With the continuous development of China's economy and chemical industry, natural gas rotary kilns are mainly used in the chemical and metallurgical industries. They are a high-quality equipment that discharges water and slag deposited in the equipment to extend its service life. Therefore, the following article will explain in detail the issues of regular and continuous discharge of this equipment.
Regular discharge is mainly carried out for the lowest part of the rotary kiln, and the amount of regular discharge depends mainly on the quality of the water supply. Generally, it is carried out every 24 hours. However, if the water supply for the equipment is clean condensate water and chemical desalinated water or a small amount of softened water is used as supplementary water, the interval of regular discharge can be greatly extended. At the same time, there will definitely be a time interval for regular discharge. How to control this interval and do a good job of regular control. In fact, the specific interval and operation duration of regular discharge of rotary kilns are determined by the workshop based on the quality of furnace water.
The main function of continuous discharge is to remove soluble salts from the furnace water, so as to maintain the salt content and other control indicators of the rotary kiln water within the specified range. Therefore, continuous discharge should be carried out from the location with the highest salt concentration. Continuous sewage discharge can also discharge some fine-grained water slag, but the sedimentation of coarse-grained water slag in the lower part still needs to be discharged through regular sewage discharge.
