Abstract
Description
Technical Field
[0001] This utility model relates to the field of secondary steam recovery and utilization technology, specifically to a steam pipeline device that effectively removes condensate during use. Background Technology
[0002] MVR is short for mechanical vapor recompression. Its principle is to compress low-temperature steam using a steam mechanical compressor, increasing its temperature, pressure, and enthalpy, before condensing it in a heat exchanger to fully utilize the latent heat of the steam.
[0003] In existing sodium sulfate crystallization processes, the steam discharged from the crystallization separator is secondary steam. This secondary steam can be compressed by a steam mechanical compressor and reused. Specifically, for example... Figure 1 As shown, the steam mechanical compressor 1 is connected to the horizontal inlet pipe 2 of the secondary steam, allowing the secondary steam to enter the steam mechanical compressor 1 for compression via the pipeline. However, the secondary steam contains a certain amount of condensate. This condensate must be removed before the secondary steam enters the steam mechanical compressor 1 to prevent gas-liquid carryover, which could cause unstable operation of the steam mechanical compressor 1. Figure 1 As shown, a drain pipe 3 is connected to the bottom of the horizontal intake pipe 2 near the steam mechanical compressor 1. The drain pipe 3 is connected to a condensate tank 4, and the condensate tank 4 is connected to a condensate pump 5, which then pumps away the condensate flowing into the condensate tank 4 for other uses. In the above process, the condensate in the secondary steam in the intake pipe and the horizontal intake pipe 2 is pushed to the bottom of the horizontal intake pipe 2 by gravity and then flows to the inlet of the drain pipe 3. However, since the secondary steam entering the steam mechanical compressor 1 has a certain flow rate, during the process of entering the steam mechanical compressor 1, it will again blow away the condensate at the bottom of the horizontal intake pipe 2 and carry some of the condensate back into the steam mechanical compressor 1, thus affecting the operation of the steam mechanical compressor 1. Therefore, how to further remove the condensate in the secondary steam before it enters the steam mechanical compressor 1 is an urgent problem to be solved. Utility Model Content
[0004] To solve the above technical problems, the utility model provides a steam pipeline device, including with steam mechanical compressor connection's horizontal air inlet pipe, and higher than horizontal air inlet pipe with horizontal air inlet pipe's other end connection's air inlet pipe, air inlet pipe is vertical air inlet pipe or inclined air inlet pipe, in horizontal air inlet pipe and air inlet pipe's connection place's position, air inlet pipe continues to extend below horizontal air inlet pipe and forms the liquid accumulation tank of air inlet pipe or air inlet pipe is connected with liquid accumulation tank through the connecting pipe of air inlet pipe below horizontal air inlet pipe setting.In the above scheme, by changing the position of the drain, the position of the drain on the lower pipe wall of the horizontal air inlet pipe is moved to the end position of the horizontal drain pipe. The principle is that before the secondary steam in the air inlet pipe enters the horizontal air inlet pipe, the condensed water in the secondary steam directly falls into the extended part of the air inlet pipe or the connecting pipe by gravity. At this time, the secondary steam entering the horizontal air inlet pipe greatly reduces the content of condensed water. At the same time, the bottom of the horizontal air inlet pipe is basically free of condensed water. Since the length of the horizontal air inlet pipe is generally set to be relatively short, there is no more condensed water formed at the bottom of the horizontal air inlet pipe. The secondary carrying (specifically, the airflow blows the condensed water at the bottom of the horizontal air inlet pipe, and then carries the condensed water into the steam mechanical compressor) is reduced. Therefore, the condensed water in the secondary steam entering the steam mechanical compressor is greatly reduced, ensuring the stability of operation. Specifically, there are two technical solutions. One is to set the liquid accumulation tank by extending the air inlet pipe. The other is to connect the liquid accumulation tank through the connecting pipe. The diameter of the part of the connecting pipe connecting the air inlet pipe is close to or preferably consistent with the diameter of the air inlet pipe.
[0005] In an embodiment, a liquid blocking net is arranged in the pipeline at the connection between the horizontal air inlet pipe and the air inlet pipe. By arranging the liquid blocking net, the condensed water in the secondary steam can adhere to the net and reduce the speed when passing through the liquid blocking net, facilitating dripping.
[0006] In an embodiment, a liquid blocking structure is arranged in the pipeline of the extended part of the air inlet pipe or in the connecting pipe. By arranging the liquid blocking structure, the secondary carrying caused by the secondary steam impacting the liquid already dropped into the liquid accumulation tank can be prevented, and the stable operation of the steam mechanical compressor can be affected.
[0007] In an embodiment, the liquid blocking structure is a mesh structure or a plate structure with openings. The condensed water can drip, and the liquid caused by impact can be blocked.
[0008] In an embodiment, the liquid blocking structure is a horn structure. The above functions are further realized, so that the liquid caused by impact is blocked and flows down along the side wall, and the effect is better.
[0009] In one embodiment, a liquid pump connected to the liquid accumulation tank is further included. BRIEF DESCRIPTION OF DRAWINGS

[0018] In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as there is no conflict.
[0019] Example 1
[0020] As Figure 2 shown, the utility model discloses a steam pipeline device, which is mainly applied in the sodium sulfate crystallization process of wastewater treatment, specifically refers to the device for reusing secondary steam volatilized from a crystallization separator, of course, the steam pipeline device is not limited to the sodium sulfate crystallization process, and can be used in any process that generates secondary steam which needs to be compressed by a steam mechanical compressor and then reused. Specifically, it comprises a horizontal air inlet pipe 2 connected with a steam mechanical compressor 1, and an air inlet pipe 6 higher than the horizontal air inlet pipe 2 and connected with the other end of the horizontal air inlet pipe 2. The horizontal air inlet pipe 2 is a conventional air inlet pipeline of the steam mechanical compressor 1, and its length is determined according to the design of the equipment, but generally will not be too long, about 1m to 2m, but not limited to this range. The air inlet pipe 6 is a vertical air inlet pipe or an inclined air inlet pipe, which refers to the angle of the air inlet pipe, and can be determined according to the comprehensive equipment design. The vertical structure, i.e. the vertical air inlet pipe, is preferred, in which case the liquid droplets contained in the secondary steam are more likely to drop downward due to gravity. At the position where the horizontal air inlet pipe 2 and the air inlet pipe 6 are connected, the air inlet pipe 6 continues to extend axially or extends below the horizontal air inlet pipe to form a liquid accumulation tank 4. The mechanism after extension or extension is not specifically limited, and a pipe is preferably provided. The horizontal air inlet pipe 2 is connected vertically or at an angle with the pipe, and the three-way structure design is preferred. The part above the horizontal air inlet pipe 2 is the air inlet pipe 6, and the part below the horizontal air inlet pipe 2 is closed at the mouth and is the liquid accumulation tank 4. This design changes the outlet position of the condensate water in the secondary steam, and changes the problem that the existing technology has a slow drainage speed of the relatively thin (generally 1-inch pipe) drain pipe 3, which is prone to water accumulation at the bottom of the horizontal air inlet pipe 2. In this design, the air inlet pipe 6 is generally selected to have a pipe diameter of 18 inches or 20 inches, of course, not limited to the above size settings. The greatly reduced gas-liquid carrying can further reduce the impact of liquid on the compressor blades, improving stability.
[0021] In an embodiment, a liquid blocking net 8 is arranged in the pipeline at the joint of the horizontal air inlet pipe 2 and the air inlet pipe 6, and the specific position is not limited as long as the secondary steam is at the position to enter the horizontal air inlet pipe 2, and the arrangement direction is not limited, which can be horizontal, vertical, or inclined, and the specific position is determined according to the arrangement position, and of course, the arrangement direction can also be inclined, and in the embodiment, the arrangement direction is preferably inclined at an angle of 45 degrees, and the specific position is shown in Figure 2 The aperture of the liquid blocking net 8 is not limited.
[0022] In an embodiment, a liquid blocking structure 9 is arranged in the pipeline of the extended part of the air inlet pipe 6, and the structure of the liquid blocking structure 9 is not limited, which can be a net-shaped body or a plate-shaped body with openings for liquid falling, and the shape is not limited, and in the embodiment, the liquid blocking structure 9 is a flared structure, as shown in Figure 2 .
[0023] In an embodiment, a liquid accumulation pump 5 connected with the liquid accumulation tank 4 is further included, and the liquid accumulation pump 5 is used to pump away the accumulated water in the liquid accumulation tank 4 for use in other places. The operation of the liquid accumulation pump 9 can be controlled by a timer, a float limiting starting device, an observation window, and the like, and the details are not described one by one.
[0024] Embodiment 2
[0025] As shown in Figure 3 , the embodiment discloses a steam pipeline device, which is a deformation based on the embodiment 2, and the specific position is as follows: at the joint of the horizontal air inlet pipe 2 and the air inlet pipe 6, the air inlet pipe 6 is connected with the liquid accumulation tank 4 through a connecting pipe 7 arranged below the horizontal air inlet pipe 2. Specifically, the air inlet pipe 6, the horizontal air inlet pipe 2, and the connecting pipe 7 form a tee structure, and the structure of the connecting pipe 7 is not limited, which can be a regular-shaped pipe or an irregular-shaped pipe, and in the embodiment, the connecting pipe 7 is a funnel-shaped structure. The liquid blocking structure 9 is arranged in the connecting pipe 7, and the structure of the liquid blocking structure 9 is not limited, which can be a net-shaped body or a plate-shaped body with openings for liquid falling, and the shape is not limited, and in the embodiment, the liquid blocking structure 9 is a flared structure, as shown in Figure 3 .
[0026] It should be noted that the connecting pipe 7 can also be an inlet pipe of the liquid accumulation tank 4, which is directly connected with the air inlet pipe 6. At this time, the connecting pipe 7 can be regarded as
[0027] The use process of the utility model is as follows:
[0028] When the secondary steam flows down along the inlet pipe 6, the liquefied liquid enters the liquid tank 4 or the connecting pipe 7 under the action of gravity, and the secondary steam with most of the liquid removed enters the steam mechanical compressor 1 along the horizontal inlet pipe 2 for compression.
