Description

Technical Field

[0001] The invention relates to the field of steam-water separators, in particular to a baffle-type steam-water separator with multiple modules. Background Art

[0002] The baffle type steam-water separator is a common drying equipment used to separate suspended droplets in steam. Currently, most of the baffle type steam-water separators on the market are vertical. The principle is to introduce steam radially in the lower middle part of the tank body. A baffle is placed in the tank body. The steam blows on the baffle, and the gas partially bypasses the baffle. The suspended droplets with a larger specific gravity are difficult to collide and adhere to the baffle as the gas suddenly changes direction due to their larger inertia of movement. After accumulating to a certain extent, they flow downward to the bottom of the tank and are discharged. Its structural feature is that there is a main baffle facing the air inlet, and several auxiliary sub-baffles. When the steam blows vertically through the main baffle, its flow rate will rapidly decrease in the tank body with a larger diameter than the air inlet pipe. The remaining suspended droplets lose a lot of kinetic energy. When the steam bypasses the sub-baffle, the steam-water separation effect will gradually weaken.

[0003] The baffle type steam-water separator has good compatibility with the input speed of steam and can dry steam flow in a wide range of flow rates. However, its structural characteristics also give it obvious disadvantages. For example, the resistance of steam flow through the baffle type steam-water separator is large, which increases the pressure of the steam supply equipment. In addition, after the steam flow contacts and refracts with the main baffle, the flow rate loss is large and the separation efficiency gradually weakens.

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Example 1, reference Figure 1 and Figure 2, is the first embodiment of the present invention, which provides a baffle-type steam-water separator with a multi-section module, which reduces the flow resistance of steam through the steam-water separator and reduces the energy loss in the steam-water separation process. It includes a tank body 100, the tank body 100 is in a round tube shape, and end covers 101 are arranged at both ends of the tank body 100. The tank body 100 is arranged horizontally, and the end cover 101 is flange-connected to the tank body 100, and the end cover 101 is located at the bottom and is provided with a second interface 101b, and the end cover 101 is provided with a first interface 10 1a, and a modular steam-water separation mechanism 200 for steam-water separation is arranged between the first interface 101a in the tank body 100; the modular steam-water separation mechanism 200 includes a spoiler drum 201, the spoiler drum 201 is in a frustum shape, and the spoiler drum 201 is coaxial with the tank body 100, the small diameter end of the spoiler drum 201 is threadedly connected with the large diameter end of the adjacent spoiler drum 201, a connecting rod 202 is connected between the spoiler drum 201 and the tank body 100, and the edge of the large diameter end of the spoiler drum 201 is set in a circular arc.

[0027] Combined with the existing technology, the operating principle and advantages of the device are further explained: the existing vertical baffle steam-water separator is divided into two parts by a vertical partition, and the inlet and exhaust pipes are distributed on both sides of the partition. The steam entering the separator first impacts the partition to achieve preliminary steam-water separation, and then bypasses the partition upward under the restriction of the partition and is discharged from the exhaust port. In the process of bypassing the partition, the guiding effect of the partition makes the steam flow go through multiple small baffles to continue to change the direction of the steam flow, thereby improving the steam-water separation effect. Although the structure can achieve steam-water separation within a wider range of steam input speeds after iterative optimization, the main structural characteristics have been retained. The most significant problem of this type of structure is That is, the resistance of steam flow bypassing the main baffle is relatively large, which will cause the steam flow rate in the equipment to decrease rapidly, resulting in a higher steam-water separation efficiency in the initial stage. In the later stage, the steam-water separation effect becomes significantly worse due to the significant reduction in steam flow rate. The main reason for the high steam flow resistance is that the baffle-type steam-water separator needs to change the direction of the steam flow through the baffle refraction. However, the baffle size in the conventional vertical baffle steam-water separator is large, which causes higher resistance when bypassing the main baffle. In addition, when the steam flow bypasses the main baffle and each small baffle, the pressure difference between the front and back of the baffle will cause vortices to be generated, and the vortices not only do not help steam-water separation, but also consume the energy of the steam flow and slow down the flow rate of the steam flow.

[0028] Back to the device provided by the present invention, the device mainly proposes a new horizontal baffle steam-water separator. Although the device is still based on the principle of refracting steam flow to achieve steam-water separation in the traditional baffle steam-water separator, the structure is almost different. The difference is that the reference Figure 2The steam flow is introduced by the end cover 101 at the large diameter end of the modular steam-water separation mechanism 200 and flows to the other end located at the guide cover 204. The steam flow will first impact the drum surface of the first spoiler drum 201 it contacts, undergo the first refraction and achieve the first wave of steam-water separation. Then, under the limited space of the tank body 100, the steam flow bypasses the edge of the spoiler drum 201, flows to the next spoiler drum 201 and impacts the drum surface again, refracts to complete the second wave of steam-water separation, and so on, until the steam flow flows out from the end cover 101 at the other end, and the droplets captured by the spoiler drum 201 converge downward by gravity and are discharged through the second interface 101b of the end cover 101 (a steam trap needs to be connected).

[0029] In the above overview of the working principle, the device also has the following technical details: First, the spoiler drums 201 are connected in series, and each spoiler drum 201 has a smooth edge, which smoothly transitions the end face of the spoiler drum 201 to the conical surface of its back. Through the wall attachment effect, part of the steam flow is also made to flow along the edge of the spoiler drum 201, which can reduce the resistance of the steam flow bypassing the edge of the spoiler drum 201, and the droplets with larger specific gravity will fly out radially along the end face of the spoiler drum 201, thereby improving the steam-water separation effect. The steam flow that does not enter the wall attachment effect will radially impact the inner wall of the tank body 100 along the end face of the spoiler drum 201, thereby realizing the refraction of the steam flow again and improving the steam-water separation effect. Unlike the traditional baffle steam-water separator, the end face of the spoiler drum 201 is circular, and its edge is performing this steam-water separation at 360 degrees, thereby significantly improving the steam-water separation efficiency. Please refer to Example 2 for details.

[0030] Secondly, a beam ring 203 is also provided in the tank body 100, and the beam ring 203 is used to gather the steam flow that bypasses the edge of the spoiler drum 201 and escapes to the outside again, so that the steam flow that bypasses the edge of the spoiler drum 201 is concentrated to flow to the next section of the spoiler drum 201, which simply and effectively improves the steam-water separation efficiency. Please refer to Example 2 for details.

[0031] Thirdly, a flow guide hood 204 is further provided in the tank body 100, and the flow guide hood 204 can guide the steam flow and cooperate with the end cover 101 to provide a steam-water separation action again on the basis of the modular steam-water separation mechanism 200, which can effectively improve the steam-water separation efficiency of the equipment. Please refer to Example 3 for details.

[0032] In summary, the device is connected in series through the frustum-shaped spoiler drum 201 with rounded edges, and cooperates with the tank body 100, the beam ring 203 and the guide cover 204, so that the steam flow can flow rapidly and refract multiple times and over a large range in the tank body 100, thereby reducing the flow resistance of steam through the steam-water separator, reducing the energy loss in the steam-water separation process, and improving the steam-water separation efficiency, and effectively solving the problems of large steam flow resistance and large steam flow energy loss in the baffle-type steam-water separator.

[0033] Example 2, reference Figure 2~Figure 5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a modular steam-water separation mechanism 200 of a baffle-type steam-water separator with multiple modules, which enables the steam-water separation equipment to flexibly adjust the specifications and dimensions, greatly facilitates the specification design, production and commissioning of the equipment, and provides a continuous and stable steam-water separation effect, which includes: the spoiler drum 201 is a thin-walled hollow structure, the spoiler drum 201 is filled with a foaming material 206, and the spoiler drum 201 is filled with a foaming material 206. The two ends of the two sleeves 201a are connected to the inner wall of the spoiler drum 201 along the radial direction of the spoiler drum 201, and the connecting rod 202 passes through the sleeve 201a to penetrate the spoiler drum 201. The small diameter end of the spoiler drum 201 is provided with a stud 201b protruding along its axial direction, and the large diameter end of the spoiler drum 201 is provided with a screw mouth 201c concave along its axial direction, and the stud 201b and the screw mouth 201c are threadedly matched with each other. The cross section of the beam ring 203 is The contour is V-shaped, and the outer ring wall of the beam ring 203 is annular and fits with the inner wall of the tank body 100. The inner ring wall of the beam ring 203 is conical, and its cone angle is consistent with the cone angle of the spoiler drum 201. The beam ring 203 is located close to the end of the large diameter of the spoiler drum 201. A screw 207 is connected between the outer ring wall of the beam ring 203 and the side wall of the tank body 100, and one end of the connecting rod 202 passes through the side wall of the tank body 100 and is threadedly connected with a nut 208. The screw 20 7. A pad 209 is provided between the nut 208 and the outer wall of the tank body 100, and the pad is provided with a circular arc surface to fit the outer wall of the tank body 100, the spoiler drum 201 is provided with a circular groove 201d at the screw mouth 201c, and a threaded plug 205 is provided in the tank body 100, the threaded plug 205 is threadedly connected with the screw mouth 201c, and the head of the threaded plug 205 is sleeved with the circular groove 201d, and the head end face of the threaded plug 205 is coplanar with the end face of the large diameter end of the spoiler drum 201.

[0034] refer to Figure 5The core of the modular steam-water separation mechanism 200 is the spoiler drum 201. The main body of the spoiler drum 201 is made of half shells manufactured by stamping and stretching process and then spliced ​​and welded. It has the advantages of light weight, low material consumption, low cost and easy availability. Of course, before welding and closing its shell, it is necessary to implant a sleeve 201a and fill it with foaming material 206. The role of the sleeve 201a is to be used for plugging the connecting rod 202, and then connecting the tank body 100 through the connecting rod 202. The cross-shaped sleeve 201a makes it possible for the spoiler drum 201 to be in any direction after the connecting rod 202 is plugged in. The spoiler drum 201 is not restricted and can be stably fixed in the tank body 100. In addition, due to the smooth shape of the spoiler drum 201, the sleeve 201a and the connecting rod 202 also serve as a fixing tool. By extending the lever arm through the connecting rod 202, two adjacent spoiler drums 201 can be easily connected and tightened. The filling foam material 206 is an important link. In addition to providing internal support for the thin shell structure of the spoiler drum 201, it also serves as a damping material to prevent the steam flow from repeatedly refracting and impacting in the tank body 100 to cause resonance of the thin shell of the spoiler drum 201, thereby playing an important role in protecting the equipment.

[0035] In addition to being fully designed in terms of steam-water separation effect and production process considerations, the modular assembly design of the spoiler drum 201 also makes it very convenient to adjust the parameters and specifications of the entire equipment. Referring to the traditional vertical plate steam-water separator, products of different specifications have different volumes, requiring casting molds of different sizes and production debugging data of different parameters. The consequence is that if you want to cover markets with different demands, the adjustment and coverage of equipment parameters and specifications will become extremely inconvenient and costly.

[0036] The size of each spoiler drum 201 of the device is the same. When the performance needs to be enhanced, it is only necessary to stack more spoiler drums 201 and a matching number of beam rings 203. The tank body 100 can be made of round tubes of different lengths by simply opening holes in the side walls. The end cover 101 is also a universal part, which is extremely convenient in production.

[0037] The rest of the structure is the same as that of Example 1.

[0038] In summary, this mechanism enables the gas-water separation equipment to flexibly adjust its specifications and dimensions, greatly facilitates the specification design, production and commissioning of the equipment, and provides a continuous and stable gas-water separation effect.

[0039] Example 3, reference Figure 2 , Figure 4 and Figure 6, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a baffle-type steam-water separator with a multi-section module. The use of the baffle 204 can make full use of the end cover 101 to further separate steam and water, effectively improving the steam-water separation efficiency of the equipment or, relatively, can effectively reduce the volume of the equipment. It includes: the baffle 204 is in the shape of a short round tube, and the baffle 204 is connected to a transfer seat 204a, and the transfer seat 204a is connected to the transfer seat 204a. One end of the small diameter of the spoiler drum 201 is threadedly connected, one end of the deflector cover 204 is sealed and sleeved with the outer wall of the spoiler drum 201, and the other end of the deflector cover 204 is aligned with the opening of the end cover 101, the inner wall of the deflector cover 204 is connected with ribs 204b along its radial direction, and the ribs 204b are connected to the adapter seat 204a, and a through hole 204c is opened in a straight line between the adapter seat 204a and the deflector cover 204, and the through hole 204c is arranged along the radial direction of the deflector cover 204.

[0040] refer to Figure 2 At the installation position of the middle flow guide 204, the port of the flow guide 204 keeps a distance from the end cover 101, and the steam flow flowing through the modular steam-water separation mechanism 200 does not directly flow out from the first interface 101a of the end cover 101, but, under the guidance of the flow guide 204 and the tank body 100, launches the final impact to the inner end surface of the end cover 101, so that the steam flow is finally refracted and flows out from the space between the flow guide 204 and the end cover 101, making full use of the equipment structure to maximize the steam-water separation.

[0041] The rest of the structure is the same as that of Example 2.

[0042] In summary, the guide cover 204 effectively improves the steam-water separation efficiency of the equipment and, relatively speaking, can effectively reduce the volume of the equipment.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
