Description

TECHNICAL FIELD

The fluidized drying system forms an upward airflow by uniformly distributing dry gas (such as hot air or nitrogen) into the bottom of the storage tank through a porous fluidization plate, so that the powder is in a fluidized state when reaching the minimum fluidization speed, avoiding local accumulation and caking. The characteristics of the storage and conveying of the storage tank determine that a plurality of pipelines with different functions are connected to the storage tank, and the connection and sealing failure of the storage tank and the pipeline is the core risk point of the external moisture intrusion. The traditional device only relies on passive protection of the static sealing ring, lacks real-time monitoring and active emergency mechanism for leakage, and when the sealing fails, external moisture penetrates into the tank through the connection gap, causing the treatment agent (such as sodium bicarbonate) in the storage tank to absorb moisture and caking. At this time, manual inspection of the sealing, heat preservation, fluidization system and other links is required, which is time-consuming and inefficient, and the connection pipeline is numerous, which will also cause the problem of low efficiency of pipeline sealing inspection. Based on this, the present application provides an industrial flue gas desulfurization and denitrification treatment agent storage conveying device which can improve the response speed and processing efficiency of the leakage problem of the tank body connection pipeline.

[0012] The present application has the following beneficial effects: 1. In the present application, an annular cover is arranged at the connection between each pipeline on the storage tank and the pipeline of external equipment.

In the present application, when the external air enters the extension pipe, the flow area gradually decreases, resulting in an increase in air flow rate. Faster airflow can drive the turbine to rotate faster, so that the rotating rod rotates faster, improving the speed of the sliding block abutting against the trigger switch. In this way, the same amount of external air entering the annular cover can trigger the trigger switch faster, thereby accelerating the operation of starting the electric cylinder to extend and push the sealing plate to block the air inlet of the extension pipe, avoiding more external air entering the annular cover.

[0017] Please refer to Figures 1-5 The present application is an industrial flue gas desulfurization and denitrification treatment agent storage and conveying device, which comprises: The storage tank 1 is provided with a feed pipe 2 on the outer circular surface, the feed pipe 2 is sealingly connected with a first connecting pipe 3 through a flange, the top of the storage tank 1 is connected with a gas outlet pipe 4, the gas outlet pipe 4 is sealingly connected with a second connecting pipe 5 through a flange, the bottom of the storage tank 1 is connected with a discharge pipe 7 and a gas conveying pipe 6, a porous fluidization plate 11 is arranged at the bottom plate of the storage tank 1, the porous fluidization plate 11 is connected with the gas conveying pipe 6, an annular cover 10 is sleeved on the connection between the feed pipe 2 and the first connecting pipe 3 and the connection between the gas outlet pipe 4 and the second connecting pipe 5, each annular cover 10 is connected with an extension pipe 12, a turbine 14 is rotatably installed in each extension pipe 12, and a fixed frame 13 is sleeved on the outer circular surface of each extension pipe 12, an electric cylinder 23 is fixedly installed on the fixed frame 13, a sealing plate 16 is fixedly installed on the movable end of the electric cylinder 23, an outer annular sealing ring 17 is fixedly installed on the side of the sealing plate 16 close to the extension pipe 12, and the sealing plate 16 is away from the extension pipe 12 when the electric cylinder 23 is contracted; Trigger assembly, the trigger assembly is arranged on the fixed frame 13, the turbine 14 is connected with the electric cylinder 23 through the trigger assembly, when the air pipe 6 transports air to the storage tank 1 through the porous fluidization plate 11 and is discharged through the air outlet pipe 4 and the second connecting pipe 5, when the storage tank 1 is communicated with the external air through the annular cover 10 and the extension pipe 12, the external air is sequentially passed through the extension pipe 12 and the annular cover 10, the air flow drives the turbine 14 to rotate, and the turbine 14 controls the electric cylinder 23 to extend through the trigger assembly, so that the sealing plate 16 is close to the extension pipe 12 and the outer annular sealing ring 17 is extruded to realize sealing.

[0018] In one case of the embodiment, the air pipe 6 is used to transport heated gas, the first connecting pipe 3 is communicated with the feeding device, the second connecting pipe 5 is connected with the air filtering mechanism, and the connecting positions of the feeding pipe 2 and the first connecting pipe 3 and the connecting positions of the air outlet pipe 4 and the second connecting pipe 5 are the connecting positions of the pipes on the storage tank 1 and the pipes of external equipment, which need to be sealed, in fact, there are many pipes on the storage tank 1, and the annular cover 10 is arranged at the connecting position of each pipe and the pipe of external equipment, it should be noted that the electric cylinder 23 of the application is prior art, and the application does not improve them, therefore, the specific mechanical structure and circuit structure of the electric cylinder 23 do not need to be disclosed, and the integrity of the application is not affected.

[0019] The working principle of the application is as follows: firstly, sodium bicarbonate powder can be transported into the storage tank 1 through the first connecting pipe 3 and the feeding pipe 2 as raw material storage, when flue gas desulfurization and denitrification treatment is needed, the sodium bicarbonate powder can be discharged through the discharge pipe 7, in daily storage, heated gas is introduced through the air pipe 6, after the hot gas is blown out from the porous fluidization plate 11, the material is fluidized, and the hot gas can fully contact with the material to transfer heat, so that the purpose of drying or preheating is achieved, and the gas is discharged from the air outlet pipe 4 and the second connecting pipe 5 after rising in the storage tank 1; When the connecting positions of the feeding pipe 2 and the first connecting pipe 3 and the connecting positions of the air outlet pipe 4 and the second connecting pipe 5 leak, when the hot gas flows in the storage tank 1, a negative pressure environment is formed in the storage tank 1, then the external air enters the storage tank 1 from the leakage, and the external air contains moisture, which can make the sodium bicarbonate raw material damp and clump, thereby affecting the storage and use of the material; The external air enters the inlet of the extension pipe 12 first, then enters the annular cover 10, and finally enters the storage tank 1 from the sealing leakage. In the process of the external air entering the annular cover 10 from the extension pipe 12, the airflow drives the turbine 14 arranged in the extension pipe 12 to rotate, and the rotation of the turbine 14 controls the electric cylinder 23 to extend through the triggering assembly, so that the sealing plate 16 is close to the extension pipe 12 and the outer annular sealing ring 17 is extruded to realize sealing, thereby blocking the inlet of the extension pipe 12 and realizing emergency sealing of the sealing leakage, avoiding the problem that the materials in the storage tank 1 are damp, and avoiding the problem that whether the sealing failure occurs is judged by detecting whether the sodium bicarbonate absorbs and agglomerates, so that part of the raw materials have been damp, thereby needing to be dried again. According to the extension condition of the electric cylinder 23, it can be directly judged that which part of the pipeline connected to the storage tank 1 appears the sealing failure, so as to be processed in a targeted manner, without the need to check the sealing condition of each pipeline connection one by one, thereby improving the problem processing efficiency.

[0020] As shown in Figures 1-5 As a preferred embodiment of the present application, the triggering assembly includes a rotating rod 15, a guide rod 21, a sliding block 20 and a trigger switch 22. The rotating rod 15 is rotatably installed on the fixed frame 13, and the rotating rod 15 penetrates the sealing plate 16 and is coaxially fixedly connected with the turbine 14. The rotating rod 15 is slidably connected with the sealing plate 16. The end of the rotating rod 15 away from the turbine 14 is provided with a threaded section. The guide rod 21 is fixedly installed on the fixed frame 13. The end of the guide rod 21 is fixedly installed with the trigger switch 22. The trigger switch 22 is connected with the electric cylinder 23. The guide rod 21 is slidably installed with the sliding block 20. The sliding block 20 is threadedly connected with the threaded end of the rotating rod 15. When the air enters the annular cover 10 from the extension pipe 12, the airflow drives the turbine 14 to rotate, and the turbine 14 drives the rotating rod 15 to rotate, so that the sliding block 20 moves towards the trigger switch 22.

[0021] In actual application, when the airflow drives the turbine 14 to rotate, the turbine 14 drives the rotating rod 15 to rotate, and the threaded segment of the rotating rod 15 and the sliding block 20 are threadedly connected, so that the rotating rod 15 drives the sliding block 20 to move, and finally the sliding block 20 abuts against the trigger switch 22, so that the electric cylinder 23 is opened, the electric cylinder 23 is extended, the electric cylinder 23 drives the sealing plate 16 to move, the sealing plate 16 slides on the rotating rod 15, and finally the sealing plate 16 abuts against the air inlet of the extension pipe 12. The sealing plate 16 and the extension pipe 12 extrude and deform the outer annular sealing ring 17, so as to block the air inlet of the extension pipe 12 to form a seal. Once the connection leaks, the airflow generated by the inflow of external air into the extension pipe 12 can immediately drive the turbine 14 to rotate, quickly trigger a series of subsequent actions, and quickly realize the blocking and sealing of the air inlet of the extension pipe 12. Compared with the traditional way of relying on detection equipment to find problems and then processing, the time from leakage to taking measures is greatly shortened, more humid air can be prevented from entering at the first time, the influence on the sodium bicarbonate raw material in the storage tank 1 is minimized, and the problem of massive material dampening and caking is avoided.

[0022] As shown in Figures 4-5 , as a preferred embodiment of the present application, the outer circular surface of the rotating rod 15 is fixedly installed with a fixed ring 19, and the side of the sealing plate 16 close to the extension pipe 12 is fixedly installed with an inner annular sealing ring 18. When the sealing plate 16 is close to the extension pipe 12 to extrude the outer annular sealing ring 17, the sealing plate 16 and the fixed ring 19 simultaneously extrude and deform the inner annular sealing ring 18.

[0023] In actual application, considering that external air will enter the extension pipe 12 from the gap between the sliding connection of the sealing plate 16 on the rotating rod 15, the fixed ring 19 is arranged on the rotating rod 15. When the sealing plate 16 is close to the extension pipe 12 to extrude the outer annular sealing ring 17, the sealing plate 16 and the fixed ring 19 simultaneously extrude and deform the inner annular sealing ring 18, so that the air entering from the gap between the sealing plate 16 and the rotating rod 15 is blocked by the inner annular sealing ring 18, avoiding the inflow of external air into the extension pipe 12, and ensuring that the storage tank 1 can restore the sealing performance of the extension pipe 12 by the operation of the sealing plate 16 after the sealing failure, avoiding the problem of sodium bicarbonate dampening and caking in the storage tank 1.

[0024] As shown in Figures 1-5 , as a preferred embodiment of the present application, the air inlet end of the extension pipe 12 is designed in a conical shape, and the pipe radius of the extension pipe 12 decreases along the air inlet path, and the turbine 14 is close to the connection between the extension pipe 12 and the annular cover 10.

[0025] In actual application, the extension pipe 12 is designed as a taper at the air inlet end, and the pipe radius of the extension pipe 12 decreases along the air inlet path. When the external air enters the extension pipe 12, the flow area gradually decreases, resulting in an increase in the air flow rate. The faster airflow can drive the turbine 14 to rotate faster, so that the rotating rod 15 rotates faster, and the speed of the sliding block 20 abutting against the trigger switch 22 is increased. Thus, the same amount of external air entering the annular cover 10 can trigger the trigger switch 22 faster, thereby accelerating the operation of the electric cylinder 23 to extend and push the sealing plate 16 to block the air inlet of the extension pipe 12, and avoiding more external air from entering the annular cover 10.

[0026] As shown in Figures 1-5 As a preferred embodiment of the present application, the discharge pipe 7 is coaxially arranged with the storage tank 1, and the bottom plate and the porous fluidization plate 11 of the storage tank 1 are designed as a taper, and the radius of the bottom plate and the porous fluidization plate 11 increases upward along the axis direction of the storage tank 1.

[0027] In actual application, the bottom plate and the porous fluidization plate 11 of the storage tank 1 are designed as a taper, and the radius of the bottom plate and the porous fluidization plate 11 increases upward along the axis direction of the storage tank 1. In the process of discharging sodium bicarbonate powder, the taper design can guide the sodium bicarbonate powder to naturally gather at the discharge pipe 7, so that the discharging process is more smooth and efficient. From the drying effect, when the hot gas is blown in, the sodium bicarbonate powder is blown up to realize the drying function. The sodium bicarbonate powder floats and rolls upward along with the upward airflow. The taper-shaped porous fluidization plate 11 plays a key role in guiding the sodium bicarbonate powder to flow to the middle. The powder continuously contacts and collides in the air in this process, increasing the contact area and frequency between the powder and the hot air. More contact means more complete heat exchange, so that the drying effect is significantly improved, and the moisture in the sodium bicarbonate powder can be more effectively removed.

[0028] As shown in Figure-1 Figure 5 As a preferred embodiment of the present application, the top plate of the storage tank 1 is rotatably installed with a feeding auger 24, and the feeding auger 24 is driven to rotate by a driving source.

[0029] In one case of the present embodiment, the driving source can be selected from a servo motor, a servo motor and other mechanisms capable of realizing rotary motion. The present embodiment does not make specific limitations here.

[0030] In actual application, the feeding auger 24 is arranged in the middle of the storage tank 1. When the hot gas is sprayed from the porous fluidization plate 11 to dry the sodium bicarbonate powder, the driving source drives the feeding auger 24 to rotate. In the initial stage of drying, the powder is accumulated on the bottom plate of the storage tank 1. The feeding auger 24 can stir the accumulated powder, thereby improving the heat exchange efficiency and the drying effect.

[0031] As shown in Figures 1-5 As a preferred embodiment of the present application, the feeding auger 24 extends into the discharge pipe 7, and the edge of the feeding auger 24 is in sliding fit with the inner wall of the discharge pipe 7.

[0032] In actual application, due to the conical design of the bottom plate of the storage tank 1 and the porous fluidization plate 11, the powder is accumulated in the middle of the storage tank 1, that is, the powder is easily accumulated around the feeding auger 24. Therefore, in the drying stage, the feeding auger 24 is driven by the driving source to rotate reversely, so as to continuously stir the sodium bicarbonate powder accumulated around the feeding auger 24 to the top of the discharge pipe 7. This makes the powder that is not fully dried due to accumulation fully exposed to the hot air flow, greatly increases the contact area and contact time of the powder and the hot air, and significantly improves the drying effect. In the discharging stage, the feeding auger 24 is driven by the driving source to rotate forwardly, and the sodium bicarbonate powder is pushed out of the discharge pipe 7 by the cooperation of the edge of the feeding auger 24 and the inner wall of the discharge pipe 7, thereby assisting the discharging and effectively avoiding the problems of poor discharging and even blockage caused by powder accumulation, ensuring smooth discharging process and maintaining efficient and stable operation of the production process.

[0033] As shown in Figures 1-5 As a preferred embodiment of the present application, the discharge end of the discharge pipe 7 is communicated with the conveying pipe 8, and the input end of the conveying pipe 8 is connected with the fan 9.

[0034] In one case of the present embodiment, it should be noted that the fan 9 of the present application is a prior art, and the present application does not improve it. Therefore, its specific mechanical structure and circuit structure do not need to be disclosed, and it does not affect the integrity of the present application.

[0035] In actual application, the sodium bicarbonate powder discharged from the discharge pipe 7 falls into the conveying pipe 8. At this time, the fan 9 is started to convey the sodium bicarbonate powder falling into the conveying pipe 8 to the place where it needs to be conveyed by wind power. The wind power conveying has the characteristics of fast speed, which can deliver the sodium bicarbonate powder to the destination in a short time, realizes the rapid transfer of the material, and greatly saves the conveying time.

[0036] The above has been described in detail one embodiment of the present application, but the content is only the preferred embodiment of the present application, cannot be considered for limiting the scope of the present application. Any equivalent changes and improvements made in the scope of the present application, should still belong to the scope of the present application.
