Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of wire laying device, specifically relating to a dry quenching coke water seal device. Background Technology
[0002] Dry quenching is a coke quenching process that uses inert gas to cool red-hot coke. The water seal in dry quenching is primarily used to seal the passage between the dry quenching furnace and the waste heat boiler, preventing gas leakage. The water seal utilizes the hydrostatic pressure of a certain height to resist pressure changes inside the drain pipe. When gas encounters the water seal device, it is pressured by the water, thus sealing the gap between the dry quenching furnace and the waste heat boiler, preventing gas leakage and ensuring production safety. The water seal device can recover heat from the coke oven gas, improving energy utilization. Furthermore, it also plays a role in dust removal, reducing environmental pollution.
[0003] In existing technologies, water seal devices mostly use a sealed structure, which makes it impossible to thoroughly clean the inside. After long-term use, impurities may accumulate inside, affecting the sealing effect. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dry quenching coke water seal device.
[0005] To achieve the above objectives, this utility model provides a dry quenching coke water seal device, including a lower cavity, an upper cavity at the upper end of the lower cavity, a drain outlet on one side of the lower cavity, a positive pressure exhaust outlet at the upper end of the other side of the lower cavity, a water inlet on one side of the upper cavity, a negative pressure air inlet at the upper end of the other side of the upper cavity, a sealing cover at the upper end of the upper cavity, an air inlet and an exhaust outlet at the upper end of the sealing cover, and a sealing locking mechanism between the upper cavity and the lower cavity.

[0021] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] like Figures 1-6 The dry quenching coke water seal device shown includes a lower cavity 1, an upper cavity 2 at the upper end of the lower cavity 1, a drain outlet 7 on one side of the lower cavity 1, a positive pressure exhaust outlet 8 at the upper end of the other side of the lower cavity 1, a water inlet 6 on one side of the upper cavity 2, a negative pressure air inlet 5 at the upper end of the other side of the upper cavity 2, a sealing cover 3 at the upper end of the upper cavity 2, an air inlet and exhaust outlet 4 at the upper end of the sealing cover 3, and a sealing locking mechanism between the upper cavity 2 and the lower cavity 1.
[0023] like Figure 3 As shown, the lower cavity 1 has a protruding ring 14 at the upper end, and a water collection trough 12 is provided at the center of the lower surface of the inner wall of the lower cavity 1. A water seal pipe 11 is fixedly installed at the bottom of the upper cavity 2. The water seal pipe 11 passes through the lower cavity 1 and the lower end of the water seal pipe 11 extends into the water collection trough 12. Water flows into the water collection trough 12 to form a water seal.
[0024] The water inlet 6 penetrates the lower end of the inner part of the upper cavity 2 and is flush with the upper end of the water seal pipe 11. The negative pressure air inlet 5 penetrates the lower end of the inner part of the upper cavity 2 and extends to the upper end of the water seal pipe 11. When gas flows into the upper cavity 2 through the negative pressure air inlet 5, the water inlet 6 continuously drains water, and the gas breaks through the water seal and flows to the air inlet and outlet 4.
[0025] The upper cavity 2 and the lower cavity 1 are connected by a water seal pipe 11, and the lower end of the water seal pipe 11 extends to the inside of the water collection tank 12.
[0026] like Figure 4 , Figure 6 As shown, the sealing and locking mechanism includes a slot 17 on the outer side of the lower end of the upper cavity 2. A sealing ring 9 is sleeved on the outer side of the connection between the upper cavity 2 and the lower cavity 1. A sealing protrusion 15 is provided on the inner surface of the sealing ring 9. The sealing protrusion 15 cooperates with the protruding ring 14 to form a seal, which facilitates the quick disassembly of the upper cavity 2 and the lower cavity 1 by the staff.
[0027] Two fixing screws 16 arranged vertically are provided at both ends of the outer surface of the sealing ring 9. A connecting block 10 is provided at the connection of the two sealing rings 9. The fixing screws 16 pass through the connecting block 10, and the fixing screws 16 are located outside the connecting block 10 and are rotatably installed with limit nuts 13. The two sealing rings 9 are fixed in position by the connecting block 10, and the position is fixed between the upper cavity 2 and the lower cavity 1 by fitting the groove 17.
[0028] Working principle: Before use, the operator enters the upper cavity 2 through the inlet 6. After the liquid level exceeds the upper end of the water seal pipe 11, it flows to the water collection tank 12. The water level in the water collection tank 12 rises to achieve a water seal between the upper cavity 2 and the lower cavity 1.
[0029] When the tank pressure is higher than atmospheric pressure, the water inside the upper cavity 2 is forced into the negative pressure air inlet 5. At this time, the water inlet 6 stops releasing water, and the gas enters, creating a water seal of a certain height inside the negative pressure air inlet 5. The gas cannot be discharged from the negative pressure air inlet 5 at this time, achieving a one-way seal. The gas enters the interior of the upper cavity 2 through the air inlet 4, and forces the water out of the upper cavity 2 through the water seal pipe 11. The overflowing water is discharged through the drain outlet 7, while the gas is discharged through the positive pressure exhaust outlet 8. The water seal height of the lower cavity 1 is the water seal pressure.
[0030] When the pressure is lower than atmospheric pressure, gas enters the inner side of the upper cavity 2 through the negative pressure inlet 5. The gas breaks through the water seal and flows to the inlet and outlet 4, entering the target tank. The pressure inside the upper cavity 2 is lower than atmospheric pressure, but the water inlet 6 continuously drains water. The gas entering raises the liquid level, which prevents air from entering the lower cavity 1.
[0031] If not cleaned promptly after prolonged use, a large amount of impurities will accumulate inside the device, and components may rust and corrode, affecting their service life and even causing blockages that affect the overall operation of the equipment. Because gas passes through water, various impurities, dirt, and scale will accumulate, leading to a decrease in sealing effectiveness and causing gas leaks over time. Workers remove the limiting nuts 13 that are rotatably installed at both ends of the sealing ring 9, disassemble the connecting block 10, and then remove the sealing ring 9. The inner side of the sealing ring 9 has a protruding ring 14 corresponding to the groove 17 at the lower end of the upper cavity 2. After removing the sealing cover 3, the inside of the upper cavity 2 can be cleaned; after removing the upper cavity 2, the inside of the lower cavity 1 can be cleaned.
[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
