Description

Technical Field

[0001] The present application generally relates to the field of flue gas treatment technology, and specifically relates to a multi-effect organic amine mixing device and a SNCR denitrification system. Background Art

[0002] In the selective non-catalytic reduction (SNCR) denitrification process, multi-effect organic amines are a class of compounds with multiple functions, usually used as reducing agents or catalysts. They can effectively promote the reduction reaction of NOx (nitrogen oxides) and show good selectivity and efficiency in the reaction.

[0003] Typical representatives of multi-effect organic amines include some common organic compounds, such as ethylenediamine: a diamine compound that can react with NOx within a certain temperature range to produce nitrogen and water. Propylenediamine: also a diamine compound with a catalytic effect similar to ethylenediamine. Methylamine: a monoamine compound that can also act as a reducing agent in the denitrification reaction.

[0004] The mechanism of action of these multi-effect organic amines is to provide amino groups (-NH2) to selectively reduce nitrogen oxides in NOx to produce harmless nitrogen and water.

[0005] However, when multi-effect organic amines are mixed, the traditional mixing equipment has low mixing efficiency, resulting in insufficient catalyst concentration in some areas. This cannot effectively promote the reduction reaction of nitrogen oxides (NOx), thereby reducing the overall denitrification efficiency. The reaction temperature window is unevenly distributed, and some areas may be too cold or too hot, affecting the stability of the reaction. Some catalysts may be exposed to high temperature environments, accelerating the deactivation and loss of the catalyst. Summary of the invention

[0043] In order to make the purpose, scheme and advantages of the technical solution of the present application clearer, the technical solution of the embodiment of the present application will be clearly and completely described in conjunction with the drawings of the specific embodiments of the present application. Unless otherwise specified, the terms used herein have the usual meanings in the art. The same reference numerals in the drawings represent the same components.

[0044] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] As described above, in the traditional SNCR denitrification treatment, the uneven mixing of the multi-effect catalyst leads to insufficient catalyst concentration in some areas, which reduces the overall denitrification efficiency and accelerates the deactivation and loss of the catalyst.

[0046] See also Figure 1-Figure 10A multi-effect organic amine mixing device comprises: a tank body 1, a driving rod 2, the driving rod 2 is rotatably arranged in the axial direction of the tank body 1; and a driving part 3, which is arranged on the outer wall of one end of the tank body 1, and one end of the driving rod 2 passes through the end surface of the tank body 1 and is driven and connected to the driving part 3; a liquid inlet 4 is provided at one end of the tank body 1, and a liquid outlet 5 is provided at the other end; a rectifying plate 6, a circular hole 63 is provided in the center, and is sleeved on the circumferential outer wall of the driving part 3; a rectifying assembly 8 is provided on the surface of the rectifying plate 6; the rectifying plate 6 reciprocates on the surface of the driving rod 2; a limiting rod assembly 9 is provided on one side of the driving part 3 in the tank body 1, and the rectifying plate 6 slides along the surface of the limiting rod.

[0047] In use, the multi-effect organic amine solution plays an important role in the denitration process, and its mixing uniformity directly affects the denitration efficiency and the overall performance of the system. The multi-effect organic amine mixing device provided in this embodiment, when working, the liquid inlet 4 of the tank body 1 extracts ethanolamine, diethanolamine, and triethanolamine from multiple storage tanks, and the driving part 3 drives the driving rod 2 to rotate. When the driving rod 2 rotates, it drives the rectifier plate 6 to reciprocate on the surface of the driving rod 2. When the rectifier plate 6 moves in the tank body 1 along the length direction of the tank body 1, the extracted reducing agent enters from the bottom of the tank body 1. When the rectifier plate 6 moves downward, the reducing agent squeezed at the bottom of the tank body 1 moves upward through the rectifier plate 6, so that the reducing agent above and below the tank body 1 is continuously mixed through the rectifier plate 6. Compared with the traditional method in which the stirring shaft drives the stirring blades to rotate in the tank body 1, the traditional reducing agent can only be driven by the stirring blades to form a vortex in the tank body 1, and the reducing agent above and below the tank body 1 is not evenly mixed, so that when the nozzle extracts the reducing agent in the tank body 1 for spraying, the concentration of the reducing agent at each position in the tank body 1 is different, thereby affecting the efficiency of the denitrification reaction.

[0048] See also Figure 1-Figure 10 In some embodiments, the driving rod 2 includes: a rod-shaped body 21, two ends of which are respectively rotatably connected to the end walls of the tank body 1, one end of which passes through the end wall of the tank body 1 to connect to the driving part 3; a first guide groove 22 and a second guide groove 23; wherein the first guide groove 22 and the second guide groove 23 are both arranged on the circumferential outer wall of the rod-shaped body 21; the first guide groove 22 and the second guide groove 23 are connected end to end; wherein the first guide groove 22 is spirally arranged along the circumferential outer wall of the rod-shaped body 21, and the second guide groove 23 is spirally arranged along the circumferential outer wall of the rod-shaped body 21 The liquid outlet 5 is arranged in the length direction of the rod-shaped body 21; the liquid outlet 5 includes: a liquid outlet channel 51, which is arranged in the top end of the rod-shaped body 21, one end is arranged on the end surface of the rod-shaped body 21, and the other end is arranged on the circumferential outer wall of the rod-shaped body 21; the end of the liquid outlet channel 51 away from the tank body 1 is connected to the nozzle liquid inlet 4, including: a first liquid inlet pipe 41, a second liquid inlet pipe 42, and a solenoid valve 43; wherein the first liquid inlet pipe 41 and the second liquid inlet pipe 42 are arranged at the bottom end of the tank body 1, and the first liquid inlet pipe 41 and the second liquid inlet pipe 42 are respectively connected to the solenoid valve 43.

[0049] An annular groove 61 is also provided on the surface of the rectifier plate 6, and the annular groove 61 is concentrically arranged with the rectifier plate 6; a limit block 62 is provided in the circular hole 63 of the rectifier plate 6, and the limit block 62 is slidably arranged in the first guide groove 22 and the second guide groove 23; a rectifier component 8 is provided in the annular groove 61; the rectifier component 8 includes: two groups of impellers 81, one group of impellers 81 is arranged in the annular groove 61, and the other group of impellers 81 is arranged at intervals at the lower part of the rectifier plate 6 and is sleeved on the outer wall of the rod-shaped body 21; the two groups of impellers 81 rotate in opposite directions; a buffer component 82 is provided between the two groups of impellers 81.

[0050] During use, the rod-shaped body 21 is driven by the driving part 3 to rotate in the tank body 1. The rectifying plate 6 is limited by the limiting rod assembly 9, so that the rectifying plate 6 does not rotate. The limiting block 62 in the circular hole 63 of the rectifying plate 6 slides in the first guide groove 22 and the second guide groove 23, so that when the rod-shaped body 21 rotates, the rod-shaped body 21 drives the rectifying plate 6 to move along the length direction of the rod-shaped body 21 through the first guide groove 22. When the limiting block 62 slides into the second guide groove 23, the rectifying plate 6 moves in the opposite direction through the limiting rod assembly 9, so that the rectifying plate 6 pushes the reducing agent in the tank body 1 to continuously pass through the rectifying plate 6 for mixing;

[0051] A plurality of first liquid inlet pipes 41 and second liquid inlet pipes 42 may be provided, and the liquid inlet of the tank body 1 is controlled by the solenoid valve 43. The plurality of first liquid inlet pipes 41 and second liquid inlet pipes 42 are connected to the plurality of liquid storage tanks 111. After the mixing is completed, the reducing agent is discharged through the liquid outlet 5.

[0052] When the rectifier plate 6 is squeezed downward, it first passes through the impeller 81 located at the bottom, so that when the various reducing agents pass through the lower impeller 81, the reducing agents form a vortex under the rectifier plate 6, and then pass through the impeller 81 located at the rectifier plate 6. Since the two impellers 81 rotate in opposite directions, when the various reducing agents pass through the two impellers 81, the direction of the vortex changes, and the various reducing agents are mixed through the fixed impeller 81.

[0053] See also Figure 1-Figure 10 In some embodiments, the limit rod assembly 9 includes: two groups of sliding rods 91, which are respectively arranged on both sides of the rod-shaped body 21, and the two ends of the sliding rod 91 are respectively connected to the inner walls of the tank body 1; and a return spring 92, which is sleeved on the surface of the sliding rod 91 and arranged between the rectifying plate 6 and the inner bottom surface of the tank body 1; wherein two sliding holes 64 are provided on the surface of the rectifying plate 6, and the two groups of sliding rods 91 are slidably arranged in the two sliding holes 64.

[0054] During use, when the rod-shaped body 21 rotates, the rectifier plate 6 moves on the surface of the two groups of slide bars 91. The slide bars 91 are used to limit the rotation of the rectifier plate 6, so that when the rod-shaped body 21 rotates, the rectifier plate 6 can be driven to move up and down through the first guide groove 22. When the rectifier plate 6 gradually approaches the bottom end of the tank body 1, the rectifier plate 6 compresses the reset spring 92. When the limit block 62 of the rectifier plate 6 enters the second guide groove 23 from the first guide groove 22, the rectifier plate 6 is pushed by the reset spring 92, thereby moving the rectifier plate 6 upward. The reducing agent first moves from the lower part of the tank body 1 to the upper part, and then moves upward with the rectifier plate 6. The rectifier plate 6 squeezes the reducing agent that is initially mixed in the upper part of the tank body 1, so that the reducing agent after the initial mixing passes through the rectifier plate 6 again to the bottom of the tank body 1 for mixing.

[0055] See also Figure 1-Figure 10 In some embodiments, the driving unit 3 includes: a driving motor 31, which is arranged on the outer bottom surface of the tank body 1; a driving gear 32, which is arranged on the output shaft of the driving motor 31; and a driven gear 33, which is arranged at the bottom end of the rod-shaped body 21 and meshes with the driving gear 32.

[0056] In use, when the driving part 3 is working, the output shaft of the driving motor 31 drives the driving gear 32 to rotate, and the rotation of the driving gear 32 drives the driven gear 33 to rotate, thereby driving the rod-shaped body 21 to rotate through the driven gear 33 .

[0057] See also Figure 1-Figure 10 In some embodiments, the buffer assembly 82 includes: a first connecting block 821 and a second connecting block 822; the top end of the first connecting block 821 is connected to the impeller 81 in the annular groove 61, and the bottom end of the second connecting block 822 is connected to another impeller 81; a connecting rod 823, one end of which is connected to the bottom end of the first connecting block 821, and the other end points to the second connecting block 822; a mounting hole 824 is provided on the surface of the second connecting block 822, and one end of the connecting rod 823 away from the first connecting block 821 is slidably provided in the mounting hole 824; a spring 825 is provided between the first connecting block 821 and the second connecting block 822, and the spring 825 is sleeved on the circumferential outer wall of the rod-shaped body 21.

[0058] During use, when the rectifier plate 6 moves, the spring 825 pushes the other impeller 81 to move, so that multiple reducing agents can pass through the two impellers 81 one by one. When the impeller 81 located below abuts against the inner bottom surface of the tank body 1, the spring 825 contracts, and the rectifier plate 6 continues to move downward. Then the limit block 62 enters the second guide groove 23, and the rectifier plate 6 then moves in the opposite direction. The setting of the connecting rod 823 and the spring 825 can make the rectifier plate 6 as close to the inner bottom surface of the tank body 1 as possible, and try to avoid the reducing agent near the liquid inlet 4 of the tank body 1 from entering the upper part of the tank body 1 for mixing.

[0059] See also Figure 1-Figure 10In some embodiments, an emission assembly 10 is further provided on the surface of the rectifying plate 6, and the emission assembly 10 includes: a mounting ring 101, which is provided on the inner wall of the tank body 1 and is spaced apart on the upper part of the rectifying plate 6; a fan-shaped mounting plate 102, which is provided with two groups, and the two groups of fan-shaped mounting plates 102 are symmetrically provided on both sides of the circumferential outer wall of the rod-shaped body 21, and a movable hole 103 is provided on the surface of the fan-shaped mounting plate 102, and the movable hole 103 is used for slidingly connecting the nozzle trigger rod 104, one end of the nozzle trigger rod 104 passes through the inner top surface of the tank body 1, and is connected to the top surface of the rectifying plate 6, and the other end of the nozzle trigger rod 104 intermittently abuts against the nozzle switch 105; wherein One end of the fan-shaped mounting plate 102 away from the rod-shaped body 21 is fixedly connected to the inner wall of the mounting ring 101; the fan-shaped blocking plate 106 has one end hinged to the inner wall of the mounting ring 101, and the other end intermittently abuts against the circumferential outer wall of the rod-shaped body 21; wherein the fan-shaped blocking plates 106 are provided with multiple groups, and the multiple groups of fan-shaped blocking plates 106 are arranged between two groups of fan-shaped mounting plates 102; the fan-shaped blocking plates 106 and the fan-shaped mounting plates 102 form an annular plate structure, which is sleeved on the circumferential outer wall of the rod-shaped body 21; an electromagnet 107 is provided on the side of the mounting ring 101 close to the fan-shaped blocking plate 106, and the electromagnet 107 intermittently adsorbs the outer wall of the fan-shaped blocking plate 106.

[0060] During use, the discharge component 10 is used to automatically discharge after the rectifier plate 6 has reciprocated for multiple times for mixing. When the discharge component 10 is working, the electromagnet 107 is powered off and no longer adsorbs the fan-shaped plug 106. When the rectifier plate 6 is located on the inner bottom surface of the tank body 1 and moves upward, the fan-shaped plug 106 is affected by the water flow, so that the end away from the mounting ring 101 moves toward the rod-shaped body 21 until the fan-shaped plug 106 abuts against the outer wall of the rod-shaped body 21, so that the fan-shaped plug 106 and the fan-shaped mounting plate 102 form an annular plate structure, which blocks the upper part of the rectifier plate 6, so that the mixed reducing agent above the fan-shaped plug 106 can be discharged by extrusion. When the rectifier plate 6 moves, it drives the nozzle trigger rod 104 to move back and forth, so that when the nozzle trigger rod 104 touches the nozzle switch 105, the nozzle works to spray the mixed reducing agent into the flue.

[0061] In addition, a block can be set on the bottom surface of the inner ring of the mounting ring 101. When the fan-shaped baffle 106 is close to the rod-shaped body 21, the block supports the bottom end of the fan-shaped baffle 106, so that the fan-shaped baffle 106 can maintain a horizontal state, pushing the mixed reducing agent in the upper part of the tank body 1 upward and discharging it.

[0063] During use, the plurality of liquid storage tanks 111 are used to store a variety of reducing agents, such as ethanolamine, diethanolamine, triethanolamine, methylamine, etc. The various reducing agents are mixed through the tank body 1 and then sprayed into the flue through the nozzle for denitrification.
