Abstract
The utility model discloses a kind of internal circulating membrane reactor, include urceolus and membrane module, an inner sleeve is provided with in urceolus, the cylindrical structure of described membrane module, membrane module is arranged in inner sleeve, and the lower end barrel of described urceolus is provided with water-in, the two ends, bottom surface of urceolus are respectively equipped with aeration opening, the aeration opening at two ends is positioned at the outside of inner sleeve, is communicated with rising pipe in the membrane module of described cylindrical structural, and described rising pipe stretches out through urceolus.The utility model texture improvement is simple, has additional inner sleeve and carry out aeration outside inner sleeve, substantially improving mixed solution oxygen supply condition, making mixed solution form circulation in reactor, improve gas-liquid mass transfer effect, suppresses film blocking.
Description
Technical field:
The utility model relates generally to separating and filtering technical field, mainly a kind of internal circulating membrane reactor.
Background technology:
Membrane reactor is widely used in water treatment, and current conventional membrane reactor is in operation and easily causes the flow velocity of placing membrane module side to diminish, thus causes gas-liquid mass transfer deleterious, membrane module to block, and short flow phenomenon even occurs.Thus need the homogeneity that can improve gas-liquid mass transfer effect, fluidised form in conventional membrane reactor and improve flow velocity, suppress the device of the generation of film latch up phenomenon.
Utility model content:
Technical problem to be solved in the utility model is to provide a kind of internal circulating membrane reactor, its texture improvement is simple, have additional inner sleeve and carry out aeration outside inner sleeve, substantially improve mixed solution oxygen supply condition, mixed solution is made to form circulation in reactor, improve gas-liquid mass transfer effect, suppress film blocking.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of internal circulating membrane reactor, include urceolus and membrane module, it is characterized in that: in described urceolus, be provided with an inner sleeve, certain distance is provided with between inner sleeve and the inner bottom surface of urceolus, the cylindrical structure of described membrane module, the membrane module of cylindrical structural is arranged in inner sleeve, the lower end barrel of described urceolus is provided with water-in, the two ends, bottom surface of described urceolus are respectively equipped with aeration opening, the aeration opening at two ends is positioned at the outside of inner sleeve, be communicated with rising pipe in the membrane module of described cylindrical structural, described rising pipe stretches out through urceolus.
The membrane module of described cylindrical structural is made up of PVC board, wire netting and bolting silk (100 μm, aperture).
The utility model has the advantages that:
The utility model texture improvement is simple, has additional inner sleeve and carry out aeration outside inner sleeve, substantially improving mixed solution oxygen supply condition, making mixed solution form circulation in reactor, improve gas-liquid mass transfer effect, suppresses film blocking.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Embodiment:
See Fig. 1, a kind of internal circulating membrane reactor, include urceolus 1 and membrane module 2, an inner sleeve 3 is provided with in described urceolus 1, certain distance is provided with between the inner bottom surface of inner sleeve 3 and urceolus 1, the described cylindrical structure of membrane module 2, the membrane module 2 of cylindrical structural is arranged in inner sleeve 3, the lower end barrel of described urceolus 1 is provided with water-in 4, the two ends, bottom surface of described urceolus 1 are respectively equipped with aeration opening 5, the aeration opening 5 at two ends is positioned at the outside of inner sleeve 3, rising pipe 6 is communicated with in the membrane module 2 of described cylindrical structural, described rising pipe 6 stretches out through urceolus 1.
The membrane module 2 of described cylindrical structural is made up of PVC board, wire netting and bolting silk (100 μm, aperture).
The high 1000cm of urceolus 1, diameter 50cm in the utility model; Inner sleeve height 50cm, diameter 30cm; Inner sleeve 3 is apart from urceolus inner bottom part 15cm; In inner sleeve cylindrical structural membrane module 2 on diameter of going to the bottom be 20cm, high 40cm.The arranged outside aeration opening 5 of inner sleeve 3 bottom urceolus 1, when operating operation, carrying out aeration, substantially improving mixed solution oxygen supply condition, making mixed solution form circulation in reactor, improve gas-liquid mass transfer effect outside inner sleeve.
In experimentation, gas is provided by air pump, is distributed in urceolus via gas distributor by aeration opening, utilizes the freeboard difference automatic outletting of liquid level and rising pipe.
Testing simulation trade effluent used adopts water inlet for the domestic sewage from campus of Anqing Teachers College, wherein initial pH=6.8, COD=408mg/L, TN (total nitrogen)=110mg/L, TP (total phosphorus)=7mg/L.
Conventional membrane reactor and internal circulating membrane reactor for treatment effectiveness comparison
