Description
Technical field
The present invention relates to a kind of microporous aeration device, particularly one floats microporous aeration device automatically.
Background technology
The biological treatment of sewage is the organism utilizing microorganism to come in absorption, decomposition, oxidation sewage, is stablize harmless material, thus sewage is purified the organic matter degradation of instability.Modern biological treatment, by the difference of effect microorganism, can divide aerobic oxidation and the large class of anaerobic reduction two.The former is widely used in Treating Municipal Sewage and Organic trade effluent.
Microporous aeration device is adopted to input source of oxygen in sewage disposal device in sewage, existing microporous aeration device, be all lay with hard pipeline (mainly UPVC or ABS pipeline) bottom being fixed on aeration tank, then micro porous aeration head be contained in above the pipeline laid.Source of the gas is nearly all provided by roots blower.The key part of micro porous aeration head is one deck rubber film covering its surface, is uniformly distributed a lot of micropore above.After fan starting, by pressurized air by Cemented filling in micro porous aeration head, rubber film is upspring under the effect of the pressure, and micropore above opens, and gas is discharged in water by micropore.After blower fan cuts out, when losing pressure, rubber film fits on the surface of micro porous aeration head again, and micropore closes.
In normal use procedure, micro porous aeration head can damage.1, under long-time pressure effect, rubber film is caused to upspring for a long time damage of following the string; 2, blower fan frequently opens and closes, cause rubber film frequently upspring retract damage; 3, because some special material in waste water is corrosive to rubber, rubber film is caused to damage; 4, other situations cause rubber film to damage.
No longer will form small bubble by the micropore release above rubber film by the pressurized gas of this aeration head after rubber film damages, but directly emerged by breakage, form larger bubble.Reduce gas liquid interfacial area, air utilization ratio declines, and the dissolved oxygen in waste water reduces.Other aeration head near the simultaneously damage of an aeration head also can have influence on, because pressurized air will discharge from the breakage that pressure is less, like this, rubber film is upspring owing to not having enough pressurized air by other aeration head, causes aeration head aeration deleterious.Therefore need to keep in repair aeration head, existing micro porous aeration head is all fixed on substrate at the bottom of pond, can not move.There is waste water inside pond simultaneously always.Directly cannot keep in repair after aeration head damages, and can only dive under water at the bottom of pond or by the water in pond and find time, keep in repair, the cost and risk of therefore keeping in repair an aeration head is all very large.
Summary of the invention
The object of the invention is to solve aeration head in prior art cannot directly keep in repair after damaging, the problem of carrying out keeping in repair of can only diving under water at the bottom of pond or the water in pond is found time, provide one automatically to float microporous aeration device.
The technical scheme realizing the object of the invention is: one floats microporous aeration device automatically, comprise and be erected at aeration supervisor on the body water surface of pond, through take-off pipe aeration branch pipe is responsible for aeration, the lower end of aeration branch pipe is fixedly connected with a reducer tee, its another two ports connected electromagnetic valve one and " L " type aeration tube respectively; Described magnetic valve one is fixedly connected with floating airbag, and floating airbag airbag mouth place is fixedly installed pressure transmitter one; Described " L " type aeration tube one end connects reducer tee the other end connected electromagnetic valve two, and magnetic valve two is fixedly connected with micro porous aeration head, micro porous aeration head is provided with pressure transmitter two; The end of described aeration branch pipe is fixed with sinking metal block, described aeration branch pipe is positioned at reducer tee and has part flexible pipe or whole section for flexible pipe with upper part.
The present invention floats microporous aeration device automatically, and a kind of scheme aeration branch pipe is positioned at reducer tee with whole section of upper part for flexible pipe.
The present invention floats microporous aeration device automatically, and aeration branch pipe described in another kind of scheme is being responsible for below joint with aeration, more than reducer tee has one section of flexible pipe, and the length of this flexible pipe meets and can emerge when micro porous aeration head floats.Now, when in aeration tank, arm is more, when there is the damage of multiple aeration head, long flexible pipe can be wound around simultaneously, adopts part hose construction, effectively reduces winding.
The present invention floats microporous aeration device automatically, described reducer tee place can fixedly mount a wireless signal transceiver, so just by this transceiver, signal can be sent to controller PLC, when not adopting wireless signal transceiver, for by wired transmission, transmission line is fixed in aeration supervisor and aeration branch pipe.
The present invention floats microporous aeration device automatically, and described flexible pipe is nonrigid plastic pipe or rubber hose.
During use, aeration main pipeline suspension frame is located at the top of aeration tank; The flexible pipe that aeration branch pipe adopts rubber etc. to make, one is connected on supervisor, and other end is provided with reducer tee, and threeway one connects L-type aeration tube and micro porous aeration head; L-type aeration tube is equipped with magnetic valve one, pressure transmitter one and sinking metal block, magnetic valve two, pressure transmitter two and floating airbag are equipped with in threeway other end;
During normal operation, magnetic valve two is opened, and magnetic valve two is cut out.When micro porous aeration head occurs damaged, pressure transmitter two perceives pressure and reduces, and send signal to PLC, PLC, by shut electromagnetic valve two, opens magnetic valve one, inflates inside floating airbag.When being inflated to specified pressure, pressure transmitter one, sends to PLC by signal, and PLC, by shut electromagnetic valve one, now damages aeration head under the buoyancy of floating airbag, floats to surface, pond, carry out keeping in repair and changing.
After having keeped in repair, air is wherein discharged by the blow-off valve opened on floating airbag, pressure transmitter one perceives pressure change, give PLC by signal, PLC opens magnetic valve two, and magnetic valve one is still in closing condition, aeration head is put into pond, under the action of gravity of sinking metal block, aeration head sinks at the bottom of pond, starts normally to work.
The present invention has positive effect: (1) uses device of the present invention when damaging appears in aeration head, do not need to change an aeration head by emptying for whole pond water, reduce difficulty and the workload of maintenance, do not need to send frogman to dive as the bottom carries out changing the aeration head damaged, reduce the danger coefficient of maintenance yet; (2) aeration branch pipe adopts whole section of flexible pipe or part hose design, adapts to different aeration tank environment.
