Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical industry, in particular to a water supply pressure stabilizing tank water replenishing device. Background Art

[0002] The gas environment of the S-Zorb lock hopper device in the petrochemical industry has certain particularities, which are mainly reflected in the high temperature and high pressure of the sample gas with large fluctuation range, high oil content, high particulate matter content, and large fluctuation range of gas pressure.

[0003] An S-Zorb lock hopper device online pretreatment analysis system suitable for this process was specially developed. The water pressure stabilizing unit was found to have some deficiencies after long-term operation. The water level in the pressure stabilizing tank will gradually decrease, resulting in insufficient pressure. The existing water pressure stabilizing unit has the following defects:

[0004] 1) When the gas pressure entering the water pressure regulating tank fluctuates, bubbles of different sizes will be generated in the tank. Larger and more bubbles will cause part of the water to overflow the pressure regulating tank through the overflow port. Since the raw water pressure regulating device cannot replenish water in time, the liquid level will drop.

[0005] 2) When the gas pressure entering the water pressure regulating tank is stable, the water will slowly evaporate due to the long-term gas passing through the water in the tank, causing the liquid level to drop.

[0006] 3) As the liquid level drops, the gas outlet pressure will gradually decrease and the system flow will gradually decrease, which will have a certain impact on the measurement accuracy of the instrument.

[0007] 4) When the liquid level in the tank drops to a certain level, manual water replenishment is required, which brings great inconvenience to system maintenance work.

[0008] In view of this problem, a water supply pressure stabilizing tank water replenishing device is proposed. Utility Model Content

[0035] An overflow port 10 is provided at the upper end of the outer wall of the water pressure stabilizing tank 1. Through the arrangement of the overflow port 10, water can be discharged from the overflow port when the liquid level in the tank is high.

[0036] It should be noted that:

[0037] 1) Water storage tank capacity: no less than 4L, ensuring that the manual water filling cycle exceeds one month;

[0038] 2) The height difference between the balance port and the overflow port is 10mm, ensuring that the liquid level fluctuation does not exceed 10mm;

[0039] 3) Height of balance port from tank bottom: 500mm, to ensure that the pressure generated by the liquid level meets the pressure and flow required by the analyzer.

[0040] By adding an automatic water replenishment device, the liquid level in the water stabilizing tank remains stable, thereby ensuring that the pressure and flow of the gas entering the instrument are more stable, the instrument analysis results are more accurate and stable, and more reliable data is provided for process detection; after the liquid level in the stabilizing tank is stable, a sample gas source with stable pressure is provided to the analyzer, which better protects the analytical instrument and reduces the instrument failure rate; when the automatic water replenishment device is not used, the system needs manual water replenishment every 3-5 days, and after the automatic water replenishment device is used, manual water replenishment can be performed once a month, which greatly reduces the workload of manual maintenance, and can ensure that the liquid level in the stabilizing tank is always stable, and that the pressure and flow of the sample gas are more stable after being processed by the water stabilizing unit, providing more accurate and stable analysis data for production and reducing the amount of manual maintenance.

[0041] The working principle of the utility model is as follows:

[0042] Working principle of water pressure regulating tank:

[0043] 1) There is a certain level of water in the water pressure-stabilizing tank 1. The sample gas enters the tee from the sample gas inlet 12. The two ends of the tee enter the pressure-stabilizing tank and the next-level processing unit respectively. If the sample pressure is higher than the pressure generated by the liquid level in the pressure-stabilizing tank, a part of the gas will be discharged from the bottom of the sample gas pipe 9 and discharged from the overflow port 10 through the pressure-stabilizing tank. Therefore, the pressure of the sample gas at the tee position is equal to the pressure generated by the liquid level in the pressure-stabilizing tank;

[0044] 2) The pressure of the sample gas before and after treatment is relatively stable, with slight fluctuations and higher than the pressure generated by the liquid level in the water pressure-stabilizing tank 1. Therefore, the pressure in the sample gas pipe 9 can be controlled by water level to be equal to the liquid level in the pressure-stabilizing tank, thereby achieving the purpose of stabilizing the pressure of the sample gas through the water pressure-stabilizing tank 1;

[0045] 3) When the sample gas pressure fluctuates greatly, more gas will be discharged from the bottom of the sample gas pipe 9, which will produce larger and more bubbles, and the liquid level in the tank will rise. When the liquid level rises, water will overflow from the overflow port 10. When the airflow becomes smaller, the bubbles decrease and the liquid level drops;

[0046] 4) When the pressure regulating tank works for a long time, the sample gas flows through the water tank, and the water in the tank will evaporate slowly, causing the liquid level to gradually drop.

[0047] Working principle of automatic water filling device:

[0048] 1) Before adding water for the first time, close the automatic water supply maintenance valve 6, close the drain valve at the bottom of the pressure regulating tank, and open the water supply valve 7 at the top of the water storage tank 2;

[0049] 2) Add clean water from the water inlet 8 at the top of the water storage tank 2 until the liquid level gauge 3 reaches the full scale position;

[0050] 3) Close the water filling valve 7 on the top of the water storage tank 2, open the maintenance valve 6, and the water in the water storage tank 2 flows to the water pressure regulating tank 1 through the maintenance valve 6 and the water replenishment port, and the air above the liquid level of the water storage tank 2 is replenished through the balance port;

[0051] 4) When the liquid level in the water stabilizing tank 1 rises to the balance port position, the water level submerges the balance port, and air cannot enter the top of the water tank 2. The air above the liquid level in the water tank 2 cannot be replenished, and the water in the water tank 2 cannot flow into the water stabilizing tank 1, and the liquid level in the water stabilizing tank 1 is maintained at the balance port height;

[0052] 5) When the liquid level in the water pressure regulating tank 1 rises due to excessive sample gas and generates many bubbles, the water will overflow from the overflow port 10;

[0053] 6) When the liquid level of water pressure regulating tank 1 drops below the balance port due to long-term operation or other reasons, the air above the liquid level of water storage tank 2 can be replenished through the balance port, and the water in water storage tank 2 can flow to water pressure regulating tank 1. When the water level of water pressure regulating tank 1 reaches the balance port, water storage tank 2 stops replenishing water to water pressure regulating tank 1;

[0054] 7) Through the above steps, the water level in the pressure-stable tank can be basically maintained within the range of 1CM between the balance port and the overflow port 10. This better ensures the pressure-stabilizing effect of the water pressure-stable tank 1;

[0055] 8) When the water level in the water tank 2 is low during the continuous operation of the system, close the maintenance valve 6 and open the water filling valve 7 to manually add water to the water tank 2. After it is full, close the water filling valve 7 and open the maintenance valve 6 to allow the water tank 2 to continue to automatically replenish water.

[0056] The above shows and describes the basic principle, main features and advantages of the utility model.
