Description

Technical Field

[0001] The invention relates to the technical field of fluidized bed boilers, and in particular to an energy-saving fluidized bed boiler. Background Art

[0002] A fluidized bed boiler is a boiler that uses a fluidized bed combustion method. A circulating fluidized bed boiler uses a fluidized combustion method, which is a combustion method between the suspended combustion of a pulverized coal furnace and the fixed combustion of a chain furnace. Because the bottom of a fluidized bed boiler is mostly V-shaped, when pouring refractory coating on the bottom furnace of the fluidized bed boiler, it is impossible to directly cast it in one piece together with the bottom side wall of the boiler. It is necessary to manually build a mold to assist in the pouring. However, manual mold construction is time-consuming, and the subsequent vibration is also cumbersome. After the pouring is completed, the bottom of the boiler is mostly flat. When in use, the coal ash falls to the bottom of the wind hood and is difficult to be blown up again, causing the coal ash to accumulate and carbonize at the bottom of the wind hood, affecting the service life of the wind hood. Summary of the invention

[0003] The main purpose of the present invention is to provide an energy-saving fluidized bed boiler.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] An energy-saving fluidized bed boiler, comprising a plurality of furnace bottom templates for assisting operators in pouring refractory coating on the furnace bottom of the fluidized bed boiler and a furnace side wall template for assisting operators in pouring refractory coating on the furnace bottom side wall of the fluidized bed boiler, the furnace bottom template is provided with a plurality of conical clearance holes for engaging with the hood pipe at the furnace bottom of the fluidized bed boiler, the top surfaces of the plurality of conical clearance holes are slidably connected with sliding top caps for assisting installation personnel in confirming whether the conical clearance holes are engaged with the hood pipe, and a plurality of conical clearance holes are provided between the two furnace side wall templates. A plurality of linkage support rods are provided for supporting the furnace side wall formwork, the linkage support rods are provided with a plurality of extrusion transmission rods for extruding the sliding top cap, the linkage support rods are slidably connected with a plurality of sliding connectors for connecting the extrusion transmission rods, the extrusion transmission rods are slidably connected in the sliding connectors, the furnace side wall formwork is rotatably connected to the side edge of the top surface of the furnace bottom formwork by a hinge, a vibration element for vibrating the poured refractory coating is provided above the sliding top cap, and the vibration element is buckled with the extrusion transmission rod.

[0006] A further improvement of the present invention is that template splicing grooves for cooperating with the furnace bottom templates for splicing are provided on both sides of several of the furnace bottom templates, and template splicing blocks for cooperating with the template splicing grooves for splicing are fixedly connected on both sides of the opposite sides of several of the furnace bottom templates and the template splicing grooves.

[0007] A further improvement of the present invention is that a number of equally spaced T-shaped chutes are provided on the side of the furnace sidewall formwork away from the fluidized bed boiler, and a partition formwork for separating the casting material is slidably connected in the T-shaped chutes.

[0008] A further improvement of the present invention is that buckle holes are provided on both sides of the formwork splicing groove, an insertion buckle plate for cooperating with the buckle holes to fix the splicing of a number of the furnace bottom formworks is slidably connected in the formwork splicing block, and a pushing block for driving the insertion buckle plate to slide is slidably connected to the top of the formwork splicing block.

[0009] A further improvement of the present invention is that an anti-slip protective rubber sleeve is fixedly connected to the inner wall of the conical relief hole, and a blocking rubber sleeve for blocking the casting material is fixedly connected in the conical relief hole.

[0010] A further improvement of the present invention is that both ends of the linkage support rod are connected to the furnace sidewall formwork through connecting lugs, the connecting lugs are connected to the T-shaped chutes in a damped sliding manner, and the linkage support rod is connected to the connecting lugs in an insertion and buckling manner.

[0011] A further improvement of the present invention is a usage process of an energy-saving fluidized bed boiler, including:

[0012] S1. When pouring refractory coatings at the bottom of the furnace in a fluidized bed boiler, since the bottom surface of the fluidized bed is a V-shaped inclined plane, it is difficult to pour directly, and it is impossible to ensure the flatness after pouring. Therefore, a mold is selected to assist the operator in pouring refractory coatings at the bottom of the fluidized bed. First, before pouring, the operator transports several furnace bottom templates into the fluidized bed boiler. Subsequently, an installation is made starting from the outermost edge of the bottom surface of the fluidized bed boiler. During installation, the operator places the furnace bottom template above the air cap pipes at the bottom of the furnace in the fluidized bed boiler. Then, the furnace bottom template is moved so that the air cap pipe is inserted into the conical relief hole opened in the furnace bottom template. After the air cap pipe is inserted into the conical relief hole, the sliding top cap in the conical relief hole is lifted. The operator confirms whether the four sides of the furnace bottom template are skewed according to the height at which the sliding top caps at various positions of the furnace bottom template are lifted, so as to avoid uneven pouring surfaces caused by the skew installation of the furnace bottom template during subsequent pouring, resulting in subsequent fuel accumulation in the concave areas, forming coking, and affecting the service life of the refractory coating. After the installation of the furnace bottom template is completed, the operator aligns the template splicing block of another furnace bottom template with the template splicing groove of the installed furnace bottom template. Then, the other furnace bottom template is pressed downwards so that the template splicing block is inserted and buckled in the template splicing groove. Subsequently, the operator pushes the pushing block so that the inserting buckle plate is inserted into the inserting buckle hole for fixation, to prevent the furnace bottom template from being lifted when the subsequent refractory coating condenses. Then, the operator uses this method to cover the entire bottom of the furnace in the fluidized bed boiler with several furnace bottom templates, covering the pouring surface at the bottom of the furnace;

[0013] S2. After the installation of several furnace bottom templates is completed, the operator places the partition template on one side close to the furnace wall of the furnace side wall template, and then inserts the partition template into the T-shaped chute for limit fixation. According to the operation requirements, several partition templates are inserted into the T-shaped chute to separate the cast refractory materials, providing expansion gaps for the refractory materials to avoid cracks caused by the expansion of the refractory materials during subsequent use. After the placement of the partition template is completed, the operator flips the furnace side wall template so that the furnace side wall template abuts against the furnace wall, adjusts the rotation angle of the furnace side wall template according to the pouring thickness, and then locks the rotation of the furnace side wall template. After the rotation of the two furnace side wall templates is completed, the operator inserts and buckles the two ends of the linkage support rod with the connecting lugs in the two T-shaped chutes, and supports the two furnace side wall templates through the linkage support rod to prevent the furnace side wall template from being flipped under the force during pouring. After the installation of the linkage support rod is completed, the operator slides the sliding connector to make the position of the extrusion drive rod correspond to that of the sliding top cap, and then rotates the hand-tightening screw on the sliding connector to unlock the sliding of the extrusion drive rod, so that the extrusion drive rod presses on the top surface of the sliding top cap. Then the operator turns the hand-tightening screw on the sliding connector again to lock the sliding of the extrusion drive rod to ensure the subsequent conduction of vibration. Then the operator installs in this way to make the extrusion drive rod press on all the sliding top caps;

[0014] S3. After the installation is completed, the operator buckles the vibration element between the two extrusion drive rods, and then pours the refractory coating through the gap between the furnace side wall template and the furnace side wall to pour the fireproof coating on the furnace bottom. After the pouring is completed, the operator starts the vibration element. The vibration generated by the vibration element is conducted through the extrusion drive rod. After the vibration is transmitted to the sliding top cap, it is transmitted to the air cap pipe that is in extrusion contact with the sliding top cap. The air cap pipe drives the cast refractory coating to vibrate during vibration, discharging the air in the coating to avoid the appearance of air holes inside the coating in the future, increasing the strength and service life of the coating. During the vibration of the vibration element, the vibration is transmitted to the two furnace side wall templates through the linkage support rod, causing the furnace side wall templates to vibrate to assist in pouring and vibrating and exhausting the refractory coating between the furnace side wall template and the furnace side wall. After the exhaust is completed, the operator turns off the vibration element and waits for the coating to solidify. After the coating solidifies, the operator removes the formwork for subsequent reuse. A cone will form around the air cap pipe during pouring to prevent subsequent fuel from accumulating under the air cap.

[0015] Compared with the prior art, the conical groove inside the conical relief hole is engaged with the wind cap tube, so that the furnace bottom template is pressed above the wind cap tube. The refractory material entering the conical relief hole during pouring will form a cone after solidification, which can effectively avoid fuel accumulation and carbonization under the wind cap during subsequent use, improve the service life of the wind cap. At the same time, the vibration generated by the vibration element is transmitted through the extrusion drive rod. After the vibration is transmitted to the sliding top cap, it is transmitted to the wind cap tube in extrusion contact with the sliding top cap. The wind cap tube drives the poured refractory coating to vibrate during vibration, exhausting the air in the coating and avoiding the appearance of pores inside the coating subsequently.

The buckle hole 111 is used to cooperate with the buckle plate 121 for splicing and fixing. The buckle plate 121 is driven to slide by pushing the pushing block 122, and the buckle plate 121 is inserted into the buckle hole 111 for limited fixation. Several furnace bottom templates 1 are connected in series into a whole to avoid lifting one of the furnace bottom templates 1 when the casting material solidifies and expands.

[0030] A use process of an energy-saving fluidized bed boiler. When pouring refractory coating on the bottom of the furnace in the fluidized bed boiler, it is difficult to pour directly because the bottom surface of the fluidized bed is a V-shaped slope, and the flatness after pouring cannot be guaranteed. Therefore, a mold is used to assist the operator in pouring the refractory coating on the bottom of the fluidized bed. First, before pouring, the operator transports several furnace bottom templates 1 to the inside of the fluidized bed boiler, and then opens and installs them from the edge of the bottom surface of the fluidized bed boiler. During installation, the operator places the furnace bottom template 1 above the hood pipe at the bottom of the furnace in the fluidized bed boiler, and then moves the furnace bottom template 1 to insert the hood pipe into the conical clearance hole 13 opened in the furnace bottom template 1. After the hood pipe is inserted into the conical clearance hole 13, The sliding top cap 2 in the conical clearance hole 13 is lifted up, and the operator confirms whether the surrounding areas of the furnace bottom template 1 are skewed according to the lifted height of the sliding top cap 2 at each position of the furnace bottom template 1, so as to avoid uneven casting surface due to the skewed installation of the furnace bottom template 1 during subsequent pouring, resulting in accumulation of subsequent fuel in the concave place, forming coking, and affecting the service life of the refractory coating. After the furnace bottom template 1 is installed, the operator aligns the template splicing block 12 of another furnace bottom template 1 with the template splicing groove 11 of the installed furnace bottom template 1, and then presses the other furnace bottom template 1 downward to make the template splicing block 12 buckle in the template splicing groove 11, and then the operator pushes the pushing block 122 to insert the buckle plate 121 into the buckle hole 111 to fix it, so as to prevent the furnace bottom template 1 from being lifted up when the subsequent refractory coating solidifies. Then the operator uses this method to spread several furnace bottom templates 1 all over the furnace bottom of the fluidized bed boiler, and covers the casting surface of the furnace bottom. After the installation of several furnace bottom templates 1 is completed, the operator places the partition template 32 on the side of the furnace side wall template 3 close to the furnace wall, and then inserts the partition template 32 into the T-shaped slide groove 31 for limit fixing. According to the operation requirements, several partition templates 32 are inserted into the T-shaped slide groove 31 to separate the poured refractory materials, provide expansion gaps for the refractory materials, and avoid cracks caused by the expansion of the refractory materials during subsequent use. After the partition template 32 is placed, the operator turns over the furnace side wall template 3 Make the furnace side wall template 3 close to the furnace wall, adjust the rotation angle of the furnace side wall template 3 according to the casting thickness, and then rotate and lock the furnace side wall template 3. After the rotation of the furnace side wall templates 3 on both sides is completed, the operator plugs and connects the two ends of the linkage support rod 4 with the connecting ears 43 in the T-shaped slide grooves 31 on both sides, and supports the furnace side wall templates 3 on both sides through the linkage support rod 4 to prevent the furnace side wall template 3 from being overturned due to force during casting. After the linkage support rod 4 is installed, the operator slides the sliding connector 42 to make the extrusion transmission rod 41 correspond to the position of the sliding top cap 2, and then rotates the hand screw on the sliding connector 42 to unlock the sliding of the extrusion transmission rod 41, so that the extrusion transmission rod 41 is squeezed on the top surface of the sliding top cap 2.Subsequently, the operator turns the hand-tightening screw on the sliding connecting member 42 again to lock the sliding of the extrusion drive rod 41, ensuring the subsequent vibration conduction. Then the operator installs it in this way, so that the extrusion drive rod 41 extrudes all the sliding top caps 2. After the installation is completed, the operator snap-connects the vibration element 21 between the two extrusion drive rods 41. Then the refractory coating is poured through the gap between the furnace sidewall formwork 3 and the furnace sidewall to pour the fireproof coating on the furnace bottom. After the pouring is completed, the operator starts the vibration element 21. The vibration generated by the vibration element 21 is conducted through the extrusion drive rod 41. After the vibration is transmitted to the sliding top cap 2, it is transmitted to the wind cap pipe that is in extrusion contact with the sliding top cap 2. The wind cap pipe drives the poured refractory coating to vibrate during vibration, discharging the air in the coating, avoiding the appearance of pores inside the subsequent coating, and increasing the strength and service life of the coating. During the vibration of the vibration element 21, the vibration is transmitted to the furnace sidewall formworks 3 on both sides through the linkage support rod 4, causing the furnace sidewall formworks 3 to vibrate to assist in pouring and vibrating and exhausting the air of the refractory coating on the furnace sidewall. After the air exhaust is completed, the operator turns off the vibration element 21 and waits for the coating to solidify. After the coating solidifies, the operator removes the formwork for subsequent reuse. When pouring, a cone will form around the wind cap pipe to prevent subsequent fuel from accumulating under the wind cap.,

Then, the operator installs it in this way so that the extrusion transmission rod (41) presses on all the sliding top caps (2); S3. After the installation is completed, the operator snap-connects the vibration element (21) between the two extrusion transmission rods (41), and then pours the refractory coating through the gap between the furnace sidewall template (3) and the furnace sidewall to pour the fireproof coating on the furnace bottom. After the pouring is completed, the operator starts the vibration element (21). The vibration generated by the vibration element (21) is transmitted through the extrusion transmission rod (41). After the vibration is transmitted to the sliding top cap (2), it is transmitted to the wind cap tube in extrusion contact with the sliding top cap (2). The wind cap tube drives the poured refractory coating to vibrate during vibration, discharging the air in the coating to avoid the appearance of pores inside the coating in the future, increasing the strength and service life of the coating. During the vibration of the vibration element (21), the vibration is transmitted to the two furnace sidewall templates (3) through the linkage support rod (4), causing the furnace sidewall templates (3) to vibrate to assist in pouring and vibrating and exhausting the air from the refractory coating between the furnace sidewall template (3) and the furnace sidewall. After the exhaust is completed, the operator turns off the vibration element (21) and waits for the coating to solidify. After the coating solidifies, the operator removes the formwork for subsequent reuse. During pouring, a cone will form around the wind cap tube to prevent subsequent fuel from accumulating under the wind cap.
