Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of saturated steam transportation and relates to a steam-water separation device for saturated steam. Background Art
[0002] During the transportation of saturated steam in pipelines, due to temperature reduction and heat energy loss, part of the steam will condense into wet steam. Wet steam will reduce the production efficiency of equipment and the quality of products, and will also cause equipment damage. If the liquid droplets suspended in the steam cannot be effectively removed, they will condense in the steam-using equipment, affecting the operation of the equipment and even seriously affecting the service life of the steam-using equipment. Most of the existing shell boilers produce steam with a dryness of 95%-98%, and after the occurrence of steam-water priming in the boiler, more moisture will be carried. The water in the steam will bring quality problems to the products. Since water is a poor conductor of heat, the presence of water will reduce the production efficiency and product quality. Therefore, the utility model provides a steam-water separation device for saturated steam to solve the above technical defects. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a steam-water separation device for saturated steam to solve the problem that part of the wet steam is generated during the pipeline transportation of the existing saturated steam, which is likely to reduce the production efficiency of equipment and the quality of products.
[0004] To this end, the utility model adopts the following technical solutions:
[0005] A steam-water separation device for saturated steam includes a housing. A liquid baffle assembly is arranged inside the housing. A mist eliminator is arranged above the liquid baffle assembly, and a horizontally arranged air distribution pipe is arranged below the liquid baffle assembly. A condensate cavity is arranged below the air distribution pipe. A drain valve is arranged at the bottom of the housing, a steam inlet is arranged at the side part, and an air distribution pipe outlet is arranged at the top.
[0006] Further, the air distribution pipe is in a semi-circular ring shape, and a number of uniformly spaced air distribution holes are arranged at the top of the air distribution pipe. One end of the air distribution pipe is communicated with the steam inlet, and a steam outlet is arranged at the other end.
[0007] Further, the condensate cavity is arranged at the bottom of the housing.
[0008] Further, the liquid baffle assembly includes a number of vertically arranged channels. A number of inclined partitions are symmetrically arranged on the inner wall of the channels. The partitions on both sides of the inner wall of the channels are overlapped from bottom to top, and there is a gap between each partition. There is a gap between the bottom of the liquid baffle assembly and the housing.
[0009] Further, the mist eliminator is arranged in an inverted V shape and is provided with a mist catching wire mesh. Specifically, the mist catching wire mesh is made of polytetrafluoroethylene.
[0010] The beneficial effects of the present utility model are as follows:
[0011] By tangentially introducing saturated steam, the present utility model preliminarily separates some droplets in the steam by using centrifugal force while rotating the gas distribution. At the same time, a condensate chamber is provided to prevent the liquid from accumulating and flooding the gas distribution pipe due to untimely liquid drainage, thereby increasing the water content in the steam again.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The technical solutions of the present utility model will be described in detail below in conjunction with the drawings and the embodiments.
[0017] As Figure 1 shown, a steam - water separation device for saturated steam includes a housing 1. The housing 1 is in a vertical cylindrical shape, and its top and bottom are both made of arc - shaped plates, which is beneficial for liquid drainage and the discharge of dry steam. A drain valve 6 is provided at the bottom of the housing 1, a steam inlet 7 is provided on the side, and a steam outlet 8 is provided at the top. Among them, the drain valve 6 is arranged at the bottom of the housing 1, and the opening degree of the drain valve 6 is controlled according to the water content in the saturated steam, which can ensure that the condensate in the steam - water separation device can be discharged in time.
[0018] As Figure 2 shown, a liquid blocking assembly 4 is provided inside the housing 1. The liquid blocking assembly 4 includes a number of vertically arranged channels 4a. On the inner wall of the channels 4a, a number of inclined partition plates 4b are symmetrically provided. The partition plates 4b on both sides of the inner wall of the channels 4a are overlapped from bottom to top, and there is a gap between each partition plate 4b. There is a gap between the bottom of the liquid blocking assembly 4 and the housing 1, which is beneficial for the condensate collected above the partition plate 4b to be discharged along the inner wall of the channels 4a at the lowest point.
[0019] Above the liquid blocking assembly 4, a mist eliminator 5 is provided, and below it, a horizontally arranged gas distribution pipe 2 is provided.
[0020] AsFigure 3 As shown, the air distribution pipe 2 is semi-circular ring-shaped, and a number of air distribution holes 2a are provided at equal intervals at its top. One end of the air distribution pipe 2 is connected to the steam inlet 7, and the other end is provided with an air distribution pipe outlet 2b. The saturated steam tangentially enters the shell 1 through the air distribution pipe 2, and through the high-speed and spiral air intake method, a centrifugal motion is generated in the shell 1, and the initial part of the liquid droplets in the steam are thrown to the inner wall of the air distribution device by the generated centrifugal force, so as to achieve preliminary gas-liquid separation.
[0021] The mist eliminator 5 is arranged in an inverted V shape to facilitate increasing the mist-catching area in a limited space; the mist eliminator 5 is provided with a mist-catching wire mesh, and the mist-catching wire mesh is provided with a number of holes; specifically, the mist-catching wire mesh is made of polytetrafluoroethylene material.
[0022] A condensate chamber 3 is provided below the air distribution pipe 2. The condensate chamber 3 is arranged at the bottom of the shell 1. Its purpose is that when there is more moisture in the steam, the drain valve is not opened in time, or the opening degree of the drain valve is small, the condensed liquid can be temporarily stored in the condensate chamber 3 without flooding the air distribution pipe 2, otherwise it is easy to cause additional moisture in the steam after steam distribution.
[0023] The use process of the present utility model is as follows:
[0024] After the saturated steam is evenly distributed in the shell 1 through the air distribution pipe 2 and moves upward to the liquid baffle assembly 4, when the liquid droplets it carries pass through the partition plate 4b, through the form of baffle flow, the large condensed liquid droplets flow downward to the condensate chamber 3 by gravity. At this time, most of the moisture in the saturated steam can be condensed and separated this time, and a small part of the liquid droplets with smaller particle sizes move further upward with the steam flow to the mist eliminator 5. The steam velocity can be controlled by changing the diameter of the shell 1, and it is required that the saturated steam velocity is not less than 40 m / s, so that the wet steam makes a high-speed collision motion here. The remaining small mist droplets in the steam collide and condense in the mist-catching wire mesh, gather along the lower edge of the mist-catching wire mesh to the inner wall of the shell 1, and flow downward along the inner wall to the condensate chamber 3 under the action of gravity.
