Description

Technical Field

[0001] This utility model belongs to the field of evaporation equipment technology, specifically relating to a high-efficiency anti-clogging falling film evaporation device. Background Technology

[0002] High-efficiency, anti-clogging falling film evaporators are a type of evaporation equipment used in various industrial fields, primarily for processes such as liquid concentration and evaporation. Falling film evaporation technology accelerates the evaporation process by forming a uniform liquid film on the heating surface, enabling more efficient heat exchange.

[0003] While existing technologies use falling film evaporators to concentrate and evaporate liquids, the condensate produced during the evaporation process generates scale over time, causing equipment blockage and resulting in reduced evaporation efficiency. Therefore, those skilled in the art have provided a high-efficiency, anti-clogging falling film evaporator to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a simple and rationally designed high-efficiency anti-clogging falling film evaporation device to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A high-efficiency, anti-clogging falling film evaporator includes a feed pipe with a liquid inlet fixedly connected to the middle of the top of the feed pipe, an evaporation device at the bottom of the feed pipe, the evaporation device including an evaporation mechanism and a filtration mechanism, a flow guiding device inside the evaporation device, a collection tank at the bottom of the evaporation device, an exhaust port fixedly connected to the side wall of the collection tank, and a concentrate outlet fixedly connected to the middle of the bottom of the collection tank.

[0007] As a further optimization of this utility model, the evaporation mechanism includes an evaporation tube fixedly connected to the bottom end of the feed pipe, a steam inlet fixedly connected to the upper side wall of the evaporation tube, a condensation outlet fixedly connected to the lower side wall of the evaporation tube, and a first flange fixedly connected to one end of the condensation outlet.

[0008] As a further optimization of this utility model, the filtration mechanism includes a filter tube fixedly connected to one end of the condensate outlet, a second flange fixedly connected to one end of the filter tube, a plurality of fixing bolts provided on the sidewalls of the second flange and the first flange, a drain port fixedly connected to the sidewall of the filter tube, a filter cylinder fixedly connected to the inner wall of the filter tube, a sealing ring fixedly connected to one end of the filter cylinder, and a rinsing mechanism provided on the sidewall of the filter tube.

[0009] As a further optimization of this utility model, the rinsing mechanism includes a partition plate rotatably connected to the inner wall of the filter cartridge, a damping rod fixedly connected to the top of the partition plate, the top of the damping rod rotatably passing through the inner wall of the filter cartridge and the inner wall of the filter tube and fixedly connected to a handle, a waste discharge port fixedly connected to the lower part of the side wall of the filter tube, and the top of the waste discharge port fixedly passing through the side wall of the filter tube and communicating with the inside of the filter cartridge, and a solenoid valve fixedly connected to the side wall of the waste discharge port.

[0010] As a further optimization of this utility model, the flow guiding device includes a fixed plate fixedly connected to the top and bottom of the evaporation tube, a flow divider fixedly connected to the middle of the top of the fixed plate located at the top of the evaporation tube, and a plurality of flow guiding mechanisms arranged between the two fixed plates.

[0011] As a further optimization of this utility model, the flow guiding mechanism includes a flow guiding pipe fixedly connected to two fixed plates. A spiral flow guiding plate is fixedly connected to the inner wall of the flow guiding pipe. One end of the flow guiding pipe is fixedly connected to the fixed plate at the top of the evaporation pipe and communicates with the inside of the feed pipe. The other end of the flow guiding pipe is fixedly connected to the fixed plate at the bottom of the evaporation pipe and communicates with the inside of the collection tank.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up an evaporation device, the liquid enters the feed pipe through the liquid inlet, and high-temperature steam is introduced into the evaporation pipe through the steam inlet. After the high-temperature steam comes into contact with the guide pipe, it can evaporate the liquid in the guide pipe. After the high-temperature steam evaporates, it is condensed and discharged through the condensation outlet. The condensate is filtered through the filter cartridge and discharged through the filter pipe, effectively filtering out impurities such as scale in the filter cartridge and effectively improving the service life of the equipment.

[0014] 2. In this utility model, by setting up an evaporation device, a flow divider is set on the fixed plate. After the liquid falls onto the flow divider, it first impacts the flow divider. At this time, the flow divider divides the liquid, which can make the liquid enter the guide tube evenly. A spiral guide plate is set in the guide tube. The spiral guide plate increases the movement path of the liquid and improves the evaporation efficiency of the liquid.

[0015] 3. In this utility model, after the filter tube has been working for a period of time, rotating the handle causes the baffle to block the filter cartridge, which can divide the filter cartridge into two areas. Condensate enters between the filter tube and the filter cartridge through the front end area of ​​the filter cartridge, and re-enters the filter cartridge through the rear end area of ​​the filter cartridge. At this time, opening the solenoid valve can discharge the dirt adhering to the inner wall of the filter cartridge, thereby achieving the purpose of reverse flushing of the equipment and effectively improving the service life of the equipment.

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example 1

[0025] like Figure 1 , Figure 2 As shown, a high-efficiency anti-clogging falling film evaporator includes a feed pipe 3, with a liquid inlet 4 fixedly connected to the middle of the top of the feed pipe 3, and an evaporation device 1 installed at the bottom of the feed pipe 3. The feed liquid is evaporated and concentrated by using the evaporation device 1. A flow guiding device 2 is installed inside the evaporation device 1 to increase the movement path of the feed liquid and improve the evaporation efficiency. A collection tank 5 is installed at the bottom of the evaporation device 1, with an exhaust port 6 fixedly connected to the side wall of the collection tank 5, and a concentrate outlet 7 fixedly connected to the middle of the bottom of the collection tank 5.

[0026] like Figure 3 , Figure 4As shown, a fixing plate 202 is fixedly connected to the top and bottom of the evaporation tube 101. A flow divider 203 is fixedly connected to the middle of the top of the fixing plate 202 at the top of the evaporation tube 101. The flow divider 203 is provided on the fixing plate 202. After the liquid falls onto the flow divider 203, it first impacts the flow divider 203. At this time, the liquid is divided by the flow divider 203, so that the liquid can enter the guide tube 204 evenly.

[0027] like Figure 3 , Figure 4 As shown, two fixed plates 202 are fixedly connected to a guide pipe 204. A spiral guide plate 201 is fixedly connected to the inner wall of the guide pipe 204. The spiral guide plate 201 has a spiral structure, which makes the liquid flow spirally along the guide pipe 204, increasing the contact area between the liquid and the heating surface and improving the heat transfer efficiency. One end of the guide pipe 204 is fixedly connected to the fixed plate 202 that penetrates the top of the evaporation pipe 101 and communicates with the inside of the feed pipe 3. The other end of the guide pipe 204 is fixedly connected to the fixed plate 202 that penetrates the bottom of the evaporation pipe 101 and communicates with the inside of the collection tank 5. The spiral guide plate 201 is provided in the guide pipe 204. The spiral guide plate 201 increases the movement path of the liquid and improves the evaporation efficiency of the liquid. After evaporation, the gas is discharged through the exhaust port 6 and the concentrate is discharged through the concentrate outlet 7.

[0028] like Figure 1 , Figure 2 As shown, an evaporator 101 is fixedly connected to the bottom of the feed pipe 3. A steam inlet 102 is fixedly connected to the upper side wall of the evaporator 101. The steam inlet 102 is a diversion pipe structure, which can improve the uniformity of contact between the steam and the guide pipe 204 after the steam enters, thereby improving the evaporation efficiency. A condenser outlet 103 is fixedly connected to the lower side wall of the evaporator 101. A first flange 109 is fixedly connected to one end of the condenser outlet 103. The liquid enters the feed pipe 3 through the liquid inlet 4. High-temperature steam is introduced into the evaporator 101 through the steam inlet 102. After the high-temperature steam contacts the guide pipe 204, it can evaporate the liquid in the guide pipe 204.

[0029] like Figure 5 , Figure 6As shown, a filter tube 105 is fixedly connected to one end of the condensate outlet 103, and a second flange 110 is fixedly connected to one end of the filter tube 105. Several fixing bolts 104 are provided on the side walls of the second flange 110 and the first flange 109. A drain port 106 is fixedly connected to the side wall of the filter tube 105. A filter cartridge 115 is fixedly connected to the inner wall of the filter tube 105. There is a gap between the filter cartridge 115 and the filter tube 105 to ensure that the condensate can rinse the filter cartridge 115. A sealing ring 112 is fixedly connected to one end of the filter cartridge 115. The outer diameter of the sealing ring 112 is equal to the inner diameter of the filter tube 105. The inner diameter of the sealing ring 112 is equal to the outer diameter of the filter cartridge 115. After the high-temperature steam evaporates, it is condensed and discharged through the condensate outlet 103. The condensate is filtered through the filter cartridge 115 and then discharged through the filter tube 105, effectively filtering out impurities such as scale in the filter cartridge 115 and effectively improving the service life of the equipment.

[0030] like Figure 5 , Figure 6 As shown, a baffle 111 is rotatably connected to the inner wall of the filter cartridge 115. A damping rod 113 is fixedly connected to the top of the baffle 111. The damping rod 113 ensures that the baffle will not shift due to the scouring of condensate after its position is fixed. The top of the damping rod 113 rotatably passes through the inner wall of the filter cartridge 115 and the inner wall of the filter tube 105 and is fixedly connected to a handle 114. A waste outlet 108 is fixedly connected to the lower part of the side wall of the filter tube 105, and the top of the waste outlet 108 is fixedly connected to the inside of the filter cartridge 115 through the side wall of the filter tube 105. A solenoid valve 107 is fixedly connected to the side wall of the waste outlet 108. After the filter tube 105 has been working for a period of time, rotating the handle 114 causes the partition 111 to block the filter cartridge 115, which can divide the filter cartridge 115 into two areas. Condensate enters the area between the filter tube 105 and the filter cartridge 115 through the front area of ​​the filter cartridge 115, and re-enters the filter cartridge 115 through the rear area of ​​the filter cartridge 115. At this time, opening the solenoid valve 107 can discharge the dirt adhering to the inner wall of the filter cartridge 115 to achieve the purpose of reverse flushing of the equipment.

[0031] It should be noted that in this high-efficiency anti-clogging falling film evaporator, the liquid enters the feed pipe 3 through the liquid inlet 4 during use. High-temperature steam is introduced into the evaporation pipe 101 through the steam inlet 102. After the high-temperature steam comes into contact with the guide pipe 204, it can evaporate the liquid in the guide pipe 204. After the high-temperature steam evaporates, it is condensed and discharged through the condensation outlet 103. The condensate is filtered through the filter cartridge 115 and discharged through the filter pipe 105. A flow divider 203 is set on the fixed plate 202. After the liquid falls onto the flow divider 203, it first impacts the flow divider 203. At this time, the flow divider 203 divides the liquid, which can make the liquid enter the guide pipe 204 evenly. A spiral guide plate 201 is set in the guide pipe 204. The spiral guide plate 201 increases the movement path of the liquid. After evaporation, the gas is discharged through the exhaust port 6, and the concentrate is discharged through the concentrate outlet 7.

[0032] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
