Abstract
A self-regulating efficient gas-liquid cyclone separator for treating sewage is composed of a casing consisting of cylindrical upper half and conic lower half, a water inlet pipe consisting of primary lifting pipe and starting secondary lifting pipe, a water outlet pipe, and a marsh gas guiding pipe.
Description
Technical field
The present invention relates to the circulation anaerobic sewage treatment equipment, especially relate to the whole gas-liquid separator of a kind of high-efficiency self.
Background technology
Present employing gas is carried the high efficiency anaerobic reactor of energy reinforcement mass-transfer efficiency in conversion process of energy, all will use gas-liquid separator.There is following problem in conventional gas-liquid separator: (1) starts with normally in service at anaerobic reactor, and gas production differs 10～20 times, even bigger; And satisfying the gas-liquid separator of a certain gas production and stripping tube under other state, operating efficiency is low, even can not move; When (2) taking impulsive force and big shearing force to realize gas-liquid separation, cause granule sludge fragmentation in the mixed liquor easily, and reduced the high organic loading of circulation anaerobic sewage treatment equipment; (3) if only take the method for Gravity Separation, then bubble is all undesirable from overflowing of interface to the diffusion and the gas at gas-liquid separation interface, increases the void fraction that refluxes, and reduces cyclic transformation efficient.
Summary of the invention
The object of the present invention is to provide a kind of adapt to start and operation gas production great variety, high efficient gas and liquid can be separated and keeps that the granule sludge integrality organically combines, separation efficiency height, high-efficiency self simple in structure, that cost is low put in order cyclone gas-liquid separator.
The object of the present invention is achieved like this: the present invention is made up of shell separator, water inlet pipe, outlet pipe and biogas conduit, shell separator is made up of upper shell and lower house, the biogas conduit is installed in the central top of upper shell, outlet pipe is installed in the lower house bottom, feature is that being shaped as of upper shell is cylindric, and being shaped as of lower house is coniform.
Water inlet pipe is made up of main riser and startup subsidiary riser, main riser with vertical with central shaft, tangentially enter upper enclosure inner wall cylindraceous and be affixed on upper casing side inwall, start subsidiary riser with vertical with central shaft, tangentially enter cone shape lower house inwall at 1/3～1/4 place, lower house top and be affixed on lower casing side inwall.
Starting the subsidiary riser diameter is 1/2 of main riser diameter.
Main riser is consistent with the delivery port direction that starts subsidiary riser, and main riser is connected in isometry position with startup subsidiary riser lower end.
The coning angle that is shaped as of lower house is 60 °～90 ° coniform.
Shell separator of the present invention by upper shell cylindraceous and coniform be that funnel shaped lower house is formed, and water inlet pipe is by forming from the main riser of upper shell feed liquor with from the startup subsidiary riser of lower house feed liquor, promptly adopt unique mixed liquor water intake mode is set, thereby the kinetic energy of liquid flow in the time of can making full use of mixed liquor and enter gas-liquid separator produces spiral-flow type mixed liquor stream.The characteristics of this water intake mode are:
(1), avoids granule sludge in the mixed liquor be impacted power and very big shearing force and fragmentation;
(2), the utilization centrifugal force field makes gas-liquid separation very effective.
Gas production is little, the mixed liquor of lifting more after a little while, the three-dimensional spiral type of flow of structure of the present invention and mixed liquor is obvious for the benefit of separating; At this, only need illustrate that gas production is big, promote big, the situation when speed is high of liquid measure of mixing.The benefit that the present invention brings: A. gas-liquid separation interface forms waveform, ring-type parabola, has increased considerably gas and has overflowed the interface; B. mixed liquor flows and exists three kinds of forms at least: external spiral stream, circular flow (the closed loop eddy current of liquid internal) and inside spin stream, and in be formed centrally air cylindrical surface, because maelstrom does not have fragmentation to bubble, and the bubble in the mixed liquor is under the thrust that the mixed liquor of buoyancy, inertia force difference and three kinds of forms flows: 1.. minute bubbles are easy to aggregate into air pocket, and air pocket overflows easier the breaking of gas-liquid interface; 2.. the rapider flow direction and be distributed in the central gas cylinder and ring-type parabolic gas-liquid interface.D. change the condition of finally breaking of bubble, quicken gas and overflow at gas-liquid interface.At liquid level, the static bubble condition of breaking is a bubble liquid level top gravity and capillary unbalance; Unbalance between making a concerted effort of bubble liquid level top gravity and centrifugal force and the surface tension changed in the spin that bubble produces in the spiral ascending motion, the condition that bubble is broken.Because inside spin speed is bigger, near the central gas cylinder, this acceleration gas overflows and seems more obvious.
The present invention is owing to be provided with unique main riser and start subsidiary riser, starting the subsidiary riser diameter is 1/2 of main riser diameter, main riser and startup subsidiary riser are installed on the position of gas skirt, make them produce appropriate couples back when liquid flow, its self-adjusting kinetic energy is achieved in that
Circulation anaerobic reactor start-up operation, its gas production are enough to pressure reduction that the inside and outside density contrast of stripping tube is produced, reach the threshold values that starts subsidiary riser.Mixed liquor enters in the shell separator through starting subsidiary riser, flows out from outlet pipe then, and formation circulates.Because mixed liquor flows to the dynamic differential pressure of all sides; Make the former part bubble that may enter main riser, trail and enter the startup subsidiary riser, form that to start in the subsidiary riser density littler, and produce positive feedback effect; Reduce to cause speed to increase until density, the reaction that tube wall resistance and viscosity resistance occur increases with the increase of mixed liquor speed reaches dynamic balance.In running, when gas production reached normal operating condition 50%～70% gas production, because it is thinner to start subsidiary riser, resistance was bigger; At this moment backflow mixed liquor has also covered its outlet, and the necessary bigger promotion resistance of eddy flow is also appearred producing in its outlet; Startup subsidiary riser porch mixed liquor is not a linear relationship to the dynamic differential pressure and the gas production of all sides, and the bubble ratio that enters main riser increases, and main riser occurs and reaches threshold values, and mixed liquor enters and circulates in the main riser.Positive feedback effect appears in major cycle, and the major cycle positive feedback effect is negative-feedback for starting subsidiary riser, and the quantity that finally makes main riser, startup subsidiary riser promote mixed liquor is managed shunting by the form realization mixed liquor of energy loss minimum two and circulated.The present invention need not to be provided with valve again, can guarantee the starting state and the running status of circulation anaerobic reactor, and gas is put forward function and normally brought into play; And in this two states, main riser and the mobile of gas and liquid mixture that starts in the subsidiary riser are that the rill shape flows; And the adaptive streaming process that the energy loss minimum is arranged is so operational efficiency is the highest.
In sum, the present invention has keeping the granule sludge integrality and strengthening high efficient gas and liquid and separates and organically combine, and can be adapted to start and normal operating efficient gas is put forward the conversion, movement-less part of energy, simple in structure, advantage that cost is low, is a kind of gas-liquid separator of novel interior (gas stripping type, self-driven) anaerobic reactor that circulates.
