Abstract

The utility model aims to provide a filter center tube, which is characterized by comprising an outer tube wall with a circular cross section, and an inner tube wall with a hexagonal cross section. A tube wall is arranged between the outer tube wall and the inner tube wall, the inner tube wall encloses to form a tube cavity, fluids can flow through the tube cavity, and a plurality of small holes penetrating through the tube wall are arranged on the tube wall. A conventional circular inner wall of the filter center tube is improved into a hexagonal design, the space in the tube can be increased by means of external tangency of an inner circle by a hexagon, the thickness of the tube wall is reduced, the water permeability of the center tube is improved, the flowability of the fluids in the tube cavity is enhanced, the strength of the center tube is enhanced, and the water yield of filtering equipment is improved.

Description

A kind of filter center pipe

Technical field

The utility model relates to a kind of tubing, is specifically related to a kind of filter center's pipe that is used for reverse osmosis equipment.

Background technology

Apply in the seawater desalination system along with reverse osmosis technology is increasing; Effect as the central tube of the important parts that catchment of reverse osmosis equipment shows important especially, the directly reflection and influence the task performance of reverse osmosis equipment of the size of the withstand voltage and ability of catchmenting of central tube.In order to strengthen central tube intensity, need to increase the wall thickness of central tube usually, but increase the wall thickness of central tube, will inevitably cause seriously reducing the ability of catchmenting of central tube.Fast development along with water treatment market; Therefore requirement to reverse osmosis equipment task performance, aquifer yield, salt rejection rate constantly promotes, and researches and develops that resistance to pressure is stronger, the central tube of the better effects if of catchmenting, is even more important with the pressure energy power of passing through of lifting means, the central tube that improves equipment effectiveness.

Summary of the invention

The utility model is accomplished in order to solve deficiency of the prior art, and the purpose of the utility model provides filter center's pipe that a kind of resistance to pressure is strong, catchment effective.

The technical scheme of the utility model is:

A kind of filter center pipe; It is characterized in that: it has cross section for circular outer tube wall and cross section are hexagonal inner tubal wall, is tube wall between said outer tube wall and inner tubal wall; Said inner tubal wall surrounds the tube chamber that can supply fluid to flow through, and said tube wall is provided with several apertures that runs through tube wall.

Further, said hexagon is a regular hexagon.

The utility model is improved as the employing hexagonal design by the circular inner wall of routine; Through the circumscribed hexagonal mode of interior circle the space in the pipe is increased; Pipe thickness reduces; The water penetration of central tube, the flowability of the intraluminal fluid of enhancing are provided, and the intensity of central tube increases the aquifer yield of raising filter plant.

The specific embodiment

Below in conjunction with the specific embodiment a kind of filter center pipe of the utility model is carried out detailed description.

Filter center's pipe of the utility model has cross section and is circular outer tube wall 1; With cross section be hexagonal inner tubal wall 2; Tube wall 4 for processing between outer tube wall 1 and inner tubal wall 2 by the counter-infiltration material; Inner tubal wall surrounds the tube chamber 3 that can supply fluid to flow through, and on tube wall 4, is provided with several apertures that runs through tube wall 5.Aperture 5 is used to make water through getting into tube chamber, has the function of catchmenting.In general, therefore the hydraulic pressure outside the central tube, catchment and can get in the tube chamber through the aperture on the tube wall greater than the pipe internal pressure.At needs central tube is washed when cleaning, intraluminal pressure is then greater than the outer hydraulic pressure of pipe, thereby can the impurity that stop up aperture be washed away.

Further, said hexagon is a regular hexagon.

In this example; Cross section is that hexagonal inner tubal wall can also suitably be adjusted size and is out of shape slightly; Carry out experiment and technology adjustment repeatedly as required, after the contraction data statistical analysis, can be in the specification of needs with the size Control of the size of the outer tube wall of central tube and inner tubal wall.

The utility model is changed the design of conventional circular inner tubal wall; Inner tubal wall is adopted hexagonal design; The space passed through of supplied fluid in the pipe is increased greatly, and hexagonal design can also promote the intensity of central tube under the prerequisite of the thickness that does not increase tube wall, improve its resistance to pressure; Improve the water penetration of central tube, the flowability of the intraluminal fluid of enhancing, thereby improve the aquifer yield of filter plant.Compare with the similar tubing of the circular cylindrical cross-section of routine, under the constant situation of other conditions, can be than the water flow velocity in the raising pipe of limits, the ability of catchmenting improves more than 25%.

Above-mentionedly only several kinds of specific embodiments in the utility model are explained; But can not be as the protection domain of the utility model; Every equivalence of having done according to the design spirit in the utility model changes or modifies, and all should think the protection domain that falls into the utility model.
