Referring to fig. 2 and 3, the coke oven gas transmission system 00 includes: the device comprises a gas pipe 1, a spraying device 2, a scraping plate device 3, a collecting box 4 and a baffle plate 5.
The gas pipe 1 is used for communicating the coke oven 01 and the purifying device 02, and the gas pipe 1 is provided with an oil slag outlet; the spraying device 2 is arranged in the air inlet end of the air conveying pipe 1 and is used for spraying liquid to raw gas entering the air conveying pipe 1; the scraping plate device 3 is arranged in the gas pipe 1 and is used for scraping tar residues deposited in the gas pipe 1; and the baffle plate 5 is arranged on the gas pipe 1 and used for shielding gas at the upper part of the gas pipe 1 and reserving a gap for scraping tar residues.
Preferably, the coke oven gas transmission system 00 further comprises a collecting box 4, which is arranged at the oil residue outlet of the gas transmission pipe 1 and is used for collecting the tar residue.
In practical application, raw gas generated by the coke oven 01 passes through the coke oven gas transmission system 00 and then enters the purification device 02 for purification. In the process, the spraying device 2 arranged at the air inlet end of the air conveying pipe 1 sprays liquid on the raw coke oven gas entering the air conveying pipe 1, the sprayed liquid reduces the temperature of the raw coke oven gas, and then most of dust and other impurities entering the air conveying pipe 1 along with the raw coke oven gas are condensed and washed, for example, the raw coke oven gas is continuously sprayed by using circulating ammonia water, and the temperature of the raw coke oven gas is reduced from 650 degrees to 82 degrees after the circulating ammonia water is sprayed. Then, the washed dust and other impurities enter the gas pipe 1 and settle to form tar slag. The scraper means 3 then scrapes the deposited tar residue into a collecting tank 4.
In order to ensure that raw gas does not leak from the oil and slag outlet of the gas pipe 1, a baffle plate 5 is arranged at the oil and slag outlet of the gas pipe 1, and a gap for the outflow of tar slag is reserved between the baffle plate 5 and the gas pipe 1 so that the tar slag can flow out from the oil and slag outlet. For example, to ensure that the baffle 5 is effective against the raw gas, the baffle 5 may be inserted at least 40mm into the liquid in the gas delivery pipe 1, but the baffle 5 is not connected to the bottom of the gas delivery pipe 1.
By the scheme provided by the embodiment of the invention, dust in raw coke oven gas generated by the coke oven 01 can be removed in the process of passing through the coke oven gas transmission system 00, so that the dust is prevented from entering the purification device 02 along with the raw coke oven gas, the pipeline in the purification device 02 is prevented from being blocked, and the normal production of the subsequent purification device 02 can be ensured.
Specifically, please continue to combine fig. 2 and 3, in practical application, the gas pipe 1 includes: a vertically arranged riser 13, a horizontally arranged header 11, and a bridge pipe 12 communicating the riser 13 and the header 11.
Wherein, the ascending pipe 13 is used for communicating with the coke oven 01, and the gas collecting pipe 11 is used for communicating with the purifying device 02;
specifically, the spraying device 2 is mounted on the bridge pipe 12, and is used for spraying liquid to raw gas passing through the bridge pipe 12. The scraper device 3 is arranged in the gas collecting tube 11 and is used for scraping tar residues deposited in the gas collecting tube 11. The gas collecting tube 11 is provided with an oil residue outlet, and the collecting box 4 is arranged at the oil residue outlet of the gas collecting tube 11 and is used for collecting tar residue in the gas collecting tube 11. The baffle 5 is arranged on the gas collecting tube 11 and is used for shielding a notch reserved for the outflow of tar residues at the oil residue outlet of the gas collecting tube 11.
In practical application, raw gas generated by the coke oven 01 sequentially passes through the riser 13, the bridge pipe 12 and the gas collecting pipe 11, and enters the purifying device 02 for purification. After the raw gas passing through the bridge pipe 12 is sprayed with liquid by the spraying device 2, impurities such as dust entering the ascending pipe 13 along with the raw gas are condensed and washed. The washed dust and other impurities enter the gas collecting pipe 11 and settle to form tar slag. The scraper means 3 then scrapes the deposited tar residue into a collecting tank 4.
The baffle plate 5 arranged in the gas collecting tube 11 is inserted into the liquid in the gas collecting tube 11, and a gap for the outflow of tar residue is reserved so as to ensure that raw gas does not leak from the oil residue outlet of the gas collecting tube 11, and the tar residue can flow out from the oil residue outlet.
It will be appreciated that during installation of the spraying device 2, the spraying direction of the spraying device 2 may be the same as the flow direction of the raw gas, i.e. the spraying device 2 is installed along the raw gas flow. The spraying direction of the spraying device 2 can be opposite to or perpendicular to the flow direction of the raw gas, namely, the spraying device 2 is installed against the raw gas flow or is installed perpendicular to the raw gas flow.
Specifically, in order to improve the washing and condensing effects of the spraying device 2 on dust in raw gas, there may be a plurality of spraying devices 2 on the bridge pipe 12.
Preferably, an air inlet and an air outlet are formed in the side wall of the air collecting pipe 11, the air collecting pipe 11 is communicated with the bridge pipe 12 through the air inlet, and is communicated with the purifying device 02 through the air outlet.
Referring to fig. 2, in one implementation, two ports of the gas collecting tube 11 are oil residue outlets, and each port is inclined upward from the center line of the gas collecting tube 11.
In order to reduce the size of the cross section of the port of the gas collecting tube 11 and prevent raw gas in the gas collecting tube 11 from leaking from the port, the two ports of the gas collecting tube 11 can have a certain gradient and tilt, that is, the two ports of the gas collecting tube 11 are inclined upwards relative to the central line of the gas collecting tube 11. In practical applications, the inclination angle of the port of the gas collecting tube 11 may be determined according to practical experience or practical working conditions, for example, the upward inclination angle of the port of the gas collecting tube 11 may be 45 ° or 30 °.
Specifically, the coke oven gas delivery system 00 provided in this embodiment includes a plurality of ascending pipes 13 and bridge pipes 12 corresponding to the ascending pipes, where each ascending pipe 13 is communicated with the gas collecting pipe 11 through the corresponding bridge pipe 12.
In practical use, raw gas generated in the coke oven 01 flows into the gas collecting pipe 11 through the plurality of rising pipes 13 and the bridge pipe 12 corresponding to each rising pipe 13. The spraying devices 2 are arranged on the bridge pipes 12, and after the raw gas passing through the bridge pipes 12 is sprayed with liquid by the spraying devices 2 arranged on the bridge pipes 12, impurities such as dust entering the bridge pipes 12 along with the raw gas are condensed and washed. The dust and other impurities washed in each bridge pipe 12 enter the gas collecting pipe 11 and settle to form tar residues. The scraper means 3 then scrapes the deposited tar residue into a collecting tank 4.
It will be appreciated that in order to enhance the scrubbing and condensing effect of the spraying device 2 on dust in raw gas, 1 or more spraying devices 2 may be provided on each bridge pipe 12.
In practical application, the raw gas sprayed by the spraying device 2 can generate an oil-water mixture. For example, it is assumed that the spraying device 2 sprays with circulating ammonia water, and the sprayed raw gas produces a tar-ammonia water mixture.
In order to timely discharge the oil-water mixture in the gas collecting tube 11 so as to avoid excessive oil-water mixture and influence on normal operation of the gas collecting tube 11, a liquid outlet 6 is formed in the side wall of the gas collecting tube 11, and the oil-water mixture generated in the gas collecting tube 11 is timely discharged.
Through the liquid outlet 6, the oil-water mixture in the gas collecting tube 11 can be discharged in time, but the raw gas in the gas collecting tube 11 can also leak from the liquid outlet 6. In order to avoid the raw gas in the gas collecting tube 11 leaking from the liquid outlet 6, the coke oven gas transmission system 00 further comprises: a gravity flow pipeline 7 and a water seal tank 8.
One end of the self-flow pipeline 7 is communicated with the liquid outlet 6, and the other end of the self-flow pipeline is inserted into the liquid in the water seal groove 8. Through the liquid outlet 6 and the self-flowing pipeline 7, the oil-water mixture generated in the gas collecting pipe 11 is discharged to the bottom of the water seal tank 8, and a certain water seal height is arranged in the water seal tank 8, so that the gas in the gas collecting pipe 11 can not enter the water seal tank 8. It should be noted that, because the space of the water seal tank 8 is limited, the water seal tank 8 can also discharge the oil-water mixture at the bottom. For example, assuming that a tar-ammonia water mixture is generated in the gas header 11, the water seal tank 8 may continuously discharge the tar-ammonia water mixture to the tar-ammonia water separation device.
Alternatively, the coke oven 01 gas delivery system 00 can include a plurality of liquid discharge ports 6. The number of the self-flow pipelines 7 and the water seal tanks 8 is the same as that of the liquid discharge ports 6. And the liquid discharge ports 6, the self-flowing pipeline 7 and the water seal tank 8 are in one-to-one correspondence. Each drain port 6 is communicated with a water seal tank 8 corresponding to the self-flow pipeline 7 through the self-flow pipeline 7 corresponding to the drain port.
The oil-water mixture in the gas collecting pipe 11 is discharged to each water seal tank 8 through each liquid outlet 6 and the gravity flow pipe 7.
Specifically, in order to improve the service life and load capacity of the scraper device 3, the scraper device 3 in this embodiment is specifically a chain type scraper device 3, and the chain type scraper device 3 is mounted at the bottom in the gas collecting pipe 11.
The chain scraper device 3 comprises a scraper part and a chain wheel, wherein the scraper part is a scraper group which is arranged continuously. The chain scraper device 3 is connected with a motor through a speed reducer. The motor drives the chain wheel to rotate through driving the speed reducer, and when the chain wheel rotates, the scraping plate group is driven to continuously and circularly operate.
Of course, the squeegee device 3 may be another type of squeegee device, and is not limited thereto.
In order to further remove dust entering the gas pipe 1 along with raw gas, the coke oven 01 gas transmission system 00 further comprises a washing spray pipe 9, wherein the washing spray pipe 9 is arranged in the gas outlet end of the gas pipe 1 and is used for spraying liquid to the raw gas flowing out of the gas pipe 1.
It will be appreciated that during the installation of the wash lance 9, the direction of the spray of the wash lance 9 may be the same as the direction of flow of the raw gas, i.e. the wash lance 9 is installed in the flow of the raw gas. The spraying direction of the washing spray pipe 9 can be opposite to or perpendicular to the flow direction of the raw gas, namely, the washing spray pipe 9 is installed against the raw gas flow or is installed perpendicular to the raw gas flow.
