Abstract
The utility model discloses a kind of coagulant add-on systems for extending the treating nature water cycle of operation.Coagulant add-on system provided by the utility model includes coagulant intake gate, metering pump access doors, y-type filter, metering pump, metering pump outlet portal and drug feeding pipeline, further includes flushing water pipeline and pressure gauge；The flushing water is formed with pipeline by being located at the flushing pipeline of the y-type filter entrance main pipe side and the total door of flushing pipeline, flushing water, flushing gate 4, flushing gate 21 and the sewage door positioned at the metering pump exit main pipe side.Coagulant add-on system provided by the utility model can effectively remove pump inlet and outlet and pipeline deposit, make the dosing of coagulant system continuous-stable, extend the cycle of operation for the treatment of nature water, have important application value by square impact, back-flushing backwashing manner.
Description
Technical field
The present invention relates to treating nature water plus coagulant system, more particularly to coagulant it is continuous, stablize dosing, extend former
The water pretreatment cycle of operation.
Background technology
The machinery that treating nature water system generally uses accelerates stirring clarifying basin, need in operational process to add in coagulant with
The impurity such as suspended matter and the colloid in water body are removed, continuous, stable dosing ensures effluent quality clarification.
Since coagulant is impure more in actual moving process, it is frequently occluded pump intake strainer and in drug feeding pipeline
Interior deposition, deposit make line clogging, and dosage is caused to change, and influence clarifying basin effluent quality；Dosing PVC pipeline is easily old
Change, coagulant is adsorbed in inner wall of the pipe, and internal pipe pressure is easily caused to increase or even makes pipeline junction rupture leakage, is influenced
System operation.
In existing medicine system, do not have and consider that drug feeding pipeline blocks, remove the effective way of deposit, pipeline blocks up
All it is manually to clear up after plug, in scale removal process, treating nature water system needs to stop transport.
Invention content
The deposit for coagulant system being added to be generated during dosing it is an object of the invention to solve treating nature water blocks up
The problem of filling in pipeline and strainer, it is intended that the dosing of coagulant continuous-stable extends the cycle of operation for the treatment of nature water.
Main pipe side adds water flushing line before dosing pump intake screen, and opposite side sets a sewage door, dosing pump discharge
Main pipe side installs water flushing pipe additional, to realize square impact/recoil of dosing pump, dosing pump outlet conduit to clarifying basin part dosing
Blowdown work in the flushing of pipeline and flushing process.
Current PVC drug feeding pipelines are substituted using acidproof high-pressure rubber hose, are connected at the both ends of connection using stainless steel, with
Make junction that rubber tube not occur to come off, extend the service life of this rubber tube.
By just washing the water backwashing manner with backwash, can effectively remove pump inlet and outlet and pipeline deposit, by it is continuous,
Stable dosing ensures clarifying basin stable effluent quality, qualification, effectively extends the cycle of operation for the treatment of nature water system.
In order to reach object above, the present invention uses following technical scheme：
1st, tubing is changed：Use acidproof high-pressure rubber hose（Material fluorubber, this rubber tube chemical stability is good, high temperature resistant, resistance to
Aging, good mechanical performance）PVC drug feeding pipelines are substituted, the needs that treating nature water system is run steadily in the long term can be met；
2nd, flushing line is installed additional：Main pipe and dosing pump discharge main pipe install water flushing pipe additional before dosing pump intake screen
And blowoff line, water quality used of making up a prescription need to be higher than or be equal to by rinsing source quality.
Due to the use of said program, the present invention has the following advantages：
1st, using acidproof high-pressure rubber hose, chemical stability is good, high temperature resistant, ageing-resistant, good mechanical performance, can be effective
Extend the service life of dosing pipe；
2nd, main pipe and dosing pump discharge main pipe install water flushing pipe additional before dosing pump intake screen, pass through water flush pipe
The square impact recoil on road, can effectively remove pump inlet and outlet and pipeline deposit, and continuous, stable dosing ensures clarifying basin water outlet
Water stabilization, qualification extend the cycle of operation for the treatment of nature water system.
Description of the drawings
Attached drawing is system schematic, in figure：1. total 4. mistake of door of 2. coagulant intake gate of coagulant intake gate, 3. flushing water
Filter flushing gate 5,6. metering pump access doors 7-10. drug feeding pipeline 11-12. coagulant solution case 13-14. metering pumps

Specific embodiment
Below in conjunction with the attached drawing of the present invention, technical scheme of the present invention is clearly completely described
When dosing pump intake screen 15,16 and dirty stifled metering pump ontology 13,14, open at pump discharge flushing gate 4 and
Wash dirt in pump ontology and strainer is totally closed flushing gate 4 and sewage door 20 by sewage door 20 afterwards；Pump intake is opened to rinse
Water pump rinses residual dirt to mechanical accelerating purifying pool；
When drug feeding pipeline dirt is stifled, metering pump inlet 4 or metering pump discharge flushing gate 21 can be arbitrarily opened, by dirt
It rinses to mechanical accelerating purifying pool.
The operation principle of the utility model
Coagulant dosing pump discharge is equipped with pressure gauge 19, under normal operating conditions, when pressure gauge instruction rises to setting
Pressure（Pressure difference is more than a certain setting value）, illustrate that coagulant drug feeding pipeline deposit needs to rinse, corresponding flushing can be opened at this time
Water valve is rinsed coagulant drug feeding pipeline；
Under normal operating conditions, if the instruction of coagulant dosing pump discharge pressure drops to setting pressure（The big Mr. Yu of pressure difference
One setting value）, illustrate that pump intake strainer and pump ontology deposit need to rinse, corresponding flushing gate can be opened at this time, to coagulation
Agent drug feeding pipeline is rinsed.
Finally illustrate, modify to technical scheme of the present invention or equivalent replacement, without departing from the technology of the present invention
The objective and range of scheme, are intended to be within the scope of the claims of the invention.
