Abstract
The invention discloses a reflow-stirring chemical adding process method and device, belonging to the field of water treatment. The reflow-stirring chemical adding process method is as follows: a common pump is used as a chemical adding pump, and matched with a flow meter to replace a metering pump for metering and adding a chemical, partial liquid from a pump outlet reflows and returns to a chemical dissolving tank, and the liquid in the chemical dissolving tank is stirred by using kinetic energy of the reflowing liquid, and thus a mechanical stirring device in the chemical dissolving tank is replaced. The method and the used device have the characteristics of low equipment cost, convenience in maintenance, corrosion resistance, long service life, simplicity in operation, and the like.
Description
Technical field
A kind of return stirring dosing processing method and device, belong to water treatment field.
Background technology
Water is the basic substance that the mankind and all living things are depended on for existence.In the situation that water resources lacks day by day, water resource pollution has become the main restricting factor of socio-economic development.The many areas of China, various complicated factors cause many water bodys to be subject to severe contamination, have further aggravated water resources shortage.
Chemicals dosing plant is mainly used in the processing such as feedwater, stove water, recirculated water, waste water, also can be used for the industries such as oil, chemical industry, environmental protection, waterworks.Chemicals dosing plant is generally all furnished with stirring system, medicine system.Chemicals dosing plant is in the past all to adopt volume pump dosing, and cost is high, and maintenance cost is high; Because molten medicine-chest uses as explosive box, precipitate for fear of use procedure Chinese medicine, necessary additional agitator, and the agitator in molten medicine-chest moves together with dosing pump, agitator just must keep higher power, rapid stirring liquid medicine just can make liquid medicine mix, and has so just increased power consumption.
Summary of the invention
The object of this invention is to provide a kind of return stirring dosing processing method and device.
The technical solution used in the present invention is:
A kind of return stirring dosing processing method and device, the method is for using conventional pump as dosing pump, coordinate to replace volume pump to carry out dosing with under meter, the partially liq of dosing pump outlet refluxes and returns to drug dissolving tank, utilize the kinetic energy of this withdrawing fluid to stir the liquid in drug dissolving tank simultaneously, thereby replace the mechanical stirring device in drug dissolving tank; The method equipment therefor comprises drug dissolving tank, dosing pump, under meter, vacuum breaker; Drug dissolving tank is connected with dosing pump import by drug-transmitting pipe, and dosing pump outlet is connected with under meter import on the one hand, is connected to drug dissolving tank by return line simultaneously; Under meter outlet is connected to dispensing point by vacuum breaker.
Described dosing pump, under meter and pipeline, select corresponding material according to the acid-basicity of solution or corrodibility, selects corresponding model according to uninterrupted.
Described under meter is mainly spinner-type flowmeter, magnetic flow meter or turbo flow meter.
Described dosing pump is mainly impeller pump, reciprocation pump or toothed gear pump.
The advantage of the method and device is: 1, use conventional pump as dosing pump, and expensive volume pump in the alternative traditional technology of flow meter use, can greatly reduce equipment cost; 2, the liquid that utilizes dosing pump outlet to reflux stirs liquid in drug dissolving tank, both can save the use of mechanical stirring device in drug dissolving tank, reduces investment, reduces energy consumption simultaneously and realizes the even mixing of liquid.3, adopt under meter, liquor strength is constant, adds accurate, steady, simple to operate, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is a kind of return stirring dosing processing method of the present invention and apparatus structure schematic diagram;
In figure, 1, drug dissolving tank; 2, dosing pump; 3, under meter; 4, dosing pump import; 5, dosing pump outlet; 6, return line; 7, vacuum breaker.
Embodiment
Referring to Fig. 1, a kind of return stirring adding method thereof of the present invention and device, comprise with conventional pump 2 as dosing pump, coordinate to replace volume pump to carry out dosing with under meter 3, drug dissolving tank 1 is connected with dosing pump 2 imports 4 by drug-transmitting pipe, and dosing pump outlet 5, on the one hand by being connected with under meter 3 imports, is connected to drug dissolving tank by return line 6 simultaneously, utilize the kinetic energy of this withdrawing fluid to stir the liquid in drug dissolving tank 1, under meter 3 exports by chemical feed pipe and connects vacuum breaker 7 to dispensing point.
Close under meter, open dosing pump, drug dissolving tank 1 liquid is back to drug dissolving tank 1 through return line 6, utilizes the kinetic energy of this withdrawing fluid to stir the liquid in drug dissolving tank 1, and medicament and water are stirred.Turn-on flow rate meter, adjusts flow, and liquid is exported through chemical feed pipe and connected vacuum breaker 7 to dispensing point by under meter 3, and another part continues to be back to drug dissolving tank 1 by return line 6, and the liquid in drug dissolving tank 1 is stirred, and guarantees that medicament fully mixes with water.
