere. At this time, the output end of the second two-position three-way solenoid valve 55 is connected to the input end of the second two-position three-way solenoid valve 55 connected to the purification zone, and the input end connected to the shunt pipe 56 is closed);
[0066] Thereby, the thermal regeneration of the activated carbon rods 14 in the saturated state in the purification zone is completed, and based on this, the thermal regeneration of the activated carbon rods 14 in the two purification zones is completed in sequence (when the activated carbon rods 14 in one purification zone are thermally regenerated, the exhaust gas is purified in the other purification zone, and the two purification zones cannot perform thermal regeneration of the activated carbon rods 14 at the same time. At the same time, only the activated carbon rods 14 in one purification zone can be thermally regenerated, and the activated carbon rods 14 after thermal regeneration have a relatively high temperature, so the activated carbon rods 14 will be cooled by flowing through the purified exhaust gas later on), avoiding the operation of manually replacing the activated carbon and improving the utilization rate of the activated carbon.
[0067] Among them, after the activated carbon rod 14 completes thermal regeneration, the purified exhaust gas stored in the airbag 52 will be transported to the purification area by the second air pump 53 (the temperature of the purified exhaust gas will not change and will also be maintained between 20°C and 30°C). That is, the second air pump 53 transmits the purified exhaust gas stored in the airbag 52 to the diversion pipe 56, and then opens the two input ends of the second two-position three-way solenoid valve 55 (the two input ends of the second two-position three-way solenoid valve 55 are opened and the input end is closed), thereby completing the thermal regeneration of the activated carbon rod. 14 has a cooling effect (the electrically controlled heat transfer device 42 is in a closed state when the airbag 52 starts to transport gas), and when the gas transported in the purification area reaches a certain pressure value, the gas transported to the purification area will be discharged from the output end of the second two-position three-way solenoid valve 55 (that is, at this time, the input end of the second two-position three-way solenoid valve 55 connected to the shunt pipe 56 is closed, and the input end of the second two-position three-way solenoid valve 55 connected to the purification area is in an open state), and when the thermal regeneration and cooling of the activated carbon rods 14 in the purification area are completed, the second two-position three-way solenoid valve 55 will be completely closed.
[0068] Step 3: When the exhaust gas enters the purification tank, the detection component 31 of the monitoring mechanism 3 located in the purification tank is responsible for detecting the content of the exhaust gas in the purification tank, the content of pollutants in the exhaust gas and the proportion of different pollutants in the exhaust gas.
[0069] Among them, as the exhaust gas continues to enter the purification tank, the air pressure in the purification tank becomes stronger and stronger, and the stronger and stronger air pressure acts on the hemispherical cover 312 of the detection component 31, and the hemispherical cover 312 will further apply the air pressure to the compression barrel 311, thereby causing the compression barrel 311 to be compressed. As the compression barrel 311 is compressed, the hemispherical cover 312 will contact the pressure controller 313. When the pressure on the pressure controller 313 reaches a specified value (the specified value can be customized by the user according to actual needs), the first air pump 151 will start, thereby transferring the exhaust gas in the purification tank to the adjacent purification tank. When the pressure on the pressure controller 313 does not reach the specified value (just reaches the specified value), the detector 314 in the detection component 31 detects that the exhaust gas at this time meets the emission standards. , the first air pump 151 will not start, and the second two-position three-way solenoid valve 55 will be started, thereby transmitting the exhaust gas (purified exhaust gas) in the purification tank here to the air bag 52. When the detector 314 in the pressure controller 313 detects that the content of pollutants in the exhaust gas has not changed when the exhaust gas is transmitted from one purification tank to another purification tank, it indicates that the activated carbon rod 14 in the previous purification tank is already in a saturated state and cannot absorb the pollutants in the exhaust gas. Therefore, the monitoring mechanism 3 will control the second solenoid valve 27 corresponding to this purification tank to close, so that the exhaust gas no longer passes through this purification tank, thereby achieving the abandonment of this purification tank and preventing the exhaust gas from passing through this purification tank again (this purification tank indicates that the activated carbon rod 14 is already in a saturated state), thereby reducing the purification path of the exhaust gas and improving the purification efficiency of the exhaust gas.
[0070] Among them, the detection component 31 can control the indicator light 34 at the corresponding position to display different colors according to different detection results. For example, when the purification tank is abandoned, the indicator light 34 located here is displayed in red; when the pressure in the purification tank reaches a specified value and the purification of the exhaust gas has not been completed, the indicator light 34 here is displayed in yellow; when the pressure in the purification tank reaches a specified value and the purification of the exhaust gas is completed, the indicator light 34 here is displayed in green (this example is for illustration, and the specific prompt method of the indicator light 34 is customized according to actual needs).
[0071] Among them, all other electric drive devices in the equipment except the monitoring mechanism 3 are powered by an external power supply, and the power of the monitoring mechanism 3 comes from the power generation component 33 (the independent power supply can ensure that the monitoring mechanism 3 obtains a stable power supply, reducing equipment failures or data errors caused by power supply fluctuations or interference). Whether the exhaust gas is converted from one purification tank to another purification tank, or the exhaust gas is directly discharged from the current purification tank, the exhaust gas will generate airflow during transmission, and the airflow generated by the exhaust gas during transmission will be blocked by the force fan 333, thereby causing the force fan 333 to rotate, and with the rotation of the force fan 333, the generator 331 starts to work, and the generator 331 is provided with a permanent magnet stator and a coil rotor. When the generator 331 is subjected to the force fan 333 and rotates in a circle, the generator 331 will rotate at a high speed, thereby obtaining the rotation of the coil rotor, so that the generator 331 generates electricity, and half of the electricity generated by the generator 331 acts on the detection component 31 to cause operation, and the other half is stored in the battery 316 in the detection component 31 as a backup energy source.
