Description

Technical Field

[0001] This utility model relates to the field of sintering flue gas treatment technology, specifically to a sintering flue gas denitrification and decarbonization device. Background Technology

[0002] Sintering flue gas is a type of industrial waste gas produced in the iron and steel industry during the iron ore sintering process. It is characterized by high temperature, high humidity, high dust concentration, and a highly complex composition. It is one of the most significant and polluting sources of waste gas in the steel industry, and its treatment is a key focus and challenge in the environmental protection field. Decarbonization (carbon dioxide emission reduction) and denitrification (nitrogen oxide emission reduction) of sintering flue gas are core measures for the steel industry to address the dual challenges of climate change and environmental pollution, and have significant environmental, social, and economic implications.

[0003] The existing device has the following shortcomings: 1. The market lacks devices that can simultaneously decarbonize and denitrify. When decarbonization and denitrification of sintering flue gas are required, multiple devices are often needed for purification, which increases the treatment cost of sintering flue gas.

[0004] 2. Sintering flue gas contains a variety of solid impurities. These solid impurities are both high-temperature and highly corrosive, which can poison catalysts, clog equipment, corrode pipelines, and trigger side reactions, thereby affecting the denitrification and decarbonization efficiency of the flue gas.

[0005] 3. The existing equipment does not have a structure designed to agitate the sintering flue gas. The flue gas tends to accumulate and does not easily come into full contact with ammonia water, thereby reducing the reduction efficiency of nitrogen oxides in the flue gas and ammonia water, and thus reducing the denitrification effect of the flue gas.

[0016] The beneficial effects of this utility model are: 1. This utility model, through the design of a flue gas pretreatment mechanism, a denitrification mechanism, and a decarbonization mechanism, can simultaneously achieve denitrification and decarbonization of sintering flue gas by working together with each other. This eliminates the need to use multiple purification devices to treat sintering flue gas separately, which helps to reduce the treatment cost of sintering flue gas.

[0017] 2. This utility model designs a flue gas pretreatment mechanism, namely a flue gas cooler, a first treatment box, and an adsorption component. The sintering flue gas drawn in from the inlet pipe 10 first enters the interior of the flue gas cooler. The flue gas cooler can reduce the flue gas temperature to about 90-100℃, thereby reducing the dust resistivity and reducing the flue gas volume flow rate, which is beneficial to improving the efficiency of subsequent electrostatic precipitators. The adsorption component removes high-temperature and highly corrosive solid impurities in the sintering flue gas, preventing impurities from poisoning the catalyst, clogging equipment, corroding pipelines, and causing side reactions, which is beneficial to improving the denitrification and decarbonization efficiency of the flue gas.

[0018] 3. This utility model designs several rotating plates and several transmission components. Since the leftmost rotating plate is close to the connecting pipe and is rotatably connected to the second processing box via a rotating shaft, the sintering flue gas entering the second processing box from the connecting pipe will cause the rotating plate to rotate when it encounters the rotating plate. Since each synchronous wheel is fixedly connected to a rotating shaft and two synchronous wheels are connected by a synchronous belt, multiple rotating plates will rotate together, which will agitate the sintering flue gas transported into the second processing box, improve its contact effect with the sprayed ammonia water droplets, and thus help to accelerate the denitrification speed of ammonia water and nitrogen oxides in the sintering flue gas, thereby improving the denitrification rate.

[0019] 4. This utility model, through the design of a honeycomb catalyst, insert plate, cover and handle, allows the sintering flue gas, after being cooled and filtered, to enter the interior of the second treatment box after passing through the honeycomb catalyst. At a specific temperature (i.e., the temperature of the cooled flue gas), in conjunction with the action of the honeycomb catalyst, it can efficiently and selectively promote the reduction reaction between ammonia water and nitrogen oxides mixed in the sintering flue gas, which is beneficial to improving the denitrification efficiency of the sintering flue gas. A handle is also fixed on one outer wall of the insert plate, which makes it convenient to quickly pull out the insert plate to replace the honeycomb catalyst after it becomes ineffective, thus improving the practicality of this device.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Reference Figures 1 to 9 The sintering flue gas denitrification and decarbonization device shown includes a base; It also includes flue gas pretreatment mechanisms, denitrification mechanisms, and decarbonization mechanisms; The flue gas pretreatment mechanism is located on the top of the base. The flue gas pretreatment mechanism includes a flue gas cooler 1, a first treatment box 2, and an adsorption assembly. The flue gas cooler 1 is fixedly located on the top of the base, the first treatment box 2 is located on the top of the base, and the adsorption assembly is located inside the first treatment box 2. The de-pinning mechanism is located beside the pretreatment mechanism. The de-pinning mechanism includes a second treatment box 3, a conveying assembly, several first atomizing nozzles 4, several rotating plates 5, and several transmission assemblies. The second treatment box 3 is located on the top of the base. The conveying assembly is located between the base and the second treatment box 3. Several first atomizing nozzles 4 are symmetrically arranged on the inner top of the second treatment box 3. Each rotating plate 5 is rotatably mounted on the second treatment box 3 via a rotating shaft 6. The several rotating plates 5 are staggered. Each transmission assembly is located between two of the rotating shafts 6. The decarbonization mechanism is located on the top of the base. The decarbonization mechanism includes a temperature sensor 7, a third processing box 8, a liquid supply assembly, a heating assembly, and several second atomizing nozzles 9. The third processing box 8 is located on the top of the base. The temperature sensor 7 is inserted into the third processing box 8. The liquid supply assembly is located between the base and the third processing box 8. The heating assembly is located inside the third processing box 8. Several second atomizing nozzles 9 are evenly spaced on the top inner side of the third processing box 8.

[0023] Reference Figures 1 to 9As shown, an inlet pipe 10 is fixedly provided at the end of the flue gas cooler 1 away from the first processing box 2, and an outlet pipe 11 is fixedly provided at the end of the third processing box 8 away from the second processing box 3. Three connecting pipes 12 are fixedly provided between the flue gas cooler 1, the first processing box 2, the second processing box 3 and the third processing box 8. The sintering flue gas drawn in from the inlet pipe 10 first enters the interior of the flue gas cooler 1. The flue gas cooler 1 can reduce the flue gas temperature to about 90-100℃, thereby reducing the dust resistivity and reducing the flue gas volume flow rate, which is beneficial to improving the efficiency of subsequent electrostatic precipitators.

[0024] Reference Figures 1 to 9 As shown, the adsorption assembly includes a micro motor 13, a fan 14, several dust collection electrode plates 15, and several discharge metal wires 16. The dust collection electrode plates 15 are vertically arranged inside the second processing box 3, and each dust collection electrode plate 15 is inserted into the second processing box 3. The several discharge metal wires 16 are fixedly arranged between the several dust collection electrode plates 15. A mounting bracket is fixedly installed inside the connecting pipe 12 located between the first processing box 2 and the second processing box 3. The micro motor 13 is inserted into the mounting bracket, and the fan 14 is fixedly installed at its output end. This device is equipped with a controller, and all electrical devices on the device are electrically connected to the controller. When denitrification of sintering flue gas is performed... When the carbon processing unit is in operation, the micro motor 13 is first started by the controller, which drives the fan 14 to rotate. This draws the sintering flue gas into the inlet pipe 10. After being cooled by the flue gas cooler 1, the flue gas is transported to the first processing box 2. Once inside the first processing box 2, the discharge wire 16 ionizes the incoming sintering flue gas through tip discharge. The flue gas carries the ionized ions through the channels between several dust collection electrode plates 15. Under the action of the high-voltage electric field, impurities in the sintering flue gas are adsorbed onto the dust collection electrode plates 15, thereby filtering the sintering flue gas and improving the subsequent denitrification and decarbonization effect.

[0025] Reference Figures 1 to 9 As shown, a cover 17 is fixedly installed on the outer wall of the connecting pipe 12 located between the first processing box 2 and the second processing box 3. A slot is opened on the outer wall of the cover 17, and an insert plate 18 is vertically inserted into the slot. A honeycomb catalyst 19 is inserted into the outer wall of the insert plate 18. After being cooled and filtered, the sintering flue gas enters the interior of the second processing box 3 through the honeycomb catalyst 19. At a specific temperature, i.e. after cooling, the honeycomb catalyst 19 can efficiently and selectively promote the reduction reaction between ammonia water and nitrogen oxides mixed in the sintering flue gas, which is beneficial to improving the denitrification efficiency of the sintering flue gas. A handle 40 is also fixedly installed on one side of the outer wall of the insert plate 18, which makes it convenient to quickly pull out the insert plate 18 to replace the honeycomb catalyst 19 after it fails, thus improving the practicality of the device.

[0026] Reference Figures 1 to 9As shown, the delivery assembly includes a first storage tank 20, a first suction pump 21, a first extraction pipe 22, a first delivery pipe 23, a first diversion pipe 24, two first receiving pipes 25, and several first branch pipes 26. The first storage tank 20 is fixedly mounted on the top of the base, the first suction pump 21 is fixedly mounted on the top of the base, each first branch pipe 26 is fixedly mounted on the outer wall of the second processing tank 3, the two first receiving pipes 25 are respectively fixedly mounted between several first branch pipes 26, each first atomizing nozzle 4 is fixedly connected to the end of a first branch pipe 26 away from the first receiving pipe 25, the first extraction pipe 22 is fixedly mounted between the first storage tank 20 and the input end of the first suction pump 21, the first diversion pipe 24 is fixedly mounted between the two first receiving pipes 25, and the first delivery pipe 23 is fixedly mounted between the first storage tank 20 and the first suction pump 21. 3 is fixedly installed between the output end of the first suction pump 21 and the first diversion pipe 24. The first storage tank 20 stores ammonia water. After the sintering flue gas is cooled and filtered, it enters the second treatment box 3 through catalysis. The first suction pump 21 is started by the controller. The ammonia water in the first storage tank 20 is transported to the inside of several first atomizing nozzles 4 through the cooperation of the first suction pump 21, the first extraction pipe 22, the first delivery pipe 23, the first diversion pipe 24, the two first receiving pipes 25 and several first branch pipes 26. Then, the ammonia water is sprayed into the inside of the second treatment box 3 by the several first atomizing nozzles 4, thereby spraying ammonia water droplets onto the sintering flue gas. The ammonia water reacts with the nitrogen oxides mixed in the sintering flue gas to achieve the denitrification effect of the sintering flue gas.

[0027] Reference Figures 1 to 9 As shown, the transmission assembly includes a synchronous belt 27 and two synchronous pulleys 28. Each synchronous pulley 28 is fixedly mounted on a rotating shaft 6, and the synchronous belt 27 is sleeved between the two synchronous pulleys 28. Since the leftmost rotating plate 5 is close to the connecting pipe 12, and the rotating plate 5 is rotatably connected to the second processing box 3 through the rotating shaft 6, the sintering flue gas entering the second processing box 3 from the connecting pipe 12 will cause the rotating plate 5 to rotate when it encounters the rotating plate 5. Since each synchronous pulley 28 is fixedly connected to a rotating shaft 6, and the two synchronous pulleys 28 are sleeved through the synchronous belt 27, multiple rotating plates 5 will rotate together, agitating the sintering flue gas transported into the second processing box 3, improving its contact effect with the sprayed ammonia water droplets, and thus helping to accelerate the denitrification speed of ammonia water and nitrogen oxides in the sintering flue gas, which is beneficial to improving the denitrification rate.

[0028] Reference Figures 1 to 9As shown, the liquid supply assembly includes a second storage tank 29, a second suction pump 30, a second extraction pipe 31, a second delivery pipe 32, a second diversion pipe 33, three second receiving pipes 34, and several second branch pipes 35. The second storage tank 29 is fixedly mounted on the top of the base, the second suction pump 30 is fixedly mounted on the top of the base, each second branch pipe 35 is fixedly mounted on the outer wall of the third processing tank 8, the three second receiving pipes 34 are respectively fixedly mounted between several second branch pipes 35, each second atomizing nozzle 9 is fixedly connected to the end of a second branch pipe 35 away from the second receiving pipe 34, the second extraction pipe 31 is fixedly mounted between the input ends of the second storage tank 29 and the second suction pump 30, and the second diversion pipe 33 is fixedly mounted between the three second receiving pipes 34. The second delivery pipe 32 is fixed between the output end of the second suction pump 30 and the second diversion pipe 33. The denitrified sintering flue gas continues to be transported to the third processing box 8 under the action of the fan 14. When the denitrified sintering flue gas enters the interior of the third processing box 8, the second suction pump 30 is started by the controller. Thus, through the cooperation of the second suction pump 30, the second extraction pipe 31, the second delivery pipe 32, the second diversion pipe 33, the three second receiving pipes 34 and several second branch pipes 35, the amine liquid stored in the second storage tank 29 is sprayed into the interior of the third processing box 8 from top to bottom through several evenly installed second atomizing nozzles 9, so that the amine liquid and the carbon dioxide in the sintering flue gas undergo a reversible chemical reaction and absorb it.

[0029] Reference Figures 1 to 9 As shown, the heating assembly includes two mounting plates 36 and several electric heating plates 37. The two mounting plates 36 are fixedly installed on the inner wall of the third processing box 8, and the several electric heating plates 37 are symmetrically arranged on the two mounting plates 36. Each electric heating plate 37 is fixedly connected to the mounting plate 36. After absorption, the controller activates several electric heating plates 37 to uniformly heat the flue gas inside the third processing box 8, desorbing high-purity carbon dioxide, which is then discharged through the exhaust pipe 11, achieving purified emission of sintering flue gas and reducing pollution. The temperature sensor 7 can monitor the heating temperature in real time to ensure that the heating temperature meets the desorption standard, which is beneficial to improving the decarbonization efficiency of the sintering flue gas.

[0030] Reference Figures 1 to 9 As shown, the bottom of the second treatment box 3 and the third treatment box 8 are both fixedly equipped with discharge pipes 38. Each discharge pipe 38 is fixedly equipped with a solenoid valve 39 on its outer wall. The two discharge pipes 38 can discharge the reactants generated during the denitrification and decarbonization process of the sintering flue gas in a timely manner to prevent them from affecting the denitrification and decarbonization effect of the sintering flue gas.
