Description

Technical Field

[0001] The present invention relates to the technical field of petroleum refining tail gas treatment, and in particular to an environmentally friendly petroleum refining tail gas treatment device and a treatment method. Background Art

[0002] Environmentally friendly petroleum refining tail gas treatment devices refer to equipment or systems used to purify tail gas generated during the petroleum refining process. These devices effectively remove harmful substances in tail gas, such as sulfur dioxide, nitrogen oxides, particulate matter, volatile organic compounds, etc., through physical, chemical or biological methods to meet environmental emission standards.

[0003] After searching, the Chinese patent with announcement number CN216630096U discloses a petrochemical tail gas treatment equipment, including a water storage seat, an operation box and a filtering mechanism, the water storage seat includes a seat plate and a water tank, the water tank is installed on the upper end surface of the seat plate, and the water tank is fixedly connected to the seat plate, the operation box is installed on the upper end surface of the water tank, and the operation box is fixedly connected to the water tank, the filtering mechanism is installed in the middle of the operation box, and the filtering mechanism is rotatably connected to the operation box, ensuring that the user can stably support the installation of the water tank through the seat plate when using it, so that the user can store water through the water tank, and at the same time ensure that the user can support the installation of the operation box through the water tank for use, so that the user can connect the tail gas pipeline through the external air intake pipe to ensure that the tail gas can stably enter the interior of the operation box, but the above scheme still has the following shortcomings when actually used: In the above technical solution, the particulate impurities in the exhaust gas are filtered through a filter. Although the filter can be quickly replaced, the exhaust gas generated in the petroleum refining process often contains a large amount of particulate matter. These particulate matter not only has a wide variety and a wide particle size distribution, but also has an extremely high content. Under such working conditions, the filter can be easily blocked by the particulate matter in the exhaust gas in a short period of time, resulting in a sharp drop in filtration efficiency, thereby affecting the operating efficiency of the entire exhaust gas pretreatment system. Once the filter is blocked, not only the particulate matter in the exhaust gas cannot be effectively removed, but the fan energy consumption may also increase due to increased resistance, and even cause system failure. In addition, frequent filter replacement not only increases the labor intensity of the operator.

[0014] As a preferred technical solution of the present invention, the material baffle plate has the same width as the discharge hopper, and a material taking port is provided on the material storage box.

[0015] An environmentally friendly method for treating petroleum refining tail gas comprises the following steps: Step 1: The tail gas generated by the oil refining equipment enters the pretreatment pipe. The tail gas drives the impeller to rotate under the action of the flow rate, and then drives the rotating shaft and the driving gear to rotate. The driving gear meshes with the teeth on the inner side of the rotating ring, so that the rotating ring rotates along the mounting plate, and drives the transmission rod and the rotating sleeve to rotate synchronously. When the tail gas passes through the deflector, the particulate impurities in it are filtered out by the filter. The paddle on the rotating sleeve reciprocates the deflector and the filter, generating vibration, so that the particulate impurities on the filter are shaken off to the discharge hopper; Step 2: The shaken-off particulate impurities enter the storage box through the discharge hopper. The bottom aperture of the discharge hopper is designed to prevent the impurities from flowing back. The rotating sleeve at the bottom drives the eccentric wheel to rotate through the worm gear mechanism. The eccentric wheel pushes the push plate to slide, and then pushes the baffle plate to rotate to cover the bottom opening of the discharge hopper and push the impurities to gather at one end of the storage box. When too much impurities accumulate, the push plate triggers the press trigger, and the alarm sends a signal to prompt the staff to handle it; Step 3. The exhaust gas filtered by the filter enters the serpentine cooling pipe and flows. The uppermost rotating sleeve drives the connecting rod to rotate through the synchronous belt and bevel gear mechanism, and then drives the rotary vane pump to pump the coolant. The coolant enters the cooling chamber from the liquid storage tank through the liquid outlet pipe and flows in the opposite direction to the exhaust gas. After heat exchange, it returns to the rotary vane pump through the return pipe, and then circulates back to the liquid storage tank through the duct, so that the exhaust gas can be effectively cooled in the serpentine cooling pipe.

[0016] The present invention has the following beneficial effects: 1. By setting up linkage components, the particulate impurities in the exhaust gas can be effectively filtered through the filter to ensure that the exhaust gas reaches a certain degree of cleanliness before subsequent treatment. At the same time, the mechanical cooperation of the rotating sleeve and the paddle is used to realize the automatic vibration and cleaning of the filter, avoid filter blockage, improve pretreatment efficiency, and reduce the frequency of manual intervention and filter replacement; 2. By setting the aggregate assembly, the hopper and the storage box are practical, and the particulate impurities shaken off the filter are automatically collected for subsequent centralized processing. At the same time, when there are too many impurities in the storage box, the alarm is triggered by pushing the plate and pressing the trigger to notify the staff to handle it in time to avoid impurities overflowing or affecting the operation of the equipment; 3. By setting up a cooling component and adopting a serpentine cooling pipe design, the contact area and time between the exhaust gas and the coolant are increased, the cooling efficiency is improved, and the rotation of the rotating sleeve can drive the rotary vane pump to realize automatic circulation pumping of the coolant. No additional power source is required, which saves energy and reduces consumption. In addition, the coolant and the exhaust gas flow in the opposite direction, which enhances the heat exchange effect and further reduces the exhaust gas temperature, creating favorable conditions for subsequent treatment.

When the rotary vane pump is turned on, the coolant in the liquid storage tank 97 can enter the cooling chamber 910 through the liquid outlet pipe 912 and flow in the opposite direction of the exhaust gas, and can enter the rotary vane pump body 91 through the liquid return pipe 913 for pumping, and the coolant pumped by the rotary vane pump can re-enter the liquid storage tank 97 through the conduit 911 for circulation cooling, so that the exhaust gas in the serpentine cooling pipe 98 can be cooled for subsequent treatment.

10. An environmentally friendly petroleum refining tail gas treatment method, based on an environmentally friendly petroleum refining tail gas treatment device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: The tail gas generated by the petroleum refining equipment enters the pretreatment pipe (1). The tail gas drives the impeller (6) to rotate under the action of the flow rate, thereby driving the rotating shaft (5) and the driving gear (710) to rotate. The driving gear (710) meshes with the teeth (713) on the inner side of the rotating ring (72), so that the rotating ring (72) rotates along the mounting plate (71), and drives the transmission rod (74) and the rotating sleeve (73) to rotate synchronously. When the tail gas passes through the guide cover (2), the particulate impurities therein are filtered out by the filter screen. The paddle (76) on the rotating sleeve (73) reciprocates the guide cover (2) and the filter screen, generating vibration, so that the particulate impurities on the filter screen are shaken off to the discharge hopper (81); Step 2: The particulate impurities that have been shaken off enter the storage box (82) through the discharge hopper (81). The bottom opening of the discharge hopper (81) is designed to prevent the impurities from flowing back. The bottom rotating sleeve (73) drives the eccentric wheel (85) to rotate through the worm gear (83) and worm (84) mechanism. The eccentric wheel (85) pushes the push plate (87) to slide, thereby pushing the baffle plate (86) to rotate to cover the bottom opening of the discharge hopper (81) and push the impurities to gather at one end of the storage box (82). When too much impurities are accumulated, the push plate (87) triggers the press trigger (89), and the alarm sends a signal to prompt the staff to handle it. Step 3: The exhaust gas filtered by the filter enters the serpentine cooling pipe (98) and flows therein. The uppermost rotating sleeve (73) drives the connecting rod (95) to rotate through the synchronous belt and the bevel gear mechanism, thereby driving the rotary vane pump to pump the coolant. The coolant enters the cooling chamber (910) from the liquid storage tank (97) through the liquid outlet pipe (912) and flows in the opposite direction to the exhaust gas. After heat exchange, the coolant returns to the rotary vane pump through the liquid return pipe (913), and then circulates back to the liquid storage tank (97) through the conduit (911), so that the exhaust gas is effectively cooled in the serpentine cooling pipe (98).
