Description

Technical Field

[0001] The invention relates to the technical field of single carbonization chamber pressure control devices, in particular to a single carbonization chamber raw gas pressure control device. Background Art

[0002] The pressure of the single carbonization chamber of the coke oven is an important parameter in the coking process of the coking plant. If the pressure of the single carbonization chamber is too high, it will not only damage the relative equipment, but also cause the leakage and escape of raw coal gas, thereby polluting the environment. If the pressure of the single carbonization chamber is too low, air will enter the single carbonization chamber, thereby causing the combustion of coke in the single carbonization chamber, which will not only affect the coking quality, but also cause damage to the coke oven equipment. Therefore, in the coking process, the pressure of the single carbonization chamber needs to be timely regulated to ensure safe production and coking quality.

[0003] At present, in the process of regulating the pressure of a single carbonization chamber, a commonly used method is generally to manually open and close the riser on time and switch the ammonia water to achieve pressure regulation of the single carbonization chamber. However, this regulation method is more dependent on manual operation. However, manual operation is not only labor-intensive, but also prone to certain randomness leading to operational errors. In addition, in the process of switching ammonia water for regulation, there is a lack of collection and guidance of ammonia water, which leads to a large area of ​​erosion by ammonia water, thereby affecting the service life of related components. In this regard, the present application specifically proposes a single carbonization chamber raw gas pressure control device. Summary of the invention

DETAILED DESCRIPTION

[0018] The following is combined with Figure 1-7 The specific implementation modes of the present invention are further described in detail.

[0019] Embodiment 1, the technical solution is that during the use of the present application, the upper end of the elbow 1 is connected to the flange of the riser of the single carbonization chamber, and then the raw gas in the single carbonization chamber can enter the elbow 1 through the riser, so as to facilitate the pressure regulation of the single carbonization chamber. The ammonia water nozzle 2 of the present application is used to spray low-pressure circulating ammonia water, which can quickly cool the raw gas entering the elbow 1 and prevent the smoke phenomenon; during coking, the air pressure measuring device 4 transmits the pressure value in the elbow 1 to the upper computer in real time, and the upper computer controls the operation of the lifting device 19 through the received pressure value, and then the lifting rod 11 can be driven to move vertically through the lifting device 19, and then the sealing body 13 connected to the lifting rod 11 through the mounting rod 12 will also move vertically accordingly, and then the flow of raw gas can be adjusted to achieve the purpose of regulating the pressure of the single carbonization chamber. The present application has a simple structure, is easy to use, and has strong practicality. The present application is provided with an overflow groove 8 and a splash-proof baffle 14, so as to receive and guide the ammonia sprayed by the ammonia nozzle 2, so that the ammonia can flow to the sewage pipe 16 through the discharge pipe 15 for release, thereby preventing the ammonia from splashing in the pipeline and causing corrosion to the elbow 1 and the gas collecting pipe 5 and other components, thereby affecting the service life of the present application.

[0020] Embodiment 2, based on embodiment 1, specifically, when the present application is in the coal loading period of coking, a large amount of smoke dust is generated by carbonization and enters the elbow 1 through the riser, thereby causing the pressure in the elbow 1 to increase sharply, and the air pressure measuring device 4 can monitor the pressure value in the elbow 1 in real time and transmit it to the host computer, the host computer compares the pressure value transmitted by the air pressure measuring device 4 with the set value and determines that the pressure is higher than the set value, the host computer controls the ammonia water nozzle 2 to release the high-pressure ammonia water, and at the same time the host computer also controls the driving motor 33 of the lifting device 19 to rotate forward, and the driving motor 33 rotates forward to drive the rotating connection at the bottom The screw rod 31 between the seat 28 and the support plate 30 rotates forward, and the forward rotation of the screw rod 31 will drive the driving rod 32 to slide down along the vertical rod 29, and then the lifting rod 11 fixedly connected to the driving rod 32 will also move downward along the mounting sleeve 10, and then the mounting rod 12 together with the sealing body 13 will also move downward, and then the sealing body 13 will be separated from the blockage of the lower end of the gas guide cylinder 6, and the bottom opening of the gas guide cylinder 6 is completely open, and the ammonia water can be quickly discharged from the bottom of the gas guide cylinder 6. At this time, the flow rate of the raw gas is the largest, which is convenient for quickly introducing the gas in the elbow 1 into the gas collecting pipe 5, and then the pressure in the elbow 1, that is, the single carbonization chamber, can be quickly restored.

[0021] When the present application is coking, the pressure in the single carbonization chamber is likely to be lower than the set value. When the air pressure measuring device 4 measures that the pressure in the bend pipe 1 (i.e., the single carbonization chamber) is lower than the set value, the air pressure measuring device 4 sends the measured value to the host computer. The host compares the received data with the set value and determines that the pressure is lower than the set value. The host computer controls the driving motor 33 of the lifting device 19 to reverse. The reverse rotation of the driving motor 33 will drive the driving rod 32 to move upward along the vertical rod 29, and then the lifting rod 11 will move upward with the driving rod 32, and the sealing body 13 detachably connected to the lifting rod 11 will also move upward. Move upward and insert the lower end of the gas guide cylinder 6, and then seal the lower end of the gas guide cylinder 6. At this time, the ammonia water can only overflow through the through groove 7, and the raw coal gas in the elbow 1 can only flow to the gas collecting pipe 5 through the through groove 7. Further, as the sealing body 13 continues to move upward, the sealing body 13 can also seal the through groove 7, and then can further limit the amount of raw coal gas passing through. By limiting the flow of gas from the elbow 1 to the gas collecting pipe 5 in this way, the pressure in the elbow 1 (i.e., the single carbonization chamber) can be quickly restored to be regulated, so that the gas pressure in the single carbonization chamber is restored to the set value.

[0022] When the riser cover is in an open state at the end of the coking stage of the present application, a water seal should be formed inside the pipe to prevent air from entering the gas collecting pipe 5 and to prevent the raw coal gas in the gas collecting pipe 5 from overflowing. Specifically, the upper computer controls the driving motor 33 to reverse, and the driving motor 33 reverses to drive the driving rod 32 to move upward along the vertical rod 29, and then the lifting rod 11 will move upward with the driving rod 32, and the sealing body 13 detachably connected to the lifting rod 11 will also move upward and insert into the gas guide cylinder 6. As the sealing body 13 continues to move upward, the sealing body 13 inserted into the gas guide cylinder 6 will also completely block the through groove 7. At this time, the ammonia water above the sealing body 13 can form a water seal to prevent air from entering the gas collecting pipe 5 and prevent the raw coal gas in the gas collecting pipe 5 from overflowing.

[0023] Embodiment 3, on the basis of embodiment 2, when the sealing body 13 is in a detached state from the air cylinder 6, the ammonia water can be directly poured from the lower end of the air cylinder 6 to the splash-proof body 14, and the side wall of the splash-proof body 14 has a certain height to prevent the poured ammonia water from splashing elsewhere; when the sealing body 13 blocks the lower end of the air cylinder 6 and the ammonia water can only overflow through the groove 7, the ammonia water will first overflow to the overflow groove 8, and then enter the splash-proof body 14 through the overflow hole 9. The side wall of the splash-proof body 14 has a certain height to prevent the ammonia water from splashing to the outside when falling from the overflow hole 9. Through the above-mentioned arrangement, the ammonia water can be guided to gather at the splash-proof body 14, which greatly reduces the affected area of ​​the ammonia water and the corrosion effect of the ammonia water. In addition, the ammonia water at the splash-proof body 14 can also flow to the drain pipe 16 through the discharge pipe 15, and the ammonia water can be discharged by opening the drain pipe 16. In order to further reduce the influence of ammonia water, a cleaning nozzle 3 is arranged at the bend pipe 1, and the cleaning nozzle 3 releases high-pressure clean water to clean the part affected by the ammonia water.

[0024] Embodiment 4, on the basis of embodiment 3, the left end of the gas collecting pipe 5 is flange-connected with an end cover 18, and the flange connection form facilitates the disassembly of the end cover 18; the left end of the mounting rod 12 is connected to the sealing body 13 through the cooperation of the first screw part 22, the first nut 24 and the first connecting hole 23, and the right end of the mounting rod 12 is connected to the lifting rod 11 through the cooperation of the second screw part 25, the second nut 27 and the second connecting hole 26, which is also convenient for disassembly, and then the end cover 18 can be opened to replace and maintain the corresponding parts. The sealing body 13 is composed of a sealing seat 20 and a sealing gasket 21, and the outer edge of the sealing body 13 can slide against the inner wall of the air guide cylinder 6 to form a seal.
