Abstract
Description
Technical Field
[0001] This utility model relates to the field of boiler technology, and more specifically, to a boiler chimney condensate discharge device and a boiler flue gas assembly. Background Technology
[0002] The unique geological conditions of the Qarhan Salt Lake area, namely the prevalent saline soil, pose a severe challenge to the winter operation and maintenance of steam boilers. In this region, the roads and factory floors are entirely paved with salt. This saline soil is extremely sensitive to freshwater; any infiltration can cause the dissolution of underground salts, leading to soil structure damage and even foundation collapse. This poses a serious safety hazard to equipment fixed to the ground, such as steam boilers. During winter heating, the steam boilers, as the primary heat source, continuously produce condensate in their chimneys due to steam condensation. This condensate is discharged through drainage channels in the chimney foundation; however, due to the low winter temperatures, the condensate easily freezes in the drainage channels, preventing timely discharge. Utility Model Content
[0003] The main purpose of this utility model is to provide a boiler chimney condensate discharge device and a boiler exhaust assembly, which can solve the problem that when using the existing boiler chimney condensate discharge structure to discharge condensate, the condensate flowing out is prone to freezing in the drainage channel, resulting in the condensate not being discharged in time.

[0005] Furthermore, the angle between the installation channel and the horizontal plane ranges from 10° to 30°.

One end of the first transition section is connected to a drain pipe, and the other end of the first transition section is connected to the second transition section. The liquid outlet end of the second transition section is configured to connect to the boiler room trench.
[0008] Furthermore, the first transition segment extends horizontally, and the second transition segment extends vertically.
[0009] Furthermore, a second heat-insulating and anti-freezing structure is provided on the outer periphery of the transition structure.
[0010] Furthermore, the installation channel extends from the top of the installation base to the side wall of the installation base and penetrates through it.

[0020] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.
[0021] like Figure 1As shown, this utility model provides a boiler chimney condensate discharge device, which includes: an installation base 10 for installing the chimney body 20, the installation base 10 having an installation channel, both ends of the installation channel being configured to communicate with the outside, and the installation channel being inclined relative to the horizontal plane; and a drainage structure installed in the installation channel and adapted to the installation channel, the drainage structure including a drain pipe 30 and a first heat insulation and antifreeze structure disposed on the outer periphery of the drain pipe 30.
[0022] In this embodiment, one end of the installation channel is connected to the inner cavity of the chimney body 20, and the other end is connected to the outside. The installation channel is inclined relative to the horizontal plane, and the installation channel is inclined from the top of the installation base 10 to the bottom of the installation base 10. The drainage structure is installed in the installation channel and adapted to the installation channel. Therefore, the drain pipe 30 is also inclined relative to the horizontal plane, and the drain pipe 30 is inclined downward from the top of the installation base 10 to the bottom of the installation base 10. In this way, the effect of gravity ensures that the condensate can flow more smoothly along the inclined drain pipe 30 during the discharge process. The inclined drain pipe 30 can accelerate the discharge speed of condensate. Even in the low temperature environment of winter, it can effectively prevent the condensate from staying in the drain pipe 30 for too long and freezing into ice. In addition, the outer periphery of the drain pipe 30 is provided with a first heat insulation and antifreeze structure. The first heat insulation and antifreeze structure can effectively reduce the heat exchange inside and outside the drain pipe 30, prevent the condensate from freezing during the discharge process, ensure its flow state, and thus ensure that the condensate can be discharged in a timely and smooth manner even in winter.
[0023] In one embodiment, the first thermal insulation and antifreeze structure can be rock wool, glass wool, polyurethane foam, etc., which have good thermal insulation properties, or it can be an electric heating tape.
[0024] In one embodiment, the drain pipe 30 is a steel pipe.
[0025] In one embodiment of this utility model, the angle between the installation channel and the horizontal plane ranges from 10° to 30°.
[0026] In this embodiment, the angle between the installation channel and the horizontal plane ranges from 10° to 30°. Since the drainage structure is installed inside and adapted to the installation channel, the angle between the drain pipe 30 and the horizontal plane also ranges from 10° to 30°. The inclined drain pipe 30, on the one hand, accelerates the flow rate of condensate, reduces the time for condensate to cool and solidify within the drain pipe 30, thereby reducing the possibility of condensate freezing and clogging the drain pipe 30, and ensuring continuous and smooth discharge of condensate. On the other hand, it also reduces the accumulation of impurities such as rust within the drain pipe 30, thus extending the service life of the drainage device.
[0027] like Figure 1 As shown, in one embodiment of the present invention, the drainage structure further includes a transition structure 40, the liquid outlet end of the drain pipe 30 extends out of the installation channel and communicates with the transition structure 40, and the liquid outlet end of the transition structure 40 is configured to communicate with the boiler room trench 50.
[0028] In this embodiment, the liquid outlet of the transfer structure 40 is connected to the boiler room trench 50 to discharge condensate into the boiler room trench 50. The boiler room trench 50 is connected to the sewer well 70, so the condensate is eventually discharged into the sewer well 70. This reduces the impact on the surrounding environment. Since the installation foundation 10 is made of saline soil, the above arrangement also avoids the problem of the installation foundation 10 collapsing due to the saline soil dissolving when the condensate is directly discharged to the ground.
[0029] In one embodiment, the adapter structure 40 is an elbow with the drain end of the elbow facing the boiler room trench 50, which can prevent condensate from splashing onto the ground, scalding workers, or contaminating the ground.
[0030] like Figure 1 As shown, in one embodiment of the present invention, the adapter structure 40 includes a first adapter section 41 and a second adapter section 42 arranged at an angle. One end of the first adapter section 41 is connected to the drain pipe 30, and the other end of the first adapter section 41 is connected to the second adapter section 42. The liquid outlet end of the second adapter section 42 is configured to be connected to the boiler room trench 50.
[0031] In this embodiment, the first transition section 41 and the second transition section 42 are arranged at an angle. On the one hand, the transition structure 40 can change the discharge direction of the condensate, ensuring that the condensate can be smoothly discharged to the boiler room trench 50. On the other hand, it can reduce the direct impact force when the condensate flows to the boiler room trench 50, avoid the high-speed flowing condensate from directly impacting the inner wall or bottom of the boiler room trench 50, and reduce the wear on the boiler room trench 50.
[0032] like Figure 1 As shown, in one embodiment of the present invention, the first transition segment 41 extends in the horizontal direction and the second transition segment 42 extends in the vertical direction.
[0033] In this embodiment, one end of the horizontally extending first transition section 41 is connected to the drain pipe 30, and the other end of the first transition section 41 passes through the boiler room wall 60 and is connected to the second transition section 42. The drain end of the vertically extending second transition section 42 faces the boiler room trench 50 to prevent the discharged condensate from splashing onto the ground.
[0034] In one embodiment of this utility model, a second heat-insulating and anti-freezing structure is provided on the outer periphery of the adapter structure 40.
[0035] The above settings can effectively reduce the temperature difference between the inside and outside of the adapter structure 40, and prevent condensate from freezing and clogging the adapter structure 40 in a low-temperature environment.
[0036] In one embodiment, the second thermal insulation and antifreeze structure can be rock wool, glass wool, polyurethane foam, etc., which have good thermal insulation properties.
[0037] like Figure 1 As shown, in one embodiment of the present invention, the mounting channel extends from the top of the mounting base 10 to the side wall of the mounting base 10 and penetrates through it.
[0038] In this embodiment, the chimney body 20 is installed on top of the mounting base 10, which serves as the bottom of the chimney body 20. An installation channel extends from the top of the mounting base 10 through its side wall; one end of the channel penetrates the top of the base and communicates with the inner cavity of the chimney body 20, while the other end penetrates the side wall and communicates with the outside. The outlet end of the drain pipe 30 extends out of the installation channel. Since the mounting base 10 is made of saline soil, this design prevents condensate from entering the installation channel after being discharged from the drain pipe 30, thus avoiding the dissolution of the saline soil and potential partial collapse of the mounting base 10.
[0039] like Figure 1 As shown, this utility model also provides a boiler flue gas assembly, including: a chimney body 20; as described above, the boiler chimney condensate discharge device, wherein the chimney body 20 is installed on the top of the mounting base 10, and the inner cavity of the chimney body 20 is connected to the drain pipe 30.
[0040] In this embodiment, the boiler chimney condensate discharge device of the boiler flue gas assembly has all the technical solutions and effects of the above-mentioned boiler chimney condensate discharge device, which will not be repeated here.
[0041] like Figure 1 As shown, in one embodiment of the present invention, a sampling port 21 is provided on the chimney body 20.
[0042] In this embodiment, the sampling port 21 allows operators to collect samples of chimney emissions at any time to detect parameters such as chemical composition, temperature, and pressure. This helps to promptly detect any abnormalities in the emissions, such as changes in the content of rust, salt, and harmful substances, thereby enabling rapid adjustments to the boiler's operating status to ensure that emissions meet safety standards.
[0043] like Figure 1 As shown, in one embodiment of the present invention, a top cover 22 is provided on the top of the chimney body 20.
[0044] In this embodiment, the top cover 22 can prevent rainwater from entering the inner cavity of the chimney body 20 and mixing with condensate, thus increasing the complexity of emission treatment. It can also prevent rainwater from eroding the internal structure of the chimney body 20, thereby extending the service life of the chimney body 20.
[0045] like Figure 1 As shown, in one embodiment of the present invention, a manhole 23 is provided at the bottom of the chimney body 20.
[0046] In this embodiment, the manhole 23 provides an access point for the operator to enter the inner cavity of the chimney body 20. When there is a lot of rust in the inner cavity of the chimney body 20 that blocks the drain pipe 30, the manhole 23 can be opened for manual unblocking to remove the rust in time and ensure the unobstructed flow of the drain pipe 30.
[0047] Currently, the foundations of the steam boilers used for winter heating in the mining area are surrounded by saline soil. This type of soil is extremely susceptible to contamination by fresh water. Under normal circumstances, the steam condensate discharge from the boiler chimney is normal. However, due to the small diameter of the discharge pipe, the inner wall of the chimney turns into water after the steam condenses. The chimney's inner wall experiences prolonged switching between high and low temperatures, resulting in a large amount of rust. The rust flows along with the condensate to the drain outlet, which becomes blocked, preventing the condensate from draining in time. As a result, the water level at the bottom of the chimney rises continuously, eventually causing the condensate to flow out from the manhole. The condensate collects near the chimney, and due to the low winter temperatures in the mining area, the flowing condensate freezes quickly. This not only affects the appearance of the plant but also, as the spring temperatures gradually warm up, the ice melts and slowly seeps into the ground, dissolving the salinity in the chimney foundation. This can lead to the collapse of the chimney foundation, causing the chimney to tilt and creating a safety hazard.
[0048] To address the aforementioned issues, in one embodiment, the drain pipe 30 of this application is a straight pipe, resulting in a straight drainage path. Compared to existing drainage structures, this not only reduces the use of bends and ensures smooth condensate flow but also shortens the condensate flow distance, reducing the likelihood of condensate freezing in extreme weather. Furthermore, because the drain pipe 30 is angled and straight, even if it becomes blocked, it can be quickly cleared through the manhole 23, ensuring timely drainage of condensate. This eliminates the need for replacement and complex maintenance, reducing maintenance costs and avoiding construction waste, thus protecting the mining area's ecological environment.
[0049] The boiler chimney exhaust device of this application can be modified based on the existing boiler chimney exhaust structure. The specific process is as follows: First, open the manhole and clean the rust and other debris at the bottom of the chimney body. Then, weld a steel plate around the bottom of the chimney body to seal the original drainage hole on the installation foundation, ensuring that condensate does not drain from the original drainage hole. Next, dig an installation channel on the installation foundation, making the angle between the installation channel and the horizontal plane within the range of 10° to 30°, and connecting one end of the installation channel to the inner cavity of the chimney body, and the other end of the installation channel to the outside, with the liquid outlet end of the installation channel facing the side where the boiler room wall 60 is located. Then, open a through hole on the boiler room wall 60. Next, install the drain pipe 30 with the first heat insulation and antifreeze structure on the outer periphery into the installation channel. Finally, connect one end of the transition structure 40 through the above-mentioned through hole to the drain pipe 30.
[0050] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: an installation foundation and a drainage structure are provided. The drainage structure includes a drainage pipe, and the outer periphery of the drainage pipe is provided with a heat insulation and antifreeze structure. The heat insulation and antifreeze structure can effectively reduce the heat exchange inside and outside the drainage pipe, prevent the condensate from freezing during the discharge process, and ensure its flow state, thereby ensuring that the condensate can be discharged smoothly and in a timely manner even in winter.
