A waterproof shock control method for saturated steam power generation equipment

Abstract

The invention relates to a waterproof impact control method for saturated steam power generation equipment, which belongs to the field of mechanical monitoring. Including data acquisition equipment, data processing equipment and control alarm equipment, the steps are: S1, data processing equipment preset standard saturation curve A related to saturated steam temperature and pressure, water shock alarm curve B and water shock shutdown curve C; S2, The data acquisition device collects the temperature and pressure data of the power machine inlet air of the saturated steam power generation equipment, and the data processing device establishes the front working condition point O in the coordinate system; S3, if the front working condition point 0 is located in the standard saturation curve A Above and between the water impact alarm curve B, the power machine operates as usual; if the front operating condition point 0 is between the water impact alarm curve B and the water impact shutdown curve C, the control alarm device sends an alarm signal; The operating point 0 is outside the water impact shutdown curve C, and the power machine is forced to stop. The invention can realize monitoring and early warning of water impact.

[0002] As iron and steel enterprises continue to tap the potential for energy conservation and emission reduction, low-quality saturated steam produced by vaporization cooling systems such as pelletizing shaft furnaces, steelmaking converters, and steel rolling heating furnaces is also used to generate electricity, and the power machines selected are mostly steam turbines and screw turbines. Expander, because the vaporization cooling system of the existing power machine is waste heat and waste energy recovery, limited by the intermittent production of the host process line, planned shutdown, failure shutdown and other conditions, the saturated steam pressure, temperature, and flow rate fluctuate greatly. Due to long-distance pipeline transportation, it is difficult to guarantee the design value of the steam parameters entering the power machine, and there is even a safety hazard of water impact

These power generators that use low-quality saturated steam to generate electricity are mostly unattended equipment, lacking a complete monitoring method, and relying on operators to monitor the incoming steam parameters and compare them with the saturated steam temperature and pressure comparison table, it is impossible to intervene in advance and timely The purpose of control, often resulting in vicious accidents
