Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for fluidized bed reactors, specifically to an air intake dust removal device for a fluidized bed reactor. Background Technology

[0002] The existing dust removal devices for the inlet of fluidized bed reactors are generally bag filters, which use filter bags to intercept and filter dust in the gas, effectively removing fine dust particles and playing an important role in improving the cleanliness of the inlet air.

[0003] However, when hot and humid gas enters the baghouse dust collector, the moisture in the airflow condenses upon cooling, causing the filter bags to become damp. At this point, dust easily adheres to the surface of the filter bags, gradually accumulating and clogging the pores. In this situation, even pulse-jet cleaning methods are insufficient to effectively remove the adhered dust, leading to filter bag clogging. High-temperature environments accelerate the aging of filter bags, shortening their lifespan. Frequent filter bag replacements not only increase production costs but also disrupt production continuity due to equipment downtime for maintenance, reducing production efficiency and posing limitations. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an air intake dust removal device for a fluidized bed reactor, which solves the problems of difficult dust removal, rapid aging of filter bags, and short service life of the device caused by high-temperature and high-humidity gas entering the bag filter.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an air intake dust removal device for a fluidized bed reactor, comprising a fluidized bed reactor arranged on one side of a bag filter, and a cooling and dehumidification unit arranged on the other side of the bag filter, wherein the cooling and dehumidification unit includes a housing, a condenser plate, and a spray cleaning component;

[0006] The housing is connected to the bag filter; the condenser plate is installed inside the housing and is arranged in an equidistant array. The condenser plate is used to condense the gas inside the housing; the spray cleaning component is installed on the condenser plate and is used to spray and clean the condenser plate.

[0007] Preferably, an air inlet is fixedly mounted on the top of the housing.

[0008] Preferably, a drain pipe is fixedly installed at the top of the condenser plate, and a water inlet pipe is fixedly installed at the bottom of the condenser plate.

[0009] Preferably, a guide bucket is fixedly installed at the bottom of the inner part of the box, and a water outlet pipe is fixedly installed at the bottom of the guide bucket. The water outlet pipe is equipped with a valve inside.

[0010] Preferably, an air outlet pipe is fixedly installed on one side of the housing. The air outlet pipe is inclined as a whole, with the lower end on the side closest to the housing. The air outlet pipe is connected to the bag filter dust collector.

[0011] Preferably, the spray cleaning component includes a water supply pipe and a spray nozzle;

[0012] The water supply pipe is installed on the condenser plate and is arranged in an equidistant array; the nozzle is fixedly mounted on the water supply pipe and is arranged in an equidistant array, with the nozzle facing the side wall of the condenser plate.

[0013] Preferably, the spray cleaning component further includes a tilting plate and a conveying pipe;

[0015] Its beneficial effects are as follows:

[0016] This device uses a condenser plate to condense high-temperature and high-humidity gas, reducing the gas temperature and humidity, and decreasing the amount of water vapor entering the bag filter. This effectively alleviates the problem of dust adhering to the filter bags due to water vapor, making dust removal easier. At the same time, it lowers the gas temperature, reducing the damage to the filter bags caused by temperature, thus meeting the needs of users. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] This utility model discloses an air inlet dust removal device for a fluidized bed reactor, according to the attached... Figure 1-3 As shown, a fluidized bed reactor is provided on one side of the bag filter 1, and a cooling and dehumidification unit 2 is provided on the other side of the bag filter 1. The cooling and dehumidification unit 2 includes a housing 21, a condenser plate 22, and a spray cleaning component 23.

[0026] The housing 21 is connected to the bag filter 1; the condenser plate 22 is installed inside the housing 21, and the condenser plates 22 are arranged in an equidistant array. The condenser plates 22 are used to condense the gas inside the housing 21; the spray cleaning component 23 is installed on the condenser plate 22 and is used to spray and clean the condenser plate 22.

[0027] An air inlet 24 is fixedly installed on the top of the housing 21. A drain pipe 25 is fixedly installed on the top of the condenser plate 22, and a water inlet pipe 26 is fixedly installed on the bottom of the condenser plate 22. A guide hopper 27 is fixedly installed at the bottom of the inner part of the housing 21, and a water outlet pipe 28 is fixedly installed at the bottom of the guide hopper 27. A valve is installed inside the water outlet pipe 28. An air outlet pipe 29 is fixedly installed on one side of the housing 21. The air outlet pipe 29 is inclined, with the lower end near the housing 21. The air outlet pipe 29 is connected to the bag filter 1.

[0028] In this embodiment, high-temperature and high-humidity gas enters the interior of the housing 21 through the air inlet 24. At this time, coolant is injected into the interior of the condenser plate 22 through the water inlet pipe 26 and discharged through the drain pipe 25. The flow direction is opposite to that of the hot air, which can cool the hot air more quickly. The water vapor inside the hot air condenses when it comes into contact with the cold condenser plate 22. The condensed liquid flows into the guide hopper 27 and is collected. It is discharged through the water outlet pipe 28. The low-temperature and dry gas is transported to the interior of the bag filter 1 through the air outlet pipe 29. After dust removal, it enters the interior of the fluidized bed for reaction.

[0029] According to the appendix Figure 1 , 4 As shown, further, a fluidized bed reactor is provided on one side of the bag filter 1, and a cooling and dehumidification unit 2 is provided on the other side of the bag filter 1. The cooling and dehumidification unit 2 includes a housing 21, a condenser plate 22 and a spray cleaning component 23.

[0030] The housing 21 is connected to the bag filter 1; the condenser plate 22 is installed inside the housing 21, and the condenser plates 22 are arranged in an equidistant array. The condenser plates 22 are used to condense the gas inside the housing 21; the spray cleaning component 23 is installed on the condenser plate 22 and is used to spray and clean the condenser plate 22.

[0031] The spray cleaning component 23 includes a water supply pipe 231 and a nozzle 232. The water supply pipe 231 is disposed on the condenser plate 22 and is arranged in an equidistant array. The nozzle 232 is fixedly mounted on the water supply pipe 231 and is also arranged in an equidistant array, with the nozzles facing the side wall of the condenser plate 22. The spray cleaning component 23 also includes a tilting plate 233 and a conveying pipe 234. One side of the tilting plate 233 is hinged to the end of the nozzle 232, and a torsion spring is provided at the connection between the tilting plate 233 and the nozzle 232. The conveying pipe 234 is disposed on one side of the water supply pipe 231 and communicates with the water supply pipe 231.

[0032] In this embodiment, after the device completes gas purification and shuts down, dust from the gas adheres to the condenser plate 22. At this time, the spray cleaning unit 23 is activated to clean the condenser plate 22. Water is delivered from the delivery pipe 234 to the water supply pipe 231, which distributes the water to each nozzle 232. The water flow impacts the flip plate 233 at the end of the nozzle 232, causing the flip plate 233 to open. Water is sprayed from the nozzle 232 towards the side wall of the condenser plate 22, providing a comprehensive spray cleaning. Wastewater generated during cleaning is collected in the guide bucket 27 and discharged through the outlet pipe 28. After cleaning, the water supply is stopped, and the flip plate 233 closes under the action of a torsion spring. This cleaning process effectively removes dust adhering to the condenser plate 22, ensuring its condensation effect.
