Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments:

As shown in Figure 1-3, a new type of water cap for a resin exchange reactor includes a water cap frame 1, a Johnson mesh wire 7, a valve seat 5, a valve plate 4 and a sleeve nut 6. The front end of the water cap frame 1 is The shaft-shaped thread segment is connected with a Johnson mesh winding wire 7 by welding at the rear end of the water cap frame 1 , and a ventilation hole 1-1 is formed inside the thread segment and the Johnson mesh winding wire 7 . The threaded section of the water cap frame 1 is matched with an upper fastener and a lower fastener, and is clamped and fixed on two end surfaces of the reactor flower plate 14 by the upper fastener and the lower fastener. Specifically, the upper fasteners are two nuts A2 and gaskets A3, and the top is provided with double nuts to ensure reliable installation; the lower fasteners are nuts B8 and gaskets B9, and the bottom surface of the threaded section of the water cap frame 1 is provided with There is a backing plate 17, and the valve seat 5 is sleeved on the threaded section and clamped between the backing plate 17 and the nut B8. The sleeve nut 6 is installed on the inner side of the valve seat 5 and is threadedly connected to the threaded section of the water cap frame 1 .

The specific structure of the exhaust passage is as follows: the threaded section of the water cap frame 1 is uniformly distributed with ventilation holes A10 along the circumferential direction. In this embodiment, there are 8 ventilation holes A10 uniformly distributed with a diameter of Φ5. The sleeve nut 6 has ventilation holes B11 evenly distributed along the circumferential direction. The ventilation holes A10 are connected with the gap 13 through the ventilation holes B11. . The inner side wall of the valve seat 5 is provided with a step B16, the outer side wall of the sleeve nut 6 is provided with a step A15, the height of the step B16 and the step A15 are the same, and the valve plate 4 rests on the plane formed by the step B16 and the step A15. Matching with the gap 13 , that is, the valve plate 4 covers the vertically arranged gap 13 . The upper part of the valve seat 5 is uniformly distributed with a circle of exhaust holes 12 along the circumferential direction, and the exhaust holes 12 are located above the gap 13 . In this embodiment, there are 8 exhaust holes 12 evenly distributed with a diameter of Φ5; the passage between the gap 13 and the exhaust holes 12 is opened and closed by the valve plate 4 .

As shown in Figures 1, 3, and 4, during operation, the ventilation hole 1-1 enters the water cap frame 1 and is discharged from the skein-shaped winding gap, and then enters the resin layer (the resin layer is under the gasket B9, distributed in the The entire periphery of the device (the resin layer is not shown in the figure), at this time, the reaction gas flows into the gap 13 between the valve seat 5 and the sleeve nut 6 through the vent holes A10 and B11 on the water cap skeleton. The Johnson mesh winding 7 adopts a rock-shaped structure, and the rock-shaped structure can reduce resin abrasion, blockage, and resistance drop. Once the resin is broken and the Johnson net is blocked, the reaction gas cannot enter the resin layer through the winding wire normally. At this time, the pressure on the upper surface of the reactor flower plate 14 increases. When the pressure difference between the two sides reaches a certain value, the valve plate 4 on the base Its own gravity cannot overcome the pressure difference. At this time, the valve plate 4 is lifted by the air flow, and the air flow enters the resin layer through the exhaust hole 12 on the valve seat 5 (the flow direction of the air flow is shown by the arrow in Figure 1), and the reactor flower plate 14 (resin exchange The pressure difference between the two sides of the components in the reactor is reduced, and further the pressure difference between the two sides reaches a balance, so as to ensure that the reactor flower plate 14 is not deformed and the equipment runs stably.

It can be understood that, for those skilled in the art, equivalent replacements or changes to the technical solutions and inventive concepts of the present invention shall fall within the protection scope of the appended claims of the present invention.
