Description

Technical Field

[0001] The invention relates to the technical field of dechlorination in cement production, in particular to a bypass dechlorination system. Background Art

[0002] Cement is a powdery hydraulic inorganic gelling material, which becomes a slurry after being mixed with water. It can harden in the air or in water, and can firmly bond sand, stone and other materials together. It is an indispensable substance in the construction process.

[0003] Cement is affected by the chloride ions of limestone during production. In extreme cases, the chloride ion content in clinker is as high as 0.06% or more, which has seriously restricted cement production. At present, the chloride ion content of ordinary Portland cement is between 0.045% and 0.060%. In some time periods, the chloride ion content is close to the national standard limit, which poses a great quality risk. Due to the high levels of harmful elements such as chlorine, alkali and sulfur, the decomposition furnace, smoke chamber, five-stage cyclone and discharge pipe are severely crusted. Every time the kiln is stopped during off-peak hours, personnel are organized to clean the crust, which poses a safety risk. At the same time, the potassium oxide content in limestone is high, and the alkali equivalent in clinker is 1.0%, resulting in low clinker strength, which does not meet the requirements of the joint-stock company, affects the addition of admixtures in cement, and the cost of cement is high.

[0004] In order to solve the above problems, cement processing plants often use a dechlorination system to perform dechlorination operations during the production of cement. The commonly used methods are: an air intake device extracts a certain amount of high-temperature flue gas from the kiln tail smoke chamber, and immediately cools it through a cooling box to a temperature of about 380°C. At this time, the temperature is much lower than the gasification temperature of chloride ions, so the chloride ions in the flue gas will change from gas phase to solid phase and condense into the powder of the flue gas; then the cooled high-temperature flue gas enters the cyclone for gas-solid separation, and the separated flue gas enters the high-temperature bag filter for dust removal and then enters the exhaust gas treatment system. The collected ash is stored and harmlessly disposed of after reaching a certain amount;

[0005] The existing high-temperature bag dust collector needs to replace the dust bag after using it for a period of time. Therefore, the staff needs to shut down the equipment to replace the dust bag. The replacement process is relatively complicated and takes a lot of time, which can easily affect the production efficiency of cement. Summary of the invention
