[0029] An embodiment of this application provides a boiler tail gas monitoring water-blocking device, which is installed on a boiler tail gas pipeline 010 and can block impurities and water droplets in the tail gas.
[0030] As Figure 1 and Figure 2 shown, the boiler tail gas monitoring water-blocking device includes an installation pipe 100 and three sealing plates 200. Among them, the installation pipe 100 is a structure for installing and supporting other components and is also a structure for connecting to the boiler tail gas pipeline 010, and the sealing plate 200 is a structure for blocking the installation opening 120 of the installation pipe 100.
[0031] As Figure 3 shown, installation flanges 110 are provided at both ends of the installation pipe 100. The installation flanges 110 are used to connect to the boiler tail gas pipeline 010, thereby realizing the installation of the entire device onto the boiler tail gas pipeline 010.
[0032] As Figure 3As shown, the installation pipe 100 is provided with three installation ports 120 and three installation ring plates 130. The three installation ports 120 are spaced along the axial direction of the installation pipe 100, and the three installation ring plates 130 are correspondingly arranged at the three installation ports 120, so that other components can be installed on the installation ring plates 130 from the installation ports 120, which is convenient for installation.
[0033] As Figure 2 shown, a first filter plate 140, a second filter plate 150 and a waterproof and breathable membrane 160 are successively installed on the three installation ring plates 130 along the axial direction of the installation pipe 100. The pore size of the first filter plate 140 is larger than that of the second filter plate 150. The first filter plate 140 conducts the first filtration of impurities, and the second filter plate 150 can conduct the second filtration of impurities. Through two filtrations, the filtration effect is ensured.
[0034] The waterproof and breathable membrane 160 is a new type of polymer waterproof material that allows gas to pass through and blocks water droplets from passing through, thereby achieving the function of waterproofing.
[0035] The gas monitoring device is installed in the boiler tail gas pipeline 010. When installing the installation pipe 100, the waterproof and breathable membrane 160 should be close to the gas monitoring device, so that the tail gas passes through the first filter plate 140, the second filter plate 150 and the waterproof and breathable membrane 160 in sequence, and finally enters the gas monitoring device to realize the monitoring of the tail gas.
[0036] As Figure 2 shown, the first ends of the three sealing plates 200 are correspondingly rotatably connected to the first ends of the three installation ports 120, and the second ends of the three sealing plates 200 are correspondingly detachably connected to the second ends of the three installation ports 120. A sealing ring is provided between each sealing plate 200 and the installation port 120, which is convenient for opening and closing the installation port 120, and realizes sealing through the sealing ring when closed to avoid gas leakage.
[0037] During use, the installation pipe 100 is installed on the boiler tail gas pipeline 010 through the installation flange 110, and the tail gas can pass through the first filter plate 140, the second filter plate 150 and the waterproof and breathable membrane 160 in sequence. The tail gas monitoring device is installed in the boiler tail gas pipeline 010 on the side close to the waterproof and breathable membrane 160. The impurities contained in the tail gas can be filtered twice through the first filter plate 140 and the second filter plate 150, and the water droplets in the tail gas are blocked by the waterproof and breathable membrane 160, thereby reducing the entry of impurities and water droplets into the subsequent tail gas monitoring device.
[0038] Compared with the prior art, the boiler tail gas monitoring water-blocking device filters and blocks impurities and water droplets by setting the first filter plate 140, the second filter plate 150 and the waterproof breathable membrane 160, thereby reducing the entry of impurities and water droplets into the subsequent tail gas monitoring device, reducing the impact on the monitoring results, ensuring the accuracy of the monitoring results, and at the same time reducing the damage of the tail gas monitoring device and extending its service life.
[0039] In some embodiments, as Figure 3 shown, the boiler tail gas monitoring water-blocking device further includes a condensing pipe 300. The condensing pipe 300 is located inside the installation pipe 100, penetrates through the installation pipe 100 and is communicated with a cooling water pipe (not shown in the figure). When the temperature of the tail gas is relatively high, the tail gas also contains some water vapor. The water vapor in the tail gas can be liquefied into water droplets through the condensing pipe 300, and the waterproof breathable membrane 160 can block the entry of the water droplets, thereby realizing the blockage of the water vapor in the tail gas from entering and reducing the impact on the monitoring results.
[0040] In some embodiments, as Figure 3 shown, the condensing pipe 300 is located between the second filter plate 150 and the waterproof breathable membrane 160. That is to say, the water vapor is liquefied before reaching the waterproof breathable membrane 160, and the blocking effect is better.
[0041] In some embodiments, as Figure 3 , Figure 4 and Figure 5 shown, the installation opening 120 is a semi-circular opening, and the sealing plate 200 is a semi-circular plate, so that the maximum dimension of the installation opening 120 is the same as the inner diameter of the installation pipe 100, and the components can be conveniently installed into the installation pipe 100. Two threaded shafts 131 are provided on the installation ring plate 130. The two threaded shafts 131 are located at both ends of the semi-circular opening. The first filter plate 140, the second filter plate 150 and the waterproof breathable membrane 160 are all provided with installation holes 141. The installation holes 141 cooperate with the threaded shafts 131 and are fixed by nuts to realize the installation of the first filter plate 140, the second filter plate 150 and the waterproof breathable membrane 160. Moreover, the threaded shafts 131 are arranged at both ends of the semi-circular opening, which is convenient for operation.
[0042] In some embodiments, the first end of the sealing plate 200 is connected to the first end of the installation opening 120 through a hinge (not shown in the figure). A connecting plate 210 is provided at the second end of the sealing plate 200. The connecting plate 210 is connected to the second end of the installation opening 120 through bolts, realizing the rotational connection of the first end of the sealing plate 200 and the detachable connection of the second section. The connecting plate 210 can have a certain arc so as to fit with the outer circumferential wall of the installation pipe 100, and the installation is more firm.
[0043] In some embodiments, as Figure 3As shown, a plurality of water blocking ring grooves 111 are provided on the end face of the mounting flange 110 close to the waterproof and breathable membrane 160, and the plurality of water blocking ring grooves 111 are all coaxial with the mounting flange 110. During installation, a gasket is provided between the mounting flange 110 and the flange of the boiler tail gas pipeline 010 to achieve sealing and avoid gas leakage. However, external water vapor may gradually penetrate into the gasket. By providing the water blocking ring grooves 111, the path of water vapor entry can be extended, reducing the possibility of water vapor entering the installation pipe 100, thereby reducing the impact on the tail gas monitoring results of the tail gas monitoring device. The mounting flange 110 at the other end of the installation pipe 100 does not need to be provided with water blocking ring grooves 111. Even if water droplets enter from here, they will be blocked by the waterproof and breathable membrane 160 and will not enter the subsequent tail gas monitoring device.
[0044] In some embodiments, water absorbing strips (not shown in the figure) are provided in the water blocking ring grooves 111. The water absorbing strips can absorb water vapor, further reducing the possibility of water vapor entering the installation pipe 100 and reducing the impact on the tail gas monitoring results. The water absorbing strips can generally be made of sponge or fiber, etc., as long as they can play a role in absorbing water.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
