Description

Technical Field

[0001] The utility model belongs to the technical field of gas-liquid separation devices, and particularly relates to a steam separation device, which is used in the leaching workshop for large-scale vegetable oil production to purify the steam transported through pipelines to the plant area and separate the entrained small droplets. Background Technique

[0002] Steam is widely used in industrial production. In the industrial production process of edible oils, saturated steam is used as a heat source to heat materials to meet the process requirements. As the production units have higher and higher requirements for energy consumption assessment, how to reduce the steam consumption per ton and maximize the use of the heat of steam in the material conversion process without waste. The oil production units use commercial-grade steam, which is transported through pipelines to the steam distribution header in the plant area, and then transported to the workshop production equipment through branch pipelines. Due to various reasons, the transported steam is entrained with a small amount of droplets. If not removed, the droplets will adsorb on the surface of the subsequent heat exchange equipment to form a liquid film, increasing the heat transfer resistance. For a certain temperature that the corresponding equipment needs to reach, the steam volume needs to be increased; the formed water droplets will accelerate the surface corrosion of pipelines and equipment, reduce the service life of equipment, and increase the equipment investment of production units.

[0003] During the transportation process of steam, droplets and other impurities are entrained. To improve the utilization rate of steam and ensure the safety of subsequent used equipment, the steam is effectively separated. The existing technology cannot thoroughly separate the droplets and impurities in the steam, and the steam dryness cannot be effectively guaranteed. Content of the Utility Model

[0010] In order to solve the technical problem that part of the steam does not contact the liquid gathering component due to its small size, the utility model adopts the following technical solution: the four sides of the liquid gathering component extend to the outside of the outlet of the steam inlet to ensure the collision area between the steam and the liquid gathering component.

[0011] In order to further improve the technical problem of gas-liquid separation efficiency, the utility model adopts the following technical scheme: the number of the liquid collecting plates is 5, the height of the 5 liquid collecting plates is equal to 2 times the diameter of the steam inlet; the width of a single liquid collecting plate is equal to 2 times the diameter of the steam inlet, so as to fully ensure the collision area between the steam and the liquid collecting component.

[0016] at least two first baffles, the first baffles being arranged from top to bottom on the center plate on the steam inlet side;

[0017] The second baffle is arranged on the cylinder, and the second baffle is arranged alternately with the first baffle.

[0018] The baffle plates are arranged staggeredly. Every time the air flow passes through a baffle plate, its direction changes once.

[0035] The steam required for the production in the oil leaching workshop is generally purchased from the boiler factory and enters the oil plant area through the conveying pipeline. In order to make more efficient use of the heat energy of the steam and save the comprehensive steam consumption, it is necessary to process the steam, collect and recycle the liquid droplets entrained in the gas flow to obtain dry steam.

[0036] As Figure 1 shown, the steam separation device 10 includes a cylinder body 100.

[0037] An inlet 101 for steam is installed on one side of the cylinder body 100. The inlet 101 for steam extends into the first chamber 105. The inlet 101 for steam includes an inlet pipe. A connecting flange is installed at the outer end of the inlet pipe for connecting the steam supply equipment.

[0038] An outlet 102 for steam is installed on the other side of the cylinder body 100. The outlet 102 for steam and the inlet 101 for steam are located on both sides of the cylinder body 100. The outlet 102 for steam includes an outlet pipe. A connecting flange is installed at the outer end of the outlet pipe for connecting the steam using equipment. Preferably, the diameter of the outlet pipe is larger than that of the inlet pipe.

[0039] In one embodiment, the steam outlet 102 extends into the second chamber 106. In one embodiment, the inlet of the steam outlet 102 is inclined toward the bottom of the cylinder. The pipe of the steam outlet of the utility model is inserted into the inner cylinder, and an oblique cut is made at the bottom. During the movement of the airflow, the flow direction is changed, and the droplets continue to move downward under the action of gravity inertia, collide with the inner wall of the device, gather and flow out.

[0040] A drain port 103 is provided on the bottom end cap 109 of the cylinder 100. The drain port 103 includes a drain pipe, and the inlet of the drain pipe is flush with the bottom end cap. A connecting flange is installed at the outer end of the drain pipe for connecting to a drain collection device. The drain port at the lowest point collects the droplets captured on both sides of the first cavity and the second cavity, and can be discharged in time, thereby ensuring the dryness of the steam in the equipment.

[0041] An exhaust port 104 is provided on the top end cap of the cylinder 100. The exhaust port 104 includes an exhaust pipe, and the exhaust pipe inlet is flush with the top end cap. A connecting flange is installed at the outer end of the exhaust pipe for connecting to an exhaust gas collection device. An exhaust port is provided at the highest point of the equipment. When the plant is shut down, the port can be opened to discharge the internal steam to prevent the steam condensation from causing negative pressure in the equipment, which may cause damage to the equipment and pipelines.

[0042] A central plate 107 is disposed in the cylinder 100 , and the central plate 107 divides the inner part of the cylinder into a first chamber 105 and a second chamber 106 that are connected. A steam inlet 101 is installed in the first chamber 105 , and a steam outlet 102 is installed in the second chamber 106 .

[0043] like Figure 1 As shown, a liquid collecting assembly 110 is installed on the central plate 110. The liquid collecting assembly 110 is arranged opposite to the outlet of the steam inlet 101. The liquid collecting assembly 110 is used to capture liquid droplets in the steam delivered from the steam inlet to prevent the liquid droplets from rebounding into the airflow for a second time.

[0044] In one implementation, Figure 2 , 3 As shown, the liquid collecting assembly 120 includes a plurality of liquid collecting plates 121 spaced apart from each other from top to bottom. The shape of the liquid collecting plates 121 is preferably an inverted V shape.

[0045] In one implementation, the periphery of the liquid collecting assembly 120 extends to the outside of the outlet of the steam inlet 101 .

[0046] In one implementation, the number of the liquid collecting plates 121 is 5, and the height of the 5 liquid collecting plates is equal to twice the diameter of the steam inlet; the width of a single liquid collecting plate 121 is equal to twice the diameter of the steam inlet.

[0047] The utility model adopts a baffle structure, and the collision of droplets with the liquid collecting plate gathers together to form a liquid flow for discharge. The utility model is provided with 5 groups of liquid collecting plates on the central plate, and the covering height of the liquid collecting plates is equal to 2 times the diameter of the steam inlet pipe. The installation position is tilted downward, which can effectively capture droplets and prevent secondary rebound into the airflow. Small droplets gather together and flow downward under the action of gravity and are discharged through the liquid discharge port.

[0048] In one implementation, an anti-impact plate 112 is provided on the center plate 1 to prevent the steam delivered by the steam inlet from impacting the center plate. The liquid collecting assembly 110 is installed on the anti-impact plate 112 .

[0049] In one implementation, a baffle assembly 120 is provided on the central plate on the steam inlet side, the baffle assembly is located above the liquid collecting assembly, and the baffle assembly is used to increase the steam stroke and separate gas and liquid. Specifically, the baffle assembly 120 includes a first baffle 121 and a second baffle 122.

[0050] There are at least two first baffles 121. The first baffles 121 are arranged from top to bottom on the central plate 107 on the steam inlet side. Specifically, the first baffles are in an inverted V shape, which increases the contact area between the baffles and the steam and improves the vapor-liquid separation efficiency.

[0051] The second baffles 122 are welded on the inner wall of the first chamber 105, and the second baffles 122 are arranged alternately with the first baffles 121. Specifically, the second baffles are inverted V-shaped, which increases the contact area between the baffles and the steam and improves the vapor-liquid separation efficiency.

[0052] Preferably, the first baffle 121 and the second baffle 122 are arranged in an overlapping manner to solve the technical problem that part of the gas does not contact the baffle assembly and moves directly upward, so that the steam will inevitably contact the baffle assembly during the upward movement, further improving the gas-liquid separation efficiency.

[0053] In one embodiment, the first baffle 121 and the steam inlet 101 in the first chamber 105 are staggered to solve the technical problem that part of the gas moves directly upward without contacting the liquid collecting component, increase the proportion of steam at the steam inlet in contact with the liquid collecting component, and further improve the gas-liquid separation efficiency.

[0054] The utility model has three baffles arranged inside, one of which is welded to the inner cylinder, and two are welded to the center plate, and they are arranged in a staggered manner to force the gas to perform baffle motion, thereby changing the direction of gas flow and increasing the distance of gas flow, thereby increasing the chance of droplets colliding with the baffles.

[0055] The utility model places the center plate at the center of the equipment and divides the cylinder into two cavities, the first cavity and the second cavity. The center plate is welded to the inside of the cylinder. The airflow enters the first cavity through the steam inlet, is deflected under the action of the baffle assembly, passes over the center plate from the upper space to the second cavity, and then enters the downstream equipment through the exhaust port. A drainage port is provided at the center position of the lower head, i.e., the lowest point of the equipment. Liquid on both sides of the center plate gathers there and is quickly discharged through this port, and the internal liquid does not remain.

[0056] Working process of steam separation device:

[0057] Steam enters the equipment at a certain speed through the steam inlet and impacts the liquid collecting component. The liquid droplets are collected under the obstruction of the liquid collecting plate and flow to the lower part of the first cavity along the liquid collecting plate. The airflow continues to move upward.

[0058] Three groups of baffles are arranged in a staggered manner. Each time the airflow passes through a baffle, the direction changes. Under the action of inertia, the droplets collide with the baffles and the center plate. When the droplets gather to a certain volume, they fall into the lower area under the action of gravity.

[0059] The gas passes over the center plate in the upper area to the second cavity. The exhaust port is inserted into the cylinder and cut obliquely. The airflow flows from top to bottom in the second cavity, and turns back to enter the pipeline upward at the exhaust port. This changes the airflow direction and prevents the airflow from directly entering the exhaust pipe and carrying droplets out.

[0060] The droplets continue to move downward under the combined effect of their own weight and inertia, and are effectively separated and gathered in the lower area for discharge.
