Abstract
The utility model discloses a separating plate assembly for membrane distillation. The separating plate assembly for the membrane distillation comprises a hot-side separating plate, a compound membrane and a cold-side separating plate which are sequentially superposed alternately, wherein the middle parts of the hot-side separating plate and the cold-side separating plate are hollow to form flow passages; the upper sides of the hot-side separating plate and the cold-side separating plate are provided with parallel hot working medium inlets and cold working medium outlets; parallel cold working medium inlets and hot working medium outlets are arranged on the lower sides of the hot-side separating plate and the cold-side separating plate; the hot working medium inlet and the hot working medium outlet of the hot-side separating plate are communicated with the flow passages; an internal O-shaped sealing ring and an external O-shaped sealing ring are arranged on the front plane and the back plane of the hot-side separating plate respectively; the internal sealing rings encircle the edges of the outer sides of the flow passages; and the hot working medium inlets, the cold working medium outlets, the cold working medium inlets and hot working medium outlets are encircled between the external sealing rings and the internal sealing rings. By adopting the structure that the internal O-shaped sealing rings and the external O-shaped sealing rings are arranged on the front plane and the back plane of the hot-side separating plate and the hot working medium inlets, the cold working medium outlets, the cold working medium inlets and hot working medium outlets are provided with O-shaped sealing rings on the front plane side and the back plane side of the separating plate, the sealing effect is greatly improved.
Description
Technical field
The utility model relates to plate and frame film distillation assembly, relates in particular to the hot working fluid dividing plate and the cold working medium dividing plate of plate and frame film distillation assembly.
Background technology
Film distillation is the new separation technology that a kind of film separation process and evaporation process combine, and is simple to operate with its rejection height, excels at leveraging advantage such as waste heat of plant, used heat and is widely used in industry such as water treatment.Be divided into doughnut formula, plate and frame, rolling and tubular membrane distillation from the different film distillations of modular construction.Hollow-fibre membrane distillation assembly, the intensive encapsulation of fibre bundle, the space is very narrow and small between the film silk, when handling the high viscosity feed liquid, the adhesion of as easy as rolling off a log generation film silk, fenestra stops up, and causes membrane flux to descend rapidly.Because runner is narrower between the hollow-fibre membrane silk, and the film silk cleans quite difficulty once stick together.Plate and frame module is superimposed by hot side dividing plate, composite membrane and cold side dividing plate and forms, has cleaning, check and changes advantage easily, sealing ring places between hot side dividing plate and the composite membrane, hot side dividing plate adopts an O shape circle and the sealing of cold side dividing plate in the prior art, but this kind hermetically-sealed construction sealing effectiveness is good inadequately.
The utility model content
Technical problem to be solved in the utility model just provides the better film distillation of a kind of sealing effectiveness baffle assembly.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of film distillation baffle assembly, comprise the hot side dividing plate that is superimposed successively, composite membrane and cold side dividing plate, wherein hot side dividing plate and cold side dividing plate middle part hollow form runner, hot side dividing plate and cold side dividing plate upside are equipped with hot working fluid import arranged side by side and cold sender property outlet, downside is equipped with cold working medium import arranged side by side, the hot working fluid outlet, the hot working fluid import of hot side dividing plate and hot working fluid outlet are communicated with runner, it is characterized in that: before the described hot side dividing plate, two planes, back all are provided with inside and outside twice O-ring seals, the outer side edges edge, sealing ring circulation road in interior road wherein, the hot working fluid import, cold sender property outlet, cold working medium import and hot working fluid outlet are enclosed between outer course sealing ring and the Nei Dao sealing ring.
As preferably, described hot working fluid import, hot working fluid outlet, cold sender property outlet and cold working medium import all are provided with O-ring seals in hot side dividing plate frontal plane side and back plane side.Enhanced leaktightness.
As preferably, also be provided with the cloth tank that inside is provided with a plurality of poroid runners between described hot working fluid import and hot working fluid outlet and runner.Porous cloth tank has replaced the cloth network of rivers in the middle of the dividing plate, has realized the maximization of film effective area on the one hand, has improved membrane flux; Guarantee that on the other hand current are smooth and easy without hindrance, especially when treatment media is the high concentration high viscosity substance, can prevent effectively that runner from stopping up, reduce diaphragm and pollute, and be easy to the diaphragm on-line cleaning.
As preferably, two side plane outer rings are provided with the outwards outstanding columniform fixing hole of a circle before and after the described hot side dividing plate, described cold side dividing plate is also corresponding to be provided with circular fixing hole, and the projecting height of the columniform fixing hole of described hot side dividing plate equals the thickness of described cold side dividing plate.Easy for installation.
The utility model all is provided with inside and outside twice O-ring seals on forward and backward two planes of hot side dividing plate, hot working fluid import simultaneously, hot working fluid outlet, cold sender property outlet and cold working medium import all are provided with O-ring seals in dividing plate frontal plane side and back plane side, the one, prevent that diaphragm is shifted in installation process, make easier the carrying out of installation of membrane module; The 2nd, prevent that diaphragm from breaking in installation and running; The 3rd, guarantee when membrane module moves the seepage phenomenon not to take place yet under condition of high voltage, sealing effectiveness has improved a lot.
