Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of the leakage prevention of the saltwater pool of the cigarette industry boiler, and particularly relates to a leakage prevention pipe fitting for a saltwater pool water intake. BACKGROUND

[0002] In industrial production, heat supply is an indispensable link in many production processes, and the use of boilers for heat supply has become a common phenomenon. In particular, as a major energy consumer, the boiler in the power workshop of a cigarette industry enterprise plays a crucial role. These boilers need to operate stably and reliably to meet the heat demand in the production process, and their operating efficiency and safety are directly related to the production efficiency and safety level of the enterprise. These boiler equipment has strict requirements on water quality during operation and requires a large amount of softened water that meets the standards. The preparation process of softened water usually uses ion exchange technology, that is, when tap water passes through an ion exchanger, the resin inside the ion exchanger will adsorb calcium and magnesium ions in the water, thereby obtaining softened water. However, in this process, the resin will gradually saturate and lose its adsorption capacity, so it needs to be regenerated regularly to restore its adsorption capacity. One of the key steps in resin regeneration is to use high-concentration salt water for flushing.

[0003] Therefore, the preparation and storage of high-concentration salt water in the boiler are particularly important. However, in most early boiler rooms of cigarette industry enterprises, saltwater storage devices are mostly made of finished plastic. These finished plastic containers are lightweight and easy to use, but due to the factory size and material, the volume of the finished plastic containers is small and the strength is not high. At the same time, due to the fixed shape of the finished plastic containers, the matching with the storage location is not good, and it is often difficult to meet the actual production requirements. These problems not only affect the storage efficiency and safety of salt water, but also bring certain hidden dangers to the stable operation of the boiler. With equipment modification and technological upgrading, some cigarette industry enterprises have begun to use salt pools instead of traditional finished plastic containers for industrial salt dissolution and storage. Salt pools have the advantages of large volume, high strength, and good matching, which can effectively solve the problems of finished plastic containers and significantly improve the efficiency of salt water preparation and storage. However, as a strong electrolyte solution, salt water is prone to cause electrochemical corrosion of metals. When the salt pool is abnormally replenished, the salt water is discharged to the sewage pipe through the water intake, and if the leakage prevention measures at the water intake are not in place, salt water leakage may occur at the joint. If the salt pool leaks, salt water will quickly penetrate into the floor interior, causing corrosion of the floor interior steel bars and other materials, which is difficult to remove and may cause safety accidents such as floor collapse.

[0004] Common anti-leakage has stainless steel lining, anti-leakage coating and the like, the stainless steel lining has higher strength and corrosion resistance, can effectively prevent the leakage of salt water, however, its construction cost is higher, the requirement for the sealing property of welding is higher, if the welding is not firm or the sealing is not tight and the like, the leakage problem or safety accident of the water outlet of the salt pool will be caused. Therefore, in order to solve the problem of salt water leakage at the joint of the water outlet of the salt pool for the cigarette industrial boiler, it is necessary to design an anti-leakage pipe fitting with low construction cost, small difficulty and long service life.
