Abstract
Description
Technical Field
[0001] This utility model relates to a device for stabilizing the bottom water level of a thin oil-sealed gas holder, used to maintain a stable bottom water level in the gas holder, and belongs to the technical field of metallurgical gas pipeline equipment. Background Technology
[0002] Metallurgical enterprises produce by-product gases such as blast furnace gas, coke oven gas, converter gas, and producer gas, which play a crucial role in the energy structure of these enterprises. Condensate in the gas reaches saturation at a certain temperature. When the gas temperature decreases, the previously saturated condensate precipitates out, reaching saturation at the new temperature. During gas flow, some condensate is discharged through the condensate drain due to gravity, but approximately 50-70% of the condensate, due to its small particle size, remains entrained in the gas and floats in the gas, eventually entering the gas holder. If this condensate is not removed, it will cause water accumulation in the oil drain at the bottom of the holder. If drainage is not timely, the oil-water separator will fail to separate any oil, or the separated oil will contain excessive water, damaging the oil pump. In severe cases, this can lead to pump shutdown, causing the piston oil level to drop too low and potentially resulting in a major accident. Therefore, maintaining a stable water level at the bottom of the gas holder is extremely important. The common practice at home and abroad is to add an oil level detection device at the bottom of the cabinet and manually drain the water periodically through the bottom drain valve. During drainage, the water level at the bottom of the cabinet must be closely monitored. At the same time, there is a lag between the drainage process and the oil level display, and there is a possibility that the sealing oil at the bottom of the cabinet may be discharged during drainage. This method increases manpower and wastes human resources, resulting in increased personnel costs. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a device for stabilizing the water level at the bottom of a thin oil-sealed gas holder. This device is installed next to the bottom of the gas holder and connected to the bottom of the holder. It has the functions of dehydration, water replenishment, stabilizing the water level at the bottom of the holder and preventing gas leakage. It can effectively ensure the balance of the water level at the bottom of the holder and ensure the safe and stable operation of the equipment.
[0004] The technical solution to the above technical problem is:
[0005] A water level stabilization device for the bottom of a thin oil sealed gas holder includes a water level regulating cylinder, a connecting pipe, a partition, a water inlet pipe, a water level regulating rod, a water inlet rubber valve, a float, and a support rod. The water level regulating cylinder is an upright cylindrical body fixed to the outside of the gas holder. The lower part of the water level regulating cylinder is connected to the bottom of the gas holder through the connecting pipe. The partition is vertically fixed inside the water level regulating cylinder, dividing it into a water storage chamber and an overflow chamber. The water storage chamber contains a water inlet pipe, with the lower inlet of the water inlet pipe located at the bottom of the water level regulating cylinder. On the side wall of the overflow chamber, the upper end of the inlet pipe is located at the upper part of the water level regulating cylinder. There is a drain outlet on the side wall of the water level regulating cylinder at the lower part of the overflow chamber. The water level regulating rod is a horizontal rod located at the upper part of the water storage chamber. One end of the water level regulating rod is fixedly connected to the inlet rubber valve, which is opposite to the upper outlet of the inlet pipe. The other end of the water level regulating rod is welded with a float ball, which is located on the water surface in the water storage chamber. The middle part of the water level regulating rod is connected to the upper end of the vertical support rod through a rotating shaft. The lower end of the support rod is fixedly connected to one side of the inlet pipe.
[0006] The aforementioned thin oil sealed gas holder bottom water level stabilization device has a connecting pipe valve installed on the connecting pipe.
[0007] In the above-mentioned thin oil sealed gas holder bottom water level stabilization device, the two sides and bottom end of the partition are connected to the inner wall and bottom surface of the water level regulating cylinder, the upper end of the partition has a gap with the top surface of the water level regulating cylinder, and the volume of the water storage chamber on both sides of the partition is larger than the volume of the overflow chamber.
[0008] The above-mentioned thin oil sealed gas holder bottom water level stabilization device has a U-shaped bracket at the upper end of the support rod. The two side plates of the U-shaped bracket have opposite shaft holes. The water level adjusting rod is placed between the two side plates of the U-shaped bracket. The water level adjusting rod has a shaft hole that is opposite to the shaft holes of the two side plates of the U-shaped bracket. The rotating shaft passes through the shaft hole to rotatably connect the water level adjusting rod and the U-shaped bracket.
[0009] The aforementioned thin oil sealed gas holder bottom water level stabilization device has a 90-degree bend at the lower end of the water inlet pipe on one side of the water level regulating cylinder. The lower end of the water inlet pipe is vertically and fixedly connected to the side wall of the water level regulating cylinder. The lower end of the water inlet pipe is connected to the water supply pipe, which is equipped with a water supply valve. The drain outlet on one side of the water level regulating cylinder is connected to the overflow pipe, which is connected to the circulating water tank.
[0010] The beneficial effects of this utility model are:
[0011] The water level regulating cylinder of this utility model is connected to the bottom of the gas holder through a connecting pipe. The condensate in the gas holder can enter the water level regulating cylinder through the connecting pipe. When the water level in the water level regulating cylinder exceeds the partition, it will be discharged from the drain outlet of the overflow chamber. The water inlet pipe can replenish water into the water level regulating cylinder. When the water level in the water level regulating cylinder is lower than the outlet at the upper end of the water inlet pipe, the float descends and automatically opens the water inlet rubber valve of the water level regulating rod to replenish water. When the water level is higher than the outlet of the water inlet, the float rises and automatically closes the water inlet rubber valve of the water level regulating rod to stop replenishing water, thus maintaining a stable water level in the cylinder.
[0012] This utility model has a simple structure and is easy to install. It can directly utilize the drain pipe in front of the oil-water separator in the oil pump room to achieve automatic water replenishment, replacing the original manual drainage, effectively balancing the water level at the bottom of the gas holder, preventing gas leakage, and thus ensuring the stable operation of the gas storage system. The equipment has no additional energy requirements, saves energy, reduces human resource costs, and has significant economic benefits. Attached Figure Description

[0018] Figure 1 , 2 The water level regulating cylinder 2 is an upright cylindrical body. The water level regulating cylinder 2 is fixed to the outside of the gas holder 1. The lower part of the water level regulating cylinder 2 is connected to the bottom of the gas holder 1 through the connecting pipe 3. A connecting pipe valve 4 is installed on the connecting pipe 3. The condensate in the gas holder 1 can enter the water level regulating cylinder 2 through the connecting pipe 3.
[0019] Figure 1 , 2As shown, the baffle 5 is vertically fixed inside the water level regulating cylinder 2. The sides and bottom of the baffle 5 are connected to the inner wall and bottom surface of the water level regulating cylinder 2, and there is a gap between the upper end of the baffle 5 and the top surface of the water level regulating cylinder 2. The baffle 5 divides the water level regulating cylinder 5 into a water storage chamber 6 and an overflow chamber 7. The volume of the water storage chamber 6 on both sides of the baffle is larger than the volume of the overflow chamber 7.
[0020] Figure 1 , 2 The display shows that there is a water inlet pipe 8 in the water storage chamber 6. The lower end of the water inlet pipe 8 is located on the lower side wall of the water level regulating cylinder 2, and the upper end of the water inlet pipe 8 is located on the upper part of the water level regulating cylinder 2. The water inlet pipe 8 is connected to the water replenishment pipe, and a water replenishment valve is installed on the water replenishment pipe. The water inlet pipe 8 can replenish water into the water level regulating cylinder.
[0021] Figure 1 , 2 The display shows that a water level regulating rod 9 is located at the top of the water storage chamber 6. The water level regulating rod 9 is a horizontal rod, with one end fixedly connected to an inlet rubber valve 10, which is opposite to the upper outlet of the inlet pipe 8. A float ball 11 is welded to the other end of the water level regulating rod 9, and the float ball 11 is positioned on the water surface in the water storage chamber 6. The middle part of the water level regulating rod 9 is connected to the upper end of a vertical support rod 12 via a rotating shaft 13, and the lower end of the support rod 12 is fixedly connected to one side of the inlet pipe 8. The support rod 12 and the rotating shaft 13 act as a fulcrum, allowing the water level regulating rod 9 to rotate around the rotating shaft 13, thereby enabling the float ball 11 to control the inlet rubber valve 10 to open and close the inlet pipe 8, thus replenishing water.
[0022] Figure 3 The display shows that the upper end of the support rod 12 has a U-shaped bracket 15, and there are corresponding shaft holes on the two side plates of the U-shaped bracket 15. The water level adjusting rod 9 is placed between the two side plates of the U-shaped bracket 15. The water level adjusting rod 9 has a shaft hole that is opposite to the shaft holes on the two side plates of the U-shaped bracket 15. The rotating shaft 13 passes through the shaft hole to rotatably connect the water level adjusting rod 9 and the U-shaped bracket 15. The water level adjusting rod 9 can rotate around the rotating shaft 13.
[0023] Figure 1 , 2 The overflow chamber 7 has a drain outlet 14 on the side wall of the water level regulating cylinder at the bottom. The drain outlet 14 is connected to an overflow pipe, which is connected to the circulating water tank. The condensate in the overflow chamber 7 can be discharged from the drain outlet 14 to maintain the water level in the water level regulating cylinder 2.
[0024] The working process of this utility model is as follows:
[0025] The water level regulating cylinder 2 of this utility model is connected to the bottom of the gas holder 1 through the connecting pipe 3, and the condensate in the gas holder 1 enters the water level regulating cylinder 2 through the connecting pipe 3.
[0026] When the water level in the water level regulating cylinder 2 exceeds the partition 5, the water passes over the partition 5 and enters the overflow chamber 7, and then is discharged from the drain outlet 14 of the overflow chamber 7, keeping the water level in the water level regulating cylinder 2 unchanged, while maintaining the height of the condensate at the bottom of the gas holder 1.
[0027] When the water level in the water level regulating cylinder 2 is lower than the outlet at the upper end of the inlet pipe 8, the float ball 11 descends, the water level regulating rod 9 rotates around the rotating shaft 13 at the upper end of the support rod 12, the inlet rubber valve 10 connected to the other end of the water level regulating rod 9 is lifted, and the inlet pipe 8 replenishes water to the water level regulating cylinder 2.
[0028] As the water level in the water level regulating cylinder 2 rises, the float ball 11 rises accordingly, causing the water level regulating rod 9 to rotate around the rotating shaft 13 at the upper end of the support rod 12. When the water level reaches a point higher than the outlet of the inlet pipe 8, the inlet rubber valve 10 at the other end of the water level regulating rod 9 descends to close the inlet of the inlet pipe 8, and the inlet pipe 8 stops replenishing water, thus maintaining a stable water level in the water level regulating cylinder 2.
