Description
Technical field
The present invention relates to a kind of inner loop three phase fluidized bed reactor, specifically a kind of Multi-pipe aerobic internal circulation three-phase biological fluidized bed, belong to biological fluidized bed technical field.
Background technology
Biological fluidized bed refers to the processing efficiency into improving biomembrance process, filler is made and as biofilm carrier using sand (or hard coal, gac etc.), the bottom-up casting bed that flows through of waste water makes carrier layer be flow state, thus strengthen microbial film with the contact area of waste water and abundant oxygen supply in the unit time, and filler boiling state is utilized to strengthen the structures of biological wastewater treatment process.Biological fluidized bed process efficiency is high, take up an area less, reduced investment, beautiful, Deng state is nitrated for sewage, the process of denitrogenation even depth and sewage second-level process and other are containing the Industrial Wastewater Treatment such as phenol, pharmacy.
Inner loop three phase fluidized bed reactor is that of in recent years growing up on the basis of traditional biological fluidized-bed innovates technologies, and application is gradually extensive at present, and existing many cover production equipments are in operation at home.Inner loop three phase fluidized bed reactor by distinguishing up-flow district and Jiang Liu district in bed, utilize the density difference between two regions, circulating of propelling fluid band mobile carrier, finally carrying out being separated of carrier and water outlet in settling region, top, is a kind of biological fluidized bed of improvement.Its advantage is that mixing mass transfer condition is good, not easily carrier demixing phenomenon occurs; Relatively low to the requirement of fluid distributor, be easy to accomplish that fluid well-distributing distributes; In addition, also there is the features such as relatively simple, the shock-resistant ability of structure is strong, sludge output is few.Although biological fluidized bed has above-mentioned plurality of advantages, its popularity is far away from activated sludge process, biological contact oxidation process and biological filter.Major cause is due to fluidization itself, make the design of biological fluidized-bed reactor and the requirement of running management to technology higher.Until today, people are still comparatively superficial to the understanding of fluidisation phenomenon inherent laws, and the design of a large amount of engineering mainly relies on micro-judgment.In investment and working cost, the investment of biological fluidized bed and floor space are only equivalent to 70% and 50% of traditional active sludge aeration tank respectively, but working cost is relatively high, mainly because of the power consumption of fluidisation.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus a kind of Multi-pipe aerobic internal circulation three-phase biological fluidized bed is provided, improve aeration efficiency, reduce working cost, save equipment cost.
According to technical scheme provided by the invention, Multi-pipe aerobic internal circulation three-phase biological fluidized bed comprises pond body, it is characterized in that: the Ti Nei left and right sides, pond is respectively equipped with a point of gas bag, and a point gas bag for the left and right sides is linked into an integrated entity by several aeration flexible pipes; The body left and right sides, pond is respectively equipped with a main tracheae, and the outlet side of each main tracheae connects point gas bag be positioned at bottom the body of pond by a segmental bronchus; Body front and back end, pond is respectively equipped with a support, connecting cross beam inside each support, is linked into an integrated entity between the crossbeam of body front and back end, pond by glasses circle, and aeration flexible pipe, through glasses circle, forms support and connection by glasses circle to aeration flexible pipe; Aeration flexible pipe upper end arranges fluidized-bed gas hood, and fluidized-bed gas hood upper end connects multiple corrugated tube.
Further, segmental bronchus is provided with valve.
Further, fixed angles brandreth in the middle part of the body of pond, corrugated tube is fixed on angle-iron frame by anchor ear.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, improves aeration efficiency, reduces working cost, save equipment cost.

The main tracheae of description of reference numerals: 1-, 2-valve, 3-segmental bronchus, 4-divide gas bag, 5-corrugated tube, 6-fluidized-bed gas hood, 7-pond body, 8-aeration flexible pipe, 9-support, 10-crossbeam, 11-glasses circle, 12-angle-iron frame, 13-anchor ear.
Embodiment
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Fig. 1 ~ 3, the present invention mainly comprises pond body 7, and in pond body 7, the left and right sides is respectively equipped with a point of gas bag 4, and a point gas bag 4 for the left and right sides is linked into an integrated entity by several aeration flexible pipes 8.
Pond body 7 left and right sides is respectively equipped with a main tracheae 1, and the outlet side of each main tracheae 1 connects point gas bag 4 be positioned at bottom pond body 7 by a segmental bronchus 3.
