Description

TECHNICAL FIELD

[0001] The utility model relates to a coal economizer installation technical field, concretely relates to a kind of coal economizer support's hanging structure. BACKGROUND

[0002] At present, the fixed form of more commonly used coal economizer has two kinds: one is that serpentine pipe is connected together by pipe clamp, is fixed by bottom ventilation beam, this structure is limited by ventilation beam installation position, the tail flue of boiler can not have enough space, simultaneously, ventilation beam needs a large amount of steel material, makes the overall weight of boiler rise, and structural cost increases;Another structural form is that the hanging hook is installed on both sides of coal economizer guard plate and both sides of serpentine pipe, and the coal economizer is fixed by the hanging hook connection, this form is compact, reduces space occupancy, but poor stability, simultaneously, every hook needs to be connected, leading to the increase of on-site installation workload, and the work difficulty increases, reduces the installation efficiency of boiler, and there is certain security risk, simultaneously, because two are connected closely, it is inconvenient for the detection and maintenance of boiler later period.

[0003] In summary, the existing coal economizer hanging device is bulky, due to the limitation of ventilation beam installation position, it occupies a larger space inside the tail flue of boiler, thereby leading to the problem of poor stability of coal economizer hanging. UTILITY MODEL CONTENTS

[0004] The utility model discloses a kind of coal economizer support's hanging structure to solve the problem that the existing coal economizer hanging device is bulky, due to the limitation of ventilation beam installation position, it occupies a larger space inside the tail flue of boiler, thereby leading to the problem of poor stability of coal economizer hanging.

[0005] The utility model discloses a kind of coal economizer support's hanging structure, its composition includes bottom plate 1, support plate 2 and pipe clamp 4;

[0007] Further, the number n of the support plate 2 is 2≤n≤10;

[0008] Further, the distance between every two support plate 2 is 5cm~10cm;

[0009] Further, the number m of the pipe clamp 4 is 2≤m≤5;

[0010] Further, the utility model discloses a kind of coal economizer support's hanging structure further includes arc plate 3, the cross section of support plate 2 is L type, and the top surface arc opening end of support plate 2 is equipped with arc plate 3;

[0011] Furthermore, the arc plate 3 is fixedly connected to the upper surface of the base plate 1 by n support plates 2;

[0012] Furthermore, the hanging structure for economizer support also includes a U-shaped plate 5, with a U-shaped plate 5 provided at one end of the top surface of each support plate 2;

[0013] Furthermore, during use, the device can be installed at the top or bottom of the economizer serpentine tube, depending on the on-site installation conditions. When installed at the top of the economizer serpentine tube, the economizer serpentine tube needs to contact the U-shaped plate 5. Then, the number of pipe clamps 4 on the base plate is determined according to the length of the economizer serpentine tube, and the economizer serpentine tube is fixed to the base plate 1 by the pipe clamps 4.

[0014] When installed at the bottom of the economizer serpentine tube, remove the U-shaped plate 5 on the support plate 2, and fix the arc plate 3 to the upper surface of the base plate 1 through multiple support plates 2. The elbow at the bottom of the economizer serpentine tube is directly in contact with the arc plate 3 for fixation. Then, determine the number of pipe clamps 4 on the base plate according to the length of the economizer serpentine tube, and fix the economizer serpentine tube to the base plate 1 through the pipe clamps 4.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This invention overcomes the shortcomings of existing technologies by employing a base plate with multiple support plates evenly distributed along the width direction at one end of its upper surface, and multiple pipe clamps evenly distributed along the length direction at the middle of the other end of the base plate. An arc-shaped plate is fixedly connected to the upper surface of the base plate via these support plates, or a U-shaped plate is provided at one end of the top surface of each support plate. The compact structure saves considerable space inside the boiler's tail flue, providing better space for desulfurization and denitrification, thus saving energy and reducing emissions, and improving the stability of the economizer's hanging structure. Lowering the height of the tail flue effectively reduces boiler costs. Currently, the price of ordinary Q235B steel is approximately 5000 RMB / ton, and with processing and installation costs of 10,000 RMB / ton, lowering the tail flue of a typical 130t / h boiler by one meter can save about 10 tons of steel, resulting in a cost of approximately 100,000 RMB. Therefore, this invention effectively reduces boiler costs.

[0017] The economizer hanging device with this structure is easy to install on site, improving installation efficiency. On site, only the arc plate needs to be welded to the guard plate or steel section, and the pipe clamps and support plates need to be welded to the base plate. On-site operation is convenient, saving time and costs, improving work efficiency, and facilitating later maintenance with high safety. Attached Figure Description
