Description

Technical Field

[0001] The present invention relates to the technical field of waste flue gas utilization, and in particular to a device for recycling waste flue gas from a hot blast furnace. Background Art

[0002] Hot blast furnaces, thermal equipment that provides blast air for blast furnaces, are diverse in type and have a long history of technological development. Early hot blast furnaces used simple structures such as tubular heat exchangers. With technological advancements, the utilization of waste gas from hot blast furnaces has gradually developed.

[0003] In the resource recycling industry, the waste flue gas generated by the hot blast furnace needs to be reused. When the waste flue gas flows on the surface of the heated tube through the heating tube by the traction machine to heat the cold air entering from the outside, due to the high temperature of the waste flue gas and the short residence time when passing through the heating tube under the traction flow of the traction machine, it is easy for the waste flue gas to flow out before the temperature in the waste flue gas is completely transferred to the heating tube, thereby affecting the temperature transfer speed and heat conversion efficiency in the waste flue gas and affecting the reuse rate of the waste flue gas when it flows.

[0024] Furthermore, a fixing ring is fixedly connected to the outer surface of the heat conducting pipe inside the main body, and a plurality of balls are rotatably connected to the top of the fixing ring;

[0025] Wherein, the outer surface of the heat conducting pipe is rotatably connected to two rotating rings;

[0031] Furthermore, the pulling assembly includes a right-angle plate fixedly connected to a side wall away from the air intake duct guide plate, and two short shafts are fixedly connected to one side of the right-angle plate close to the middle of the main body.

[0032] Further, the reflux assembly includes a stepped frame fixedly connected to the outer surface of the central shaft;

[0034] Furthermore, the auxiliary assembly includes two spherical rods rotatably connected to the side wall of the air inlet pipe guide plate, and an arc-shaped elastic plate is rotatably connected between the two spherical rods;

[0035] There is spherical rotation between the spherical rod and the arc-shaped elastic plate;

[0036] The side of the arc-shaped elastic plate close to the flip plate is rotatably connected to a vertical plate, and the vertical plate is fixedly connected to the top inner wall of the air intake pipe;

[0037] Among them, the longest bending plate is slidingly connected between the two short shafts.

[0038] The present invention has the following beneficial effects:

[0039] 1. The present invention, through the push assembly and the reflux assembly, when the guide plate slides downward, the sliding of the guide plate drives the spherical rod to rotate on the surface of the central axis through the right-angle plate. At the same time, the three curved plates will rotate after being directly contacted by the airflow. When the three curved plates rotate, the three curved plates will be stacked under the obstruction of the ladder frame. When the airflow hits the three unfolded curved plates and generates reflux, the longest curved plate can guide the smoke to reflux to the middle of the main body, forming the first return flow, and then The remaining two curved plates can cause the flue gas to reflux two or three times respectively. By guiding the waste flue gas to reflux into the main body, the residence time of the waste flue gas at multiple heat pipes can be increased, so that the heat in the waste flue gas can fully contact and heat the heat pipes, thereby reducing the situation where the waste flue gas flows out before the temperature in the waste flue gas is completely transferred to the heat pipes due to the short contact time with the heat pipes during flow, thereby improving the temperature transfer speed and heat conversion efficiency in the waste flue gas, and thus enhancing the reuse rate of the waste flue gas during flow.

[0040] 2. The present invention uses the heat conduction component and the cleaning component. When the air flow flows and passes through the heat conduction pipe, the flow of the air flow and the impurities therein will act on the thin plate and periodically generate vortex shedding behind the heat conduction pipe, forming a Karman vortex street effect, which can make the thin plate resonate and swing under the action of the alternating vortex. The swing of the thin plate will drive the two thin plates and the scraper to swing synchronously. When the scraper swings, it will scrape off the dust particles attached to the surface of the heat conduction pipe. By cleaning the dust on the surface of the heat conduction pipe, it can reduce the dust particles in the exhaust gas that adhere to the surface of the heat conduction pipe during flow, affecting the heat transfer when the heat in the gas is transferred to the heat conduction pipe, thereby ensuring the stable transfer of heat in the exhaust gas and improving the heat transfer efficiency of the exhaust gas during flow.

[0041] 3. The present invention, through the push component and the return component, when the airflow flows to the recess on the guide plate, the airflow will be guided by the guide plate recess to converge obliquely upward, and the oblique upward guidance of the gas by the curved plate can make the gas drive the cleaned dust particles to flow backward under the influence of the induced draft fan when it flows. At the same time, the airflow flowing obliquely upward can further drive the flow of parallel airflow and act on the thin plate when it flows, thereby ensuring the flow force of the airflow. By driving the flow of the cleaned dust, the secondary flying of dust particles in the main body during heat transfer and airflow flow can be reduced, thereby further enhancing the flow of airflow and the cleaning efficiency of the scraper.

[0042] 4. The present invention, through the auxiliary components and the heat-conducting components, forms a certain inclination when the arc-shaped elastic plate rotates downward. At this time, the inclined arc-shaped elastic plate can change the flow path of the waste smoke flowing in the main body to produce a downward oblique path. When the airflow flows under the guidance of the arc-shaped elastic plate, it will collide with the gas flowing back when the curved plate is guided behind the multiple heat-conducting pipes. At this time, the two gases colliding with each other can be dispersed when colliding. The collision and dispersion of the two airflows can reduce the impact of the airflow on the normal flow of the airflow on the surface of the heat-conducting pipe when the airflow is guided back by the curved plate, causing the thin plate to be affected and difficult to rotate. By dispersing the colliding airflow during reflux, the reflux intensity of the gas reflux can be weakened, thereby ensuring the normal and stable flow of the waste smoke.

[0043] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] The shaking mechanism 2 includes a flip plate 201 rotatably connected to the inside of the main body 1, and the shaking mechanism 2 includes:

[0067] The pushing component 21 is installed on the side wall of the flip plate 201;

[0068] The pulling component 22 is installed inside the main body 1 .

[0069] The auxiliary mechanism 3 includes a central shaft 301 fixedly connected to the inside of the main body 1, and the auxiliary mechanism 3 includes:

[0070] A reflux assembly 31 is mounted on the outer wall of the central shaft 301;

[0071] The auxiliary component 32 is installed on the side wall of the pushing component 21 .

[0072] The conveying member includes a hollow box 111 fixedly connected to the top of the main body 1. The side of the hollow box 111 close to the air inlet pipe 101 is fixedly connected to the air outlet pipe 112, and the side of the hollow box 111 away from the air outlet pipe 112 is fixedly connected to the air inlet pipe 113.

[0073] The fixed assembly 11 includes a blower 114 fixedly connected to the end of the air inlet pipe 113 away from the hollow box 111;

[0074] A conical cylinder is fixedly connected to the inside of the air inlet pipe 101. First, the air inlet pipe 101 is connected to the hot air furnace, and the blower 114 is placed on the ground. Then, the blower 114 is connected to the subsequent processing equipment. After that, the end of the main body 1 away from the air inlet pipe 101 is connected to the induced draft fan. At the same time, the air outlet pipe 112 is connected to the equipment that needs to be utilized by heat.

[0075] The heat-conducting assembly 12 includes several heat-conducting pipes 121 fixedly connected to the top inner wall of the hollow box 111. The bottom of the heat-conducting pipe 121 passes through the top inner wall of the main body 1 and is fixedly connected to the bottom inner wall of the main body 1. When the blower 114 is working, the external cold air will be transported into the hollow box 111 and flow. At this time, the flow of cold air will pass over the heat-conducting pipe 121 and absorb the heat on the heat-conducting pipe 121 and flow outward through the air outlet pipe 112.

[0076] A fixing ring 122 is fixedly connected to the outer surface of the heat conducting pipe 121 inside the main body 1, and a plurality of balls are rotatably connected to the top of the fixing ring 122;

[0077] The outer surface of the heat pipe 121 is rotatably connected to two rotating rings 123;

[0078] The rotating ring 123 at the bottom contacts a number of balls;

[0079] A thin plate 131 is fixedly connected between the two rotating rings 123 , and a scraper 132 is fixedly connected between the two rotating rings 123 .

[0080] The pushing assembly 21 includes two oblique rods 211 fixedly connected to the end of the flip plate 201 away from the air inlet pipe 101, and three guide plates 212 are provided at the bottom of the two oblique rods 211;

[0081] Among them, a connecting plate is fixedly connected between the two guide plates 212, and an electric push rod is fixedly connected to the bottom of the middle guide plate 212;

[0082] The bottom of the guide plate 212 is fixedly connected to a return spring, and the bottom of the return spring is fixedly connected to the bottom inner wall of the main body 1. The inside of the guide plate 212 is fixedly connected to the limit block 213. When the gas flows rapidly through the conical cylinder, the flow force of the gas will impact the surface of the flip plate 201, causing the flip plate 201 to rotate downward after being impacted. When the flip plate 201 rotates downward, it will drive the two inclined rods 211 to rotate synchronously.

[0083] The pulling assembly 22 includes a right-angle plate 221 fixedly connected to the side wall of the guide plate 212 away from the air intake pipe 101. Two short shafts are fixedly connected to one side of the right-angle plate 221 close to the middle of the main body 1. The sliding of the flow plate 212 drives the spherical rod 321 to rotate on the surface of the central axis 301 through the right-angle plate 221.

[0084] The reflux assembly 31 includes a stepped frame 311 fixedly connected to the outer surface of the central shaft 301;

[0085] Among them, the outer surface of the central axis 301 is rotatably connected to three curved plates 312, and the three curved plates 312 are in a stacked state. At the same time, the three curved plates 312 will rotate after being directly contacted by the airflow. When the three curved plates 312 rotate, the three curved plates 312 will be stacked under the obstruction of the step frame 311.

[0086] The auxiliary component 32 includes two spherical rods 321 rotatably connected to the side wall of the guide plate 212 away from the intake pipe 101, and an arc-shaped elastic plate 322 is rotatably connected between the two spherical rods 321;

[0087] There is spherical rotation between the spherical rod 321 and the arc-shaped elastic plate 322;

[0088] The side of the arc-shaped elastic plate 322 close to the flip plate 201 is rotatably connected to a vertical plate, and the vertical plate is fixedly connected to the top inner wall of the air inlet pipe 101;

[0089] Among them, the longest curved plate 312 is slidably connected between the two short shafts. The downward movement of the guide plate 212 will drive the arc-shaped elastic plate 322 to produce a downward rotation and form a certain arc through the two spherical rods 321. When the arc-shaped elastic plate 322 rotates downward, it will form a certain inclination. At this time, the inclined arc-shaped elastic plate 322 can change its flow path when the waste smoke flows in the main body 1 to produce a downward oblique path.

[0090] When in use, first connect the air inlet pipe 101 to the hot blast furnace, and place the blower 114 on the ground, then connect the blower 114 to the subsequent processing equipment, then connect the end of the main body 1 away from the air inlet pipe 101 to the induced draft fan, and at the same time, connect the air outlet pipe 112 to the equipment that needs to be reused by heat, then start the external induced draft fan and blower 114, and the induced draft fan will absorb the waste smoke in the hot blast furnace through the air inlet pipe 101 when working. After flowing through the main body 1, the heat in the waste flue gas will be transferred to the heat conduction pipe 121. At the same time, when the blower 114 is working, the external cold air will be transported to the hollow box 111 and flow. At this time, the flow of cold air will pass over the heat conduction pipe 121 and absorb the heat on the heat conduction pipe 121 and flow outward through the air outlet pipe 112. The waste flue gas after heat conduction in the main body 1 will flow to the subsequent processing equipment through the induced draft fan, completing the recycling of the waste flue gas.

[0091] When the exhaust gas flows into the main body 1 under the suction of the induced draft fan, the flowing gas will pass through the conical cylinder in the air inlet pipe 101 and accelerate to flow into the interior of the main body 1. At the same time, the flowing gas will be guided by the conical ring 102 and quickly flow to the middle of the main body 1. When the gas flows quickly through the conical cylinder, the electric push rod at the bottom of the guide plate 212 is started. At this time, the guide plate 212 will move downward under the drive of the electric push rod. At the same time, the flow force of the gas will impact the surface of the flip plate 201, causing the flip plate 201 to be affected by the After the impact, the gas will rotate downward. At this time, the gas will flow in the middle of the main body 1 under the guidance of the flip plate 201. When the guide plate 212 slides downward, the sliding of the guide plate 212 drives the spherical rod 321 to rotate on the surface of the central axis 301 through the right-angle plate 221. At the same time, the three curved plates 312 will also rotate after being directly contacted by the airflow under the flow of the airflow. When the three curved plates 312 rotate, the three curved plates 312 will be blocked by the ladder frame 311 and present a stacked arrangement, such as Figure 8The state in the middle, when the waste flue gas continues to flow in the main body 1, the flow of the waste flue gas will be guided by the curved structure at the front end of the three curved plates 312 to produce a backflow situation. When the airflow encounters the three expanded curved plates 312 and produces a backflow, the longest curved plate 312 can guide the flue gas to flow back to the middle position of the main body 1, forming the first return flow, and then the remaining two curved plates 312 can respectively cause the flue gas to produce two or three backflows. By guiding the waste flue gas to reflux into the main body 1, the residence time of the waste flue gas at the multiple heat pipes 121 can be increased, so that the heat in the waste flue gas can fully contact and heat the heat pipes 121, thereby reducing the situation where the waste flue gas flows out due to the short contact time with the heat pipes 121 when it is flowing, thereby improving the temperature transfer speed and heat conversion efficiency in the waste flue gas, and thus enhancing the reuse rate of the waste flue gas when it flows.

[0092] When the exhaust gas passes through the conical cylinder and conical ring 102 in the air inlet pipe 101, the rapid flow in the middle of the main body 1 will impact the outer wall of multiple heat-conducting pipes 121 and flow. When the air flow flows and passes through the heat-conducting pipe 121, the flow of the air flow and its internal impurities will act on the thin plate 131 and periodically generate vortex shedding behind the heat-conducting pipe 121, forming a Karman vortex street effect, which can make the thin plate 131 resonate and swing under the action of the alternating vortex. At this time, the thin plate 131 appears under the action of the alternating vortex. When swinging, the swing of the thin plate 131 will drive the two thin plates 131 and the scraper 132 to swing synchronously. When the scraper 132 swings, it will scrape off the dust particles attached to the surface of the heat pipe 121. By cleaning the dust on the surface of the heat pipe 121, it can reduce the dust particles in the exhaust gas from adhering to the surface of the heat pipe 121 during flow, affecting the heat transfer when the heat in the gas is transferred to the heat pipe 121, thereby ensuring the stable transfer of heat in the exhaust gas and improving the heat transfer efficiency of the exhaust gas during flow.

[0093] When the guide plate 212 moves downward, the flow of waste smoke will flow through the surface of the guide plate 212. At this time, the flow of gas will be guided by the limit block 213 to produce an oblique upward flow. In addition, when the airflow flows to the depression on the guide plate 212, the airflow will be guided by the depression of the guide plate 212 to converge obliquely upward. The oblique upward guidance of the gas by the curved plate 312 can make the gas drive the cleaned dust particles to flow backward under the influence of the induced draft fan. At the same time, the airflow flowing obliquely upward can further drive the flow of parallel airflow and act on the thin plate 131 when it flows, thereby ensuring the flow force of the airflow. By driving the flow of the cleaned dust, the secondary flying of dust particles in the main body 1 during heat transfer and airflow can be reduced, thereby further enhancing the flow of airflow and the cleaning efficiency of the scraper 132.

[0094] When the guide plate 212 slides downward, the downward movement of the guide plate 212 will drive the arc-shaped elastic plate 322 to rotate downward and form a certain arc through the two spherical rods 321. When the arc-shaped elastic plate 322 rotates downward, it will form a certain inclination. At this time, the inclined arc-shaped elastic plate 322 can change its flow path when the exhaust gas flows in the main body 1 to produce an oblique downward path. When the airflow flows under the guidance of the arc-shaped elastic plate 322, it will collide with the gas flowing back when guided by the curved plate 312 behind the multiple heat pipes 121. At this time, the two gases colliding with each other can be dispersed when colliding. The collision and dispersion of the two airflows can reduce the impact of the airflow on the normal flow of the airflow on the surface of the heat pipe 121 when it is guided by the curved plate 312, causing the thin plate 131 to be affected and difficult to rotate. By dispersing the colliding airflow during reflux, the reflux intensity of the gas reflux can be weakened, thereby ensuring the normal and stable flow of the exhaust gas.
