Description
Technical field
The utility model belongs to field of sea water desalting technology, particularly relates to a kind of seawater and brackish water desalination Scale inhibitors chemicals dosing plant.
Background technology
China is the country of a water resources critical shortage.Gross amount of water resources 2.81 tcm, occupy the 6th, the world, but population is 1/4th of world population, and water resources is the 108th, the world per capita, is one of 21 poor-waters country in the world.The particularly beach saline land area in the north, Freshwater resources are in great shortage, are one of most water-deficient areas of China, but seawater and brackish water aboundresources, seawater and brackish water desalination are one of fundamental ways solving coastland water scarcity.
Current Application comparison widely seawater and technique of desalinating saline water is reverse osmosis method, its principle is in water salty, impose the pressure larger than naturally osmotic pressure, infiltration is carried out round about, water molecules in former water is pressed onto the other side of film, becomes pure water, thus reach the object except the middle salinity that anhydrates, therefore, it is possible to effectively remove the dissolved salts, colloid, microorganism, organism etc. in water, clearance is up to 97 ~ 98%.At present, except Gulf states, America, Asia and Europe, big-and-middle production-scale device is all first-selection with reverse osmosis method.Reverse osmosis unit, the ion range mainly in separation solution, without the need to heating, more do not have phase transition process, the method energy consumption therefore than traditional is low.
In actual motion, while the other side water molecules in former water being pressed onto film becomes clean water, membrane element fouling and clogging is very easily caused due to the significantly increase of saltiness in dense water side, and impact normally uses, and shortens the work-ing life of reverse osmosis membrane.In order to address this problem, method general at present adds chemical scale-inhibitor, changes incrustation ion state in water, make into dirty probability and decline to a great extent by chemical substance.
The Scale inhibitors chemicals dosing plant of current use is comprise medicine-adding bin and dosing pump mostly, by suction and the pressurization of force (forcing) pump, is joined in raw water tubes by the Scale inhibitors in medicine-adding bin by chemical feed pipe.In concrete use, by the impact of dosing pump performance, chemical feeding quantity is unstable, and Scale inhibitors can not fully mix with former water, also needs in addition to consume certain electric energy.
Utility model content
The purpose of this utility model is to provide a kind of seawater and brackish water desalination Scale inhibitors chemicals dosing plant, and chemical feeding quantity is stable, adjustable, avoids occurring that Scale inhibitors mixes uneven problem with former water, and saves electric power resource.
The utility model realizes like this, a kind of seawater and brackish water desalination Scale inhibitors chemicals dosing plant, comprise raw water tubes, described raw water tubes is provided with raw water pump, described raw water tubes comprises the first former water arm and the second former water arm that are connected with the water side of described raw water pump respectively, described first former water arm is communicated with mixing tank with the second former water arm, described first former water arm is provided with first flow variable valve, described second former water arm is provided with second adjustable valve, described first former water arm is provided with venturi-type eductors, described venturi-type eductors comprises entrance end, ejection end and injection suction side, described entrance end is communicated with described first former water arm respectively with ejection end, described injection suction side is communicated with Scale inhibitors placing box by drug-transmitting pipe.
Improve as one, described drug-transmitting pipe is provided with for Scale inhibitors from Scale inhibitors placing box to the check valve of venturi-type eductors uniflux.
As improving further, be provided with whipping appts in described mixing tank, described whipping appts is provided with wind power transmission wind mechanism.
Improve as one, described whipping appts comprises stir shaft, and described wind power transmission wind mechanism comprises main drive shaft, and described main drive shaft is provided with turned blade, and described main drive shaft and described stir shaft are in transmission connection.
Owing to adopting technique scheme, the beneficial effects of the utility model are:
Because raw water tubes comprises the first former water arm and the second former water arm be connected with the water side of raw water pump respectively, first former water arm is provided with venturi-type eductors, venturi-type eductors is communicated with Scale inhibitors placing box, raw water pump runs and makes former current in the first raw water tubes through venturi-type eductors, form negative pressure in venturi-type eductors and suck Scale inhibitors, Scale inhibitors mixes with former water and flow in mixing tank, avoid occurring that Scale inhibitors mixes uneven problem with former water, and saving electric power resource, the stable chemical feeding quantity that makes of venturi-type eductors is stablized in addition, and the first former water arm and the second former water arm are provided with first flow variable valve and second adjustable valve, the flow and flow velocity that flow through in the first former water arm is regulated by regulating first flow variable valve and second adjustable valve, and then regulate the chemical feeding quantity of Scale inhibitors, regulative mode is simple.
Supply Scale inhibitors from Scale inhibitors placing box to the check valve of venturi-type eductors uniflux because drug-transmitting pipe is provided with, avoid former current direction Scale inhibitors placing box.
Owing to being provided with whipping appts in mixing tank, ensure that Scale inhibitors mixes with Yuan Shui, whipping appts is provided with wind power transmission wind mechanism, can make full use of the weather condition that coastal region is windy, the conservation of power energy.
Because whipping appts comprises stir shaft, wind power transmission wind mechanism comprises main drive shaft, and main drive shaft is provided with turned blade, and main drive shaft and stir shaft are in transmission connection, and structure is simple, and working service is convenient, and cost is low, and result of use is good.
