The invention relates to the field of magnetic filtration of process fluids (TJ), lubricating and cooling liquids, cleaning solutions and can be used in the Metalworking industries in the processing of metals by pressure, cutting and rolling.

There is a method of magnetic separation fluid, implemented by a device for Magnetic filter separator (see AC No. 915897. CL. B01D 35/06, VS 1/00. Publ. 30.03.1982, bull. No. 12), namely, that the removal of the magnetic fluid inclusions is due to the deposition of the last magnetic rods, arranged coaxially to the movement of the purified liquid, and regeneration wash deposited on the magnetic cores of the magnetic impurities is carried out by the pressure of the fluid directed perpendicular to the magnetic cores of the tubes arranged coaxially around the magnetic cores.

For reasons that impede the achievement of specified following technical result when using the known method is that liquid is separated in the filter housing in the turbulent regime, which significantly reduces the quality of its cleaning and regeneration wash deposited on the magnetic cores of the magnetic inclusions, carried out by the pressure of the fluid directed perpendicular to the magnetic cores of the tubes arranged coaxially around the magnetic core is, ineffective due to the fact that the basic flow of regenerative fluid in the housing is directed downward axial magnetic rods. While the main flow of regenerative fluid changes the force vector flushing and thus is not fully guaranteed removal of magnetic impurities with the magnetic rods.

It should be noted that in the case of use as a regeneration fluid the cleaned fluid, the challenge further purification regeneration fluid, thickening and dewatering of sludge product, which is not solved in the frame of the specified author's certificate.

Furthermore, the design of the known device does not allow the use of powerful magnets, magnetic rods of considerable length and positioning of the magnetic cores close to each other because the magnetic forces due to the different polarities contribute to the attraction of the magnetic rods to each other, and ultimately "glueing" them together.

A more efficient way of cleaning fluid and thickening sludge product is solved in a device of the Magnetic separator (see patent No. 2207913. CL. B01D 35/06, VS 1/00, SM 175/04. Publ. 10.07.2003, bull. No. 19), namely, that the removal of the magnetic fluid inclusions is due to deposition from the liquid of the magnetic particles on the magnetic cartridges with the subsequent removal of cuttings from magnitnykh cartridges using Samoyedic elements in the pipeline.

The operation of such devices has shown that the effectiveness of the cleaning liquid from the magnetic inclusions increases with increasing concentration of impurities in the liquid, i.e. the known magnetic separator works well for fluid contamination from 1.0 g/DM3and more, that is not always the case in the treatment systems.

These factors dramatically reduce the quality of the cleaning fluid and limit the device performance cleanup.

The essence of the invention is that the cleaning liquid is carried out in a pressure magnetic separators closed type (NMSS), and the purified liquid is collected in the storage tank and use it as a washing liquid for cleaning NMSSM from the slurry, the resulting sludge is thickened in a magnetic separator of the open type (UITP) and serves on dehydration. The fluid selected in the process of dewatering the slurry product is sent to the capacity of UITP and purified in UITP washing fluid in NMSS.

The device for implementing the method of cleaning liquids and utilization of magnetic sludge is connected, as a rule, the source of contamination of the fluid, the magnetic particles and then through a pump and pipeline fluid supply connected with at least two NMSSM, which, in turn, by means of pipes and valves connected with the tank and the HONEYCOMB, which through a pipeline connected to the filter dehydration. Filter dewatering through piping connected to the tank UITP, which, in turn, through a pipeline connected to the supply line of the liquid at NMSS.

The storage tank via a pump and piping connected to the source of the contamination of the magnetic fluid inclusions and through an adjustable valve connected to NMSS.

The use of the present invention provides the following technical result: improved quality of cleaning fluids, reducing the cost of cleanup, including energy costs, reducing the size of the device.

This technical result in the implementation of the invention is achieved by the fact that the proposed method involves passing the cleaned fluid through a magnetic separator and subsequent dewatering of sludge product.

The peculiarity lies in the fact that the cleaning liquid is carried out in NMSSM, and the purified liquid is collected in the storage tank and use it as a washing liquid for cleaning NMSSM from the slurry, the resulting sludge is thickened in UITP and served on dehydration. The fluid selected in the process of dewatering the slurry product is sent to the capacity of UITP and purified in UITP washing fluid in NMSS.

A device for implementing the act is both the purification of liquids and utilization of magnetic sludge, includes magnetic separators, filter dewatering, storage tank, pipeline, pipelines, valves, pumps.

The peculiarity lies in the fact that the source of contamination of the magnetic fluid inclusions through a pump and pipeline fluid supply is connected with at least two NMSSM, which, in turn, by means of pipes and valves connected with the tank and UITP, which through a pipeline connected to the filter dehydration. Filter dewatering through piping connected to the tank UITP, which, in turn, through a pipeline connected to the supply line of the liquid at NMSS.

The storage tank via a pump and piping connected to the source of the contamination of the magnetic fluid inclusions and through an adjustable valve connected to NMSS.

The device includes:

block cleaning liquid,

block thickening sludge product - B

block dewatering sludge product - Century

Device for cleaning liquids and utilization of magnetic sludge consists of pressure magnetic separators closed type (NSST) 1, magnetic separator open type (UITP) 2, filter dewatering 3, tank 4, the conveyor 5, the pumps 6, 7 and 8, valve 9, 10, 11, 12 and 13, the source of contamination of the liquid - for example, rolling mill 14, tanks for oil 15 and sludge 16, pipe 17...22.

The device operates as follows.

In the cleaning mode. Polluted magnetic fluid inclusions from the rolling mill 14 by the pump 6 through the pipe 17 through the valve 10 is forced into the housing NMST 1. Flowing through the separator in the regime of laminar motion through the lattice, recruited from the magnetic rods, the fluid is cleared from the magnetic inclusions due to the adhesion of the magnetic particles to the magnetic rods. Purified in NMSSM 1 fluid through the valve 12 through the pipeline 18 is discharged into the storage tank 4, where the pump 7 to Truboprovod is pumped to the rolling mill 14.

In the cleaning mode of the device. The accumulation of magnetic sludge on magnetic rods in NMSSM 1 arises the need to wash NSST. In this case, close the valves 10, 12 and open the valve 9, 11 one of NSST 1 (other NMSS work in the cleaning mode). In addition, it opens the valve 13, and the treated liquid from the tank 4 by the pump 7 through the pipe 20 under pressure is fed into the housing NMST 1. Injected into the body NMST 1 liquid (as from this moment the washing liquid) in the turbulent regime washes with magnetic cores magnetic slurry through the pipeline 21 is discharged into the tank UITP 2. It should be noted that the concentration of cuttings in the drilling fluid at this point in 10-100 times higher than the concentration of sludge in the cleaning liquid during the cleaning process. In addition, due to the small flush time (1-2 min) merged volume of washing fluid in the tank UITP 2 is negligible, thus the performance of UITP 2 30-60 times lower total performance NMST 1.

After washing NMST 1 closed valves 9, 11, 13 and open the valve 10, 12.

The cleaning mode of drilling fluid and thickening sludge product.

When this mode in the vessel UITP 2 is cleaned wash liquid from the magnetic sludge with magnetic rods and bottom of the pipeline operation, see "the Magician is any separator", patent No. 2207913). Remote cuttings discharged to the conveyor 5, and a stranger oil into the tank 15. The cleaned wash liquid through line 22 by pump 8 is periodically pumped into the pipe 17 for cleaning in NMSSM GNMS 1.

Thus, the proposed closed-loop system cleaning fluid.

The mode of dewatering of sludge product. From the conveyor 5, the sludge is discharged into the filter dewatering 3, where the moisture content of 25-35% in the tank 16. Squeezed out of the sludge washing fluid through the pipeline 23 is discharged into the tank UITP 2.

Using the proposed clearing device on the first stage NMST 1 with laminar mode of operation improves the quality of cleaning.

No pumps between treatment units, thickening and dewatering reduces the cost of cleaning, including energy costs.

The proposed layout of the devices cleaning, thickening and dewatering reduces the dimensions of the entire system.
