BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 This is a structural schematic diagram of a deaerator steam-water separation device in one embodiment of the present disclosure. DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present disclosure, the embodiments of the present disclosure are further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present disclosure, the embodiments of the present disclosure are further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1 As shown, an embodiment of the present disclosure provides a deaerator steam-water separation device 100 , including a steam-water inlet pipe 110 , a steam-water separation pipe 120 and an exhaust pipe 130 .

[0025] The inlet of the steam-water inlet pipe 110 is used to be connected to the outlet of the deaerator 200 , and the outlet of the steam-water inlet pipe 110 is connected to the inlet of the steam-water separation pipe 120 .

[0026] The top outlet of the steam-water separation pipe 120 is connected to the inlet of the exhaust pipe 130 .

[0027] A plurality of separation baffles 140 are arranged at intervals along the length direction of the steam-water separation pipeline 120 . The separation baffles 140 are used to separate the steam-water mixture entering the steam-water separation pipeline 120 .

[0028] It should be noted that the plurality of separation baffles 140 may be distributed at equal intervals or at unequal intervals, and may be selected according to actual needs. In addition, there is no specific requirement for the number of separation baffles 140, and may be selected according to actual needs. The number may be 3, 4, or more. Figure 1 As shown, in this embodiment, the number of separation baffles 140 is 4, and the 4 separation baffles 140 are distributed at equal intervals.

[0029] Specifically, the steam-water mixture produced by the deaerator 200 enters the steam-water separation pipe 120 through the steam-water inlet pipe 110, and the steam-water mixture is separated into steam and water under the action of the separation baffle plate 140. The separated condensed water enters the bottom of the steam-water separation pipe 120, and the separated gas continues to rise and is discharged through the exhaust pipe 130.

[0030] The deaerator steam-water separation device of the disclosed embodiment is provided with a steam-water separation pipeline, and a plurality of separation baffles are arranged in the steam-water separation pipeline at intervals along the length direction thereof, and the separation baffles are used to separate the steam-water mixture entering the steam-water separation pipeline, and the separated gas is discharged along the exhaust pipe. Through the steam-water separation device, the discharged gas can be free of water, and water and ice will not accumulate on the roof in winter, and the roof waterproof layer will not be damaged, thereby ensuring the safe and stable operation of the equipment and saving manpower and material resources.

[0031] For example, Figure 1 As shown, the edge area of ​​the separation baffle 140 is fixed to the inner side wall of the steam-water separation pipe 120. Specifically, the edge area of ​​each separation baffle 140 is welded to the inner side wall of the steam-water separation pipe 120.

[0032] The separation baffle 140 is provided with a plurality of through holes 150, through which the separated gas enters the exhaust pipe 130, and the separated condensed water flows into the bottom of the steam-water separation pipe 120 along the through holes 150. The plurality of through holes 150 are distributed in a matrix.

[0033] Specifically, when the steam-water mixture entering the steam-water separation pipe 120 contacts the separation baffle 140, the water vapor will condense to form condensed water, and the condensed water can flow into the bottom wall of the steam-water separation pipe 120 along the multiple through holes 150, and the gas continues to rise along the multiple through holes 150 and is discharged through the exhaust pipe 130.

[0034] In this embodiment, the steam-water mixture can be separated into steam and water by the separation baffle, and the separated gas enters the exhaust pipe along the through hole, and the separated condensed water flows into the bottom of the steam-water separation pipe along the through hole, so that the exhausted gas does not contain water, and will not cause water and ice accumulation on the roof in winter, and will not cause damage to the roof waterproof layer, thereby ensuring safe and stable operation of the equipment and saving manpower and material resources.

[0035] For example, Figure 1 As shown, the separation baffle 140 protrudes toward the outlet direction of the steam-water separation pipeline 120. In other words, the separation baffle 140 is a baffle inclined downward from its center. Preferably, in this embodiment, the separation baffle 140 is conical.

[0036] In this embodiment, the separation baffle protrudes toward the outlet direction of the steam-water separation pipe, so that the condensed water can flow into the steam-water separation pipe better along the through hole.

[0037] For example, Figure 1 As shown, the deaerator steam-water separation device 100 further includes a drain pipe 160 , the inlet of the drain pipe 160 is connected to the bottom of the steam-water separation pipe 120 , and the outlet of the drain pipe 160 is used to be connected to the inlet of the deaerator 200 .

[0038] Specifically, the separated condensed water flows into the bottom of the steam-water separation pipe 120 and then enters the deaerator 200 through the drain pipe belt 160 for recycling.

[0039] In this embodiment, the separated condensed water is discharged in time through the drain pipe to prevent the accumulated water in the steam-water separation pipe from overflowing to the outside after being full and causing ice accumulation again; the separated condensed water is returned to the deaerator through the drain pipe to ensure that most of the qualified drain water is recovered, which is energy-saving and environmentally friendly.

[0040] For example, Figure 1 As shown, the outlet of the steam-water inlet pipe 110 is connected to the side wall of the steam-water separation pipe 120 .

[0041] The steam-water inlet pipe 110 is inclined downward and the angle between the steam-water inlet pipe 110 and the steam-water separation pipe 120 is in the range of 75° to 80°.

[0042] In this embodiment, the steam-water inlet pipe is connected to the side wall of the steam-water separation pipe at an angle, so that the gas in the steam-water mixture can be better separated.

[0043] For example, Figure 1 As shown, the diameter of the exhaust pipe 130 and the diameter of the steam-water inlet pipe 110 are both smaller than the diameter of the steam-water separation pipe 120. Increasing the diameter of the steam-water separation pipe 120 can, on the one hand, facilitate the arrangement of multiple separation baffles 140 in the steam-water separation pipe 120 for steam-water separation, and on the other hand, can store the separated condensed water to ensure that most of the condensed water flows back to the deaerator 200.

[0044] For example, Figure 1 As shown, the outlet of the exhaust pipe 130 includes a first sub-outlet 131 and a second sub-outlet 132; there is a preset angle between the first sub-outlet 131 and the second sub-outlet 132. Preferably, in this embodiment, the outlet of the exhaust pipe 130 is in a "Y" shape. That is, the outlet of the exhaust pipe 130 is not vertically distributed, which can prevent rainwater from entering the steam-water separation pipe 120 through the outlet of the exhaust pipe 130 when it rains, affecting the steam-water separation effect.

[0045] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the embodiments of the present disclosure, but the embodiments of the present disclosure are not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the embodiments of the present disclosure, and these modifications and improvements are also considered to be within the protection scope of the embodiments of the present disclosure.
