Description

Technical Field

[0001] The utility model belongs to the technical field of synthesis furnace looper structures, in particular to an improved corrugated compensation type looper structure for a synthesis furnace. Background Art

[0002] At present, the second looper 3 of the synthesis furnace is inserted into the furnace wall 4 of the synthesis furnace in a socket-and-spigot manner, and the third flange 5 at the bottom of the furnace wall 4 of the synthesis furnace is connected to the fourth flange 6 sleeved on the outer wall of the second looper 3 by fasteners, and the two flanges are sealed by a sealing ring 7. However, this socket-and-spigot connection method easily causes superheated water in the synthesis furnace to easily flow out from between the furnace wall 4 of the synthesis furnace and the second looper 3, and flow out from between the third flange 5 and the fourth flange 6. In addition, this socket-and-spigot design leaks frequently, and the number of maintenance services required each year due to leakage of the synthesis furnace looper is relatively high. Therefore, in addition to replacing the looper seal each time, the maintenance cost and production cost of the synthesis furnace are seriously increased.

[0003] However, after comparing the working parameters and judging by experience, it is urgent to modify the looper of the synthesis furnace, and the cost of the modification should not be too high. If the cost is too high, it will seriously increase the production cost of the synthesis furnace. Therefore, an improved corrugated compensation looper structure for the synthesis furnace is designed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an improved corrugated compensation looper structure for a synthesis furnace, which solves the above-mentioned problems of leakage of the looper of the synthesis furnace and excessively high transformation cost, thereby increasing production cost.

[0005] In order to solve the above technical problems, the utility model provides an improved corrugated compensation looper structure for a synthesis furnace, wherein the looper structure includes a first flange, a telescopic member and a second flange installed below a first looper of the synthesis furnace, a first superheated water channel is formed between the first flange and the outer wall of the synthesis furnace, a second superheated water channel is formed between the telescopic member and the outer wall of the synthesis furnace, the first superheated water channel is connected to the second superheated water channel, and is connected to the first looper of the synthesis furnace, the cross-section of the telescopic member is annular, and it is fixedly arranged between the first flange and the second flange, and the first flange and the second flange are both connected to the flange on the outer wall of the synthesis furnace by fasteners.

[0006] Furthermore, the first flange, the second flange and the telescopic member are an integrally formed structure.

[0007] Furthermore, the telescopic part is a corrugated cylinder, and the height of the corrugated cylinder is 300-400 mm, the wall thickness is 5-6 mm, the telescopic amount is 15-50 mm, and the pressure bearing capacity is 0.1-1.6 MPa.

[0008] Furthermore, the material of the corrugated cylinder is 304 stainless steel.

[0009] Furthermore, the first flange and the second flange are made of Q235b steel.

[0010] Furthermore, the maximum outer diameter of the corrugated cylinder is smaller than the outer diameters of the first flange and the second flange, and larger than the outer diameter of the synthesis furnace body.

[0011] Furthermore, the minimum inner diameter of the corrugated cylinder is equal to the inner diameter of the first flange, and is equal to the maximum inner wall diameter of the first looper of the synthesis furnace.

[0012] Furthermore, the vertical cross-section of the corrugated cylinder is formed by a plurality of C-shapes that are opposite and staggered.

[0013] The beneficial effects of the present invention are as follows: the design of the loop structure being installed below the first loop of the synthesis furnace in the present invention can effectively allow the superheated water in the first loop above the synthesis furnace to flow smoothly into the first superheated water channel and the second superheated water channel. In addition, due to the elasticity of the telescopic member, when the superheated water fills the telescopic member, it pushes the telescopic member to stretch, so that the first flange fits tightly with the flange at the bottom of the first loop, thereby preventing the superheated water from leaking from between the conventional second loop and the synthesis furnace body, thereby solving the problem of liquid leakage in the synthesis furnace.

[0014] The first flange, the second flange and the telescopic member are designed with an integrated structure, which can effectively prevent the risk of the three parts being separated due to excessive temperature or pressure of superheated water, thereby preventing the risk of superheated water leaking from the separation gap, and effectively improve the durability of the looper structure;

[0015] The limited size of the telescopic part can not only enable it to withstand the pressure brought by superheated water, but also play a telescopic role and abut more tightly with the upper flange to prevent the risk of superheated water leakage;

[0016] The limitation of the material of the corrugated cylinder and the materials of the first flange and the second flange can effectively reduce the manufacturing cost of the looper structure, thereby greatly reducing the production cost of the synthesis furnace;

[0017] The vertical section of the corrugated cylinder and the limitation of the maximum inner diameter and the minimum inner diameter can enable the superheated water to flow smoothly from the first looper to between the corrugated cylinder and the synthesis furnace body, thereby improving the fluidity of the superheated water.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings of the present invention specification to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the embodiments described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the utility model.

[0024] The following is a specific embodiment of the present invention and the attached Figure 1-3To explain in detail, an improved corrugated compensation looper structure for a synthesis furnace is specifically disclosed. The looper structure 1 includes a first flange 11, a telescopic member 13, and a second flange 12 installed below a first looper 21 of a synthesis furnace 2. A first superheated water channel 14 is formed between the first flange 11 and the outer wall of the synthesis furnace 2. A second superheated water channel 15 is formed between the telescopic member 13 and the outer wall of the synthesis furnace 2. The first superheated water channel 14 is connected to the second superheated water channel 15 and is connected to the first looper 21 of the synthesis furnace 2. The cross section of the telescopic member 13 is annular and is fixedly arranged on the first flange. The design of the loop structure 1 being installed below the first loop 21 of the synthesis furnace 2 between the second loop 11 and the second flange 12 can effectively allow the superheated water in the first loop 21 above the synthesis furnace to flow smoothly into the first superheated water channel 14 and the second superheated water channel 15. In addition, due to the elasticity of the telescopic member 13, when the superheated water fills the telescopic member 13, it pushes the telescopic member 13 to stretch, so that the first flange 11 and the flange below the first loop 21 are tightly fitted, thereby preventing the superheated water from leaking from between the conventional second loop 3 and the furnace body of the synthesis furnace 2, thereby solving the problem of liquid leakage in the synthesis furnace 2;

[0025] The first flange 11 and the second flange 12 are both connected to the flange on the outer wall of the synthesis furnace 2 through fasteners. The material of the first flange 11 and the second flange 12 is Q235b steel, and the material of the corrugated cylinder is 304 stainless steel. The limitation of the material of the corrugated cylinder and the material of the first flange 11 and the second flange 12 can effectively reduce the manufacturing cost of the loop structure 1, thereby greatly reducing the production cost of the synthesis furnace 2.

[0026] The first flange 11, the second flange 12 and the telescopic member 13 are an integrally formed structure. The integrally formed structure design can effectively prevent the risk of the superheated water temperature or pressure being too high, which may cause the three to separate and leak out of the separation gap, thereby effectively improving the durability of the loop structure 1.

[0027] The telescopic member 13 is a corrugated cylinder with a height of 300-400 mm, a wall thickness of 5-6 mm, a telescopic range of 15-50 mm, and a pressure-bearing capacity of 0.1-1.6 MPa. The size of the telescopic member 13 is limited so that it can withstand the pressure brought by superheated water while also being able to play a telescopic role and abut more tightly with the upper flange to prevent the risk of superheated water leakage;

[0028] The maximum outer diameter of the corrugated cylinder is smaller than the outer diameters of the first flange 11 and the second flange 12, and larger than the outer diameter of the synthesis furnace 2 body. The minimum inner diameter of the corrugated cylinder is equal to the inner diameter of the first flange 11, and equal to the maximum inner wall diameter of the first looper 21 of the synthesis furnace 2. The vertical cross-section of the corrugated cylinder is formed by a plurality of relative and staggered C-shapes. The vertical cross-section of the corrugated cylinder and the limitation of the maximum inner diameter and the minimum inner diameter can enable the superheated water to flow smoothly from the first looper 21 to between the corrugated cylinder and the synthesis furnace 2 body, so as to improve the fluidity of the superheated water.

[0029] The workflow of this utility model:

[0030] The superheated water of the synthesis furnace 2 enters the first looper 21 from the inlet on the side wall of the synthesis furnace 2, and flows into the second superheated water channel 15 after passing through the first superheated water channel 14 between the first flange 11 and the synthesis furnace 2. As the superheated water increases, the telescopic member 13 on the looper structure 1 expands and contracts under the pressure of the superheated water, so that the first flange 11 and the second flange 12 at both ends of the telescopic member 13 extend upward and downward, the first flange 11 abuts against the flange connected to the bottom of the first looper 21, and the second flange 12 abuts against the upper end connection flange of the cooling water looper of the synthesis furnace 2, effectively eliminating the gap between the flanges to prevent leakage of superheated water. At the same time, the superheated water in the first superheated water channel 14 and the second superheated water channel 15 is converted into gas through the evaporation part and evaporates out from the evaporation port on the side wall of the synthesis furnace 2, effectively solving the problem of superheated water leakage.

[0031] The above disclosure is only a preferred embodiment of the present invention and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
