Description

Technical Field

[0001] The present invention belongs to the technical field of denitration, and particularly relates to a denitration reaction device for denitration. Background Art

[0002] The process of removing nitrogen oxides from combustion flue gas and the importance of preventing environmental pollution have been sharply raised as a worldwide issue. The relatively mainstream processes in the world are divided into: SCR and SNCR. Except that the reaction temperature of SCR is lower than that of SNCR due to the use of a catalyst, there is not much difference between the two processes. However, if viewed from the perspectives of construction cost and operating cost, the investment in SCR is at least several times, even more than 10 times that of SNCR; When the current denitration device is performing denitration work, due to the large amount of combustion flue gas, the denitration agent cannot completely denitrate the combustion flue gas, resulting in a poor denitration effect. Moreover, due to the large amount of combustion flue gas, the spraying nozzles for spraying the denitration agent are often blocked, resulting in a reduction in the efficiency of the denitration work, which is very inconvenient. Therefore, we have proposed a denitration reaction device for denitration. Summary of the Invention

[0003] The purpose of the present invention is to provide a denitration reaction device for denitration, which solves the existing problems through an equalizing mechanism.

[0004] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is a denitration reaction device for denitration, including an equalizing mechanism and a connecting pipe. The connecting pipes are respectively arranged at the upper and lower ends of the equalizing mechanism; The inside of the equalizing mechanism includes a cylindrical block, a first fixing block, a right-angle rod, and a spraying mechanism. The first fixing block is arranged at the central axis of the lower end inside the cylindrical block. The right-angle rods are arranged directly above the first fixing block. The spraying mechanism is arranged directly above the right-angle rods; The inside of the first fixing block includes a heat insulation plate, a U-shaped groove, a motor, a rotating rod, and a trapezoidal block.

The top of the rotating rod penetrates through the heat insulation plate and the first fixing block and extends to the outside. The top of the rotating rod penetrates through the bottom of the trapezoidal block and extends to the outside. The heat insulation plate can block most of the heat of the flue gas and also avoid the situation that the motor is affected by too high temperature.

[0005] The right-angle rods are all annularly and fixedly connected to the upper left and right ends of the outer surface of the rotating rod. A coolant is arranged inside the U-shaped groove, and the coolant can secondly prevent the motor from overheating due to the burning smoke.

The cylindrical rod is rotatably connected inside the concave block. A cylinder is fixedly installed on the outer surface of the cylindrical rod. Hard bristles are arranged on the outer surface of the cylinder. A T-shaped block is fixedly installed on the right side of the inner wall of the concave block.

[0008] Furthermore, the spraying mechanism internally includes a fixing block II, a fixing block III, a support block, a fixing plate, and a square block II. The fixing block III is fixedly installed at the bottom of the fixing block II. The support blocks are fixedly installed at the left and right ends of the inner wall bottom of the fixing block II. The fixing plate is slidably connected inside the fixing block II. The tops of the two support blocks are in contact with the bottom of the fixing plate. The square blocks II are fixedly installed on the left and right sides of the inner wall top of the fixing block II.

[0009] Furthermore, the fixing block III internally includes a square block III, a sliding plate, an elastic plate, a pushing block, a connecting rod, and a stress block. The middle axis of the square block III is fixedly installed at the middle axis of the fixing block III. Chutes are opened at the upper and lower ends on the left and right sides inside the fixing block III. The sliding plates are slidably connected to the ends of the four chutes close to each other. The elastic plates are fixedly connected to the upper and lower ends of the sides of the two sliding plates close to each other. The pushing blocks are fixedly connected to the ends of the four elastic plates close to each other. The connecting rods are fixedly connected to the ends of the two sliding plates away from each other. The stress blocks are fixedly installed at the ends of the two connecting rods away from each other.

[0010] Furthermore, the interior of the square block 2 includes an arc-shaped connecting block, a closing plate, a triangular block, a clamping block, an arc-shaped rod 2 and a filter screen. An opening is provided on the right side of the square block 2, and a water inlet is provided on the left side of the opening. The arc-shaped connecting blocks are fixedly connected to the upper and lower ends of the left inner wall of the opening, and the closing plates are rotatably connected to one end of the two arc-shaped connecting blocks close to each other. The triangular blocks are fixedly installed on the left sides of the two closing plates. Arc-shaped grooves are provided on the upper and lower ends of the inner wall of the opening, and the clamping blocks are slidably connected inside the two arc-shaped grooves. The arc-shaped rod 2 is fixedly connected to one end of the two clamping blocks close to each other, and the filter screen is provided on the right side of the square block 2.

[0011] Furthermore, one end of the two arc-shaped rods away from the two clamping blocks is fixedly connected to the right sides of the two closing plates.

[0012] The present invention has the following beneficial effects: The present invention uses an equal distribution mechanism. When the burning smoke enters the cylindrical block through the connecting pipe located at the bottom, the burning smoke will be dispersed to the surroundings of the cylindrical block through the fixed block. Then the motor is started and the two right-angle rods are driven to rotate through the rotating rod. When the two right-angle rods rotate, the circular rotating plate located on the four fixed rods will also rotate a small amount, thereby achieving the effect of evenly dispersing the burning smoke, thereby avoiding the situation that the denitrification agent will have a poor denitrification effect due to excessive combustion smoke emission, and also indirectly increases the denitrification efficiency.

[0013] The present invention uses a spraying mechanism. When the two right-angle rods drive the two arc blocks to rotate each time, the two rotating blocks will hit the two force-bearing blocks. The force on the two force-bearing blocks will drive the two sliding plates to move toward the inside of the fixed block three. The two push blocks will also move due to the push of the two sliding plates, and at the same time push the air inside the fixed block three. The air will be squeezed and flow out through the one-way air valve one at the central axis of the inner wall of the fixed block three. When the two force-bearing blocks are no longer under force, the two push blocks will return to their original positions through the two sliding plates due to the small springs. Since the two push blocks push the air of the fixed block three into the fixed block two, a negative pressure state will be generated when the two push blocks return to their positions, thereby sucking external air into the fixed block three through the one-way air valve two at the bottom of the fixed block three, achieving the effect of continuously conveying air to the inside of the fixed block two, so that the denitrification agent in the fixed block two can be sprayed to the outside, which increases the denitrification effect to a certain extent and avoids the need to manually denitrify the combustion flue gas.

[0014] In the present invention, through the square block II, at this time, since the air at the bottom of the fixing plate gradually increases, the fixing plate will move upward due to the air pressure and push the denitrating agent located in the fixing block II. The denitrating agent is extruded and enters the interior of the square block II through the two water inlets. As the denitrating agent increases, the two water inlets will be filled with the denitrating agent. At this time, both closing plates will be subjected to the extrusion force of the denitrating agent and rotate outward through the arc-shaped connecting blocks, thereby opening an opening so that the denitrating agent can be sprayed to denitrate the combustion flue gas, avoiding the situation that combustion flue gas enters the interior without spraying, and thus causing blockage due to a large amount of impurities in the flue gas.

[0015] In the present invention, through the filter screen, it can greatly avoid impurities in the flue gas from entering the interior of the square block II. The hard bristles on the outer surface of the cylinder at the top of the two right-angle rods will also continuously clean the filter screen. Every time the right-angle rods rotate to a certain position, they will clean the filter screen once to avoid blockage of the filter screen due to impurities in the flue gas.

[0016] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0022] Please refer to Figures 1-5 As shown, the present invention is a denitration reaction device for denitration, including an average distribution mechanism 1 and a connecting pipe 2, and is characterized in that: the connecting pipes 2 are respectively arranged at the upper and lower ends of the average distribution mechanism 1; The inside of the average distribution mechanism 1 includes a cylindrical block 11, a first fixed block 12, a right-angle rod 13 and a spraying mechanism 14. The first fixed block 12 is arranged at the central axis of the lower end inside the cylindrical block 11. The right-angle rods 13 are all arranged directly above the first fixed block 12. The spraying mechanism 14 is arranged directly above the right-angle rods 13. Through the average distribution mechanism 1, when the combusted flue gas enters the inside of the cylindrical block 11 through the connecting pipe 2 at the bottom, the combusted flue gas will be dispersed to the periphery inside the cylindrical block 11 through the first fixed block 12. Then, start the motor a3 and drive the two right-angle rods 13 to rotate through the rotating rod a4. When the two right-angle rods 13 rotate, the circular rotating plates 133 on the four first fixed rods 132 will also rotate slightly, so as to achieve the effect of evenly dispersing the combusted flue gas, thereby avoiding the situation that the denitration agent has poor denitration effect due to excessive discharge of the combusted flue gas, and also increasing the denitration efficiency indirectly; The first fixing block 12 internally includes a heat insulation plate a1, a U-shaped groove a2, a motor a3, a rotating rod a4, and a trapezoidal block a5. The heat insulation plate a1 is fixedly installed inside the first fixing block 12. The U-shaped groove a2 is arranged at the lower end of the inner surface of the heat insulation plate a1. The motor a3 is arranged on the inner surface of the U-shaped groove a2. The rotating rod a4 is rotatably connected to the top output end of the motor a3. The trapezoidal block a5 is fixedly connected to the top of the first fixing block 12. The top of the rotating rod a4 penetrates through the heat insulation plate a1 and the first fixing block 12 and extends to the outside. The top of the rotating rod a4 penetrates through the bottom of the trapezoidal block a5 and extends to the outside; The right-angle rods 13 are fixedly connected to the upper left and right ends of the outer surface of the rotating rod a4 in a circular shape. The U-shaped groove a2 is internally provided with coolant.

[0023] On the lower ends of the sides where the two right-angle rods 13 are close to each other, an arc-shaped block 131 is fixedly installed. On the left and right sides of the upper ends of the two right-angle rods 13, a first fixing rod 132 is fixedly installed. At the mutually distant ends of the four first fixing rods 132, a circular rotating plate 133 is rotatably connected. At the mutually close ends of the tops of the two right-angle rods 13, a support rod 134 is fixedly installed.

[0024] On the upper and lower ends of the left side of the support rod 134, a limit block q1 is fixedly connected. At the mutually distant ends of the two limit blocks q1, an arc-shaped rod q2 is fixedly connected. On the left side of the support rod 134, a square block q3 is fixedly installed. On the left side of the square block q3, a concave block q4 is embedded. Inside the concave block q4, there is a vertical cylindrical rod q5. The cylindrical rod q5 is rotatably connected inside the concave block q4. On the outer surface of the cylindrical rod q5, a cylinder q6 is fixedly installed. Hard bristles are arranged on the outer surface of the cylinder q6. On the right side of the inner wall of the concave block q4, a T-shaped block is fixedly installed.

[0025] The spraying mechanism 14 internally includes a second fixing block s1, a third fixing block s2, a support block s3, a fixing plate s4, and a second square block s5. The third fixing block s2 is fixedly installed at the bottom of the second fixing block s1. The support blocks s3 are fixedly installed at the left and right ends of the bottom of the inner wall of the second fixing block s1. The fixing plate s4 is slidably connected inside the second fixing block s1. The tops of the two support blocks s3 are in contact with the bottom of the fixing plate s4. The second square blocks s5 are fixedly installed on the left and right sides of the top of the inner wall of the second fixing block s1. Through the second square blocks s5, at this time, as the air at the bottom of the fixing plate s4 gradually increases, the fixing plate s4 will move upward due to the air pressure and push the denitration agent located in the second fixing block s1. The denitration agent is extruded and enters the inside of the second square blocks s5 through the two water inlets. As the denitration agent increases, the two water inlets will be filled with the denitration agent. At this time, both closing plates s52 will be pushed by the extrusion force of the denitration agent and rotate outward through the arc-shaped connecting block a51, thereby opening an opening so that the denitration agent can be sprayed to denitrate the combustion flue gas, avoiding the situation that combustion flue gas enters the inside without spraying, resulting in blockage due to a large amount of impurities in the flue gas.

[0026] Inside the third fixed block s2, there are a third square block s21, a sliding plate s22, an elastic plate s23, a pushing block s24, a connecting rod s25 and a stress block s26. The middle axis of the third square block s21 is fixedly installed at the middle axis inside the third fixed block s2. Chutes are provided at the upper and lower ends on the left and right sides inside the third fixed block s2. The sliding plates s22 are all slidably connected to one end where the four chutes are close to each other. The elastic plates s23 are fixedly connected to the upper and lower ends on one side where the two sliding plates s22 are close to each other. The pushing blocks s24 are fixedly connected to one end where the four elastic plates a23 are close to each other. The connecting rods s25 are fixedly connected to one end where the two sliding plates s25 are away from each other. The stress blocks s26 are fixedly installed at one end where the two connecting rods s25 are away from each other. Through the spraying mechanism 14, every time the two right-angle rods 13 drive the two arc-shaped blocks 131 to rotate, the two rotating blocks 131 will both strike the two stress blocks s26. The two stress blocks s26 will drive the two sliding plates s22 to move towards the inside of the third fixed block s2 under force. The two pushing blocks s24 will also move accordingly due to the push of the two sliding plates s22, and at the same time push the air inside the third fixed block s2. The air is squeezed and will flow out through the one-way air valve one at the middle axis of the inner wall of the third fixed block s2. When the two stress blocks s26 are not under force, the two pushing blocks s22 will return to their original positions through the two sliding plates s23 because of the small springs. Since the two pushing blocks s22 push the air in the third fixed block s2 into the second fixed block s1, a negative pressure state will be generated when the two pushing blocks s22 return to their positions, so the outside air will be sucked into the inside of the third fixed block s2 through the one-way air valve two at the bottom of the third fixed block s2, achieving the effect of continuously transporting air into the second fixed block s1, so that the denitration agent inside the second fixed block s1 can be sprayed to the outside, increasing the denitration effect to a certain extent, and avoiding the need for manual denitration of the combustion flue gas.

[0027] The interior of the second square block s5 includes an arc-shaped connecting block s51, a closing plate s52, a triangular block s53, a clamping block s54, a second arc-shaped rod s55, and a filter screen s56. There is an opening on the right side of the second square block s5, and a water inlet is arranged on the left side of the opening. The arc-shaped connecting blocks s51 are fixedly connected to the upper and lower ends on the left side of the inner wall of the opening. The closing plates s52 are rotatably connected to one end of the two arc-shaped connecting blocks s51 close to each other. The triangular blocks s53 are fixedly installed on the left sides of the two closing plates s52. Arc-shaped grooves are formed in the upper and lower ends of the inner wall of the opening. The clamping blocks s54 are slidably connected to the inside of the two arc-shaped grooves. The second arc-shaped rods s55 are fixedly connected to one end of the two clamping blocks s54 close to each other. The filter screen s56 is arranged on the right side of the second square block s5. Through the filter screen s56, impurities in the flue gas can be greatly avoided from entering the interior of the second square block s5. The hard bristles on the outer surface of the cylinder q6 located at the top of the two right-angle rods 13 will also continuously clean the filter screen s56. Every time the right-angle rod 13 rotates to a certain position, the filter screen s56 will be cleaned once to prevent the filter screen s56 from being blocked due to impurities in the flue gas.

[0028] One end of the two second arc-shaped rods s55 far from the two clamping blocks s54 is fixedly connected to the right sides of the two closing plates s52.

[0029] A specific application of this embodiment is as follows: When the burning flue gas enters the inside of the cylindrical block 11 through the connecting pipe 2 located at the bottom, the burning flue gas will be dispersed to the periphery inside the cylindrical block 11 through the first fixing block 12. Then, start the motor a3 and drive the two right-angle rods 13 to rotate through the rotating rod a4. When the two right-angle rods 13 drive the two arc-shaped blocks 131 to rotate each time, the two rotating blocks 131 will strike the two force-receiving blocks s26. The two force-receiving blocks s26 will drive the two sliding plates s22 to move towards the inside of the third fixing block s2 under the action of force. The two pushing blocks s24 will also move accordingly due to the pushing of the two sliding plates s22, and at the same time, push the air inside the third fixing block s2. The air is squeezed and will flow out through the one-way air valve one at the central axis of the inner wall of the third fixing block s2. When the two force-receiving blocks s26 are no longer under force, the two pushing blocks s22 will return to their original positions through the two sliding plates s23 due to the small springs. Since the two pushing blocks s22 push the air in the third fixing block s2 into the second fixing block s1, a negative pressure state will be generated when the two pushing blocks s22 return to their positions, so that the external air will be sucked into the inside of the third fixing block s2 through the one-way air valve two at the bottom of the third fixing block s2. At this time, the fixing plate s4 will move upward due to the increasing air pressure at the bottom and push the denitrating agent in the second fixing block s1. The denitrating agent is squeezed and enters the inside of the second square block s5 through the two water inlets. As the denitrating agent increases, the two water inlets will be filled with the denitrating agent. At this time, the two closing plates s52 will be rotated outward through the arc-shaped connecting block a51 under the squeezing force of the denitrating agent, so as to open an opening to allow the denitrating agent to be sprayed out for denitrification of the burning flue gas. When the two right-angle rods 13 rotate, the circular rotating plates 133 on the four first fixing rods 132 will also rotate slightly, so as to achieve the effect of evenly dispersing the burning flue gas. The hard bristles on the outer surface of the cylinder q6 at the top of the two right-angle rods 13 will always clean the filter screen s56.
