Description

Technical Field

[0001] The present invention relates to the technical field of exhaust gas waste heat utilization, and in particular to an exhaust steam waste heat recovery and utilization system. Background Art

[0002] In the process of petroleum refining, a waste heat boiler system is often configured. In the waste heat boiler system, a thermal deaerator is configured. The thermal deaerator uses steam to heat the normal temperature desalted water (25℃) to the deaerator temperature of 104℃, thereby reducing the oxygen content in the desalted water. The oxygen in the desalted water is discharged from the oxygen outlet of the deaerator. At the same time, a large amount of exhaust steam is discharged into the atmosphere along with the oxygen. The exhaust of exhaust steam wastes a lot of heat energy. These exhaust steam contains a large amount of heat energy, and its heat accounts for about 5% to 10% of the steam used by the deaerator. The enthalpy of exhaust steam and the enthalpy of new steam are theoretically the same; the value of exhaust steam = softening value + heat value.

[0003] At present, the exhaust steam from the deaerator in the waste heat boiler vaporization system of the domestic oil refining catalytic unit is mostly discharged directly into the atmosphere. The emission of exhaust steam from the deaerator causes hot mist in winter and forms "ice hanging" near the equipment frame, and heat waves in summer, which not only cause serious thermal pollution to the production environment, but also may scald on-site workers. There are certain safety hazards, and it is a great waste of energy, and it is impossible to achieve energy conservation and emission reduction. Summary of the invention

The system can also integrate the whole waste steam heat recovery system intelligently to ensure that different components work together to maximize energy utilization efficiency; and establish an efficient data acquisition and processing network to perform comprehensive data management and analysis on the waste steam heat recovery process. The whole system recovers water resources and energy, has significant economic benefits, and can also reduce the emission of greenhouse gas harmful substances, reduce corrosion of deaerator peripheral equipment and buildings, and improve the working environment. The system has advanced technology, strong versatility, energy saving and emission reduction, is suitable for most industrial enterprises, and has broad market application prospects.

[0048] Embodiment 2:

[0049] Based on the first embodiment, this embodiment proposes a specific control process:

[0050] The technical control of the present invention can monitor the liquid level height data in the degassing water storage tank 1 through the detection rod 8 (the liquid level meter range is: 0-1400mm, the output signal is: 4-20mA), and transmit the data signal back to the control component 9, and perform data analysis and control the start and stop and operation of the first water pump 11 and the second water pump 12 through the pre-set program in the control component 9; when the liquid level in the tank is too high, the inlet and outlet water electric valves are interlocked and closed, and when the liquid level in the tank is too low, the pump is interlocked and stopped. The two variable frequency centrifugal pumps (one for use and one for backup) equipped in the degassing water storage tank 1 are the first water pump 11 and the second water pump 12, and the specific control process is as follows:

[0051] Under normal circumstances, the main pump runs and the standby pump stops. The time can be set to reverse the pump regularly and the water pump can be operated at a variable frequency to maintain a stable liquid level in the tank.

[0052] The PID control point is 1000mm. When the liquid level is ≥1050mm, the main pump starts, and when the liquid level is ≤600mm, the main pump stops running.

[0053] When the liquid level is ≥1200mm, start the standby pump and run the dual pumps;

[0054] When the liquid level is ≤900mm, the standby pump stops running;

[0055] When the liquid level is ≤480mm, a low liquid level alarm will sound; when the liquid level is ≤400mm, a low liquid level alarm will sound;

[0056] When the liquid level is ≥1280mm, high level alarm will be triggered;

[0057] When the liquid level is ≥1350mm, a high level alarm will be triggered.

[0058] The control panel interface of the control component 9 can set any one of the two pumps as the main pump or the standby pump. When setting the main pump or the standby pump, it is necessary to exit from the interlocking state and enter the interlocking state after the setting is completed.

[0059] When in automatic operation, high liquid level alarm occurs, and the main pump / backup pump is not started, the electric switch valve of the low-temperature desalted water inlet and outlet pipelines is closed, switched to the original pipeline, and the exhaust gas recovery component 2 exits.
