Description

Technical Field

[0001] The present application relates to the technical field of waste liquid treatment, and in particular to a temperature regulating structure and a waste liquid incineration boiler. Background Art

[0002] Waste liquid is usually treated by incineration. Toxic waste liquid is burned in an incinerator, and the waste liquid is decomposed into non-toxic gas during the combustion process and discharged into the atmosphere. Incineration is a comprehensive process of high-temperature decomposition and deep oxidation. Through incineration, the toxic and harmful organic components in the waste liquid can be completely oxidized and decomposed into H2O and CO2 and discharged, so as to reduce the volume of waste, eliminate toxic and harmful substances to the maximum extent, recover available energy and protect the environment.

[0003] At present, a Chinese patent with publication number CN114234210A discloses an integrated incineration boiler for petrochemical waste liquid, which includes: an insulated furnace, a matrix burner group, a radiation cooling chamber, a superheater, a quenching tower, a tail flue, and an economizer feed water heating system. The flue gas inlet of the insulated furnace is connected to the matrix burner group, the flue gas outlet of the insulated furnace is connected to the flue gas inlet of the radiation cooling chamber, a superheater is provided at the flue gas outlet of the radiation cooling chamber, the flue gas outlet of the radiation cooling chamber is connected to the flue gas inlet of the quenching tower, the flue gas outlet of the quenching tower is connected to the flue gas inlet of the tail flue, and a first economizer and a second economizer are sequentially provided in the tail flue from the smoke inlet to the smoke outlet; the first economizer and the second economizer are connected to the economizer feed water heating system.

[0004] The main purpose of the quench tower is to keep the flue gas away from the temperature range of dioxin regeneration. Effective temperature control of the flue gas inlet temperature of the quench tower can effectively reduce the regeneration of dioxins. If the flue gas temperature in front of the quench tower is too high, the amount of water sprayed in the quench tower will increase, and the ash in the flue gas will be compacted in the quench tower, which may cause collapse; while if the flue gas temperature is too low, a large amount of dioxins will be generated.

[0005] Therefore, when the temperature of the flue gas flowing out of the flue gas outlet of the radiation cooling chamber is too high or too low, the quenching tower will not work well, thereby affecting the overall treatment of the waste liquid. Summary of the invention

When the adjusting rod 56 moves, the adjusting rod 56 drives the second fixing block 746 to move in the direction close to the fifth rotating shaft 742, and the second fixing block 746 drives the second locking block 747 to move; when the fourth rack 741 is close to the adjusting ring block 55, the two adjacent teeth are still meshed with the sixth gear 743, and the second locking block 747 is squeezed by the fifth rotating shaft 742, and the second spring 748 is compressed; when the fourth rack 741 is close to the adjusting ring block 55, a tooth thereof contacts the sixth gear 743, the second locking block 747 is aligned with the second locking groove on the fifth rotating shaft 742, and the second spring 748 restores its elasticity The deformation force will drive the second locking block 747 to move, so that the second locking block 747 is engaged with the second locking groove, and at this time, the two limiting blocks 72 are both pressed against the adjusting shaft 32, and the driving block 341 has not yet been completely separated from the driving groove 511 on the first adjusting block 51; when the subsequent adjusting rod 56 continues to move, the fourth rack 741 is no longer engaged with the sixth gear 743, and the two limiting blocks 72 are both pressed against the adjusting shaft 32, and the second locking block 747 enters the second locking groove of the fifth rotating shaft 742, that is, when the fourth rack 741 is not engaged with the sixth gear 743, the adjusting rod 56 will continue to move.

[0054] The implementation principle of one embodiment of the present application is: when the smoke temperature in the second adjustment chamber 112 is still relatively high, for example, when the smoke temperature is higher than 560 degrees, start the fan and the second motor 342, the output shaft of the second motor 342 drives the driving block 341 to rotate, the driving block 341 drives the first adjustment block 51 to rotate, the first adjustment block 51 drives the second adjustment block 52 to rotate, the second adjustment block 52 drives the adjustment shaft 32 to rotate, the adjustment shaft 32 drives the sealing plate 33 to rotate, so that the sealing plate 33 no longer blocks the passage of the air supply pipe 31; the fan blows air into the air supply pipe 31, and the air enters the second adjustment chamber 112, thereby cooling the smoke in the second adjustment chamber 112.

[0055] When the temperature of the flue gas in the third adjustment chamber 113 is relatively low, for example, when the flue gas temperature is lower than 510 degrees, the first motor 234 is started to make the moving block 21 drive the infrared radiation heater 24 to move. When the moving block 21 moves, the baffle 22 no longer blocks the first cavity 114, and then the infrared radiation heater 24 heats the flue gas in the third adjustment chamber 113.

[0056] In this way, the temperature of the flue gas entering the quench tower 84 is precisely controlled within the range of 520°C ± 10°C, ensuring efficient operation of the quench tower 84 and effectively controlling the generation of dioxins.

[0057] When the flue gas in the third adjustment chamber 113 is heated, the sealing plate 33 is required to block the passage of the air supply pipe 31; therefore, when the moving block 21 moves, the first connecting block 431 will drive the switching block 41 to move, and the switching block 41 will drive the second motor 342 and the first locking block 42 to move, so that the driving block 341 on the second motor 342 moves in a direction away from the first adjustment block 51, and the first locking block 42 moves in a direction close to the first locking groove.

[0058] When the moving block 21 moves, the moving block 21 will also drive the second supporting block 610 to move toward the direction close to the third adjustment chamber 113, and the sixth connecting block 627 will quickly pull the fourth adjusting block 54 to move, and the fourth adjusting block 54 will drive the adjusting rod 56 to move, and the adjusting rod 56 will drive the adjusting ring block 55 to move, and the third adjusting block 53 on the adjusting ring block 55 will drive the second adjusting block 52 to move, and the second adjusting block 52 will drive the first adjusting block 51 to move.

[0059] In this way, the first adjusting block 51 and the driving block 341 will move in opposite directions, so that the driving groove 511 on the first adjusting block 51 and the driving block 341 on the second motor 342 will be quickly separated; and before the driving block 341 is separated from the driving groove 511 of the first adjusting block 51, the two limiting blocks 72 have been pressed against the adjusting shaft 32, so that when the driving block 341 is separated from the driving groove 511, the adjusting shaft 32 will not rotate, that is, when the two limiting blocks 72 are pressed against the adjusting shaft 32, and the end of the second locking block 747 away from the second fixed block 746 enters the second locking groove on the fifth rotating shaft 742, the driving block 341 is still not completely separated from the driving groove 511.

[0060] When the two limiting blocks 72 are pressed against the adjusting shaft 32, a portion of the first locking block 42 enters into the first locking groove, that is, when the fourth rack 741 is not engaged with the sixth gear 743, a portion of the first locking block 42 enters into the first locking groove.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
