prospectus
1, anaerobism tank body is right cylinder, strengthens anti-pressure ability.Bottom design feeding discharging material pipeline, this pipeline is designed with opening-closing valve.Be positioned at the discharge port of tank, design and installation loader, anti-backflow on the one hand, on the other hand uniform distribution.The discharging arm that loader is bending, impels the overall evenly rising of fresh feed liquid.Top feed liquid flows to secondary anaerobic jar from overflow spout.Secondary anaerobic jar discharge port design anti-return lid, during charging, anti-return lid is opened automatically; When stopping feed, anti-return lid is closed automatically.
Tank body divides inside and outside two-layer, and outer metope cast iron casting swinging cross structure building forms, and side is designed with People's Bank of China's cat ladder.Internal layer wall surface design is cast iron casting swinging cross structure.Protective film is scribbled inside and outside this structure.
Upper end design gas storage holder, and design annular walkway.Tank top and gas storage holder contact position, design a cover plate, the circular breather hole of upper design of cover plate; Cover plate is in order to support gas storage film because subsiding without during gas, and the biogas produced in tank is delivered in tank deck gas storage holder by breather hole.Gas storage holder is designed with gas pipe line, transparent glass vision slit.Biogas in gas storage holder is sent outside by gas pipe line, and cabinet inner case observed by vision slit.
In the central authorities of tank deck circular cover, by crossbeam as bearing beam, downward suspension design one sealing chamber, this room seals, and to prevent in tank body biogas to outward leakage.Then the airtight walkway of transverse design one, is in communication with the outside sealing chamber interior.
Traverse sealing room and vertical with walkway, design enclosed ventilation road, sealing chamber inside is connected with the external world.
Walkway is airtight, prevents biogas in tank from revealing, facilitates people to enter this secret room simultaneously, enter row peacedress servicing machine; Ventilation duct ventilates for sealing chamber on the one hand, and another aspect is sealing chamber daylighting, its closed state, for preventing in tank body biogas to outward leakage.
At this close indoor location power set and the whipping appts that lets droop in the liquid of natural pond.This passageway walls designs glass transparent vision slit, can open; On sealing locular wall, design can shutter door, outdoors design and installation auto-alarm.
When people enters sealing chamber operation, abhiseca loop corridor must be entered by the cat ladder outside tank body, then enter sealing room by the folding step being located at annular walkway opening.
2, closehermatic door and drainage line valve, open feed pipe valve, liquid high-pressure pump in natural pond injected in tank body.When the feed liquid in tank body reaches production requirement volume, warning tank starts to report to the police, staff closematerial inlet valve, stopsupply feed liquid.
3, as observed the situation in tank, available torch irradiates the transparent glass the opened vision slit that sealing chamber and walkway are designed, and observes the situation in tank body by vision slit.As vision slit is opaque, can open and wipe dirt settling, observe again after closedown.
4, stirring one is at least started shooting every day to secondary, at every turn about 1 hours.Also can repeatedly stir, also sustainable stirring.
5, produce in tank body biogasby the breather hole that top cover plate designs, endlessly entertop design in gas storage holder.
6, anaerobism tank body top and gas storage film contact position, ring surrounding is designed with People's Bank of China corridor, so that ongoing operations.
7, gas storage holder mesentery tool material makes, and opens airflow hole above, design transparent glass vision slit.Airflow hole is connected with pipeline, flows to user.
8, outside anaerobism tank skin, design thermal insulation layer; Tank body bottom position, design condensate drain; This discharge conduit designs opening-closing valve, and valve is opened in timing, discharges water of condensation.
9, the discharge conduit of tank body lower part and hermatic door, is normally in closing condition when producing.When tank interior needs repairing, closefeeding pipeline valve, opendischarge conduit valve, by discharge conduit system, enters natural pond liquid in waste firedamp liquid pond.After draining, open hermatic door, remaining biogas in the tank body that disperses, people is allowed for access operation in tank.
10, anaerobic jar is produced biogasinject with the form of high pressure stir towerin body high speed rotating reaction solution in; Simultaneously outside tower reaction solutionalso with high voltage style angledenter endlessly and stir in tower.Biogas and reaction solution after mix and blend, enter reaction tower by top duct in stirring tower.
Reaction tower can design multiple, forming reactions tower group, and is interconnected.Knockout tower is entered again by reaction tower.Because biogas is water insoluble, in knockout tower, reaction solution is separated with biogas.Liquid enters settling tank, and gas enters gas-holder.
In knockout tower, the speed that reaction solution enters is identical with the speed of discharge, does not take separated biogas storage space to reaction solution; knockout tower can design multiple series connection application, until biogas classification totally.
When purification tower needs repairing, close associated valve, discharge liquid in tower from tower bottom liquid outlet, carry out detachable maintaining.
After reaction solution precipitation in settling tank, add reactant Posterior circle recycling.
11, the combustion gas after purification is supplied to generating set generating, and is supplied to user's use.
12, by the high-temperature-hot-water that generating set produces, in hot well tank, send into gas fired-boiler by pressure pump vaporize, heat to the natural pond liquid in anaerobic jar, improve biogasoutput.
13, with the sanitary sewage such as cities and towns, plant, and in farmland, growing plants stalk is raw material, makes natural pond liquid in the liquid pool of natural pond, then stirs, while squeeze into main anaerobic jar by high-pressure pump.
beneficial effect of the present invention
This anaerobic jar group, on the basis of original production, eliminates the weir tank holding overflow substance.Single tank body is produced, changes into array mode, form a Production Flow Chart.Improve natural pond liquid production efficiency and gas production rate.
Anaerobic jar group and purification tower group, generating set, pressure pump and gas fired-boiler are combined, can be complementary.Play economize in raw materials, raise the efficiency, the effect of protection of the environment.
