Description

Technical Field

[0001] This utility model relates to the technical field of condensate tanks, specifically a condensate tank for a supercritical unit. Background Technology

[0002] The function of the condensate drain tank is to automatically open the water supply valve to drain the condensate when the water level reaches a set height, and to prevent fresh steam leakage. When the water level is low, the drain valve is automatically closed, and fresh steam leakage is also prevented. Current condensate drain tanks cannot drain water at different heights. Therefore, we propose a condensate drain tank for supercritical units.

[0003] The currently used condensate traps are difficult to handle, which can easily cause pipe blockages during use. They also cannot perform drainage operations for water levels of different heights. Utility Model Content

[0004] The purpose of this utility model is to provide a supercritical unit condensate tank to solve the problems mentioned in the background art, such as the cumbersome handling of impurities in currently used condensate tanks, which easily leads to pipe blockage during use, and the inability to perform corresponding drainage operations for water levels of different heights.

Side drainage mechanisms are fixedly installed on both sides of the outer wall of the condensate tank shell.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a supercritical unit condensate tank, including a condensate tank shell 1 and a drain outlet 3. A waste heat recovery mechanism 2 is fixedly installed on the front of the outer wall of the condensate tank shell 1. The waste heat recovery mechanism 2 includes a connecting pipe 201, a dustproof net 202 and a waste heat recovery device 203. The connecting pipe 201 is fixedly installed on the front of the outer wall of the condensate tank shell 1. The outer surface of the connecting pipe 201 is provided with a dustproof net 202 of matching size. The inner surface of the connecting pipe 201 is connected to and installed with the waste heat recovery device 203. The water temperature inside the condensate tank shell 1 is very high, so the waste heat recovery device 203 can collect waste heat. At the same time, the dustproof net 202 covers the surface of the connecting pipe 201, which can produce a dustproof effect.

[0021] The drain outlet 3 is located at the upper rear of the outer shell 1 of the condensate tank. The outer surface of the drain outlet 3 is provided with a threaded connector 4 of a matching size. The threaded connector 4 is threadedly connected to the outer shell 1 of the condensate tank through the drain outlet 3, and the outer wall of the drain outlet 3 is tightly fitted with the inner wall of the threaded connector 4. Rotating the threaded connector 4 allows it to rotate on the surface of the drain outlet 3, thus opening the drain outlet 3. This allows debris or large particles to be discharged from the opening of the drain outlet 3.

[0022] A supercritical unit 5 is fixedly installed on the upper part of the outer wall of the condensate tank shell 1. Side drainage mechanisms 6 are fixedly installed on both sides of the outer wall of the condensate tank shell 1. Each side drainage mechanism 6 includes a drain outlet 601, a fixed pipe 602, a threaded rod 603, and a sealing plug 604. The drain outlets 601 are fixedly installed on both sides of the outer wall of the condensate tank shell 1. A fixed pipe 602 is welded to one side of the outer wall of each drain outlet 601. A threaded rod 603 of matching size is provided on the inner wall of the fixed pipe 602. A sealing plug 604 is bonded to one side of the outer wall of the threaded rod 603. Rotating the threaded rod 603 allows it to move within the inner wall of the fixed pipe 602, thus driving... The sealing plug 604 blocks the opening of the drain port 601, and at the same time, it can also move away from the inner wall of the drain port 601, thereby opening the notch of the drain port 601. This allows water at different levels to be discharged. The threaded rod 603 is threadedly connected to the drain port 601 through the fixing pipe 602. The drain ports 601 are evenly distributed on the outer shell 1 of the condensate tank. This can drive the sealing plug 604 to stably block and open the drain port 601, thereby allowing the water inside the condensate tank to be discharged. At the same time, opening different drain ports 601 allows water at different levels to be discharged.

[0023] A filter mechanism 7 is fixedly installed on the upper inner wall of the outer shell 1 of the condensate tank. The filter mechanism 7 includes a receiving block 701, a retaining ring 702, and a filter screen 703. The receiving block 701 is welded to the upper inner wall of the outer shell 1 of the condensate tank. The inner wall of the receiving block 701 is provided with a retaining ring 702 of a matching size. The filter screen 703 is fixedly installed on the inner wall of the retaining ring 702. The retaining ring 702 installed on the outer wall of the filter screen 703 is fixed in the inner wall of the receiving block 701. In this way, impurities or large particles will be intercepted by the filter screen 703.

[0024] Working principle: First, place the device in the designated position, rotate the threaded rod 603 to move it within the inner wall of the fixed pipe 602. This causes the sealing plug 604 to block the opening of the drain outlet 601, and also allows the sealing plug 604 to move away from the inner wall of the drain outlet 601, thereby opening the gap in the drain outlet 601. This allows water at different levels to be discharged. Steam inside the supercritical unit 5 enters the interior of the condensate tank shell 1 through the pipe, fixing the insert ring 702 installed on the outer wall of the filter screen 703 to the receiving block 7. Inside the inner wall of 01, debris or large particles are intercepted by the filter screen 703. The rotating threaded pipe 4 rotates on the surface of the drain port 3, thus opening the drain port 3. Debris or large particles are discharged from the opening of the drain port 3. The water temperature inside the outer shell 1 of the condensate tank is very high, so the waste heat recovery unit 203 can collect waste heat. At the same time, the dustproof net 202 covers the surface of the connecting pipe 201, thus producing a dustproof effect. This completes the operation process of a supercritical unit condensate tank.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
