Description
Technical field
The utility model belongs to sewage treatment unit technical field, is primarily related to a kind of sanitary sewage disposal system
The aerobic feeder of system.
Background technology
In sanitary sewage disposal engineering, aerobic treatment is a kind of relatively advanced method for innocent treatment；Good
During oxygen biochemical treatment, aerobic microbiological is utilized（Including aerobic-anaerobic microbe）Biological generation is carried out under conditions of with the presence of oxygen
Thank with the organic substance in sewage of degrading；
At present, the oxygen supply that aerobic biochemical ferments in sewage disposal system generally uses air blower to its non-interruptible supply
Air realizes biochemical fermentation；Basic configuration is that two (ensureing that 1 is standby with 1) power are 5.5KW or so air blower；This oxygen supply side
The problem of formula is present mainly has：1st, power consumption needed for motor operation is annual actual in more than 100000KWH, using grid electricity fee cost compared with
It is high；2nd, motor and blower fan belong to equipment of making a connection, and fault rate is higher, need regular carry out Maintenance and Repair, including filter screen cleaning
Replacing, motor bearing lubrication replacing etc. are, it is necessary to which certain maintenance maintenance cost is used as guarantee.
Utility model content
Thus the purpose of utility model produces, and proposes a kind of aerobic feeder of domestic sewage processing system, the aerobic confession
Device of air is changed to be supplied by compressed air by originally will persistently be supplied by determining frequency blower fan, not only ensures the normal of biochemical reaction
Air demand, and power consumption can be greatly lowered, use cost is reduced, while by on-line control air demand, to biochemistry
Process has more effectively regulation and optimization function.
Utility model realizes that above-mentioned purpose is adopted the technical scheme that：A kind of aerobic feeder of domestic sewage processing system
It is in original main aerobic treatment being made up of A grades of biochemistry pools, O grades of biochemistry pools and original system air blower delivery trunk road
On architecture basics, compressed air supply air line is set, and entrance point and the compressed air of the compressed air supply air line take
Gas point connection, the port of export be connected with the original system air blower delivery trunk road, the compressed air supply air line into and out of
Mouth end is respectively installed by one valve.
Utility model installs a pressure gauge additional in the port of export of compressed air supply air line.
Utility model is directed to the relevant industries for having the stable air supply source of compressed air, is set at design and construction initial stage or operation later stage
Standby transformation can use this practical technique, you can save equipment purchase, periodic maintenance and operation power consumption, cost-effective
Effect is notable；Supply source of the gas is become into pressure adjustable, the wider array of advantage of tolerance adjustable range, while can basis after the restoration and reuse
Industry-by-industry installs timing, pressure regulation, the small-sized control loop of segmentation supply additional with the concrete condition in compression ring border, you can reach different fields
The technique of conjunction needs, therefore application prospect is more broad.
Utility model possesses advantages below：
1. energy-saving and no increase compressed air operating cost
To large and medium-sized enterprise, Air Compressor Equipment is run-on facility, and air demand pressure stability, and tolerance is sufficient；In dirt
Water treatment system can be regarded as one and use gas branch road, and consumption tolerance is few, does not have extra operating cost to system；It can stop after transformation
With original frequency motor, power consumption can be greatly lowered.By taking 5.5KW motors as an example calculate, year using electricity wisely 100000KWH with
On, power cost saving consumes 50,000 yuan or so.
2. it can still ensure to reach the air supply requirement of original frequency motor, it is ensured that biochemical reaction is normally carried out
The wind supply quantity that frequency motor is determined in former design calculates pressure-reducing valve, regulating valve, the air supply pipe needed for being changed to after compressed air
Footpath etc., so that control air quantity can reach the air demand needed for former design biochemical reaction, so as to ensure that biochemical reaction is normally carried out.
3. air demand and pressure are from being quantitatively changed into adjustable
Former feeder is with the offer of frequency motor is determined, so institute's wind supply quantity, pressure are consistent all the time, to biochemical reaction oxygen demand
It can not be adjusted；And plant area's compressed air is installed additional after pressure-reducing valve, regulating valve, air demand is set then to be realized by regulating valve online
Regulation, can technically have more effectively regulation and optimization function to biochemical process.
4. improvement expenses is low, it is easy to implement, and can save equipment investment, maintenance and energy consumption cost
Device is used instead after compressed air, can be saved two and be determined frequency motor, the equipment purchase expense of mating electrical control system；
Manpower needed for plant maintenance, spare part expense input are avoided, zero failure rate is realized, while also vanishing is consumed electric energy therewith.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1st, compressed air takes gas point, 2, compressed air supply air line, 3, original system air blower delivery trunk road, 4,
Valve, 5, pressure gauge, 6, air blower output pressure, 7, A grades of biochemistry pools, 8, O grades of biochemistry pools.
Embodiment
Accompanying drawing, the utility model is further described by way of embodiment.
As shown in Figure 1：The aerobic feeder of domestic sewage processing system described in the present embodiment is original main by A grades
On the architecture basics for the aerobic treatment that biochemistry pool 7, O grade biochemistry pool 8 and original system air blower delivery trunk road 3 are constituted, separately
Compressed air supply air line 2 is provided with, the compressed air supply air line 2 uses caliber DN32 galvanized pipes, makees ground after preservative treatment
Bury and lay；Its entrance point takes gas point 1 to connect with compressed air, the port of export and original system air blower delivery trunk road 3 are connected, original system
Unite the caliber DN76 of air blower delivery trunk road 3；One DN32 valve is respectively installed at the import and export end of compressed air supply air line 2
4, it is V1, V2 respectively；It can be adjusted as the either on or off and pressure of the branch road；In the port of export of compressed air supply air line 2
Install a pressure gauge 5 additional（PNEW）, for adjusting the supply gas pressure of compressed air supply air line with reach original system air blower export
Pressure 6（Poriginal）, so as to reach former design gas consumption（Also it can be calculated and be managed needed for after transformation according to design technology institute air demand
Footpath pressure）Now record PNEWFor the operation standard pressure of sewage aerobic air supply system, original system supply can be set after the completion of transformation
It is standby bypass, processed offline；For example：Original system air feed main pipeline caliber is DN76, main pipe pressure Poriginal=0.04MPa；Transformation
Steam line caliber is DN32, and control valve makes air blast main line pressure reach 0.04MPa, now record transformation loine pressure PNEW=
