Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flue gas pollutant treatment, in particular to a denitration agent pyrolysis furnace conveying system. BACKGROUND

[0002] In the field of flue gas treatment of fixed pollution sources such as coal-fired power plants and industrial boilers, the selective catalytic reduction denitration technology is selected as the core means for controlling nitrogen oxide emissions, and the stability of the denitration agent supply system is directly related to the operation efficiency of the environmental protection facilities. During the storage and conveying of solid denitration agent, the moisture absorption and crystallization phenomenon is prone to occur due to the influence of environmental temperature and humidity fluctuations. When the environmental temperature is lower than the critical moisture absorption point of the material, a micron-level liquid film will be formed on the surface of the denitration agent particles, causing crystal reconstruction and secondary polymerization; and under the condition that the relative humidity is greater than 60%, the capillary action between the material layers is intensified, causing hard bridging between the particles, and finally causing the hardening and caking.

[0003] In the related art, passive moisture-proof measures such as electric heat tracing and silica gel desiccant are often used, but there are defects such as high energy consumption (electric heat tracing power reaches 25-40 W / m) and high maintenance frequency (the desiccant needs to be replaced every week). SUMMARY

[0004] The present application aims to at least partially solve one of the technical problems in the related art.

[0005] To this end, an embodiment of the present application proposes a denitration agent pyrolysis furnace conveying system, which can effectively solve the problem of denitration agent hardening and caking, and has the advantages of high reliability and good economy.

[0006] The denitration agent pyrolysis furnace conveying system according to an embodiment of the present application comprises:

[0007] A storage assembly, the storage assembly comprising a storage part and a conveying part, the storage part having a storage inlet and a storage outlet, the storage inlet being configured to pass in denitration agent, the first end of the conveying part being adjacent to the storage outlet for conveying the denitration agent discharged from the storage outlet;

[0008] A crushing assembly, the crushing assembly comprising a crushing tank body and a crushing piece, the inlet of the crushing tank body being connected to the second end of the conveying part for receiving the denitration agent conveyed by the conveying part, the outlet of the crushing tank body being connected to a flue gas treatment device for conveying the denitration agent in the crushing tank body to the flue gas treatment device, the crushing piece being disposed in the chamber of the crushing tank body, the crushing tank body being rotatable about the extension direction of the central axis thereof, the inner peripheral wall of the crushing tank body being provided with a plurality of grooves, the crushing piece being adapted to the grooves, wherein the extension direction of the central axis of the crushing tank body is parallel to the horizontal direction.

[0009] The crushing assembly of the denitrification agent pyrolysis furnace conveying system of the embodiment of the present invention can effectively deal with the possible compaction and agglomeration of the denitrification agent. When compacted denitrification agent enters the crushing tank body, the rotatable crushing tank body rotates around its horizontal central axis, and cooperates with the crushing parts placed in the chamber and adapted to the grooves on the inner wall of the tank body to crush the compacted denitrification agent. The rotation of the crushing tank body causes the denitrification agent to continuously roll inside the tank body, which increases the contact opportunities between the crushing parts and the denitrification agent, improves the crushing effect, and re-crushes the compacted denitrification agent into a granular state suitable for use, ensuring that the denitrification agent can be smoothly transported to the flue gas treatment equipment to play its role.

[0010] In some embodiments, there are a plurality of the crushing pieces, and the number of the plurality of the crushing pieces is greater than the number of the plurality of the grooves.

[0011] In some embodiments, the plurality of grooves are divided into a first groove group and a second groove group, and the first groove group and the second groove group are symmetrically arranged in a circumferential direction of a central axis of the crushing tank body.

[0012] In some embodiments, the groove is an arc-shaped groove, and the crushing member is a sphere.

[0013] In some embodiments, the maximum depth of the groove is smaller than the radius of the crushing element.

[0014] In some embodiments, the depth of the groove gradually increases in a direction from the bottom of the crushing can to the top of the crushing can.

[0015] In some embodiments, the crushing element has a spherical cavity therein, and the center of the spherical cavity is spaced apart from the center of the crushing element.

[0016] In some embodiments, the crushing tank body also has a flue gas inlet and a flue gas outlet. The flue gas inlet is used to allow flue gas to enter. In the crushing tank body, the denitrification agent and the flue gas are pyrolyzed to produce ammonia and mixed with the flue gas. The flue gas outlet is used to be connected to the flue.

[0017] In some embodiments, the denitrification agent pyrolysis furnace delivery system of the embodiment of the present invention further includes a mixing element, which is connected between the flue gas outlet and the flue, and is used to mix the mixed gas discharged from the flue gas outlet.

[0018] In some embodiments, the material storage assembly further includes a metering portion, which is connected between the material storage outlet and the first end of the conveying portion. The metering portion is used to record the amount of denitrification agent discharged from the material storage portion and control the opening and closing degree of the material storage outlet according to the amount of denitrification agent discharged.

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] like Figure 1-Figure 3 As shown, the denitrification agent pyrolysis furnace conveying system of the embodiment of the present invention includes a storage component 1 and a crushing component 2.

[0029] The storage assembly 1 includes a storage portion 11 and a conveying portion 12. The storage portion 11 has a storage inlet and a storage outlet. The storage inlet is used to introduce denitrification agent. The first end of the conveying portion 12 is adjacent to the storage outlet for conveying the denitrification agent discharged from the storage outlet. The crushing assembly 2 includes a crushing tank 21 and a crushing component 22. The inlet of the crushing tank 21 is connected to the second end of the conveying portion 12 for receiving the denitrification agent conveyed by the conveying portion 12. The outlet of the crushing tank 21 is connected to the flue gas treatment equipment for conveying the denitrification agent in the crushing tank 21 to the flue gas treatment equipment. The crushing component 22 is placed in the chamber of the crushing tank 21. The crushing tank 21 is rotatable around the extension direction of its central axis. The inner peripheral wall of the crushing tank 21 is provided with a plurality of grooves 211. The crushing component 22 is adapted to the grooves 211, wherein the extension direction of the central axis of the crushing tank 21 is parallel to the horizontal direction.

[0030] Specifically, if Figure 1 and Figure 2As described above, the storage section 11 provides storage space for the denitrifier, which can meet the usage demand within a certain period of time, avoid frequent addition of denitrifier, and ensure the continuity of denitrification. The conveying section 12 serves as a transition component between the storage section 11 and the subsequent crushing assembly 2, ensuring that the denitrifier can be smoothly transported from the storage section 11 to the crushing assembly 2, playing the role of connection and conveyance.

[0031] The first end of the conveying part 12 receives the denitrification agent discharged from the storage outlet, and conveys it to the second end of the conveying part 12 and then enters the crushing tank body 21. The rotation of the crushing tank body 21 can drive the denitrification agent and the crushing part 22 in the crushing tank body 21 to rotate, and because the crushing part 22 can fit in the groove 211, the crushing part 22 can rotate with the crushing tank body 21 to a certain height and separate from the groove 211, so that it hits the denitrification agent under the action of gravity, thereby realizing the crushing function.

[0032] That is, when the denitrification agent in the crushing tank 21 becomes compacted, the rotatable crushing tank 21 rotates around its horizontal center axis, causing the denitrification agent to continuously tumble within the tank. This causes the compacted denitrification agent to break up under the action of gravity and the rotation of the crushing tank 21. The rotation of the crushing tank 21 increases the contact opportunity between the crushing element 22 and the denitrification agent. The crushing element 22 fits into the groove 211 on the inner wall of the tank. During the rotation of the tank, the crushing element 22 and the groove 211 work together, causing the crushing element 22 to move to a higher position in the crushing tank 21 and fall down to break up the compacted denitrification agent, breaking it back into particles suitable for use.

[0033] Therefore, the crushed denitrification agent can be smoothly transported to the flue gas treatment equipment through the outlet of the crushing tank 21, ensuring that the denitrification agent can function normally, improving the stability of the denitrification agent supply system, and thus ensuring the operating efficiency of the environmental protection facilities.

[0034] In other words, the crushing component 2 of the denitrification agent pyrolysis furnace conveying system of the embodiment of the present invention can effectively deal with the possible compaction and agglomeration of the denitrification agent. When the compacted denitrification agent enters the crushing tank body 21, the rotatable crushing tank body 21 rotates around its horizontal central axis, and cooperates with the crushing parts 22 placed in the chamber and adapted to the groove 211 on the inner wall of the tank body to crush the compacted denitrification agent. The rotation of the crushing tank body 21 causes the denitrification agent to continuously roll inside the tank body, which increases the contact opportunity between the crushing parts 22 and the denitrification agent, improves the crushing effect, and re-crushes the compacted denitrification agent into a granular state suitable for use, ensuring that the denitrification agent can be smoothly transported to the flue gas treatment equipment to play its role.

[0035] In some embodiments, there are multiple crushing parts 22, and the number of the multiple crushing parts 22 is greater than the number of the multiple grooves 211. It can be understood that a larger number of crushing parts 22 means that during the rotation of the crushing tank 21, there will be more crushing points that come into contact with the compacted denitrifier. Each crushing part 22 can apply crushing force to the compacted denitrifier. When multiple crushing parts 22 act at the same time, the denitrifier can be crushed over a larger range, thereby improving the comprehensiveness of the crushing. Since the degree and shape of the compaction of the denitrifier may vary, more crushing parts 22 can act on it from different angles and positions, effectively avoiding the situation where certain parts of the denitrifier cannot be fully crushed due to lack of crushing action.

[0036] In addition, the compaction of the denitrification agent may be more complicated, some may be more severely compacted, and some may only be partially compacted. A large number of crushing parts 22 can be used for targeted crushing according to different compaction conditions. For heavier compacted parts, multiple crushing parts 22 may be required to work together to effectively crush them; and for local compaction, multiple crushing parts 22 can also process these local areas more accurately to ensure the consistency of the crushing effect. In some embodiments, the multiple grooves 211 are divided into a first groove group 212 and a second groove group 213, and the first groove group 212 and the second groove group 213 are symmetrically arranged in the circumferential direction of the central axis of the crushing tank body 21.

[0037] In some embodiments, the groove 211 is an arc-shaped groove, and the crushing element 22 is a sphere. It is understood that spheres have excellent rolling properties. When the crushing tank 21 rotates about its horizontal central axis, the spheres roll within the tank, following the tumbling of the denitrifying agent. This rolling motion enables the spheres to contact compacted denitrifying agent at various angles and directions. Compared to the regular, fixed crushing element 22, the spheres can more flexibly adapt to the various shapes and compacted states of the denitrifying agent, achieving comprehensive crushing of the denitrifying agent.

[0038] The shape of the arc groove is adapted to the ball, and when the ball rolls into the arc groove, the two can form an effective squeezing and shearing effect. Moreover, as the ball rolls in the arc groove, its contact point with the arc groove will continuously change, further increasing the flexibility and diversity of the crushing process, helping to more thoroughly break up the compacted denitrification agent.

[0039] In some embodiments, the maximum depth of the groove 211 is less than the radius of the crushing element 22. It will be appreciated that when the maximum depth of the groove 211 is less than the radius of the crushing element 22, the crushing element 22 (e.g., a sphere) will not be completely sunken into the groove 211. During the rotation of the crushing tank 21, the crushing element 22 can roll and move freely within the tank, without becoming stuck due to excessively deep grooves 211, thereby ensuring smooth movement of the crushing element 22. This allows the crushing element 22 to continuously engage with the compacted denitrifier and perform the crushing operation, maintaining the continuity of the crushing process.

[0040] Furthermore, since the crushing element 22 is not restricted by the depth of the groove 211, it can more easily change its direction of movement during the rolling process according to the tumbling of the denitrifying agent in the tank and its own stress state. This allows the crushing element 22 to more comprehensively cover the denitrifying agent in the tank, increasing the contact opportunity with the denitrifying agent and improving the crushing effect.

[0041] In some embodiments, the depth of the groove 211 gradually increases in the direction from the bottom of the crushing tank 21 to the top of the crushing tank 21. It can be understood that Figure 1 and Figure 2 As shown, the groove 211 at the bottom of the crushing tank 21 is relatively shallow. As the crushing tank 21 rotates, the crushing elements 22 at the bottom, affected by the accumulation of denitrifying agent and gravity, are not trapped in the groove 211 and can roll more freely within the denitrifying layer. This allows the crushing elements 22 to frequently come into contact with the large amount of accumulated denitrifying agent at the bottom, increasing the chances of crushing the denitrifying agent at the bottom and improving the denitrifying effect at the bottom.

[0042] That is, the depth of the grooves 211 gradually increases toward the top of the tank, allowing some crushing elements 22 to fit within the deeper grooves 211 and move to higher positions as the crushing tank 21 rotates. When the crushing elements 22 roll to the top of the tank, the deeper grooves 211 guide them deeper into contact with the compacted denitrifier. The denitrifier at the top will tumble somewhat during the tank's rotation, and the deeper grooves 211 allow the crushing elements 22 to move to a higher position and fall, effectively crushing the denitrifier at the bottom of the crushing tank 21 and ensuring that the denitrifier is fully crushed throughout the tank.

[0043] In some embodiments, the crushing element 22 has a spherical chamber 221 therein, and the center of the spherical chamber 221 is spaced apart from the center of the crushing element 22 .

[0044] It is understandable that if Figure 3As shown, due to the center of the spherical chamber 221 does not coincide with the center of the crushing piece 22, the center of gravity of the crushing piece 22 is offset. When the crushing tank 21 rotates, the crushing piece 22 will produce irregular motion due to the offset of the center of gravity. It is no longer a simple regular rolling, but will move in a more complex trajectory in the tank, including shaking, jumping, etc. This irregular motion greatly increases the contact angle and mode of the crushing piece 22 and the agglomerated denitration agent, making the crushing process more random and diversified.

[0045] In addition, the irregular motion of the crushing piece 22 can exert crushing force on the agglomerated denitration agent from different directions and angles, in addition to the common extrusion and shearing action, it can also produce different forms of crushing action such as twisting and impact. These diversified crushing actions can more effectively deal with denitration agents of different shapes and degrees of agglomeration, improving the crushing effect.

[0046] In some embodiments, the crushing tank 21 also has a flue gas inlet and a flue gas outlet, the flue gas inlet is used to pass in flue gas, and in the crushing tank 21, the denitration agent is pyrolyzed to produce ammonia gas and mixed with the flue gas, and the flue gas outlet is used to connect with the flue 100.

[0047] As can be understood, Figure 1 and Figure 2 As shown, when the flue gas enters the crushing tank 21 through the flue gas inlet, it provides the heat and environment required for the pyrolysis of the denitration agent. The denitration agent will undergo a pyrolysis reaction when it comes into contact with the high-temperature flue gas in the crushing tank 21, producing ammonia gas. The direct pyrolysis in the crushing tank 21 makes full use of the heat of the flue gas, without the need for additional heating equipment, reducing energy consumption and equipment cost.

[0048] The rotation of the crushing tank 21 causes the denitration agent to constantly tumble in the tank, increasing the contact area and contact time of the denitration agent with the flue gas. It is beneficial to improve the efficiency of the pyrolysis reaction, so that more denitration agent can be quickly and fully pyrolyzed to generate ammonia gas, providing sufficient ammonia gas source for the subsequent denitration process.

[0049] In some embodiments, the denitration agent pyrolysis furnace conveying system of the embodiments of the present application further comprises a mixing piece 3 connected between the flue gas outlet and the flue 100, the mixing piece 3 is used to mix the mixed gas discharged from the flue gas outlet.

[0050] As can be understood, Figure 1 and Figure 2 As shown, the ammonia gas and flue gas produced by the pyrolysis of the denitration agent in the crushing tank 21 have been preliminarily mixed, but there may still be a situation where the mixing is not uniform enough. The mixing piece 3 can perform secondary mixing on the mixed gas discharged from the flue gas outlet, and through its special structure or mixing mechanism, the ammonia gas and flue gas can be more fully intermingled.

[0051] Further mixing in the mixing element 3 effectively eliminates any localized excess or excess concentration of ammonia in the mixed gas. A uniform mixed gas composition helps ensure ammonia and nitrogen oxides react more precisely in a stoichiometric ratio during the subsequent denitration reaction in the flue 100, improving denitration efficiency.

[0052] In some embodiments, the material storage assembly 1 further includes a metering portion 13, which is connected between the material storage outlet and the first end of the conveying portion 12. The metering portion 13 is used to record the amount of denitrification agent discharged from the material storage portion 11 and control the opening and closing degree of the material storage outlet according to the amount of denitrification agent discharged.

[0053] It is understood that the metering unit 13 can accurately record the amount of denitrifier discharged from the storage unit 11 in real time. During the denitrification process, different operating conditions require different amounts of denitrifier. For example, changes in the concentration of nitrogen oxides in the flue gas and fluctuations in the flue gas flow rate can affect the amount of denitrifier used. Through real-time metering, the system can clearly understand the actual consumption of denitrifier.

[0054] Based on the recorded discharge volume, metering unit 13 precisely controls the opening and closing of the storage outlet. When a larger amount of denitrifier is needed, metering unit 13 increases the opening to allow more denitrifier to be discharged; when demand decreases, the opening is reduced to avoid wasting denitrifier. This precise control ensures that the supply of denitrifier matches actual demand during the denitrification process, improving denitrification efficiency.
