Biogas digester water current impact anti-sedimentation device convenient for additional mounting

Abstract

The invention provides a biogas digester water current impact anti-sedimentation device convenient for additional mounting. The biogas digester water current impact anti-sedimentation device convenient for additional mounting has the function of preventing biogas residue from sedimentation and is suitable for additional mounting of biogas digesters which are built and put into use. According to the adopted technical scheme, a high-pressure water pump is arranged outside a biogas digester, a water suction pipe connected to one end of the high-pressure water pump is accessed into biogas slurry on the upper part of a biogas slurry tank, the other end of the high-pressure water pump is accessed into the biogas slurry at the bottom of the biogas digester through a water outlet pipe of a sealedflange plate arranged at the top of the biogas digester, and the water outlet pipe is connected with three uniformly distributed spray heads. The biogas slurry is drawn from the biogas slurry tank bythe high-pressure water pump, and high speed water current is regularly sprayed at the bottom of the biogas digester through the water outlet pipe and the spray heads additionally mounted at the top of the biogas digester, so that the biogas residue cannot settle; the sealed flange plate arranged at the top of the biogas digester is used for fixing the water outlet pipe and the spray heads so thatthe water outlet pipe and the spray heads are easy to additionally mount, maintain, and replace; and the biogas digester water current impact anti-sedimentation device convenient for additional mounting has the advantages of being simple in structure, convenient to additionally mount, and easy to maintain and replace.

Description

technical field [0001] The invention relates to an anti-sedimentation device, in particular to a water flow impact anti-sedimentation device which is conveniently installed in a methane pool. Background technique [0002] At present, the biogas digesters built in rural areas have the problem that the biogas residues are easy to settle. In the long run, the volume of the biogas digesters will be reduced, which will affect the gas production effect. The existing technology is "the biogas digester water impact anti-sedimentation device (201520707365.8)" , because the spray head is set at the bottom of the biogas digester, it should be installed from the outside of the biogas digester inward, which is inconvenient for the maintenance and replacement of the spray head and pipes, and for the current large underground and semi-underground biogas digesters, only It can be installed when the pond is being built, but it is not suitable for the installation of biogas digesters that hav...
