The equipment is suitable for waste incineration plants, landfills and other fields.

[0003] The existing water distribution device is very prone to clogging due to the long-term accumulation of sludge at the bottom, which causes the water flow rate to decrease year by year. If it is not handled in time, it will affect the decline in processing volume, or even cause production suspension and overhaul. When the existing water distribution pipe is clogged with sludge, it is difficult to dredge the pipe, and the use of high-pressure water flushing is ineffective and can easily cause the pipe to burst.

[0004] Based on this, the utility model relates to an anti-blocking anaerobic water distribution device for solving the above-mentioned problems. Utility Model Content

[0009] As a preferred embodiment of the anti-blocking anaerobic water distribution device of the utility model, a movable flange is connected between the HDPE flange head and the fixed flange.

[0010] As a preferred anti-blocking anaerobic water distribution device of the utility model, the bottom end of the HDPE flange head is connected to a national standard DN80 fixed flange, and the bottom end of the national standard DN80 fixed flange is connected to a pre-buried pipe.

[0011] As a preferred anti-blocking anaerobic water distribution device of the utility model, the embedded pipe is sleeved on the outside of the HDPE pipe, and the embedded pipe is fixedly connected to the HDPE pipe through a national standard DN80 fixed flange and a HDPE flange head.

[0012] Compared with the prior art, the beneficial effects of the utility model are:
