Definitions
- the present invention relates to sludge using magnetic phenomena for get rid of sludge liquids with which they are charged.
- the invention is particularly advantageous for sludge removal of water circulating in a closed circuit in the piping for heating installations. We know that in these installations, corrosion or erosion phenomena mechanical walls of the ducts, result in water of heating gradually loads with sludge which are largely made up of magnetic particles.
- sludge removal devices magnetic applicable to liquids such as water, have magnets that we immerse in water to sludge.
- Such device is described, for example, in the patent document American US 2,693,079. This prior art document explains how the magnetic attraction acts to retain the elements magnetic on the magnet and how it is then extracted liquid and cleaned by scraping.
- the present invention has sought to improve the design of art magnetic sludge removal devices in particular to make them better suited to mounting and to operate on pipes in which the liquid to be sludge normally circulates continuously, as it is the case in particular of water circulation heating installations in closed circuit.
- the invention also aims to allow to easily equip existing installations and facilitate a periodic sludge which is practically carried out without disturbing the operation of the installations, in particular by not requiring disassembly of the device or stopping the heating.
- the present invention therefore proposes to circulate the liquid to be sludged through an enclosure connecting to the pipeline in which it circulates continuously and to pass it, in said enclosure, in the vicinity of non-magnetic walls limiting a housing in which a magnet is mounted movable between a active position in which it operates in magnetic attraction sludge present in the liquid circulating on said walls of the housing and a position for withdrawing from said housing which causes the separation of said sludge, which then falls and advantageously meet by decantation at the bottom of said pregnant.
- a periodic command of a stopping the circulation of the liquid through the enclosure and a synchronized emptying of the enclosure, advantageously after removal magnet, to evacuate the collected sludge we can thus perform periodic maintenance of the enclosure without the intervention of a operator.
- the magnet is generally shaped cylindrical and mounted in vertical sliding in its housing.
- the device according to the invention is then advantageously equipped with means to prevent that by following the lifting movement of magnet out of its housing, the sludge is entrained until the upper part of the enclosure.
- These means allow make sure that any sludge that has been attracted to the magnet and that have accumulated on the walls of his housing be well detached from the walls of the housing from the magnet, without let drag in the movement of the latter.
- They can in particular be constituted by a stop piece, advantageously made of non-magnetic material, fixed inside the cross enclosure of the wall of the magnet housing, in a position that the magnet protrudes when removed.
- FIGS. 1 and 2 show a device for sludge removal 1 according to the invention, which can be used in any liquid circulation heating installation, this liquid being in generated water.
- the device is designed to be interposed on a line for the continuous circulation of the liquid, at which it connects to the side of the liquid inlet and the side of the outlet. More exactly, it is generally mounted in derivation on a main pipeline of the installation, in which the water from heating circulates continuously.
- the demister device itself includes a enclosure 2, providing a determined volume of circulation to the liquid, which is illustrated in the preferred form of a section enclosure cylindrical, arranged vertically, and which has a tube inlet 3 and outlet manifold 4, fitted with valves carrying references 5 and 6 respectively. These valves can be operated manually or mechanically to adjust the flow of liquid through the enclosure. Preferably; it could be solenoid valves.
- the two connecting pipes to the pipes are located in the upper part of the enclosure, in respectively diametrically opposite positions.
- Enclosure 2 is closed at its upper part by a cover 9 which is fixed hermetically, by a mode permanent waterproof assembly, for example by welding, on enclosure 2.
- This cover 9 has a central opening 11 which opens into a vertical cylindrical housing 12 which is fixed, hermetically, on the bottom wall of the cover 9, and of which the lower part is closed.
- This housing 12 is arranged centrally in enclosure 2, vertically along its axis. Its walls are made of non-magnetic material. In operation, the housing 12 is on the path of the flow of the liquid to be sludged, which thus circulates through the enclosure in the annular volume formed around the housing 12, as illustrated by the arrows 13 and 14 in the figure.
- the invention as described here comprises a movable magnet 15, the diameter is determined so that it slides freely in the housing 12 but closer to the walls of this housing.
- the face upper of magnet 15 carries a control rod 16, which is it is incapable of exerting a magnetic attraction effect on sludge conveyed by the liquid to be sludged.
- Its diameter is equal to clearance close to that of the opening 11 of the cover 9, so that it can slide freely in this opening through the cover.
- the diameter of magnet 15 is significantly larger than the diameter of the rod 16, so that the cover 9 constitutes a stop limiting the movement of the magnet 15 upwards during its removal from housing 12.
- the upper end of the rod 16 carries a handle 17 which allows the magnet 15 to be raised by hand in the housing 12.
- a electric jack shown schematically in 18, allows, as a variant or in addition, to mechanically control the lifting of the rod 16, driving with it the magnet 15 out of the housing 12.
- the magnet 15 is constituted by a cylindrical bar with permanent magnetization, made up of very strong magnets base of ceramic material, covered with a steel casing stainless.
- the metallic particles of the mud magnetic are very fine (of the order of a micron) or in the case where the liquid to be sludge has a high viscosity, we can use advantageously magnetic bars made up of magnets neodymium.
- a stop piece 21 which is fixed in the enclosure 2 against the outer wall of the housing 12, at a level which is slightly higher than the face upper of magnet 15 when it is in the active position of attraction magnetic sludge ( Figure 1).
- this piece of stop 21 is constituted, as illustrated, by a disc annular, welded to the outer wall of the housing 12, which is produced in a non-magnetic material. The width of this stop piece is large enough that all of the magnetic sludge accumulated which go up with the magnet when it goes in its position shown in Figure 2 are retained below of this abutment piece 21.
- the enclosure 2 has, in its lower part a drain opening 7, located substantially below the housing 12, so as to provide a settling zone for the sludge in the bottom of the enclosure. Opening the drain opening is controlled by a valve 8, manually operated or mechanical, preferably consisting of a solenoid valve remotely controlled. Note that the drain opening is advantageously located vertically in the housing 12, where they fall magnetic sludge coming off the walls of the housing the magnet when it is removed.
- valve 8 is controlled when opening the bottom from the enclosure to a sludge evacuation pipe therein filed.
- the sludge magnetic retained on the walls of the housing 12 tend to go up with magnet 15 when you lift it, and they accumulate under the stopper piece 21.
- the magnet is sufficiently raised, there is no longer any attraction on the sludge magnetic, which remained under the stop piece 21, and they fall to the bottom of the container 2 to be discharged through the opening 7.
- the emptying operations are performed automatically at regular intervals maintenance.
- the valves 5, 6 and 8 are controlled to distance, automatically.
- they are advantageously constituted by solenoid valves.
- the automatic emptying procedure takes place from preferably as follows. Solenoid valves 5 and 6 are first closed and the magnet 15 is raised. Then we open the solenoid valve 8 and, after a time delay ensuring complete emptying of the enclosure, the inlet solenoid valve 5 is also opened so that to perform a rinsing causing all the sludge deposit towards the evacuation pipe. The solenoid valves 5 and 8 are then closed, then the rod 16 is lowered by means of the electric jack 18 to find the operating position of Figure 1. We can then open the two solenoid valves 5 and 6 and the circulation of the heating in the sludge removal device can resume.
- the sludge is collected on surfaces which remain stationary, the movable magnet being out of any contact with the liquid to sludge, and they are evacuated without the slightest scraping these surfaces.
- the configuration particularly compact device according to the invention described in example in which, in particular, the valves provided at the inlet and outlet of the annular circulation volume around the housing of the magnet are located at a level above the disc used to retain magnetic sludge during emptying operations.
