Description
Technical field
Utility model is the improvement that is divided into the biological fluidized bed reactor of multi-region internal recycle arranged side by side about pair cross-section, relates in particular to fluidized-bed sectional improvement arranged side by side.
Background technology
Aerobic biological fluid-bed with its efficient advantage, in water treatment, obtain paying attention to.Prior art is inside circulation triphase fluidized bed, adopts tower concentric inside and outside barrel structure, and inner core is set to aeration up-flow district, and annular space is set to fall stream district between inner/outer tube, forms treating water ciculation fluidized in process cartridge.Yet for keeping Internal Circulating Fluidized Bed that good hydraulic characteristic and carrier fluid effect are arranged, and high coefficient of oxygen utilization, aspect ratio (H/D) general requirement is greater than 4, like this along with the fluidized-bed large scale development, the increase of fluidized-bed diameter, must cause highly bigger increase, the Internal Circulating Fluidized Bed of the single inner tube structure of this kind, when diameter during greater than 4 meters, it highly reaches about 16-20 rice, fluidized-bed reactor like this, and not only intensity is restricted, and too high height, also may exert an influence to surrounding environment.For overcoming the deficiency in the aforementioned Internal Circulating Fluidized Bed amplification, Chinese patent 03136616.3 proposes to adopt honeycomb section structure fluidized-bed, be that the center is provided with little inner core in the fluidized-bed reactor urceolus, the even number that annular space is provided with some even separations between inner/outer tube is dividing plate radially, the inner/outer tube annular space is separated into even number covering of the fan district, alternate covering of the fan bottom is provided with aerating apparatus, makes adjacent covering of the fan form aeration up-flow district respectively and flows district's internal recycle with falling.This honeycomb type section structure fluidized-bed, because the district retrains respectively to reactor ascending, descending stream, single fluidization regions cross section reduces, greatly reduce the fluidized-bed reactor whole height,, can make the fluidized-bed reactor height keep 9-10 rice by the subregion of different cross-sectional is set, construction cost and difficulty of construction have been reduced, reduce working cost, and can keep the higher aspect ratio of fluidisation, overcome the deficiency of existing single inner core inner loop fluidized bed reactor structure.
Yet, reactor is separated into several covering of the fan structures by dividing plate radially, still find some deficiency through practical engineering application, for example carry on as before the height of higher relatively (9-10m) is arranged, separating the steel plate dividing plate needs manually to weld in tube, and also need apply corrosion protection coating, and manufacture difficulty is very big, especially highly vertical for guaranteeing that each dividing plate of high-quality fluidisation needs, increased manufacture difficulty especially.If keep good fluid effect, it is too small to cut apart the cross section, makes difficulty especially; If it is excessive to cut apart the cross section, then be difficult to satisfy the minimum limit value of aspect ratio (H/D) again, can influence fluidisation and treatment effect.Secondly,, all need independent design calculation, increased workload, also be unfavorable for standardized production simultaneously to design for different diameter fluidisation tube for satisfying desirable fluidisation aspect ratio.Besides, the covering of the fan of separating is the non-centrosymmetry cross section, up-flow district aeration is difficult to accomplish that total cross section is even, the cross section aeration is inhomogeneous, produces the fluid wall attachment effect for a moment, and promptly liquid and carrier mixed solution are bigger along the dividing plate flow velocity, dividing plate centre flow velocity is less relatively, can appear at the inner inner fluidisation of formation of lattice or cause carrier to be in suspended state, form the slough, influence the reactor for treatment effect in lattice inside; Two can cause carrier filler to be piled up to a position, finally can make interior all carrier fillers of reactor all be deposited in a certain bottom position of fluidized-bed, cause and have only sewage in the reactor in fluidisation, influence treatment effect greatly, aeration ununiformity probability between separating simultaneously and separating can increase, and therefore stability is not ideal enough.In addition, this structure fluidized-bed is unique can only to adopt all steel system structure, particularly anticorrosion big with maintenance workload, and therefore still having is worth improved place.
The utility model content
The utility model purpose is to overcome the deficiency of above-mentioned prior art, and a kind of advantage that both can keep similar honeycomb section structure is provided, and can overcome above-mentioned all insufficient tubular organism fluidization reactors again.
The utility model purpose realizes, the main improvement is that the fluidized-bed cylinder internal diameter is separated to dividing plate, changes that some tubulations are alternate to be set up in parallel into, and in each tubulation bottom aerating apparatus is set, thereby overcome the deficiency of dividing plate cellular-type honeycomb type section fluidisation bio-reactor, realize the utility model purpose.Specifically, the utility model tubular organism fluidization reactor comprises the section a plurality of arranged side by side that outer cylinder body and Qi Nei plurality of parallel are separated to form, and it is characterized in that the said alternate side by side perpendicular vertical tubulation put that is divided into side by side, and each tubulation bottom is provided with aerating apparatus.Like this, each tubulation is distinguished as the shared stream that falls between each tubulation in the urceolus as the up-flow district, and the subregion that is formed in the urceolus is inner circulation fluidized.
The described vertical tubulation of utility model can adopt desirable fluidizing cylindrical duct, so more meets the fluidisation requirement, also can adopt centrosymmetry Polygons pipe, wherein the limit number is many more, the required rounded section of approaching more desirable fluidisation, and it is even that above-mentioned centrosymmetry cross section structure more helps aeration.Tubulation can adopt metal tube, but more preferably adopts the non-metallic pipe do not need to establish in addition preservative coat, for example plastics tubulation, glass reinforced plastic tubulation etc., and can adopt pultrude process production efficiently.Tubulation diameter (Polygons is a circumscribed circle diameter) is more suitable with 0.6-1.2 rice, and the tubulation height is more suitable with 5-10 rice.Tubulation is installed, 20-60cm is comparatively suitable with the distance bottom, and is excessive apart from distance from bottom, can cause sewage and bio-carrier mixed solution to reduce with the flow velocity of the connected region of falling the stream district in fluidized-bed up-flow district, and then cause carrier filler and mud to pile up in the bottom, influence fluid effect; Too small apart from distance from bottom, then can cause sewage and bio-carrier mixed solution in fluidized-bed up-flow district with fall that flow reduces in stream district's connected region, cause up-flow district (tubulation), to fall stream district fluidisation inhomogeneous.The alternate setting of each tubulation, uniform distribution in the urceolus cross section, the tubulation number is with its each tubulation area and account for total area 40-60% and determine, can not influence fluid effect yet, certainly ratio be 1: 1 or near 1: 1 better, for satisfying, also can adopt the combination of different tube diameters tubulation to keep the up-flow district as far as possible and to fall the Liu Qu cross section approaching substantially, as long as design keeps cross section aeration flow velocity basically identical, can't influence fluid effect.
Utility model shell and tube fluidisation bio-reactor, owing to adopt the alternate structure that is provided with of vertical tubulation, replace dividing plate to separate covering of the fan with tubulation, not only kept the radially advantage of dividing plate separation covering of the fan formation honeycomb section structure fluidized-bed of prior art, and overcome the deficiency of its existence.Adopt alternate tubulation honeycomb section structure, make simply, can be prefabricated into tubulation and install, do not need manually to pierce welding, particularly can adopt the plastics extrusion forming, greatly facilitate production, installation and repair and maintenance, do not need to add in addition rotproofing, better solved anticorrosion and maintenance issues; Secondly, can design limited serial tubulation, form the standard fashion-parts, help standardized production, the cord wood assembling has reduced design, production management complexity, and field assembly is convenient, save a large amount of scene splicings, required welding is installed, reduced manufacturing cost, making precision more can be near design requirements, and amplifies treatment capacity, only need to increase the urceolus diameter, can guarantee desirable fluidisation aspect ratio not increasing under the height situation.Besides, the premolding tubulation can be pre-assembled (being coupled as one) with aerator with up-flow, appropriate diameter (0.6-1.2m), and centrosymmetry is circular or near circular configuration, and the aeration good uniformity more can guarantee the homogeneity of aeration, guarantees good fluid effect.Tubular structure, the shared stream district of falling, up-flow district be with to fall stream district corner big, helps more that whole fluidized-bed is inner to form good fluid effect.Above-mentioned various advantages is for prior art dividing plate cellular-type can not be realized.
