Description

Technical Field

[0001] This utility model relates to the field of exhaust technology for catalyst regeneration furnaces, specifically to a fan switching exhaust mechanism for a catalyst regeneration furnace. Background Technology

[0002] The exhaust system of the catalyst regeneration furnace is a key component ensuring stable furnace pressure and continuous regeneration process. It typically consists of dual fans, a linked switching valve group, a pressure / flow monitoring unit, and an automatic control system. Its core function is to trigger the rapid start of the backup fan via the control system when the main fan needs maintenance or fails. Simultaneously, it links and switches the valves in the corresponding exhaust pipe, ensuring that high-temperature exhaust gas (containing catalyst regeneration reaction products) is consistently and continuously discharged from the regeneration furnace. This prevents sudden pressure increases / decreases that could cause fluctuations in regeneration efficiency or equipment safety risks, achieving uninterrupted exhaust function during fan switching.

[0003] However, the existing fan switching exhaust mechanism of the catalyst regeneration furnace still has significant shortcomings in practical applications. On the one hand, although the mechanism is equipped with a filter to avoid environmental pollution from impurities in the exhaust gas, the design logic of the existing switching exhaust structure is usually to maintain or replace the filter only after the fan switching operation is completed. This delayed operation is not only cumbersome, but also highly dependent on manual labor for disassembly, cleaning, and reassembly, which increases the labor intensity of personnel and may also cause the exhaust system to temporarily stop or the filtration effect to decrease due to the operation interval, resulting in poor ease of use.

[0004] On the other hand, the gas discharged from the catalyst regeneration furnace often contains a certain amount of water vapor. Existing facilities do not have a pretreatment process for this characteristic, allowing the humid gas to directly enter the filtration device. When water vapor comes into contact with the filter medium, it easily condenses on the surface of the medium and adheres with a large amount of moisture. This not only clogs the filter pores and reduces the filtration efficiency, but may also cause the medium to become damp and deteriorate, shortening its service life or usage cycle. This, in turn, frequently causes fluctuations in filtration performance, posing significant challenges to the stable operation of the regeneration furnace exhaust system and environmental compliance.

[0006] In view of the problems existing in the above and / or existing blower switching exhaust mechanism of catalyst regeneration furnace, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a blower switching exhaust mechanism for a catalyst regeneration furnace.

[0008] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0009] A blower switching exhaust mechanism for a catalyst regeneration furnace includes: a blower body; a three-way pipe connected between multiple blower bodies; an electrically adjustable ball valve installed on the outer wall of the three-way pipe; a wind pressure sensor installed on the inner wall of the three-way pipe; processing components connected to the suction ends of the multiple blower bodies; a fixed box installed at the suction end of the blower body; an impurity collection component and a refrigeration device installed on the outer wall of the fixed box; a drive component installed on the top of the fixed box; a fixed frame installed on the top of the fixed box; a two-way pipe connected between the multiple processing components; an electrically adjustable ball valve installed on the outer wall of the two-way pipe; and a condenser pipe installed inside the fixed box.

[0011] As a preferred embodiment of the blower switching exhaust mechanism of the catalyst regeneration furnace described in this utility model, an electric push rod is provided at the top of the fixed frame, the output end of the electric push rod is connected to a connecting frame, and the bottom of the connecting frame extends into the fixed box and is connected to a lifting frame and a water passage box.

[0012] As a preferred embodiment of the blower switching exhaust mechanism of the catalyst regeneration furnace described in this utility model, the bottom of the lifting frame is provided with a slot, and the top of the lifting frame is connected to a fixed pipe, which extends to the top of the fixed box.

[0014] As a preferred embodiment of the blower switching exhaust mechanism of the catalyst regeneration furnace described in this utility model, a water pump and a drain valve are provided on the outer wall of the fixed box. The drain end of the water pump is connected to a metal pipe. The end of the metal pipe is connected to the outer wall of the water passage box through a water supply hose and communicates with its interior. A water pipe rack is connected to the outer wall of the water passage box, and a water spray nozzle is opened on the outer circumference of the water pipe rack.

[0015] As a preferred embodiment of the blower switching exhaust mechanism of the catalyst regeneration furnace described in this utility model, a metal perforated plate frame is connected to the inner wall of the fixed box, and a water filter membrane is snapped into the inside of the metal perforated plate frame.

With the help of the water pump, the filtered water can be reused, allowing the outer circumference of the condenser tube to be flushed and cleaned, reducing the adhesion of impurities and affecting its condensation efficiency.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] This utility model provides a blower switching and exhaust mechanism for a catalyst regeneration furnace, comprising: a blower body 100; a three-way pipe 110 connecting multiple blower bodies 100; an electric regulating ball valve 120 installed on the outer wall of the three-way pipe 110; a wind pressure sensor 130 installed on the inner wall of the three-way pipe 110; processing components connected to the suction ends of multiple blower bodies 100; a fixed box 200 installed at the suction end of the blower body 100; an impurity collection component and a refrigeration device 230 installed on the outer wall of the fixed box 200; a drive component installed on the top of the fixed box 200; a fixed frame 240 installed on the top of the fixed box 200; a two-way pipe 300 connecting multiple processing components; an electric regulating ball valve 480 installed on the outer wall of the two-way pipe 300; and a condenser pipe 232 installed inside the fixed box 200.

[0032] Refer to the following in this embodiment Figure 1 The core of this mechanism comprises three main modules: the main fan body 100, the processing components, and the pipeline control unit. Multiple main fan bodies 100 are configured (for primary / standby switching), and these main fan bodies 100 are connected via a T-connector 110. The outer wall of the T-connector 110 is equipped with an electrically adjustable ball valve 120 (for controlling pipeline on / off and flow regulation), while the inner wall is equipped with a wind pressure sensor 130 (for real-time monitoring of wind pressure within the pipeline, providing data for fan switching and valve adjustment). Simultaneously, the multiple main fan bodies 100... Each suction end is connected to a set of processing components for pre-treating the gas entering the fan. Multiple processing components are connected by a three-way pipe 2 300. The outer wall of the three-way pipe 2 300 is equipped with an electric regulating ball valve 2 480 (to assist in switching the path and coordinating the work between multiple processing components). The electric regulating ball valve is a common three-way ball valve. The wind pressure sensor 130 and the fan body are existing technologies and common models on the market can be selected, which do not need to be elaborated. The control of this device can be controlled by an external PLC controller.

[0033] Specifically, the impurity collection assembly includes a connecting shell 220 installed on the outer wall of the fixed box 200, a bag collector 221 threaded onto the outer wall of the connecting shell 220, and a cover plate 210 provided on the front outer wall of the multiple fixed boxes 200 to facilitate the collection of impurities on the filter plate 281.

[0034] Specifically, the top of the fixed frame 240 is provided with an electric push rod 241, the output end of the electric push rod 241 is connected to a connecting frame 242, and the bottom of the connecting frame 242 extends into the fixed box 200 and is connected to a lifting frame 243 and a water box 244, which facilitates the cleaning of the condenser pipe 232.

[0035] Specifically, the bottom of the lifting frame 243 is provided with a slot, and the top of the lifting frame 243 is connected to a fixing pipe 250, which extends to the top of the fixing box 200.

[0036] Specifically, a blower 231 is provided on the top of the refrigeration device 230. The air supply end of the blower 231 is connected to the outer circumference of the fixed pipe 250. The output end and the recovery end of the refrigeration device 230 are respectively sealed and connected to the end and the end of the condenser pipe 232.

[0037] In some embodiments, the core working principle of the refrigeration device 230 is based on a vapor compression refrigeration cycle (or an absorption or semiconductor refrigeration cycle adapted according to the actual design). Through the coordinated operation of four core components—an internal compressor, condenser, expansion valve, and evaporator (integrated with the condenser tube 232)—the refrigerant undergoes a phase change and heat transfer: First, the compressor compresses the low-temperature, low-pressure refrigerant vapor into high-temperature, high-pressure vapor. Then, the high-temperature vapor enters the condenser, releases heat, and condenses into high-pressure liquid refrigerant. Next, the liquid refrigerant is throttled and depressurized by the expansion valve, becoming a low-temperature liquid. The low-pressure gas-liquid mixture then enters the condenser tube 232 (i.e., the evaporator). Inside the condenser tube 232, the low-temperature refrigerant absorbs heat from the gas to be treated in the fixed box 200, rapidly vaporizing into low-pressure steam. At the same time, the water vapor in the gas condenses into liquid water (achieving dehumidification). The vaporized refrigerant vapor then flows back to the compressor, completing the cycle. Throughout the process, the refrigeration device 230 continuously exchanges heat to reduce the gas temperature in the fixed box 200 and separate water vapor, providing a dry gas environment for the subsequent filter components and preventing moisture from affecting the filtration performance. All of the above are existing technologies and need not be elaborated further.

[0038] Specifically, a water pump 260 and a drain valve 261 are provided on the outer wall of the fixed box 200. The drain end of the water pump 260 is connected to a metal pipe. The end of the metal pipe is connected to the outer wall of the water box 244 through a water delivery hose and communicates with its interior. A water pipe rack 245 is connected to the outer wall of the water box 244. A water spray nozzle 246 is opened on the outer circumference of the water pipe rack 245.

[0039] Specifically, a metal perforated plate frame 270 is connected to the inner wall of the fixed box 200, and a water filter membrane 271 is snapped into the inside of the metal perforated plate frame 270.

[0040] In some embodiments, the water filter membrane 271 may be made of polyester fiber material, and its filter plate 281 may be made of honeycomb activated carbon material.

[0041] Specifically, the inner wall of the fixed box 200 is also provided with a snap-fit ​​seat 280, the outer wall of the snap-fit ​​seat 280 is fixedly connected with a filter plate 281, the bottom of the lifting frame 243 is integrally formed with a shielding protrusion, and the outer wall of the snap-fit ​​seat 280 is provided with a through opening.

[0042] In some embodiments, when the lifting frame 243 is attached to the top of the filter plate 281, its shielding protrusion can block the through-hole, reducing the amount of impurities blown into the condensation area from the bottom of the filter plate.

[0043] In some embodiments, the device can be powered by an external power source.

[0044] In this embodiment, during actual use, the device can detect the airflow of a specified fan using the wind pressure sensor 130. When the airflow is below a certain value, the electric regulating ball valve 120 and the electric regulating ball valve 480 can be activated to adjust the airflow so that another fan can be started. The problematic fan can then be checked by personnel. If it is only caused by filter media blockage, the electric push rod 241 can be activated to drive the lifting frame 242 down, and then the blower 231 can be activated. The blower 231 will then blow air through the slot at the bottom of the lifting frame 243. When the lifting frame 243 is attached to the filter plate 281, the impurities attached to the bottom of the filter plate 281 can be cleaned by the wind pressure and collected by the bag collector 221, which makes it easier to clean the filter plate 281 and reduces the trouble caused by frequent disassembly and cleaning by personnel.

[0045] Furthermore, the device is equipped with a condenser tube 232, which can condense the discharged gas, reducing the impact of excessive moisture in the discharged gas on the service life of the filter plate 281. Secondly, the water condensed by the condenser tube 232 can be filtered through the water filter membrane 271. During the descent of the lifting frame 243, the water pipe frame 245 can be driven down. With the help of the water pump 260, the filtered water source can be reused, allowing it to flush and clean the outer circumference of the condenser tube 232, reducing the adhesion of impurities and affecting its condensation efficiency.

[0046] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation.
