Description

Technical Field

[0001] This utility model relates to the field of steam emission equipment technology, and in particular to a steam waste gas emission system. Background Technology

[0002] Steam is typically transported to the required factory (or processing point) via a pipeline system. During production, steam is generally produced at a rate exceeding demand to ensure that needs are met. Therefore, a vent pipe is usually installed at the end of the pipeline system to remove excess steam. This vent pipe typically directs the excess steam into a drainage ditch, where it condenses into water and drains away without further treatment – ​​a very convenient process. However, in some situations, such as heavy rain, the drainage ditch may experience high water levels. This high water level could submerge the end of the vent pipe, creating a water seal and obstructing the discharge of excess steam. In severe cases, this could lead to a sudden increase in pressure within the pipeline system, posing a safety hazard. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a steam waste gas discharge system, which solves the problem that rising water levels in trenches may form a water seal on the waste gas pipe, leading to poor waste gas discharge and potential dangers.

[0004] According to an embodiment of this utility model, a steam waste gas emission system includes a horizontally arranged waste gas pipe and a trench located below the waste gas pipe. The waste gas pipe is connected to a first exhaust pipe extending into the trench and a second exhaust pipe extending above the waste gas pipe. A floating plate is installed in the trench below the first exhaust pipe, and a valve plate is connected to the floating plate. The valve plate moves up and down with the floating plate to close or open the first exhaust pipe. The second exhaust pipe extends vertically, and a floating opening and closing component is installed at its upper end to control the opening or closing of the second exhaust pipe. The first and second exhaust pipes are connected to the end of the waste gas pipe. Under normal circumstances, the first exhaust pipe smoothly discharges waste gas into the trench. When the water level in the trench rises and causes the first exhaust pipe to be water-sealed, the internal air pressure of the second exhaust pipe rises and pushes the opening and closing component upward, causing the second exhaust pipe to open for standby exhaust, thereby maintaining normal exhaust and avoiding a sudden increase in air pressure in the pipeline system. This solves the problem in the prior art where rising water levels in the trench may form a water seal on the waste gas pipe, leading to poor waste gas discharge and potential danger.

[0005] Furthermore, the upper end of the trench is covered with a cover plate, and a first guide rod extending downward into the trench is detachably connected to the cover plate. A first sliding hole is provided on the floating plate for the first guide rod to pass through.

[0006] Furthermore, an installation plate located below the first exhaust pipe is fixedly connected to one inner wall of the trench. A second guide rod extending downward is fixedly connected to the installation plate, and a second sliding hole for the second guide rod to pass through is also provided on the floating plate.

[0007] Furthermore, the lower end of the second guide rod is also threadedly connected to a limiting ring located below the upper floating plate.

[0008] Furthermore, the end of the first exhaust pipe located in the trench is also fixedly connected to a first perforated plate, which has several first perforations. The valve plate can completely cover or not cover all the first perforations on the side facing the first exhaust pipe.

[0009] Furthermore, the floating opening and closing assembly includes a second orifice plate fixedly connected inside the second exhaust pipe. The second orifice plate is provided with a third sliding hole located at its center and a plurality of second through holes surrounding the third sliding hole. The floating opening and closing assembly also includes a connecting rod that slides through the third sliding hole and a counterweight and a cap connected to both ends of the connecting rod. The counterweight is located below the second orifice plate, and the cap can engage with the end of the second exhaust pipe or be located above the end of the second exhaust pipe.

[0010] Furthermore, the lower end of the end cap is shaped like an inverted frustum that can enter and exit the end of the second exhaust pipe, and the upper end is fixedly connected to a stop plate that can abut against the end of the second exhaust pipe.

[0011] Furthermore, the counterweight is cylindrical with a diameter greater than the inner diameter of the third sliding hole, and all the second perforations are located outside the counterweight.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting up a first exhaust pipe and a second exhaust pipe connected to the residual gas pipe and located inside and above the trench respectively, when the water level in the trench rises and causes the first exhaust pipe to be water-sealed, the increased air pressure inside the second exhaust pipe will push the amplitude opening and closing component upward, causing the second exhaust pipe to open for backup exhaust, thereby maintaining normal exhaust and avoiding a sudden increase in air pressure in the pipeline system. This solves the problem in the prior art where rising water levels in the trench may form a water seal on the residual gas pipe, leading to poor exhaust of residual gas and causing danger.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] In an exemplary implementation, such as Figure 1 , 2 As shown, this embodiment provides a steam exhaust system, which includes a horizontally arranged exhaust pipe 1 and a trench 2 located below the exhaust pipe 1. The exhaust pipe 1 is connected to a first exhaust pipe 3 extending into the trench 2 and a second exhaust pipe 4 extending above the exhaust pipe 1. That is, the outlet of the first exhaust pipe 3 is located inside the trench 2, and the outlet of the second exhaust pipe 4 is located outside the trench 2. A floating plate 5 is arranged inside the trench 2, located below the first exhaust pipe 3. A valve plate 6 is connected to the floating plate 5, and the valve plate 6 can close or open the first exhaust pipe 3 by moving up and down with the floating plate 5. More specifically, an opening is provided on the first exhaust pipe 3, and initially the upper end of the valve plate 6 is located at the opening. Inside, the first exhaust pipe 3 is fully open. When the water level in the ditch 2 rises, the upper float 5 floats upward, driving the valve plate 6 upward and gradually closing the first exhaust pipe 3. The second exhaust pipe 4 extends vertically and has a floating opening and closing component installed at its upper end to control the opening or closing of the second exhaust pipe 4. When the first exhaust pipe 3 is closed, the air pressure in the second exhaust pipe 4 will increase, thereby pushing upward to open the floating opening and closing component, and the residual gas will be discharged through the second exhaust pipe 4. This avoids the sudden increase in air pressure in the pipeline system and solves the problem in the prior art that the rising water level in the ditch 2 may form a water seal on the residual gas pipe 1, causing the residual gas to be discharged poorly and causing danger.

[0021] like Figure 1 , 2As shown, in a further embodiment, the upper end of the trench 2 is covered with a cover plate 7. A first guide rod 8 extending downward into the trench 2 is detachably connected to the cover plate 7. The floating plate 5 is provided with a first sliding hole through which the first guide rod 8 passes. The first guide rod 8 provides guidance for the floating plate 5 to float up and down, enabling the floating plate 5 to float up and down more smoothly. More specifically, the cover plate 7 can be lifted up, and the first guide rod 8 can also be lifted up at the same time. The first guide rod 8 and the cover plate 7 can be threaded together. After being lifted up, it can be disassembled, which facilitates maintenance inside the trench 2. Furthermore, A mounting plate 9 located below the first exhaust pipe 3 is fixedly connected to the inner wall of one side of the trench 2. A second guide rod 10 extending downward is fixedly connected to the mounting plate 9. A second sliding hole for the second guide rod 10 to pass through is also provided on the upper floating plate 5. The second guide rod 10, similar to the first guide rod 8, also provides guidance for the upper floating plate 5 to float up and down. At the same time, a limiting ring 11 located below the upper floating plate 5 is threadedly connected to the lower end of the second guide rod 10. The limiting ring 11 prevents the upper floating plate 5 from disengaging from the second guide rod 10 downward, thereby ensuring that the upper floating plate 5 can remain stable when the water in the trench 2 does not come into contact with it.

[0022] like Figure 1 , 2As shown, in a further embodiment, the first exhaust pipe 3 extends laterally, and a first perforated plate 12 is fixedly installed inside its end. The first perforated plate 12 has several first through holes 13 arranged on it, and the valve plate 6 can completely or partially cover the side of the first through holes 13 facing the inside of the first exhaust pipe 3. The first through holes 13 serve to connect the inside and outside of the first exhaust pipe 3. When the valve plate 6 covers the first through holes 13, it isolates the first exhaust pipe 3. Water may leak into the first exhaust pipe 3, but it will not enter the second exhaust pipe 4, thus preventing moisture from entering the second exhaust pipe 4. Furthermore, the floating opening and closing assembly includes a first... The second perforated plate 14 has a third sliding hole at its center and several second through holes 15 surrounding the third sliding hole. The floating opening and closing assembly also includes a connecting rod 16 that slides through the third sliding hole, a counterweight 17 connected to both ends of the connecting rod 16, and a cap 18. The counterweight 17 is located below the second perforated plate 14, and the cap 18 can engage with or be located above the end of the second exhaust pipe 4. The second perforated plate 14 and the second through holes 15 thereon serve a similar function of communication. At the same time, the second perforated plate 14 also restricts the counterweight 17 from moving upward, thereby allowing the cap 18 to reach its highest position. Specifically, the counterweight 17 is cylindrical with a diameter larger than the inner diameter of the third sliding hole, and all the second through holes 15 are located outside the counterweight 17. This ensures that the counterweight 17 does not pass through the second perforated plate 14 to the top. When the counterweight 17 abuts against the second perforated plate 14, all the second through holes 15 can function normally. At this time, the lower end of the end cap 18 is an inverted frustum shape, with a gap between it and the inner wall of the second exhaust pipe 4. Excess gas is discharged outward through the gap, thus achieving exhaust. In other words, the lower end of the end cap 18 is an inverted frustum shape that can enter and exit the end of the second exhaust pipe 4. Simultaneously, the upper end of the end cap 18 is fixedly connected to a stop plate that abuts against the end of the second exhaust pipe 4. 19. When the counterweight 17 is at its lowest point (i.e., when exhaust is being discharged through the first exhaust pipe 3), the abutment 19 abuts against the end face of the second exhaust pipe 4, thereby closing the second exhaust pipe 4. (The counterweight 17, connecting rod 16, and end cap 18 together have a large weight, requiring greater atmospheric pressure after the first exhaust pipe 3 is closed to push them upward and open the second exhaust pipe 4. At the same time, a sealing structure can be provided between the end faces of the abutment 19 and the second exhaust pipe 4 to prevent leakage when the abutment 19 and the second exhaust pipe 4 are closed.) Furthermore, the inverted frustum-shaped end cap 18 structure can enter the second exhaust pipe 4 more smoothly when it is downward.
