Description
Technical field
The utility model relates to a kind of aerator, particularly relates to a kind of municipal effluent and organic industrial sewage purifying treatment of being applicable to, aeration oxygen replenishing is to improve the tubular type rubber aerator of saturation dissolved oxygen in the sewage.
Background technology
Along with the progress of society, sewage disposal protection environment more and more comes into one's own.Adopting the reliable aerator of technical feature, is the most important condition of guaranteeing waste disposal plant operation steady in a long-term.Municipal effluent principal pollutant composition substantially all is easily by the material of microbiological degradation.In the urban sewage treatment process technical scheme, adopt the aeration aerating culturing micro-organisms that organic pollution materials is decomposed, this ultimate principle all is identical.General all is to take just heavy, aeration, two heavy, the technical process that reflux or discharge; Aeration, the two three-in-one body intermittent aeration technologies of sinking, refluxing or discharging have also appearred in recent years.But municipal effluent belongs to the neutral sewage of biochemical treatment, and Technology requires very not complicated, and the key factor of urban sewage treatment process technical scheme is selecting for use of aerator.
Aeration aerating is urban sewage treatment process most important technical guarantee means in service, also is the dynamic control core of technology operation; In the municipal sewage treatment working cost, the power consumption proportion is about 80%, and the aeration aerating energy consumption accounts for about 80% of device total output consumption again; This shows selected aerator and the technology critical role in the urban sewage treatment process technical scheme.
Because blast aeration dynamic efficiency height, three-dimensional gas distribution performance is good, uses comparatively general at present.The terminal key equipment of blast aeration is aerator, and development situation that therefore we can say aerator has just been represented the state of the art of blast aeration.Because the technology theory that the aeration tank is relevant calculates, fundamental point is exactly the aeration coefficient of oxygen utilization, thereby the technological assessment emphasis that causes having occurred aerator concentrates on coefficient of oxygen utilization, has also caused occurring hole diffusion---the phenomenon that exhaust apertures is more and more thinner.
Theoretically, the functional efficiency of equipment is high more good more, if but this functional efficiency does not have rational technical support, and then it is insecure certainly.That yes is high more good more for " coefficient of oxygen utilization " of aerator, if but realize that this efficient is is cost to reduce engineering reliability, obviously be problematic.
What is called has the hole diffusion of " bleeding edge " at present, the aerator oxygen transfer rate is reached more than 30%, but be nothing but that exhaust apertures attenuates more, and the air inlet dedusting requires strict more, and resistance loss increases more; Promptly realize that so that technology more is unreasonable its result of practical application also can only be that technology is more unreliable.
Summary of the invention
At the problems referred to above, main purpose of the present utility model is to provide a kind of tubular type rubber aerator to be applicable to municipal effluent and organic industrial sewage purifying treatment, aeration oxygen replenishing, to improve the tubular type rubber aerator of saturation dissolved oxygen in the sewage, the utility model solves above-mentioned technical problem by following technical proposals: a kind of tubular type rubber aerator, it comprises left side pipe, right pipe, pipe clamp, aeration film pipe, gas distribution pipe, be enclosed within the internal lining pipe of aeration rubber the inside, it is characterized in that: described aerator also comprises the solarization air cap that is distributed on the described aeration film pipe, be distributed in the air slot on the internal lining pipe, described internal lining pipe is a hollow, the centre of described gas distribution pipe is provided with aperture, described left side pipe and right pipe respectively with described gas distribution pipe by being threaded, described pipe clamp is installed in left side pipe and right pipe and goes up a end away from described gas distribution pipe.

Some tubular type rubber aerators are connected with strut member by web member, and strut member adopts hollow, water-filling form, greatly reduces the buoyancy of aerating system in water.
Be implementation procedure of the present invention below:
Tubular type rubber aerator described in the utility model is when aeration, pressure air is entered by the aperture on the gas distribution pipe, by being distributed in the air slot on the internal lining pipe, between aeration film pipe and supporter, form ring-shaped air chamber, aeration film pipe is heaved, and air is opened solarization air cap to the water body aeration by aeration film Guan Shangke; Stop air feed, aeration film tubular elastic shrinks to be held tightly on supporter, and solarization air cap is the closed pore with the resilience contraction also, stops water body to flow backwards and enters air slot.
