Description

Technical Field

[0001] The present invention relates to the technical field of cogeneration and power generation, in particular to a polygeneration power generation device and method for cogeneration of heat and power. Background Art

[0002] Cogeneration is a thermodynamically efficient use of fuel. In stand-alone electricity production, some of the energy must be discarded as waste heat, but in cogeneration, some of this heat is put to use. All the heat emitted by thermal power plants during power generation can be released into the natural environment through cooling towers, flue gases or by other means. On the contrary, cogeneration captures some or all of the by-products used for heating. Cogeneration can reuse energy very well, which not only improves power generation efficiency but also saves resource consumption.

[0003] The existing patent: 201510150138.4 is a coal gas and pulverized coal coordinated power generation, multi-generation device and method, which can realize the efficient, cascade and comprehensive utilization of coal resources, thereby combining coal-fired power generation technology and coal-based clean liquid fuel production technology to realize coal-based energy multi-generation and cascade efficient utilization of coal resources.

[0004] However, in the whole process, the boiler plays an important role. The burner connected to one end of the boiler works to spray the coal powder and air mixture into the boiler for ignition, thereby continuously heating the inside of the boiler.

In addition, the burner is heavy and difficult to move, which makes it very inconvenient for subsequent cleaning and maintenance. At the same time, the ladder on the boiler is not convenient for safe adjustment of the position, which is not conducive to the staff to accurately check the position that needs maintenance.

Through the installation of the plurality of guide rods 204, the burner 201 is stably connected to the boiler 1 and will not rotate, thereby playing a role in guiding and positioning.

[0045] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the moving mechanism 3 includes a support plate 301, a support plate 301 is installed on the top of the support frame 202, two parallel guide rails 303 are installed on the support plate 301, and a plurality of sliders 302 are slidably connected to the two guide rails 303, respectively, a slide plate 304 is provided on the top of the support plate 301, and the slide plate 304 is slidably connected to the top of the support plate 301 through a plurality of sliders 302 and two guide rails 303, and the bottom of the burner 201 is connected to the slide plate 304, and the installation of the support plate 301 facilitates the connection of the slide block 302 and the guide rail 303, thereby realizing the sliding installation of the slide plate 304, and the installation of the slide plate 304 enables the burner 201 to be connected, and can drive the movement of the burner 201, thereby realizing the rapid disassembly and assembly of the burner 201, and facilitating subsequent maintenance.

[0046] Specifically, Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the braking mechanism 4 includes an oblique rack 401, an oblique rack 401 is installed at the top midline of the support plate 301, a tooth block 403 is installed on the inner side of the midline of one end of the slide plate 304, the tooth block 403 is slidably connected to the inside of the slide plate 304 through a compression spring 404, the bottom of the tooth block 403 extends to the outside of the bottom of the slide plate 304 and contacts the oblique rack 401, the bottom of the tooth block 403 is a tooth-shaped structure, the sharp teeth at the bottom of the tooth block 403 are in opposite directions to the sharp teeth of the oblique rack 401, a handle 402 is slidably connected to the top of the slide plate 304, the bottom of the handle 402 is connected to the top of the tooth block 403, and the tooth block 403 is pressed against the compression spring by the installation of the oblique rack 401. The tooth block 403 contacts the bevel rack 401 under the interference of the compression spring 404. Since the sharp teeth at the bottom of the tooth block 403 are in opposite directions to the sharp teeth of the bevel rack 401, the handle 402 is pushed, and the slide plate 304 slides on the support plate 301. The tooth block 403 moves with the bevel rack 401 under the cooperation of the compression spring 404. At the same time, the tooth block 403 cannot slide in the opposite direction, so that the burner 201 cannot be loosened after being connected to the boiler 1. The burner 201 and the boiler 1 are firmly installed after being inserted. By pulling the handle 402, the tooth block 403 is separated from the bevel rack 401, and the slide plate 304 can move freely, so that the burner 201 can be disassembled and maintained.

[0047] Specifically, Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the rotating mechanism 5 includes a rotating groove 501, a rotating groove 501 is provided on the top of the slide plate 304, the bottom of the burner 201 is rotatably connected to the inside of the rotating groove 501, a protrusion 502 is installed at the bottom edge of the burner 201, and the protrusion 502 is slidably connected to the inner side of the bottom of the burner 201 through a resistance spring 504, the bottom of the protrusion 502 is a hemispherical structure, and a plurality of annularly distributed grooves 503 are provided at the inner edge of the rotating groove 501, and the bottom of the protrusion 502 is in friction with the inside of one of the grooves 503, and the opening of the rotating groove 501 facilitates the bottom of the burner 201 to rotate with the inside of the rotating groove 501 through the bearing, so that The burner 201 can be rotated in multiple directions on the top of the slide plate 304, which is convenient for maintenance work. Through the interference of the interference spring 504, the protrusion 502 is in conflict with the inside of the groove 503, which plays a role of limiting. The burner 201 is rotated by a certain torque, and the protrusion 502 is in conflict with the inner side of the groove 503. The protrusion 502 is freed from the elastic contraction of the interference spring 504, which facilitates the separation of the protrusion 502 from the inside of the groove 503, so that the burner 201 can be rotated to a certain angle, and then the protrusion 502 continues to engage with another groove 503 to achieve limiting, which is convenient for maintenance work on the burner 201.

The top of the limiting rod 801 extends to the inside of the rotating groove 501 and engages with the inside of the limiting hole 802. The bottom of the limiting rod 801 extends to the outside of the bottom of the slide plate 304. The bottom of the limiting rod 801 is rotatably connected with a guide wheel 804, and the guide wheel 804 conflicts with the bottom side of the guide groove 805. After the burner 201 is stably connected to the boiler 1, the limiting rod 8 01, the guide wheel 804 at the bottom conflicts with the guide groove 805, so that the limit rod 801 is free from the elastic force of the extrusion spring 803 and slides, and the limit rod 801 is inserted into the limit hole 802, so that the burner 201 cannot rotate. After the burner 201 is separated from the boiler 1, the guide wheel 804 slides inside the guide groove 805. After the slide plate 304 slides into place, the guide wheel 804 slides to the end of the guide groove 805. Since the end of the guide groove 805 is deep, the guide wheel 804 is separated from the bottom of the guide groove 805 and cannot conflict with each other. The limit rod 801 slides down under the action of the extrusion spring 803, and the limit rod 801 is separated from the limit hole 802, which is convenient for the rotation and maintenance of the burner 201.

[0049] Specifically, Figure 1 , Fig.10 and Fig.11 As shown, the maintenance mechanism 6 includes a maintenance platform 601, and the maintenance platform 601 is installed on the top of the boiler 1.

Two support rods 603 are vertically connected to the bottom of the ladder 602, and one end of the two support rods 603 respectively contacts one side of the bottom of the boiler 1. The installation of the maintenance platform 601 is convenient for the staff to operate and maintain at the top. The installation of the ladder 602 is convenient for the staff to climb to the top of the boiler 1 for maintenance. The contact between the two support rods 603 makes the ladder 602 more stable and has better support strength.

[0050] Specifically, Figure 1 , Fig.10 , Fig.11 and Fig.12As shown, the limiting mechanism 7 includes a slide bar 701, a slide bar 701 is installed on one side of the maintenance platform 601, a slot 705 is provided on one side of the top of the ladder 602, and the top side of the ladder 602 is slidably connected to the slide bar 701 through the slot 705. The ladder 602 is slidably connected to one side of the boiler 1 through the slide bar 701. Through the installation of the slide bar 701, the ladder 602 can slide into position, which is convenient for staff to maintain the designated position and the operation is more convenient.

[0051] Specifically, Figure 1 and Fig.12 As shown, a spur rack 702 is installed on one side of the maintenance platform 601, and two limit blocks 706 are installed inside the top side of the ladder 602. The limit block 706 is slidably connected to the inside of the ladder 602 through a telescopic spring 707.

One side of the magnetic block 704 is adsorbed on the outer side of the magnetic plate 703. Through the installation of the magnetic plate 703, the magnetic block 704 is adsorbed on the magnetic plate 703, so that the support rod 603 is stably connected to one side of the bottom of the boiler 1 and is not easy to loosen, so that the ladder 602 will not loosen, thereby playing a role of safety protection.

[0053] A method for operating a polygeneration power generation device for cogeneration of heat and power, comprising the following steps:

[0054] S1: First, the brake mechanism 4 is driven to make the moving mechanism 3 drive the ignition mechanism 2 to separate from the boiler 1. After the moving mechanism 3 moves to a certain position, the control mechanism 8 releases the limit, which facilitates the rotation of the ignition mechanism 2 and enables the staff to clean and maintain the ignition mechanism 2;

[0055] S2: After the maintenance is completed, the ignition mechanism 2 is rotated to reset, and then the moving mechanism 3 is pushed to insert the ignition mechanism 2 into the boiler 1. At this time, the control mechanism 8 always limits the moving mechanism 3, so that the connection between the ignition mechanism 2 and the boiler 1 is stable;

[0056] S3: Subsequently, the high-volatile low-quality coal raw material is crushed, screened, and dried, and the powder is added to the raw coal bunker, and then processed through multiple devices, so that the processed coal powder is transported to the ignition mechanism 2 for ignition and combustion, thereby continuously heating the inside of the boiler 1, and the superheated steam is discharged through multiple heat exchanges to drive the generator set to generate electricity;

[0057] S4: By swinging the maintenance mechanism 6 upward, the maintenance mechanism 6 drives the limiting mechanism 7 to release the limit, which makes it convenient to move the maintenance mechanism 6 and enables the staff to maintain the designated position. When the staff climbs the maintenance mechanism 6, the maintenance mechanism 6 is squeezed, so that the limiting mechanism 7 is locked, so that the maintenance mechanism 6 will not move, which is convenient for the staff to work safely.

[0058] When the present invention is in use, the installation of the support frame 202 facilitates the support installation of the burner 201, so that the burner 201 is stably connected to one end of the boiler 1 and will not shake, causing damage to the equipment, so that the boiler 1 can work stably. The installation of the sealing ring 203 makes the burner 201 and the boiler 1 stably connected and has good sealing performance. The installation of multiple guide rods 204 makes the burner 201 and the boiler 1 stably connected and will not rotate, playing a guiding and positioning role. The installation of the support plate 301 facilitates the connection of the slider 302 and the guide rail 303, thereby realizing the sliding installation of the slide plate 304. The installation of the slide plate 304 connects the burner 201 and can drive the movement of the burner 201 to realize the rapid disassembly of the burner 201. The installation is convenient for subsequent maintenance. By installing the bevel rack 401, the tooth block 403 is in conflict with the bevel rack 401 under the interference of the compression spring 404. Since the sharp teeth at the bottom of the tooth block 403 are in opposite directions to the sharp teeth of the bevel rack 401, the handle 402 is pushed, and the slide plate 304 slides on the support plate 301. The tooth block 403 moves with the bevel rack 401 under the cooperation of the compression spring 404. At the same time, the tooth block 403 cannot slide in the opposite direction, so that the burner 201 cannot be loosened after being connected to the boiler 1. The burner 201 and the boiler 1 are firmly installed after being inserted. By pulling the handle 402, the tooth block 403 is separated from the bevel rack 401, and the slide plate 304 can move freely, so that the burner 201 can be disassembled and maintained. The opening of the rotating groove 501 is conducive to the bottom of the burner 201 The burner 201 can be rotated in multiple directions on the top of the slide plate 304 through the bearing and the rotation groove 501, which is convenient for maintenance work. The protrusion 502 is in conflict with the inside of the groove 503 through the conflict of the conflict spring 504, which plays a role of limiting. The burner 201 is rotated through a certain torque, and the protrusion 502 is in conflict with the inner side of the groove 503. The protrusion 502 is freed from the elastic contraction of the conflict spring 504, which facilitates the separation of the protrusion 502 from the inside of the groove 503, so that the burner 201 can be rotated to a certain angle. Then the protrusion 502 continues to engage with another groove 503 to achieve limiting, which is convenient for maintenance work on the burner 201. After the burner 201 is stably connected to the boiler 1, the guide wheel 804 at the bottom of the limit rod 801 conflicts with the guide groove 805 , so that the limit rod 801 is freed from the elastic force of the extrusion spring 803 and slides, and the limit rod 801 is inserted into the limit hole 802, so that the burner 201 cannot rotate. After the burner 201 is separated from the boiler 1, the guide wheel 804 slides inside the guide groove 805. After the slide plate 304 slides into place, the guide wheel 804 slides to the end of the guide groove 805. Since the end of the guide groove 805 is deep, the guide wheel 804 is separated from the bottom of the guide groove 805 and cannot conflict with each other. The limit rod 801 slides down under the action of the extrusion spring 803, and the limit rod 801 is separated from the limit hole 802, which is convenient for the burner 201 to rotate and maintain. The installation of the maintenance platform 601 is conducive to the staff to operate and maintain at the top. The installation of the ladder 602 is convenient for the staff to climb to the top of the boiler 1 for maintenance.The two support rods 603 are in conflict with each other, so that the ladder 602 has better stable support strength. The installation of the slide bar 701 allows the ladder 602 to slide to a position, which is convenient for the staff to maintain the designated position and is more convenient to operate. The limit block 706 is meshed with the spur rack 702 through the conflict of the telescopic spring 707, and the ladder 602 and the slide bar 701 cannot slide, which plays a limiting role. By rotating the ladder 602 in advance, the ladder 602 drives the limit block 706 to separate from the spur rack 702, so as to facilitate the adjustment of the position of the ladder 602. By installing the magnetic plate 703, the magnetic block 704 is adsorbed with the magnetic plate 703, so that the support rod 603 is stably connected to the bottom side of the boiler 1 and is not easy to loosen, so that the ladder 602 will not loosen, which plays a role of safety protection.
