Definitions
- the present invention relates generally to exchangers heat, and, for example, tubular heat exchangers forming condensers, which are continuously cleaned by solid elements, in practice in the form of a ball and made for example of foam rubber, systematically put into circulation for this purpose in one of the flows concerned.
- the present invention relates more particularly to the management of the elements cleaning solids thus used.
- this management involves, basically, on the one hand, to avoid that, with the flow that carries them, the solid cleaning elements in question are evacuated to the sewer, the interposition, on the outlet pipe of the heat exchanger, of means of interception specific to their detention, and, on the other hand, recycling, towards the inlet pipe of the heat exchanger, solid elements of cleaning thus retained by these means of interception.
- this management device For its proper functioning, this management device needs to be crossed by a given flow flow.
- a management facility for solid elements has been proposed. cleaning circulating in a heat exchanger-for cleaning thereof, of the kind comprising means of interception which, specific to the restraint of solid cleaning elements in circulation, are interposed on the pipeline outlet of the heat exchanger, a return line, which recycles to the inlet pipe of the heat exchanger a return flow containing the solid cleaning elements retained by the interception means, and, arranged on this return pipe, a device for managing these elements cleaning solids, installation in which between the means of interception and the management device, is interposed, on the return line, a concentration device dividing the corresponding return flow in half parts, namely, a first part, or main part, which contains normally all solid cleaning items, and that is directed to the management device, and a second part, or derived part, which is normally free of any solid cleaning material, and which is removed from the management system, the return line belonging to means of circulation which are capable of generating, locally, through means of interception, circulation against the current.
- the management device is spared part of the flow rate return concerned, while normally seeing all the elements scroll cleaning solids to manage.
- the concentration advantageously makes it possible to systematically recreate the input of the management device, determined flow conditions, which correspond to its normal operating conditions.
- the subject of the present invention is a installation of the above kind characterized by the fact that the means of circulation include suction means adapted to resume, for their recycling, in accordance with the means of interception, the solid elements of cleaning retained by them, the concentration device being shaped general cylindrical and comprising a grid mounted to pivot about an axis that it presents in its central part so that it can occupy at least two extreme positions, a so-called “cleaning” position in which it leaves free passage of the main part of the return flow and intervenes in the passage of the derivative part of said flow, and a position known as "excluding cleaning” in which it is interposed in the passage of the main part and the part derived from the return flow.
- the circulation means comprise a pipe inlet established between the heat exchanger outlet pipe and its inlet pipe and connected to the suction of a pump which discharges into the concentration device.
- the management installation comprises a recycling which directs the derivative part of the return flow on the pipeline of heat exchanger outlet; the recycling line connects to the supply line via the concentration device.
- Concentrating devices with tilting grids have already been proposed; more specifically, there is a concentration device in which two grids arranged in a V are pivotally mounted about an axis which they present in their central part and can occupy at least two positions in V, the tip of the V being at the bottom for one of these positions and at the top for the other ; such a concentration device has the disadvantage that cleaning elements are lost during said recovery operation elements.
- the concentration device is connected to the recycling through a filter; thus, any loss of cleaning element is avoided.
- the filter comprises a tubular wall which crosses axially sealing an enclosure, the part of the tubular wall located at the interior of the enclosure being provided with perforations; the tubular wall of the filter communicates with the concentration device via a valve.

- tubular heat exchanger which, by example, is of the type succinctly described in document FR-A-2 716,530 mentioned above.
- filtration means 13 are interposed on the inlet pipe 11, by means of a cuff 14.
- these solid cleaning elements are systematically injected into the inlet pipe 11, downstream of the filtration means 13, to be driven by the incoming flow.
- a wheel 20 which closes the cuff 15 transversely and has, radially, between its axis and its periphery, a filter panel 21, which, under the control of means 22, is rotatably mounted about its axis, and, on the other hand, a horn 23, which is arranged in line with wheel 20, upstream in the direction of outgoing flow through outlet pipe 12, facing the panel filter 21 of the wheel 20.
- the management installation 18 comprises circulation means which are suitable for locally generating, through interception means 17, at right of the fallopian tube 23, a circulation against the current, and which comprise, themselves, to do this, on the one hand, an inlet pipe 25, connecting more precisely at the horn 23, arranged upstream of the means interception 17, and, on the other hand, a return line 28, which recycles to the inlet pipe 11 of the heat exchanger 10 a return flow containing the solid cleaning elements retained by these means interception 17, and on which is arranged a device 26 for managing these solid cleaning elements, in particular for checking the number of these, of the elimination of those whose dimensions are no longer sufficient, and a replenishment of solid cleaning elements new.
- a concentration device 27 capable of detecting the concentration of the corresponding return flow of solid cleaning elements.
- a device for concentration 27 dividing the corresponding return flow into two parts at know, as shown schematically by the arrows P1, P2 in the figure, a part P1, or main part, which contains all the solid cleaning elements in traffic, and which is directed to the management device 26, and a second part P2, or derived part, which is devoid of any solid element of cleaning, and which is moved away from this management device 26 and directed towards the outlet pipe 12 of the heat exchanger 10 via a line 29 called recycling; more precisely, in this form of implementation, this recycling line 29 is connected to the outlet sleeve 15; more specifically, again, the circulation means comprising a pump 24 of which the suction is connected to this inlet pipe 25, the recycling pipe 29 connects downstream of this pump 24 to the concentration device 27 itself connected to the pump outlet 24.
- the main part P1 corresponds to a minority of the flow of back processed, and the derivative part P2 to a majority of it.
- the main part P1 is at relatively low speed, and the derived part P2 at relatively high speed.
- the return pipe 28 dessert in the cuff 14, nozzles 32 which provide injection, in the incoming flow, solid cleaning elements to put back in or put in circulation in it, and which, preferably, are oriented against the current.
- the management device 26 does not fall under the present invention, it does not will not be described in detail here. It will simply be noted that the management 26 includes two compartments separated by a grid 39, a first compartment 41 into which the second section 37 opens and a second compartment 42.
- the two compartments 41 and 42 are connected, inter alia, to a distributor 43 for supplying the nozzles 32, the first 41 via a valve 44, the second 42 by means of a non-return valve 45.
- a pipe outlet 33 connected to the recycling line 29, therefore to the outlet line 12 of the heat exchanger 10, for evacuation of the debris retained by these filtration means 13.
- the device concentration 27 is generally cylindrical and has a grid 35, for example made up of bars whose spacing is less than the diameter solid cleaning elements; grid 35 is pivotally mounted around of an axis which it presents in its central part so that it can occupy at least two extreme positions, a so-called “cleaning” position, shown in solid lines in the figure and in which it leaves free the communication between the arrival pipe 25 and the management device 26, that is to say the passage of the main part P1 of the return flow, while it is interposed in the passage of the derived part P2 of said flow, and a position called “excluding cleaning", shown in dotted lines in the figure, in which it intervenes both in the passage of the main part P1 and in that of the derivative part P2, that is to say over the entire return flow.
- the device for concentration 27 is connected to the recycling line 29 via a filter 50.
- the filter 50 comprises a tubular wall 51 which passes axially through a sealed enclosure 52; the tubular wall 51 communicates, on one side, with the lower part of the concentration device 27, via a valve 53, and, on the other side, with the outside, also via a valve 54; the part of the tubular wall 51 located inside the enclosure 52 is provided with perforations; the conduct of recycling 29 is connected to the external wall of the enclosure 52, to the part lower thereof, to the right of which it is closable by a valve 55; the upper part of the enclosure 52 carries a closable vent 56.
- a non-return valve 46 and a valve 47 are also arranged on the recycling line 29.
