Prospectus
1, anaerobism tank body is right cylinder, strengthens resistance to compression tension force.The outermost layer of double layers of tank body, vertical ground, Vertical Design load-bearing steel column, around cylinder, transverse design links crossbeam, not only increases the load-bearing of steel column, strengthens tank body resistance to compression tension force simultaneously.
Tank base 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, on the one hand anti-backflow, 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 skin skeleton construction is built and formed, and strengthen weight capacity, side is designed with People's Bank of China's cat ladder.Internal layer is designed to steel construction, scribbles protective film inside and outside steel construction.Steel construction not only saves cost, and readily conducts heat, and enhances productivity.
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, carry out installation and maintenance machinery; 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, close hermatic door and drainage line valve, open feed pipe valve, liquid high-pressure pump in natural pond is injected in tank body.When the feed liquid in tank body reaches production requirement volume, warning tank starts to report to the police, and staff closes material inlet valve, stops supply 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, the breather hole of biogas by top cover plate designs produced in tank body, enters in the gas storage holder of top design endlessly.
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, close feeding pipeline valve, open discharge conduit valve, by discharge conduit system, natural pond liquid is entered 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, the biogas produced by anaerobic jar injects the reaction solution stirring high speed rotating in tower body with the form of high pressure; Reaction solution simultaneously outside tower also stirs in tower with angled the entering endlessly of high voltage style.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 biogas output.
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.
