An assembled high-strength pallet

Abstract

The present invention provides a new type of assembled high-strength pallet, comprising: a base plate, on which a plurality of air holes are provided; a reinforcing structure, which is provided on the base plate and protrudes outward relative to the base plate; and a fixing component, which is provided on at least one side of the pallet. The reinforcing structure protruding outward can improve the strength of the pallet itself, increase the surface area of ​​the pallet, increase the opening area, and improve the efficiency of smoke passage. The pallet with a reinforcing structure has an increased area for receiving spraying because the reinforcing structure protrudes relatively outward, and more spray liquid adheres to the pallet, thereby increasing the contact area and contact efficiency between the spray liquid and the smoke, thereby enhancing the effect of wet dust removal. The splicing between adjacent pallets is detachably connected through a fixing component, which improves the installation efficiency while not involving welding operations, thus avoiding the occurrence of fire and improving the safety of the desulfurization tower renovation project.

Description

Technical Field

[0001] The invention relates to the technical field of flue gas desulfurization and denitrification equipment structures, and in particular to an assembled high-strength new type pallet. Background Art

[0002] Thermal power plants produce a lot of flue gas during operation, and the flue gas contains pollutants such as sulfur, so there are strict emission standards for flue gas emissions from thermal power plants. With the gradual strengthening of environmental awareness, the emission requirements of thermal power plants are also getting higher and higher. The desulfurization tower is one of the flue gas treatment equipment in thermal power plants. With the innovation of technology, the desulfurization tower needs to be continuously modified so that the flue gas passing through the desulfurization tower can be more efficiently and harmlessly treated.

[0003] The tray is an important structure in the desulfurization tower. There are air holes on the tray. When the flue gas moves from bottom to top in the desulfurization tower, it is evenly divided into several strands through the air holes on the tray, so that the flue gas distribution in the desulfurization tower is more even, and the reaction degree is more uniform during the desulfurization reaction, which makes it easier to improve the desulfurization efficiency.

[0004] The desulfurization tower using wet desulfurization usually has a spray structure inside, and the tray is usually set below the spray structure. During the spraying process, the spray will fall on the tray, which requires the tray to have a certain strength. The existing tray structure generally includes a base steel plate, and the base steel plate is welded on the perforated plate. However, due to the large inner diameter of the desulfurization tower, it is necessary to first splice the base steel plate inside the desulfurization tower, and then perform welding operations inside the desulfurization tower. However, the inner wall of the desulfurization tower is usually attached with smoke and dust, and the high-temperature sputtering generated during the welding process is easy to cause a fire, which poses certain safety hazards. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect of the prior art that the pallet structure is welded and laid in the desulfurization tower, which poses a safety hazard, thereby providing a new type of assembled high-strength pallet.

[0006] A new type of assembled high-strength pallet, comprising:

[0007] A substrate, wherein a plurality of air holes are provided on the substrate;

[0008] A reinforcing structure, disposed on the base plate and protruding outward relative to the base plate;

[0009] The fixing assembly is arranged on at least one side of the tray.

[0010] The fixing assembly comprises:

[0011] A first fixing portion, at least provided on one side of the substrate, extending outward from the substrate;

[0012] The second fixing part is arranged on the base plate and has a notch which can be just embedded in the first fixing part.

[0013] The fixing component further comprises:

[0014] The protrusion is arranged on the first fixing part and protrudes relative to the first fixing part; and / or the protrusion is arranged on the second fixing part, and the protrusion is distributed on the inner side wall of the notch.

[0015] A guide groove is provided inside the notch of the second fixing portion.

[0016] The second fixing portion includes a first side wall and a second side wall, and the notch is formed between the first side wall and the second side wall.

[0017] The second fixing portion further includes:

[0018] A second inclined section connects the first side wall and the second side wall, and an angle between the second inclined section and the first side wall is an acute angle.

[0019] The first fixing portion is provided with a chamfer toward the angle.

[0020] The first fixing portion comprises:

[0021] A first inclined section is connected to the substrate, a surface of the first inclined section facing the second fixing portion is an inclined surface, and a gap is formed between the first inclined section and the second fixing portion.

[0022] There are at least two second fixing parts, a limiting gap is provided between two adjacent second fixing parts, and the length of the first fixing part does not exceed the width of the limiting gap.

[0023] The reinforcement structure comprises:

[0024] A first bending portion, connected to the substrate, wherein an angle α between the first bending portion and the substrate is an acute angle;

[0025] The second bending portion is arranged at an end of the first bending portion away from the substrate.

[0026] The technical solution of the present invention has the following advantages:

[0027] 1. The present invention provides a new type of assembled high-strength pallet, comprising: a base plate, on which a plurality of air holes are provided; a reinforcing structure, which is arranged on the base plate and protrudes outward relative to the base plate; and a fixing component, which is arranged on at least one side of the pallet.

[0028] The outwardly protruding reinforcement structure can not only improve the strength of the tray itself, but also increase the surface area of ​​the tray, increase the opening area, and improve the efficiency of flue gas passing. The tray is usually under the wet dust removal mechanism to perform flow equalization on the flue gas before the wet dust removal. The tray with a reinforced structure has a larger area for receiving spraying due to the relatively outward protrusion of the reinforced structure, and more spray liquid is attached to the tray, which increases the contact area and contact efficiency between the spray liquid and the flue gas, thereby enhancing the effect of wet dust removal. Due to the existence of the reinforced structure, while improving the strength of the tray, it can be hung in the desulfurization tower through the connection part. There is no need for a truss structure, and there is no need to lay the trays one by one and connect them to the truss. The strength increases due to the change in shape, thereby reducing the number of connection points on the tray. The splicing between adjacent trays is detachable through fixed components, which improves the installation efficiency while not involving welding operations, avoiding the occurrence of fire and improving the safety of the desulfurization tower renovation project.

[0029] 2. The new type of assembled high-strength pallet provided by the present invention further includes, based on the fixing component: a raised portion, which is arranged on the first fixing portion and protrudes relative to the first fixing portion; and / or the raised portion is arranged on the second fixing portion, and the raised portion is distributed on the inner side wall of the groove.

[0030] On the one hand, the raised portion can make the mating surfaces between the first fixed portion and the second fixed portion rougher. When the raised portion is an elastic part, it can be deformed under pressure when the first fixed portion and the second fixed portion cooperate with each other, thereby increasing the bonding strength between the first fixed portion and the second fixed portion. As an alternative embodiment, the raised portion is made of rubber material. Since the ambient temperature of the working part of the tray inside the desulfurization tower is around 50°C, the influence of the working environment on the raised portion made of rubber material can be ignored. As an alternative embodiment, the raised portion and the first fixed portion are integrally formed and are both made of steel.

[0031] 3. In the assembled high-strength novel pallet provided by the present invention, a guide groove is provided on the inner side of the notch of the second fixing portion.

[0032] The guide groove can be matched with the first fixing part, which can increase the contact area between the first fixing part and the second fixing part when they are matched, and improve the bonding strength between the two. On the other hand, when the first fixing part and the second fixing part are installed, the protrusion is embedded in the guide groove and slides along the guide groove, which can play a guiding role and improve the assembly efficiency of the tray.

[0033] 4. In the assembled high-strength new pallet provided by the present invention, the second fixing portion further includes: a second inclined section, the second inclined section connects the first side wall and the second side wall, and the angle between the second inclined section and the first side wall is an acute angle.

[0034] A U-shaped slot structure is formed by a first side wall, a second inclined section, and a second side wall. The guide slot is on at least one inner side of the slot structure, and the guide slot extends along the length direction of the entire slot. When the first fixing portion is inserted into the slot, the protrusion is inserted into the guide slot for sliding assembly. As an alternative embodiment, the second inclined section and the first side wall are perpendicular to each other. As another alternative embodiment, the angle between the second inclined section and the first side wall is an obtuse angle.

[0035] 5. The new type of assembled high-strength pallet provided by the present invention has at least two second fixing parts, and a limiting gap is provided between two adjacent second fixing parts, and the length of the first fixing part does not exceed the width of the limiting gap.

[0036] When installing the tray, the first fixing part can be inserted into the limited gap first, and then the first fixing part can be aligned with the notch position on the second fixing part, so that the first fixing part can be slid and embedded into the second fixing part for assembly. This can save the space occupied by the assembly between adjacent trays, and provide convenience for the staff when performing the installation operation in the desulfurization tower.

[0048] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] Example 1

[0050] The present invention provides a new type of assembled high-strength pallet, such as Figure 1 , Figure 2As shown, it includes: a substrate 1, on which a plurality of air holes 12 are provided; a reinforcing structure 11, which is arranged on the substrate 1 and protrudes outward relative to the substrate 1; and a fixing component, which is arranged on at least one side of the tray. The outwardly protruding reinforcing structure 11 can improve the strength of the tray itself, increase the surface area of ​​the tray, increase the opening area, and improve the efficiency of flue gas passing. The tray is usually under the wet dust removal mechanism, and the flue gas is subjected to flow equalization treatment before the flue gas is wet dust removed. The tray with the reinforcing structure 11, because the reinforcing structure 11 protrudes relatively outward, the area receiving the spray is increased, and more spray liquid is attached to the tray, which increases the contact area and contact efficiency between the spray liquid and the flue gas, thereby enhancing the effect of wet dust removal. Due to the existence of the reinforcing structure 11, while improving the strength of the tray, it can be hung in the desulfurization tower through the connecting part. There is no need for a truss structure, and there is no need to lay the trays one by one and connect them to the truss. The strength increases due to the shape change, thereby reducing the connection points on the tray. The adjacent pallets are connected by detachable fixed components, which improves the installation efficiency without involving welding operations, avoids the occurrence of fire, and improves the safety of the desulfurization tower renovation project.

[0051] There is no specific limitation on the forming method of the pallet. Based on the above embodiment, as a further limited embodiment, the pallet is formed by bending a whole steel plate. As an alternative embodiment, the steel plate can be formed by stamping to obtain the reinforcement structure 11. As another alternative embodiment, the pallet structure with the reinforcement structure 11 can be obtained by integrally molding through mold casting.

[0052] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 As shown, the fixing assembly includes: a first fixing portion 2, which is provided on at least one edge of the base plate 1 and extends outward from the base plate 1; and a second fixing portion 3, which is provided on the base plate 1 and has a notch that can just fit into the first fixing portion 2. The first fixing portion 2 of one pallet is aligned with the second fixing portion 3 of the other pallet, so that the first fixing portion 2 fits into the notch of the second fixing portion 3, thereby achieving the splicing of the two pallets.

[0053] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3As shown, the fixing assembly further includes: a protrusion 21, which is provided on the first fixing part 2 and is protruding relative to the first fixing part 2; and / or, the protrusion 21 is provided on the second fixing part 3, and the protrusion 21 is distributed on the inner side wall of the notch. On the one hand, the protrusion 21 can make the mating surfaces between the first fixing part 2 and the second fixing part 3 more rough. When the protrusion 21 is an elastic part, it can be deformed under pressure when the first fixing part 2 and the second fixing part 3 cooperate with each other, thereby increasing the bonding strength of the first fixing part 2 and the second fixing part 3. As an alternative embodiment, the protrusion 21 is made of rubber material. Since the ambient temperature of the tray in the working part inside the desulfurization tower is about 50°C, the influence of the working environment on the protrusion 21 made of rubber material can be ignored. As an alternative embodiment, the protrusion 21 is integrally formed with the first fixing part 2 and both are made of steel.

[0054] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 As shown, a guide groove 31 is provided inside the notch of the second fixing portion 3. The guide groove 31 can be matched with the first fixing portion 2, which can increase the contact area between the first fixing portion 2 and the second fixing portion 3 when they are matched, and improve the bonding strength between the two. On the other hand, when the first fixing portion 2 and the second fixing portion 3 are installed, the protrusion 21 is embedded in the guide groove 31 and slides along the guide groove 31, which can play a guiding role and improve the assembly efficiency of the tray.

[0055] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 As shown, the second fixing portion 3 includes a first side wall 33 and a second side wall 34 , and the notch is formed between the first side wall 33 and the second side wall 34 .

[0056] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 As shown, the second fixing portion 3 also includes: a second inclined section 32, the second inclined section 32 connects the first side wall 33 and the second side wall 34, and the angle between the second inclined section 32 and the first side wall 33 is an acute angle. A U-shaped notch structure is surrounded by the first side wall 33, the second inclined section 32, and the second side wall 34. The guide groove 31 is on at least one inner side of the notch structure, and the guide groove 31 extends along the length direction of the overall notch. When the first fixing portion 2 is inserted into the notch, the protrusion 21 is embedded in the guide groove 31 and slidably inserted and assembled. As an alternative embodiment, the second inclined section 32 and the first side wall 33 are perpendicular to each other. As another alternative embodiment, the angle between the second inclined section 32 and the first side wall 33 is an obtuse angle.

[0057] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 As shown, the first fixing part 2 is provided with a chamfer 211 toward the angle. A certain space is formed between the chamfer 211 and the angle structure, which reduces the dimensional accuracy of the first fixing part 2 and the second fixing part 3, making the first fixing part 2 and the second fixing part 3 easier to match.

[0058] On the basis of the above implementation manner, as a further limited implementation manner, Figure 3 As shown, the first fixing part 2 includes: a first inclined section 22, the first inclined section 22 is connected to the substrate 1, and the surface of the first inclined section 22 facing the second fixing part 3 is an inclined surface, and a gap is formed between the first inclined section 22 and the second fixing part 3. The upper and lower sides of the first fixing part 2 are respectively attached to the second side wall 34 and the first side wall 33, and the inclined first inclined section 22 can leave a gap between the first inclined section 22 when the first fixing part 2 is embedded in the second fixing part 3.

[0059] On the basis of the above implementation manner, as a further limited implementation manner, Figure 4 , Figure 5 As shown, there are at least two second fixing parts 3, and there is a limiting gap 4 between two adjacent second fixing parts 3. The length of the first fixing part 2 does not exceed the width of the limiting gap 4. When installing the tray, the first fixing part 2 can be inserted into the limiting gap 4 first, and then refer to Figure 5 Then align the first fixing part 2 with the notch position on the second fixing part 3 in the direction of the middle arrow, so that the first fixing part 2 can be slid and embedded into the second fixing part 3 for assembly. This can save the space span between adjacent pallets during assembly, providing convenience for the staff when performing the assembly operation in the desulfurization tower.

[0060] On the basis of the above implementation manner, as a further limited implementation manner, Figure 1 , Figure 2As shown, the reinforcing structure 11 includes: a first bending portion 111, which is connected to the substrate 1 and the angle α between the first bending portion 111 and the substrate 1 is an acute angle; a second bending portion 112, which is arranged at one end of the first bending portion 111 away from the substrate 1. The first bending portion 111 is arranged at an acute angle with the substrate 1 as a whole, so that the surface of the first bending portion 111 is inclined toward the wet dust removal mechanism. The spray liquid falls on the surface of the inclined first bending portion 111, which plays a guiding role and guides the spray liquid to spread evenly on the surface of the air flow distribution plate. During the diffusion process of the spray liquid, it passes through the air vents 12, which makes it easier to form a thin film. Since the spray liquid is continuously sprayed, the spray liquid used to form the thin film flows continuously along the surface of the air flow distribution plate, thereby preventing the air vents 12 from being directly sprayed and damaging the thin film. When the film is broken, a violent air flow will be formed locally, which can improve the contact and mixing of the smoke and the spray liquid on the one hand, and on the other hand, the broken film breaks the spray liquid that originally constitutes the film into small droplets, so that it can be fully diffused in the smoke. On the other hand, since the inclined first bending portion 111 continuously introduces the spray liquid to the air vent 12, the film can further improve the contact degree between the smoke and the spray liquid during the continuous formation and breaking of the film.

[0061] On the basis of the above implementation, as a further limited implementation, the pallet is laid in the desulfurization tower after being assembled, and the reinforced structure 11 of the pallet can provide a connection basis, so that the pallet can be hoisted inside the desulfurization tower. There is no need to lay a truss structure inside the desulfurization tower, which further improves the efficiency of the desulfurization tower modification.

[0062] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
