Description

Technical Field

[0001] This utility model relates to the field of spray towers, and more specifically, it relates to a spray tower packing replacement structure. Background Technology

[0002] A spray tower is a common gas treatment device, mainly used for gas purification and gas-liquid mass transfer processes. It removes pollutants, cools the gas, or facilitates chemical reactions by spraying liquid into the gas, ensuring full contact between the gas and liquid.

[0003] A spray tower consists of a tower body, a spray system, a packing layer, and a liquid circulation system. Gas enters from the bottom of the tower, is treated by the packing layer and the spray liquid system, and is discharged from the top of the tower. The spray system is used to evenly spray the liquid into the tower, while the packing layer is used to increase the gas-liquid contact area, so that the gas can have sufficient contact with the liquid, thereby improving the efficiency of pollutant absorption or reaction.

[0004] In spray towers, the number of packing layers is generally multiple, arranged from top to bottom along the height of the tower. Gas passes through multiple packing layers from bottom to top before being discharged from the top of the tower. After the gas is sprayed, the particles in the gas will be retained in the packing layers. When a large number of particles are accumulated in the packing layers, the packing layers need to be replaced. The packing layer at the bottom of the tower is usually replaced most frequently because the concentration of particles in the gas is the highest when the gas passes through the bottom packing layer, so the most particles are retained in the bottom packing layer. Existing towers generally have multiple material replacement ports. By taking out the old packing from the material replacement port and pouring in the new packing, a new packing layer is formed. However, the old packing is relatively scattered, and the cross-sectional area of ​​the tower is relatively large, resulting in low efficiency in taking out the old packing and hindering the speed of replacing the lower packing layers.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a spray tower packing replacement structure.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a spray tower packing replacement structure, comprising a tower body, wherein a plurality of support plates are provided inside the tower body, and a packing layer is provided on the support plates. A plurality of material replacement ports are opened on the outer wall of the tower body. The support plate at the bottom of the tower body is a lower support plate, and the material replacement port at the bottom of the tower body is a discharge port. The packing layer on the lower support plate is composed of a plurality of packing blocks. A plurality of partition plates are fixedly connected to the lower support plate, and a packing cavity is formed between two adjacent partition plates. The packing blocks are located in the packing cavity. A through hole communicating only with the packing cavity is opened on the bottom surface of the lower support plate. An annular groove is opened on the inner peripheral wall of the tower body. The outer edge of the lower support plate is rotatably connected to the annular groove. A limiting member is provided on the lower support plate. The limiting member restricts the movement of the packing blocks in the packing cavity by abutting against the outer peripheral wall of the packing blocks.

[0008] The present invention is further configured such that: a groove is provided on the lower support plate between the two partition plates, and a rotating hole is provided on each of the two inner walls opposite to the groove; the two ends of the limiting member are respectively embedded in the two rotating holes; an elastic member is sleeved on the limiting member; and the elastic member provides the limiting member with a force to rotate toward the packing block.

[0009] The present invention is further configured such that: a protrusion is provided on the outer peripheral wall of the filler block, and the top wall of the protrusion is used to abut against the limiting member.

[0010] The present invention is further configured such that: the groove is connected to the outer peripheral wall of the lower support plate; the limiting member includes two support rods and one abutting rod; the two ends of the abutting rod are respectively connected to the two support rods; the end of the support rod facing away from the abutting rod is rotatably connected to the rotating hole; and the abutting rod can be flipped into the feed port.

[0011] The present invention is further configured such that a support platform located below the discharge port is fixedly connected to the outer peripheral wall of the tower body.

[0012] The present invention is further configured such that the discharge port and the other material exchange ports are offset in the circumferential direction of the tower body.

[0013] In summary, this utility model has the following beneficial effects:

[0014] The packing block is a single piece, and no packing residue will remain on the lower support plate during the disassembly process. The aforementioned replacement structure makes the replacement of the packing layer faster and facilitates frequent replacement of the packing layer on the lower support plate. The timely replacement of the packing layer on the lower support plate can also reduce the frequency of replacement of the packing layer on other support plates. The replacement of the upper packing layer is often more dangerous and difficult than the lower layer. Reducing the frequency of replacement of the upper packing layer also makes it easier for people to replace the packing layer.

[0015] The limiting component restricts the movement of the packing block in the packing cavity by abutting against the outer peripheral wall of the packing block. The setting of the limiting component makes the packing block more stable in the packing cavity. Moreover, the position of the limiting component abutting against the packing block is on the outer peripheral wall of the packing block, which will not interfere with the top and bottom surfaces of the packing block, so that there is still enough area on the top and bottom sides of the packing block for gas to pass through.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] A spray tower packing replacement structure, such as Figure 1 , Figure 2 and Figure 3As shown, the structure includes a tower body with several support plates inside. A packing layer is installed on the support plates. Several material exchange ports 1 are located on the outer wall of the tower body. The support plate at the bottom of the tower body is a lower support plate 2, and the material exchange port 1 at the bottom of the tower body is a discharge port 3. The packing layer on the lower support plate 2 consists of several packing blocks 4. Several partition plates 5 are fixedly connected to the lower support plate 2, forming a packing cavity between adjacent partition plates 5. The packing blocks 4 are located in the packing cavity. A passageway communicating only with the packing cavity is opened on the bottom surface of the lower support plate 2. Hole 6; an annular groove 7 is formed on the inner circumferential wall of the tower body; the outer edge of the lower support plate 2 is rotatably connected to the annular groove 7; the packing block 4 is made of plastic and has several pores for gas to pass through. Gas flows into the pores from the bottom surface of the packing block 4 and then flows out from the top surface of the packing block 4. After the packing block 4 is inserted into the packing cavity through the discharge port 3, the lower support plate 2 is rotated so that another packing cavity is exposed in the discharge port 3, and then another packing block 4 is inserted, and so on, until all the packing blocks on the lower support plate 2 are in place. The cavity is filled with packing blocks 4, which are a single piece. During the disassembly of packing blocks 4, no packing residue remains on the lower support plate 2. The position of the through hole 6 avoids the partition plate 5, ensuring that the gas passing through the through hole 6 will definitely pass through the packing block 4. Through the above replacement structure, the packing layer replacement is faster and more convenient for frequent replacement of the packing layer on the lower support plate 2. The timely replacement of the packing layer on the lower support plate 2 can also reduce the frequency of replacement of the packing layer on other support plates. The replacement of the upper packing layer is often more dangerous and difficult than the lower layer. Reducing the frequency of replacement of the upper packing layer also facilitates the operation of replacing the packing layer. A support platform 12 is fixedly connected to the outer peripheral wall of the tower body, located below the discharge port 3. The setting of the support platform 12 makes it easy for people to reach the discharge port 3, ensuring the safety of people during replacement. The discharge port 3 is offset from other material replacement ports 1 in the circumferential direction of the tower body. A ladder is set on the tower body near other material replacement ports 1. The offset of the discharge port 3 from other material replacement ports 1 can reduce the interference of the ladder on the discharge port 3.

[0023] like Figure 2 and Figure 4As shown, the lower support plate 2 is provided with a limiting member. The limiting member restricts the movement of the packing block 4 in the packing cavity by abutting against the outer peripheral wall of the packing block 4. The setting of the limiting member makes the packing block 4 more stable in the packing cavity, and the position of the limiting member abutting against the packing block 4 is on the outer peripheral wall of the packing block 4, so as not to interfere with the top and bottom surfaces of the packing block 4, so that there is still enough area on the top and bottom sides of the packing block 4 for gas to pass through. A groove 8 is opened on the lower support plate 2 between the two partition plates. Rotating holes are opened on the two inner walls of the groove 8. The two ends of the limiting member are respectively embedded in the two rotating holes. An elastic member is sleeved on the limiting member. The limiting member provides a force to rotate toward the filling block 4. The elastic member is a torsion spring sleeved on the limiting member. The force applied to the limiting member by the elastic member causes the limiting member to rotate toward the filling block 4. The limiting member applies a resisting force to the filling block 4, so that the filling block 4 can remain in contact with the two partition plates 5, thus maintaining the stability of the filling block 4. The outer peripheral wall of the filling block 4 is provided with a protrusion 9. The top wall of the protrusion 9 is used to abut against the limiting member. While the limiting member abuts against the outer peripheral wall of the filling block 4, it also abuts against the top wall of the protrusion 9, thus applying a downward force to the filling block 4 and ensuring that the bottom wall of the filling block 4 is in contact with the lower support plate 2.

[0024] like Figure 4 As shown, the groove 8 is connected to the outer peripheral wall of the lower support plate 2. The limiting component includes two support rods 10 and one abutment rod 11. The two ends of the abutment rod 11 are respectively connected to the two support rods 10. The end of the support rod 10 facing away from the abutment rod 11 is rotatably connected in the rotating hole. The abutment rod 11 can be flipped into the feed port 3. The abutment rod 11 not only serves to abut against the filler block 4, but people can also fold the abutment rod 11 outward into the feed port to act as a handle.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
