Description
Technical Field
The utility model belongs to the industrial field, especially, splash device is prevented in blowdown of performance test pressure measurement station.
Background
The energy-saving and emission-reducing work of the thermal power generating unit is along with the whole life cycle of the commercial operation of the unit, and a large amount of performance tests are required to be carried out during the whole life cycle, particularly before and after maintenance or before and after modification, so that more accurate economic data of the unit can be obtained. However, the pressure measuring point used in the performance test of the thermal power plant is often used frequently, so that a great amount of dirt such as dust, silt, welding slag and the like is accumulated inside the pressure transmission pipeline, the primary valve, the secondary valve and the blow-down valve, and the whole pressure transmission path is blocked. Therefore, after the pressure transmitter special for performance test is installed in place, if the problem of pressure transmission resistance is not well handled, the pressure measurement distortion is caused by the unsmooth pressure transmission channel. The above conditions have the most prominent influence on the differential pressure measuring point for measuring the flow, and the measured differential pressure causes the calculated flow to have a non-negligible deviation, and the individual conditions even cause the whole performance test work to be forced to be delayed.
In the prior art, when the condition that a pressure transmission channel (a pressure transmission pipe, a primary valve, a secondary valve or a blow-down valve) is blocked at the pressure (or differential pressure) measuring point special for the performance test is processed, a blow-down valve is usually opened, a pressure transmission pipeline and a related valve body are knocked according to the blow-down condition, the blow-down state (the dirty degree, the impact strength and the unblocked degree) of a blow-down outlet is observed until clean water flows out of the blow-down outlet stably, and then the condition that the dirt in the pressure transmission pipe is discharged and the pressure transmission is unblocked can be preliminarily judged.
In the sewage discharging process, the medium (usually sewage) in the pressure transmission pipeline is directly discharged to the air from the sewage discharging port. A sewage discharge channel is arranged at a sewage discharge port of part of power plants, and sewage can be discharged into the channel; some power plants are not provided with a sewage discharge channel, and a sewage discharge outlet faces the ground or a component. The above drain outlet setting mode often has certain potential safety hazard in the performance test work.
In the early stage, the middle stage and the later stage of the pressure transmission system pollution discharge, the medium in the pressure transmission pipeline can be sprayed out instantly, and when the pressure and the temperature of the medium are higher, the pollution discharge port which is configured conventionally has great potential safety hazard to the pressure transmission system pollution discharge. Particularly, in the process of treating the case that the pressure transmission system is blocked tightly, after the relevant position is knocked, the pressure transmission pipe is usually instantly unblocked at a certain moment, and the work substance splashed out forms no small safety threat to operators.
At present, no better method is available for safely and effectively solving the problems, and the safety consciousness and experience judgment of personnel are basically relied on.
