THE TECHNICAL FIELD

Group of inventions relates to the purification of liquids, mainly drinking water, and more specifically to methods of sorption ability of filtering the liquid through the adsorption-bactericidal material in the domestic environment by gravity without the use of additional sources of pressure to ensure the improvement of sorption and bactericidal treatment and improve the quality of the filtered liquid.

The invention can find application for the treatment of drinking water and other liquids household consumption in the chemical, medical and other industries.

ART

The need for clean drinking water in home conditions, in particular in the final wastewater treatment systems is growing due to increasing pollution of natural water, population growth and increasing quality requirements of water consumed. With the increase in the number of medical and environmental information about what water pollution causes disease, the need to use purified drinking water is obvious.

Typical end water treatment system consists of a container (vessel) the purified liquid in the hole of the bottom part of the bottom which is fixed cartridge filter, providing clean fluid during filtration through the filter by gravity in the downward direction under the action of gravitational forces and collecting purified liquid at below capacity (vessel) of purified liquid. As a cleaning agent from chlorine, organics and other contaminants are most often used filter material based on granular activated carbon.

To hold the particles of sorbent in the filter cartridge to the filter output often set additional filter element with small pores that when liquid flows by gravity from the top down (in the direction of the action of gravitational forces) often clogged the small dust-like particles of granular sorbent. This significantly reduces the resource normal filter operation.

The problem is the visual control of the operation of the filter, as well as control over the amount of purified fluid filter.

It is known, in particular, a device for purification of drinking water, comprising a housing having at least one opening for passing fluid into the chamber formed by the internal space of the housing process water cartridge, and a mechanism for indicating life vodoostanavlivayuschee cartridge (U.S. Patent N 5.536.394, B 01 D 35/143, publ. 16.07.96 year). The display mechanism made in the form of playsega the end-of-life vodoostanavlivayuschee device. After the float will make a specific number of revolutions, it stops in a position where it can be seen through the hole in the hull.

Another problem in the practical use of the known constructions of filters with filtration of a liquid under gravity gravity in the downward direction is the formation of gas and air bubbles inside the filter material. These bubbles are blocking the pores, make it difficult and sometimes even completely prevent the flow of fluid through the filter. To solve this problem, developing a special gazoulavlivayuschie design in the filter, which greatly complicates and increases the cost of construction and limits the scope of applicability of the filters.

A significant disadvantage of the known constructions of filters in which the filter under gravity by gravity from top to bottom, is also the phenomenon of complete drainage of the filter at the end of the filtration process. This limits the possibility for use as filtering and sorbing agents, ion-exchange materials that do not withstand periodic change dehumidification and humidification, and when this mode of operation, cease to function properly.

This filter design is complicated to manufacture, in addition, "channel mode" filter when the liquid profiltruyut through the filter material unevenly on separate channels, leads to the fact that a portion of the purified liquid passes through the filter faster required for effective cleaning time and not well cleaned due to the filtration of the liquid in the filter from the top down.

Thus, there is an unresolved up to this time full of inventive problem is siteline simple devices filtration fluid filtration by gravity under the action of gravitational forces (without additional excess pressure) is performed in the downward direction while supplying the liquid into the filter at the top and the discharge of treated liquid from the bottom of the filter.

But for high-quality cleaning you need to provide filtration of the liquid in the filter in the upward direction to prevent premature clogging of the pores of the filter material, better cleaning and sorption of contaminants, automatic removal of air and gases and preservation of the permanent occupancy of the filter liquid.

Known filters in which the filtering is performed in the upward direction, or require the application of excessive pressure of the water supply network (this limits the scope of applications), or require the use of additional hydrostatic pressure of the liquid column (it is not possible to clear the fluid in the full volume without loss to the creation of additional liquid column), or require the use of more complex structures and devices for arranging the filter in the direction opposite to the action of gravitational forces.

TASKS INVENTIONS

The main technical problem (not allowed until the present inventive task containing technical contradiction), constraining the expansion of industrial cleaning fluids, is that the need for more x and implementation of this principle in the known constructions leads or the complexity (cost) and limit applications purification or loss (unused) portion of the purified fluid.

By supplying the cleaned fluid and discharge of treated fluid inside the housing of the filter module 2 additional layers are permeable hydrophilic material 4. The lower part of the housing of the filter module 2 with holes for the supply of the purified liquid is made of a convex shape, and mating with it the bottom of the tank being cleaned liquid 1 has a concave shape.

In the upper part of the filtering module is made airtight cavity 5 of collecting the purified liquid, soamsawali with means for discharge of treated liquid from the filter module 2, which is made in the form of siphon vessel 6, which is located either inside the housing of the filter module 2 (Fig. 1 to 4, 6, 7) in the form of a siphon pipe 7, or outside the housing of the filter module 2 (Fig. 5, 8) in the form of a siphon tube.

The upper part 10 of the walls of the siphon vessel inside the cavity 5 of collecting purified liquid made serving relatively filtering material 3 (Fig. 1 - 4) and the lower part 9 of the siphon vessel 6 (Fig. 1 to 3, 6, 7) completed serving a relatively lower part of the body of the filter module.

According to another variant of the design of the siphon vessel are in the form located outside the housing siphon trbkiste filter module.

Means for supplying the purified liquid in the filter module 2 is carried out in the form of holes in the bottom, the convex part of the housing of the filter module.

In the tank cleaned liquid 1 in the bottom of the concave part is made a hole by means of a seal, made for example in the form of a sealing gasket 12 and a clamping nut 13, which is tightly fixed filter plug 2 (Fig. 1, 3, 6) through the lower protruding part 9 of the siphon vessel 6.

To start a cycle of p1was above the level of the top of the filter housing. After filling the filter module 2, the cleaned fluid displaces air from the filter material 3 and filling the sealed cavity 5 of collecting the purified liquid in the upper part of the filter module 2 and siphon vessel 6 spontaneously starts the filtering process, the cleaned liquid flow profiltruyut through the filter module in the upward direction and is discharged through the siphon vessel 6 in the capacity of purified liquid 8.

Further liquid is sucked completely from the tank cleaned fluid 1 and profiltruyut through the filter module 2 by gravity in the direction from bottom to top. This provides automatic deletion of all the purified liquid from the tank cleaned fluid 1 due to the siphon effect.

To clean the following portions of the liquid the procedure of lling the cleaned fluid 1 is repeated, or in the process of filtering add additional liquid into the tank cleaned liquid 1. This filter material is constantly filled with liquid and not dried in the intervals between cycles of filtration.

To confirm aramoko technical result of filtration was performed comparative comparison of results of different cleaning solutions through identical sorption capacity filters but in one case (as proposed according to the invention) during the filtration of the liquid in the upward direction, and the other (as in the prototype) in the direction from top to bottom.
