Peach red willow green, graphite heat exchanger shared. Since the company was established, it has improved the quality of graphite equipment, improved after-sales service, and strong technical force. It has always been guided by science and technology, and constantly develops new products. "Perfect and perfect service" business philosophy has become the country's important graphite equipment production base. The service is perfect. At present, the dry-flow graphite heat exchanger is selected for the dry flow. This type of graphite heat exchanger has high structural strength, high temperature and pressure resistance, good impact resistance, high heat transfer efficiency, long service life and easy maintenance. Features: The graphite heat exchange block adopts standard unit blocks, and the graphite blocks are sealed with polytetrafluoroethylene O-rings, which can be planned for multi-process, vertical and horizontal use. Planning temperature: -40 ～ 220 ℃, planning pressure: -0.1 ～ 0.8MPa. Teflon seal is used and a pressure spring is installed as a compensation device. The graphite heat exchange block does not have a central hole, and the water hole passes directly from one side to the other. The material holes are covered with heat exchange blocks to improve the data utilization rate. There are two groups of unconnected flow channels drilled on the graphite block, and the two groups are at right angles. Two different fluids achieve heat exchange through the two groups of flow channels. It is intended that the equipment with the same heat exchange area is small in size and more compact, and has the advantages of high heat transfer efficiency, stability, reliability, impact resistance and convenient maintenance.
When the graphite heat exchanger tubes are leaking, the conventional detection method is to test the graphite tubes one by one in the tubular graphite heat exchanger. This method is the most thorough, but it is too slow. Since the graphite tube was suddenly damaged during operation, it was impossible to clean the heat exchanger with hot water. Because about 80% of the shell of the tubular graphite heat exchanger is made of carbon steel, if the acid water is cleaned, it will cause corrosion on the shell of the heat exchanger. At this time, a high-pressure cleaner must be used to clean the pipes one by one. It takes about 3 minutes to clean each tube. Before the test, the active steam regulating valve and manual master valve of the heat exchanger should be closed, the heat exchange liquid discharge pipe of the heat exchanger should be removed, and the valve should be installed on this interface for testing. Used to drain water from the shell side.
Peach willow green, graphite heat exchanger shared, love what I love, always go, high-quality graphite heat exchanger is like a mirror, you laugh when users laugh, advanced technology, heavy safety, energy saving and environmental protection, heat exchange block chooses standard unit block, graphite The blocks are sealed with polytetrafluoroethylene O-rings. The planned temperature is -20 to 170 ° C and the planned pressure is 0.4MPa-0.8Mpa. It has high structural strength, strong temperature and pressure resistance, good impact resistance, and high heat transfer efficiency. Long life and easy maintenance.
