Description
Technical field
The utility model relates to the paper industry technical field of sewage, is specifically related to a kind of sewage disposal biochemistry pool micro-hole aerator diaphragm-operated on-line cleaning device.
Background technology
To waste paper carry out size degradation, making beating, when manufacturing paper with pulp again, the paper organic waste water of generation must discharge after treatment.In treating processes, sewage needs through operations such as a heavy pond precipitation, biochemistry pool processing, second pond precipitations.Wherein, the sewage disposal biochemistry pool is provided with aerating system so that be microorganism supplemental oxygen in the biochemistry pool, and way is to blast air by supply air lines such as gas blower, branch gas bags to biochemistry pool bottom aerator.At present, what generally adopt in the sewage disposal biochemistry pool is the membrane-type microporous aerator, and it mainly is made up of the rubber diaphragm of diaphragm back up pad and band micropore.Rubber diaphragm is spherical crown shape Bao Meng on back up pad, and back up pad is communicated with supply air line by the hollow bolt that the center is provided with.
Because the aerator diaphragm is immersed in the biochemistry pool sewage, wastewater temperature higher (generally more than 25 ℃) in the biochemistry pool, and contain calcium, magnesium ion and carbonate, the light root of carbonic acid, sulfate radical etc. in the water, so very easily fouling generates throw outs such as lime carbonate, magnesiumcarbonate, calcium sulfate on rubber diaphragm, cause the rubber diaphragm micropore to stop up and normal aeration.For head it off, need sewage in the frequent emptying biochemistry pool, change the diaphragm on the aerator then, labour intensity is big, production efficiency is low, and can make cost of sewage disposal improve greatly because of the obstruction explosion in case change untimely aerator diaphragm.
The utility model content
Technical problem to be solved in the utility model provides a kind of sewage disposal biochemistry pool micro-hole aerator diaphragm-operated on-line cleaning device, it is simple in structure, can reduce effectively or prevent that the aerator diaphragm from the micropore phenomenon of blocking in use taking place, thereby reduce cleaning diaphragm-operated labour intensity, improved sewage treating efficiency, reduced cost of sewage disposal.
For solving the problems of the technologies described above, the technical solution of the utility model is: sewage disposal biochemistry pool micro-hole aerator diaphragm-operated on-line cleaning device, comprise supply air line and several micro-hole aerators that are arranged on the described supply air line, described supply air line is provided with air intake valve, described supply air line is provided with the online adding set of acid solution, and the online adding set of described acid solution is positioned at the downstream position of described air intake valve.
As a kind of optimized technical scheme, the online adding set of described acid solution comprises the outer pillar that is fixed on the described supply air line, be provided with in the described outer pillar and add acid tube, the described lower openings that adds acid tube extends in the described supply air line inner chamber, and described outer pillar and the described upper opening place that adds acid tube are fixed with rubber sealing device.
As a kind of optimized technical scheme, described rubber sealing device is a rubber pad.
As a kind of optimized technical scheme, the described acid tube that adds is a plastic hose.
After having adopted technique scheme, the beneficial effects of the utility model are: because the utility model supply air line is provided with an online adding set of acid solution, it comprises the outer pillar that is fixed on the supply air line, be provided with in the pillar outside and add acid tube, the lower openings that adds acid tube extends in the supply air line inner chamber, and pillar is fixed with rubber sealing device with the upper opening place that adds acid tube outside.The effect that outer pillar plays is fixing, protection adds acid tube; Add acid tube and adopt plastic hose, can prevent effectively by acid liquid corrosion; Rubber sealing device can repeated localised puncture use.In adding acid tube, add acidic solution with syringe by rubber sealing device, acidic solution preferentially adopts formic acid solution, open the air intake valve on the supply air line simultaneously, make formic acid run into air and form a large amount of acid mists, the acid mist small droplets is adsorbed under the induced effect of air around the diaphragm micropore blasting, thereby make scale forming matters such as near the lime carbonate micropore, magnesiumcarbonate, calcium sulfate and formic acid reaction formation formate be dissolved in the water, thereby avoided micro-hole aerator diaphragm micropore phenomenon of blocking effectively.Therefore this utility model can carry out on-line cleaning to the aerator diaphragm, thereby has reduced cleaning diaphragm-operated labour intensity, has improved sewage treating efficiency, reduced cost of sewage disposal.
