Description

Technical Field

[0001] This utility model relates to the field of blower technology, and in particular to a gas purification blower for coke production. Background Technology

[0002] In the coke production process, coal gas, as an important by-product, needs to be purified before it can be transported and utilized. Coal gas blowers are key equipment for achieving efficient coal gas transportation. Their main function is to drive the internal impeller to rotate through a power unit, pressurize the coal gas, and thus promote the directional flow of the coal gas in the pipeline system to meet the needs of subsequent processes.

[0003] However, since coal gas inevitably contains a small amount of impurities, such as coal dust, coke particles, tar droplets, and viscous substances like naphthalene, these impurities will gradually deposit on the inner wall of the inner shell, the surface of the impeller, and the flow channel during the operation of the blower. After long-term operation, the scale buildup on the inner wall of the inner shell and the surface of the impeller will reduce the effective flow cross-section, increase the resistance to coal gas flow, and cause the blower's air pressure and air volume to decrease, failing to meet the process requirements for coal gas delivery. Therefore, a purified coal gas blower for coke production is proposed to solve this problem. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] Gas purification blowers used in coke production include:

[0006] The housing includes an inner shell and an outer shell arranged sequentially from the inside to the outside. An air outlet pipe is fixed to the circumferential surface of the inner shell and integrally formed therewith. An air inlet pipe is integrally formed at the center of the inner shell. An annular area is formed between the inner wall of the outer shell and the outer wall of the inner shell.

[0007] The driving component is rotatably inserted into the side wall of the housing at the end away from the air inlet pipe;

[0008] Multiple cleaning components include a cleaning tube fixedly installed on the inner wall of the inner shell and communicating with the annular area, an air outlet opened on the circumferential surface of the cleaning tube, and a sealing plate slidably installed in the cleaning tube and capable of blocking the air outlet. A spring is fixedly installed between the sealing plate and the inner wall of the cleaning tube, and an air inlet pipe is fixedly inserted into the top of the outer shell.

[0009] A drain component is connected to the bottom of the inner shell.

[0010] As an improvement to the above technical solution, the sewage discharge component includes a sewage discharge pipe fixedly inserted into the bottom of the inner shell, a fixed pipe fixedly inserted into the bottom of the sewage discharge pipe, and multiple sets of sewage discharge holes opened on the circumferential surface of the fixed pipe. A rotating rod with a cavity is threaded into the bottom of the fixed pipe, and both ends of the rotating rod are provided with openings.

[0011] As an improvement to the above technical solution, an enlarged part adapted to the drain pipe is fixedly sleeved on the surface of the fixed pipe at the bottom position of the drain hole.

[0012] As an improvement to the above technical solution, the driving component includes a rotating shaft that is rotatably inserted into the center of the inner shell. One end of the rotating shaft passes through the inner shell and the outer shell in sequence and extends to the outside of the outer shell. A motor is installed at the end of the rotating shaft that extends to the outer shell. The surface of the rotating shaft and a section located inside the inner shell are provided with fan blades arranged in a ring array.

[0013] The beneficial effects of this utility model are:

[0014] By directional purging with high-temperature and high-pressure gas, sticky impurities and solid particles on the inner wall of the shell can be softened and peeled off, avoiding problems such as reduced flow cross-section and increased resistance caused by impurity accumulation. This maintains the stability of the blower's air pressure and air volume in the long term, ensuring the efficiency of gas transportation.

[0015] The cleaning component automatically opens and closes the sealing plate via pressure, completing the cleaning process without manual intervention. After cleaning, the spring drives the sealing plate to automatically reset and seal, eliminating manual operation steps, reducing the frequency and time of downtime for disassembly and cleaning, and lowering maintenance costs and labor intensity.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Gas purification blowers used in coke production include:

[0023] The housing 10 includes an inner shell 102 and an outer shell 101 arranged sequentially from the inside to the outside. An air outlet pipe 11 integrally formed therewith is fixed on the circumferential surface of the inner shell 102. An air inlet pipe 12 integrally formed at the center of the inner shell 102 is provided. An annular area is formed between the inner wall of the outer shell 101 and the outer wall of the inner shell 102.

[0024] The driving component is rotatably inserted into the side wall of the housing 10 and at the end away from the air inlet pipe 12;

[0025] Multiple cleaning components include a cleaning tube 20 fixedly disposed on the inner wall of the inner shell 102 and communicating with the annular area, an air outlet 23 opened on the circumferential surface of the cleaning tube 20, and a sealing plate 22 slidably disposed in the cleaning tube 20 and capable of blocking the air outlet 23. A spring 21 is fixedly disposed between the sealing plate 22 and the inner wall of the cleaning tube 20. An air inlet pipe is fixedly inserted into the top of the outer shell 101.

[0026] A drain component is connected to the bottom of the inner shell 102.

[0027] Specifically, when the drive unit is running, the gas enters the interior of the inner shell 102 through the air inlet pipe 12 in the center of the inner shell 102. Under the power of the drive unit, the gas is pressurized and discharged through the air outlet pipe 11 around the inner shell 102, thus completing the gas transportation function. When it is necessary to clean the inside of the blower, the air outlet pipe 11 and the air inlet pipe 12 are blocked. High-temperature gas is introduced through the air inlet pipe at the top of the outer shell 101. This gas enters the annular area between the outer shell 101 and the inner shell 102 for temporary storage. When the gas pressure in the annular area rises to a certain level, it will pressurize the interior through the cleaning pipe 20 connected to the annular area. At this time, the sealing plate 22 in the cleaning pipe 20 is subjected to gas pressure and slides against the elastic force of the spring 21. The originally blocked air outlet 23 is opened, and the high-temperature gas is ejected from the air outlet 23, which will directly act on the inner wall of the inner shell 102 and any impurities that may be attached inside. Because the high-temperature gas has a high temperature and pressure, it can heat the sticky impurities such as tar and naphthalene adhering to the inner wall of the inner shell 102, making them soften or even melt, thus reducing their adhesion. On the other hand, the high-pressure airflow can generate a strong purging force on the softened impurities and solid impurities such as coal dust and coke particles, peeling these impurities off the inner wall of the inner shell 102. The peeled impurities will sink downwards under the action of gravity and eventually collect at the bottom of the inner shell 102, where they will be discharged in time through the connected drain device, thereby completing the cleaning of the blower's interior. When the cleaning work is completed and the high-temperature gas supply is stopped, the pressure in the annular area gradually decreases. The sealing plate 22 resets under the elastic force of the spring 21, resealing the vent 23 to prevent leakage during subsequent gas transportation and ensure that the blower's normal gas transportation function is not affected. When the pressure in the annular area decreases, the elastic force of the spring 21 will push the sealing plate 22 to reset, resealing the vent 23 to prevent gas leakage from the cleaning pipe 20.

[0028] In one embodiment, the sewage discharge component includes a sewage discharge pipe 103 fixedly inserted into the bottom of the inner shell 102, a fixed pipe 104 fixedly inserted into the bottom of the sewage discharge pipe 103, and a plurality of sewage discharge holes 105 opened on the circumferential surface of the fixed pipe 104. A rotating rod 106 with a cavity is threadedly inserted into the bottom of the fixed pipe 104, and both ends of the rotating rod 106 are provided with openings.

[0029] In the initial state, coal dust, tar residue, etc. blown off by the cleaning component inside the inner shell 102 are deposited into the drain pipe 103 under the action of gravity. At this time, the side wall of the rotating rod 106 seals the drain hole 105. When centralized drainage is required, the rotating rod 106 is rotated, causing the rotating rod 106 to move downward, so that the top of the rotating rod 106 moves below the drain hole 105. Particulate impurities or viscous tar residue can be discharged through the cavity of the rotating rod 106. After the drainage is completed, the rotating rod 106 is rotated in the opposite direction to move upward and reset, and the side wall re-seals the drain hole 105, reducing the leakage of coal gas from the drainage system during normal operation and ensuring the stability of the internal pressure of the blower.

[0030] In one embodiment, an enlarged portion adapted to the drain pipe 103 is fixedly sleeved on the surface of the fixed pipe 104 at the bottom position of the drain hole 105. The enlarged portion can seal the gap between the fixed pipe 104 and the drain pipe 103, so that impurities are discharged through the drain hole 105.

[0031] In one embodiment, the driving component includes a rotating shaft 30 rotatably inserted into the center of the inner shell 102. One end of the rotating shaft 30 passes through the inner shell 102 and the outer shell 101 sequentially and extends to the outside of the outer shell 101. A motor is mounted on the end of the rotating shaft 30 extending to the outer shell 101. The surface of the rotating shaft 30 and a section located inside the inner shell 102 are provided with fan blades 31 arranged in a ring array.

[0032] When the motor starts, it drives the shaft 30 to rotate at high speed. The fan blades 31 rotate synchronously with the shaft 30. The rotating fan blades 31 generate centrifugal force or thrust on the gas entering the inner shell 102 from the air inlet pipe 12, so that the gas gains kinetic and pressure energy. Under the continuous action of the fan blades 31, the gas is pressurized and flows along the inner wall of the inner shell 102, and finally is discharged at high speed from the circumferential air outlet pipe 11, realizing the directional transportation of gas and meeting the needs of gas purification and transportation in coke production.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
