A device for recovering and utilizing boiler condensate steam.

Abstract

This application provides a device for recovering and utilizing steam from boiler condensate drains, belonging to the field of boiler condensate drain technology. The device includes a boiler body, one end of which is connected to a condensate expansion container, and the other end of which is connected to a condensate tank. A recovery mechanism is provided on one side of the condensate expansion container, which stores demineralized water inside a raw material tank. The demineralized water flows through a first pipe into multiple sets of fifth pipes, and is then sprayed out inside the recovery device through atomizing nozzles. This demineralized water mixes and exchanges heat thoroughly with the exhaust steam input into the recovery device through the condensate tank and the condensate expansion container via second and third pipes. The condensate produced after this mixing and heat exchange solves the problem of existing boiler condensate drain devices lacking exhaust steam recovery and utilization mechanisms, resulting in exhaust steam being discharged into the atmosphere through the condensate tank vent, leading to significant steam loss.

Description

Technical Field

[0001] This application relates to the field of boiler condensate drainage, and more specifically, to a device for recovering and utilizing steam from boiler condensate drainage. Background Technology

[0002] Boiler condensate refers to the water formed by steam condensation in steam pipes and steam-using equipment that is automatically discharged through special devices (such as condensate expansion containers or condensate tanks). The condensate passes through the condensate expansion container, where the high-pressure condensate is reduced and expanded to lower the pressure of the condensate. The depressurized condensate then flows into the interior of the condensate tank.

[0003] However, the existing boiler condensate drain devices still have the following shortcomings during use: In the process of draining the existing boiler condensate drain devices, the exhaust steam generated by the boiler will flow into the interior of the drain tank along with the drain water. The existing boiler condensate drain devices are not equipped with exhaust steam recovery and utilization devices, which causes the exhaust steam to be discharged into the atmosphere through the drain tank vent. A large amount of exhaust steam is not recovered, resulting in steam loss. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a device for recovering and utilizing steam from boiler condensate drains, which aims to improve the problem that existing boiler condensate drain devices do not have a waste steam recovery and utilization device, resulting in waste steam being discharged into the atmosphere through the drain tank vent, with a large amount of waste steam not being recovered, causing steam loss.

[0005] This application provides a device for recovering and utilizing boiler condensate steam, including a boiler body, one end of which is connected to a condensate expansion container, one end of which is connected to a condensate tank, and a recovery mechanism for recovering exhaust steam is provided on one side of the condensate expansion container. The recycling mechanism includes a recycling device, the exhaust steam output end of the condensate expansion tank is connected to a second pipe, the other end of the second pipe is connected to the recycling device, and the exhaust steam output end of the condensate tank is connected to a third pipe. The recycling device is equipped with an adjustment mechanism inside.

[0006] In one specific implementation, a raw material tank is provided on one side of the boiler body, the output end of the raw material tank is connected to a first pipe, the other end of the first pipe is connected to multiple sets of fifth pipes, one end of the fifth pipe passes through a recovery device and is connected to an atomizing nozzle.

[0007] In the above process, the demineralized water can be stored inside the raw material tank. The demineralized water flows into multiple sets of fifth pipes through the first pipe and is then sprayed out inside the recovery device through atomizing nozzles. It is fully mixed and heat exchanged with the exhaust steam that is input into the recovery device through the condensate tank and condensate expansion tank through the second and third pipes. The condensate produced after the two are mixed and heat exchanged is condensed.

[0008] In one specific implementation, the output end of the recycling device is connected to a fourth pipe, and the other end of the fourth pipe is connected to a condensate tank.

[0009] In the above implementation process, the condensate in the recovery device can be transported to the interior of the condensate tank through the fourth pipeline. Then, the condensate recovered in the condensate tank is sent to the low-pressure deaerator by the matching condensate pump, so as to realize the recovery and utilization of exhaust steam. The condensate pump and the low-pressure deaerator are existing technologies and will not be described in detail here.

[0010] In one specific implementation, the adjustment mechanism includes a motor connected to the top of the recycling device, a first circular plate connected inside the recycling device, and the output shaft of the motor passing through the recycling device and the first circular plate and connected to a rotating component.

[0011] In the above implementation process, by setting up the motor, the output shaft of the motor can be controlled to rotate, thereby driving the rotating parts to rotate.

[0012] In one specific implementation, the rotating component is rotatably connected to the bottom of the first circular plate, and the bottom of the rotating component is connected to the second circular plate.

[0013] In the above implementation process, by setting up a rotating component, the second circular plate can be driven to rotate when the rotating component rotates at the bottom of the first circular plate.

[0014] In one specific implementation, a plurality of sliding grooves are formed through the top of the second circular plate.

[0015] In the above implementation process, by setting the sliding groove, the position of the atomizing nozzle can be adjusted when the second circular plate rotates, which can drive the atomizing nozzle to move back and forth.

[0016] In one specific implementation, the bottom of the first circular plate is connected to multiple sets of moving tracks, and the moving tracks are slidably connected to moving components.

[0017] In the above implementation process, by setting the moving track, the moving part can slide inside the moving track, and the moving part can only move back and forth in the horizontal direction of the moving track.

[0018] In one specific implementation, a slider is connected to the outer surface of the moving part, and the slider slides inside the sliding groove.

[0019] In the above implementation process, by setting the slider, when the second circular plate rotates, the slider can be driven to move inside the sliding groove. Since the slider is connected to the outer surface of the moving part, the slider can only move back and forth in the horizontal direction of the moving track.

[0020] In one specific implementation, the atomizing nozzle is connected to the other end of the slider.

[0021] In the above implementation process, by setting the atomizing nozzle, the sliding part can move the atomizing nozzle back and forth, thereby increasing the spraying area of ​​the atomizing nozzle and accelerating the heat exchange reaction between the demineralized water and the exhaust steam.

[0022] In one specific implementation, the fifth pipe penetrates the first circular plate, and the length of the fifth pipe is sufficient for the atomizing nozzle to move back and forth.

[0023] In the above implementation process, the fifth pipe ensures that the atomizing nozzle can always stably provide demineralized water to the atomizing nozzle as it moves back and forth inside the recovery device.

[0024] Compared with the prior art, the beneficial effects of this application are as follows: By setting up a recovery mechanism and a regulating mechanism, demineralized water can be stored inside the raw material tank. The demineralized water flows into multiple sets of fifth pipes through the first pipe, and then is sprayed out inside the recovery device through atomizing nozzles. It is fully mixed and heat-exchanged with the exhaust steam input into the recovery device through the condensate tank and condensate expansion tank through the second and third pipes. The condensate produced after the two mix and exchange heat is driven by a motor to rotate the second circular plate, which drives the atomizing nozzles to move back and forth, thereby increasing the spraying area of ​​the atomizing nozzles and accelerating the heat exchange reaction between the demineralized water and the exhaust steam. Then, the condensate in the recovery device is transported to the interior of the condensate tank through the fourth pipe, and the condensate recovered in the condensate tank is sent to the low-pressure deaerator by a matching condensate pump, realizing the recovery and utilization of exhaust steam. This solves the problem that the existing boiler condensate devices do not have exhaust steam recovery and utilization devices, resulting in exhaust steam being discharged into the atmosphere through the condensate tank vent, with a large amount of exhaust steam not being recovered, causing steam loss.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0029] Please see Figure 1 This application provides a device for recovering and utilizing steam from a boiler condensate, including a boiler body 1.

[0030] Please see Figure 1 and Figure 2 One end of the boiler body 1 is connected to a condensate expansion container 4, and one end of the condensate expansion container 4 is connected to a condensate tank 5. A recovery mechanism 2 for recovering exhaust steam is provided on one side of the condensate expansion container 4.

[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8The recycling mechanism 2 includes a recycling device 201. The exhaust steam output end of the condensate expansion tank 4 is connected to a second pipe 204. The other end of the second pipe 204 is connected to the recycling device 201. The exhaust steam output end of the condensate tank 5 is connected to a third pipe 205. An adjustment mechanism 3 is provided inside the recycling device 201.

[0032] In the specific setup, a raw material tank 202 is provided on one side of the boiler body 1. The output end of the raw material tank 202 is connected to a first pipe 203. The other end of the first pipe 203 is connected to multiple sets of fifth pipes 207. One end of the fifth pipe 207 passes through the recovery device 201 and is connected to an atomizing nozzle 208. The raw material tank 202 allows demineralized water to be stored inside. The demineralized water flows into the multiple sets of fifth pipes 207 through the first pipe 203 and is then sprayed out of the recovery device 201 through the atomizing nozzle 208. It mixes and exchanges heat fully with the exhaust steam input into the recovery device 201 through the condensate tank 5 and the condensate expansion container 4 through the second pipe 204 and the third pipe 205. The condensate produced after the two mix and exchange heat is then generated.

[0033] In the specific setup, the output end of the recovery device 201 is connected to a fourth pipe 206, and the other end of the fourth pipe 206 is connected to the condensate tank 5. Through the fourth pipe 206, the condensate in the recovery device 201 can be transported to the interior of the condensate tank 5. Then, a matching condensate pump is used to send the recovered condensate in the condensate tank 5 to the low-pressure deaerator, realizing the recovery and utilization of exhaust steam. The condensate pump and the low-pressure deaerator are existing technologies and will not be described in detail here.

[0034] In a specific configuration, the adjustment mechanism 3 includes a motor 301, which is connected to the top of the recycling device 201. The recycling device 201 is internally connected to a first circular plate 302. The output shaft of the motor 301 passes through the recycling device 201 and the first circular plate 302 and is connected to a rotating component 304. By configuring the motor 301, the output shaft of the motor 301 can be controlled to rotate, thereby driving the rotating component 304 to rotate.

[0035] In a specific configuration, the rotating component 304 is rotatably connected to the bottom of the first circular plate 302, and the bottom of the rotating component 304 is connected to the second circular plate 303. By configuring the rotating component 304, the second circular plate 303 can be driven to rotate when the rotating component 304 rotates at the bottom of the first circular plate 302.

[0036] In a specific configuration, multiple sliding grooves 308 are provided through the top of the second circular plate 303. The sliding grooves 308 allow the position of the atomizing nozzle 208 to be adjusted when the second circular plate 303 rotates, thus enabling the atomizing nozzle 208 to move back and forth.

[0037] In a specific configuration, the bottom of the first circular plate 302 is connected to multiple sets of moving rails 305, and a moving part 306 is slidably connected inside the moving rails 305. The moving part 306 can slide inside the moving rails 305, and can only move back and forth in the horizontal direction of the moving rails 305.

[0038] In a specific configuration, a slider 307 is connected to the outer surface of the movable member 306. The slider 307 slides inside the sliding groove 308. By setting the slider 307, when the second circular plate 303 rotates, the slider 307 can be driven to move inside the sliding groove 308. Since the slider 307 is connected to the outer surface of the movable member 306, the slider 307 can only move back and forth in the horizontal direction of the moving track 305.

[0039] In a specific configuration, the atomizing nozzle 208 is connected to the other end of the sliding member 307. By configuring the atomizing nozzle 208, the sliding member 307 can move the atomizing nozzle 208 back and forth, thereby increasing the spraying area of ​​the atomizing nozzle 208 and accelerating the heat exchange reaction between the demineralized water and the exhaust steam.

[0040] In the specific configuration, the fifth pipe 207 passes through the first circular plate 302, and the length of the fifth pipe 207 is sufficient for the atomizing nozzle 208 to move back and forth. The configuration of the fifth pipe 207 ensures that when the atomizing nozzle 208 moves back and forth inside the recovery device 201, the fifth pipe 207 can always stably provide demineralized water to the atomizing nozzle 208.

[0041] The working principle of this boiler condensate steam recovery and utilization device is as follows: When using the device, demineralized water is stored inside the raw material tank 202. The demineralized water flows through the first pipe 203 and dispersed into multiple sets of fifth pipes 207. Then, through atomizing nozzles 208, the demineralized water is sprayed into the recovery device 201, where it is thoroughly mixed and heat-exchanged with the exhaust steam input into the recovery device 201 through the condensate tank 5 and the condensate expansion container 4 via the second pipe 204 and the third pipe 205. The condensate produced after the two mixtures heat exchange is further processed by a motor 301 that drives a rotating component 304 to rotate, causing the second circular plate 303 to rotate. This, in turn, causes the sliding component 307 to slide within the sliding groove 308. Since the sliding member 307 is connected to the outer surface of the moving member 306, the sliding member 307 can only move back and forth in the horizontal direction of the moving track 305, which can drive the atomizing nozzle 208 to move back and forth, thereby increasing the spraying area of ​​the atomizing nozzle 208, accelerating the heat exchange reaction between the demineralized water and the exhaust steam, and then the condensate in the recovery device 201 is transported to the interior of the condensate tank 5 through the fourth pipe 206, and then the condensate recovered in the condensate tank 5 is sent to the low-pressure deaerator by the matching condensate pump, so as to realize the recovery and utilization of exhaust steam, thereby solving the problem that the existing boiler condensate device does not have an exhaust steam recovery and utilization device, which causes exhaust steam to be discharged into the atmosphere through the vent of the condensate tank 5, resulting in a large amount of exhaust steam not being recovered and causing steam loss.

[0042] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
