Description

Technical Field

[0001] The invention relates to the technical field of converter fume separation devices, and in particular to an explosion-proof device for a converter fume waste heat boiler. Background Art

[0002] The waste heat boiler for converter flue gas treatment is a device specially designed to recover the heat of the high-temperature flue gas generated by the converter during the steel production process. A large amount of high-temperature flue gas will be generated during the converter steelmaking process. These flue gases contain a large amount of heat. If not utilized, this part of the energy will be wasted and will also cause pollution to the environment. Therefore, the use of waste heat boilers can effectively recover this part of the heat and convert it into useful steam or hot water for power generation, heating or other industrial purposes, thereby improving energy utilization efficiency and reducing environmental pollution. As a high-pressure equipment, the waste heat boiler requires strict safety measures during operation to prevent potential explosion risks. For this reason, it is very necessary to install effective explosion-proof devices. Common waste heat boiler explosion-proof devices include safety valves, etc.

[0003] During the use of the waste heat boiler, if the water supply system fails or the operating error causes the water supply to be reduced or completely stopped, and the burner continues to heat, the heat in the flue gas in the boiler cannot be transferred to the outside in time, which will cause the volume of the flue gas to fail to shrink in time, thereby causing the pressure to rise rapidly. When the existing safety valve relieves the pressure of the boiler, the degree of opening of the safety valve is related to the air pressure in the boiler. It cannot be directly opened to the maximum extent when the air pressure in the boiler rises rapidly to quickly relieve the pressure of the boiler. This will cause the boiler to be in a high-pressure state for a long time, increasing the risk of boiler explosion. Summary of the invention

DETAILED DESCRIPTION

[0049] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0050] An explosion-proof device for a converter flue gas waste heat boiler, such as Figure 1-Figure 3 As shown, it includes: a boiler 1, which is connected to a pressure relief shell 2, and the pressure relief shell 2 is provided with an air inlet and an air outlet; a first blocking ring 3, which is fixed in the pressure relief shell 2; a sealing member 4, which is slidably connected in the pressure relief shell 2, and the sealing member 4 is slidably connected to the first blocking ring 3, and a first spring is arranged between the sealing member 4 and the first blocking ring 3, and the sealing member 4 is matched with the air inlet of the pressure relief shell 2 for blocking, and a downward conical protrusion is arranged in the middle of the lower side of the sealing member 4; a first pipe 5, which is connected to one side of the pressure relief shell 2, and the other side of the pressure relief shell 2 is connected to a second pipe 6, and the first pipe 5 and the second pipe 6 are commonly connected to a first adjusting shell 7; a blocking column 8, which is slidably connected in the first adjusting shell 7, and the first pipe 5 and the second pipe 6 are both matched with the blocking column 8 for blocking.

[0051] In the above scheme, the purpose is to increase the distance that the sealing member 4 moves, so as to increase the speed of the device to relieve the pressure of the gas in the boiler 1. The pressure relief shell 2 is located on the upper side of the boiler 1, the air inlet of the pressure relief shell 2 is located on its lower side, and the air outlet of the pressure relief shell 2 is located on its right side. The sealing member 4 is composed of a disc on the upper side, a round rod in the middle, and a plug at the lower part. The round rod part of the sealing member 4 passes through the first blocking ring 3 and cooperates with it in a sliding seal. The first spring is located between the plug part of the sealing member 4 and the first blocking ring 3. A rubber ring is provided at the lower edge of the plug part of the sealing member 4. The rubber ring is squeezed together by the plug part of the sealing member 4 and the air inlet of the pressure relief shell 2 to achieve sealing. A downward conical protrusion is provided in the middle of the plug part of the sealing member 4, so as to guide the high-pressure gas blown from the air inlet of the pressure relief shell 2. In order to prevent high-pressure gas mixed with particulate impurities from blowing directly to the rubber ring, thereby extending the service life of the rubber ring, the disc part and the round rod part of the sealing member 4, the first blocking ring 3 and the pressure relief shell 2 cooperate with each other to form a cavity, the second pipe 6 is connected to the cavity, and the first pipe 5 is connected to the air inlet of the pressure relief shell 2. When the air inlet of the pressure relief shell 2 is connected to the cavity, the area of ​​the sealing member 4 subjected to the gas pressure increases. When the air pressure in the boiler 1 is the same, the larger the area of ​​the sealing member 4 in contact with the gas in the boiler 1, the greater the thrust of the gas on the sealing member 4, so that the sealing member 4 can push the first spring to undergo a greater deformation to quickly release the pressure in the boiler 1.

[0052] Further, such as Figure 1-Figure 3 As shown, it also includes: a sliding member 9, which is slidably connected in the first adjusting shell 7 and fixedly connected to the blocking column 8, the first adjusting shell 7 is provided with a first slide groove 701 and a second slide groove 702, the blocking column 8 is located in the first slide groove 701, the sliding member 9 is composed of a disc and a round rod, and the disc part of the sliding member 9 is located in the second slide groove 702; the second adjusting shell 10 is arranged on one side of the first pipeline 5, the second adjusting shell 10 is slidably connected with an adjusting column 11, a second spring is arranged between the adjusting column 11 and the second adjusting shell 10, and the second adjusting shell 10 is connected with the second slide groove 702; the blocking rod 901 is fixedly connected to the sliding member 9, the pressure relief shell 2 is provided with a pressure relief port, and the blocking rod 901 cooperates with the pressure relief port of the pressure relief shell 2 to seal.

[0053] In the above scheme, the purpose is to move and reset the blocking column 8. The round rod portion of the sliding member 9 is fixedly connected to the blocking column 8, and the second adjustment housing 10 and the second slide groove 702 are filled with liquid, so that when the adjustment column 11 moves relative to the second adjustment housing 10, the sliding member 9 is hydraulically driven to move, and the second spring between the adjustment column 11 and the second adjustment housing 10 is used to reset the adjustment column 11. The blocking rod 901 is composed of a U-shaped rod and a disc, and the diameter of the pressure relief port of the pressure relief housing 2 is larger than the diameter of the U-shaped rod portion of the blocking rod 901, and smaller than the diameter of the disc portion of the blocking rod 901.

[0054] Further, such as Figure 2 and Figure 3 As shown, it also includes: a trigger member 12, having two symmetrically distributed, both slidably connected to the first pipe 5, and the two trigger members 12 divide the first pipe 5 into three parts: a first part 501, a second part 502 and a third part 503; a second blocking ring 13, having two symmetrically distributed, both fixedly connected to the first pipe 5, and the two second blocking rings 13 are respectively located on the back sides of the two trigger members 12, and a tension spring is arranged between the trigger member 12 and the adjacent second blocking ring 13; a connecting member 14, having two symmetrically distributed, respectively fixedly connected to adjacent trigger members 12, the connecting member 14 is slidably connected to the first pipe 5, and the second adjustment shell 10 and the adjustment column 11 are respectively fixedly connected to the adjacent connecting members 14.

[0055] In the above scheme, the purpose is to monitor the change of air pressure in the boiler 1, and when the air pressure in the boiler 1 rises sharply, the blocking column 8 is driven to release the blocking of the first pipe 5 and the second pipe 6. The triggering members 12 are symmetrically distributed up and down, and the back sides of the two triggering members 12 are provided with grooves for accommodating the tension spring and preventing the first pipe 5 from leaking when the triggering members 12 move. The third part 503 is connected to the first adjustment housing 7, and the first part 501 is connected to the air inlet of the pressure relief housing 2. The second blocking ring 13 is used to provide a fixed position for the tension spring and enable the first pipe 5 to be ventilated normally. The tension spring between the triggering member 12 and the second blocking ring 13 is used to reset the triggering member 12. The first pipe 5 is provided with a through hole for the connecting member 14 to connect the adjusting column 11 or the second adjusting housing 10 with the adjacent triggering member 12. The connecting member 14 slides in the adjacent through hole on the first pipe 5, and the triggering member 12 cooperates with the adjacent through hole on the first pipe 5 to prevent the first pipe 5 from leaking.

[0056] Further, such as Figure 2 and Figure 3 As shown, it also includes: a third pipe 15, which is fixedly connected to the first pipe 5, and the third pipe 15 connects the first part 501 and the third part 503; a fourth pipe 16, which is connected to the third pipe 15, and the fourth pipe 16 is connected to the second part 502, and the diameter of the fourth pipe 16 is smaller than the diameter of the third pipe 15.

[0057] In the above scheme, the two triggering members 12 are intended to move when the pressure in the boiler 1 increases sharply. The third pipe 15 connects the first part 501 and the third part 503, so that the smoke in the boiler 1 can bypass the two triggering members 12 and enter the cavity formed by the disc part and the round rod part of the blocking member 4, the first blocking ring 3 and the pressure relief shell 2. When the smoke in the boiler 1 enters the cavity, the contact area between the blocking member 4 and the smoke increases, so that the upward pressure on the blocking member 4 increases to overcome the downward pressure of the first spring, thereby causing the pressure in the boiler 1 to drop rapidly. When the pressure in the boiler 1 increases rapidly, because the diameter of the fourth pipe 16 is too small, the speed of the increase of the air pressure in the second part 502 is smaller than the speed of the increase of the air pressure in the first part 501 and the third part 503. In this way, when the pressure in the boiler 1 increases rapidly, the two triggering members 12 can move toward each other to drive the blocking column 8 to release the blockage of the first pipe 5 and the second pipe 6.

[0058] Further, such as Figure 3 As shown, it also includes: a limit column 17, the adjusting column 11 is provided with a third slide groove 1101, the limit column 17 is slidably connected in the third slide groove 1101, and the second adjusting shell 10 is provided with a limit groove that cooperates with the limit column 17; a first sliding plate 18 is slidably connected in the third slide groove 1101, and a third spring is provided between the first sliding plate 18 and the limit column 17.

[0059] In the above scheme, the sensitivity of the relative movement between the second adjustment housing 10 and the adjustment column 11 is reduced. The limit column 17 is composed of a hemisphere and a cylinder, and the hemisphere of the limit column 17 cooperates with the limit groove on the second adjustment housing 10. When the adjustment column 11 moves relative to the second adjustment housing 10, it is necessary to overcome the resistance of the limit column 17 to it first. The third spring between the first sliding plate 18 and the limit column 17 is always in a compressed state, thereby maintaining the pressure of the limit column 17 on the upper limit groove of the second adjustment housing 10, thereby generating resistance.

[0060] Further, such as Figure 3 and Figure 4 As shown, it also includes: a second sliding plate 19, the adjusting column 11 is provided with a fourth sliding groove 1102, the second sliding plate 19 is slidably connected in the fourth sliding groove 1102, and the fourth sliding groove 1102 is connected to the third sliding groove 1101; a threaded rod 20, which is threadedly connected to the adjusting column 11, and the threaded rod 20 is rotatably connected to the second sliding plate 19.

[0061] In the above scheme, the compression amount of the third spring between the first sliding plate 18 and the limiting column 17 is adjusted, thereby changing the sensitivity of the relative movement of the second adjustment housing 10 and the adjustment column 11. Liquid is filled in the fourth slide groove 1102 and the third slide groove 1101, so that when the second sliding plate 19 moves, the first sliding plate 18 is driven to move by hydraulic means, and when the threaded rod 20 rotates, it moves up and down relative to the adjustment column 11, thereby driving the second sliding plate 19 to move.

[0062] Working process: when the air pressure in the boiler 1 increases rapidly, the gas in the boiler 1 enters the air inlet of the pressure relief shell 2, then enters the first part 501, and then enters the third part 503. At this time, due to the small diameter of the second pipe 6, the air pressure in the second part 502 cannot be increased to the same as the air pressure in the boiler 1 in time. At this time, the two trigger members 12 are subjected to different air pressures on both sides, and the two trigger members 12 move toward each other, and each drives the second regulating shell 10 and the regulating column 11 to move through the connecting member 14. The second regulating shell 10 and the regulating column 11 move toward each other, and the liquid in the second regulating shell 10 is pressed into the second chute 702. The increase in liquid in the second chute 702 pushes the sliding member 9 to move, and the sliding member 9 drives the blocking rod 901 to move. The blocking rod 901 blocks the pressure relief port on the pressure relief shell 2. At the same time, the sliding member 9 drives the blocking column 8 to move, and the blocking column 8 releases the first pipe 5 and The blocking of the second pipeline 6 allows the gas in the boiler 1 to enter the cavity formed by the disc and round rod parts of the sealing member 4, the first blocking ring 3 and the pressure relief shell 2 through the second pipeline 6, thereby moving the sealing member 4 upward to release the blockage of the air inlet of the pressure relief shell 2, and the gas in the boiler 1 enters from the air inlet of the pressure relief shell 2, and then is discharged from the air outlet of the pressure relief shell 2. When the pressures in the first part 501, the second part 502 and the third part 503 are restored to balance, the two trigger members 12 are reset under the action of adjacent tension springs, and when the trigger member 12 is reset, the blocking column 8 is driven to reset, and when the blocking column 8 is reset, the blocking rod 901 is driven to reset through the sliding member 9. When the blocking rod 901 is reset, the blockage of the pressure relief port on the pressure relief shell 2 is released, so that the cavity formed by the disc and round rod parts of the sealing member 4, the first blocking ring 3 and the pressure relief shell 2 is connected to the outside, thereby restoring the pressure therein.

[0063] Further, such as Figure 1 , Figure 2 and Figure 5 As shown, it also includes: a mounting shell 21, which is connected to the air outlet of the pressure relief shell 2, and the mounting shell 21 is provided with a collecting groove; a filter element 22, which is arranged in the mounting shell 21, and a side of the filter element 22 close to the pressure relief shell 2 is provided with an inclined surface; there are a plurality of guide plates 23, which are all fixedly connected to the mounting shell 21, and the guide plates 23 are located in the collecting groove of the mounting shell 21.

[0064] In the above scheme, the purpose is to filter the smoke exhausted from the boiler 1 to prevent the smoke exhausted from the boiler 1 from polluting the environment. The collection tank is located on the side of the mounting shell 21 close to the filter element 22, so that the smoke filtered by the filter element 22 can fall directly into the collection tank, and the inclined surface on the filter element 22 faces the collection tank, so that the smoke attached thereto can fall into the collection tank more easily. The guide plates 23 are all arranged in an inclined manner, and the side of the guide plates 23 located in the middle is lower than the side located outside, and the side of the guide plates 23 located outside is fixedly connected to the mounting shell 21, so that the smoke will not be blown out after falling into the collection tank of the mounting shell 21. At the same time, a discharge port can be set at the collection tank of the mounting shell 21, so that the collected smoke can be discharged when the collection tank of the mounting shell 21 is full of smoke.

[0065] Further, such as Figure 5 and Figure 6 As shown, it also includes: a rotating shaft 24, which is rotatably connected to the mounting shell 21, and a plurality of wind-receiving shells 25 are fixedly connected to the rotating shaft 24 at circumferential intervals; elastic rods 26, the number of which is consistent with the number of wind-receiving shells 25, and the elastic rods 26 are respectively fixedly connected to adjacent wind-receiving shells 25; impact balls 27, the number of which is consistent with the number of wind-receiving shells 25, and the impact balls 27 are respectively fixedly connected to adjacent elastic rods 26; a vibration plate 28, which is fixedly connected to the filter element 22, and a plurality of impact balls 27 are all squeezed and fitted with the vibration plate 28.

[0066] In the above scheme, the cleaning effect of smoke and dust attached to the filter element 22 is improved to maintain the permeability of the filter element 22 and reduce its resistance to gas. A plurality of wind receiving shells 25 are evenly distributed in the circumferential direction so that the speed of the rotating shaft 24 driven by the wind receiving shells 25 is more uniform. The wind receiving shells 25 are in the shape of a hemispherical shell, so that no matter from which direction the airflow blows, the rotating shaft 24 can be driven to rotate through the plurality of wind receiving shells 25. The wind receiving shells 25 can also be set to other shapes, as long as the wind flow blows through, the rotating shaft 24 can be driven to rotate by the wind receiving shells 25. The impact ball 27 and the vibration plate 28 can both be set to metal materials to improve the durability of both. The vibration plate 28 needs to have a certain elasticity so that when the impact ball 27 hits the vibration plate 28, the vibration plate 28 can generate vibration and transmit the vibration to the filter element 22, thereby shaking off the smoke and dust attached to the filter element 22.

[0067] Working process: when smoke enters the mounting shell 21 from the air outlet of the pressure relief shell 2, the airflow blows the wind receiving shells 25, so that several wind receiving shells 25 drive the rotating shaft 24 to rotate, and at the same time, the wind receiving shells 25 drive the adjacent elastic rods 26 to rotate, and the elastic rods 26 drive the impact ball 27 to rotate. When the impact ball 27 rotates to contact the vibration plate 28, the impact ball 27 knocks the vibration plate 28, causing the vibration plate 28 to vibrate, and the vibration plate 28 transmits the vibration to the filter element 22, and shakes off the smoke and dust attached to the surface of the filter element 22. When the smoke and dust falls, it falls into the collection groove of the mounting shell 21, and falls on the guide plate 23, and then slides down along the guide plate 23 and enters the bottom of the collection groove of the mounting shell 21. When the collection groove of the mounting shell 21 is full, the mounting shell 21 can be removed to clean the smoke and dust collected therein.

[0068] The present invention provides a thought and method. There are many methods and ways to implement the technical solution. The above is only the preferred implementation mode of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
