[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0025] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0026] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0027] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0028] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0029] Combination Figure 1 , Figure 1 A structural schematic diagram of the device for reducing steam exhaust provided by the utility model is used to illustrate a specific embodiment of the device for reducing steam exhaust provided by the utility model, including:

[0030] A steam pipe 1, one end of which is connected to a condensate tank 3;

[0031] The exhaust steam heat exchanger 2 is a cylindrical shell, and the steam pipeline 1 penetrates and connects the exhaust steam heat exchanger 2, so that a sealing area is formed between the exhaust steam heat exchanger 2 and the steam pipeline 1;

[0032] A condensate drain pipe 7, one end of which is connected to the exhaust steam heat exchanger 2;

[0033] A vent pipe 6, one end of which is connected to a side of the condensate tank 3 away from the ground;

[0034] The first pipeline 8 has one end connected to the side of the side wall of the condensed water tank 3 close to the ground, and the other end connected to the exhaust steam heat exchanger 2 . The first pipeline 8 is provided with a liquid level control valve 4 .

[0035] It should be noted that along the extension direction of the steam pipe 1, the length of the steam pipe 1 is greater than the length of the exhaust steam heat exchanger 2. For example, the length of the steam pipe 1 is 4 meters, and the length of the exhaust steam heat exchanger 2 is 2 meters. Of course, it is not limited to this. The lengths of the steam pipe 1 and the exhaust steam heat exchanger 2 can be adjusted according to actual needs.

[0036] It can be understood that the steam exhaust gas enters from the end of the steam pipe 1 away from the condensate tank 3. When the steam exhaust gas passes through the exhaust steam heat exchanger 2, heat exchange occurs, thereby liquefying into condensed water, and the condensed water enters the condensate tank 3. Since there is water in the condensate tank 3, part of the steam exhaust gas reaches the condensate tank 3 and exchanges heat with the water in the condensate tank 3 to liquefy into condensed water, thereby realizing the recovery of the steam exhaust gas. The steam exhaust gas has a certain pressure and carries gas, so the side of the condensate tank 3 away from the ground is connected to a vent pipe 6 for balancing the pressure in the condensate tank 3. When the condensate in the condensate tank 3 occupies 2 / 3 of the maximum volume of the condensate tank 3, the liquid level control valve 4 is opened, and the condensate in the condensate tank 3 enters the sealing area along the first pipe 8. The condensate in the sealing area continues to increase. When the sealing area is completely filled with condensate, the condensate will be discharged outward along the condensate drain pipe 7, thereby realizing the recovery of the steam exhaust gas.

[0037] Compared with the prior art, the device for reducing steam exhaust provided by the utility model liquefies the steam exhaust into condensed water through the exhaust steam heat exchanger 2 and flows into the condensate tank 3, and the condensate tank 3 further liquefies and condenses the steam exhaust, thereby reducing the steam exhaust, facilitating the recovery of the steam exhaust, effectively reducing the amount of steam on site, eliminating the need to use a steam water transmitter, effectively reducing the cost of spare parts, and having a great significance for ensuring a clean and tidy on-site environment.

[0038] In some optional embodiments, continue to refer to Figure 1 The device for reducing steam exhaustion provided in this embodiment further includes:

[0039] The second pipeline 9 has one end connected to the first pipeline 8 between the liquid level control valve 4 and the exhaust steam heat exchanger 2 , and the other end connected to the vent pipe 6 . The second pipeline 9 is provided with a connecting valve 5 .

[0040] It can be understood that there is also gas in the condensed water in the condensed water tank 3. When the liquid level control valve 4 is opened to discharge the condensed water in the condensed water tank 3 to the sealing area, the connecting valve 5 must also be opened to discharge the gas in the condensed water along the second pipeline 9 to the vent pipe 6, and then discharged into the air to balance the pressure, thereby ensuring the safety of the device for reducing steam exhaust provided in this embodiment.

[0041] In some optional embodiments, the thickness of the steam pipe 1, the condensate drain pipe 7, the first pipe 8 and the second pipe 9 is greater than or equal to 5 mm;

[0042] The wall thickness of the exhaust steam heat exchanger 2 and the condensed water tank 3 is greater than or equal to 5 mm.

[0043] The nominal diameter of the steam pipe 1 is 80 mm, the nominal diameter of the exhaust steam heat exchanger 2 is 150 mm, and the nominal diameters of the first pipe 8 and the second pipe 9 are 25 mm.

[0044] It can be understood that the specific parameters of the steam pipe 1, the condensate drain pipe 7, the first pipe 8, the second pipe 9, the exhaust steam heat exchanger 2 and the condensate tank 3 can be adjusted according to actual needs. This embodiment does not impose specific restrictions on this, as long as it can meet the safety production requirements.

[0046] A steam pipe 1, one end of which is connected to a condensate tank 3;

[0047] The exhaust steam heat exchanger 2 is a cylindrical shell, and the steam pipeline 1 penetrates and connects the exhaust steam heat exchanger 2, so that a sealing area is formed between the exhaust steam heat exchanger 2 and the steam pipeline 1;

[0048] A condensate drain pipe 7, one end of which is connected to the exhaust steam heat exchanger 2;

[0049] A vent pipe 6, one end of which is connected to a side of the condensate tank 3 away from the ground;

[0050] A first pipeline 8, one end of which is connected to the side of the side wall of the condensed water tank 3 close to the ground, and the other end of which is connected to the exhaust steam heat exchanger 2. The first pipeline 8 is provided with a liquid level control valve 4;

[0051] Methods, including:

[0052] Add water to the condensate tank 3 and the sealing area;

[0053] The end of the steam pipe 1 away from the condensate tank 3 receives the steam exhaust steam;

[0054] When the condensed water in the condensed water tank 3 occupies 2 / 3 of the maximum volume of the condensed water tank 3 , the liquid level control valve 4 is opened.

[0056] When the liquid level control valve 4 is opened, the communication valve 5 is opened.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
