Water intake well is filtered in large-scale seawater self-stip
Technical field
The utility model relates to a kind of Treatment of Industrial Water device, relates in particular to a kind of large-scale seawater self-stip and filters water intake well.
Background technology
Along with the development of society, industrial everdeveloping cause continues to increase the application of water resources.Because of Freshwater resources are limited, so coastal cities are to constantly feeling one's way on the engineerings such as process water seawaterization, sea water desaltination, to solve current fresh water crisis.
At present, known large-scale seawater water intake facilities adopt be that sea bed filters water intake well, surface seawater is directly fetched water and method such as submerged pipeline water intaking, positive effect has been played in the utilization of seawater.But these seawater method for fetching water are subject to the influence of stormy waves, tidal level difference and red tide etc., water quality and water yield instability, especially in the more serious marine site of damage ratio, water intaking water quality is very poor, not only increase the cost of follow-up water treatment, even shortened the work-ing life of follow-up water treating equipment greatly.
Summary of the invention
In order to overcome the deficiency of above technology, the utility model provides a kind of large-scale seawater self-stip filtration water intake well of shortcomings such as the water yield instability of seawater water intake facilities, water quality inferiority in the past that overcome.Its technical solution is achieved in that
Water intake well is filtered in a kind of large-scale seawater self-stip, it is characterized in that comprising water intaking pump house, small-sized hoisting machine, large-scale water intaking pump, rubble well and sterilization algae removal device; Described small-sized hoisting machine is installed in the top of water intaking pump house; Described rubble well location is in the below of water intaking pump house; The periphery of rubble well by rubble grain from inside to outside gradually the metalling of chap encase; The pipeline of described sterilization algae removal device leads in the rubble well; On the borehole wall of described rubble well header is housed; One end of header is positioned at the microlith layer of metalling near the rubble well, and the other end leads to the inside of rubble well; The top station pump base of described rubble well is equipped with large-scale water intaking pump above the water pump base; Described metalling is 4~8 layers; Being covered with bed board around the described water pump base walks on stage; Described small-sized hoisting machine is installed on the slide rail at top of water intaking pump house; Described small-sized hoisting machine is installed on the fixedly suspension system at top of water intaking pump house.
Owing to adopted technique scheme, the advantage that water intake well is filtered in the large-scale seawater self-stip that the utility model provides is conspicuous, it not only can overcome the water yield instability of seawater water intake facilities in the past, the shortcoming of water quality inferiority, and still can obtain the higher seawater of quality in the more serious marine site of damage ratio, seawater there is good coarse filtration effect, can reach antipollution effect, and realize the self-stip function of water intake well by the tidal action of ocean.The seawater water intaking water yield is stable, and water quality is good, compares with other equal water intake facilities, the work-ing life that can reduce follow-up cost of water treatment and improve follow-up water treating equipment.

Embodiment
As depicted in figs. 1 and 2, when the utility model is implemented according to field condition, exploration seawater water intaking ground closes on the marine site, select the place that sea situation is preferable, pollution is less, the depth of water is dark, geologic framework is fit to building construction, build this water intake well, water intake well generally is located at 20~30 meters of water front off sea, and by anti-sea wall or wave protection wall and sea isolation, to reduce the influence of bank factor to the water source as far as possible.When rubble well 5 is built by laying bricks or stones, determine header 7 calibers and quantity according to water withdrawal, and arrange in certain sequence, after rubble well 5 is built moulding by laying bricks or stones, need to form metalling 4 with various varigrained gravel backfill, the rubble granularity is more and more thicker away from rubble well direction, Zong the number of plies can reach 4~8 layers with the quality of seawater quality, each metalling 4 backfills height should exceed maximum water level.The pump house 1 of wherein fetching water is positioned at rubble well 5 tops, and be equipped with small-sized hoisting machine 2 to implement to the walk on stage installation and maintenance of equipment such as 10 of water intaking pump, base, bed board, small-sized hoisting machine 2 can be installed according to the size of facility in the well, it can be installed on the slide rail 12 when water intake well is bigger; Small-sized well then can be equipped with fixedly suspension system in the corresponding position of water intaking pump house 1, and small-sized hoisting machine 2 adopts the mobile hoisting machine.Large-scale water intaking pump 3 is installed on the base 9, is equipped with bed board around it and walks on stage and 10 play the safety precaution effect; This water intake well is transported to follow-up water treatment via rising pipe 11 and implements by intake pipe 6 extracting seawater from rubble well 5.
Water intake well should adopt the lift pump of big flow to carry out well-flushing before use.Also to be generally liquid chlorine sterilization, chlorine dioxide generator or ozonizer device etc. to regularly carrying out disinfection sterilization in the rubble well 5 in the use by sterilization algae removal device 8 to guarantee the requirement of the water quality and the water yield.
The above; it only is the preferable embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
