Description of drawings
Fig. 1 is the structural representation that the house refuse device is handled in this diphasic anaerobic circulation washing.
Specific embodiments
The utility model is done by specific embodiments below in conjunction with accompanying drawing and to be described in further detail.
As shown in Figure 1,1 is washing pool, can be based upon underground, saved the soil, 2 is the charging aperture of washing pool, and 3 is gas outlet II, 4 for being arranged on the screen cloth in the washing pool, and 5 for having the biogas rinse mouth of control biogas flush switch, and it is arranged on the top of screen cloth 4,6 is the effluent recycling mouth, and 7 is the biogas holding vessel, and 8 is inlet, 9 is anaerobic fermentation tank, can be high efficiency anaerobic reactor, and 10 is gas outlet I, 11 is liquid outlet, and it leads to effluent recycling mouth 6.
This device mainly comprises washing pool 1, anaerobic fermentation tank 9, and biogas circle irrigation system and effluent recycling recycle system.Present technique is with separate relative with liquid of solid matter of organic domestic waste, solid matter is trapped in the washing pool further that hydrolysis acidification changes into deliquescent solution, and the dissolubility solution that is changed into by washing enters methanator (being anaerobic fermentation tank) as water inlet.Because liquid outlet 11 leads to effluent recycling mouth 6, so that water outlet all is back in the washing pool 1 is recycling as water lotion, effluent recycling can play stirring action to the feed liquid in the washing pool simultaneously
Gas from gas outlet II3 and gas outlet I10 is collected in preservation in the biogas holding vessel 7.Biogas rinse mouth 5 has the switch block of control biogas flushing, what the biogas in the biogas holding vessel 7 was regular washes screen cloth 4 in the washing pool 1, guarantee that screen cloth is not blocked, and increase the stirring action in the washing pool, make that the house refuse in the washing pool can effectively be separated by continuous carrying out.
In the foregoing description, in washing pool 1, be provided with screen cloth 4, its objective is to make the large granular impurity that flows in the anaerobic fermentation tank 9 still less.In actual production, can not establish screen cloth 4, and make supernatant liquid from washing pool 1, discharge as water outlet with precipitation, be connected with anaerobic fermentation tank 9 by inlet 8 so set out mouth on the top of washing pool 1.
This device is gone up the gas outlet II3 and the biogas rinse mouth 5 that are provided with and can be stirred washing pool 1, thereby helps the mixed precipitation of liquid, raises the efficiency.
After domestic waste is collected, carry out certain sorting after, put in the washing pool 1 by charging aperture 2, through the washing effect of certain hour, the organic substance in the organic domestic waste will constantly dissolved entry in.Liquid in the washing pool enters in the anaerobic fermentation tank 9 by inlet 8 and reacts by being arranged on screen cloth 4 in the washing pool 1 back that is separated.The gas that produces in washing pool 1 and the anaerobic fermentation tank 9 is collected in the biogas holding vessel 7 by gas outlet II3 and gas outlet I10.The regular extraction of biogas in the biogas holding vessel 7 is washed by the screen cloth 4 in 5 pairs of washing pools 1 of biogas rinse mouth, the obstruction of avoiding the particulate matter in the house refuse that plug is netted.Be collected in the biogas holding vessel by the gas outlet II3 in the washing pool 1 once more through flushing back biogas.Water outlet in the anaerobic fermentation tank 9 enters in the washing pool 1 by effluent recycling mouth 6 through liquid outlet 11, for washing pool has replenished water lotion, and washing pool 1 is had certain stirring action, thereby the obstruction of having quickened the hydrolysis of house refuse and having avoided filling in net 4 to a certain extent.Whole system does not have the water outlet discharging, has avoided secondary pollution, and biogas can be utilized by secondary.House refuse can be dissolved and Separation of Solid and Liquid in washing pool 1 fully, and the matrix that is easy to methanation is provided for anaerobic fermentation tank.
Washing pool 1 preferred rectangle.In washing pool 1 inside or outside heater can be set, so that it is heated, thereby make house refuse to dissolve faster.
This two-phase circulation washing is handled the house refuse device and can be had the marsh gas power generation device, this marsh gas power generation device utilizes the marsh gas power generation of biogas holding vessel 7, this marsh gas power generation device has the generating waste-heat retracting device, this generating waste-heat retracting device communicates with washing pool 1, makes the waste heat of generating be used for washing pool is heated.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
