Description

Technical Field

[0001] This invention relates to the field of flue gas purification technology, and more specifically, to an ultra-low emission device for activated coke with a matching dust removal module and its usage method. Background Technology

[0002] Activated coke flue gas purification technology can achieve integrated removal of multiple pollutants such as sulfides, nitrogen oxides, particulate matter, dioxins, and heavy metals. This technology produces no secondary pollutants, and byproducts can be recycled, enabling coordinated economic and environmental development. Currently, activated coke flue gas purification technology is divided into counter-current bed technology and cross-flow bed technology based on the different contact methods between flue gas and activated coke. Cross-flow bed technology is recognized by the market due to its large contact area and low resistance between flue gas and activated coke. Among cross-flow bed technologies, the two-stage cross-flow moving bed technology is widely used due to its high activated coke utilization rate and low operating cost.

[0003] With the implementation of ultra-low emission standards for flue gas, the concentration of particulate matter at the outlet of the activated coke two-stage cross-flow moving bed flue gas treatment process is difficult to control. While the particulate matter concentration at the flue gas outlet is close to the national ultra-low emission control targets, fluctuations in the inlet flue gas can lead to exceedances of the outlet particulate matter standard. Currently, the two-stage cross-flow moving bed flue gas treatment system has certain limitations in terms of guarantee measures in the face of technology promotion and increasingly stringent national ultra-low emission standards.

[0004] Therefore, there is an urgent need for a method that can effectively control the concentration of particulate matter at the flue gas outlet, improve the adaptability of the device to flue gas, and enhance the adaptability of the two-stage cross-flow moving bed device for subsequent ultra-low emission upgrades.

The upper part of the flue gas intermediate zone extends to one side of the upper partition, and a flue gas outlet zone is provided on the side of the upper partition away from the flue gas intermediate zone. A denitrification agent is provided in the flue gas intermediate zone.

[0013] The flue gas to be treated is sequentially processed through the flue gas inlet zone, the first desulfurization module, the second desulfurization module, the flue gas intermediate zone, the first denitrification module, the second denitrification module, the dust removal module, and the flue gas outlet zone.

[0014] In addition, a preferred embodiment is that a first material distribution plate is provided between the first desulfurization module and the second desulfurization module, a second material distribution plate is provided between the first denitrification module and the second denitrification module, and a third material distribution plate is provided between the second denitrification module and the dust removal module.

[0016] Furthermore, in a preferred embodiment, the first denitrification module, the first desulfurization module, the first feed chute, and the first discharge control device constitute a first adsorption zone; the second denitrification module, the second desulfurization module, the second feed chute, and the second discharge control device constitute a second adsorption zone; and the dust removal module, the dust removal feed chute, and the dust removal discharge control device constitute a dust removal zone.

[0020] The two individual units share a flue gas inlet zone and a flue gas outlet zone located in the middle.

[0021] On the other hand, the present invention also provides a method of using an activated coke ultra-low emission device with a matching dust removal module as described above, the method comprising:

[0022] The flue gas to be treated, which is introduced from the flue gas inlet area, passes through the first desulfurization module and the second desulfurization module in sequence before entering the flue gas intermediate zone.

[0023] The flue gas after desulfurization treatment is in full contact with the denitrification agent in the middle zone of the flue gas;

The dust removal module is equipped with a dedicated control device (dust discharge control device), which controls the circulation rate of activated coke in the dust removal module (i.e., the movement speed of activated coke in the dust removal module), reduces the contact between flue gas and dust attached to activated coke, thereby preventing dust attached to activated coke from entering the dust removal module, controlling the particulate matter concentration in the outlet flue gas, and further achieving ultra-low emissions of flue gas.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] To make the objectives, technical solutions, and advantages of the present invention clearer, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Figure 1 A first structural diagram of an activated coke ultra-low emission device with a matching dust removal module according to the present invention is shown.

[0037] Depend on Figure 1 As can be seen, the activated coke ultra-low emission device with matching dust removal module d1 provided by the present invention includes an upper section (not shown in the figure) at the top and a lower section (not shown in the figure) at the bottom. The lower section is provided with a first desulfurization module b3 and a second desulfurization module c3 for desulfurizing the flue gas to be treated. The upper section is provided with a first denitrification module b1 and a second denitrification module c1 for denitrifying the flue gas to be treated. In addition, the upper section is also provided with a dust removal module d1 for dust removal of the flue gas to be treated.

[0038] In the actual processing, the flue gas to be treated enters the lower partition from one side, and is desulfurized by the first desulfurization module b3 and the second desulfurization module c3 in sequence. After being desulfurized, it flows out from the other side of the lower partition, and then enters the upper partition from one side of the upper partition. After being denitrified by the first denitrification module b1 and the second denitrification module c1 in sequence, it enters the dust removal module d1 for dust removal. After being dusted by the dust removal module d1, it flows out from the other side of the lower partition.

[0039] Specifically, activated coke is filled in the first desulfurization module b3, the second desulfurization module c3, the first denitrification module b1, the second denitrification module c1, and the dust removal module d1. Furthermore, a first feed chute b2 is connected between the first denitrification module b1 and the first desulfurization module b3, a second feed chute c2 is connected between the second denitrification module c1 and the second desulfurization module c3, and a dust removal feed chute d3 is connected between the dust removal module d1 and the first desulfurization module b3. In addition, a first discharge control device b4, a second discharge control device c4, and a dust removal discharge control device d2 are respectively installed at the bottom of the first desulfurization module b3, the bottom of the first denitrification module b1, and on the third feed chute.

[0040] With the above configuration, the activated carbon in the first desulfurization module b3, the second desulfurization module c3, the first denitrification module b1, the second denitrification module c1, and the dust removal module d1 can be made to flow, thereby timely discharging the activated carbon that has been fully adsorbed. In addition, by setting the first discharge control device b4, the second discharge control device c4, and the dust removal discharge control device d2, the flow rate of the activated carbon can be effectively controlled, thereby improving the effective adsorption effect of the activated carbon in the system.

[0041] Additionally, it should be noted that activated coke has the strongest sulfur adsorption effect. Therefore, by setting up a desulfurization module in the lower section and a denitrification module and a dust removal module d1 in the upper section, the activated coke in the upper section can first undergo denitrification and dust removal treatment in the actual process, and then flow into the first desulfurization module b3 or the second desulfurization module c3. Based on the characteristics of activated coke, it can still desulfurize the flue gas.

[0042] In addition, to facilitate the replenishment of activated coke to the first desulfurization module b3, the second desulfurization module c3, the first denitrification module b1, the second denitrification module c1, and the dust removal module d1, a top material pile device a can be set above the upper partition. Activated coke is then supplied to the first denitrification module b1, the second denitrification module c1, and the dust removal module d1 through the top material pile device a. Activated coke flows sequentially from the first denitrification module b1, the second denitrification module c1, and the dust removal module d1 into the first desulfurization module b3 or the second desulfurization module c3 via the first material guide pipe b2, the second material guide pipe c2, and the dust removal material guide pipe d3.

[0043] In one specific embodiment of the present invention, a flue gas inlet zone e is provided on one side of the lower partition, and a flue gas intermediate zone f is provided on the other side of the lower partition away from the flue gas inlet zone e. The upper part of the flue gas intermediate zone f extends to one side of the upper partition, and a flue gas outlet zone g is provided on the side of the upper partition away from the flue gas intermediate zone f. A denitrification agent is provided in the flue gas intermediate zone f, and a sulfide detection device is provided in the flue gas intermediate zone f to monitor the sulfide content of the flue gas in the intermediate zone in real time.

[0044] In the actual processing, the flue gas to be treated first enters through the flue gas inlet zone e, and then passes through the first desulfurization module b3 and the second desulfurization module c3 sequentially from one side of the lower zone. After desulfurization, it flows out from the other side of the lower zone and enters the flue gas intermediate zone f. After being fully mixed with the denitrification agent in the flue gas intermediate zone f, it enters the upper zone from the same side of the upper zone, and passes through the first denitrification module b1 and the second denitrification module c1 for denitrification. Then it enters the dust removal module d1 for dust removal, and finally flows out from the other side of the upper zone and enters the flue gas outlet zone g, and finally flows into the outside.

[0045] In addition, to prevent the material (activated coke) within each module from flowing laterally, a first distribution plate 1 can be installed between the first desulfurization module b3 and the second desulfurization module c3, a second distribution plate 2 can be installed between the first denitrification module b1 and the second denitrification module c1, and a third distribution plate 3 can be installed between the second denitrification module and the dust removal module d1. The distribution plates are used to isolate the material. Of course, to prevent the material from entering the flue gas inlet zone e, the flue gas intermediate zone f, and the flue gas outlet zone g, a first partition plate 11 can be installed between the flue gas inlet zone e and the first desulfurization module b3, a second partition plate 12 can be installed between the flue gas intermediate zone f and the support of the second desulfurization module c3, a third partition plate 13 can be installed between the flue gas intermediate zone f and the first denitrification module b1, and a fourth partition plate 14 can be installed between the flue gas outlet zone g and the dust removal module d1.

[0046] It should be noted that, since the activated coke carried in the first denitrification module b1, the first desulfurization module b3, and the first feed chute b2 are in the same flow system and are controlled by the first discharge control device b4, the system consisting of the first denitrification module b1, the first desulfurization module b3, the first feed chute b2, and the first discharge control device b4 can be called the first adsorption zone b; similarly, since the activated coke in the second denitrification module c1, the second desulfurization module c3, and the second feed chute c2 are in the same flow system and are controlled by the second discharge control device c4, the system consisting of the second denitrification module c1, the second desulfurization module c3, the second feed chute c2, and the second discharge control device c4 can be called the second adsorption zone c; similarly, the system consisting of the dust removal module d1, the dust removal feed chute d3, and the dust removal discharge control device d2 can be called the dust removal zone.

[0047] In the actual design process, since the first adsorption zone b is used for the first desulfurization treatment and the first denitrification treatment, in order to achieve the corresponding adsorption efficiency, the material flow rate of the first adsorption zone b needs to be set to be greater than the material flow rate of the second adsorption zone c, and the thickness of the first adsorption zone b (referring to the thickness of the first desulfurization module b3 and the first denitrification module b1) needs to be set to be greater than the thickness of the second adsorption zone c (referring to the thickness of the second desulfurization module c3 and the second denitrification module c1).

[0048] Specifically, in order to achieve the corresponding adsorption effect and effectively save resources, the thickness of the first adsorption zone b is usually set between 1300mm and 1400mm, and the thickness of the second adsorption zone c is usually set between 300mm and 400mm.

[0049] Furthermore, in a preferred embodiment of the present invention, Figure 2 The second structure of the activated coke ultra-low emission device according to the present invention is shown, consisting of a matching dust removal module d1. Figure 2 It can be seen that a first adsorption zone b, a second adsorption zone c, and a dust removal zone constitute a single unit. The activated coke ultra-low emission device with matching dust removal module d1 can include two single units arranged symmetrically. The two single units share a flue gas inlet zone e and a flue gas outlet zone g located in the middle. Through this design, the installation of a flue gas inlet zone e and a flue gas outlet zone g can be reduced, thereby further reducing the installation cost.

[0050] Furthermore, to further illustrate the working principle of the ultra-low emission device for activated coke with matching dust removal module d1 according to the present invention, the present invention also provides a method for using the ultra-low emission device for activated coke with matching dust removal module d1, the method comprising:

[0051] The flue gas to be treated, which is introduced from the flue gas inlet zone e, is desulfurized by the first desulfurization module b3 and the second desulfurization module c3 in sequence before entering the flue gas intermediate zone f.

[0052] After desulfurization, the flue gas comes into full contact with the denitrification agent in the intermediate zone f.

[0053] After being fully in contact with the denitrification agent, the flue gas is sequentially denitrified through the first denitrification module b1 and the second denitrification module c1 before entering the dust removal module d1.

[0054] After denitrification, the flue gas is removed by the dust removal module d1 and then discharged through the flue gas outlet zone g.

[0055] Specifically, the flue gas process flow is as follows: The flue gas enters the flue gas inlet zone e, and diffuses evenly through the first partition plate 11 to the first desulfurization module b3. In the first desulfurization module b3, most of the sulfides in the flue gas are adsorbed by the activated coke in the desulfurization module. The flue gas then enters the second desulfurization module c3 through the first distribution plate 1. The sulfur in the flue gas that was not adsorbed in the first desulfurization module b3 completes the adsorption reaction in the second desulfurization module c3, and then passes through the first partition plate 12 into the flue gas intermediate zone f. In the flue gas intermediate zone f, it is fully mixed with the denitrification agent, and then passes through the third partition plate 13 into the first denitrification module b1. After most of the nitrogen oxides are reacted in the first denitrification module b1, it enters the second denitrification module c1 through the second distribution plate 2. After the nitrogen oxides are completely removed in the second denitrification module c1, it enters the dust removal module d1 through the third distribution plate 3. After dust removal by the dust removal module d1, it passes through the fourth partition plate 14 into the flue gas outlet zone g and is discharged outside the system.

[0056] Correspondingly, the activated coke process flow is as follows: The activated coke in the top feed cone a is divided into three parts, which enter the first denitrification module b1, the second denitrification module c1, and the dust removal module d1 respectively. After completing the denitrification reaction, the activated coke in the first denitrification module b1 is guided to the first desulfurization module b3 through the first feed chute b2. After sulfide adsorption saturation, it is discharged by the first discharge control device b4. Similarly, after completing the denitrification reaction, the activated coke in the second denitrification module c1 is guided to the second desulfurization module c3 through the second feed chute c2. After adsorption saturation, it is discharged by the second discharge control device c4. Finally, after completing dust adsorption, the activated coke in the dust removal module d1 is discharged into the first desulfurization module b3 through the dust removal discharge control device d2 and the dust removal feed chute d3.

[0057] It should be noted that the matching dust removal module d1 is located between the second denitrification module c1 and the gas outlet zone g. Furthermore, the dust removal module d1 is the last process in which the flue gas comes into contact with the activated coke. Therefore, the width of the dust removal module d1 needs to be set between 200 and 500 mm.

[0058] Furthermore, in the first adsorption zone b, the first denitrification module b1 is connected to the first desulfurization module b3 via the first feed chute b2. In the desulfurization module, the flue gas first contacts the first desulfurization module b3; in the denitrification module, the flue gas first contacts the first denitrification module b1. In the second adsorption zone c, the second denitrification module c1 is connected to the second desulfurization module c3 via the second feed chute c2. In the desulfurization module, the flue gas enters the second desulfurization module c3 after passing through the first desulfurization module; in the denitrification module, the flue gas contacts the second denitrification module c1 after passing through the first denitrification module. Additionally, the dust removal discharge control device d2 controls the discharge speed based on the particulate matter concentration monitored by the CEMS at the flue gas outlet.

[0059] The ultra-low emission device for activated coke with a matching dust removal module according to the present invention and its method of use have been described above by way of example with reference to the accompanying drawings. However, those skilled in the art should understand that various modifications can be made to the ultra-low emission device for activated coke with a matching dust removal module and its method of use proposed in the present invention without departing from the scope of the invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
