Utility model content

The purpose of this utility model aiming at currently, China as large agricultural country, with the hair of domestic animals and fowls aquaculture Exhibition is risen extracting biogas technology since excrement, and biogas can contain from the biogas slurry extracted in fermentor in reaction extraction process There is part biogas, direct emission causes to waste, simultaneously because needing to carry out net containing environment is polluted after sulfide emission in biogas To change, purifies each system smooth working before cleaning for holding, need to use surge tank, existing biogas slurry buffer tank structure is simple, Gas and liquid separating rate in biogas slurry is slow, and the impurity in biogas slurry need natural sedimentation after separated, influence production effect The deficiency of rate, and a kind of biogas slurry surge tank is provided.

The utility model includes buffering tank body and agitating device, and buffering top of the tank is provided with gas outlet, buffers tank base Inlet and sewage draining exit are had, and is equipped with inlet tube on the inlet of buffering tank body, liquid outlet one end of inlet tube is inserted Enter into surge tank body, the equal drift net plate of hemispherical is equipped in surge tank body, the equal drift net plate of hemispherical is located at the liquid outlet of inlet tube Top, agitating device include stirring motor, agitating shaft and stirring blade, and stirring motor is mounted on buffering top of the tank, and passes through Agitating shaft drives stirring blade to rotate in surge tank body, and stirring blade is located above the equal drift net plate of hemispherical；Buffer tank body Side is equipped with temporary storage tank, is provided with inlet at the top of temporary storage tank, the bottom of temporary storage tank is provided with leakage fluid dram, buffers on the side wall of tank body It is provided with overflow port, the overflow port for buffering tank body is communicated by the inlet of U-tube and temporary storage tank, and the inlet of U-tube is located at slow The lower section of the equal drift net plate of hemispherical in tank body is rushed, and is equipped with filter packing layer in the liquid feeding end of U-tube.

Liquidometer is equipped in surge tank body.

Overflow open height of the feed liquor open height of temporary storage tank lower than buffering tank body.

The utility model advantage is: being flowed by the equal drift net plate of hemispherical to the biogas slurry of entrance, while passing through stirring Device is stirred the speed for improving gas-liquid separation, and the biogas slurry after separation enters temporary storage tank storage after filtering by filter packing layer It deposits, facilitates the impurity in separation biogas slurry.

Detailed description of the invention

Fig. 1 is the utility model structure diagram.

Specific embodiment

As shown in the picture, the utility model includes buffering tank body 61 and agitating device, buffers and is provided with outlet at the top of tank body 61 Mouthful, buffering 61 bottom of tank body has inlet and sewage draining exit, and inlet tube 63 is equipped on the inlet of buffering tank body 61, Liquid outlet one end of inlet tube 63 is inserted into buffering tank body 61, is equipped with the equal drift net plate 64 of hemispherical, hemisphere in buffering tank body 61 The equal drift net plate 64 of shape is located above the liquid outlet of inlet tube 63, and agitating device includes stirring motor 65, agitating shaft 66 and paddle Piece 67, stirring motor 65 is mounted on 61 top of buffering tank body, and drives stirring blade 67 in buffering tank body 61 by agitating shaft 66 Interior rotation, stirring blade 67 are located at equal 64 top of drift net plate of hemispherical；The side for buffering tank body 61 is equipped with temporary storage tank 68, temporary storage tank 68 top is provided with inlet, and the bottom of temporary storage tank 68 is provided with leakage fluid dram, buffers and is provided with overflow port on the side wall of tank body 61, buffers The overflow port of tank body 61 is communicated by the inlet of U-tube 69 and temporary storage tank 68, and the inlet of U-tube 69 is located at buffering tank body 61 The lower section of the interior equal drift net plate 64 of hemispherical, and filter packing layer 70 is equipped in the liquid feeding end of U-tube 69.

It buffers and is equipped with liquidometer 71 in tank body 61.

Overflow open height of the feed liquor open height of temporary storage tank 68 lower than buffering tank body 61.

Working method principle: the biogas slurry being discharged out of fermentor from inlet tube 63 enter buffering tank body 61 in after by hemisphere The equal stream of drift net plate 64 of shape is broken up, and is then stirred by stirring blade 67, accelerates the separation of gas and liquid in biogas slurry, stirred The liquid flow velocity for being located at equal 64 top of drift net plate of hemispherical in journey is faster than lower section, and the contamination precipitation in biogas slurry is facilitated to buffer 61 bottom of tank body, gas is drained into next station from the exhaust outlet at 61 top of buffering tank body and is purified, when in buffering tank body 61 When the liquid level of biogas slurry is higher than overflow port, the biogas slurry positioned at buffering 61 bottom of tank body after the filtering of filter packing layer 70 by being drained into temporarily It deposits in tank 68, after the liquid level that liquidometer 71 is shown is higher than setting height at the top of overflow port, represents biogas slurry in temporary storage tank 68 and fill, Stop at this time to buffering tank body 61 in convey biogas slurry, be provided with buffering tank body 61 sewage draining exit to buffering tank body 61 in biogas slurry and The sediment for being deposited in buffering 61 bottom of tank body is discharged, the biogas slurry reflux in discharge process in U-tube 69, filter packing Impurity on layer 70 rinses out.
