As shown in fig. 1-4, the embodiment of the utility model discloses a pipe joint for desulfurization waste water treatment, this pipe joint for desulfurization waste water treatment can be applied to among the desulfurization system, and it can regard as a part of discharge line, and this discharge line can communicate absorption tower and processing apparatus for the exhaust desulfurization waste water of absorption tower can be discharged to processing apparatus. The pipe joint for treating desulfurization waste water may specifically include a connection pipe 110, a tap pipe 120, a draft tube 130, a sealing end cap 140, a mounting rod 150, and a scraper 160.
The number of the draft tubes 130 is at least two, for example, the draft tubes 130 may be provided in two, three or more. The connection pipe 110, the tap 120, and the at least two draft tubes 130 are communicated such that the desulfurization wastewater can flow between the connection pipe 110, the tap 120, and the draft tube 130. The connection pipe 110 and the draft pipe 130 are respectively installed at both sides of the connection pipe 120, and both ends of the connection pipe 120 are respectively provided with a sealing end cap 140. The sealing end caps 140 herein can seal both ends of the tap tube 120, and prevent the desulfurization waste water from leaking from both ends of the tap tube 120.
The mounting bar 150 is movably coupled to the end cap 140 such that the mounting bar 150 is movable relative to the end cap 140. Specifically, the mounting rod 150 may be connected to only one of the end caps 140, or may be connected to both end caps 140. The mounting rod 150 may have one end positioned outside the tap 120 and the other end extending into the tap 120. Since the mounting rod 150 is movably connected to the cap 140, in order to prevent the desulfurization waste water from flowing out through the gap between the mounting rod 150 and the cap 140, a sealing member may be provided inside the cap 140, the mounting rod 150 may be movable with respect to the sealing member, and the sealing member may seal the gap between the mounting rod 150 and the cap 140, preventing the waste water from flowing out.

In the pipe joint for treating desulfurization waste water, the installation rod 150 is provided with the scraper 160, and the installation rod 150 can move, so that the scraper 160 can be driven to move relative to the distribution pipe 120. When the inner wall of the tap 120 has a large amount of impurities, the scraper 160 can be driven by the mounting rod 150 to move, so that the impurities attached to the inner wall of the tap 120 can be scraped off, and the impurities can be further cleaned, thereby preventing the tap 120 from being blocked.
In a specific embodiment, the mounting rod 150 can move, rotate or move and rotate simultaneously with respect to the end cap 140, in order to simplify the structure of the pipe joint for treating desulfurization wastewater and ensure the sealing performance between the mounting rod 150 and the end cap 140, optionally, the mounting rod 150 is rotatably connected with the end cap 140, and the rotation axis of the mounting rod 150 is the self axis. When the mounting bar 150 is rotated about its axis, the scraper 160 is also rotated about the axis of the mounting bar 150, thereby scraping off impurities attached to the inner wall of the tap 120.
In a further embodiment, a filter housing 170 is provided in the connection pipe 110, and the filter housing 170 can be securely installed in the connection pipe 110. The connection pipe 110 has an inlet at one end and an outlet at the other end, and the inlet is communicated with the outlet through a filter housing 170. That is to say, desulfurization waste water need pass through filter housing 170 after getting into from the import and just can flow out from the export, and in this process, the impurity of the bigger granule that carries in the desulfurization waste water can be strained by filter housing 170 to reduce the impurity in the desulfurization waste water. Alternatively, the filter cover 170 may be taken out of the connection pipe 110, and when the foreign substances filtered by the filter cover 170 reach a certain amount, the filter cover 170 may be detached and the filter cover 170 may be washed, so that the filter cover 170 may be used repeatedly for a long time.
As described above, the sealing caps 140 are respectively installed at both ends of the tap tube 120, and in this case, the sealing caps 140 include the first cap 141 and the second cap 142, the first cap 141 is disposed at one end of the tap tube 120, and the second cap 142 is disposed at the other end of the tap tube 120.
