Device and equipment combined graphite synthesis furnace lamp holder modification li longhai cangzhou chemical industry group co., LTD., cangzhou, hebei, 61 keywords synthesis furnace; Lamp holder; Retrofit: the structure of lamp holder of synthetic furnace was retrofit for hydrogen chloride with low purity, high content of hydrogen chloride and high content of free chlorine during operation of synthetic furnace.

Classification number in the call id my factory 10000 1 12442 415 of high purity graphite synthetic furnace burner using acid is 1 hydrogen entry and chlorine gas entrance by quartz tube mixed combustion is the most important is now 5 months before the purity of hydrogen chloride gas gen purity to an average of 76. If you want to improve the purity, easy to cause the pure acid contains free chlorine, and chlorine ion membrane alkali production process is not allowed, it can damage carbon sintered tube in salt water filters, sintered tube not only expensive, but it is damage will cause the quality of brine filtration is unqualified, and so cannot be the end of the production of qualified products; In addition, the free chlorine also damages the chelating resin in the resin tower, resulting in resin poisoning and unqualified secondary brine quality. If it is not handled properly, the ionic membrane on the electrolyzer will be completely discarded and the loss will be serious. The low purity of hydrogen chloride gas also increases the hydrogen content in the system, which is explosive and prone to accidents, increasing the danger factor of the system. There are many manufacturers in the process of operation due to the high hydrogen content of the system led to acid fog catcher explosion synthesis furnace explosion-proof film burst open the circulation tank was detonated and other accidents, so the reduction of hydrogen content of the system is particularly necessary.

Using the old lamp holder we also found that the synthetic combustion is not uniform and stable, the color of the flame is not easy to observe, so the operator needs to constantly adjust the valve opening to adjust, increased labor intensity and instability factors, furnace pressure value is also high, so that the life of the whole system is reduced.

In view of the above shortcomings, we modified the lamp holder of the synthetic furnace and decided to change 1 hydrogen and 1 chlorine to 2 hydrogen and 1 chlorine 1. After repeated experiments, it was finally successful. The purity of hydrogen chloride gas was increased to 96, and free chlorine was not contained in the system. See details before and after the transformation 1.

Phase b labor intensity flux change workers rely on during the 6 times of continuously adjusting the opening of hydrogen chloride valves to make free chlorine to ensure the safety and stability of the system
