How to write a summary of cold and antifreeze?

1, it's very cold in winter, so it's particularly important for all majors to do a good job in cold and antifreeze. This year, the professional ash removal equipment runs stably and safely. In order to ensure that equipment and pipelines do not freeze during operation, specific measures for internal cold prevention and freezing prevention have been specially formulated, and a working group for cold prevention and freezing prevention has been set up, which has achieved the quality goal that no incidents that affect the normal operation of equipment due to freezing during operation and achieved safe operation without freezing. The following is a report on the cold and antifreeze work of ash removal specialty.

2. Technical measures for preventing cold and freezing in ash removal specialty: all electric heating and heat tracing devices are put into operation (including: ash hopper of electrostatic precipitator, incubator of electrostatic precipitator, slag bin, heat tracing cable of flue gas online detection system, heat tracing cable of air compressor air storage tank blowdown pipeline, heat tracing cable of ash storage instrument air storage tank blowdown pipeline).

3. When the slag water circulation system is not put into operation, the water drain valve should be opened to drain the accumulated water in the channel. When it is closed for a long time, the water in the pool should be drained.

4. When the slurry pump is shut down for a long time, the internal water should be exhausted. During the shutdown of the slag bin, the internal water should be drained, the main backwashing water door should be closed, and the slag discharge door should be operated regularly in each shift.

5. In winter, the water in the sewage pool of the ash storage yard is emptied, and the water in the pipeline is emptied. When the gasification fan is turned off, the valve will be closed even though there is water in the pipeline.

6. When the air compressor is completely closed, the main cooling water gate should be closed and the drain valve should be opened to release the water in the channel.

7. When the economizer is closed, the dome valve cooling water of the economizer shall be drained and the valve shall be closed. When the heating in the distribution room is not good, the distribution board should be put into heating.

8. When the zero meter heating of the boiler is not good, the hydraulic drive device should be electrically heated.

9. Close all doors and windows of the ash handling complex. Put all heating devices in the slag bin, air compressor room and storage ash storage.

10, the operating personnel on duty regularly measure and record the temperature of the equipment and workshop under their jurisdiction.

1 1. For the defects related to cold and antifreeze, we will strive to achieve "big defects do not stay overnight, small defects do not stay overnight", strengthen the assessment of cold and antifreeze work, and link it with performance pay. Actively cooperate with the leaders in the inspection and assessment of professional cold and antifreeze work.

12. Shortcomings in the cold-proof and anti-freezing work of ash handling specialty. Due to the limited working experience of operators, some defects and hidden dangers cannot be found in time when the equipment is running, and the problems cannot be effectively and accurately judged, which has a certain impact on the cold-proof and anti-freezing work. Coupled with the poor sense of responsibility of individual personnel, the inspection is not detailed enough, which will also affect the progress of cold and antifreeze work. Under the wise guidance of the leaders, the hard work of the operators of ash removal specialty, and the strong cooperation and support of relevant majors and departments, the specialty runs safely and stably, without a freezing incident, and the established goal has been achieved. Of course, we will also sum up our experience and make preparations to lay a good foundation for the cold and antifreeze work in the coming year. ?
