Description

[0003] The flash tank is prone to vibration during operation, which is mainly caused by the flash valve on the flash tank. The flash valve is an automatic control valve used to control the pressure and flow of fluid. When high temperature and high pressure fluid passes through the flash valve, the fluid flows from a high pressure area to a low pressure area, and its pressure decreases rapidly. At this time, part of the fluid will rapidly change from liquid to gas, causing flash phenomenon. When the phase state and pressure of the fluid in the flash valve change dramatically, it is easy to cause vibration of the flash valve, and then drive the flash tank to vibrate.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0027] In order to solve the technical problem that long-time violent shaking of the flash tank can cause loosening of the flash tank pipeline fixing structure, thereby causing certain safety hazards, the present application provides a flash tank stabilizing system, which can reduce the vibration of the flash tank during operation, thereby preventing loosening of the flash tank pipeline fixing structure and improving safety.

[0028] Please refer to Fig. 1, which is a structural schematic diagram of a flash tank stabilizing system according to an embodiment of the present application. The flash tank stabilizing system comprises a support mechanism 1 and a damping assembly 2.

[0029] The support mechanism 1 comprises a base 11, a column 12 and a top plate 13. The base 11 is used to fix the flash tank 3. The column 12 is used to connect the base 11 and the top plate 13.

[0030] The damping assembly 2 comprises a hydraulic cylinder 21, a pressing plate 22, a strain gauge 23 and an oil pump 24. The cylinder body of the hydraulic cylinder 21 is fixed to the top plate 13. The output shaft of the hydraulic cylinder 21 is fixedly connected to one end of the pressing plate 22. The other end of the pressing plate 22 is connected to one end of the strain gauge 23. The other end of the strain gauge 23 is connected to the upper end of the flash tank 3. The oil pump 24 is used to supply oil to the hydraulic cylinder 21. According to the pressure detected by the strain gauge 23, the output pressure of the oil pump 24 can be adjusted, so that the pressure of the flash tank 3 on the pressing plate 22 is equal to the pressure of the hydraulic cylinder 21 on the pressing plate 22.

[0031] The vibration of the flash tank 3 in operation is mainly in the up-down direction. When the flash tank 3 vibrates upward, the pressure on the strain gauge 23 increases, and the oil pump 24 increases the output pressure, so that the pressure of the flash tank 3 on the pressing plate 22 is equal to the pressure of the hydraulic cylinder 21 on the pressing plate 22. Therefore, the pressure increased by the oil pump 24 can limit the upward vibration of the flash tank 3, reduce the vibration of the flash tank 3 in operation, thereby preventing the loosening of the pipe fixing structure of the flash tank 3 and improving the safety.

[0032] It should be understood that the oil pump 24 is a hydraulic pump, which is a hydraulic system power element that converts mechanical energy into hydraulic energy by driving an engine or motor. It sucks oil from the oil tank, forms pressure oil and discharges it, and finally sends it to the actuator (such as hydraulic cylinder, hydraulic motor, etc.). The working of the hydraulic pump is based on the change of pump cavity volume. When the pump cavity volume decreases, the oil is compressed and pressure is generated; when the pump cavity volume increases, a vacuum is formed, and oil is sucked from the oil tank. This periodic change in volume allows the hydraulic pump to continuously suck and discharge oil, providing stable pressure oil for the hydraulic system. In this embodiment, the inlet of the oil pump 24 is communicated with the oil tank (not shown), and the oil tank contains hydraulic oil.

[0036] In one of the embodiments, referring to FIG. 1 and FIG. 3, the damping assembly 2 further comprises two upper inclined rods 25, the lower ends of the two upper inclined rods 25 are fixed to the two sides of the upper end of the flash tank 3 respectively, the two upper inclined rods 25 are inclined and oppositely arranged; the number of the hydraulic cylinders 21, the pressing plates 22, the strain gauges 23 and the oil pumps 24 is two, the cylinder bodies of the two hydraulic cylinders 21 are fixed to the top plate 13, the output shafts of the two hydraulic cylinders 21 are fixedly connected with one ends of the two pressing plates 22 respectively, the other ends of the two pressing plates 22 are connected with one ends of the two strain gauges 23 respectively, the other ends of the two strain gauges 23 are connected with the upper ends of the two upper inclined rods 25 respectively, in this embodiment, by arranging two groups of damping assemblies 2, the swing and vibration of the flash tank 3 can be effectively coped with.

[0037] In one of the embodiments, referring to FIG. 1 and FIG. 3, a plurality of guide holes are formed in the pressing plate 22, the upper end of the upper inclined rod 25 is fixed with a pressure receiving block 26, a plurality of guide columns 261 are fixed on the pressure receiving block 26, each of the guide columns 261 is slidably inserted into the guide hole one by one, the strain gauge 23 is arranged between the pressure receiving block 26 and the pressing plate 22, when the flash tank 3 vibrates upward, the pressure receiving block 26 vibrates upward and approaches the pressing plate 22, the pressure received by the strain gauge 23 increases, the output pressure of the oil pump 24 increases, so that the pressure of the flash tank 3 received by the pressing plate 22 is equal to the pressure of the hydraulic cylinder 21 received by the pressing plate 22, the guide column 261 prevents the pressing plate 22 from moving laterally.

[0038] In one of the embodiments, referring to FIG. 1 and FIG. 3, the end of the guide column 261 is formed with a limiting protrusion 2611, so as to prevent the pressing plate 22 from being separated from the guide column 261.

[0039] In one of the embodiments, referring to FIG. 1 and FIG. 3, a piston 211 is slidably arranged in the cylinder body of the hydraulic cylinder 21, the output shaft 212 of the hydraulic cylinder 21 is fixedly connected with the piston 211.
