Description

Technical Field

[0001] The present invention belongs to the technical field of waste incineration flue gas treatment, and in particular is a flue gas treatment device and a treatment method for waste incineration fly ash resource utilization. Background Art

[0002] Waste incineration technology has become an important measure to solve the increasingly serious waste pollution problem and alleviate the energy crisis. However, the incineration process produces a large amount of acidic gases (such as SO2 and HCl, etc.), and direct emission will cause irreversible damage to the environment. The most commonly used method is the semi-dry flue gas desulfurization plus bag filter purification method to ensure that the treated flue gas emissions meet environmental protection standards.

[0003] The patent with application number CN202310829192.6 discloses a flue gas treatment device for power generation from incineration of domestic waste, including a lime tank, a lime slurry preparation tank, and a lime slurry storage tank. The bottom of the lime tank is fixedly connected to a hopper, and two connecting pipes are arranged at the bottom of the hopper. The connecting pipes are all inclined outwards, and solenoid valves are installed on the connecting pipes. The solenoid valves are used for quantitative delivery of lime powder. The connecting pipes are connected to the lime slurry preparation tank at one end away from the lime tank. The tops of the lime slurry preparation tanks are connected together through a water inlet pipe, and a water pump is installed on the water inlet pipe. The above scheme effectively solves the problem that the existing design blows off the lime powder on the wall of the lime bin through a purge device, so that all the lime powder in the lime bin is blown away, and the lime has strong hygroscopicity, and the long-term use slows down the fluidity of the lime powder, which is easy to agglomerate and affects the preparation efficiency of the lime slurry. However, the above-mentioned prior art only records how to avoid the solidification of the lime slurry, and cannot efficiently treat the flue gas.

[0004] In addition, when treating the flue gas generated after garbage incineration, a large amount of floating matter produced by incineration will appear in the flue gas. If the floating matter is not treated, it will accumulate in large quantities inside the flue gas treatment device. In serious cases, it will interfere with the neutralization efficiency between the flue gas and the acid scavenger, which is not conducive to the treatment of the flue gas.

[0005] In order to solve the above technical problems, the present invention proposes a flue gas treatment device and a treatment method for recycling fly ash from waste incineration. Summary of the invention

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] like Figure 1-Figure 7As shown, this embodiment discloses a flue gas treatment device for recycling fly ash from waste incineration, including a bearing assembly 1 for limiting a flue gas transmission path, a smoke inlet assembly 2 connected to the bearing assembly 1, the bearing assembly 1 including a bearing shell 101, a smoke chamber 103 opened in the bearing shell 101, and flue gas can be harmlessly treated in the smoke chamber 103, the smoke inlet assembly 2 penetrates the bearing shell 101 and is connected to the smoke chamber 103, wherein the flue gas after the waste incineration enters the bearing assembly 1 through the smoke inlet assembly 2, and a connecting frame 8 is connected to the smoke inlet assembly 2, wherein the connecting frame 8 It is composed of a telescopic rod, and the length can be self-adjusted. A dispersion component 7 is connected to the end of the connecting frame 8 away from the smoke inlet component 2, wherein the dispersion component 7 is directly opposite to the smoke outlet of the smoke inlet component 2. When the smoke inlet component 2 transports the smoke generated by the incineration of garbage, the smoke collides with the dispersion component 7 to be dispersed, and in the process of collision, the floating objects in the smoke can be blocked, so that the floating objects adhere to the dispersion component 7, reducing the amount of the floating objects entering the air, and at the same time, the dispersion component 7 is used to weaken the smoke transmission speed to ensure that the smoke can be fully reacted in the smoke chamber 103.

[0037] In addition, the flue gas after garbage incineration contains acidic substances, and direct discharge will cause pollution to the atmosphere. In order to neutralize the acidic substances in the flue gas, an acid removal component 4 is also connected to the supporting shell 101. One end of the acid removal component 4 is located in the smoke chamber 103, and the end of the supporting shell 101 away from the smoke inlet component 2 is connected to the smoke outlet component 3. The acid removal component 4 can be used to introduce external deacidifying agents into the smoke chamber 103, mix with the flue gas, and then deacidify. The acid removal component 4 is preferably a transmission pipe and an atomizing nozzle, and the deacidifying agent formed by the atomizing nozzle can fully contact with the flue gas, and under the action of the flue gas, water mist accumulation will not occur.

[0038] Furthermore, in order to ensure that the smoke is fully dispersed, the dispersion component 7 includes a connection shell 701 for restraint, and a cavity 7012 is opened through the connection shell 701. A movable plate 703 is slidably provided at one end of the cavity 7012 close to the smoke inlet component 2, wherein the end of the movable plate 703 away from the fixed plate 704 is a concave surface, so that floating objects in the smoke can be adsorbed. An elastic rod 705 is connected to the end of the movable plate 703 away from the smoke inlet component 2. When there is no floating object attached to the movable plate 703, the elastic rod 705 is in a normal elongated state under the gravity of the movable plate 703. When there is floating object attached to the movable plate 703, the gravity on the movable plate 703 As the force increases, the length of the elastic rod 705 will be extended, so that the surface of the movable plate 703 can be cleaned in time, ensuring that the movable plate 703 can effectively adsorb floating objects and reduce the probability of entering the air. The end of the elastic rod 705 away from the movable plate 703 is connected with a fixed plate 704, and the fixed plate 704 does not completely cover the end of the cavity 7012, so that part of the smoke can pass through the cavity 7012 and enter the subsequent smoke cavity 103. At the same time, in the process of using the movable plate 703 to adsorb floating objects in the smoke, on the one hand, the probability of floating objects entering the air is reduced, and on the other hand, the rate at which the deacidifying agent and the smoke are neutralized can be reduced.

[0039] Furthermore, in order to ensure that the smoke after garbage incineration can be effectively treated, the smoke inlet component 2 includes a smoke inlet pipe 201, one end of the smoke inlet pipe 201 passes through the supporting shell 101, and the other end of the smoke inlet pipe 201 is located in the smoke chamber 103, so that the smoke generated after garbage incineration can enter the smoke chamber 103 through the smoke inlet pipe 201, so that the smoke is purified and treated in the smoke chamber 103, reducing the impact of the smoke on the environment.

[0040] In order to be able to adjust the transmission path of the smoke, thereby ensuring that the smoke is fully processed in the smoke chamber 103, further, a rotating part 202 is connected to the smoke inlet pipe 201 located in the smoke chamber 103, and the smoke inlet pipe 201 is composed of a fixed part and a rotating part. The end of the rotating part 202 close to the dispersion component 7 is the rotating part, and the end away from the dispersion component 7 is the fixed part, wherein the fixed part passes through the supporting shell 101, and the rotating parts are all located in the smoke chamber 103. According to the smoke treatment efficiency, the rotating part 202 is used to rotate one end of the rotating part of the smoke inlet pipe 201, so as to adjust the smoke outlet angle of the smoke inlet pipe 201 to adapt to the treatment efficiency under different smoke levels.

[0041] When the amount of smoke passing through the smoke inlet pipe 201 is small, the rotating part 202 is used to control the outlet end of the smoke inlet pipe 201 to face one end of the smoke outlet component 3, so that the smoke passing through the smoke chamber 103 quickly approaches the smoke outlet component 3, thereby improving the smoke treatment efficiency. When the smoke content passing through the smoke inlet pipe 201 is high, the rotating part 202 is controlled to rotate so that the smoke outlet end of the smoke inlet pipe 201 turns to the side close to the cleaning component 6, thereby enhancing the travel path of the smoke in the smoke chamber 103, thereby increasing the mixing time between the acid removal component 4 and the smoke, ensuring that the smoke can be fully treated.

[0042] It should be noted that no matter what angle the rotating part 202 is at, the smoke passing through the smoke inlet pipe 201 first acts on the dispersion component 7 and then enters the smoke chamber 103 for processing.

[0043] Furthermore, in order to reduce the transmission speed of smoke in the smoke chamber 103 and ensure that the acid remover on the acid removal component 4 is fully contacted and mixed with the smoke, a plurality of arc plates 102 are connected to the cavity wall of the smoke chamber 103, and the plurality of arc plates 102 are all located on the side of the connecting shell 701 close to the smoke outlet component 3, so that when the smoke is transmitted in the smoke chamber 103, it can be blocked by the arc plates 102, which on the one hand changes the flow path of the smoke in the smoke chamber 103, and on the other hand increases the residence time of the smoke in the smoke chamber 103, so that the acid remover released by the acid removal component 4 is fully contacted with the smoke. At the same time, due to the plurality of arc plates 102 interferes with the smoke, weakening the flow rate of the smoke in the smoke chamber 103. In order to avoid the strong interference of the arc plate 102 on the smoke path, the smoke concentration on both sides of the arc plate 102 is greatly different, which is not conducive to the full treatment of the smoke. Smoke grooves 1021 are opened on multiple arc plates 102. When the arc plate 102 interferes with the smoke, part of the smoke passes through the arc plate 102 through the smoke grooves 1021 and directly contacts and mixes with the acid removal agent of the acid removal component 4, and then is discharged from the smoke chamber 103 through the smoke outlet component 3, thereby reducing the smoke concentration difference on both sides of the arc plate 102.

[0044] Since the smoke after the incineration of garbage contains floating objects, and the heat of the smoke gradually decreases during the transmission of the smoke, the floating dust in the smoke will be caused to adhere to the smoke treatment device, and since the dispersion component 7 is directly opposite to the smoke outlet of the smoke inlet pipe 201, most of the floating objects will accumulate on the surface of the dispersion component 7, and as the accumulation on the surface of the dispersion component 7 increases, the dispersion efficiency of the smoke on the surface of the dispersion component 7 will be weakened. Furthermore, a cleaning component 6 is connected to the end of the supporting shell 101 away from the smoke outlet component 3, and the cleaning component 6 includes a raised plate 602, and the raised plate 602 corresponds to the movable plate 703 in space. When more floating objects are accumulated on the movable plate 703, the raised plate 602 is used to move with the movable plate 7 03 contacts and rotates, so that the raised plate 602 cleans the concave surface of the movable plate 703, ensuring that the movable plate 703 always has a dispersing effect on the smoke. A plurality of fan-shaped plates 601 are connected to the raised plate 602, and the plurality of fan-shaped plates 601 are rotatably connected to the supporting shell 101. After the raised plate 602 cleans the movable plate 703, the accumulation situation on the raised plate 602 is identified according to the detection result of the movable plate 703. When there are a lot of accumulations on the raised plate 602, the raised plate 602 is controlled to move to the end away from the smoke chamber 103, and the fan-shaped plate 601 is controlled to rotate, so that the smoke chamber 103 is opened. At the same time, as the fan-shaped plate 601 rotates, the sediment at the bottom of the smoke chamber 103 is discharged.

[0045] After the raised plate 602 cleans the movable plate 703, the dispersion component 7 is controlled to move to one end close to the smoke outlet component 3. If the length of the elastic rod 705 is at a normal extension length at this time, it means that there is less deposit on the raised plate 602 at this time, which can meet the cleaning of the movable plate 703. When the length of the elastic rod 705 is longer, it means that there is more deposit on the raised plate 602 at this time, which affects the cleaning efficiency of the movable plate 703, and then the fan-shaped plate 601 is controlled to rotate to clean the floating objects in the smoke chamber 103.

[0046] Furthermore, the dispersion component 7 also includes a plurality of air holes 7011, which penetrate the connecting shell 701 and communicate with the cavity 7012, wherein most of the smoke impacting the surface of the movable plate 703 enters the smoke chamber 103 from the edge of the movable plate 703, and a small part directly enters the smoke chamber 103 through the air holes 7011, thereby causing the smoke transmission path in the smoke chamber 103 to be disordered, which can cause the acid removal component 4 to re-purify the smoke inside the smoke chamber 103, in order to In order to avoid smoke deposition, a rotating shaft 702 is connected to the connecting shell 701, and the rotating shaft 702 is connected to the connecting frame 8. A fan blade 706 is rotatably provided on the elastic rod 705, and the fan blade 706 is located on the cavity 7012. The rotation of the fan blade 706 disturbs the air in the cavity 7012, so that the smoke can enter the cavity 7012 through the air hole 7011, thereby avoiding the situation where the smoke moves slowly in the air hole 7011 and causes floating objects to accumulate in the air hole 7011.

[0047] Furthermore, a support frame 5 is connected to one end of the carrying shell 101 away from the smoke outlet assembly 3 to support the carrying assembly 1 .

[0048] During operation, the smoke generated by the garbage incineration is introduced into the smoke chamber 103 through the smoke inlet pipe 201. Initially, the dispersion component 7 is controlled by the rotating part 202 so that the dispersion component 7 is located at one end close to the smoke outlet component 3, and the movable plate 703 is opposite to the smoke outlet of the smoke inlet pipe 201, thereby enabling the smoke passing through the smoke inlet pipe 201 to directly act on the dispersion component 7, causing the smoke to be dispersed on the dispersion component 7 and be able to be transmitted in the smoke chamber 103, and controlling the acid removal component 4 to release the acid removal agent to react with the smoke in the smoke chamber 103 to eliminate the acidic substances in the smoke, and when the smoke is transported in the smoke chamber 103, it can be interfered by the arc plate 102 to ensure that the residence time of the smoke in the smoke chamber 103 can meet the acid removal time of the acid removal component 4.

[0049] When smoke passes through the smoke inlet pipe 201 and impacts the movable plate 703, the smoke content in the smoke inlet pipe 201 is judged based on the impact pressure of the movable plate 703, that is, the impact force of the smoke on the movable plate 703 can drive the movable plate 703 to move, and at the same time cause the compression of the elastic rod 705. The smoke content is judged based on the compression depth of the elastic rod 705. When the compression amount of the elastic rod 705 is large, it means that the smoke content in the smoke inlet pipe 201 is large. Otherwise, it means that the smoke content in the smoke inlet pipe 201 is small.

[0050] It should be noted that, as the smoke emission time increases, the weight of the floating objects attached to the surface of the movable plate 703 increases, thereby causing the weight of the movable plate 703 to increase. When the smoke concentration does not change, the moving distance of the movable plate 703 will be shortened, causing the compression depth of the elastic rod 705 to shorten. In order to ensure the accuracy of the detection data of the elastic rod 705, when the moving distance of the movable plate 703 is shortened, the length of the control connecting frame 8 is shortened, so that the movable plate 703 is close to the smoke outlet of the smoke inlet pipe 201, and the impact force of the smoke and the increased gravity on the movable plate 703 are offset each other, ensuring that the compression change of the elastic rod 705 can accurately identify the smoke concentration.

[0051] If the smoke content is low, the rotating part 202 does not rotate, and the position of the dispersion component 7 remains unchanged. When the smoke enters the smoke chamber 103 from the smoke inlet pipe 201, it first impacts the movable plate 703, and the movable plate 703 is used to adsorb the floating matter carried in the smoke, thereby achieving simple filtration of the smoke, reducing the probability of floating matter entering other areas of the smoke chamber 103, and improving the mixing efficiency between the acid scavenger and the smoke.

[0052] If the smoke content is high, the rotating part 202 is controlled to rotate, driving the dispersion component 7 to rotate to the side close to the cleaning component 6, thereby increasing the distance of the smoke to the smoke outlet component 3, increasing the residence time of the smoke in the smoke chamber 103, and improving the purification efficiency of the smoke.

[0053] In addition, during the process of smoke transmission in the smoke chamber 103, the air holes 7011 and the smoke grooves 1021 are used to transmit the smoke in the smoke chamber 103, thereby preventing the smoke from being excessively accumulated in the smoke chamber 103 and affecting the emission and purification efficiency of the smoke. Specifically, when the smoke acts on the movable plate 703, most of the smoke enters the smoke chamber 103 along the edge of the movable plate 703, and a small amount of smoke directly enters the smoke chamber 103 through the air holes 7011, thereby causing a speed difference in the smoke transmission process, which is convenient for the timely treatment of the smoke by the acid removal component 4. At the same time, most of the smoke passing through the curved plate 102 is The interference of the smoke passing through the arc plate 102 causes the path change and suppresses the transmission rate of the smoke in the smoke chamber 103. At the same time, part of the smoke passes through the arc plate 102 directly through the smoke groove 1021 to avoid excessive accumulation of smoke on the side of the arc plate 102 close to the smoke inlet component 2, which affects the purification efficiency of the smoke. At the same time, a multi-level dispersion mode of the movable plate 703, the air hole 7011, the arc plate 102 and the smoke groove 1021 is formed to ensure that the smoke is fully processed by the acid removal component 4 in the smoke chamber 103 while still maintaining the transmission rate of the smoke in the smoke chamber 103, avoiding the accumulation of smoke in the smoke chamber 103.

[0054] After the movable plate 703 is used to absorb the floating objects in the smoke, the weight of the movable plate 703 will increase, thereby affecting the elastic depth of the elastic rod 705. When the compression amount of the elastic rod 705 is close to the maximum compression or extension length, the dispersion component 7 is controlled to be close to the cleaning component 6, and the position of the raised plate 602 corresponds to the position of the movable plate 703, thereby controlling the length of the connecting frame 8 to extend, and at the same time causing the connecting shell 701 to flip 180°, so that the raised plate 602 can directly contact the movable plate 703, so that the raised plate 602 can be used to clean the floating objects absorbed on the surface of the movable plate 703, and after cleaning, the movable plate 703 is controlled to face the smoke outlet of the smoke inlet pipe 201.

[0055] At the same time, the accumulation situation on the raised plate 602 is identified according to the detection result of the movable plate 703. When there is a lot of accumulation on the raised plate 602, the raised plate 602 is controlled to move to the end away from the smoke chamber 103, and the fan-shaped plate 601 is controlled to rotate to open the smoke chamber 103. At the same time, as the fan-shaped plate 601 rotates, the sediment at the bottom of the smoke chamber 103 is discharged.

[0056] After the raised plate 602 cleans the movable plate 703, the dispersion component 7 is controlled to move to one end close to the smoke outlet component 3. If the length of the elastic rod 705 is at a normal extension length at this time, it means that there is less deposit on the raised plate 602 at this time, which can meet the cleaning of the movable plate 703. When the length of the elastic rod 705 is longer, it means that there is more deposit on the raised plate 602 at this time, which affects the cleaning efficiency of the movable plate 703, and then the fan-shaped plate 601 is controlled to rotate to clean the floating objects in the smoke chamber 103.
