A boiler water deaerator

Abstract

This utility model discloses a boiler water deoxygenation device, belonging to the field of boiler water deoxygenation technology. The device includes an insulated outer shell and a deoxygenation tank. The deoxygenation tank is installed inside the insulated outer shell. A top cover is fastened to the top of the insulated outer shell, and an exhaust port is fixedly connected to the center of the top cover. External steam enters the steam pipe through a conveying pipe and is released into the water through a bubbling nozzle, forming tiny bubbles that rapidly raise the water temperature and promote the release of dissolved oxygen. Simultaneously, water preheated by a spiral coil enters the annular channel of the annular seat through a connecting pipe and is then distributed to multiple surrounding spray nozzles. The spray nozzles atomize the water and spray it evenly onto the lower packing layer. The packing layer is preferably a multi-faceted hollow spherical structure, which effectively prolongs the water droplet residence time and enhances the oxygen release effect. This effectively solves the problems of high energy consumption, low efficiency, and complex operation of traditional deoxygenation equipment.

Description

Technical Field

[0001] This utility model relates to the field of boiler water deoxygenation technology, and more specifically, to a boiler water deoxygenation device. Background Technology

[0002] During the operation of industrial boilers, dissolved oxygen in the feedwater is one of the main factors causing corrosion of the boiler's metal heating surfaces. The presence of oxygen not only shortens the boiler's service life but can also cause serious problems such as poor heat transfer, scaling, and tube rupture, affecting the safe and stable operation of the system. Therefore, deoxygenation devices are needed to remove oxygen from the boiler water.

[0003] Based on the above, the inventors have discovered that most existing thermal deaerators currently use heating to remove dissolved oxygen from water, but this method consumes a lot of energy and is not thorough. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a boiler water deaerator, aiming to achieve a more practical purpose. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a boiler water deoxygenation device that can prevent dissolved oxygen from escaping from the water through heating. However, this deoxygenation method has the problems of high energy consumption and incomplete deoxygenation.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A boiler water deaeration device includes an insulated outer shell and a deaerator. The deaerator is installed inside the insulated outer shell. A top cover is fastened to the top of the insulated outer shell. An exhaust port is fixedly connected to the top center of the top cover. A spiral coil is sleeved on the outside of the deaerator. A water inlet pipe and a connecting pipe are bolted to both sides of the spiral coil, respectively. A steam pipe is installed at the bottom inside the deaerator. One end of the steam pipe is threaded to a conveying pipe, and a bubbling nozzle is fixedly provided on the outer wall of the steam pipe. An annular seat is installed above the deaerator. A spray head is threaded to the bottom of the annular seat, and a packing layer is provided directly below the annular seat.

[0009] Furthermore, a drain pipe is installed at the bottom of the insulation shell, and a valve is installed on one side of the drain pipe.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] This solution incorporates a steam pipe inside the deaerator, with multiple bubble outlets evenly distributed on its outer wall.

[0025] Example:

[0026] Please see Figure 1-4 A boiler water deaeration device includes an insulated outer shell 1 and a deaerator 7. The insulated outer shell 1 is used to reduce heat loss. The deaerator 7 is installed inside the insulated outer shell 1, and a top cover 2 is fastened to the top of the insulated outer shell 1 for opening the deaerator 7. An exhaust port 3 is fixedly connected to the middle of the top of the top cover 2 for discharging oxygen. A spiral coil 8 is sleeved on the outside of the deaerator 7, and the spiral coil 8 and the water inlet pipe 5 are used to preheat the water to improve deaeration efficiency. The water inlet pipe 5 and the connecting pipe 10 are bolted to both sides of the spiral coil 8, respectively. A steam pipe 15 is installed at the bottom inside the deaerator 7, and a conveying pipe 4 is threaded to one end of the steam pipe 15. The steam pipe 15 and the conveying pipe 4 are used to introduce steam into the deaerator 7. A bubbling port 16 is fixedly provided on the outer wall of the steam pipe 15 for heating the water flow and promoting the separation of oxygen from the water. An annular seat 9 is installed above the deaerator 7. A spray head 11 is connected to the bottom of the annular seat 9 by a square thread. The annular seat 9 and the spray head 11 are used to atomize the incoming water and spray it evenly on the surface of the packing layer 12 to increase the deaeration effect. The packing layer 12 is located directly below the annular seat 9.

[0027] See Figure 1 and Figure 3 A drain pipe 13 is installed at the bottom of the heat insulation shell 1, and a valve 14 is installed on one side of the drain pipe 13. The drain pipe 13 and the valve 14 are used to discharge the deoxygenated water into the boiler.

[0028] See Figure 2 and Figure 4 Multiple sets of spray heads 11 are arranged in a ring shape at the bottom of the annular seat 9. A support leg 6 is fixedly connected to the bottom of the heat insulation shell 1. The spray heads 11 are used to atomize the incoming water and spray it evenly on the surface of the filler layer 12 to increase the deoxygenation effect.

[0029] See Figure 1 and Figure 2 The water inlet pipe 5 is connected to an external water pump, and the packing layer 12 is a multi-faceted hollow sphere, which is used to increase the deoxygenation effect.

[0030] See Figure 2 and Figure 4 An annular channel is fixedly provided on the inner side of the annular seat 9. The annular channel is connected to the connecting pipe 10 and the spray head 11 respectively. The annular channel is used for water to enter the spray head 11 respectively.

[0031] See Figure 2 and Figure 4 One side of the connecting pipe 10 is threaded to the spiral coil 8, and the other side of the connecting pipe 10 is threaded to the annular seat 9. The connecting pipe 10 is used to connect the spiral coil 8 and the annular seat.

[0032] See Figure 2 and Figure 3 One side of the conveying pipe 4 is connected to an external steam source, and a regulating valve is installed on one side of the steam source. Multiple sets of bubble outlets 16 are arranged in a ring around the outer wall of the steam pipe 15. The bubble outlets 16 are used to heat the water flow.

[0033] In use: First, the boiler water to be deoxygenated enters the spiral coil 8 through the inlet pipe 5 for preheating. The deoxygenator 7 is equipped with a steam pipe 15, and multiple bubble holes 16 are evenly distributed on its outer wall. After the external steam enters the steam pipe 15 through the conveying pipe 4, it is released into the water through the bubble holes 16, forming small bubbles, which rapidly raises the water temperature and promotes the release of dissolved oxygen. At the same time, the water preheated by the spiral coil 8 enters the annular channel of the annular seat 9 through the connecting pipe 10, and is then distributed to multiple spray heads 11 arranged around it. The spray heads 11 atomize the water flow and spray it evenly onto the packing layer 12 below. The packing layer 12 is preferably a multi-faceted hollow spherical structure, which can effectively prolong the residence time of water droplets and enhance the oxygen release effect. This deoxygenation device has the advantages of high deoxygenation efficiency and good energy saving effect, and can effectively solve the problems of high energy consumption, low efficiency and complicated operation of traditional deoxygenation equipment.
