Description

Technical Field

[0001] This utility model relates to the field of separator center cylinder technology, specifically a separator center cylinder. Background Technology

[0002] In conventional fluidized beds, fine particles do not reside long enough in the furnace, resulting in incomplete combustion and loss of larger fine carbon particles and unreacted CaO. Conversely, coarse particles reside for too long, affecting the effective utilization of the furnace volume. Therefore, improving separation efficiency will benefit boiler efficiency and CaO utilization, reduce the Ca / S ratio, and improve desulfurization efficiency. The main factors affecting separator efficiency are: tangential inlet velocity; flue gas temperature; particle size; inlet particle concentration; tangential inlet width and inlet type; separator cylinder diameter; and the height and diameter of the central cylinder. Since the swirling flow occurs between the central cylinder and the wall, the height of the central cylinder directly affects the performance of the cyclone separator. As the central cylinder height increases, the separation efficiency gradually increases. The highest separation efficiency is achieved when the central cylinder height is approximately 0.4 to 0.5 times the separator inlet height. Subsequently, the separation efficiency gradually decreases with further increases in central cylinder height. Both excessively long and excessively short central cylinders are detrimental to separation. Therefore, the detachment of the central cylinder will damage the normal swirling core, making it unstable, and at the same time cause a short circuit in the flue gas, resulting in a significant decrease in separation efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a separator center cylinder to solve the problem mentioned in the background art that the detachment of the center cylinder will cause damage to the normal swirling core, making it unstable, and at the same time cause short circuit of flue gas, resulting in a significant decrease in separation efficiency.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a separator center cylinder, comprising a center cylinder body and a connecting plate, wherein weld seams are distributed inside the center cylinder body, reinforcing ribs are fixed inside the weld seams, fixing plates are fixed on both sides inside the reinforcing ribs, and reinforcing rods are distributed between the fixing plates.

[0005] Preferably, the welds are evenly distributed inside the central cylinder, and two sets of reinforcing ribs are fixed inside each weld.

[0006] Preferably, the weld and the reinforcing rib are fixed together by welding, and the fixing pieces are distributed in pairs about the central axis of the reinforcing rib.

[0007] Preferably, the reinforcing rods are evenly distributed between the fixing plates, and the central cylinder and the connecting plate are welded together.

[0008] Preferably, a bracket block is fixed to the outer wall of the connecting plate, and a reinforcing connecting plate is fixed to the outer wall of the bracket block.

[0009] Preferably, the reinforcing connecting plates are evenly distributed on the outer side wall of the bracket block, the end face of the bracket block is fixed with a reinforcing rib plate, and the front end face of the reinforcing rib plate is fixed with a baffle plate.

[0010] Preferably, the outer side wall of the bracket connecting plate is evenly distributed, and the bracket, reinforcing connecting plate, reinforcing rib plate and baffle are all made of stainless steel.

[0011] Preferably, the reinforcing ribs are symmetrically distributed about the central axis of the baffle, and the thickness of the central cylinder is twelve millimeters.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the central cylinder of this separator has improved strength and resistance to deformation during use;

[0013] (1) By replacing components such as the central cylinder body and the bracket block, the thickness of the central cylinder body is changed from the original 16 mm to 12 mm, thereby reducing the weight of the central cylinder body. At the same time, the thickness of the bracket block is changed from the original 12 mm to 20 mm, thereby increasing the strength of the bracket block hook. In this way, while reducing the weight of the central cylinder body itself, the load-bearing capacity of the bracket block and the whole is improved. With the joint work of the bracket block, the reinforcing connecting plate, the reinforcing rib plate and the baffle plate, the reinforcing rib plate is fully welded between the central cylinder body and the hook to ensure the strength of the hook root and prevent the hook from deforming. The baffle plate is added to the end of the hook to prevent it from falling off. Therefore, the hook's resistance to deformation and its ability to prevent falling off are effectively improved.

[0014] (2) By distributing weld seams inside the central cylinder body, two reinforcing ribs are distributed inside the weld seams during welding. Fixing plates and reinforcing rods are fixed inside the reinforcing ribs, thereby improving the strength of use during distribution and preventing the phenomenon of weld seam cracking leading to deformation of the central cylinder body.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 One embodiment of this utility model is a separator center cylinder, including a center cylinder body 1 and a connecting plate 4. Weld seams 2 are distributed inside the center cylinder body 1. Reinforcing ribs 3 are fixed inside the weld seams 2. Fixing plates 9 are fixed on both sides inside the reinforcing ribs 3. Reinforcing rods 10 are distributed between the fixing plates 9.

[0021] Welds 2 are evenly distributed inside the central cylinder 1, and two sets of reinforcing ribs 3 are fixed inside each weld 2.

[0022] Welded fixation is formed between weld 2 and reinforcing rib 3, and fixing pieces 9 are distributed in pairs about the central axis of reinforcing rib 3.

[0023] The reinforcing rods 10 are evenly distributed between the fixing plates 9, and the central cylinder body 1 and the connecting plate 4 are welded together.

[0024] A bracket block 5 is fixed to the outer wall of the connecting plate 4, and a reinforcing connecting plate 6 is fixed to the outer wall of the bracket block 5.

[0025] The reinforcing connecting plates 6 are evenly distributed on the outer side wall of the bracket block 5. The end face of the bracket block 5 is fixed with a reinforcing rib plate 7, and the front end face of the reinforcing rib plate 7 is fixed with a baffle plate 8.

[0026] The outer side wall of the connecting plate 4 is evenly distributed with the bracket block 5. The bracket block 5, the reinforcing connecting plate 6, the reinforcing rib plate 7 and the baffle plate 8 are all made of S310 stainless steel.

[0027] The reinforcing ribs 7 are symmetrically distributed about the central axis of the baffle 8, and the thickness of the central cylinder 1 is twelve millimeters.

[0028] The further improved separator center cylinder not only effectively enhances the separator's separation effect, but also reduces the amount of fly ash discharged from the tail flue, reduces the number of leaks in the four tubes, and lowers the dust emission concentration by about 15 mg / Nm3, avoiding excessive dust emissions and environmental pollution, and creating favorable conditions for energy conservation and emission reduction. In addition, if the separator center cylinder falls off during operation, it will cause blockage of the boiler separator, seriously threatening the safe operation of the unit.

[0029] During the further assembly of the central cylinder body 1, two reinforcing ribs 3 are evenly arranged on each weld seam 2 inside to prevent the weld seam from cracking and causing the cylinder body to deform.

[0030] Working principle: First, during operation, components such as the central cylinder body 1 and the bracket block 5 are replaced. The thickness of the central cylinder body 1 is reduced from 16 mm to 12 mm, thereby reducing its weight. At the same time, the thickness of the bracket block 5 is increased from 12 mm to 20 mm, thereby increasing the hook strength of the bracket block 5. This reduces the weight of the central cylinder body 1 itself while improving the load-bearing capacity of the bracket block 5 and the whole structure. With the joint operation of the bracket block 5, the reinforcing connecting plate 6, the reinforcing rib plate 7, and the baffle plate 8, the reinforcing rib plate 7 is fully welded between the central cylinder body 1 and the hook to ensure the strength of the hook root and prevent hook deformation. The baffle plate 8 is installed at the end of the hook to prevent it from coming off.
