Description

Technical Field

[0001] The utility model relates to the field of steam turbine generators, in particular to an ion exchanger device for a generator's constant cooling water system. Background Art

[0002] In the generator stator cooling water system, approximately 10% of the stator cooling water flows into an ion exchanger to reduce the generator's conductivity. The ion exchanger contains resin, which reduces the water's conductivity as it passes through it. Exhausted resin requires removal and replacement, a difficult on-site operation. Summary of the Invention

[0003] In view of this, the utility model provides an ion exchanger device for a generator cooling water system, which meets the operating requirements of the turbine generator cooling water system and reduces the difficulty of replacing the resin of the ion exchanger.

[0004] The technical solution of the utility model is that it consists of an upper head cover, a cylinder, an inlet connecting pipe, an inlet filter pipe, an outlet connecting pipe, an outlet filter pipe, an exhaust pipe, a sewage pipe, a handwheel hanger, and supporting legs. The inlet connecting pipe is installed on the upper part of the cylinder, and the outlet connecting pipe is installed on the lower part of the cylinder; inside the cylinder, the inlet connecting pipe is connected to the inlet filter pipe, and the outlet connecting pipe is connected to the outlet filter pipe; the exhaust pipe is installed on the upper part of the upper head cover, and the sewage pipe is installed on the side of the lower part of the cylinder, and valves are installed on the exhaust pipe and the sewage pipe.

[0005] The beneficial effects of the utility model are as follows: the utility model designs an ion exchanger device structure of a constant cooling water system, has the characteristics of mature design, simple structure, safe and reliable operation, and fully meets the operation requirements of the steam turbine generator.

[0009] The technical solutions of the present application are further described in detail below in conjunction with specific embodiments. To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different structures.

[0010] like Figure 1 As shown, the technical solution of the utility model is: an ion exchanger device for a generator cooling water system, comprising an upper head cover 1, a cylinder 2, an inlet connecting pipe 3, an inlet filter pipe 4, an outlet connecting pipe 5, an outlet filter pipe 6, an exhaust pipe 7, a sewage pipe 8, a handwheel hanger 9, and support legs 10. The inlet connecting pipe 3 is mounted on the upper part of the cylinder 2, and the outlet connecting pipe 5 is mounted on the lower part of the cylinder 2.

[0011] Specifically, inside the cylinder 2, the inlet connecting pipe 3 is connected to the inlet filter pipe 4 to prevent impurities in the constant cooling water system from being brought into the cylinder and contaminating the resin. The outlet connecting pipe 5 is connected to the outlet filter pipe 6 to prevent the resin from leaking into the constant cooling water system. The drain pipe 8 is installed on the lower side of the cylinder 2. The drain pipe 8 bends downward inside the cylinder 2 and leaves a gap with the bottom of the cylinder to prevent the resin from being drained out of the ion exchanger when the drainage operation is performed before replacing the resin. The handwheel hanger 9 is installed on the top of the upper head cover 1 to facilitate opening or closing the upper head cover 1. The exhaust pipe 7 is installed on the top of the upper head cover 1 to discharge the gas inside the cylinder 2 so that it is completely filled with water. The support leg 10 is installed at the bottom of the cylinder 2 to provide stable support.

[0012] The above-described embodiments are merely preferred embodiments of the present invention. Those skilled in the art will appreciate that the present invention is not limited to the above-described embodiments and that various modifications and variations may be made to the present invention without departing from the scope and spirit of the present invention. These modifications and variations are intended to encompass such modifications and variations as long as they fall within the scope of the claims and their equivalents.
