There are 3 sets of dryers in the CFB boiler installation in Maoming Petrochemical Refinery. During operation, the dryer needs to be drained to prevent the wind system from carrying water. For the original design reasons, the steam traps of the dryer are exhausted in a straight row, and the diameter of the hydrophobic pipe is small and easy to block. In order to reduce the blockage, the team members will generally open up straight, which will result in greater waste. Moreover, it is straight and large, and the hydrophobic noise is very large, which affects the working environment on site.
The thermoelectric division power workshop concentrates on the wisdom of the three major technical and technical backbones of the process, equipment and safety, and tries to modify the steam trap of the dryer.
They thoroughly analyzed the structure, working principle, and process flow of the steam trap, and proposed a modification plan.
The way to think of it, they took the initiative to find suitable materials from the waste repository, create conditions, and transform the straight drain pipes of the dryer. First, reduce the number of drain pipes in the existing dryer. Connect one DN50 line from the intercooler and the dehydration tank, merge them into one way, and add a condensate tube of DN150 of about 1 meter long. The second is to use the imported DRAIN-ALL steam trap on the drain pipe, matching the corresponding instrument accessories.
On June 3, the transformation was successfully completed. After half a month of operation, the hydrophobic method was changed, avoiding the direct discharge of hydrophobic waste, reducing the waste of industrial wind and greatly reducing the noise, ensuring the physical and mental health of the employees, and also played a role. The purpose of energy saving. According to statistics, after the transformation, the industrial wind will be saved by 15 liters/second, and the annual cost savings will be about 720,000 yuan.
