Description
Technical Field
The utility model relates to the field of compressed air dryers for locomotives, in particular to a dryer air outlet valve with a regeneration air passage.
Background
The athermal regenerated adsorption drier uses pressure swing adsorption principle to eliminate water from compressed gas. The existing dryer has a double-tower structure, and a drying tower and a regeneration tower alternate working and circulating to achieve the drying purpose. The working cycle is divided into two stages of adsorption and regeneration: in the drying stage, the pressure of the drying tower is increased, the partial pressure of water vapor in the air is correspondingly increased, and when the water vapor passes through the drying agent bed layer, the water vapor is adsorbed by the drying agent, so that the partial pressure of the water vapor on the surface of the drying agent is gradually increased, the balance is achieved, and the compressed air is dried; in the regeneration stage, the air pressure in the tower is suddenly reduced, the partial pressure of the water vapor is also reduced, and the water vapor adsorbed in the drying agent is transferred into the air, so that the drying agent is desorbed. The adsorption process is a process in which the free energy of the surface of the drying agent is reduced, and the adsorption process can be performed spontaneously without external energy pushing. The regeneration process is the reverse of the adsorption process, i.e. the process of recovering the free energy of the surface of the desiccant, while the regeneration process is an energy-consuming process. The regeneration process of the athermal regenerated adsorption dryer follows 2 principles: (1) complete regeneration principle: the adsorbed moisture in the adsorption half period T should be completely desorbed and discharged from the tower (T '< T) in a certain time T', and the temperature of the drying agent should reach the set initial temperature before the next adsorption cycle begins; (2) minimum gas consumption principle: at a certain regeneration pressure and discharge temperature, the regeneration tail gas water content is close to saturation, and the regeneration gas consumption is minimum.
The air outlet valve is an important component part of the whole system of the dryer and mainly plays a one-way check role to prevent the compressed air dried by the dryer from flowing back to the drying towers or the two drying towers from 'blowing air', so that the air treatment capacity of the dryer is reduced or the dew point of the compressed air is increased. A regeneration air duct is typically provided throughout the drying system for regenerating the desiccant. The regeneration air channel is generally arranged at the upper end of the drying tower and consists of an upper cover, a regeneration air pipe and a sealing ring. Because the regeneration air hole is arranged on the upper cover of the dryer, the size of the regeneration air hole is troublesome to adjust, and the regeneration air hole is inconvenient to replace only by re-perforating and disassembling a large number of parts. And secondly, the regeneration air path is easy to generate faults at the maximum appearance of the dryer.
